REVERSE CURRENT PREVENTION METHOD FOR ION EXCHANGE MEMBRANE ELECTROLYTIC CELL

摘要

PROBLEM TO BE SOLVED: To provide a reverse current prevention method for an ion exchange membrane electrolytic cell which can prevent a reverse current generated after the operation stop of the ion exchange membrane electrolytic cell.;SOLUTION: A reverse current prevention method is for an ion exchange membrane electrolytic cell 100 which includes an anode chamber 107 accommodating an anode, a cathode chamber 110 accommodating a cathode, an anolyte supplying manifold 121 supplying an anolyte to the anode chamber 107, and a catholyte supplying manifold 124 supplying a catholyte to the cathode chamber 110. After the operation stop of the ion exchange membrane electrolytic cell 100, a low conductive material having a lower electrical conductivity than that of the anolyte or catholyte is poured into at least one of an anolyte supply pipe 127 supplying the anolyte from an anolyte tank 123 to the anolyte supplying manifold 121 and a catholyte supply pipe 128 supplying the catholyte from a catholyte tank 123 to the catholyte supplying manifold 124.;COPYRIGHT: (C)2014,JPO&INPIT
