effective utilization of resources slag magnetic separator magnetic effect

Slag magnetic separator magnetic mineral particles only after magnetic separation. Weakly magnetic minerals and the ferromagnetic minerals due to its chemical composition and crystal structure is different, it is different from the magnetization characteristics

Composed of many magnetic domains, according to market forecasts, our magnetic separator when the 2008 market size of about 11 million, in 2009, China s coal mining and washing industry, the total size of the construction

An increase of 53.1%, 84.4% of the net increase in built size, showing a strong momentum of growth. If the reduced magnetization H, J magnetization decreases compared, but not along the

The original curve, but is decreased along the curve than the original, if the magnetizing field strength H is reduced to zero, J does not drop to zero, while retaining a certain value Jr, the number of

Value is called remanence, a phenomenon known as hysteresis, J in order to reduce to zero, and needs a reverse magnetic field, the strength of the coercive force Hc is called.

According to various minerals than the susceptibility differences, and different magnetic field strength slag separator machine, generally divided into three categories. Weakly magnetic minerals than the magnetic

Coefficient of 15 - 500 * 10-6 cm 3 / g, such as hematite, limonite, and other methods using magnetic separation recovery. Strong magnetic minerals than the susceptibility greater than 3000 * 10-6

Cm 3 / g, such as magnetite, pyrrhotite, etc., with a weak magnetic separation equipment that is able to effectively separate and gangue minerals. Magnetic minerals than the susceptibility of 500 -

3000 * 10-6 cm 3 / g, such as semi-illusion hematite and ilmenite, etc., with the magnetic field magnetic separation equipment for sorting.

Slag separator Henan Yu Fa Machinery Co., Ltd. is slag beneficiation designed magnetic separation equipment, mineral processing equipment for slag traditional screening inadequate Yu licensing

Slag separator greatly improved the appearance of slag screening efficiency, improve the efficient use of resources, but also by users unanimously approved, are detailed below under the slag magnetic

Sorting machine should be noted that the use of the principles and maintenance measures:

⊙ focus associated with the magnetic machine before and after the device task conditions, especially in front of weakening, magnetic knife holders slag and other operations must be running. Timing replace oil.

⊙ dielectric plate pleaded not string is not blocked, adhere cl eaned once 20 to 30 days, regular replacement dielectric plate (for example, one year or six months depending on the condition of the tooth plate abrasion), and focus on pressure

Cover screws to tighten.

⊙ task focused oil and cooling oil temperature rise is too high to be reported to the workshop director, in order to adopt the necessary measures, such as downtime. Gearhead temperature super-

Limit should immediately report the workshop leader, parking View disposition.

⊙ focus on investigating the oil pressure gauge, pressure gauge, voltmeter, ammeter pointer whether sensitive tool holderreading ability to meet requests, identify problems and timely disposal to find relevant personnel

.

The so-called slag separator working gap, that is the spacing of the cylinder and the tank. This spacing is the size of concentrate quality factors affecting choose ano ther one. If the slag machine

The gap is too small, that tube skin and too close to the tank, the slurry flow through only did he not affect the processing capacity, and because space is too small, it will make regardless of the size of the magnetic

Particles will get ample opportunity to breathe drum skin. Mainly due to the magnetic field from the pulp is too close, the magnetic field caused by the high strength. However, to reduce tailings grade increase the recovery rate

Is good.

If the spacing is too large, can only make a strong magnetic pick up particles, weaker on the election does not come up, Wet Magnetic Separator although concentrate grade, but also increases the tailings grade

, Reducing recovery. Therefore, adjust the working gap slag machine is very important. Field production will generally need to be adjusted according to the working gap in t he range of 35-60 mm

, The working gap angle bracket can be adjusted to change the bottom gasket gap size.

Type
Plastic additives according to their specific functions can be divided into seven categories:
① to improve the processing performance additives such as heat stabilizers, lubricants and the like.
② improve machining performance additives, such as plasticizers, toughening agents, etc.
③ additives improve the surface properties, such as an antistatic agent, a coupling agent.
④ improve optical performance additives such as coloring agents. ⑤ improve the aging properties of additives, such as antioxidants, light stabilizers.
⑥ reduce the cost of plastic additive , such as extenders, fillers and the like.
⑦ impart other specific effects of additives such as blowing agents, flame retardants, fungicides and so on.
Additive is dispersed in the molecular structure of the plastic, the plastic will not seriously affect the molecular structure, and can improve the properties or

reduce the cost of chemicals. Additive to be added, can promote improved plastic substrate processing, physical, chemical and other functions and increasing

Substrate physical and chemical properties.
According to the pvc additive to improve functional differences, there are many different titles additives.
Specifically, from the increase of the processing characteristics of the substrate, additives include: ① Liquidity: sl ip agent; ② thermal stability; ③ heat

stabilizers, antioxidants; ④ dispersion: processing aids, dispersants; ⑤ compatibility : Compatible, coupling agents; ⑥ melt strength:

nucleating agents, health of: antibacterial agent. Additives are mainly the following categories: 1, antioxidant

