Prepare magnesium hydrate electrolytic device with function is collected to chlorine

Technical Field

Background

In the chlor-alkali industry, the electrolyte containing Mg ions can cause serious blockage at the diaphragm of the cathode chamber, which affects the diaphragm efficiency, so that the Mg ions need to be removed before electrolysis. The reason why the membrane is clogged is that OH ions in the cathode chamber have a high concentration, Mg ions migrated from the anode chamber are rapidly combined, and MH has a very small solubility product, so that slurry-like MH is easily formed on the membrane to clog the membrane. However, if the nucleation of MH is controlled by controlling the concentration of OH ions in the solution, the problem can be solved, i.e. the concentration of Mg ions in the electrolyte is high at the beginning of electrolysis, OH ions are generated by cathodic electrolysis, and once OH ions are generated, they are rapidly combined with Mg ions to generate solid MH, and the product is easy to fall off and directly sink to the bottom, avoiding the occurrence of the situation of blocking the diaphragm.

In the test process, chlorine anions in the electrolyte lose electrons at the anode to generate chlorine, and the chlorine has strong oxidation performance and can cause environmental pollution when directly discharged into the air, thereby seriously threatening testers.
