Cooling tower definition and anti-corrosion knowledge

The cooling tower is a device in which water and air are in direct contact for heat exchange.Mechanical cooling tower is mainly composed of fan, motor, infill, watering system, tower body, water tray, etc.The purpose is to reduce the water temperature by mainly exchanging heat between the air having a relatively low temperature under the action of the fan and the water in the filler.The structure and design conditions of the water tower are indicated in the product manual of each manufacturer. The water ton used in the circulation flow of the cooling tower is the most commonly used unit in the world, we will have a margin of about 20% in the selection.

Cooling towers are widely used in air conditioning and refrigeration equipment and industrial production machines for cooling and cooling, ranging from air conditioning cooling, freezing, injection molding, tanning, foaming, power generation, steam turbines, aluminum profile processing, air compressors and etc.The cooling tower industry divides cooling towers into air-conditioning cooling towers and industrial cooling towers depending on the application.

At present, the industries with high anti-corrosion requirements for cooling towers generally choose FRP cooling towers because of the strong anti-corrosion ability, high temperature resistance and hardness of FRP, which is more suitable for industrial long-term use.Then, the joint between the tube sheet and the tube can be protected by anti-rust paint, and organic acid and fungicide are added to prevent corrosion.

Industrial cooling towers are high temperature drop products that require a larger water spray system and a higher power distribution system in the tower layout.Therefore, industrial cooling towers are larger, more powerful, more consumable, and cost more than air-conditioning cooling towers.
