Cross-flow type cooling tower capable of saving water and eliminating mist

Abstract

The invention discloses a cross-flow type cooling tower capable of saving water and eliminating mist. The cooling tower comprises a tower body, a water distributing system, a water collector used for collecting floating drops carried in airflow and a padding structure used for heat exchange. The water distributing system is provided with water distribution devices arranged on the top of the tower body, and the padding structure is arranged around the tower body to form the peripheral wall of the tower body. The padding structure comprises multiple first padding bodies and multiple second padding bodies, wherein cold airflow flows into the first padding bodies, and cooling water and the cold airflow flow into the second padding bodies. The first padding bodies and the second padding bodies are arranged in a closely staggered mode in the transverse direction. The first padding bodies are provided with multiple first sealed channels transversely extending from the outside of the tower body to the inside of the tower body, and the second padding bodies are provided with multiple second sealed channels extending from the top of the tower body to the bottom of the tower body. The top ends of the second sealed channels are communicated with the water distribution devices, and the water collector is arranged in the tower body. An exhaust outlet is formed in the top of the tower body, and an outlet of the water collector is communicated with the exhaust outlet. By means of the cross-flow type cooling tower, mist can be effectively reduced, and a water saving effect is achieved.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a water-saving and fog-eliminating cross-flow cooling tower. Background technique [0002] In the projects of established power plants, petrochemical, papermaking, metallurgy and other industries, most circulating cooling water systems adopt open systems, and the main equipment is traditional wet cooling towers. The make-up water of this type of circulating cooling water system accounts for more than 60% of the fresh water consumption of the whole plant. A large steel company, or a large chemical company such as 4 billion m 3 / a coal-to-natural gas project, the size of the circulating water cooling tower is about 200,000 m 3 / h, its replenishment amount is about 2%. During the normal operation of the project, the cooling tower emits about 150,000 tons of water vapor into the air every 2 days, forming fog. [0003] In a traditional cross-flow cooling tower, the water distribution system and ...

AI Technical Summary

Problems solved by technology

Therefore, during the operation of the cooling tower, a large amount of water is evaporated and consumed, and a large amount of fresh water needs to be continuously replenished, which consumes more water resources.
