[0002] In the process of waste paper recycling and regeneration, pollutants such as dust, volatile organic compounds, and acidic gases are generated. Waste gas treatment spray towers are often used to purify waste gas. Pollutants are removed by liquid absorption, which effectively purifies waste gas and protects the environment. The spray range inside the spray tower is not wide enough, which will make the contact between the waste gas treatment liquid and the waste gas not uniform.

[0003] The waste gas treatment spray tower for waste paper raw material production disclosed in Chinese patent CN217646174U is connected to the first liquid distribution assembly by rotation through a cross bar on the inner wall of the connecting plate. The treatment liquid rushes toward the rotating plate, and the rotating plate can drive the cylinder to rotate, so that the spray range of the treatment liquid is larger. The right side wall of the cylinder is rotatably connected to the second liquid distribution assembly through a connecting rod A, so that the contact between the treatment liquid and the waste gas is more uniform.

[0004] In actual application, it is found that the treated liquid after the reaction of the above device accumulates at the bottom of the tower, and the above device is not convenient for treating the treated liquid after the reaction. In the prior art, the treated liquid accumulated at the bottom of the tower is often circulated and sprayed through a circulating pump, but the solid particles and suspended matter in the spray liquid will cause the nozzle to be blocked. For this reason, we provide a waste gas treatment spray tower for waste paper raw material production. Utility Model Content
