Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device. Background Art

[0002] The working principle of the spray tower is mainly to use the contact between gas and liquid to capture pollutants in the gas through droplets. When dusty or oily waste gas passes through the spray tower, the nozzles in the tower will spray liquid media (such as water, acid or alkali solution), which will collide with the pollutants in the waste gas and wrap them. With the action of gravity, the water droplets containing pollutants will fall to the bottom of the tower, thereby purifying the waste gas.

[0003] However, when the dusty exhaust gas is sucked into the spray tower by the exhaust fan, a large amount of dust will adhere to the protective net on the pipeline. With long-term use, the through holes on the protective net will be blocked, seriously affecting the entry of exhaust gas and making it inconvenient to use. Utility Model Content
