Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a waste gas treatment absorption tower. Background Technology

[0002] Alkali scrubbing towers, also known as acid-alkali washing towers or acid-alkali waste gas neutralization treatment towers, are a type of equipment used for environmental purification of waste gas generated in industrial production. They are a type of waste gas purification tower and are also called purification towers or absorption towers. Based on the material, they are divided into carbon steel alkali scrubbing towers and fiberglass alkali scrubbing towers.

[0003] In existing multi-stage alkali absorption towers, the neutralization liquid spraying effect is not uniform during operation, making it difficult to completely absorb the waste gas. This affects the overall absorption quality of the alkali absorption tower and reduces the absorption effect.

[0004] The existing Chinese patent CN219784331U waste gas treatment absorption tower, in solving the above problems, only has a movable sealing connection between its liquid inlet pipe and spray pipe. However, the spray pipe needs to rotate. It is unclear how the rotating spray pipe can ensure the sealing between the liquid inlet pipe and the spray pipe. Therefore, this device cannot be implemented and is not suitable for widespread use. Utility Model Content

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a waste gas treatment absorption tower, including a tower body 1, four support legs 2 fixedly connected to the bottom of the tower body 1, the four support legs 2 are arranged in a rectangular array, a number of packing plates 4 are fixedly connected to the inner cavity of the tower body 1, and a number of air inlet pipes 3 are fixedly inserted into the left side of the tower body 1, the number of air inlet pipes 3 and the packing plates 4 are arranged alternately.

[0024] An exhaust pipe 5 is fixedly inserted into the top of the tower body 1 near the left side. A sealing bearing 6 is fixedly inserted into the top of the tower body 1. A spray pipe 7 is fixedly inserted through the inner cavity of the sealing bearing 6. Several packing plates 4 are movably inserted through the bottom end of the spray pipe 7. Several connecting pipes 8 are fixedly inserted into both sides of the spray pipe 7. A spray head 9 is fixedly connected to the end of the connecting pipe 8 away from the spray pipe 7. Several discharge holes 10 are opened on the outer edge of the spray head 9. The discharge holes 10 are arranged in an array. A storage tank 11 is provided at the top of the spray pipe 7. The top of the spray pipe 7 is fixedly inserted into the bottom of the storage tank 11. The spray pipe 7 and the storage tank 11 are interconnected. A conveying pipe 12 is provided on the right side of the tower body 1. A drain pipe 13 is fixedly connected to the bottom end of the conveying pipe 12. A water pump 14 is provided at the bottom end of the drain pipe 13. A suction pipe 15 is provided in front of the water pump 14. The discharge end of the conveying pipe 12 is located directly above the storage tank 11.

[0025] A first bevel gear 16 is fixedly fitted on the outer edge of the spray pipe 7 near the top. A second bevel gear 17 is provided on the right side of the first bevel gear 16 and meshes with it. A motor 18 is provided on the right side of the second bevel gear 17. The motor 18 is fixedly connected to the top of the tower body 1, and the power output end of the motor 18 is fixedly connected to the second bevel gear 17.

[0026] Working Principle: In operation, the waste gas treatment absorption tower of this invention connects the extraction pipe 15 to an external tank storing the spray liquid. An external power source starts the water pump 14 and motor 18. The water pump 14 transfers the spray liquid from the extraction pipe 15 to the discharge pipe 13 and the conveying pipe 12, finally reaching the inner cavity of the storage tank 11. The spray liquid then flows downwards under gravity and is finally sprayed out from the discharge hole 10 on the spray head 9. The motor 18 drives the second bevel gear 17 to rotate slowly, which in turn drives the first bevel gear 16 to rotate. The spray pipe 7 and the storage tank 11 rotate slowly. Only slow rotation is needed to avoid the centrifugal force of the rotating storage tank 11 throwing out the spray liquid inside. The spray pipe 7 drives the spray head 9 to rotate, so that the spray liquid is evenly sprayed on the packing plate 4. Each set of packing plates 4 is filled with absorbent material on top, which can further absorb and treat the waste gas. Compared with the existing technology, this device achieves uniform spraying of spray liquid through the slow-rotating spray pipe 7 and the storage tank 11. The spray pipe 7 and the storage tank 11 are integrated, so there is no need to consider the sealing. It is suitable for widespread use.
