Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a circulating cooling water high-efficiency temperature reduction and anti-blocking device. Background Art

[0002] Cooling towers are structures used to cool water. They are commonly found in power plants, chemical plants, cement plants, and other factories that require a large amount of water temperature control. The stable operation of the cooling tower is the basis for the stable operation of the entire circulating water device. The circulating water with a higher temperature is evenly sprayed onto the filler through the spray pipe in the cooling tower. The wind blowing in forms convection with the water sprinkled from above. The water vapor evaporated by the circulating water is condensed by the condensation module composed of a fan and a heat exchanger. After the circulating water is distributed through the filler, it directly contacts the atmosphere for heat exchange and cooling, and then flows to the cooling tower pool.

[0003] When the cooling tower is used in winter in high-latitude areas, the water that seeps downward through the filler gathers in the cooling tower pool. Due to the cooling treatment of the water cup, the volume of cooling water after cooling freezes, causing the water outlet to be blocked, affecting the output of cooling water. For this reason, we propose a circulating cooling water high-efficiency cooling and anti-blocking device to solve the existing problem. Utility Model Content
