[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] like Figs. 1-2This utility model discloses a pig farm odor adsorption and purification device, which includes a storage cylinder 1, an exhaust fan 2, a first housing 3, honeycomb ceramic sheets 4, a first ultraviolet germicidal lamp 5, and a second housing 6. The storage cylinder 1 contains activated carbon, and one side of the storage cylinder 1 is connected to an exhaust pipe 7. A first dustproof net 8 is detachably installed at the front end of the exhaust pipe 7, and the exhaust fan 2 is installed inside the exhaust pipe 7. The other side of the storage cylinder 1 is connected to the first housing 3, and the first housing 3 is connected to a first connecting pipe 10. One end of the first connecting pipe 10 is connected to a second housing 6, which has ventilation holes 11. A honeycomb ceramic sheet 4 is installed inside the first connecting pipe 10, and the honeycomb ceramic sheet 4 is coated with a photocatalytic coating, such as titanium dioxide coating. The honeycomb ceramic sheet has good high temperature resistance, corrosion resistance, and high chemical stability, and can maintain stable performance in various environments. It is not easily deformed or damaged, and has a large specific surface area. The surface of the honeycomb ceramic sheet is relatively rough, which allows the photocatalytic coating to adhere better and form a uniform coating, which is beneficial to the adhesion and function of the photocatalytic coating. The ultraviolet germicidal lamp 5 is installed inside the first housing 3. The top of the storage cylinder 1 is connected to a feed pipe 12 with external threads, and the top of the feed pipe 12 is threadedly connected to a feed cap 13. The bottom of the storage cylinder 1 is connected to a discharge pipe 14 with external threads, and the bottom of the discharge pipe 14 is threadedly connected to a discharge cap 15. The feed cap and the feed pipe, as well as the discharge cap and the discharge pipe, are sealed connections. A fixing plate is provided on one side of the device for easy fixing of the device. The exhaust fan draws air into the storage cylinder. The first dust filter blocks impurities in the air, such as pig hair or dust, providing initial filtration. The air then comes into full contact with activated carbon in the storage cylinder. Activated carbon has a highly developed pore structure and a large specific surface area, with pores of varying sizes, including micropores, mesopores, and macropores. These pores provide numerous adsorption sites, allowing odor molecules to diffuse into the pores of the activated carbon and be adsorbed onto the pore surface, thus removing odors. For example, the micropores of activated carbon can effectively capture small molecule gases such as ammonia and hydrogen sulfide, which are common in pig farm odors. Photocatalytic coatings have a good decomposition effect on organic odor substances. In a pig farm environment, they can decompose various organic odor substances produced by pig excrement, such as skatole and indole, into harmless small molecules through a series of oxidation reactions, thereby purifying the odor. Photocatalytic coatings continuously generate free radicals under the ultraviolet light of UV germicidal lamps, enabling sustained decomposition of air odors and sterilization, resulting in a long-term and stable purification effect. The storage cylinder features an inlet pipe and threaded inlet cover at the top, and an outlet pipe and threaded outlet cover at the bottom, facilitating easy disassembly and replacement of the inlet and outlet covers, and enhancing the air purification effect.

[0019] The storage cylinder 1 is equipped with a stirring assembly for stirring activated carbon. The stirring assembly includes a stirring motor 16, a stirring shaft 17, and stirring rods 18. The stirring motor 16 is installed at the top of the storage cylinder 1. The stirring shaft 17 is rotatably installed inside the storage cylinder 1, and one end of it rotatably passes outside the storage cylinder and is connected to the output shaft of the stirring motor 16. Multiple stirring rods 18 are symmetrically installed on the stirring shaft 17. During the air purification process, the stirring motor is started, causing the stirring shaft to rotate, which in turn drives the stirring rods to rotate and stir the activated carbon, allowing the odorous air to fully contact the activated carbon and enhancing the adsorption and purification effect of air odors.

[0020] The exhaust pipe 7 has an external thread at its front end, and the first dustproof net 8 has an internal threaded pipe installed on one side. The first dustproof net 8 is threadedly connected to the front end of the exhaust pipe 7. The air contains various impurities, such as dust or pig hair. During the exhaust process, the first dustproof net can filter the air impurities. After a long time, the impurities accumulate on the first dustproof net, affecting the ventilation effect. The first dustproof net is threaded, which makes it easy to remove the first dustproof net for cleaning or replacement.

[0021] The second chamber 6 is equipped with a second ultraviolet germicidal lamp 19; the second ultraviolet germicidal lamp is set to enhance the air purification effect.

[0022] The bottom of the storage cylinder 1 is conical; the bottom of the storage cylinder is conical, and the discharge pipe is installed at the bottom of the conical body, which makes it easy for the activated carbon inside the storage cylinder to fall out and facilitates the replacement of activated carbon.

[0023] The storage cylinder 1 has two second connecting pipes 20 symmetrically connected at its upper and lower ends on the side away from the exhaust pipe. One end of the second connecting pipe 20 is connected to the first box 3. The air drawn into the storage cylinder enters the first box through the two second connecting pipes after being adsorbed by the activated carbon, so that the air can fully contact the activated carbon.

[0024] Both the exhaust pipe 7 and the second connecting pipe 20 have a mesh 9 installed at one end near the storage cylinder; the mesh is installed to isolate the activated carbon and prevent it from entering the exhaust pipe or the second connecting pipe.

[0025] The second housing 6 has two ventilation holes 11 symmetrically arranged at the top and bottom ends on one side. The purified air flows out through the ventilation holes, and a second dustproof net 21 is installed on the outside of the ventilation holes 11.

[0026] Work process:

[0027] The working principle of this utility model is as follows: The exhaust fan 2 inside the exhaust pipe 7 draws in air, which then passes sequentially through the storage cylinder 1, the first chamber 3, and the second chamber 6. The storage cylinder 1 contains activated carbon, which can absorb odors from the air. During the air purification process, the stirring rod 18 of the stirring component stirs the activated carbon, ensuring it is in full contact with the air and enhancing the purification effect. The activated carbon can be replaced after a period of time. A honeycomb ceramic sheet 4 coated with photocatalytic paint is installed between the first chamber 3 and the second chamber 6. A first ultraviolet germicidal lamp 5 is installed in the first chamber 3, and a second ultraviolet germicidal lamp 19 is installed in the second chamber 6, sterilizing the air. Simultaneously, under the ultraviolet light of the ultraviolet germicidal lamp, the photocatalytic paint continuously generates free radicals, continuously decomposing odors and sterilizing, thus enhancing the air purification effect.
