[0025] 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.

[0026] This utility model provides, for example Figure 1-6The device shown is a co-pyrolysis apparatus for municipal solid waste and rice husk gasification tar. It includes a high-temperature pyrolysis furnace 6 and a heat-insulating and sealing door frame 5 installed on the outer wall of the front end of the furnace 6. A rectangular window is located on the rear side of the heat-insulating and sealing door frame 5, inside the front end of the furnace 6. The high-temperature pyrolysis furnace 6 provides the high-temperature environment required for pyrolysis. The heat-insulating and sealing door frame 5 and the rectangular window on its front outer wall are used to install and seal the heat-insulating furnace door 3 and the high-temperature resistant pyrolysis inner chamber 20. The heat-insulating and sealing door frame 5 ensures the airtightness of the furnace 6, preventing heat loss and the entry of external air. A heat-insulating furnace door 3 is located at the front end of the heat-insulating and sealing door frame 5. Two switch rails 1 are symmetrically arranged on the outer wall of the bottom front end of the furnace 6. Anti-detachment sliding bases 2 are installed on the two switch rails 1 and fixed to the bottom of the heat-insulating furnace door 3. A high-temperature resistant heat-insulating door 3 is located at the rear end of the heat-insulating furnace door 3. The inner box 20 is located inside the high-temperature pyrolysis furnace 6. The height of the inner box 20 is less than the height of the heat-insulating sealing door frame 5 and the height of the rectangular window. The heat-insulating furnace door 3 can move the inner box 20 back and forth within the heat-insulating sealing door frame 5 and the rectangular window. When the heat-insulating furnace door 3 moves back and forth, the anti-detachment sliding base 2 moves back and forth simultaneously on the two switch rails 1. The heat-insulating furnace door 3 can slide back and forth on the switch rails 1 through the anti-detachment sliding base 2, which makes it easy to push the inner box 20 into or pull out of the high-temperature pyrolysis furnace 6. The rear end is connected to the inner box 20, which plays a role in sealing and protection. The inner box 20 is used to contain municipal solid waste and rice husk gasification tar. Its height is less than the height of the heat-insulating sealing door frame 5 and the rectangular window, which ensures that it can move freely within it and withstand the direct heating of the high-temperature burner 7 during the high-temperature pyrolysis process.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a high-temperature burner 7 is installed at the center of the top of the high-temperature pyrolysis furnace 6, and the high-temperature burner 7 is connected to the interior of the high-temperature pyrolysis furnace 6. The combustion flame sprayed by the high-temperature burner 7 can directly act on the high-temperature resistant pyrolysis inner box 20. An igniter 10 is installed at the rear end of the high-temperature burner 7. The high-temperature burner 7 heats the material in the high-temperature resistant pyrolysis inner box 20 by spraying the combustion flame. The igniter 10 is used to ignite the high-temperature burner 7. A flue gas purifier 8 is installed at the top of the high-temperature burner 7, and an exhaust port 9 is installed at the top of the flue gas purifier 8. The exhaust port 9 is connected to an external emission pipe. The flue gas purifier 8 can purify the flue gas generated during the pyrolysis process. The purified gas is discharged through the exhaust port 9 connected to the external emission pipe. An electrical control box 12 is installed on the outer wall of the right end of the high-temperature pyrolysis furnace 6. Multiple gas product outlets 11 are equidistantly arranged on the upper side of the electrical control box 12. The multiple gas product outlets 11 are all close to the top of the high-temperature pyrolysis furnace 6. The multiple gas product outlets 11 are all connected to the external emission pipe. The high-temperature pyrolysis furnace 6 is internally interconnected. A fan box 13 is fixed to the outer wall of