Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and in particular to a solid waste pyrolysis gasification device under emergency conditions. Background Technology

[0002] Solid waste (such as municipal solid waste, green solid waste, agricultural and forestry biomass waste, plastics, textiles, paper, etc.) undergoes high-temperature pyrolysis gasification to produce pyrolysis gas, pyrolysis oil, and pyrolysis residue. Due to the complex composition of solid waste, the pyrolysis gas produced by pyrolysis gasification also has a very complex composition, typically containing dust particles, NOx, SO2, HCl, H2O, H2, CH4, CO, CO2, dioxins, etc. The pyrolysis gas needs to be treated to meet the pollution control standards for municipal solid waste incineration and other relevant laws and regulations before being released into the atmosphere. A complete system of solid waste pyrolysis gasification furnace and exhaust gas treatment is generally installed in a fixed indoor space with a stable supply of water, electricity, and gas, and sufficient installation space and time. However, in emergency situations such as natural disasters, war, or other situations lacking public facilities, using pyrolysis gasification technology to treat solid waste faces new challenges and technical difficulties, such as how to achieve the desired solid waste treatment effect while installing the equipment in a container for rapid transportation and deployment. Summary of the Invention

[0003] This invention provides a solid waste pyrolysis gasification device for emergency conditions, which solves the problem that existing equipment cannot simultaneously achieve good solid waste treatment effect and rapid transportation and use.

[0004] This invention provides a solid waste pyrolysis gasification device under emergency conditions, comprising a container, a pusher box and a pyrolysis gasification tank connected to the pusher box, a feed hopper between the pusher box and the top of the container, a garbage bin elevator at the feed hopper, the garbage bin elevator being used to lift garbage bins and pour the solid waste inside the garbage bins into the feed hopper, a pusher mechanism being provided at the end of the pusher box away from the pyrolysis gasification tank, an inclined pressing mechanism being connected to the pusher box between the pyrolysis gasification tank and the feed hopper, a slag-breaking mechanism for breaking up solid waste being provided on the pyrolysis gasification tank, the exhaust gas outlet of the pyrolysis gasification tank being connected to a first combustion tank, and the exhaust gas outlet of the first combustion tank being connected to a second combustion tank.

[0005] Preferably, the pyrolysis gasification tank is provided with a jacket on the outside, the exhaust gas outlet of the second combustion tank is connected to the jacket, and the outlet of the jacket is connected to the heat exchanger.

[0006] Preferably, the slag breaking mechanism is located below the pusher box, and the jacket is located between the pusher box and the slag breaking mechanism.

[0007] Preferably, the slag breaking mechanism includes: a slag breaking knife, a slag breaking shaft, a telescopic rod, and a drive motor. An isolation box is fixed on the pyrolysis gasification tank. A telescopic rod is fixed between the drive motor and the isolation box. One end of the slag breaking shaft is fixed to the drive motor. The other end of the slag breaking shaft passes through the isolation box and the tank wall of the pyrolysis gasification tank and is fixed to the slag breaking knife. A roller is rotatably provided at the bottom of the drive motor.

[0008] Preferably, the heat exchanger includes a heat exchange chamber, and a heat exchange plate with a cooling chamber is provided inside the heat exchange chamber. The heat exchange plate divides the heat exchange chamber into an air inlet chamber and an air outlet chamber. The heat exchange plate is provided with multiple cooling channels that connect the air inlet chamber and the air outlet chamber. The cooling channels penetrate the cooling chamber. An inlet water pipe and an outlet water pipe that communicate with the cooling chamber are connected to the heat exchange plate. An air inlet pipe and an air outlet pipe are respectively connected to the air inlet chamber and the air outlet chamber.

[0009] Preferably, the pushing mechanism includes a pusher, the bottom of which is provided with a pulley capable of rolling along the pushing box, and the pushing box is provided with a pushing cylinder for driving the pusher to move.

[0010] Preferably, the pressing mechanism includes a pressing box that is tilted and fixed on a pushing box, a pressing device that is slidably arranged inside the pressing box, and a pressing cylinder that is fixed to the pressing box. The lower end of the pressing box is a pressing surface, and the pressing surface is arranged parallel to the pushing cylinder.

