Technical Field

[0001] This utility model relates to a scrubbing tower, specifically a chemical scrubbing tower that is not easily clogged, belonging to the technical field of chemical gas purification equipment. Background Technology

[0002] In the chemical industry, scrubbing towers are key equipment for treating waste gas and purifying air.

[0003] For example, the chemical washing tower that is not prone to clogging disclosed in patent publication number CN222510818U can prevent clogging by setting up a vibration lifting device, which can drive the tower body and other structures to vibrate when needed through various vibrators. In addition, the operator can move the position of the washing tower by using various brake wheels when needed. Furthermore, the operator can adjust the height of the tower body and other structures by using the cooperation of threaded holes and support plates, thereby improving the working capacity of the washing tower.

[0004] While the existing equipment can improve the working capacity of the scrubbing tower, it is not convenient to isolate the spray heads from the gas inside the scrubbing tower when they are not in use, thus failing to improve the anti-clogging effect of the spray heads. In addition, this type of equipment has the problem of low efficiency in filtering and purifying chemical gases.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content