the left end of the bottom of the high-temperature pyrolysis furnace 6. Air inlets are provided at both the front and rear ends of the fan box 13. An exhaust control valve A14 is provided at the center of the left end of the fan box 13. Exhaust control valves B15 are provided on both the front and rear sides of the exhaust control valve A14. Both exhaust control valves A14 and B15 are connected to the exhaust ports of the fan box 13. Multiple one-way valves B17 are provided on the upper side of the center of the outer wall of the left end of the high-temperature pyrolysis furnace 6, with two exhaust ports. Control valve B15 is connected to multiple check valves B17 via a blower pipe B16. A check valve A19 is installed at the left end of the high-temperature burner 7. The exhaust control valve A14 is connected to the check valve A19 via a blower pipe A18. The fan box 13 draws in air through the air inlet and supplies combustion air to the high-temperature burner 7 and the high-temperature pyrolysis furnace 6 via the exhaust control valves A14 and B15, respectively. Check valves A19 and B17 ensure unidirectional gas flow and prevent backflow.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when using the co-pyrolysis device for municipal solid waste and rice husk gasification tar, the municipal solid waste and rice husk gasification tar are first mixed evenly and then placed into the high-temperature resistant pyrolysis inner chamber 20. Then, the insulated furnace door 3 is pushed, causing the high-temperature resistant pyrolysis inner chamber 20 to enter the high-temperature pyrolysis furnace 6 through the rectangular window and be sealed at the front end of the insulated sealing door frame 5. At this time, the interior of the high-temperature pyrolysis furnace 6 is in a sealed environment. Then, the igniter 10 is activated, igniting the high-temperature burner 7. The combustion flame directly acts on the material in the high-temperature resistant pyrolysis inner chamber 20, providing the heat required for high-temperature pyrolysis. Under high temperature, the organic matter in municipal solid waste and rice husk gasification tar undergoes pyrolysis, decomposing into gaseous, liquid, and solid products. The gaseous products are discharged through multiple gas product outlets 11 at the top of the high-temperature pyrolysis furnace 6 for further processing and utilization. The liquid products (tar) are further decomposed or condensed and recovered at high temperature. The solid products (carbon black, etc.) remain in the high-temperature resistant pyrolysis inner chamber 20. The flue gas generated during pyrolysis is purified by a flue gas purifier 8 at the top of the high-temperature burner 7 to remove harmful substances such as dust and acidic gases. The gas is connected to the external emission pipe through exhaust port 9 and discharged into the atmosphere, while the fan box 13 draws in air through the air inlet. The opening of the exhaust control valves A14 and B15 is adjusted as needed to supply appropriate amounts of combustion air to the high-temperature burner 7 and the high-temperature pyrolysis furnace 6, respectively. One-way valves A19 and B17 ensure unidirectional gas flow and prevent backflow. Blower pipes A18 and B16 are connected to exhaust control valves A14 and A19, and exhaust control valves B15 and B17, respectively, ensuring a stable gas supply. This municipal solid waste... The co-pyrolysis device for rice husk gasification tar achieves efficient pyrolysis treatment of municipal solid waste and rice husk gasification tar through reasonable structural design and functional configuration. The high-temperature pyrolysis furnace 6 provides a high-temperature environment, the heat-insulated sealing door frame 5 and the heat-insulated furnace door 3 ensure sealing performance, the high-temperature burner 7 provides a heat source, the flue gas purifier 8 treats the flue gas, the electrical control box 12 controls the operating parameters, and the fan box 13 provides combustion air. Through the synergistic effect of these components, municipal solid waste and rice husk gasification tar can be effectively converted into useful products, achieving the goals of resource recycling and environmental protection.

