Abstract:
A filter assembly for use in a baghouse and adapted to hang in a substantially vertical direction, the baghouse being divided into first and second plenums by a substantially planar tubesheet portion with a plurality of openings, the first plenum having a first dimension taken normal to the planar portion of the tubesheet, the second plenum having a second dimension taken normal to the planar portion of the tubesheet and being greater than the first dimension, said filter assembly comprising:a first filter portion including a first attachment at a first end adapted to mount to the tubesheet adjacent an opening through the tubesheet to support at least a portion of said first filter portion in the second plenum and to permit fluid communication between said first filter portion and the first plenum, a tubular member fixed to an extending from said first attachment, a pleated filter element disposed adjacent to said tubular member for support, and a second attachment fixed to said tubular member at a second end of said first filter portion, said second attachment defining an opening through which fluid may flow, said tubular member fixed to said first and second attachments with a strength sufficient to support the weight of at least one other filter portion;a second filter portion including a third attachment at a first end and which said third attachment defines an opening through which fluid may flow, a tubular member fixed to and extending from said third attachment, a pleated filter element disposed adjacent to said tubular member for support, and a plate at a second end of said second filter portion to define a closed end of said second filter portion; anda clamping mechanism to sealingly connect said second attachment of said first filter portion with said third attachment of said second filter portion and permit fluid communication between said first and second filter portions, said clamping mechanism having a strength sufficient to support the weight of at least one filter portion located on the side of said clamping mechanism opposite the first attachment of said first filter portion.
