Rajdeep engg systems offers dust collection systems. Air along with dust particles under suction or pressure enters the lower portion. The air travels through the filter bag, which retains the dust particles on surface of the bag, and the clean air passes out through bags and plenum to the outlet of bag filter. Dust collected on the outside of the filter of the bag filter. To control the pressure differential across the bag filter, a sequential bag causes an increase in the pressure differential between dirty and clean air. Side timer actuates a series of normally closed pulse valves at preset intervals causing them to open. A momentary rush of high-pressure air [4-5 bar g] flows from the compressed air header to the blow tube and is expelled from the blow tube through nozzles at high velocity [primary air flow]. Air from each nozzle induces a secondary airflow. The combined effect of the primary and induced secondary air causes an instantaneous pressure rise on the clean side of the filter bags, causing a reverse flow air through filter bags, thus dislodging the dust particles held on the outer surface of the bags.
