When this ozone is released into the production workshop, it pollutes the working environment. People exposed to ozone in the air may experience coughing, difficulty breathing, and decreased lung function. Ozone can also participate in the reactions of unsaturated fatty acids, amino acids, and other proteins in organisms, causing fatigue, coughing, chest tightness and chest pain, wrinkled skin, nausea, headache, rapid pulse, memory loss, and decreased vision in people who are directly exposed to high concentrations of ozone for a long time. To avoid the harm of ozone to the human body in the environment, it is necessary to decompose and purify the ozone in the emitted exhaust gas. Utility Model Content

[0003] The purpose of this invention is to provide an ozone decomposition and purification device, which is connected to an exhaust fan through a pipe, so that the exhaust fan inside the device introduces the ozone generated during the activation operation into the ozone decomposition and purification device, and discharges it after purification by the ozone decomposition and purification device, effectively reducing the pollution of ozone to the production environment.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figure 1 , Figure 2 and Figure 3This embodiment provides an ozone decomposition and purification device, which includes a housing 10. The bottom of the housing 10 is provided with multiple casters 14 with brakes for easy movement. Inside the housing 10 are multiple inner plates 20, which together form an ozone purification chamber 21. A gap exists between the inner plates 20 and the inner wall of the housing 10, thus forming a heat-insulating chamber 22 between the inner plates 20 and the housing 10. The heat-insulating chamber 22 is filled with heat-insulating cotton. Furthermore, on both sides of the housing 10 are respectively provided an ozone inlet connection 11 and a purified gas connection 12 communicating with the ozone purification chamber 21. Connection port 11 is connected to an exhaust fan via a pipe, allowing ozone to be discharged into the ozone purification chamber 21 through the exhaust fan. After being purified by the ozone purification chamber 21, the ozone is directly discharged from the purified gas connection port 12, or the purified gas connection port 12 discharges the gas to the outside through a pipe. Multiple catalytic filter mechanisms 30 are sequentially inserted into the ozone purification chamber 21 along the direction from the ozone inlet connection port 11 to the purified gas connection port 12. By sequentially setting multiple catalytic filter mechanisms 30, ozone flows through each catalytic filter mechanism 30 one by one, realizing the step-by-step decomposition and purification of ozone, effectively improving the ozone purification effect.

[0020] As the catalytic filter mechanism 30 deteriorates with prolonged use, it requires regular replacement. To facilitate replacement and maintenance, an insertion port 13 is provided on the top of the outer casing 10 for inserting the catalytic filter mechanism 30. The inner plate 20 at the top also has an inner plate insertion port 23 corresponding to the outer casing insertion port 13. Insertion guide rails 24, fixed to the side walls of the inner plate 20, are provided on both sides of the inner plate insertion port 23. These guide rails 24 have guide grooves. When installing the catalytic filter mechanism 30, align the bottom sides of the catalytic filter mechanism 30 with the outer casing insertion port 13 and push it downwards to insert both sides into the guide grooves. The catalytic filter mechanism 30 is then inserted into the bottom of the ozone purification chamber 21 along the guide grooves. This insertion method facilitates the installation and replacement of the catalytic filter mechanism 30. Furthermore, the guide grooves, in conjunction with the catalytic filter mechanism 30, effectively prevent ozone from passing through the catalytic filter mechanism 30 and the insertion end of the guide grooves.

[0021] Because there is a gap between the catalytic filter mechanism 30 and the top of the housing 10, ozone can easily leak through this gap. Therefore, a sealing structure is provided at each contact point between the catalytic filter mechanism 30 and the housing 10. This sealing structure includes a sealing gasket 40 made of silicone material. The catalytic filter mechanism 30 is screwed onto the top of the housing 10, ensuring the sealing gasket 40 fits tightly against the top of the housing 10. This effectively prevents ozone leakage from the gap between the catalytic filter mechanism 30 and the housing 10, improving the sealing performance and purification efficiency of the ozone decomposition and purification device. Simultaneously, the silicone material has good elasticity and wear resistance, enabling it to maintain its sealing performance over a long period.

