[0029] like Figure 1-10 The energy recovery device for pyrolysis of bulk solid waste shown in the figure comprises a pyrolysis mechanism and an energy recovery mechanism, wherein the energy recovery mechanism is mounted on the pyrolysis mechanism, the pyrolysis mechanism comprises a bottom plate 1, the bottom plate 1 is fixedly placed on the ground, a furnace base 2 is fixedly mounted on the bottom plate 1, a pyrolysis furnace 3 is fixedly mounted on the furnace base 2, a burner 5 is fixedly mounted at the lower end of the pyrolysis furnace 3, the energy recovery mechanism comprises a support frame 6, the support frame 6 is fixedly mounted on the bottom plate 1, a lower end conduit 8 is fixedly mounted on the support frame 6, an intermediate interface 9 is fixedly mounted on the lower end conduit 8, a side end conduit 10 is fixedly mounted on the intermediate interface 9, and the side end conduit 10 is connected to the side end conduit 10. The pyrolysis furnace 3 is fixedly connected, an intermediate conduit 11 is fixedly installed on 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 and the storage battery 15 are connected 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 rotating plate 18 is rotatably installed on the side conduit 10, and the side rotating plate 18 and the lower connecting rod 17 are fixedly connected. The bulk solid waste is burned and heat is generated by the pyrolysis mechanism, and the energy recovery mechanism collects the heat generated by the pyrolysis mechanism and converts it into electrical energy; the pyrolysis furnace 3 is used to place the waste to be burned, and the burner 5 is used to control the ignition of the waste. The high-temperature exhaust gas generated by the burned waste is often accompanied by incompletely burned oily substances, which are vaporized into a gaseous state during combustion. The exhaust gas enters the side end conduit 10 through the upper end of the pyrolysis furnace 3, and then enters the middle interface 9 through the side end conduit 10, and then enters the middle conduit 11, and then enters the high-temperature airbag 12 through the middle conduit 11. The high-temperature gas entering the high-temperature airbag 12 gradually increases, and the high-temperature airbag 12 expands, and the high-temperature airbag 12 expands and squeezes the thermoelectric converter 14. The thermoelectric converter 14 directly contacts the high-temperature airbag 12 to absorb the high-temperature airbag 12 The heat of the gas is converted into electrical energy, which enters the storage battery 15 to complete energy recovery. During the expansion process of the high-temperature airbag 12, the thermoelectric converter 14 is pushed. The movement of the thermoelectric converter 14 drives the upper connecting rod 16 to rotate, the upper connecting rod 16 drives the lower connecting rod 17 to rotate, and the lower connecting rod 17 drives the side rotating plate 18 to rotate. The side rotating plate 18 blocks the side conduit 10, thereby closing the connection between the middle interface 9 and the pyrolysis furnace 3. The gas in the pyrolysis furnace 3 can no longer enter the middle interface 9, thereby realizing automatic regulation of the gas entry amount. When the gas in the high-temperature airbag 12 is discharged 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 rotating plate 18 rotates and resets, and the exhaust gas in the pyrolysis furnace 3 can enter the high-temperature airbag 12 again.

[0030] A push cylinder 19 is fixedly installed on the support frame 6, and a lifting rack 20 is fixedly installed on the telescopic end of the push cylinder 19. A slide plate 21 is fixedly installed on the support frame 6, and the lifting rack 20 is slidably installed on the slide plate 21. A lower end guide tube 8 is fixedly installed at the lower end of the intermediate interface 9, and a lower end gear 22 is rotatably installed on the lower end guide tube 8. A lower end rotating plate 23 is fixedly installed on the lower end gear 22, and the lower end rotating plate 23 and the lifting rack 20 form a gear rack match, and an intermediate gear 24 is rotatably installed on the intermediate guide tube 11, and an intermediate rotating plate 25 is fixedly installed on the intermediate gear 24. The gear 24 forms a gear match with the lifting rack 20, and an upper gear 26 is rotatably installed on the upper end conduit 13, and an upper turn plate 27 is fixedly installed on the upper end gear 26. The lower turn plate 23, the middle turn plate 25, and the upper turn plate 27 are respectively arranged in the lower end conduit 8, the middle conduit 11 and the upper end conduit 13. The turn plate is used to close or connect the corresponding through conduits. When the lower turn plate 23 and the upper turn plate 27 are in a vertical state, the middle turn plate 25 is in a horizontal state, and an oil pipe 7 is fixedly installed at the lower end of the lower end conduit 8, and the other end of the oil pipe 7 is fixedly connected to the burner 5. When the gas enters the high-temperature airbag 12 to transfer heat to the thermoelectric converter 14, the gas in the high-temperature airbag 12 needs to be sealed first. 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 gas in the high-temperature airbag 12 is full, 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, and the oily gas After cooling, it will liquefy into oil and flow from the high-temperature airbag 12 to the middle interface 9. When the gas in the high-temperature airbag 12 is cooled, the electric cylinder 19 is pushed to work and push the lifting rack 20. The lifting rack 20 rises and drives the lower turn plate 23, the middle turn plate 25, and the upper turn plate 27 to rotate. At this time, the upper turn plate 27 and the lower turn plate 23 are in an open state, and the middle turn plate 25 is in a closed state. The oil in the middle interface 9 enters the oil pipe 7 through the lower end conduit 8 under the action of gravity, and then enters the burner 5 through the oil pipe 7 to be burned again, which reduces the oil and gas discharged into the air while reducing energy consumption and realizing oil recovery.
