APPARATUS FOR ELECTRODIALYSIS AND SORPTION FOR PRODUCTION OF ULTRAPURE ALKALIS Russian patent published in 1997 - IPC

Abstract RU 2093251 C1

FIELD: chemical industry; may be used in production of caustic alkalis, in particular, potassium hydroxide. SUBSTANCE: apparatus has ion-exchange column filled with mixed layer of ionite and electrode chamber. Ionite layer is separated in column by receiving chamber made in the form of labyrinth and provided with valves of intake and discharge of purified solution. Apparatus cathode chamber has levelling vessel with gages of lower and upper levels of electrolytes. Each level gage is connected by control unit of shutoff valves. EFFECT: higher efficiency. 1 dwg
