ABSTRACT:
The present invention shows a cleaning system for dislodging the collected dust from filter media in a low pressure high capacity gas stream filter. In the preferred embodiment, pressurized gas from an external tank is ducted through a revolving arm which stretches radially across a pie-shaped segment of a tube sheet separating a clean gas plenum from a dirty gas plenum in a bag collection gas filtration system. The ducted gas is intermittently discharged from the rotating arm through multiple orifices into a venturi contained within the openings in the tube sheet as these orifices are above the individual filter elements.
