The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] like Figure 1-3As shown in the embodiment of this utility model, a waste gas purification and scrubbing tower includes: a tower body 10, a spray element 20, a filter element 30, a packing element 40, and a circulation element 50; an air inlet 11 is provided above the tower body 10, and an air outlet 12 is provided at one end of the tower body 10 near the packing element 40; the spray element 20, the filter element 30, and the packing element 40 are arranged sequentially from the air inlet 11 to the air outlet 12; the circulation element 50 is located on the outside of the tower body 10 near the spray element 20, the filter element 30, and the packing element 40 to circulate and purify the waste gas inside the tower body 10. In this embodiment, a highly efficient waste gas treatment system is formed by the tower body 10, spray element 20, filter element 30, packing element 40, and circulation element 50. The waste gas enters through the air inlet 11 at the top of the tower body 10 and passes through the spray element 20 for wetting and washing, the filter element 30 for fine filtration, and the packing element 40 for further adsorption and reaction, effectively removing pollutants from the waste gas. The circulation element 50 ensures the continuity of the purification process, strong synergistic work, and improved purification efficiency. The system is compact, easy to operate, and can achieve deep purification of waste gas to meet environmental emission standards.

[0029] like Figure 3 As shown, an exhaust guide plate 13 is provided inside the tower body 10 near the exhaust port 12. The exhaust guide plate 13 is connected to the exhaust port 12 to form an exhaust channel 14 inside the tower body 10. In this embodiment, through the effective connection between the exhaust guide plate 13 and the exhaust port 12, a clear exhaust channel 14 is constructed inside the tower body 10, optimizing the guidance and distribution of airflow. This allows the purified waste gas to be discharged smoothly and orderly from the tower body 10, reducing airflow turbulence and demonstrating strong practicality.

[0030] A liquid collection tank 15 is provided below the gas outlet channel 14 in the tower body 10. Multiple liquid collection connectors 16 are provided near the liquid collection tank 15 in the tower body 10, arranged around the outer side of the tower body 10. In this embodiment, the liquid collection tank 15 effectively collects the liquid generated during the washing process. To enhance collection efficiency and flexibility, multiple liquid collection connectors 16 are configured in the area adjacent to the liquid collection tank 15 in the tower body 10, facilitating subsequent unified recovery and treatment of the liquid.

[0031] The spray element 20 includes a spray pipe 21 and spray nozzles 22. Multiple spray nozzles 22 are provided, with one end of each nozzle evenly distributed on the spray pipe 21 and facing the filter element 30. In this embodiment, the spray element 20, composed of the spray pipe 21 and multiple evenly distributed spray nozzles 22, achieves efficient spraying operation of the waste gas purification scrubbing tower. The multiple nozzles ensure that the spray liquid evenly covers the surface of the filter element 30, effectively increasing the contact area between the waste gas and the spray liquid, thereby improving the pollutant removal rate in the waste gas.

[0032] A spray pipe 21 is arranged in a ring at the air inlet 11. A control valve 23 is provided at one end of the spray pipe 21, which controls the delivery of the spray pipe 21. In this embodiment, by arranging the spray pipe 21 in a ring at the air inlet 11, efficient contact between the waste gas and the washing liquid is achieved. The control valve 23 at one end of the spray pipe 21 allows for precise control of the liquid delivery of the spray pipe 21, thereby optimizing the washing effect and saving resources. This ensures that the waste gas is evenly washed by the spray liquid after entering the scrubbing tower, enhancing the removal efficiency of pollutants in the waste gas.

[0033] The filter element 30 includes a filter plate 31, on which filter mesh 32 is evenly distributed, and the mesh size of the filter mesh 32 is different. In this embodiment, by evenly distributing filter mesh 32 of different sizes on the filter plate 31, precise interception of pollutants of different particle sizes is achieved. The mesh allows gas to pass through smoothly, reducing resistance, while the small-sized mesh effectively captures fine particulate matter, improving purification efficiency.

[0034] A sealing strip 33 is fitted around the outer periphery of the filter plate 31. The filter plate 31 is encircled within the tower body 10 by the sealing strip 33 to form a sealing layer 34 within the tower body 10. In this embodiment, the sealing strip 33 around the outer periphery of the filter plate 31 effectively seals the filter plate 31 and the tower body 10, forming a stable sealing layer 34. This effectively prevents leakage of waste gas during the purification process and ensures the efficient operation of the waste gas purification scrubbing tower.

[0035] The packing element 40 includes a first packing layer 41 and a second packing layer 42, wherein the thickness of the first packing layer 41 is greater than the thickness of the second packing layer 42. In this embodiment, by increasing the thickness of the first packing layer 41, the gas-liquid contact area is effectively increased, enhancing the interaction between the waste gas and the scrubbing liquid, thereby improving the purification efficiency. Furthermore, the design of packing layers with different thicknesses helps to optimize the airflow distribution, reduce pressure drop, and ensure smooth airflow within the tower.

[0036] The first packing layer 41 is a ceramic layer, and the second packing layer 42 is a plastic layer. In this embodiment, the ceramic layer, due to its excellent corrosion resistance, good heat resistance, and surface wetting properties, can effectively treat high-temperature and highly corrosive waste gases while increasing the gas-liquid contact area. The plastic layer, with its lightweight, corrosion-resistant, and easy-to-replace characteristics, further enhances the scrubbing tower's ability to treat acidic and alkaline waste gases, reduces costs, and ensures the safety and economy of waste gas treatment.

[0037] The circulation element 50 includes a circulation pipe 51, a first circulation interface 52, a second circulation interface 53, and a third circulation interface 54. The first circulation interface 52, the second circulation interface 53, and the third circulation interface 54 are sequentially arranged on the circulation pipe 51 to circulate the spray element 20, the filter element 30, and the packing element 40. In this embodiment, the first circulation interface 52, the second circulation interface 53, and the third circulation interface 54 arranged sequentially on the circulation pipe 51 form an efficient circulation path, maximizing resource utilization and achieving cyclical flow.

[0038] A waste gas purification scrubbing tower includes: a tower body 10, a spray element 20, a filter element 30, a packing element 40, and a circulation element 50; an air inlet 11 is provided at the top of the tower body 10, and an air outlet 12 is provided at one end of the tower body 10 near the packing element 40; the spray element 20, the filter element 30, and the packing element 40 are arranged sequentially from the air inlet 11 to the air outlet 12; and the circulation element 50 is located on the outside of the tower body 10 near the spray element 20, the filter element 30, and the packing element 40 to circulate and purify the waste gas inside the tower body 10. In this embodiment, a highly efficient waste gas treatment system is formed by the tower body 10, spray element 20, filter element 30, packing element 40, and circulation element 50. The waste gas enters through the air inlet 11 at the top of the tower body 10 and passes through the spray element 20 for wetting and washing, the filter element 30 for fine filtration, and the packing element 40 for further adsorption and reaction, effectively removing pollutants from the waste gas. The circulation element 50 ensures the continuity of the purification process, strong synergistic work, and improved purification efficiency. The system is compact, easy to operate, and can achieve deep purification of waste gas to meet environmental emission standards.
