ELECTRIC DIALYZER Russian patent published in 1994 - IPC

FIELD: separation of chemical compositions. SUBSTANCE: electric dialyzer has bracket with two frames, which are interconnected by four rectangular rods, ion-selective membrane of first type, which is stretched in tape-type manner to form multiple Z-shaped link member on supporting plates, packs, each having two frames with feeders and flat ion-selective membrane of second type disposed between them, two covers with electrodes and two slabs with working medium supply and discharge channels. Packs containing frames with membranes are introduced into tape links from two opposite sides. Feeders are formed as trapezium-shaped depressions. Tubes are laid in depressions in fanlike manner and covered by plates, which completely overlap depressions and are positioned in flush with frame surfaces. Electric dialyzer has minimum of parts simple and adaptable for manufacture. Dialyzer is assembled by introducing one membrane formed as Z-shaped tape and inserting packs with membranes of second type into links. EFFECT: simplified construction and easy assembling, reliable pressurization with slight deformation of membranes and easy replacement of packs. 3 dwg
