Problems solved by technology

[0002] In the current process design of traditional electrolyzers in the chlor-alkali industry, there is a hidden danger that when the electrolyzer system triggers interlock shutdown due to certain factors, if the liquid level of the anolyte high level tank is not enough to fill the anode chamber of the electrolyzer, it cannot catch up in time. If chlorine gas is used, the ionic membrane is easily corroded by chlorine gas, causing pinholes or large-scale damage. After parking, chlorine gas stays on the top of the anode chamber, and chlorine gas diffuses into the membrane...

Abstract

The invention relates to an electrolytic tank interlock shutdown system and method; the system comprises a control unit, a first height sensor, a second height sensor, an anolyte elevated tank, a catholyte elevated tank, an electrolytic tank and a pipeline system, and the anolyte elevated tank and the catholyte elevated tank are connected with the electrolytic tank through the pipeline system; thecontrol unit is respectively connected with the first height sensor and the second height sensor, and is used for determining whether to send out an alarm signal or an interlocking shutdown signal according to the current liquid level height of the anolyte elevated tank, the current liquid level height of the catholyte elevated tank and the low liquid level alarm value, and cutting off the powersupply of the electrolytic tank according to the interlocking shutdown signal. The invention ensures the safety of the electrolytic tank after the interlocking shutdown is triggered.

Description

technical field [0001] The invention relates to the field of electrolyzers, in particular to an electrolyzer interlock parking system and method. Background technique [0002] In the current process design of traditional electrolyzers in the chlor-alkali industry, there is a hidden danger that when the electrolyzer system triggers interlock shutdown due to certain factors, if the liquid level of the anolyte high level tank is not enough to fill the anode chamber of the electrolyzer, it cannot catch up in time. If chlorine gas is used, the ionic membrane is easily corroded by chlorine gas, causing pinholes or large-scale damage. After parking, chlorine gas stays on the top of the anode chamber, and chlorine gas diffuses into the membrane, causing membrane corrosion; another hidden danger is that the electrolyzer system is triggered by some factors. During interlock parking, if the liquid level of the catholyte high level tank is not enough to fill the cathode chamber of the e...