Agent (Antioxidant) unsaturated double bonds in the plastic by an oxygen atom, the invasion of heat and light, free radicals cause fracture, thereby causing a chain

reaction, the molecular chains or the formation of the crosslink, resulting in reduction in strength of plastic products or brittle. Antioxidants function

Is that the delay can be due to oxidation and decomposition of the plastic, extending the life of plastic products.
Used in the plastics industry antioxidants can be classified according to function: (1) the oxidation chain reaction inhibitors: eg alkylphenols (Alkyl phenol),

butylated toluene (Butylatedhydroxytoluene referred BHT), aromatic amines (Aromatic amines),

Phenyl-B-resistant amine (Phenyl-B-Naphthylamine), alkyl of Kun (Alkyl Quinone), an alkenyl group of bisphenol (Alkylene bisphenol), alkylphenol sulfide (Alkyl

phenolthioether), salicylate, phenyl means (Phenyl salicylate )

And so on. (2) peroxide decomposers: alcohols such as Liu acute thioether sulfur propionate (Thio propio nate ester), an organic phosphorous compound.

Activated carbon filter

The role of the activated carbon filter is to remove macromolecular organic matter, iron oxides, chlorine. Organic matter, chlorine, iron oxides easy to make ion exchange resin poisoning, chlorine, cationic surface active agent will not only make the resin poisoning, but also destroy the membrane structure, so that the failure of the reverse osmosis membrane.

The active carbon filter is the use of activated carbon having a rich pores on the macromolecular organic matter in the water, chlorine, iron oxide colloid adsorption filter, this absorption is not reversible, i.e., activated carbon saturated adsorption capacity, once saturated adsorption, activated carbon loss of adsorption performance, can not be the backwash method rushed pollutants. In addition, activated carbon adsorption of organic matter, bacteria rich in nutrition, resulting in a large population of bacteria within the activated carbon filter, but increased the microbial content of the water by activated carbon filter.fabric filter

Before activated carbon adsorption saturation, backwash on a regular basis to a large number of bacteria group out of the surface of activated carbon and suspended solids. They should immediately replace it with a new activated carbon, activated carbon adsorption saturation, otherwise it will cause irreparable damage of the reverse osmosis membrane.

Water Softener

The role of the water softener is the removal of calcium and magnesium ions, the water is softened. If no softener or softener VALID, calcium, and magnesium salts in the surface of the reverse osmosis membrane is formed due to a sharp rise in the concentration of the water-insoluble precipitate, plugging the hole of the reverse osmosis membrane, the reverse osmosis membrane life shortened.bag filter manufacturers

Built water softener for ships with a sodium cation exchange resin, the exchange resin is saturated with brine regeneration. Resin degree of fragmentation is getting worse after a few years of use, gradually lose the ability to soften. Especially when the active carbon filter saturation adsorption but not timely replacement of activated carbon in raw water iron, organic matter, chlorine directly into the water softener resin poisoning, poisoning, the resin will not be able to use renewable way to restore activity, , replace the resin when the resin exchange capacity decreased.

Pure water equipment selection and maintenance of the filter

The face of the market a wide range of assortment of pure water equipment, we should be how to choose and maintain water equipment?fabric filter

Strainer by the size of the filtered water, the most common sand filter, non-woven filter filter and PP fiber filter, filter, the nonwoven filter and the length of the PP fiber filter is the most commonly used 10-inch and 20-inch two, as a coarse filter with a pore size of the filter should generally be about 25u.

The role of the coarse filter is to remove suspended impurities larger particle size in water, to avoid these impurities into the activated carbon filters, covering the surface of the activated carbon, the pore structure of activated carbon adsorption of impurities in the water is lost.bag filters

Strainer with the rejection of solid impurities increase the resistance sharply rises, the water flow is gradually decreased. Without timely treatment, can not meet the water flow requirements for follow-up treatment processes. Sand filter, pressure increases to a certain extent after backwash. Backwash some fine sand out of the filter, sand filter should be regularly supplemented with sand, sand after repeated backwash, the degree of fragmentation increases, at the same time each backwash impossible to rinse sand the remaining sludge is gradually increased, the sand will appear the phenomenon of "compaction", you should replace the sand. Non-woven or PP fiber filter, filter pore clogging generally difficult to rinse with water, shall replace the filter on a regular basis.

Principle of air filters

Collision and stick

Dust particles in the air, or coasting with the flow, or do random motion, or by some kind of field force and movement. When the movement of the particles hit the obstacle, the van der Waals forces between the particles and the obstacle surface so that they stick together.air filter bag


Fiber filter material
The filter material should be able to: effectively intercept dust particles, the air flow without much resistance. Non-woven fibers and special paper meets this requirement. Intricately interwoven fibers formed numerous dust barrier between the fibers spacious space allows air flow through smoothly.

The principle of inertia

Inertial motion of large particles in the gas stream. Airflow Obstacle bypass particles deviate from the direction of air flow due to inertia and hit the obstacle. The larger the particle, the stronger the force of inertia, the greater the possibility of colliding with obstacles, so the better the filtering effect.

