Description

Technical Field

[0001] The utility model relates to the technical field of closed cooling towers, in particular to a closed cooling tower. Background Art

[0002] Closed cooling tower, also known as closed cooling tower for short, places a tubular heat exchanger inside the tower, and ensures the cooling effect through the heat exchange between circulating air, spray water and circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted, which well protects the efficient operation of the main equipment and increases the service life. When the outside temperature is low, the spray water system can be stopped to save water. With the implementation of the national energy conservation and emission reduction policy and the increasing scarcity of water resources, closed cooling towers have been widely used in metallurgy, aviation, electric power, chemical industry, machinery, petroleum, food, plastics, rubber and other industries in recent years.
