Abstract

The invention relates to a pressure stabilizing device for an ion exchange membrane electrolytic cell, and in particular relates to an electrolytic cell pressure stabilizing device, aiming at providing the electrolytic cell pressure stabilizing device capable of providing accurate and stable pressure difference during pressurization or depressurization of the ion exchange membrane electrolytic cell. The electrolytic cell pressure stabilizing device comprises a cathode pool and an anode pool, as well as a cathode inserting pipe inserted into the cathode pool, and an anode inserting pipe inserted into the anode pool, wherein the cathode pool is communicated with the anode pool by a connecting pipe; height difference exits between the plane on which an outlet of the cathode inserting pipe is positioned and the plane on which an outlet of the anode inserting pipe is positioned; the top of the cathode pool is provided with a cathode side connecting pipe and a hydrogen recovery pipe; the top of the anode pool is provided with an anode side connecting pipe and a chlorine recovery pipe. The formed pressure difference does not exceed a limit value of an ion exchange membrane. The pressure stabilizing device is used for providing stable and accurate pressure difference for the ion exchange membrane electrolytic cell.

Description

technical field [0001] The invention relates to a pressure stabilizing device for an ion membrane electrolytic cell, in particular to a voltage stabilizing device for an electrolytic cell. Background technique [0002] Ion-exchange membrane is the core of the ion-exchange membrane alkali-making process, and it is expensive and easily damaged. The ionic membrane has very high requirements for process stability. In daily operation, the pressure difference on both sides of the ionic membrane must be kept within a certain pressure range (generally 4.5KPa). Especially in the process of increasing the pressure and reducing the pressure, the difference in the pressure on both sides of the ion membrane will cause damage to the ion membrane. The damage of the ion membrane mainly refers to the occurrence of a large number of leakage points on the ion membrane. The existing operation (for a pressure difference of 4.5KPa) is to artificially pressurize both sides of the ionic membrane t...
