SELF-CONTAINED ELECTROCHEMICAL MODULE Russian patent published in 2001 - IPC

FIELD: electrochemical processing of solutions. SUBSTANCE: invention can be utilized for electrolytic recovery of metals or for conducting oxidation-reduction processes. Self-contained electrochemical module to process solutions includes vertical cylindrical flow electrolyzer with solution pumping unit, anode and cathode made on basis of flow volume-porous electrode material and placed coaxially, anode and cathode current leads connected to D C power supply source, collecting chamber located in bottom part of electrolyzer and communicating with interelectrode space and indicator of ultimate filling of cathode with metal. Solution pumping unit is positioned in upper part of electrolyzer and provides for periodic reversible circulation of solution through cathode, collecting chamber is open towards interelectrode space and its outer side carries flow volume- porous material of cathode. Module is supplemented with comparison electrode connected to input of potentiostat which first output is connected to electric motor of solution pumping unit and which second output is connected to current leads of electrodes and to outer anode linked to inner anode. EFFECT: enhanced operational reliability and efficiency of electrochemical module. 2 cl, 1 dwg
