ABSTRACT:
A dust collector has a dirty air chamber arranged to receive a flow of dirty air containing suspended solid particulate material, a clean air chamber communicating with exhaust, and a plurality of filter bags arranged to have their interior surfaces communicate with the dirty air chamber and operative to separate solid particulate material from cleaned gas passing therethrough. The improvement includes an elongated venturi-like member arranged to service a number of such filter bags, and a conduit arranged to deliver high energy pulses of reverse air through the venturi-like member countercurrent to the normal flow of dirty gas therethrough. Such pulses of reverse air momentarily create a reduced pressure within the serviced filter bags, and induce cleaned gas to flow back through the serviced filter bags to dislodge and remove accumulated solid particulate material from the interior surfaces of such bags.