[0011] Preferably, a slag discharge mechanism is provided below the slag breaking mechanism. The slag discharge mechanism includes a discharge box located below the pyrolysis gasification tank. The discharge box extends toward the slag discharge door of the container. The slag discharge door is located at the rear end of the container. The discharge box is connected to the slag discharge port at the bottom of the pyrolysis gasification tank. A slag pusher is provided inside the discharge box. The slag pusher is connected to a slag pushing cylinder for pushing its movement.

[0012] Preferably, it also includes a protective cover, wherein the pyrolysis gasification tank, the first combustion tank and the second combustion tank are all located inside the protective cover, and the heat exchanger is located on the container wall near the protective cover.

[0013] Preferably, the first combustion tank is provided with an oxygen supply pipe, which includes an arc-shaped section, a first vertical section and a second vertical section. The arc-shaped section is located between the first vertical section and the second vertical section, and the lower end of the second vertical section is curved.

[0014] Compared with the prior art, in this invention, a garbage bin filled with solid waste is placed on a garbage bin elevator, which then lifts the solid waste to the top of a container and pours it into a feeding hopper. A pushing mechanism pushes the solid waste to the discharge end of the pushing box. When the pushing mechanism returns, a pressing mechanism presses the solid waste obliquely downwards, thereby preventing the exhaust gas from the pyrolysis gasification tank from escaping from the pushing box. When the pressing mechanism returns, the pushing mechanism pushes new solid waste to the discharge end of the pushing box and pushes some of the pressed solid waste into the pyrolysis gasification tank. As the pressed solid waste falls downwards, it is broken up by a slag breaking mechanism, allowing the solid waste to fully contact the combustion air, thereby improving the combustion efficiency of the solid waste in the pyrolysis gasification tank. Solid waste undergoes drying, pyrolysis, reduction, and combustion sequentially in the pyrolysis gasification tank. A burner at the bottom of the pyrolysis gasification tank provides energy for combustion. The gas produced in the pyrolysis gasification tank is connected to the first combustion tank via a connecting pipe at the top of the tank. A burner at the top of the first combustion tank ignites the gas, which then burns. Unburned gas enters the second combustion tank via a connecting pipe and continues to burn there. This design ensures complete combustion of pyrolysis gas and tar vapor, eliminating the risk of secondary air pollution from exhaust gases. Furthermore, the height of all three tanks (pyrolysis gasification tank, first combustion tank, and second combustion tank) is less than the height of a shipping container. In this invention, the discharge end of the pusher box is connected to the top of the pyrolysis gasification tank, resulting in limited space between the pusher box and the top of the container. The problem of feeding the pyrolysis gasification tank into the container is solved by placing the feed hopper on top of the container and using a garbage bin elevator to transport the solid waste. The combined action of the pushing and pressing mechanisms compresses the solid waste and delivers it into the pyrolysis gasification tank. A breaking mechanism then disperses the solid waste, resolving the issue of exhaust gas leakage within the pyrolysis gasification tank and ensuring sufficient contact between the solid waste and combustion air, thus guaranteeing optimal combustion efficiency. The pushing and pressing mechanisms, along with their inclined design, allow for installation within the limited space between the pushing box and the top of the container. The three-tank design ensures effective solid waste treatment while allowing for installation within the container. This structural combination ensures effective solid waste treatment while enabling the solid waste pyrolysis gasification unit to be installed within the container, resulting in a compact overall structure that facilitates rapid transportation and deployment.