[0031] Such as Figures 1-10A pyrolysis energy recovery system for solid materials as shown includes a pyrolysis mechanism and an energy recovery mechanism. The energy recovery mechanism is installed on the pyrolysis mechanism. The pyrolysis mechanism includes a bottom plate 1 which is fixedly placed on the ground. A furnace base 2 is fixedly installed on the bottom plate 1. A pyrolysis furnace 3 is fixedly installed on the furnace base 2. A burner 5 is fixedly installed at the lower end of the pyrolysis furnace 3. The energy recovery mechanism includes a support frame 6 which is fixedly installed on the bottom plate 1. A lower conduit 8 is fixedly installed on the support frame 6. An intermediate interface 9 is fixedly installed on the lower conduit 8. A side conduit 10 is fixedly installed on the intermediate interface 9. The side conduit 10 is fixedly connected to the pyrolysis furnace 3. An intermediate conduit 11 is fixedly installed at the upper end of the intermediate interface 9. A high-temperature airbag 12 is fixedly installed on the intermediate conduit 11. An upper conduit 13 is fixedly installed on the high-temperature airbag 12. A thermoelectric converter 14 is slidably installed on the support frame 6. A storage battery 15 is fixedly installed on the support frame 6. The thermoelectric converter 14 is connected to the storage battery 15 through a wire. An upper connecting rod 16 is rotatably installed on the thermoelectric converter 14. A lower connecting rod 17 is rotatably installed on the upper connecting rod 16. A side end rotating plate 18 is rotatably installed on the side conduit 10. The side end rotating plate 18 is fixedly connected to the lower connecting rod 17. The pyrolysis mechanism burns large amounts of solid waste and generates heat, and the energy recovery mechanism collects and converts the heat generated by the pyrolysis mechanism into electrical energy. The waste to be burned is placed in the pyrolysis furnace 3. The burner 5 is used to control the ignition of the waste. The high-temperature waste gas generated by the burning waste often contains unburned oily substances which vaporize into gas during combustion. The waste gas enters the side conduit 10 through the upper end of the pyrolysis furnace 3, then enters the intermediate interface 9 through the side conduit 10, then enters the intermediate conduit 11, and then enters the high-temperature airbag 12. The high-temperature gas entering the high-temperature airbag 12 gradually increases, causing the high-temperature airbag 12 to expand. The expansion of the high-temperature airbag 12 squeezes the thermoelectric converter 14. The thermoelectric converter 14 directly contacts the high-temperature airbag 12 to absorb the heat of the gas in the high-temperature airbag 12 and converts the thermal energy into electrical energy, which enters the storage battery 15 to complete energy recovery. During the expansion of the high-temperature airbag 12, it pushes the thermoelectric converter 14. The movement of the thermoelectric converter 14 drives the rotation of the upper connecting rod 16. The upper connecting rod 16 drives the rotation of the lower connecting rod 17. The lower connecting rod 17 drives the rotation of the side end rotating plate 18. The side end rotating plate 18 blocks the side conduit 10, thus closing the connection between the intermediate interface 9 and the pyrolysis furnace 3, and the gas in the pyrolysis furnace 3 cannot enter the intermediate interface 9 anymore, realizing the automatic regulation of the gas inlet volume. When the gas in the high-temperature airbag 12 is exported through the upper conduit 13, the volume of the high-temperature airbag 12 becomes smaller, the upper connecting rod 16 and the lower connecting rod 17 rotate, and the side end rotating plate 18 rotates back to its original position, and the waste gas in the pyrolysis furnace 3 can enter the high-temperature airbag 12 again.

[0032] A push electric cylinder 19 is fixedly installed on the support frame 6. The telescopic end of the push electric cylinder 19 is fixedly installed with a lifting rack 20. A chute plate 21 is fixedly installed on the support frame 6. The lifting rack 20 is slidably installed on the chute plate 21. A lower conduit 8 is fixedly installed at the lower end of the middle interface 9. A lower gear 22 is rotatably installed on the lower conduit 8. A lower rotating plate 23 is fixedly installed on the lower gear 22. The lower rotating plate 23 and the lifting rack 20 form a gear-rack fit. A middle gear 24 is rotatably installed on the middle conduit 11. A middle rotating plate 25 is fixedly installed on the middle gear 24. The middle gear 24 and the lifting rack 20 form a gear fit. An upper gear 26 is rotatably installed on the upper conduit 13. An upper rotating plate 27 is fixedly installed on the upper gear 26. The lower rotating plate 23, the middle rotating plate 25, and the upper rotating plate 27 are respectively arranged in the lower conduit 8, the middle conduit 11, and the upper conduit 13. The rotating plates are used to close or communicate with the corresponding conduits. When the lower rotating plate 23 and the upper rotating plate 27 are in a vertical state, the middle rotating plate 25 is in a horizontal state. A hydraulic tube 7 is fixedly installed at the lower end of the lower conduit 8. The other end of the hydraulic tube 7 is fixedly connected to the burner 5. When the gas enters the high-temperature airbag 12 and transfers heat to the thermoelectric converter 14, it is necessary to first seal the gas in the high-temperature airbag 12. Initially, the side rotating plate 18 and the middle rotating plate 25 are in an open state, and the lower rotating plate 23 and the upper rotating plate 27 are in a closed state. The gas enters the high-temperature airbag 12 through the side conduit 10. Since the lower rotating plate 23 and the upper rotating plate 27 are closed, the gas will not flow out from the upper and lower ends of the high-temperature airbag 12. When the high-temperature airbag 12 is filled with gas, the side rotating plate 18 is closed under the action of the lower connecting rod 17. At this time, the high-temperature airbag 12, the middle conduit 11, and the middle interface 9 form a closed space. The oily gas will liquefy into oil when cooled and flow from the high-temperature airbag 12 into the middle interface 9. When the gas in the high-temperature airbag 12 is cooled, the push electric cylinder 19 works to push the lifting rack 20. The lifting rack 20 rises to drive the lower rotating plate 23, the middle rotating plate 25, and the upper rotating plate 27 to rotate. At this time, the upper rotating plate 27 and the lower rotating plate 23 are in an open state, and the middle rotating plate 25 is in a closed state. The oil in the middle interface 9 enters the hydraulic tube 7 through the lower conduit 8 under the action of gravity, and then enters the burner 5 through the hydraulic tube 7 for combustion again, reducing the oil and gas discharged into the air while reducing the energy consumption and realizing the recovery of the oil.
