Fabric Bag Dust Collector
In the fabric bag dust collector, individual bags are supported by a metal cage inside the fabric bag which is fastened onto a cell plate at the top of the bag filter. Dirty gas enters from the bottom of the bag filter and flows from outside to inside the bags. The metal cage prevents the collapse of the bag filter.
Filter bags are cleaned by a short burst of compressed air injected through a common manifold over a row of filter bags. The compressed air is accelerated by a sand blasting nozzle mounted at the fabric bag dust top of the bag. Since the duration of the compressed-air burst is very short (0.1s), it behaves as a fast-moving air bubble, traveling the entire length of the filter bag and causing the bag surfaces to flex or move. This flexing or moving of the filter bags breaks the dust cake formed on them, and the layer of dust falls into a sand blasting hopper placed below the dust collector machine.

Fabric bag dust collector can work continuously and cleaned without any hurdle in the flow because the burst of compressed air is very small as compared with the total volume of dusty air through the fabric bag dust collector. Due to this continuous-cleaning feature, reverse-jet fabric bag dust collectors are usually not compartmentalized and even allow them to operate at higher air-to-cloth ratios.
This cleaning system works with the help of a digital sequential timer attached to the fabric bag filter. This timer signals the solenoid valve to inject the air into the blowpipe in the fabric bag so that the dust cake could be broken and collected in the storage hopper.
