The circulating cooling water contains certain scaling ions, and after a certain circulation multiple, the scaling ions are concentrated, so that the scaling tendency is strong, and slightly soluble salt is generated. These salts are easily supersaturated and crystallize out of the water, especially when the water flow rate is low or the heat transfer surface is rough, and these crystallized deposits deposit on the heat transfer surface to form scale.
The scale can block the heat transfer of the cooling water and influence the cooling effect. Meanwhile, corrosion may occur, which affects the service life of the equipment. The scale adheres to the cooling pipe, which causes problems such as a decrease in the amount of circulating water in the pipe and clogging of the heat exchange pipe. These problems can threaten and destroy the safe production of the plant, increase the operation and equipment maintenance cost and cause great economic loss to the plant. An economical and practical circulating cooling water treatment scheme must be selected for the purpose. At present, the scaling tendency of the water body is generally reduced by adding a scale inhibitor or a side-filtering scaling system. However, adding a scale inhibitor or a side-filtering scale removal system leads to increased production cost and a complex process, and an efficient and continuous scale removal mode cannot be achieved.

Meanwhile, electrochemical reaction occurs on the negative plate 3, water is ionized to generate hydroxyl negative ions, and slightly soluble salts are generated with positive ions such as calcium, magnesium and the like. When these salts are supersaturated in the circulating cooling water, crystals are precipitated to form scale, and the scale adheres to the negative electrode plate 3.
