Description
Technical Field

Background
The cooling tower is an evaporation heat-dissipating device which utilizes water to exchange cold and heat after being in flowing contact with air so as to reduce the water temperature, and the cooling tower generates 'white fog' after the hot and humid saturated air flowing out of the air outlet cylinder is contacted with external cold air in the actual operation process, especially in cold weather, thereby causing inconvenience to surrounding traffic while affecting the environment. For this reason, manufacturers of cooling towers today have made it an important subject of investigation how to eliminate white mist. At present, an air mixer is added in the tower, when the cooling tower operates, rising hot and humid saturated air and dry and cold air transversely entering the tower are mixed under the action of the air mixer, and moisture in the hot and humid air can be condensed after heat exchange, so that the moisture content of the hot and humid air is reduced, and the 'white fog' generated after the tower outlet air flow contacts with the cold air outside the tower is reduced.
