Water-saving environment-friendly fog-dissipation-type cooling tower and working method thereof

[0038] see figure 1 , figure 1It is a structural schematic diagram of an optimal embodiment of a water-saving, environment-friendly and fog-eliminating cooling tower of the present invention; figure 1 As shown, the present invention provides a water-saving, environment-friendly and fog-eliminating cooling tower, comprising: a tower body 1, a water distribution system 2 installed at the inner bottom of the tower body 1, and an operation mode switch installed above the water distribution system 2 system 3, and a heat exchange device 4 installed above the operation mode switching system 3; the water distribution system 2 can generate saturated hot and humid air; the heat exchange device 4 includes several heat exchange groups 41 arranged horizontally, and the The heat exchange group 41 can be opened and closed to communicate with the outside of the tower body 1. Specifically, part of the heat exchange group 41 communicates with the outside of the tower body 1. This part is used to

[0055] On the basis of Embodiment 1, this Embodiment 2 also provides a working method of a water-saving, environment-friendly and fog-eliminating cooling tower. During normal operation, the heat exchange group 41 closes the communication with the outside of the tower body 1 , that is, no unsaturated dry and cold air enters the heat exchange group 41, and the operating mode switching system 3 can completely discharge saturated hot and humid air into the heat exchange group 41; during the defogging operation, the heat exchange group 41 is opened Communication with the outside of the tower body 1, the switching mechanism can prevent part of the saturated hot and humid air from entering the heat exchange group 41, that is, only part of the saturated hot and humid air can enter the heat exchange group 41, while the other part will pass into the heat exchange group 41. The unsaturated dry and cold air outside the tower body 1, the saturated hot and humid air exchanges heat with the unsa
