Description

technical field [0001] The invention relates to the field of chemical production equipment, in particular to an anti-clogging high-efficiency electrolysis device used in chemical production. Background technique [0002] The electrolytic cell is composed of a cell body, a cathode and an anode, most of which are separated by a diaphragm from the anode chamber to the cathode chamber. According to the different electrolytes, it is divided into three types: aqueous solution electrolyzer, molten salt electrolyzer and non-aqueous solution electrolyzer. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the cross section between the cathode and the solution to produce the desired product. [0003] It does not prevent the mixing of the cathode and anode products and avoid possible harmful reactions. In the electrolytic cell, the cathode and anode chambers are ...

AI Technical Summary

Problems solved by technology

[0003] It does not prevent the mixing of the cathode and anode products and avoid possible harmful reactions. In the electrolytic cell, the cathode and anode chambers are basically separated by a diaphragm. However, when electrolyzing saline solutions such as sodium chloride, calcium , magnesium ions and other impurities, these impurities are easy to form hydroxide precipitates in the diaphragm, reduce the permeability of the brine solution, and lead to a decrease in the production efficiency of the electrolytic cell. Not only that, as the electrolysis time increases, the sodium chloride brine Chloride ions lose electrons and react to generate chlorine gas, which gradually reduces the concentration of chloride ions in the brine, thereby reducing the production efficiency of the electrolyzer, thus reducing the practicability of the existing electrolyzer
