Abstract
A cleaning system for dislodging dust from the filter bags of a dust filter having dirty and clean air plenums separated by a tube sheet. The tube sheet is divided into segments each having filter bag openings arranged in the same pattern. An air accumulator tank which continuously receives compressed air is rotated in the clean air plenum with a connected distribution arm which applies air pulses to the filter bags through discharge nozzles arranged in the same pattern as the filter bag openings. A position sensor allows cleaning air in the tank to be applied to the distribution arm only when the arm is aligned above a segment with all nozzles centered on the filter bags. A quick acting diaphragm valve is combined with the air tank to control air flow into the distribution arm at a location adjacent to the arm to minimize the response time.
