It mainly utilizes the role of a catalyst to catalytically oxidize organic pollutants in waste gas into carbon dioxide and water at a relatively low temperature, thereby achieving the purpose of purifying the waste gas. Catalytic combustion of waste gas has the advantages of high purification efficiency, low energy consumption, stable operation, and wide applicability, and is one of the commonly used technologies in industrial waste gas treatment.

An exhaust pipe is connected to the outer wall of the exhaust component. A dust suppression component is provided at the top of the exhaust component. The dust suppression component includes a water pump, a water tank, a drain cover, and nozzles. The water pump is located at the top of the exhaust component, and the water tank is located at the top of the water pump. By activating the water pump of the dust suppression component, water is drawn from the water tank and delivered to the drain cover and nozzles.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a waste gas catalytic combustion treatment device, including a support leg 1, a catalytic burner body 2 mounted on the surface of the support leg 1, an inlet pipe 3 connected to the surface of the catalytic burner body 2, and an exhaust pipe 4 connected to the surface of the catalytic burner body 2. The exhaust pipe 4 is T-shaped and has a recovery structure 5 on its surface. By setting the recovery structure 5, the heat of the high-temperature waste gas is transferred to the water in the recovery pipe 53, raising the water temperature and realizing waste heat recovery. The heated water can be used for other production processes or domestic purposes, improving energy utilization efficiency and reducing heat waste. The surface of the support leg 1 is provided with a heat insulation structure 6. By setting the heat insulation structure 6, the heat insulation cotton 65 can tightly wrap the exhaust pipe 4, effectively reducing the heat loss from the exhaust pipe 4 to the surrounding environment, reducing energy loss during equipment operation, and improving the overall energy utilization efficiency of the equipment.

[0031] Reference Figure 2and Figure 3 and Figure 4 As shown in this embodiment, the recovery structure 5 includes two recovery chambers 51, which are respectively connected to both ends of the exhaust pipe 4. An exhaust pipe 52 is connected to the surface of each recovery chamber 51, and several recovery pipes 53 are fixedly connected to the inner wall of each chamber. Each recovery pipe 53 is connected to an inlet chamber 54 and an outlet chamber 55, respectively. Connecting pipes 56 are connected to the surfaces of both the inlet and outlet chambers 54 and 55. By connecting numerous recovery pipes 53 through a unified inlet and outlet chamber 54, water can flow orderly within each recovery pipe 53, absorbing heat from the exhaust gas. This not only improves heat exchange efficiency but also concentrates and recovers dispersed heat for reuse, providing a large amount of hot water or thermal energy for other processes, enhancing equipment energy utilization, and reducing operating costs. Several sealing rings 57, made of rubber, are fixedly connected to the arc surface of the connecting pipe 56. The sealing rings 57 ensure the sealing of the connecting pipe 56 when connected to other components, preventing leakage during water circulation and ensuring the stable operation of the recovery structure 5. This avoids water waste and equipment damage caused by leakage. Several baffles 58 are fixedly connected to the inner wall of the recovery chamber 51. The baffles 58 extend the residence time of the waste gas in the recovery chamber 51, allowing for more sufficient heat exchange time between the waste gas and the recovery pipe 53. This allows for more efficient heat transfer to the water in the recovery pipe 53, further enhancing the waste heat recovery effect.

[0032] Reference Figure 5 As shown, specifically, the insulation structure 6 includes a bracket 61, which is fixedly connected to the surface of the support leg 1. A bidirectional screw 62 is rotatably connected to the surface of the bracket 61, and two drive arms 63 are threadedly connected to the surface of the bidirectional screw 62. The two drive arms 63 are located on both sides of the bracket 61, and a protective cover 64 is fixedly connected to the end of each drive arm 63 near the exhaust pipe 4. Insulation cotton 65 is glued to the inner wall of the protective cover 64. A guide rod 66 slides through the surface of the drive arm 63 and is fixedly connected to the bracket 61. The guide rod 66 provides a stable guide for the movement of the drive arm 63, allowing the drive arm 63 to slide smoothly under the drive of the bidirectional screw 62, preventing the drive arm 63 from shaking or deviating during movement, and ensuring that the protective cover 64 can accurately move to the predetermined position and stably insulate the exhaust pipe 4. A turntable 67 is fixedly connected to the surface of the bidirectional screw 62. The vertical cross section of the turntable 67 is in the shape of a cross. The turntable 67 is convenient for operators to rotate by hand or tool, which can more easily and accurately control the rotation of the bidirectional screw 62, thereby flexibly adjusting the position of the protective cover 64 to meet the heat preservation requirements of the exhaust pipe 4 under different working conditions.

[0033] Working principle: When this waste gas catalytic combustion treatment equipment is working, the waste gas to be treated is first input into the catalytic burner body 2 through the inlet pipe 3. Inside the catalytic burner body 2, the organic pollutants in the waste gas are catalytically oxidized into carbon dioxide and water at a relatively low temperature using a catalyst, thus purifying the waste gas. The purified gas is discharged through the exhaust pipe 4. During the gas discharge process, the recovery structure 5 plays a role in waste heat recovery. Since the two ends of the exhaust pipe 4 are connected to the recovery chamber 51, the discharged high-temperature gas enters the recovery chamber 51. The two ends of the recovery pipe 53 in the recovery chamber 51 are connected to the inlet water chamber 54 and the outlet water chamber 55, respectively. The inlet chamber 54 and outlet chamber 55 are connected to an external water circulation system via a connecting pipe 56. The sealing ring 57 on the connecting pipe 56 ensures the airtightness of the connection and prevents water leakage. The heat of the high-temperature gas is transferred to the water in the recovery pipe 53, which raises the water temperature. The heated water flows out from the outlet chamber 55 through the connecting pipe 56 and can be used in other processes that require hot water, realizing waste heat recovery, improving energy utilization efficiency, and reducing heat waste. At the same time, the baffle 58 on the inner wall of the recovery chamber 51 can prolong the residence time of the gas in the recovery chamber 51, so that the heat can be fully transferred to the water in the recovery pipe 53, enhancing the recovery effect.

[0034] In addition, the insulation structure 6 of the equipment also plays an important role. When it is necessary to insulate the exhaust pipe 4, the turntable 67 on the bidirectional screw 62 is rotated. The vertical section of the turntable 67 is "+" shaped, which is convenient for operation. The rotation of the bidirectional screw 62 drives the two drive arms 63 connected to it by threads to slide along the guide rod 66. The guide rod 66 ensures that the drive arms 63 slide smoothly and move towards each other. The protective cover 64 fixedly connected to the end of the drive arm 63 near the exhaust pipe 4 moves accordingly. When the protective cover 64 moves to the appropriate position, the insulation cotton 65 glued to its inner wall can wrap the exhaust pipe 4, reduce the heat loss from the exhaust pipe 4 to the surrounding environment, further improve the energy utilization rate, and reduce the energy consumption of the equipment operation.
