Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cleaning device for cooling tower fan blades. Background Art

[0002] When a cooling tower fan is used in a cooling tower, it generates flowing air through rotation. When the air flows through the packing layer, it comes into close contact with the water or coolant sprayed from the spray system, increasing the contact area and contact time between the air and the water, thereby accelerating the heat transfer and evaporation process. Through evaporation, the heat in the water is transferred to the air, thereby reducing the water temperature. In order to prevent the fan blades from being corroded by corrosive substances in the cooling tower during use, an anti-corrosion coating is generally applied to the blades. Before the anti-corrosion coating is sprayed on the blades, dust and other impurities on the blade surface need to be cleaned. Spraying water is generally used for cleaning. However, when the spray device cleans the blades, it can only clean one side of the blade in one cleaning process, resulting in low cleaning efficiency. Summary of the Invention
