What is the principle of circulating water electrolysis for descaling?
Through a certain descaling device, direct current is directly charged to the cooling circulating water. After electrolysis begins, heavy metal ions (including scale) in the water will adhere to the surface of the negative electrode in the electrolytic cell of the electrolysis descaling system, and the positive and negative electrodes will be reversed regularly. After switching, the scale attached to the negative electrode falls off and is discharged out of the circulating water system together with the drainage water. When used without reverse pole, a certain concentration of hydroxide ions and carbonate ions are generated in the cathode area, which promotes the combination of calcium and magnesium ions in the water with hydroxide ions and carbonate to form calcium hydroxide, magnesium hydroxide, Calcium carbonate and magnesium carbonate adhere to the cathode shell in large quantities to form a certain thickness of scale. Since the cathode produces a certain amount of hydrogen, the shell scale is basically loose and soft scale, so it can be cleaned using a physical scraper and high-pressure water flushing. In addition, according to the different hardness of water quality in different regions, the amount and shape of scale accumulated on the cathode cylinder are also slightly different.
At the same time, in the reaction area near the anode, under the action of the electric field, chlorine ions lose electrons and are converted into free chlorine, accompanied by the production of trace amounts of ozone, hydroxyl radicals and other strong oxidizing substances, which have an algae-killing effect.
This electrochemical treatment of circulating water can use an electrolytic descaling device, which is placed directly into the pool. It is easy to operate and unattended. It only needs to be cleaned regularly according to the scale accumulation situation.
