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.
