Description

Technical Field

[0001] The utility model relates to the technical field of electrochemical water treatment, in particular to an electrochemical descaling and algae-killing device for cooling circulating water. Background Art

[0002] When circulating cooling water flows through the heat exchanger for heat dissipation, the temperature will rise due to the heating of the heat source, and the water will evaporate in the cooling tower, causing the impurities in the water to concentrate, thereby reducing the water quality. The carbon dioxide in the water will be decomposed and dissipated, increasing the tendency of calcium carbonate in the water to scale and precipitate on the heat exchange surface, resulting in an increase in the scaling trend.

[0003] When water comes into contact with air in the cooling tower, the dissolved oxygen in the water becomes saturated, which leads to electrochemical corrosion of the metal (oxidative corrosion). When hot water and air produce convection during the cooling process, a large amount of dust, sediment, microorganisms, etc. in the air are inhaled, which increases the sludge in the system. Under suitable conditions of sunlight, temperature and oxygen, bacteria and algae will grow in the cooling tower. After bacteria and algae grow in the cooling tower, scale is easily generated and deposited on the surface of the heat exchanger, affecting heat transfer, and easily causing equipment corrosion, which directly endangers the service life and heat exchange effect of the system. Therefore, it is necessary to descale the scale. Utility Model Content
