ABSTRACT:
A filtering apparatus for separating particulates from a hot gas stream using hollow, tubular filter elements has a housing with a laterally extending support plate for the filter elements separating the housing into upper and lower sections. The tops of the filter elements are biased against the support plate and the bottoms thereof restrained from lateral movement by restraining rings. Blowback and purge gas systems provide for cleaning of the filter elements and maintenance of the blowback system clear of the solids or condensation products that might form during the separation. The apparatus is especially useful in filtering solids from a hot, corrosive gaseous stream, such as a zirconium tetrachloride process gas stream, where the gas stream contains gaseous constituents that are subject to condensation or solids formation during separation of the particulates and prior to discharge from the filtering apparatus.
