[0002] Activated carbon carbonization equipment is a device that heats and decomposes carbon-containing raw materials in an oxygen-free or low-oxygen environment to produce carbonized materials, laying the foundation for subsequent activation processes. Activated carbon carbonization equipment with tail gas recovery function can effectively improve energy utilization and reduce environmental pollution by collecting, treating, and reusing tail gas.

[0003] Existing activated carbon carbonization devices with exhaust gas recovery mostly directly recover and reuse exhaust gas to achieve combustion-aiding effects. However, such direct utilization may result in a large amount of impurities and tar in the exhaust gas, causing secondary pollution. Therefore, we propose an activated carbon carbonization device with exhaust gas recovery function. Utility Model Content

The bottom of the sealing sleeve is fixedly connected to the drive motor, and the output end of the drive motor is eccentrically connected to the rotating plate inside the sealing sleeve. The top of the rotating plate is fixedly connected to a scraper that contacts the outer wall of the filter screen.

[0009] Furthermore, the impurity cleaning mechanism also includes a fixing block and a support ball.

Detailed Implementation

[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 protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: an activated carbon carbonization device with exhaust gas recovery function, including a carbonization box 1 and a combustion chamber 2. The combustion chamber 2 is provided at the bottom of the carbonization box 1, and a top discharge pipe 3 is provided at the top of the carbonization box 1. The top of the top discharge pipe 3 is fixedly connected to a circulation mechanism 4 that allows the exhaust gas to be circulated into the combustion chamber 2. A filtration treatment mechanism 5 for removing impurities from the exhaust gas is provided outside the circulation mechanism 4, and an impurity cleaning mechanism 6 for preventing impurities from clogging is provided inside the filtration treatment mechanism 5.

[0019] The circulation mechanism 4 can recycle the exhaust gas back into the combustion chamber 2, achieving the effect of combustion-supporting exhaust gas recovery. Then, when the exhaust gas is recycled through the circulation mechanism 4, it can be filtered by the filtration mechanism 5 to remove large impurities, thereby preventing large impurities from affecting the normal operation of the circulation mechanism 4. The impurity cleaning mechanism 6 can prevent large impurities from adhering to the inside of the filtration mechanism 5 and affecting the normal circulation and transportation of the exhaust gas.

[0020] Please see Figures 1-2 The circulation mechanism 4 includes an induced draft fan 7, a circulation pipe 8, a condenser 9, and a three-way valve 10. An induced draft fan 7 is installed at the top of the top discharge pipe 3. One end of the induced draft fan 7 is fixedly connected to a filter treatment mechanism 5. The other side of the filter treatment mechanism 5 is fixedly connected to the circulation pipe 8 through the condenser 9. The end of the circulation pipe 8 away from the condenser 9 extends into the combustion chamber 2. A three-way valve 10 is installed on the outside of the circulation pipe 8.

[0021] The exhaust fan 7 can extract and transport the exhaust gas into the combustion chamber 2, while the condenser 9 can separate liquid byproducts such as tar and wood vinegar. The three-way valve 10 can connect to the external exhaust gas treatment mechanism to treat and discharge the exhaust gas when combustion begins.

[0022] Please see Figures 1-3The filtration mechanism 5 includes a connecting sleeve 11, an air inlet pipe 12, a filter screen 13, an air outlet pipe 14, a sealing sleeve 15, and a threaded connecting pipe 16. One side of the connecting sleeve 11 is fixedly connected to the air inlet pipe 12, which is connected to the air outlet of the induced draft fan 7. The filter screen 13 is provided inside the connecting sleeve 11. The other side of the connecting sleeve 11 is provided with an air outlet pipe 14 that penetrates into the filter screen 13. One end of the air outlet pipe 14 is connected to the condenser 9. The sealing sleeve 15 is provided outside the filter screen 13. The top of the sealing sleeve 15 is fixedly connected to the threaded connecting pipe 16, which is threadedly connected to the connecting sleeve 11.

[0023] When the exhaust gas that needs to be circulated is transported by the induced draft fan 7, it enters between the connecting sleeve 11 and the sealing sleeve 15 through the air inlet pipe 12. Large impurities can be filtered through the filter screen 13. The filtered exhaust gas can be circulated and discharged through the air outlet pipe 14 that extends into the filter screen 13. The sealing sleeve 15 is connected to the connecting sleeve 11 through the threaded connecting pipe 16. This configuration makes it easy to remove the sealing sleeve 15 to clean and maintain the filter screen 13.

[0024] Please see Figures 1-4 The impurity cleaning mechanism 6 includes a drive motor 17, a rotating plate 18, and a scraper 19. The bottom of the sealing sleeve 15 is fixedly connected to the drive motor 17. The output end of the drive motor 17 and located inside the sealing sleeve 15 are eccentrically connected to the rotating plate 18. The top of the rotating plate 18 is fixedly connected to the scraper 19, which contacts the outer wall of the filter screen 13. The impurity cleaning mechanism 6 also includes a fixing block 20 and a support ball 21. One end of the scraper 19 is fixedly connected to multiple sets of fixing blocks 20. One side of the fixing block 20 is rotatably connected to the support ball 21, which contacts the inner wall of the sealing sleeve 15.

[0025] During exhaust gas recirculation, the drive motor 17 drives the rotating plate 18 and scraper 19 to rotate. This allows the scraper 19 to contact the outer wall of the filter screen 13 to scrape away impurities, preventing large pieces of impurities from adhering to the filter screen 13 and affecting normal use. Subsequently, when the scraper 19 rotates and scrapes, the support ball bearing 21 can support the back of the scraper 19 to prevent the scraper 19 from shifting position when scraping the filter screen 13.

[0026] In operation, the circulation mechanism 4 first recycles the exhaust gas back into the combustion chamber 2, achieving the effect of combustion-supporting exhaust gas recovery. Then, as the exhaust gas circulates through the circulation mechanism 4, it passes through the filtration mechanism 5 to remove large impurities, preventing them from affecting the normal operation of the circulation mechanism 4. The impurity cleaning mechanism 6 prevents large impurities from adhering to the filtration mechanism 5 and affecting the normal circulation and delivery of the exhaust gas. The induced draft fan 7 draws the exhaust gas into the combustion chamber 2, while the condenser 9 separates liquid byproducts such as tar and wood vinegar. Finally, the three-way valve 10 connects to an external exhaust gas treatment mechanism at the start of combustion for exhaust gas treatment and discharge. When the exhaust gas needs to be circulated, it passes through the induced draft fan 7... The intake pipe 12 enters between the connecting sleeve 11 and the sealing sleeve 15, and can filter large impurities through the filter screen 13. The filtered exhaust gas can be circulated and discharged through the exhaust pipe 14 extending into the filter screen 13. The sealing sleeve 15 is connected to the connecting sleeve 11 through the threaded connecting pipe 16. This setting makes it easy to remove the sealing sleeve 15 for cleaning and maintenance of the filter screen 13. During exhaust gas circulation, the drive motor 17 drives the rotating plate 18 and the scraper 19 to rotate. This allows the scraper 19 to contact the outer wall of the filter screen 13 to scrape away impurities, preventing large impurities from adhering to the filter screen 13 and affecting normal use. Subsequently, when the scraper 19 rotates and scrapes, the back of the scraper 19 can be supported by the support ball 21 to prevent the scraper 19 from shifting position when scraping the filter screen 13.
