Chromium Salt Electrolyzer is composed of a tank, anode and cathode, most of which are separated by a diaphragm from the anode chamber and the cathode chamber.

Chromium Salt Electrolyzer is composed of a tank, anode and cathode, most of which are separated by a diaphragm from the anode chamber and the cathode chamber. The following Rongtai electrochemical equipment specifically introduces the main functions of the electrolytic cell.

How does Chromium Salt Electrolyzer work?

When direct current passes through the Chromium Salt Electrolyzer, oxidation reaction occurs at the interface between the anode and the solution, and reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. The distance between the anode and the cathode is one of the important factors affecting the voltage of the electrolytic cell. , Especially when working with high current, this voltage loss is more serious. Modern electrolyzers use various measures to reduce the electrode spacing, such as the use of diffusion anodes and modified membranes to make the structure of the electrolytic cell with zero electrode spacing.

The residence time of the electrolyte in the Chromium Salt Electrolyzer not only affects the production capacity of the equipment, but also affects the current efficiency of the electrolysis process in some cases, such as the electrolysis process of sodium chlorate. Since the chemical reaction between the intermediate product hypochlorous acid (Hclo) and hypochlorite ions (ClO3) is very slow, if it stays in the electrolytic cell for a long time, it will not only reduce the utilization rate of the electrolytic cell, but also the hypochlorite ions will be The anode surface is oxidized, or the current efficiency on the cathode surface is reduced. Therefore, modern electrolytic cell design strives to reduce the volume, so that the electrolyte flows quickly along the electrode.
