[0002] Exhaust gas treatment devices are a type of environmental protection equipment used for purification. Their core function is to remove particulate matter from exhaust gas through physical, chemical, or biological means, so that exhaust gas emissions meet national or industry environmental protection standards.

[0003] The core working logic of the exhaust gas treatment device is to use a modular synergy of "pretreatment, core reaction, and posttreatment" to remove different types of pollutants in the exhaust gas through physical interception, catalytic conversion, chemical absorption or reduction, and finally achieve emission standards.

[0004] However, existing exhaust gas treatment devices only focus on purifying pollutants and do not effectively utilize the large amount of waste heat carried by the treated exhaust gas. The high-temperature exhaust gas after treatment is directly emitted to the outside, which easily leads to serious energy waste. In the workshop production operation, it is often necessary to maintain a certain ambient temperature or preheat some production materials. This process requires the use of additional heating equipment and preheating devices, which increases the energy consumption and operating costs of the workshop. Therefore, an exhaust gas treatment device with waste heat recovery function is proposed to address the above problems. Summary of the Invention

[0017] 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 scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figure 1-4 As shown, a waste gas treatment device with waste heat recovery function includes a main body 1. An inlet pipe 11 is installed at one end of the main body 1, and an outlet pipe 12 is installed at the other end. Two mounting rings 13 are fixedly connected to the top of the outlet pipe 12. A support cylinder 14 is installed on the inner wall of the two mounting rings 13, and a fixing frame 15 is fixedly connected to the outer wall of the support cylinder 14. An exhaust fan 16 is installed in the middle of the fixing frame 15. During operation, the main body 1 is the core carrier for waste gas treatment. The inlet pipe 11 at its end serves as the input channel for the waste gas to be treated. The waste gas first enters the main body 1 through the inlet pipe 11, where it undergoes basic treatment processes. The treated exhaust gas still carries a large amount of residual heat and is discharged outward from the exhaust pipe 12 installed at the other end of the main body 1. The exhaust fan 16 in the middle of the fixed frame 15 is started. The exhaust fan 16 rotates and absorbs the flue gas at the top of the exhaust pipe 12. Using the guiding effect of the fan blades, this flue gas carrying residual heat is directed to the area in the workshop that needs heat replenishment. This step solves the problem of energy waste caused by the direct discharge of residual heat after exhaust gas treatment to the outside world. At the same time, it makes up for the lack of additional energy required by the workshop to maintain the heat demand. It not only realizes the recovery and secondary utilization of exhaust gas residual heat, but also significantly improves the energy recycling rate of the production system and reduces the energy consumption investment of auxiliary heating and material preheating equipment in the workshop.

[0020] like Figure 1-4As shown, the outer wall of the support cylinder 14 has a toothed groove 2. The support cylinder 14 is rotatably connected to two mounting rings 13. A fixing plate 21 is fixedly connected to the top of the equipment body 1. The fixing plate 21 is located near the toothed groove 2. A limiting groove 22 is formed at the top of the toothed groove 2. An mounting block 23 is fixedly connected to the top of the equipment body 1. A telescopic rod 24 is installed inside the mounting block 23. A toothed rail 25 is fixedly connected to the output end of the telescopic rod 24. The toothed rail 25 is slidably connected to the limiting groove 22. The side wall of the toothed rail 25 is engaged with the toothed groove 2. When in operation, the telescopic rod 24 reciprocates, causing the toothed rail 25 at its output end to slide along the limiting groove 22 on the outer wall of the support cylinder 14. Since the toothed rail 25 meshes with the toothed groove 2 on the outer wall of the support cylinder 14, the support cylinder 14 will rotate within the two mounting rings 13 at the top of the exhaust pipe 12 as the toothed rail 25 moves, thereby driving the exhaust fan 16 on the fixed frame 15 to adjust its rotation angle. This step solves the problem of a single waste heat delivery area, enabling the exhaust fan 16 to frequently adjust its angle and evenly deliver hot air into the workshop, thus improving the coverage of waste heat utilization.

[0021] like Figure 1-4 As shown, two frames 3 are fixed to the outer wall of the support cylinder 14. A first connecting plate 31 is inserted into the inner wall of the frame 3. The first connecting plate 31 has a U-shaped structure. A support member 32 is fixed to the end of the first connecting plate 31. Scrapers 33 are provided on both sides of the support member 32. The scrapers 33 are in contact with the inner wall of the exhaust pipe 12. During operation, when the support cylinder 14 rotates, the two frames 3 fixed to its outer wall rotate synchronously. The first connecting plate 31 inside the frame 3 drives the support member 32 to rotate. The scrapers 33 on both sides of the support member 32 contact the inner wall of the exhaust pipe 12 and scrape away impurities on the inner wall of the exhaust pipe 12 as the support member 32 rotates. This step solves the problem of impurities accumulating on the inner wall of the exhaust pipe 12 affecting the exhaust gas emission efficiency. By scraping away impurities in real time by the scrapers 33, the unobstructed flow of the exhaust pipe 12 is ensured.