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0027] See attached document Figure 1This invention provides a solid waste pyrolysis gasification device under emergency conditions, including a container 1. The container 1 contains a pusher box 2 and a pyrolysis gasification tank 3 connected to the pusher box 2. A feed hopper 04 is located between the pusher box 2 and the top of the container 1, with the feed inlet of the feed hopper 04 protruding from the container 1. A garbage bin elevator 5 is located at the feed hopper 04 in the container 1. The garbage bin elevator 5 is used to lift the garbage bins and pour the solid waste inside into the feed hopper 04. (See attached figure.) Figure 3 The pusher box 2 is equipped with a pusher mechanism 6 at the end away from the pyrolysis gasification tank 3. An inclined pressing mechanism 7 is connected to the pusher box 2 between the pyrolysis gasification tank 3 and the feed hopper 04. The lower end of the pressing mechanism 7 is close to the pyrolysis gasification tank 3. The pyrolysis gasification tank 3 is equipped with a slag-breaking mechanism 8 for breaking up solid waste. (Refer to Appendix) Figure 2The exhaust gas outlet of the pyrolysis gasification tank 3 is connected to the first combustion tank 01, and the exhaust gas outlet of the first combustion tank 01 is connected to the second combustion tank 02. The pyrolysis gasification tank 3, the first combustion tank 01, and the second combustion tank 02 are all vertically installed inside the container 1. In this invention, a garbage bin filled with solid waste is placed on a garbage bin elevator 5. The garbage bin elevator 5 then lifts the solid waste to the top of the container 1 and pours it into the feed hopper 04. The pushing mechanism 6 pushes the solid waste to the discharge end of the pushing box 2. When the pushing mechanism 6 returns, the pressing mechanism 7 presses the solid waste downward at an angle. The compacted solid waste seals the inlet of the pyrolysis gasification tank 3, thereby preventing the exhaust gas of the pyrolysis gasification tank 3 from escaping from the pushing box 2. When the pressing mechanism 7 returns, the pressing mechanism 6 pushes new solid waste to the discharge end of the pushing box 2 and pushes some of the compacted solid waste into the pyrolysis gasification tank 3. As the compacted solid waste falls downward, it is broken up by the slag breaking mechanism 8, allowing the solid waste to fully contact the combustion air, thereby improving the combustion efficiency of the solid waste in the pyrolysis gasification tank 3. Solid waste undergoes drying, pyrolysis, reduction, and combustion processes sequentially in the pyrolysis gasification tank 3. A burner at the bottom of the pyrolysis gasification tank 3 provides energy for combustion. The gas produced by the pyrolysis gasification tank 3 is connected to the first combustion tank 01 via a connecting pipe at the top of the tank. The burner at the top of the first combustion tank 01 ignites the gas, which then burns in the first combustion tank 01. Unburned gas enters the second combustion tank 02 via a connecting pipe and continues to burn in the second combustion tank 02. This design ensures complete combustion of pyrolysis gas and tar vapor, eliminating the risk of dioxins and secondary air pollution from exhaust gases. Furthermore, the height of all three tanks (pyrolysis gasification tank 3, first combustion tank 01, and second combustion tank 02) is less than the height of the container 1. In this invention, the discharge end of the pusher box 2 is connected to the upper end of the pyrolysis gasification tank 3, resulting in limited space between the pusher box 2 and the top of the container 1. The problem of feeding the pyrolysis gasification tank 3 into the container 1 is solved by placing the feed hopper 04 on the top of the container 1 and using a garbage bin elevator 5 to transport solid waste. The pushing mechanism 6 and the pressing mechanism 7 work together to compress the solid waste and deliver it into the pyrolysis gasification tank 3. Then, the slag-breaking mechanism 8 breaks up the solid waste, solving the problem of tail gas leakage within the pyrolysis gasification tank 3 and ensuring sufficient contact between the solid waste and the combustion air, thus guaranteeing the combustion effect. The pushing mechanism 6 and the inclined pressing mechanism 7 allow it to be installed in the limited space between the pushing box 2 and the top of the container 1. The three-tank design ensures both effective solid waste treatment and allows the tanks to be installed inside the container 1. Through the coordination of the above structures, the solid waste pyrolysis gasification device can be installed inside the container 1 while ensuring effective solid waste treatment, achieving the goals of rapid transportation and rapid deployment.

[0028] Specifically, the height of the second combustion tank 02 is less than the height of the first combustion tank 01, and the connecting pipe between the second combustion tank 02 and the pyrolysis gasification tank 3 is located above the second combustion tank 02. This structural design facilitates a compact overall structure.

[0029] In another embodiment of the present invention, a jacket 03 is provided on the outside of the pyrolysis gasification tank 3, the exhaust gas outlet of the second combustion tank 02 is connected to the jacket 03, and the outlet of the jacket 03 is connected to the heat exchanger 9. This structural design can fully utilize the heat energy of gas combustion in the second combustion tank 02, play a role in waste heat utilization, and help save energy and reduce consumption.

