[0002] Styrene-butadiene rubber (SBR) drying exhaust gas is a high-temperature, high-humidity, multi-component, and complex industrial waste gas generated during the hot air drying and dehydration process of SBR production. Its main components include large amounts of water vapor, incompletely polymerized styrene and butadiene monomers, low-molecular-weight organic compounds, antioxidant decomposition products, volatile oils, and fine rubber dust. This exhaust gas is characterized by saturated humidity, high pollutant concentration, complex composition, and a tendency to form viscous aerosols. It not only has a strong odor but also poses a serious threat to the environment and human health if directly emitted, making it a typical and highly challenging waste gas to treat in the rubber industry.

[0003] For specific details regarding existing treatment devices and methods for exhaust gas from high-aromatic oil, low-filling styrene-butadiene rubber (SBR) drying ovens, please refer to the butadiene rubber drying exhaust gas treatment device disclosed in CN206980372U.

[0014] A preferred method for treating exhaust gas from a high-aromatic-oil, low-filler styrene-butadiene rubber drying oven includes the following steps: S1: Start the water pump. The water pump will transport the spray liquid inside the storage tank to the nozzle through the first connecting pipe. Then, the nozzle will spray the exhaust gas inside the first main body of the treatment device, which will cool down and reduce the particles in the exhaust gas. The spray liquid will then be transported to the second connecting pipe inside the first main body of the treatment device. After being filtered by the filter sheet inside the filter element, it will be transported to the storage tank through the connecting hose for recycling. S2: As the liquid is transported through the second connecting pipe to the interior of the filter element, it will cause the fan blade to rotate. When the fan blade rotates, it will also cause the transmission rod and cleaning brush head to rotate simultaneously. The rotating cleaning brush head will clean the surface of the filter element, and the cleaned impurities and particles will settle into the storage tube. At the same time, pressing the pressing plate will cause the pressing moving rod and the moving insert rod to move inward simultaneously. When the moving insert rod moves, it will move along the inside of the fixed sleeve rod and compress the return spring to retract until the moving insert rod is completely disengaged from the positioning groove of the fixed plate. Then, the pressing plate will be pulled down, causing the pressing moving rod to move downward along the inside of the positioning groove. At the same time, the bottom plate and the insert block will move downward. The movement of the insert block will also cause the sealing ring to move until it is completely disengaged from the inside of the storage tube. S3: When the movable rod moves, it will drive the guide slider to move along the inside of the guide groove. At the same time, when the base plate moves downward, it will drive the second fixed block and the positioning rod to move downward at the same time. When the positioning rod moves, it will move along the inside of the third fixed block until it is completely disengaged.

[0015] The advantages of this invention are: 1. This invention achieves the function of cooling exhaust gas through the structural design of the spray recovery filtration mechanism. It solves the problem that existing devices do not have components for spray cooling. If the exhaust gas temperature is high and it enters the condenser directly without cooling treatment, the heat load will be too large, the energy consumption will increase sharply, and the total energy consumption of the system will increase. This invention reduces energy consumption. 2. Through the structural design of the spray recovery filtration mechanism, this invention realizes the function of spraying waste gas to reduce rubber particles. It solves the problem that if there is no spraying component, the waste gas contains a large number of rubber particles, and if no auxiliary treatment is performed, it will lead to an increased load on the subsequent treatment device, thereby reducing the rubber particles in the waste gas. 3. Through the structural design of the spray recovery filtration mechanism, this invention enables the cleaning of the filter sheet, solving the problem that if no auxiliary cleaning component is provided, the filter sheet is prone to clogging during long-term spray recovery, thus preventing the spray liquid from being recovered into the storage tank, thereby reducing clogging.

A fixed sleeve 23 is fitted on the outside of the rotating block 22, and the rotating block 22 is rotatably connected to the fixed sleeve 23. The outside of the fixed sleeve 23 is connected to the inside of the second connecting tube 13. The storage tube 24 is fixedly connected to the bottom plate 25. The top of the bottom plate 25 is fixedly connected to the bottom of the insertion block 26. Two sets of sealing rings 27 are fixedly connected to the outside of the insertion block 26.