Diffusion theory

Small particles random Brownian motion. For mathematical processing of the irregular movement and mass diffusion theory, diffusion theory said. The smaller the particles, the random motion of the more dramatic, the more chance of colliding with obstacles, so the better the filtering effect.bag filter

Efficiency varies with the size of dust particles
The filters trap amount of dust and unfiltered the ratio of the amount of dust in the air is "filtration efficiency". Less than 0.1um (micron) particle for diffusion motion, the smaller the particle, the higher the efficiency; greater than 0.5um particles for inertial motion, the larger the particle, the efficiency of Zhao Gao. Between 0.1 ~ 0.3um, the efficiency of a the lowest point, the particle size of dust, the most difficult to filter.

Resistance

Fiber bypass airflow, resulting in a slight resistance. Resistance of numerous fiber is the filter resistance. Filter resistance increased with increasing gas flow through the filter of the relative wind speed can be reduced by increasing the area of ​​the filter material, to reduce the resistance of the filter.

Dynamic performance

The dust capture additional resistance to air flow, so, use the filter gradually increasing resistance. Capture dust filter media together as one to form a new obstacle efficiency of filtering, a slight improvement.

And capture most of the dust gathered in the windward side of the filter material. Greater filter area, more dust can accommodate, the longer the life of the filter.

End-of-life of the filter

More dust filter, the greater the resistance, filter life coming to an end when the high resistance to design not allowed. Sometimes, too much resistance causes the filter to capture dust flying, this risk, the filter and the scrap.

Static electricity

If the filter material with electrostatic powder with electrostatic filter effects can be significantly improved.

The reason: the static electricity the dust trajectory and make changes into obstacles, static electrostatic force stuck.

Removing the air filter

Weird weather but also to the breeding ground for bacteria, especially the part of the home split air conditioner indoor unit, Austrian Zhejiang Electric Co., Ltd., filters, heat sink and out of the wind wheel on the buildup of dust and dirt. These dust is not only a breeding ground for harmful bacteria, to produce odor also seriously affected the air quality. Traditional air conditioning, cleaning can simply rinse filter, wipe the surface of the evaporator, PAM gap on the air conditioning evaporator and air supply system can not wash thoroughly, inside the evaporator is clogged with dust is the most serious, most likely to breed bacteria, viruses place. belt filters
The researchers detected within the air-conditioned including Legionella bacteria, Escherichia coli, Staphylococcus aureus, and other pathogenic viruses and bacteria. The easiest approach is to directly buy air conditioning disinfectant treatment. The research shows that nearly 90% of home air conditioning excessive bacteria. In addition, a long stay in air-conditioned environment, easy to suffer from the "Air conditioning disease". "Air conditioning disease" accompanied by dizziness, fatigue, nausea, stuffy nose and other symptoms. Only deep cleaning air conditioning can greatly reduce the parasitic viruses and bacteria. filter fabric
The specific method is: Select a dry and sunny day, the air conditioning function keys of operation 3-4 hours in the air state PAC, so that the air conditioning internal moisture distribution dry. Then turn off the air conditioning, polyacrylamide, unplug the power cord, air-conditioned enclosure dirt with a soft, dry cloth to wipe, can also be cleaned with warm water, but do not scrub with hot water or flammable oil, chemicals. At the same time, remove the air conditioning filter, clean the filter with disinfectant, dry reload air conditioning. When the outdoor unit is clean, rinse with water the outdoor condenser surface, to be dry after the hood cover other parts of the non-water.

How to choose the baghouse filtration velocity

Baghouse filtration velocity size determines the size of the baghouse overall operating efficiency and cost. Therefore, we have to understand how to select the size of the filtration velocity.

Filter the size of the wind speed is mainly determined by the traits of dusty gas, fabric categories as well as the nature of the dust, under normal circumstances are selected in accordance with the dust removal equipment recommended sample data and practical experience of the user. Pulse baghouse filtration velocity of about 1.2 to 2m / s, glass fiber bag filter filtration velocity of approximately 0.5 to 0.8 m / s. The main selection parameters are the following.fabric filters

A. Type cleaning method according to the different types of dust

Carbon black, silica (white carbon), aluminum, zinc sublimate remaining gas in the gas formed due to condensation and chemical reaction solution, activated carbon is discharged from the cement kiln cement. Filtration velocity of 0.25 to 0.40.3 to 0.50.33 to 0.600.8 to 1.2 m / s.

Sublimate of iron and ferroalloys, foundry dust, alumina, cement mill discharge cement, the carbonization furnace Cheung Wah matter, lime, corundum, plastic, iron oxide, coke, coal. The filtration velocity 0.28 to 0.450.4 to 0.650.45 to 1.01.0 to 2.0 m / s.

Talc, coal, blast cleaning dust, fly ash, ceramic production of dust, carbon black (secondary processing), a pigment, kaolin, limestone, mineral dust, bauxite, cement (from the cooler). The filtration velocity 0.30 to 500.50 to 1.00.6 to 1.21.5 to 3.0 m / s.

