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.

Abstract: One aspect of the invention is directed to a filter assembly for use in a baghouse having a tubesheet with a plurality of thimbles each having a beaded portion. The filter assembly comprises a cylindrical filter bag having an axial end portion formed into a cuff. The cuff of the filter bag is adapted to be positioned within the thimble. The filter assembly also includes mounting structure adapted to be located within the cuff of the filter bag to mount the filter bag relative to a respective thimble of the tubesheet. The mounting structure comprises an annular gasket. The gasket includes a bead portion. The mounting structure also includes a resilient snapband for exerting a force to expand the gasket outward and seat the bead portion of the gasket within a beaded portion of the thimble to form a seal.