One end of the fixed sleeve rod 29 is fixedly connected to the return spring 36, and the other end of the return spring 36 is fixedly connected to the movable insertion rod 30.The storage tube 24 is also fixedly connected to the front and rear ends of the tube near the bottom with a fixing plate 31. The fixing plate 31 is provided with a positioning groove 34 near the bottom. The other end of the moving rod 30 is inserted into the positioning groove 34 and the moving rod 30 is slidably connected to the positioning groove 34. The fixing plate 31 is provided with a limiting groove 35 near the bottom. The limiting groove 35 and the positioning groove 34 are interconnected. The other end of the moving rod 30 is fixedly connected to one end of the pressing moving rod 32. The other end of the pressing moving rod 32 is fixedly connected to the pressing plate 33. The limiting groove 35 is sleeved on the outside of the pressing moving rod 32 and the limiting groove 35 is slidably connected to the pressing moving rod 32. During operation, the water pump 10 is started. When the water pump 10 starts, the spray liquid inside the storage tank 42 is drawn into the first connecting pipe 11 through the third connecting pipe 43. The spray liquid is then transported to the nozzle 12 through the first connecting pipe 11. The spray liquid is then sprayed onto the exhaust gas through the nozzle 12. At the same time, cooling and particle reduction in the exhaust gas are activated. The sprayed liquid is then transported vertically through the first main body 2 and the second connecting pipe 13 to the outer body 14 of the filter element. After being filtered by the filter sheet 18 inside the outer body 14, the liquid is transported to the connecting hose 15 and finally flows back into the storage tank 42, thus achieving recycling and reducing water waste. The liquid is also transported through the second connecting pipe 13 to... During the process inside the filter element's outer body 14, the water flow will drive the fan head 19 inside the second connecting pipe 13 to rotate. When the fan head 19 rotates, it will drive the transmission rod 20 and the cleaning brush head 21 to rotate synchronously. The cleaning brush head 21 rotates in contact with the surface of the filter element 18, thereby cleaning the filter element 18 and preventing clogging. At the same time, when the transmission rod 20 rotates, it will drive the rotating block 22 to rotate along the inside of the fixed sleeve 23. The impurities and particles that are cleaned off will settle at the top of the insert block 26 inside the storage tube 24. Then, the pressing plates 33 at both ends of the bottom plate 25 will be pressed inward simultaneously. When the pressing plates 33 are pressed inward, they will drive the pressing moving rod 32 to move synchronously. During the movement of 32, it will move along the inside of the limiting slide groove 35, and push the moving insert 30 outward along the positioning groove 34 opened below the fixed plate 31 until the moving insert 30 is completely disengaged from the positioning groove 34. During the movement of the moving insert 30, it will move along the inside of the fixed sleeve 29, and at the same time, it will compress the return spring 36 inside the fixed sleeve 29 to retract, and then apply downward pulling force to the pressing plate 33. The pulling force is transmitted to the first fixed block 28 and the base plate 25, and drives the base plate 25 to move downward. When the base plate 25 moves downward, the base plate 25 will drive the insert 26 and the sealing ring 27 to move downward along the bottom end of the storage tube 24 until the insert 26 and the sealing ring 27 move downward. Once the filter element 27 is completely detached from the storage tube 24, particles and impurities inside the storage tube 24 can be discharged. The design of the sealing ring 27 enhances the sealing effect, preventing liquid leakage through gaps. When removing the filter element's outer body 14, simply rotate the nut 17 along the outside of the bolt 16 until the nut 17 is completely detached from the outside of the bolt 16. Then, pull out the bolt 16 inside the connecting hose 15 and the second connecting tube 13 to remove the filter element's outer body 14. Simultaneously, when filling the liquid storage tank 42, water will be pre-filtered through the filter box 44 before flowing into the liquid storage tank 42. The engagement between the fourth fixing block 45 and the rubber stop block 46 fixes the position of the filter box 44. When it needs to be removed...Simply pulling the filter box 44 will deform the rubber block 46 and move it upwards along the rubber block 46 until it detaches.

A method for treating exhaust gas from a high-aromatic-oil, low-filler styrene-butadiene rubber drying oven, comprising the following steps: S1: Start the water pump 10. The water pump 10 will transport the spray liquid inside the storage tank 42 to the nozzle 12 through the first connecting pipe 11. Then, the nozzle 12 will spray the exhaust gas inside the first main body 2 of the treatment device, which will cool down and reduce the particles in the exhaust gas. The spray liquid will then be transported to the second connecting pipe 13 inside the first main body 2 of the treatment device. After being filtered by the filter sheet 18 inside the filter body 14, it will be transported to the storage tank 42 through the connecting hose 15 for recycling. S2: As the liquid is transported through the second connecting pipe 13 into the body 14 of the filter element, it will drive the fan head 19 to rotate. When the fan head 19 rotates, it will drive the transmission rod 20 and the cleaning brush head 21 to rotate simultaneously. The rotation of the cleaning brush head 21 will clean the surface of the filter plate 18, and the impurities and particles after cleaning will settle into the storage tube 24. At the same time, pressing the pressing plate 33 will drive the pressing moving rod 32 and the moving insert rod 30 to move inward simultaneously. When the moving insert rod 30 moves, it will move along the inside of the fixed sleeve rod 29 and compress the return spring 36 to retract until the moving insert rod 30 is completely disengaged from the positioning groove 34 opened in the fixed plate 31. Then, the pressing plate 33 is pulled down, which will drive the pressing moving rod 32 to move downward along the inside of the positioning groove 34. At the same time, it will drive the bottom plate 25 and the insert block 26 to move downward. When the insert block 26 moves, it will drive the sealing ring 27 to move until it is completely disengaged from the inside of the storage tube 24. S3: When the movable rod 30 moves, it will drive the guide slider 37 to move along the inside of the guide groove 38. At the same time, when the base plate 25 moves downward, it will drive the second fixed block 39 and the positioning rod 40 to move downward at the same time. When the positioning rod 40 moves, it will move along the inside of the third fixed block 41 until it is completely disengaged. During operation, the movable rod 30 moves, which will drive the guide slider 37 to move along the inside of the guide groove 38. The cooperation between the guide slider 37 and the guide groove 38 can effectively prevent the movable rod 30 from rotating, thus increasing stability. When the base plate 25 moves downward, it will drive the second fixing block 39 and the positioning rod 40 to move downward simultaneously. When the positioning rod 40 moves, it will move downward along the inside of the third fixing block 41 until it is completely disengaged.
