ABSTRACT:
A system for cleaning dust collecting filter bags with pulsed air includes a plurality of rectangular channels positioned below a tube sheet supporting rows of filters. A short length of pipe connects the channels through the tube sheet to the top of a venturi within the open end of each filter bag. A source of compressed air periodically supplies pulses of air through the channels and openings in the pipes to force air through the center of the venturis and bags in a reverse direction to clean the filters. The channels are preferably positioned between pairs of filters to clean two rows at the same time for greater efficiency, while providing permanent added structural support for the tube sheet.