II. According to the number of bags

Calculated the total filtration area and the area of ??the single dust bag, you can calculate the bag number. If the the bag room number of each bag is determined, you can also calculated the entire precipitator room number. Although the the precipitator design or selection in the need to determine the number of rooms, but the site layout and easy maintenance considerations, often more than six rooms in addition to sitting room as the double row. Less than 5 chamber precipitator of each chamber is given as a single row.dust filter

Selected parameters, dusty gas flow, the nature of the concentration and dust dispersion, wettability, viscosity, etc. In addition to the above two are selected the baghouse filter wind speed parameters. Understand these parameters, we can easily select the size of the baghouse filter wind speed in order to improve the operating efficiency of the dust collector, thereby reducing costs.

The commissioning steps before the bag pulse dust collector is running

Pulse jet bag filter industrial wider application of a dust removal equipment, it is more advanced in cleaning technology. Deal with large amount of wind, small footprint, high purification efficiency, reliable operation, simple structure, small amount of maintenance features, its collection efficiency can reach more than 99% efficient dust removal equipment. Pulse jet bag filter is put into operation, the various components of the equipment needed for testing, debugging. The specific debugging steps:fabric filters

Step 1: Check the transmission part (ash body) of a foreign body, and then turn on the wind power switch, check the direction of rotation of the airlock, ranked ash auger runs smoothly without abnormal noise, to ensure the normal operation of the time by observing not less than 0.5 hours.

Step 2: Check the support of the process piping connection is stable solid, and check the filter bag installation is solid, has good sealing.

The third step: Make sure the power and air supply connections are correct on, open the pulse controller checked in order to verify the line of control and digital display connection order of the solenoid valve, confirm the solenoid valve according to the sequence of actions is correct.bag filter manufacturers

Step 4: observe the operation of the solenoid valve is sensitive and reliable switching sound is clear disorder phenomenon, the injection time of the pulse valve opening degree is consistent.

In addition to the frequent fog and haze days for healthy fresh air misunderstanding

As the days of haze struck from time to time, many consumers pay special attention to not open the window to achieve ventilation fresh air system, the haze day be able to use the new air system? Installed a new air system will be able to give room ventilation? Many consumer misunderstanding and confusion still Current reporters asked the experts point out some fresh air system in the installation and use of a variety of misunderstanding.air filter bag

Myth # 1

The haze days can open new air system ventilation

Some consumers believe that fresh air system is to give indoor ventilation Well, since the days of haze can not open the window, open fresh air system is also very good.fabric filters

Answer: Reporters learned that a number of experts, fog and haze days, it is recommended that owners of interior doors and windows closed until the air quality improves the ventilation window. Fresh air system is piped through outdoor air introduced into the room, and then polluted indoor air into the room. According the Sunderbans HVAC Equipment Co., Ltd. (China) ACBEL new wind integration division manager Yang Zhen introduced the new wind in addition to the large-scale similar to a central air conditioning system as a whole new air system can be installed HEPA (high efficiency filter can filter out the air in the PM2.5), the normal ventilation in the fog and haze days, other bedroom To install HEPA fresh air system costs need to test the air pressure of the products, some relatively complex. Therefore, the room fresh air system default filter layer for large particles of dust and other pollutants, in this case, it is recommended that owners haze days do not open new air system ventilation.

The spring recommended maintenance parts

Wiper: more rain in the spring, the wiper frequency of use will be significantly increased. Check wiper rubber in the winter because of the low temperature cracking, once discovered to be replaced immediately, so as not to scratch the windshield wiper.

Tires: long-distance travel increased to give the tire a burden to tire a systematic overhaul work, ran a few long-distance, it is best to do a wheel alignment, if it is four-wheel-drive SUV with particular emphasis on this point. The work of the tire is good or bad will affect the safety of vehicles and fuel economy.fabric filters

Chassis: muddy roads open in the winter after the snow, the chassis will be stained with dirt. Some of the substances in the soil of the car chassis corrosive, sometimes block the ventilation holes, if long-term car wash, car wash in the spring, be sure to chassis soil rinse.

The Spring should focus on vehicle air cleaning

Today, many owners have noticed that winter give the car for the antifreeze, but warmer temperatures, they do not pay attention to a corresponding adjustment to the car. In this regard, professionals advise, spring conservation of the car, the air conditioning systems, vehicle interior should start to focus on solving the air inside the vehicle clean.

Shanghai spring temperature peaks and valleys in, adjacent two days the temperature difference is likely to more than 10, cold air conditioning is likely to soon indirect heat air conditioning classes "posts". The most family cars cold air conditioning has been disabled for six months, until it is enabled, the best wash the condenser and radiator, and check refrigerant margin, if any should be promptly added. In addition, a large number of pollen and other allergens in the air spring, air conditioning air inlet filter should be clean or replace.

