Cooling device for main pipe of aeration tank

The utility model discloses a cooling device for a main pipe of an aeration tank, which comprises a spray nozzle frame, a plurality of groups of spray nozzles are arranged on the spray nozzle frame, and the spray nozzle frame is arranged above a pipeline. The aeration device has the advantages that the cold water spraying pipe is additionally arranged on the aeration main pipe to spray the aeration main pipe, so that the temperature of the aeration main pipe is reduced; the compressed air pipe is condensed and cooled from different angles, it is guaranteed that a large area of the surface of the compressed air pipe is sprayed with condensed water, and therefore the overall cooling effect is achieved, and the environment-friendly effect is achieved. 本实用新型公开了一种曝气池主管降温装置，包括喷淋嘴框架，所述喷淋嘴框架上设置有多组喷淋嘴，所述喷淋嘴框架设置在管道的上方。本实用新型优点是：在曝气主管上添加冷淋水管，对曝气主管进行喷淋，降低曝气主管温度；从不同角度对压缩空气管进行冷凝降温，保证压缩空气管表面大面积受到冷凝水喷淋，从而达到整体降温的效果，达到了环保的效果。