[0022] Please see Figure 4 The catalytic filtration mechanism 30 is used to purify the ozone entering the ozone purification chamber 21. In this embodiment, the catalytic filtration mechanism 30 includes a catalytic filter screen 31 with several vent holes and a frame 32 surrounding and fixing the catalytic filter screen 31. Connecting posts 33 are provided on both sides of the top of the frame 32, and a filter screen lifting plate 34 is connected to the two connecting posts 33. The filter screen lifting plate 34 is pivotally connected to a folding handle 35, and a sealing gasket 40 is provided at the bottom of the filter screen lifting plate 34. The height of the connecting posts 33 is fixed at the same level as the heat insulation chamber 22. The filter screen lifting plate 34 and the folding handle 35 facilitate the upward lifting of the catalytic filtration mechanism 30, thereby facilitating its disassembly and improving the ease of assembly and disassembly. The catalytic filter screen 31 is used for catalytic decomposition of ozone, and the frame 32 is used to fix the catalytic filter screen 31, ensuring its stability. The catalytic filter 31 has several vent holes, allowing ozone to come into contact with it and improve its purification efficiency. Connecting posts 33 on both sides of the top of the frame 32 serve as a transition between the frame 32 and the insulation chamber 22, and also support the filter lifting plate 34, ensuring the stability of the filter lifting plate 34 and the folding handle 35. The folding handle 35 can be folded away for storage when not in use, reducing space occupation; it can be unfolded when needed, making operation simple.

[0023] In an optional embodiment, to reduce the overall weight of the catalytic filter mechanism 30 and facilitate lifting by the operator, the frame 32 is made of aluminum alloy. Using aluminum alloy for the frame 32 not only reduces weight but also ensures its strength and durability. Aluminum alloy has excellent corrosion resistance, resisting the erosion of ozone and its potential corrosive substances, thereby extending the service life of the catalytic filter mechanism 30.

[0024] To seal the insulation layer, a cotton insulating element 36 is provided between the outer shell insertion port 13 and the inner plate insertion port 23. The upper and lower ends of the cotton insulating element 36 are fixed to the outer shell 10 and the inner plate 20 by welding, and sealing gaskets can be installed at the upper and lower ends of the cotton insulating element 36 to prevent ozone from leaking from the gap in the inner plate insertion port 23. In addition, the cotton insulating element 36 is provided with an insertion interface for the frame 32 to pass through.

[0025] In an optional embodiment, to improve the purification effect of the catalytic filter 31, the catalytic filter 31 is made of a manganese-based metal mixture. Manganese-based metal mixtures have good catalytic activity and can effectively decompose ozone, converting it into harmless oxygen. Simultaneously, using this material to make the catalytic filter 31 also enhances its adsorption and purification capacity for harmful gases, thereby improving the overall purification efficiency of the ozone decomposition purification device. Furthermore, the manganese-based metal mixture only acts as a catalyst for ozone decomposition and does not participate in the reaction itself, significantly extending its lifespan, reducing replacement frequency, and lowering maintenance costs.

[0026] In an optional embodiment, to improve the heat insulation effect of the insulation cotton, it is made of aluminosilicate fiber material. Aluminosilicate fiber insulation cotton possesses excellent heat insulation and high-temperature resistance, effectively preventing heat transfer and maintaining a stable surface temperature of the outer casing 10, thus preventing overheating and the risk of burns. Furthermore, aluminosilicate fiber material also has good corrosion resistance and mechanical strength, while maintaining the structural stability of the insulation cotton, making it less prone to deformation or damage. This material selection not only improves the heat insulation effect of the insulation cotton but also enhances the reliability and durability of the entire ozone decomposition and purification device.

[0027] In summary, by sequentially arranging multiple catalytic filtration mechanisms 30, ozone is decomposed and purified in stages, effectively reducing ozone pollution to the production environment. Furthermore, the catalytic filtration mechanism 30 is detachable, facilitating replacement and maintenance, thus improving the ease of use and practicality of the device. The insulated chamber 22 effectively reduces the influence of external temperature on the temperature inside the ozone purification chamber 21, ensuring the normal operation of the catalytic filtration mechanism 30. In addition, the sealed structure effectively prevents ozone leakage, improving the purification effect of the device.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
