DETAILED DESCRIPTION

[0026] like Figures 1 to 5 As shown, a deodorizing device includes a deodorizing box 4 installed outside a pig house 1. The top of the deodorizing box 4 is connected to the inside of the pig house 1 through multiple connecting pipes 3. The connecting pipes 3 are provided with exhaust ports 2 at the ends inside the pig house 1. Air intake fans 5 are provided between adjacent exhaust ports 2. The air intake fans 5 are provided with spray coils 6 at the ends inside the pig house 1.

[0027] Deodorizing box 4 is equipped with a multi-layered sliding drawer 401, which contains activated carbon 8 and biological filter material 9. Malodorous air from piggery 1 is drawn into deodorizing box 4 through exhaust port 2 and connecting pipe 3, where it is purified by activated carbon 8 and biological filter material 9 before being discharged. Simultaneously, fresh air is introduced into piggery 1 through intake fan 5, which also circulates the plant extract sprayed from spray coil 6, further reducing odors within piggery 1.

[0028] The air first passes through a drawer containing activated carbon 8, which effectively absorbs volatile organic compounds and other harmful gases in the air. The air then passes through a drawer containing biofilter 9, where microorganisms break down any remaining malodorous components. The purified air is discharged from the deodorizer, minimizing its environmental impact. An intake fan 5 continuously introduces fresh air into the piggery, improving indoor air quality. The intake fan also helps disperse the spray of plant extracts from the spray coil 6; these natural ingredients further reduce airborne odors.

[0029] It integrates multiple methods, including physical adsorption, biodegradation, and natural freshness. The intake fan not only promotes air flow but also helps maintain optimal temperature and humidity within the piggery. The use of natural materials and technologies reduces reliance on chemical agents, making it more environmentally friendly. The drawer-type design facilitates replacement of activated carbon and biofilter media, simplifying daily maintenance.

[0030] Preferably, a first exhaust fan 201 is provided in the exhaust port 2, and a first grille 202 is fixed at the end of the exhaust port 2. The first exhaust fan 201 can suck the air in the pig house 1 into the exhaust port 2, and the first grille 202 can play a blocking role to prevent foreign matter from entering.

[0031] The first exhaust fan is used to force air from the piggery into the exhaust port and transport it to the external deodorizing box 4 through the connecting pipe 3. This helps to improve the collection efficiency of malodorous gases and ensures that odors in the piggery can be effectively removed even when natural ventilation conditions are poor.

[0032] The first grille is installed at the end of the exhaust port. Its main function is to prevent large particles, dust, or other foreign matter from entering the exhaust system. This protects internal equipment, such as the connecting pipes and the activated carbon layer and biological filter media in the deodorizer, from becoming clogged or contaminated, which could reduce their efficiency.

[0033] Preferably, a second exhaust fan 10 is provided at the bottom of the deodorizing box 4. The second exhaust fan 10 and the first exhaust fan 201 work together to make the odor purification and circulation in the pig house 1 smoother.

[0034] The two fans work together to create an efficient airflow path, increasing air velocity and reducing the time malodorous gases remain inside the piggery. This more stable and powerful airflow allows for better contact between malodorous gases and the activated carbon and biofilter media, enhancing purification effectiveness. By placing fans at both ends of the system, pressure loss in the piping is effectively reduced, making the entire system more efficient. The speeds of the two fans can be adjusted to meet ventilation needs in different seasons or weather conditions.

[0035] Preferably, the outer side of the spray coil 6 is fixedly connected to the air intake fan 5 via a plurality of connecting blocks 601;

[0036] A liquid inlet pipe 7 is installed on the outside of the pig house 1. The top of the spray coil 6 is connected to the liquid inlet pipe 7 via a branch pipe 602. The spray coil 6 is fixed to the air outlet of the air intake fan 5 via multiple connecting blocks 601. When the air intake fan 5 blows, the plant extract sprayed from the spray coil 6 is sprayed into the pig house 1. The liquid inlet pipe 7 is connected to the liquid storage tank via a pump. The plant extract in the storage tank is pumped into each spray coil 6 by pumping, and then sprayed out as an atomized liquid.

[0037] The plant extract in the storage tank is pressurized by a pump and delivered to the liquid inlet pipe 7. The plant extract then flows through branch pipes 602 into the spray coils 6. Once the plant extract reaches the spray coils 6, it is atomized into fine particles by the nozzles, forming a spray. This spray is carried by the airflow generated by the intake fan 5 and evenly distributed throughout the piggery.

[0038] The intake fan 5 not only draws fresh air into the piggery but also helps propel the spray throughout the space. This allows the plant extract spray to cover a wider area, more effectively removing or masking odors within the piggery. The natural ingredients in the plant extract spray physically adsorb and chemically react with odor molecules, reducing the concentration of odor in the air. Furthermore, the refreshing aroma of the plant extract helps improve air quality within the piggery, creating a more comfortable environment.

[0039] Preferably, a second grille 501 is fixedly provided on the outside of the air intake fan 5. The second grille 501 can prevent foreign matter such as dust, leaves, and small animals from entering the air intake fan 5 and the interior of the pig house, thereby protecting the air intake fan and other internal equipment from damage.

[0040] Preferably, the spray coil 6 is equipped with multiple atomizing nozzles. These nozzles, through their unique structural design, break down liquid into tiny particles, creating a dense spray that increases contact with odor molecules in the air. Multiple atomizing nozzles distributed across the spray coil cover a larger area, ensuring even distribution of the spray throughout the piggery.

[0041] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