[0030] As another embodiment of the present invention: the slag breaking mechanism 8 is located below the pusher box 2, the jacket 03 is located between the pusher box 2 and the slag breaking mechanism 8, the jacket 03 surrounds the middle position of the pyrolysis gasification tank 3, the slag breaking mechanism 8 is connected to the lower end of the pyrolysis gasification tank 3, and the slag discharge mechanism 4 is located below the pyrolysis gasification tank 3. This structural design makes the overall structure compact.

[0031] One embodiment of the slag breaking mechanism 8: The slag breaking mechanism 8 includes: a slag breaking knife 81, a slag breaking shaft 82, a telescopic rod 83, and a drive motor 84. An isolation box 86 is fixed on the pyrolysis gasification tank 3. A telescopic rod 83 is fixed between the drive motor 84 and the isolation box 86. One end of the slag breaking shaft 82 is fixed to the output shaft of the drive motor 84. The other end of the slag breaking shaft 82 passes through the isolation box 86 and the tank wall of the pyrolysis gasification tank 3 and is fixed to the slag breaking knife 81. There is a gap between the slag breaking shaft 82, the isolation box 86, and the pyrolysis gasification tank 3. The heat from the pyrolysis gasification tank 3 comes out along the gap, passes through the isolation box 86, and then leaks to the outside. The isolation box 86 can slow down the heat loss. A roller 85 is rotatably provided at the bottom of the drive motor 84. The slag breaking shaft 82 can rotate inside the pyrolysis gasification tank 3 and can move along its axial direction inside the pyrolysis gasification tank 3. Specifically, the telescopic rod 83 is a hydraulic drive rod. The drive motor 84 drives the slag-breaking shaft 82 to rotate, causing the slag-breaking blade 81 to break up the falling solid waste. The telescopic rod 83 extends and retracts, causing the roller 85 of the drive motor 84 to roll along the support. The drive motor 84 moves, causing the slag-breaking blade 81 to move back and forth along the axial direction of the slag-breaking shaft 82 inside the pyrolysis gasification tank 3. The slag-breaking blade 81 continuously hollows out and stirs the solid waste, thereby effectively improving the dispersing effect of the solid waste. After completion, the slag-breaking blade 81 moves to the tank wall of the pyrolysis gasification tank 3, occupying little space.

[0032] Specifically, the slag breaking shaft 82 is located between the two telescopic rods 83.

[0033] The pusher box 2 is mounted on the bracket, the drive motor 84 is fixed to the base, the rollers 85 on the base roll along the bracket, and the telescopic rod 83 is fixed between the base and the isolation box 86.

[0034] One embodiment of heat exchanger 9: Refer to the appendix Figure 5The heat exchanger 9 includes a heat exchange chamber, and a heat exchange plate 91 with a cooling chamber 911 is provided inside the heat exchange chamber. The heat exchange plate 91 divides the heat exchange chamber into an air inlet chamber 92 and an air outlet chamber 93. The heat exchange plate 91 is provided with multiple cooling channels 94 that connect the air inlet chamber 92 and the air outlet chamber 93. The cooling channels 94 penetrate the cooling chamber 911. A water inlet pipe 95 and a water outlet pipe 96 that communicate with the cooling chamber 911 are connected to the heat exchange plate 91. The air inlet chamber 92 and the air outlet chamber 93 are respectively connected to an air inlet pipe 97 and an air outlet pipe 98. The air inlet pipe 97 is connected to the outlet of the jacket 03, and the air outlet pipe 98 is connected to the exhaust gas treatment system. With this structural design, the exhaust gas in the intake chamber 92 can only reach the exhaust chamber 93 along the cooling channel 94. The cooling water in the cooling chamber 911 cools the exhaust gas in each cooling channel 94. Through this structural design, large clumps of exhaust gas are evenly separated for cooling, thereby ensuring that exhaust gas above 500°C can be cooled to below 200°C within 1 second, preventing the regeneration of dioxins.

