Technical Field

[0001] This utility model relates to the technical field of odor purification devices, and more specifically to a livestock odor purification device. Background Technology

[0002] Currently, common methods for odor control in egg-laying hen farms include physical and chemical methods. Physical methods, such as activated carbon adsorption, have limited adsorption capacity, requiring frequent replacement and resulting in high costs. Chemical methods, such as spraying deodorizers to neutralize odors, may introduce new chemical substances, posing a risk of secondary pollution. Utility Model Content

[0003] The purpose of this invention is to provide a livestock odor purification device that improves the purification effect and effectively removes dust impurities and harmful odor components such as ammonia and hydrogen sulfide from the air.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An odor purification device for livestock farming includes a purification box with legs at the bottom, an air inlet at the bottom, and an air outlet at the top. Inside the purification box, from bottom to top, there are a metal filter, a fiber felt filter layer, and an activated carbon adsorption layer. An ultraviolet lamp and a titanium dioxide catalytic mesh are arranged between the fiber felt filter layer and the activated carbon adsorption layer. A fan is located above the activated carbon adsorption layer.

[0006] Furthermore, the ultraviolet lamps are provided in two sets. One set of ultraviolet lamps is located between the fiber felt filter layer and the titanium dioxide catalytic mesh, and the other set of ultraviolet lamps is located between the titanium dioxide catalytic mesh and the activated carbon adsorption layer. The ultraviolet lamps are installed on the inner wall of the purification box.

[0007] Furthermore, the fan is a silent fan.

[0008] Furthermore, an inspection door is provided on one side of the purification box.

[0009] Furthermore, four support legs are provided, and the four support legs are respectively located at the four corners of the bottom of the purification box, with a protective mesh connecting adjacent support legs.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This application achieves multi-step treatment of odorous gases from livestock farming through a layered setup of a metal filter, a fiber felt filter layer, an ultraviolet lamp and a titanium dioxide catalytic mesh, and an activated carbon adsorption layer. This process involves "initial dust removal → fine filtration → photocatalytic decomposition → deep adsorption," progressively enhancing the purification effect and effectively removing dust impurities and harmful odor components such as ammonia and hydrogen sulfide from the air.

[0015] like Figure 1 and Figure 2 As shown, a livestock odor purification device includes a purification box 1. The bottom of the purification box 1 is provided with support legs 2. The bottom of the purification box 1 is provided with an air inlet 101 and the top of the purification box 1 is provided with an air outlet 102. The purification box 1 is provided with a metal filter screen 3, a fiber felt filter layer 4 and an activated carbon adsorption layer 5 arranged sequentially from bottom to top. An ultraviolet lamp 6 and a titanium dioxide catalytic mesh 7 are provided between the fiber felt filter layer 4 and the activated carbon adsorption layer 5. A fan 8 is provided above the activated carbon adsorption layer 5.

[0016] The ultraviolet lamps 6 are provided in two sets. One set of ultraviolet lamps 6 is located between the fiber felt filter layer 4 and the titanium dioxide catalytic mesh 7, and the other set of ultraviolet lamps 6 is located between the titanium dioxide catalytic mesh 7 and the activated carbon adsorption layer 5. The ultraviolet lamps 6 are installed on the inner side wall of the purification box 1. The two sets of ultraviolet lamps 6 are respectively arranged on the upper and lower sides of the titanium dioxide catalytic mesh 7 to achieve uniform irradiation on both sides of the titanium dioxide catalytic mesh 7. This ensures that the odor components in the airflow are fully exposed to ultraviolet light when passing through the titanium dioxide catalytic mesh 7, improves the comprehensiveness of the photocatalytic reaction, and avoids the treatment blind spots that may be caused by unilateral irradiation.

[0017] The titanium dioxide catalytic mesh 7 is made of a honeycomb ceramic substrate supported by a nano-TiO2 (titanium dioxide) coating.

[0018] The fan 8 is a silent fan; the silent fan operates with low noise, reducing the stress of equipment operation on laying hens and creating a more stable breeding environment.

[0019] The purification chamber 1 is provided with an inspection door 9 on one side; the inspection door 9 facilitates quick opening of the chamber to inspect, clean or replace internal components such as the filter layer and ultraviolet lamp.

[0020] The four support legs 2 are respectively located at the four corners of the bottom of the purification box 1, and a protective net 10 is connected between two adjacent support legs 2. The support legs 2 raise the purification box 1 and, together with the bottom protective net 10, can effectively prevent chickens from entering the bottom of the purification box 1.

[0021] Working principle:

[0022] Odor-laden air enters through the air inlet 101 at the bottom of the purification chamber 1. First, it passes through the metal filter 3 to remove large particles such as feathers and feed residue. Then, it passes through the fiber felt filter layer 4 to further remove fine dust, completing the initial filtration of solid pollutants. Subsequently, the air enters the area of ​​the ultraviolet lamp 6 and the titanium dioxide catalytic mesh 7. The ultraviolet light excites the titanium dioxide to produce strong oxidizing substances, which decompose odor components such as ammonia and hydrogen sulfide into harmless gases. The air treated by photocatalysis continues to rise through the activated carbon adsorption layer 5, where the adsorption capacity of the activated carbon removes residual odors and volatile organic compounds. Finally, the purified air is discharged by the top fan 8 and sent back to the breeding farm, forming an air self-circulation.

[0023] In addition, the air outlet 102 can also be connected to the air distribution system in the farm, so that the purified air can be evenly delivered to the farm.

[0024] This invention combines physical filtration, photocatalytic decomposition, and activated carbon adsorption, breaking through the limitations of traditional single purification methods. It utilizes photocatalysis to enhance the ability to treat complex odor components, resulting in a more comprehensive and lasting purification effect compared to traditional solutions.
