Abstract:
A filter assembly for holding a filter element within a hot gas cleanup system pressure vessel, said filter assembly comprising:(a) a tubular filter housing, said filter housing having a parallel top inner wall and bottom inner wall, where the top wall has a smaller inner diameter and where a joint is formed where the walls join, where the bottom wall ends in an integral outward-extending flange with holes therethrough, said walls defining an interior chamber; (b) a one piece, all metal, tubular fail-safe/regenerator device, having a parallel top wall and bottom outer wall, where the top wall has a smaller outer diameter and where a joint is formed where the walls join, said walls and joint mating with the inner walls and the joint of the filter housing, and where the bottom wall contains an integral outward-extending flange with holes therethrough which mate with the holes in the filter housing flange; (c) one essential sealing means consisting of one compliant gasket separate and apart from the filter housing and fail-safe/regenerator device, said compliant gasket positioned between mating joints of the filter housing and fail-safe/regenerator device, said gasket effective to provide a seal between the filter housing and the fail-safe/regenerator device; and (d) a porous filter element body attached at the bottom of the metal fail-safe/regenerator device.
