ABSTRACT:
Apparatus for removing dust from a gas stream comprises a duct with an inlet at its top, a hopper spaced beneath the inlet, and a lateral outlet at a level between inlet and hopper. Gas flowing from inlet to outlet must traverse a vertically extending filter comprising elongated parallel electrodes laterally spaced from one another at small intervals. Each electrode is connected with a terminal of an alternating voltage source different from that with which its adjacent electrodes are connected. The constantly varying alternating electric fields at the filter repel particles so that they fall into the hopper.
