Definition and anti-corrosion knowledge of cooling tower

　　        A cooling tower is a device in which water and air are in direct contact with each other for heat exchange. The mechanical cooling tower is mainly composed of fans, motors, fillers, water spreading systems, tower bodies, and water pans.The purpose of lowering the water temperature is achieved by the heat exchange between the air with a relatively low temperature and the water in the filler under the action of the fan.The structure and design conditions of the water tower are indicated in the product manual of each manufacturer. However, the unit of water ton we use for the circulating flow of the cooling tower is a commonly used unit in the world, and there should be a margin of about 20% in the selection.

Cooling towers are widely used in air conditioning refrigeration equipment and industrial production machines for heat dissipation and cooling, covering air-conditioning cooling, refrigeration, injection molding, tanning, foaming, power generation, steam turbines, aluminum profile processing, air compressors and other fields.The cooling tower industry divides cooling towers into airconditioning cooling towers and industrial cooling towers according to different application fields.

　　At present, industries with high anti-corrosion requirements for cooling towers generally choose FRP cooling towers, because the anti-corrosion ability, high temperature resistance and hardness made of FRP are relatively strong, and they are more suitable for long-term industrial use.Then, the welding place between the tube sheet and the tube can be coated with anti-rust paint for protection, and organic acid and bactericide are added to prevent corrosion.

　　Industrial cooling towers are products for lowering temperatures, and require larger water distribution spray systems and higher power air distribution systems in the layout of the tower body.Therefore, industrial cooling towers have larger volume, higher power, more consumables, and higher cost than air conditioning cooling towers.