[0029] like Figure 1 , Figure 3 and Figure 6As shown, a high-temperature pyrolysis inner chamber 20 is connected to the upper side of the center of the insulated furnace door 3 by an intervention pyrolysis device 4. The intervention pyrolysis device 4 includes an insulated inner cylinder 23, a fixed outer cylinder 24, and a high-temperature resistant push-pull rod 25. A perforation is connected inside the upper side of the center of the high-temperature pyrolysis inner chamber 20 and the insulated furnace door 3. The fixed outer cylinder 24 is installed outside the front end of the perforation and is fixed to the front outer wall of the insulated furnace door 3. The insulated inner cylinder 23 is fixed inside the fixed outer cylinder 24. The high-temperature resistant push-pull rod 25 is connected between the insulated inner cylinder 23 and the perforation. The rear end of the high-temperature resistant push-pull rod 25 is located at... Inside the high-temperature pyrolysis inner chamber 20, the high-temperature resistant push-pull rod 25 can move back and forth within the insulated inner cylinder 23 and the perforation. The high-temperature resistant push-pull rod 25 is one of the core components of the intervention pyrolysis device 4. Its ability to move back and forth within the insulated inner cylinder 23 and the perforation drives the high-temperature resistant integrated frame 27 and the high-temperature intervention rake rod 26 to move within the high-temperature pyrolysis inner chamber 20. By pushing the high-temperature resistant push-pull rod 25 back and forth, the material in the pyrolysis inner chamber can be stirred and turned, allowing the material to be heated more fully and improving pyrolysis efficiency. Meanwhile, the insulated inner cylinder 23 and the fixed... The outer cylinder 24 primarily serves as insulation, preventing heat from the high-temperature pyrolysis inner chamber from being conducted to the insulated furnace door 3 and the push-pull handle 21, thus protecting operators from burns. Simultaneously, it provides stable support and guidance for the high-temperature resistant push-pull rod 25, ensuring smooth forward and backward movement. The intervention pyrolysis device 4 also includes a high-temperature resistant intervention rake rod 26 and a high-temperature resistant integrated frame 27. The high-temperature resistant integrated frame 27 is fixed to the rear end of the high-temperature resistant push-pull rod 25. The high-temperature resistant integrated frame 27 is horizontally positioned inside the upper side of the center of the high-temperature pyrolysis inner chamber 20. Multiple high-temperature resistant intervention rakes 26 are equidistantly arranged at the bottom. The high-temperature resistant integrated frame 27 is fixed to the rear end of the high-temperature resistant push-pull rod 25 and is horizontally arranged inside the upper side of the center of the high-temperature pyrolysis inner box 20. The multiple high-temperature resistant intervention rakes 26 equidistantly arranged at the bottom can penetrate into the material to stir and turn it. During the pyrolysis process, the material is prone to pile up, resulting in uneven heating of some materials and insufficient pyrolysis. The function of the high-temperature resistant intervention rakes 26 is to break the pile-up state of the material, so that the material can be heated evenly, thereby improving the pyrolysis effect and quality.

[0030] like Figure 1 , Figure 3 and Figure 6As shown, the intervention pyrolysis device 4 also includes a push-pull handle 21 and a ceramic heat-insulating fixing sleeve 22. The front end of the high-temperature resistant push-pull rod 25 is located outside the front end of the heat-insulating inner cylinder 23 and the fixed outer cylinder 24. The ceramic heat-insulating fixing sleeve 22 is fixed to the front end of the high-temperature resistant push-pull rod 25. The push-pull handle 21 is connected to the outer walls of the left and right ends of the ceramic heat-insulating fixing sleeve 22. The push-pull handle 21 can drive the high-temperature resistant push-pull rod 25 to move back and forth through the ceramic heat-insulating fixing sleeve 22. The ceramic heat-insulating fixing sleeve 22 is fixed to the front end of the high-temperature resistant push-pull rod 25, and the push-pull handle 21 is connected to the outer walls of the left and right ends. The ceramic heat-insulating fixing sleeve 22 also plays a heat insulation role to prevent the operator from being burned when operating the push-pull handle 21. The design of the push-pull handle 21 allows the operator to easily push the high-temperature resistant push-pull rod 25 back and forth, thereby controlling the high-temperature intervention rake rod 26 in the high-temperature resistant... The position and movement of the pyrolysis inner chamber 20 are controlled by the push-pull handle 21. The operator can stir and turn the material in a timely manner according to the progress and needs of pyrolysis to achieve the best pyrolysis effect. After municipal solid waste and rice husk gasification tar are put into the high-temperature pyrolysis inner chamber 20, the high-temperature pyrolysis inner chamber 20 is pushed into the high-temperature pyrolysis furnace 6 and the heat-insulating furnace door 3 is sealed. During the high-temperature pyrolysis process, the operator can push the high-temperature push-pull rod 25 back and forth through the push-pull handle 21 to make the high-temperature intervention rake rod 26 move back and forth in the high-temperature pyrolysis inner chamber 20 to stir and turn the material. This allows the material to be heated more fully, avoids material accumulation, and improves pyrolysis efficiency and quality. At the same time, the heat insulation effect of the heat-insulating inner cylinder 23, the fixed outer cylinder 24 and the ceramic heat-insulating fixing sleeve 22 can protect the safety of the operator.