[0035] One implementation of the feeding mechanism 6: Refer to the attached document. Figure 4 The pushing mechanism 6 includes a pusher 61 located in the pushing box 2. The bottom of the pusher 61 is provided with a pulley 62 that can roll along the pushing box 2. The pushing box 2 is provided with a pushing cylinder 63 for driving the pusher 61 to move. Specifically, the piston rod of the pushing cylinder 63 is fixed to the pusher 61.

[0036] One embodiment of the pressing mechanism 7: The pressing mechanism 7 includes a pressing box 71 that is inclinedly fixed on the push box 2. A pressing device 72 is slidably arranged inside the pressing box 71. The pressing device 72 enters the push box 2 at an angle downward. A pressing cylinder 73 that is fixed to the pressing box 71 is also installed on the pressing box 71. The lower end of the pressing box 71 is the pressing surface. The pressing surface is arranged parallel to the push cylinder 63. The pressing surface is inclined downward to compact the solid waste. The compacted solid waste at the front end of the push box 2 can effectively seal the feed port of the pyrolysis gasification tank 3.

[0037] One embodiment of the slag discharge mechanism 4: The slag discharge mechanism 4 includes a discharge box 41 disposed below the pyrolysis gasification tank 3. The discharge box 41 extends toward the slag discharge door 11 of the container 1. The slag discharge door 11 is located at the rear end of the container 1. The discharge box 41 communicates with the slag discharge port at the bottom of the pyrolysis gasification tank 3. A slag pusher 42 is provided inside the discharge box 41. The slag pusher 42 is connected to a slag pushing cylinder 43 for pushing it. Specifically, the pyrolysis gasification tank 3, the first combustion tank 01, and the second combustion tank 02 are all fixed on the mounting base. The discharge box 41 is located below the mounting base, and the piston rod of the slag pushing cylinder 43 is fixed to the slag pusher 42.

[0038] As another embodiment of the present invention: This embodiment also includes a protective cover 05. The pyrolysis gasification tank 3, the first combustion tank 01 and the second combustion tank 02 are all located inside the protective cover 05. The heat exchanger 9 is located on the wall of the container 1 near the protective cover 05. The protective cover 05 is fixed on the mounting base. Through this structural design, the distance between the jacket 03 and the heat exchanger 9 is short, and the exhaust gas in the jacket 03 can be quickly discharged into the heat exchanger 9 for rapid cooling.

[0039] One implementation of the trash can lifting machine 5: Refer to the attached document. Figure 6 and attached Figure 7 The garbage bin lifting machine 5 includes a lifting frame 52, on which a lifting motor 53 is installed. The lifting motor 53 drives the bottom plate 51 on the lifting frame 52 to rise and fall. The garbage bin is mounted on the bottom plate 51 and then lifted above the container 1 by the lifting motor 53. The top of the lifting frame 52 is arc-shaped. When the bottom plate 51 carrying the garbage bin reaches the arc-shaped top of the lifting frame 52, it overturns and the garbage in the garbage bin is poured into the feed hopper 04.

[0040] As another embodiment of the present invention: refer to the appendix Figure 8 The oxygen supply pipe 06 is located inside the first combustion tank 01. Specifically, the oxygen supply pipe 06 includes an arc-shaped section, a first vertical section, and a second vertical section. The arc-shaped section is located between the first and second vertical sections, and the lower end of the second vertical section is curved. This design can extend the residence time of air in the first combustion tank 01. The high-temperature gas in the first combustion tank 01 preheats the air in the oxygen supply pipe, thereby improving combustion efficiency and saving energy.

[0041] In another embodiment of the present invention: the pusher box 2 is located in the middle of the container 1, the pyrolysis gasification tank 3 is located at the rear end of the container 1, the cooling tower 07 is located at the front end of the container 1 and in front of the pusher box 2, the heat exchanger 9 is connected to the cooling tower 07, the water tank 08 is connected to the cooling tower 07, the water tank 08 is located near the cooling tower 07 and also near the pusher box 2, and is distributed on the same side as the heat exchanger 9; the hot water from the heat exchanger 9 can be cooled by the water cooling tower or used for domestic purposes, thus saving energy and reducing consumption.

[0042] In another embodiment of the present invention: the oxygen supply fan 09 and the hydraulic station 010 are both located near the push box 2.
