The utility model belongs to the field of cooling tower water spraying technology, specifically refers to a demisting cooling tower water spraying device, which effectively solves the problem that the current cooling tower water spraying device is inconvenient to adjust the water mist spraying angle and is inconvenient to filter impurities in the water mist, and achieves the purpose of conveniently adjusting the water mist spraying angle and conveniently filtering impurities in the water mist by the demisting cooling tower water spraying device, and is a very practical demisting cooling tower water spraying device.

[0004] However, the position of the nozzle of the water spraying device is often relatively fixed, and the nozzle is not convenient to lift and lower. As a result, when the water spraying device is not needed for spraying water, the nozzle will be exposed to the outside for a long time. The nozzle and the inner wall of the installation box are not well matched, so that a large amount of dust adheres to the surface of the nozzle, causing the nozzle to be blocked, thereby reducing the water spraying effect of the demisting cooling tower.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a mist-eliminating cooling tower water spraying device is proposed. Utility Model Content

[0006] The utility model aims to provide a water spraying device for a mist-eliminating cooling tower, so as to solve the problem that the lifting and lowering of the spray head is not convenient and the water spraying effect of the mist-eliminating cooling tower is reduced in the above-mentioned background technology.
