technical field

The utility model relates to a water-saving and fog-eliminating cooling tower.

Background technique

A traditional cooling tower generally includes a tower body, an exhaust device, a packing layer installed in the tower body, and a spray device. When in use, the hot water sprayed by the spraying device sprays into the packing layer from top to bottom, and the dry and cold air from the outside enters the packing from bottom to top, and the hot water and cold air exchange heat in the packing layer, so that the hot water The temperature is cooled down, while the air is heated and humidified, and the high-temperature and high-humidity air is discharged from the tower through the air outlet. However, in winter, due to the high water vapor content of the high-temperature and high-humidity air, it is cooled by the external cold air when it is discharged out of the tower, and condenses to produce a lot of water droplets, which in turn produces white mist. The white mist fell on the ground and caused the road around the cooling tower to be slippery, which affected the normal inspection of the staff. Moreover, a large amount of water is lost by evaporation, which is far from meeting industrial needs.
