MEMBRANE-TYPE APPARATUS Russian patent published in 1995 - IPC

FIELD: membrane separation apparatuses. SUBSTANCE: membrane-type apparatus has housing, covers and blocks of cylindrical tubular members whose ends are hermetically sealed in cylindrical tubular grates. Housing has rectangular section and is provided with vertical walls dividing it into working chambers. Each block of tubular membrane members is provided with end covers with branch pipes and annular sealing members as well as with supporting rings with inner conical surface. Supporting rings are arranged in pairs in axially aligned relation on outer sides of two opposite housing walls and rigidly secured on them. Tubular membrane member blocks are staggered in working chambers so that annular sealing members are positioned between outer cylindrical surface of tubular grates and inner conical surface of supporting rings. End covers are biased to annular sealing members. EFFECT: increased efficiency and simplified construction of apparatus. 1 dwg
