Description

Technical Field

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

[0002] With the rapid development of modern industry, industrial waste gas is also generated. In most cases, industrial waste gas is inevitable. Since waste gas will cause environmental pollution, waste gas needs to be processed before discharge. The problem of waste gas treatment has always restricted the development of enterprises. The high cost of waste gas treatment has always been a major problem faced by enterprises.

[0003] Authorization announcement number CN219091586U discloses a waste gas treatment absorption tower. The patented technology is provided with a driving motor, gears, rotating pipe, liquid inlet pipe, spray barrel and spray head. Only by starting the driving motor, the rotating pipe, spray barrel and spray head can be rotated, so that the treatment liquid can be sprayed out evenly to facilitate full mixing with the waste gas. By providing a concentric shaft, cam, five-way pipe, vertical block, air inlet pipe, stabilizer bar and spring, when the spray barrel rotates, the concentric shaft can drive the cam to rotate, and then squeeze the vertical block to move. Then, the stabilizer bar can stretch the spring, so that the exhaust pipe can move back and forth laterally, so that the exhaust gas is evenly discharged into the tower body and fully mixed with the treatment liquid to improve the treatment efficiency; however, in this scheme, when treating the exhaust gas, the treatment liquid used is not ideal for treating the exhaust gas, which is easy to cause secondary pollution, resulting in unclean exhaust gas treatment and inability to discharge fixed sediments. In addition, when spraying, driving mechanisms such as motors, gears and rotating pipes are used, which greatly increases the investment cost of the equipment. Therefore, a waste gas treatment absorption tower is needed to improve the above problems. Utility Model Content
