[0040] The working principle of the energy-saving and emission-reducing cooling water tower is as follows:

[0041] In use, the staff sends the cooling water with waste heat into the spraying pipe 6 through the water pump, and then discharges the cooling water into the tower body 1 through the spraying port of the spraying pipe 6, so that the water is uniformly sprayed on the filler plate in the tower body 1 and forms a water film, then the staff starts the flow guide fan 402, under the flow guiding action of the flow guide fan 402, the outside air enters the tower body 1 through the air inlet groove 2 and exchanges heat with the water, so that the evaporation takes away the heat, after the water and the air exchange heat, the humid air generated by evaporation enters the second straight pipe 504 through the horn pipe 505 under the flow guiding action of the flow guide fan 402, then the humid air in the second straight pipe 504 enters the drying cylinder 503 and is dried, the dried air enters the connecting pipe 501 through the first straight pipe 502, and finally is discharged into the tower body 1, and cooperates with the outside air to exchange heat with the water in the tower body 1, by increasing the air discharge amount of the dried air, the heat exchange efficiency is improved, the humid air is prevented from being discharged to the outside, and the air energy is utilized, so that the energy-saving and emission-reducing purposes are achieved.
