ABSTRACT:
A filter bag structure for use in a baghouse that has a tubesheet with a plurality of openings. The filter bag structure includes a substantially cylindrical filter bag having an axial end portion formed into a cuff. The filter bag has filtration media of a substantially electrically non-conductive material. The cuff of the filter bag is to be positioned adjacent an opening and mounted to structure of the tubesheet. An electrically conductive ground wire extends along a portion of the filter bag and has a portion to contact the tubesheet. An electrically conductive anti-collapse ring extends around another portion of the filter bag. An electrically conductive cover secures the anti-collapse ring to the filter bag and provides electrical conductivity between the ground wire and anti-collapse ring.
