Abstract
A filtering apparatus for separating particulate matter from a gas stream. The filtering apparatus has a pressure vessel defining an interior chamber having a dirty gas inlet opening and a clean gas exit opening. A tubesheet is coupled within the pressure vessel thereby dividing said pressure vessel into a dirty gas side and a clean gas side. A support pipe for supporting a plenum chamber within the pressure vessel dirty gas side is securely coupled with the tubesheet. The plenum chamber for supporting a plurality of filter elements is coupled to the support pipe. The plenum chamber has a side wall having at least one dirty gas port and clean gas exit formed therein. The side wall further defines a clean gas chamber. A plurality of filter element guides are securely coupled within the clean gas chamber for supporting at least one filter element and preventing filter elements from moving laterally. A removable dirty gas port coupler for providing a particulate barrier seal between the dirty gas port and the plenum clean gas chamber is provided. A filter element support plate for supporting a filter element within the clean gas chamber is securely coupled adjacent the dirty gas port.…
