Dust collector filter bag bag filter mechanism

Diffusion effect: less than 0.2 m of dust particles and gas molecules collide with each other, resulting in irregular movement, irregular movement, a portion of the dust particles are fibers or dust layer retention, a phenomenon known as diffusion effect.
The inertia efficiency: if the large mass of dust particles known as inertial effects, when the gas flows through the fibrous layer was stopped Mechanism. Due to inertia caused by the trapping efficiency is proportional to the size of the dust particles. The density of the dust particles and the velocity of the airflow and inversely proportional to the diameter of the fiber.
Direct interception: When the extension of dust particles airflow line directly to the fiber collecting movement, because the airflow line interval in the range of the radius of the dust particles from the surface of the fiber, dust particles and fibers exposure and is captured, this catch set mechanism is called direct interception.
Electrostatic attraction: Flushing fiber fishing collective friction role in bringing fiber charged. Some dust particles in motion will bring the charge. Such as fiber impregnated with resin, charge role will strengthen, the electrostatic field is applied in the outside world is not catching collective conductive ionized gas molecules after radioactive irradiation, the settlement of the charged particles and other phenomena, this charge will decrease slowly. When no external electric field, 3 (1) particles charged catch collective neutral, then catch collective reverse induced charge, the electrostatic adsorption force (2) harvesting the collective charged particles neutral, the particles only reverse induced charge attraction (3) both charged, according to the charge pairing may be absorbed, there may be repulsive forces.water filter bags
Sieve effect: the gap between the filter or dust on the filter, the gap between the more dust particles hour is conducive to screening retention, that is, the screening effect. Obviously, the larger the dust particles, the smaller the fiber voids, the greater the probability is sieved. Under normal circumstances, the new clean bag screening effect is not strong. When the dust large settlement when the dust layer is formed in the surface of the bag, screening greatly enhanced, and separation and dust trapping efficiency progress.
6 capture unsteady filter: The Hartcourt Guthrie bag filter in time series can be divided into two phases, the stable filter and non-stability filtration stage. In stable filtration stages, assuming ignore the deposition of particles generated on the bag changes in the structure, the particles contact with the fibers are trapped, and do not consider the filtering mechanism of correction, therefore, the trapping efficiency from the filter time. With the filtration time increases, the particle lead to unsteady filter stage generates gradually formed in the surface of the fiber the cloth change of porosity and particle formation chained deposition is conducive to the progress of the fiber collecting ability, lead time and particle trapping efficiency with filter deposition amount increases. Clean state, the single fiber collection efficiency is defined as the particle limit trajectory at the inlet height and the ratio of the fiber diameter, to produce a more significant change in the actual filtering process, with the time increases, the shape and size of the fibers. . In the state of non-stable filter, according to the law of conservation of mass, the quality of the flow into the micro unit less to the quality of the outflow micro unit that increase the quality of the infinitesimal body.liquid filter bags
Filter cleaning regeneration: regeneration of filter cleaning product for the filtration process dust layer on the surface of the bag attached to the broken ring and part of the cleanup on the filter, thereby restoring the normal filtering function of the filter. The cleaning may be periodic, or may be carried out continuously. The cleaning effect is good or bad filter and dust properties, filter conditions, blowback conditions, and many other conditions. The filter cleaning renewable continuous work, the same filter is as important as the process and links.
