What are the causes of corrosion in cooling towers, and how can corrosion problems be solved through anti-corrosion construction of cooling towers?
Firstly, let's understand the working principle of the cooling tower. The circulating coolant in the operation of the cooling tower is completed by water, and its main purpose is to reduce the water temperature and balance the water temperature. When the internal system of the cooling tower operates, the water temperature will continue to rise, and the cooling system will absorb and discharge the internal heat into the atmosphere to reduce the water temperature;
Its cooling effect is to use the cold and heat exchange after the water and air flow contact to generate steam, and the steam volatilization takes away the heat to achieve evaporation and heat dissipation, so as to reduce the water temperature and ensure the normal operation of the system.
What are the reasons for corrosion in the cooling tower? Firstly, the materials used in the cooling tower are mainly carbon steel, stainless steel, and copper. When carbon steel tube sheets are used as anti-corrosion for the cooling tower, corrosion leaks often occur at the welds between the tube sheets and the tubes, causing leakage into the cooling water system and causing environmental pollution. Because Shielded metal arc welding is mainly used in the manufacturing of the cooling tower, the gap and weld shape during welding will have different degrees of defects, such as dents, pores or welding slag. When some pipe fittings are in contact with the cooling water, impurities, microorganisms and salts in the industrial water will cause different degrees of corrosion to the weld and defects, because when using industrial water, whether it is fresh water or sea water, There will be various ions and dissolved oxygen, among which changes in the concentration of chloride ions and oxygen will cause varying degrees of corrosion to metals. In order to prevent the cooling tower from reducing work efficiency and posing varying degrees of safety hazards due to corrosion, the solution to this corrosion problem is to do a good job in the anti-corrosion work of the cooling tower..
