[0002] Waste gas treatment, also known as waste gas purification, refers to the pre-treatment of waste gas generated in industrial sites, factory workshops, etc. before external discharge to meet national waste gas emission standards. There are many ways to treat waste gas, each with its own specific application scenarios and advantages.

[0003] Complex composition of waste gas: waste gas may contain a large amount of suspended particulate matter, moisture, sticky impurities, etc. These components are easy to adhere to the inner wall of the tower or the surface of the filler during the treatment process, forming a film that gradually thickens and eventually leads to blockage. Improper equipment design or selection: the design of the waste gas treatment tower may not fully consider the characteristics and treatment requirements of the waste gas. Improper selection of tower structure, filler type, spray system, etc. will affect the treatment effect and fluidity of the waste gas. Improper operation and maintenance: the lack of regular maintenance and cleaning of the equipment during operation, or improper operation resulting in reduced waste gas treatment efficiency, can also cause blockage problems.

First, the exhaust gas that has completed cooling and dust removal is transported to the bottom end of the guide shell 9 of the base 101 through the pipeline and the flow valve 13, and the guide block 10 is used to guide the airflow, so that the exhaust gas flows evenly upward along the outer wall of the guide shell 9, and then the negative pressure motor 104 is started to drive the drive shaft 6 to rotate, and the vortex fan 11 rotates. This creates negative pressure inside the metal skeleton 7. At this time, the airflow passes through the wet curtain 8 and the metal skeleton 7. When the exhaust gas flows, the purified liquid inside the storage box 102 is pressurized by the booster motor 12, so that the purified liquid flows into the input pipe 14 and the flow valve 13 respectively. The purified liquid is also atomized and sprayed out by the nozzle 3 in one step.

Another part of the purified liquid slowly descends along the spiral scraper 4 to the bottom of the inner wall of the base 101. Then the purified liquid drives the attachments to slowly descend along the spiral scraper 4 to the bottom of the inner wall of the base 101. The sewage composed of the purified liquid and the attachments is discharged through the drain pipe 105 and collected for centralized treatment.
