<p>A high temperature filter for separating finely divided solids from gas comprising an outer, refractory lined, and inner generally cylindrical vessels having an uncleaned gas inlet pipe, a clean air discharge pipe, and two gravel feed pipes, all extending into the inner vessel and a common solids outlet in the lower end of the outer vessel. Three elongated spaced apart louver assemblies are disposed within the inner vessel to provide therebetween spaces for this gravel. A gas inlet chamber is defined on one side of the inner vessel and is closed at its bottom end by a sealing closure plate, which extends from the air inlet side of the bottom end of the inner vessel to a track of a lower end of an outer louver assembly. Sealing and connecting of the gravel feed pipes and the gas discharge pipe, respectively, to the inner vessel and between both vessels, respectively, provide for thermally induced differential movement. The louver assemblies are supported by a track assembly connected to the inner walls of the inner vessel thereby permitting slidable movement of the louver assemblies frame. When coarse and fine gravel fill the spaces between the louver assembly, finely divided solids are removed from feed gas entering the unclear gas inlet pipe as this gas horizontally traverses through the coarse and then the fine gravel held between the spaces of the louver assemblies and is withdrawn from an open ended gas outlet chamber on the other side of the inner vessel.</p> |
