ABSTRACT:
A self cleaning industrial dust filter includes a housing divided by a tube sheet into an upper clean air chamber and a lower dirty air chamber. Pleated fiber cartridge type filters are supported in the lower chamber from the tube sheet and the interior of the filters communicate with the clean air chamber through openings in the tube sheet, one for each filter. The lower chamber is formed as a plurality of panel venturis which converge downwardly from the lower end of the filters to a narrow throat. A clean air outlet connects with the upper chamber and a dirty air inlet with the lower. Downwardly directed jet nozzles are positioned in each venturi to induce reverse flow through the associated filters, remove accumulated particulates and conduct them to a take out at the base of the lower chamber.
