Background
The closed cooling tower is a novel cooling device which can reduce the temperature of cooling water and keep the water quality pure, and has the characteristics of multiple functions, strong adaptability to the environment, capability of cooling high-temperature water, safety, fire prevention and the like. In low-temperature weather with high humidity, 'white fog' is easy to appear at the air outlet of the cooling tower. The reason for this is that the fresh air introduced into the cooling tower is directly contacted with the packing and the cooling water in the cooling tower, and through heat and humidity exchange, the fresh air is heated and humidified and finally discharged from the outlet port in the form of high temperature and high humidity air, thereby forming white mist. The air near the air outlet of the air duct of the cooling tower is condensed into a plurality of fine boiled water after contacting with air with lower outside temperature, so as to form 'white fog'. When the white fog phenomenon generally occurs in a range of a few meters above an outlet of a cooling tower, the cooling tower generates white fog, and floating water exists in the cooling tower, namely cooling water is lost in the heat exchange process; the generated white fog can affect the visual effect of buildings and surrounding environment, and the white fog can also affect the sight of surrounding residents.