In addition, the automotive engine air filtration system in the spring should raise the frequency of inspections, in order to avoid air filtration system is blocked by dust, sand and makes the engine difficult to start, idle instability and other problems.bag filter manufacturers

Throughout the winter, the owners window ventilation time are shorter, failed to clean up the residue in spring suitable temperatures can easily lead to the breeding of bacteria and mites, sometimes moldy smell. For the sake of clean interior environment, good thorough cleaning and disinfection of the cushion, floor mats and other interior and the interior environment, regular cleaning of the trunk debris.

The Spring auto focus maintenance should pay attention to cleaning air conditioning wipers

Spring is the peak season to travel by car, but during that time to the car maintenance is relatively small. Reporter yesterday learned from a number of 4S shops and auto repair factory, due to a lot of owners in the winter just past been adjusted for the car, so in addition to do routine maintenance customers, the owners of recent maintenance can be described as very few . In fact, the spring, warmer temperatures, microbial begins to accrue, whether it is ordinary interior or more complex air-conditioning system should do a good job cleaning and maintenance.fabric filters

Electrophoresis equipment system with the process

The electrophoresis equipment including electrophoresis tank, spray tank, electrophoresis power supply electrophoresis recovery ultrafiltration, electrophoresis coating equipment, plain, high light and color, electrophoresis equipment in most cases is mainly used for automobiles, household appliances and a variety of iron and steel parts corrosion coating. This paper describes the optional method of electrophoresis equipment and affect the coating process parameters, as follows:water filtration cartridge

The first step: we must first understand the basic process of the electrophoretic coating equipment;

Step 2: To learn electrophoretic coating equipment must have Electrophoresis Equipment Required equipment: the electrophoresis tank electrophoresis power supply (also known as the rectifier cabinet), electrophoretic oven, electrophoresis ultrafiltration machine, wash tank.

Methods and techniques of electrophoresis coating equipment:

(1) general metal surface of the electrophoretic coating, the process: pre-clean-up → Online → degreasing → ??washing → rust → washing → ??→ washing → ??phosphate → washing → passivation → electrophoretic coating → ??tank cleaning → the ultrafiltration water washing → ??drying → ??off the assembly line;

(2) of the substrate to be painted and pre-treatment has a tremendous effect on the electrophoretic coating. The castings generally use grit or shot blasting rust remove loose dust on the surface of the workpiece, cotton yarn, 80 # ~ 120 # sandpaper to remove surface residues steel shot and other debris. Steel surface degreasing and rust treatment, surface requirements too high, phosphating and passivation surface treatment;bag filters

(3) Usually, in the filtration system, using a filter, the filter a mesh bag structure, a pore size of 25 to 75 microns. Electrophoretic paint through the vertical pump fed to the filter to filter;

(4) The size of the amount of the circulatory system of the electrophoresis equipment coating cycle, a direct impact on the stability of the bath and the quality of the film. To increase the amount of circulation, precipitation and air bubbles of the bath to reduce; bath accelerate the aging of the increase in energy consumption, deterioration of the stability of the bath;

(5) With the extension of production time, the impedance of the anode separator will increase the effective working voltage drop

Consumers need to guard against the concept of Fudge

Close to 51 in summer to start selling air conditioning. Appliance stores, air conditioning with air purification stood before the people, seems to have become the first choice of consumers. However, consumers need to guard against air-conditioned store "concept" Fudge.surgical sutures

A consumer stores in addition to the publicity of the PM2.5 features air-conditioned, they do not understand the principle of air purification, is just a concept, the actual effect is not very clear. The reason why consumers choose these high-priced products, is based on the principles of results-oriented. After all, buy a cleaning air conditioning is equal to have an air conditioner and an air purifier in one machine. Save money at the same time, but also to bring the most important healthy living.

So what about the worries of consumers, whether the air-conditioning business opportunity for the concept of speculation? Air purification function results in the end, the ability to replace professional air purifier?

In this regard, the National Indoor Environment and Indoor Environmental Quality Supervision and Inspection Center Director Song Guangsheng, in addition to the formaldehyde air conditioning in the technical principle is easier to achieve, but the removal of PM2.5 and other solid particles still awaiting a breakthrough in technology. He noted that the air purifier remove PM2.5 solid particles is installed and efficient, but the filter itself bulky, especially for air conditioning can not be installed directly hook.blood transfusion set

Ovid Consulting Research Institute Yanbin that the rigid technical support and consumer demand, air conditioning with air purification function or replace the air purifier.

The purifying air conditioning 30% more expensive

    Gome, Suning Appliance stores, sales staff said the surge in sales of recent air conditioning with air purification function. As such products are basically high-end products, the price with the specifications than ordinary air conditioning expensive by 30%, most of not less than 4,000 yuan, or even million.

    TCL air-conditioned area, said the launch of the 2013 new "Athena" series, equipped with a 360 ° purification system, air quality monitoring, Taina sterilization double in addition to formaldehyde, the full range of strong ventilation function to detect and eliminate bedroom for sulfur dioxide, nitrogen dioxide, carbon monoxide, ammonia, ozone, formaldehyde, benzene and other pollutants, keeping indoor air healthy and clean. Therefore, the initial price positioning in the $ 15,000. disposable scapel

    Coincidentally, Hisense Kelon recently listed apple pie A8 air conditioning, Gree remove the PM2.5 air-conditioned U statue series, Panasonic equipped with nanoe-G new air cleaning technology Relatively speaking, the price is not low.

