DIAPHRAGM flat-CHAMBER SEPARATING APPARATUS Russian patent published in 1994 - IPC

FIELD: chemical engineering; separation of mixtures. SUBSTANCE: diaphragm separating apparatus incorporates housing, turbulator, drain support which carries on its surface base and semi-permeable diaphragm, and manifolds to admit mixture to be separated and discharge filtrate and concentrate. Drain support is made detachable in the form of stack of plates or reeled strips whose contact surfaces carry parallel protrusions or depressions which form through passages to tap off filtrate. Protrusions and depressions made in adjacent contact surfaces are predominantly inclined at opposite angles of tilt relative to base of plates or that of drain support strips. EFFECT: more sophisticated design and more effective separation of mixtures. 3 cl, 2 dwg
