Abstract

A fabric filter is disclosed including a clean air plenum and a dirty gas side separated by a cell plate which includes concentric rings of holes providing gas communication between the two sections. The holes have connected thereto respective filter media bags for collecting contamination held in suspension in the gas being filtered. In order to clean the filter bags there is provided a back flushing gas pulse generator which includes a main diaphragm valve in direct communication with a hollow rotatable shaft which leads to a gas pulse distributor having arms which sweep across the clean air plenum side of the cell plate. The arms of the high volume low pressure pulse jet manifold have apertures aligned with the respective holes of the cell plate so as to inject into the filter media bags a pulse of clean gas in a reversed direction so as to shake out any contaminants that have been collected in the bags. An inductor is fitted to some or all of the apertures on the manifold arm as required to enhance a flow of back-flush air into each hole in the cell plate. The inductor includes a central passage and a venturi passage to increase air flow.