    However, despite the price increase to the next level, but does not prevent the purchase needs of consumers. Suning stores sales staff said, in fact, with governance, PM2.5 air conditioning in the last year, was launched in the sales market is not good, average weekly can sell a. But now, an average of 3 days will be able to sell one than before, more than doubled.Laparotomy sponges

The air purifier market is a huge cake

The air purifier market is a huge cake. Indoor harmful substances, including formaldehyde, benzene, ammonia, radioactive radon, growing pollution levels, the body will produce sub-health response, even life-threatening.

    The statistics, people daily average of about 80% of the time spent indoors. With the more modern lifestyle, more work and cultural and sports activities in the indoor Activity of the people in the room and even up to 93%.

    Began in the home appliances can solve indoor air pollution has a great potential market demand. surgical suture

    The major air conditioning companies as a "need"

    Previously, the dreaded haze gave birth to the the PM2.5 economic phenomenon, air purifier became the best-selling home appliances in the moment. Despite the high prices of air purifiers, the hundreds of thousands or even million, but its air purification function is consumers are most concerned about, and their pay.

    In the face of this huge emerging market, the major air conditioning companies playing the mind, have launched cleaning air conditioning, start the Nuggets air purification market. Air conditioning, has been upgraded into an air-conditioned + air purifier "dual function" drive.

    At present, TCL, Haier, Gree, Zhi Gao, Hisense and other brands are market related products. The air-conditioned third-generation TCL titanium silver ion antimicrobial, Haier-heavy air purification system, A8 equipped Hisense apple pie the HiFD efficient purification technology "and so the main air purification technology licensing market. Disposable Hypodermic Needle

    TCL air conditioning, product upgrades, stressed air purification function, the needs of the market. The future, the air conditioning will no longer only a single thermostat function, equipped with air purification function will be an inevitable.

The performance of the role of home water purifier in the United States

A century ago, not only in the United States, fears of water-borne disease, microbial diseases and other acute health effects of drinking water, water purifier water treatment rules focus on the long-term health impact. Under normal circumstances, if the water meets the safety standards for drinking water, can be safe to drink. In addition, most consumers purchase and use water purifier filters, but also to improve their water taste, odor and impurities, taste better. So the demand for water purifier is inevitable.absorbable sutures

Another point worth noting is that some pollutants, will affect private wells, drinking water can penetrate through the purification of the lead in household plumbing or service line central processing facility. Consumers to buy a water filter can not only eliminate the health impact of harmful impurities, for home water purifier, you can also prevent water pollution defiled their taps. Otherwise, the home kitchen water purifier is not worth further pointed out that the investment in the drinking water.disposable gloves

Overall, the value and role of home water purifier is mainly reflected in the water quality to provide security, remove impurities enhance taste, provide a safe environment for domestic water.

Family water purifier Selection Considerations:

Ultrafiltration membrane filter carbon market a lot of whole house water purifiers energy stone: This machine has many shortcomings:suture needle

First carbon life in general in three months, the central machine Once installed to replace the filter is too much trouble, it is recommended that customers purchase the Central Water Purifier be sure to ask how the configuration of the Central Water Purifier: Average , the best configuration of the central water purifier filter: ultra-membrane KDF,

Third: For consumers: energy stone, and medical stone is just a selling point of the water purifier, flashy, and a lot of material there is not a food-grade material.surgical suture needles

In the United States, even if the pure drinking water, still contains trace amounts of carcinogenic pollutants, such as tetrachloro acetate, and trichlorethylene, epichlorohydrin and acrylamide. A spokesman for the Environmental Protection Agency immediately issued a drinking water standards, be sure to use a water filter technology and reduce risk. Even trace amounts of carcinogens can also encourage them to buy a water purifier filter system, because they should buy.

Water filtration

The rapid development in the water purification industry today, there are still people suspected the value of the water purifier, most of the water purifier or very strange, do not know there is no use in the home water purifier installed in the home water purifier There is no need? In fact, the water purifier is very useful, install water purifier is very necessary, and the water purification industry after more than 10 years of development has now become essential. Become part of the family a healthy life.industrial air filters

Water purifier, also known as a water purifier, water purification machine is used to filter tap water. Early market there is a water purifier called electrolysis of water. Principle obtained by electrolysis of water purification. This water ionizer has basically been out of the market, the early many businesses as a health product, false propaganda, after 2005 the national law of love has explicitly the still water purifiers cure health promotion, deceived consumers, to regulate water purifier market. All the water purifier have in common: the water through the filter material for screening, according to the filter material separation process.

