Among them, tower top spray type has higher cooling efficiency, but is greatly affected by wind and environment;

[0003] Since the circulating water of the cooling tower in the prior art is in direct contact with the outside air, impurities such as dust and microorganisms in the environment can easily enter the spray water, causing the water quality to deteriorate. These impurities will form scale on the surface of the cooling tower coil, reducing the heat exchange effect and increasing the risk of equipment corrosion. In addition, as the water evaporates, the concentration of salt and other dissolved solids in the water gradually increases, causing serious scaling, which affects the use of the cooling tower.

At this time, stop applying pressure to the positioning plate 406, so that the spring 407 releases its elastic force to drive the positioning plate 406 to reset until it is inserted into the positioning slot 402, thereby completing the fixation of the brush roller 311.
