[0002] A spray tower is a device commonly used for treating exhaust gases. It adopts an efficient spraying technique to atomize the treatment liquid into tiny particles, and through contact with the waste gas, the purpose of purifying the waste gas is achieved. It is widely used in various industries such as chemical engineering, electric power, and metallurgy;

[0003] For example, the public notice document: CN220633716U, named "A Spray Tower Convenient for Cleaning". The bottom of both sides of the scraper contacts the lower inner walls of both sides of the dirt box, pushing the dirt accumulated on the inner wall of the dirt box outward, and the dirt is pushed out of the dirt box through one end of the dirt box for cleaning. Through the sponge pad located behind the scraper, which contacts the inner wall of the dirt box, the dirt box after being cleaned by the scraper is deeply cleaned.

[0004] The above-mentioned existing spray tower uses a wiping method to clean the inner wall, resulting in frequent replacement of the wiping parts, which is rather inconvenient. Moreover, the wiping range can only act on the lower bottom of the spray tower, and the cleaning range is small, and the inner wall of the tower cannot be cleaned; therefore, it does not meet the existing requirements, and for this reason, we propose a spray tower convenient for internal cleaning.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a spray tower convenient for internal cleaning, comprising: a spray tower main body 1, an outer bottom of one side of the spray tower main body 1 is provided with an outer box body 5, a pump body 7 is arranged above the outer box body 5, one end of the pump body 7 is provided with a delivery pipe 8, one end of the delivery pipe 8 is provided with a spray assembly 9, and the spray assembly 9 is located inside the spray tower main body 1. The spray assembly 9 includes a multi-way assembly pipe 10, and one end of the multi-way assembly pipe 10 is communicated with the delivery pipe 8. Both ends of the multi-way assembly pipe 10 are provided with side spray frames 12, a plurality of side spray nozzles 13 are arranged on the outer wall of the side spray frames 12, a first control valve 11 is arranged at one end of the side spray frame 12 close to the multi-way assembly pipe 10. A middle spray frame 14 is connected to the middle position of the multi-way assembly pipe 10 through the first control valve 11, and a plurality of lower spray nozzles 15 are arranged on the lower surface of the middle spray frame 14. The spray assemblies 9 are arranged at intervals up and down inside the spray tower main body 1, and a packing layer 16 is arranged below each spray assembly 9. A swirl demisting layer 17 is arranged at the inner top of the spray tower main body 1, an air outlet 4 is arranged at the upper end of the swirl demisting layer 17, a maintenance manhole 2 is arranged on the outer wall of the spray tower main body 1, a ventilation hole 3 is arranged below the maintenance manhole 2, and the ventilation hole 3 is located above the water receiving tank 18;

[0022] The principle of this spray tower is as follows: It is connected to the external delivery pipe 8 through the multi-way assembly pipe 10. When the spray tower is in use, waste gas enters from the ventilation hole 3 at the bottom of the tower body, and then evenly rises into the packing layer 16. On the surface of the packing, dirt in the gas reacts with chemical substances in the liquid, and the generated soluble substances flow into the lower water receiving tank 18 along with the absorption liquid. The gas that is not completely absorbed continues to rise and enters the spray section. The lower spray nozzles 15 spray at high speed to form countless tiny liquids that are fully mixed and contacted with the gas, and continue to undergo chemical reactions. The purified gas passes through the swirl demisting layer 17 at the top of the tower body, and after removing the entrained absorption liquid droplets, it is discharged from the air outlet 4;

[0023] During cleaning, the first control valve 11 controls the middle spray frame 14 to close and opens the side spray frames 12. The required cleaning water is filled in the outer box body 5, and the water body is pumped to the side spray frames 12. The cleaning water is sprayed out through the side spray nozzles 13. Since the side spray frames 12 are arc-shaped structures and the side spray nozzles 13 are spaced apart on the outer side wall of the side spray frames 12, the sprayed cleaning water can clean the inner wall of the tower, and the cleaning water flows down along the inner wall of the tower into the water receiving tank 18 for collection; By improving the spray assembly 9 inside the spray tower, during the cleaning process, the inner wall of the tower can be cleaned by side spraying. The spraying range is large, and the inner wall of the tower can be effectively sprayed and cleaned. Compared with cleaning structures such as wiping parts, it does not need to be frequently replaced, has higher efficiency, and can be controlled by a control valve, which is convenient for users to use.

[0024] Please refer to Figure 3 Figure 3 , a water receiving tank 18 is provided at the inner bottom of the spray tower main body 1. A second control valve 19 is provided between the water receiving tank 18 and the outer box body 5. A drain port 6 is provided on one side of the outer box body 5 away from the spray tower main body 1. The opening and closing states of the water receiving tank 18 and the outer box body 5 can be controlled by the second control valve 19, which is convenient for the user to connect or close the two. In the connected state, the operation of recycling water can be carried out. In the closed state, the water bodies in the outer box body 5 and the water receiving tank 18 can be separated, so that they can be used independently.

[0025] Working principle: It is connected through a multi-pass assembly pipe 10 to an external delivery pipe 8. When the spray tower is in use, the waste gas enters from the ventilation hole 3 at the bottom of the tower body, and then evenly rises into the packing layer 16. On the surface of the packing, the dirt in the gas reacts with the chemical substances in the liquid, and the generated soluble substances flow into the lower water receiving tank 18 along with the absorption liquid. The gas that is not completely absorbed continues to rise and enters the spray section. The lower spray heads 15 spray at high speed to form countless tiny liquids that are fully mixed and contacted with the gas, and continue to undergo chemical reactions. The purified gas passes through the swirl demisting layer 17 at the top of the tower body, and after removing the entrained absorption liquid droplets, it is discharged from the air outlet 4;

[0026] During cleaning, the first control valve 11 controls the middle spray rack 14 to close, and the side spray rack 12 is opened. The required cleaning water is loaded into the outer box body 5, and the water body is pumped to the side spray rack 12. The cleaning water is sprayed out through the side spray heads 13. Since the side spray rack 12 is an arc-shaped structure, and the side spray heads 13 are distributed at intervals on the outer side wall of the side spray rack 12, the sprayed cleaning water can clean the inner wall of the tower, and the cleaning water flows down along the inner wall of the tower into the water receiving tank 18 for collection.

[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