Filter elements: water filtration process requires three conditions:

First: there must be water pressure

The second: to have the filter material

Third: to have waterdust collection filter bags

And tap water, the degree of separation of the impurities achieved according to the type of filter material is not the same:

Water purifier market for the next few years

With the increasingly serious problem of domestic water pollution, plus the farmer spring pull-out "water gate" incident, water purifier products is expected to be touted. According to reports, the water purifier has been described as "an air-conditioned class products" Some media said that this is the last piece of cake in the home appliance industry in the 21st century will be formed in the next five years 3,000 billion market size.water filtration cartridge

In fact, in recent years the development of the water purification industry in China is also very rapid, water purifier production growth rate of 42% -50% annually. As we all know, water appliances in foreign countries has become a very high penetration of household essentials. Relevant information, the water purifier penetration in developed countries generally more than 80%, while China's penetration rate of less than 5%.

Analysts pointed out that with the increasingly serious pollution of water resources, water purification industry will be promoted to a sunrise industry. Media reports indicate that, microfiltration, ultrafiltration water purifier, reverse osmosis water purifier water purifier on the market price ranging from 1800-6000; their food-grade material, the use of pure physical sterilization way. Five filter layer: the beginning of the filter layer adsorption layer, fine filter layer, a passivation layer, layer of odor, remove impurities, chlorine, bacteria, viruses, heavy metals, alkaline water, reverse osmosis water purifier Description purified water you can drink straight.air filter cartridge

It should be noted that the domestic water purifier on the market no one screamed loud brand. Said, "Which brand do not have problems. Similar production technology, similar to the material used, the basic filter, just propaganda, level of automation, packaging Zhao Feihong, director of the Beijing Association of health protection Health Professional Committee of drinking water."

Water quality problems cited concern

Junk Fortress Besieged "water source rumors have not dissipated, the the farmer spring of water quality problems and the emergence of new controversy. According to media reports, Ma Kam Ya, farmer spring executed in Zhejiang Province bottled drinking natural water the standard (DB33/383-2005) in a number of indicators below the national drinking water, drinking water, health of the China National Health Association Professional Committee of the Secretary-General health standards. "fiber glass filter

Media reports, the farmer spring quickly released a statement saying, the Nongfushangquan natural drinking water quality is always higher than any existing national drinking water standards, and denied media reports before. Last weekend, the farmer spring released a new statement, the first to admit that the national standard GB5749-2006 "drinking water standards" are all bottled drinking water must comply with the minimum standards, and claiming the company "products must meet GB5749-2006 life drinking water health standards (ie water standard), bottled drinking water standard GB19298-2003, DB33/383-2005 Zhejiang natural drinking water standards, so there is no implementation of the standard is lower than the so-called farmer spring water standards said. Farmer spring, stressed that there are two indicators or more stringent than the water standards for its implementation Zhejiang standard.

In this regard, the Secretary-General of the Chinese National Association of Health Ma Jin Asia pointed out that "We see a standard high and low, it is important is to focus on the indicators of the harmful, even if only one below the national standard, this standard is not as good as the national standard." Not to mention the Nongfushangquan standards on arsenic, cadmium, selenium, nitrate and bromate harmful to human health, key indicators are not such as tap water standards, especially bromate this indicator, the farmer Springs actually not performed by Zhejiang standards involved.non woven filter fabric

Nongfushangquan water quality issues controversy no results, this is not a "commercial war", this event or hit the general public is extremely concerned about the safety of life, that is, the quality of drinking water. According to Ma Jin Asian, and domestic drinking water there are different standards, the Association is involved in national food safety standards, stereotypes amendments to the packaging regulations for drinking water. Future, all the stereotypes packaged drinking water safety standards, should be included in the national food safety standards system.

How to correctly handle the car bacteria often kept clean car wash

Many people might think that in the car, shut the door window, is a confined space, then sprayed some perfume from the car clean and warm incense. Foreign scientists, this idea is wrong. It is precisely because the car is a confined space, bacterial growth than in the ventilated space faster and more pollution than the outside world is serious, this is not some perfume or deodorant sprays can be resolved.

Proper use within the circulatory system, not only can effectively inhibit the bacteria in the air conditioning pipe, but also to extend the service life of air conditioning to save fuel consumption. Rainy days, the owner can use within the circulatory system, the air conditioning filter is not easy to mold, thereby reducing the generation of bacteria in the air conditioning ducts.air filter cartridge

Usually use automotive air conditioning, five minutes before the car is turned off should be off the air conditioner, and converted into the inner loop. This will prevent air-conditioning water adsorbed on the air-conditioning on the wall, you can effectively eliminate air conditioning odor, but also can extend the life of air conditioning to save fuel consumption. Air conditioning ducts residual air-conditioning, so that the wind blowing or cold, heat intolerance friends do not have to worry about.

Summer season, the temperature gradually increased, car leather, plastic and other decorative objects also easy to emit some odor. After a spring and winter, the car is easy to "filth" because the car is often sealed exterior air circulation, dust particles easily attached to the leather chairs and ornaments gap pores . In this regard, it is recommended that, before the beginning of summer to the car as a sauna, cleaning car interiors, but also sterilization to remove car smell.dust filter

The summer car doors and windows closed, air conditioning. Therefore, many owners believe that, in the case of doors and windows closed, the car does not have dust, you can not wash. Actually, this is not the case. As long as the vehicle is traveling, there will be dust. So, the car interior cleaning must not be sloppy. We can every day with a damp cloth to rub automotive interior, especially the dashboard, steering wheel, door and other places. Or, at least a week to go to a professional car wash at the car wash, the car inside and out and are kept clean.

