Type bag filter process-1

YCDM series of long bag low-pressure pulse bag type dust collector is in pulse injection (Jet Pulse) based on dust removal technology, to meet the large volume of flue gas and specially developed has ninety's international advanced level of pulse bag type dust collector. It can be used offline or online by bag of soot blowing mode, the cleaning effect is good, high dust removal efficiency, effluent concentration of the bottom, but also has the advantages of large air quantity, with reliable operation, maintenance, reasonable structure, running resistance bottom, covers an area of small, large volume of flue gas is widely used in metallurgy, iron and steel, electric power, chemical industry, machinery, building materials industries such as purification. There are upper case, a middle box body, an ash bucket, ash cleaning system, discharging system and control system. Duster adopts the intake chamber structure, smoke dust from the air inlet in the lower part of the box body through into ash hopper, part of the larger dust particles due to inertia collision, natural sedimentation functions directly into ash hopper, other dust particles with air to rise in each bag room, filtered by the filter bag, purified gas from the filter bag after bag, exhaust hole, air outlet of the induced draft fan is discharged into the atmosphere, the dust is blocked in the outer surface of the bag. With the filtration process continued, the outer surface of the filter bag dust accumulated with increasing, resulting in the precipitator itself also gradually increased resistance. When the resistance reaches a certain value, ash cleaning controller sends signals, poppet valve first make a bag of room to cut off filter air the room, and then open the electromagnetic pulse valve, compressed air, air bag pulse nozzle valve, a spraying pipe on a very short period of time (0.2- 0.3 seconds) injection to the filter bag. The high-speed expansion in the compressed air in the filter bag filter bag, to generate high-frequency vibration deformation, plus reverse airflow, the outer side of the filter bag attached dust cake deformation loss. In full consideration of the settling time of dust (dust off that can effectively into ash hopper), the bag chamber lift valve is opened, the filter bag filter bag chamber to restore state, and a bag of chamber into the ash, and so on until the last bag room cleaning end.
