[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0013] like Figure 1 , Figure 2 As shown in the embodiment of this utility model, a novel spray tower includes a tower body 1, a tower body 2, a spray vertical pipe 11, a spray horizontal pipe 8, a spray horizontal pipe 9, and a spray horizontal pipe 3 10. The tower body 1 includes an exhaust gas inlet 3, an observation port 4, and an observation port 5. Valves 15, 16, and 17 are respectively installed at the connection points of the spray vertical pipe 11 with the spray horizontal pipes 8, 9, and 3. The spray horizontal pipes 8 and 3 are located inside the tower body 1. The spray horizontal pipe 9 penetrates the tower body 1 and the tower body 2. A packing layer 18 and a packing layer 2 19 are respectively installed below the spray horizontal pipes 8 and 9. The tower body 2 includes an observation port 6, an observation port 7, a demister layer 20, and an exhaust gas outlet 28. The bottoms of the tower body 1 and the tower body 2 are connected.

[0014] Furthermore, the spray horizontal pipe 8 is provided with a plurality of spray heads 12, the spray heads 12 facing upwards; the spray horizontal pipe 9 is provided with a plurality of spray heads 13; the spray heads 13 of the spray horizontal pipe 9 in the tower body 1 face upwards; the spray heads 13 of the spray horizontal pipe 9 in the tower body 2 face downwards; and the spray horizontal pipe 10 is provided with a plurality of spray heads 14, the spray heads 14 facing upwards.

[0015] Furthermore, a circulating water tank 21 is provided at the bottom of the first tower body 1 and the second tower body 2. The lower end of the spray vertical pipe 11 is connected to a circulating water pump 23. The circulating water pump 23 is located in the circulating water tank 22. The medicine storage tank 24 is connected to the circulating water tank 22 through a dosing metering pump 25. A valve 26 and a filter plate 27 are provided at the connection between the circulating water tank 22 and the circulating water tank 21.

[0016] Specifically, when using this invention, the acid and alkali adjusting agents in the storage tank 24 enter the circulating water tank 22 through the metering pump 25. High-concentration acid and alkali waste gas or dust-containing waste gas enters the tower body 1 through the waste gas inlet 3. At the same time, the circulating water pump 23 enters the working state, and valves 15, 16, and 17 are in the open state. The solution containing the acid and alkali adjusting agents in the circulating water tank 22 is sprayed through the spray vertical pipe 11 and then through the spray horizontal pipes 8, 9, and 10. The solution is sprayed in a mist form from spray head 12, spray head 13, and spray head 14. The spray head 12 on spray pipe 18, the spray head 13 inside tower body 11 on spray pipe 29, and the spray head 14 on spray pipe 30 all spray the mist solution upwards. The direction of the mist solution sprayed inside tower body 1 is opposite to the direction of the waste gas flow, increasing the gas-liquid contact area and reaction time. Packing layer 18 and packing layer 19 are respectively installed below spray pipe 18 and spray pipe 29. The packing material in packing layer 18 and packing layer 19 further increases the gas-liquid contact area and slows down the gas-liquid reaction time, allowing the waste gas to fully react with the mist solution. Observation ports 1-4 and 2-5 are used to observe the internal working conditions of tower body 1. After purification and reaction in tower body 1, the waste gas flows from the bottom of tower body 1 into tower body 2. In tower body 2, the spray nozzles 2-13 of the spray pipe 2-9 spray mist solution downwards. The direction of the mist solution spraying out of tower body 2-2 is opposite to the direction of the waste gas flow. The exhaust gas purified by the spray nozzles 13 inside tower body 2 enters the demisting layer 20. After being dehydrated and demisted by the demisting layer 20, the exhaust gas is discharged into the atmosphere or other purification facilities through the exhaust outlet 28. Observation ports 6 and 7 are used to observe the working conditions inside tower body 2. The solution after the gas-liquid reaction in tower body 1 and tower body 2 flows into the circulating water tank 21. By controlling the closing of valve 26, the solution in the circulating water tank 21 can be filtered by the filter plate 27 and then flow into the circulating water tank 22.

[0017] In summary, this utility model improves the efficiency of waste gas purification, reduces the equipment footprint, and simplifies the installation process by adopting an integrated design of a two-stage spray tower. It can meet the pretreatment and purification requirements for high-concentration acidic, alkaline, or dust-containing waste gases.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
