Asphalt mixing plant special pulse bag filter
Release Time:2023-09-07
sinosun special pulse bag filter (pulse dust collector) for asphalt mixing plant has the advantages of large air volume, high purification efficiency, small footprint, small filter bag wear, long service life, simple replacement of filter bags, and convenient maintenance. The dust removal adopts pulse type countercurrent back blowing dust removal, and its electrical control adopts a sequence controller, which has reliable performance and can be widely used in metallurgy, chemical industry, machinery, non-ferrous casting, mining, asphalt concrete industry, cement, electric power, carbon black, grain processing And other new equipment for the purification and recycling of normal temperature and high temperature dust-containing gas in industrial and mining enterprises.

Cleaning process of bag filter in asphalt concrete mixing plant:
After the large particle dust in the dusty gas is collected by the primary dust collector, under the action of the induced draft fan, the airflow containing small particles enters the secondary bag filter for dust removal. The dust-laden gas enters the bag filter from the air inlet, and is filtered by the outer surface of the filter bag. The purified gas flows from the inside of the filter bag to the upper chambers, and is discharged from the air outlet through the long venturi tube. When the dust adsorbed on the outer surface of the filter bag reaches a certain value, it is controlled by the program to perform pulse injection at regular intervals, that is, when the high-pressure air is sprayed to the long venturi tube, the purified gas is blown back into the filter bag to form The large pressure difference sweeps the dust down to achieve the purpose of dust removal, and keeps the resistance of the entire equipment and system stable. The dust blown back falls to the bottom of the lower box and is discharged and recovered by the screw conveyor.
