ELECTRODIALYZER Russian patent published in 1996 - IPC

FIELD: electrochemical machining of liquids-electrolytes, in particular, electrodializing apparatuses, and can be used mainly for production of very concentrated brings. SUBSTANCE: electrodialyzer uses terminal electrodes, placed between which is a pack of anion-exchange and cation-exchange membranes and frame spacers, positioned between the clamping plates and fastened by clamping devices, sections of spacers, in which holes are made for inlet and outlet of solutions, are brought out beyond the limits of the membrane and made of two members containing grooves or supporting bulges of the ping-pong type, which are aligned at assembly forming closed ducts. Consumption of electric power for production of brines of concentration within 180 to 200 g/l makes up 33 to 35 W h/H equiv. EFFECT: enhanced reliability in operation. 5 dwg
