Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell devices, in particular to an ion membrane electrolytic cell performance detection device. Background Art

[0002] Currently, there are three electrolysis processes: the ion exchange membrane process, the diaphragm process, and the mercury process. With increasing attention to environmental issues, the ion exchange membrane process has replaced the latter two processes. Chlor-alkali plants typically use electrolytic cells composed of many unit cells. For example, in a bipolar device, when current is connected, each unit cell produces an electrolytic reaction. To control energy consumption and maximize production, it is desirable to maintain and improve electrolytic cell performance. Therefore, monitoring the electrolytic cell unit voltage, consisting of the anode electrolysis potential and the cathode electrolysis potential, is of paramount importance.

[0003] Document 201820198964.5 (A Performance Testing System for Ion-Exchange Membrane Electrolyzers) describes a method for measuring the electrolytic cell voltage and correlating it with relevant process parameters. The measured cell voltage is then compared with the calculated values ​​under different operating conditions. This comparison allows the operating status of the ion-exchange membrane electrolyzer system to be evaluated. This utility model not only implements an automatic safety interlock for the electrolytic cell system but also predicts future performance curves by evaluating current cell performance. However, in actual use, the structure described in the document suffers from the problem that if the fuse blows due to excessive current, even after restoring the cell voltage via a remote terminal, the fuse must be replaced promptly for the testing system to resume operation. Given the high voltage in the electrolytic cell, replacing the fuse while the cell is operating can be dangerous. Therefore, we have introduced a new performance testing device for ion-exchange membrane electrolyzers. Utility Model Content