In addition to The garrison unit coal-fired boiler being further Mopai the outside, the city's various types of coal-fired boilers a total of 820, produced by burning coal, sulfur dioxide, nitrogen oxides, soot emissions total of nearly 200,000 tons. This year the city will invest nearly 50 billion yuan, removal of the 450 sets of 20 tons of steam boilers. Coal enterprises to promote the baghouse will be retained, in order to reduce emissions as much as possible.

The baghouse Product varieties is rising

Ordinary polyester needle felt filter bag because of the cooling effect of the external gas condensation, which not only make the trap dust fouling of the filter surface to clogging, but also can increase in the resistance of the dust collection device, which directly affect the dust removal equipment for normal operation. Water repellent and oil polyester needle felt dust bag can effectively prevent water and oil was echoed penetration leakage, and general media analogy, not only has water repellent and oil properties, also has anti-caking and ease of peeling and dust . dust filter bags
The research, design institutes and tertiary institutions in the study, the introduction, digestion, on the basis of transplantation, combined with the home and industry application needs and production plant developed a pulse bag filter for carbon black industry, not only as a dust removal equipment, Guangdong ESP as an indispensable process equipment; dust removal system of urban construction waste incinerator tail of dust, in addition to dioxins and other harmful gases, development and the introduction of a baghouse, baghouse product variety of the home and increasingly advanced , perfect, complete, close to the range of applications and the use of effects and abroad, some of them have reached the international advanced level. polyester sewing thread
Airborne dust containing more water and oil and moisture absorption and easy deliquescence dust the surface of the dust may be born of water film thereby increasing the adhesion, which of course helps trap dust, but will make cleaning thrown problems, especially the high-temperature gas is high humidity condensation more bag filter cleaning difficult pulse dust collector, cleaning is not complete. Dust accessories biggest drawback is the need to replace the filter bag, filter varieties poor quality, Bag sewing technology is not cross the border, as well as dust removal system for other reasons, for bags short period of filter bag and bag filter technology is the simultaneous development of production of chemical fiber woven room temperature needle felt, anti-static needle felt needle felt of oil-and waterproof, high temperature resistant to erosion needle felt and continuous glass fiber cloth precipitator fiberglass bulk yarn, glass fiber needle felt filter, and PTFE membrane filter media for a variety of conditions prerequisite for functional excellent filter material. Electrostatic precipitator Bag sewing technology have made great, some dust collector manufacturers has reached the level of foreign sewing bag.

Rotary cleaning bag filter working principle

The rim tangent direction of dusty gas from the air intake into the dust, the air in the lower part of the cylindrical segment rotation; under the action of centrifugal force and gravity, the larger particle size of dust separation along the cylinder wall down into the ash bucket. The finer dust rises together with the flow, radially arranged trapezoidal bag filter dust retention in the outside of the bag; purge gas empty filter bags from the bag sub catchy enter the net chamber, discharged from the trachea. Resistance left in the bag child outside of the dust layer thickening, the resistance reaches the set value, automatically starts reverse air fan with sufficient momentum hair blown into the bag by the the cantilever wind pipe through the nozzle, causing the bag vibration shaking off the cake; when the bag drag down to the lower limit, reverse air fan automatically stop working. Followed by cycle, Precipitator, cleaning and dust collection. dust filter bags

(1) blowback fan. The blowback fan rotary cleaning bag filter equipment. The ventilator is commonly used reverse air fan; mainly using the technical characteristics of the low air volume, high wind pressure and compact, ideal for rotary cleaning reverse jet baghouse need. When a large coal-fired boiler flue gas desulphurization and dust removal applications long bag low pressure rotary cleaning dust collector, multi leaf blower.

The anti hair accounts for about 15% -20% of the air volume.

(2) air volume control valve. Air volume control valve installed in the the blowback fan outlet duct to adjust the size of the amount of anti-hair.

(3) anti-hair tube. Anti-hair the inhalation tube divided into segments and pressure segment. For atmospheric air blowback, not to set the suction pipe; households should be installed in the fan inlet additional safety net, to prevent rain, snow and foreign body aspiration fan.

(4) mechanical rotary device. Mechanical frame transfer device with a fork and turn the recommended application rotary mechanical rotary oil-bearing passed anti-hair nozzle. non woven fabric

(5) fan damping facilities. Import and export of blowback fan camp interface, set the damper fan base.

(6) program of cleaning control system. Science to save energy, the correct organization precipitator operation, to establish constant pressure cleaning system, is the main content of the the program cleaning system of the equipment; artificial tissue precipitators operate on their own.

Production and dust removal process needs, bag filter pressure loss can be scheduled for the 1200-1500Pa, the assessment to be run to determine the best value; regular cleaning can be implemented, according to the specific requirements set dust removal process.
