Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for a cooling tower. Background Art

[0002] A cooling tower is a device for cooling a liquid. It usually consists of a tall tower-shaped structure, which contains packing materials and a spraying system inside. When the liquid passes through the packing materials in the tower, the cooling medium is sprayed onto the packing materials through the spraying system to conduct heat exchange with the hot medium. In this way, the temperature of the hot medium will decrease, achieving the purpose of cooling. Cooling towers are widely used in industrial production, especially in fields such as power plants, chemical plants, and refrigeration equipment.

[0003] When existing cooling towers are actually used, in order to improve the evaporation efficiency of the sprayed water in the cooling tower and thus achieve an efficient cooling effect, multiple nozzles are often used to discharge the cooling water, so that the cooling water can be discharged in an atomized state. However, during use, although a large number of nozzles are provided, the spraying inside the cooling tower cannot be very uniform, which will affect the cooling effect. Moreover, during the use process, some water vapor will form more water droplets on the inner wall of the cooling tower, which will also affect the flow of the liquid during use, thus affecting the use effect. Therefore, it is urgent to solve the above problems. Summary of the Utility Model

[0022] Refer to Figure 4 and Figure 5 , in a preferred embodiment, a plurality of scraping plates 43 slide on the inner wall of the cooling tower housing 1. The plurality of scraping plates 43 are respectively fixedly connected to the mutually remote ends of the plurality of support rods 4.