[0022] like Figure 1-4 As shown, a connecting column 4 is fixedly connected to the bottom of the support member 32, and a storage box 41 is fixedly connected to the bottom of the connecting column 4. During operation, when the impurities scraped off by the scraper 33 fall, the storage box 41 below the connecting column 4 at the bottom of the support member 32 will catch the impurities. Subsequently, the first connecting plate 31 inside the frame 3 can be removed to clean the impurities in the storage box 41. This step solves the problem of scraped impurities scattering and polluting the equipment or workshop, realizes the centralized collection of impurities, and facilitates the unified treatment of impurities in the future.

[0023] like Figure 1-4As shown, a second connecting plate 5 is fixedly connected to the outer wall of the fixed frame 15, and a temperature sensor 51 is fixedly connected to the middle of the second connecting plate 5. The temperature sensor 51 is located at the top of the exhaust pipe 12. A control module is installed on the top of the main body 1 of the equipment. The exhaust fan 16 and the telescopic rod 24 are both electrically connected to the control module. The temperature sensor 51 is electrically connected to the control module. During operation, the temperature sensor 51 on the second connecting plate 5 on the outer wall of the fixed frame 15 senses the temperature of the exhaust gas and transmits the temperature signal to the control module on the top of the main body 1 of the equipment. When the temperature reaches the set value, the control module automatically starts the telescopic rod 24 and the exhaust fan 16. This step solves the problem that the waste heat recovery system cannot intelligently start and stop according to the flue gas temperature, realizes the automated control of the system, reduces unnecessary energy consumption, and improves the intelligence level of the equipment.

[0024] like Figure 1-4 As shown, a reinforcing frame 6 is fixedly connected to the outer wall of the main body 1 of the equipment. The top of the reinforcing frame 6 is fixedly connected to the end of the toothed rail 25. During operation, the top of the reinforcing frame 6 fixedly connected to the outer wall of the main body 1 is fixedly connected to the end of the toothed rail 25, providing support for the extended part of the toothed rail 25. This step solves the problem that the extended part of the toothed rail 25 is prone to deformation due to uneven force, ensuring the structural stability of the toothed rail 25 and avoiding its deformation from affecting the meshing transmission with the tooth groove 2.

[0025] Working principle: The main body 1 of the equipment is the core carrier for exhaust gas treatment. The inlet pipe 11 installed at its end is the input channel for the exhaust gas to be treated. The exhaust gas first enters the main body 1 through the inlet pipe 11 and completes the basic treatment process inside the main body 1. The treated exhaust gas still carries a lot of residual heat and is discharged outward from the outlet pipe 12 installed at the other end of the main body 1. The exhaust fan 16 in the middle of the fixed frame 15 is started. The exhaust fan 16 rotates and absorbs the flue gas at the top of the outlet pipe 12. Using the guiding effect of the fan blades, this flue gas carrying residual heat is directionally transported to the area in the workshop that needs heat replenishment. The telescopic rod 24 reciprocates, driving the toothed rail 25 at its output end to slide along the limiting groove 22 on the outer wall of the support cylinder 14. Since the toothed rail 25 meshes with the toothed groove 2 on the outer wall of the support cylinder 14, the support cylinder 14 will rotate in the two mounting rings 13 at the top of the outlet pipe 12 with the movement of the toothed rail 25, thereby driving the exhaust fan 16 on the fixed frame 15. 6. Adjust the rotation angle. When the support cylinder 14 rotates, the two frames 3 fixed to its outer wall rotate synchronously. The first connecting plate 31 inside the frame 3 drives the support member 32 to rotate. The scrapers 33 on both sides of the support member 32 contact the inner wall of the exhaust pipe 12. As the support member 32 rotates, it scrapes away the impurities on the inner wall of the exhaust pipe 12. When the impurities scraped by the scraper 33 fall, the collection box 41 below the bottom connecting column 4 of the support member 32 will catch the impurities. Afterwards, the first connecting plate 31 inside the frame 3 can be removed to clean the impurities in the collection box 41. The temperature sensor 51 on the second connecting plate 5 on the outer wall of the fixed frame 15 senses the temperature of the exhaust gas and transmits the temperature signal to the control module on the top of the main body 1. When the temperature reaches the set value, the control module automatically starts the telescopic rod 24 and the exhaust fan 16. The top of the reinforcing frame 6 fixed to the outer wall of the main body 1 is fixedly connected to the end of the toothed rail 25 to provide support for the part of the toothed rail 25 extending outward.
