Description

Technical Field

[0001] This invention relates to the field of solid waste harmless treatment technology, specifically to a solid waste harmless treatment device based on pyrolysis technology. Background Technology

[0002] The harmless treatment of solid waste refers to the process of properly treating or disposing of solid waste or its harmful components to prevent them from harming the environment, or to transforming them into substances harmless to the environment. Common methods include landfilling, incineration, composting, dismantling, and chemical methods. With the acceleration of urbanization and population growth, the amount of solid waste generated is increasing dramatically. Traditional solid waste treatment methods, such as landfilling and incineration, have many drawbacks. Landfilling not only occupies a large amount of land resources but may also lead to soil and groundwater pollution; incineration produces harmful gases such as dioxins, causing serious air pollution.

[0003] Therefore, Chinese Patent Publication No. CN 119216344 A proposes a solid waste harmless treatment device based on pyrolysis technology, including a processing frame. A pyrolysis positioning cylinder is fixedly installed at the bottom of the processing frame, and a hydraulic push rod is inserted and fixedly installed at the upper part of the processing frame. A compaction and diversion component is fixedly connected to the extended end of the hydraulic push rod. The compaction and diversion component includes a filter compaction frame fixedly connected to the extended end of the hydraulic push rod. This facilitates the separation of adsorbed sludge and waste liquid from the compacted solid waste during the compaction process in sanitary landfill, avoiding the presence of elastic voids after compaction due to the mixing of internal sludge and waste liquid. This increases the storage and compaction capacity and prevents other waste from affecting the loading and compaction efficiency when adding solid waste, ensuring the overall efficiency and quality of sanitary landfill.

[0004] However, when this solid waste harmless treatment device based on pyrolysis technology is in use, it cannot ensure that the solid waste being pyrolyzed comes into full contact with the high-temperature gas, resulting in low pyrolysis efficiency and the inability to treat the gas generated during pyrolysis, thus causing defects in the use of the device.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-8This invention provides a technical solution: a solid waste harmless treatment device based on pyrolysis technology, including a pyrolysis furnace 1. The pyrolysis furnace 1 has a heating wire 2 inside, which heats the interior of the furnace 1. A furnace plate 3 is slidably connected inside the furnace 1, with its outer side fitting against the inner wall of the furnace 1. The furnace plate 3 moves up and down and rotates along the inner wall of the furnace 1. A storage box 4 is detachably connected to the top of the furnace plate 3, and the top of the furnace plate 3 is threadedly connected to the storage box 4. A through hole 5 is opened on one side of the furnace plate 3, allowing circulation within the pyrolysis furnace 1. A conveying pipe 40 is fixedly connected inside the pyrolysis furnace 1. The crushed waste enters the storage box 4 through the conveying pipe 40. A conveying box 39 is fixedly connected to the end of the conveying pipe 40 away from the pyrolysis furnace 1. The conveying box 39 includes a conveying rod, spiral blades, a drive motor, and a box body. The drive motor drives the spiral blades to rotate via the conveying rod. The rotating blades feed the crushed waste into the box body, and then through the conveying pipe 4... The solid waste enters the storage box 4 in the pyrolysis furnace 1. A crushing box 33 is fixedly connected to the bottom of the conveying box 39. A fourth rotating rod 36 is symmetrically rotatably connected inside the crushing box 33. A crushing roller 35 is fixedly connected to the outside of the fourth rotating rod 36. The rotation of the fourth rotating rod 36 causes the crushing roller 35 to rotate, crushing the solid waste with a small volume, increasing the contact area with the high temperature gas, and improving the pyrolysis efficiency. A first connecting pipe 7 is fixedly connected to the top of the pyrolysis furnace 1. A cyclone separator 8 is fixedly connected to the end of the first connecting pipe 7 away from the pyrolysis furnace 1. The gas after pyrolysis in the pyrolysis furnace 1 enters the cyclone separator 8 through the first connecting pipe 7. The cyclone separator 8 separates the solid particles in the pyrolysis gas. A second connecting pipe 9 is fixedly connected to the top of the cyclone separator 8. A spray tower 10 is fixedly connected to the end of the second connecting pipe 9 away from the cyclone separator 8. The separated gas enters the interior of the spray tower 10 through the second connecting pipe 9. The spray tower 10 sprays the pyrolysis gas.

[0033] Furthermore, a partition plate 6 is fixedly connected inside the pyrolysis furnace 1. A turntable 20 is rotatably connected to the top of the partition plate 6. Hollow rods 16 are symmetrically fixedly connected to the top of the turntable 20. The rotation of the turntable 20 causes the hollow rods 16 to rotate. A first connecting rod 15 is slidably connected inside the hollow rod 16. The first connecting rod 15 moves along the inside of the hollow rod 16. The rotation of the hollow rod 16 causes the first connecting rod 15 to rotate. The top of the first connecting rod 15 is fixedly connected to the furnace plate 3. The rotation or movement of the first connecting rod 15 causes the furnace plate 3 to rotate or move.

[0034] Furthermore, a connecting frame 18 is fixedly connected to the top of the turntable 20, and a sleeve rod 17 is slidably connected inside the connecting frame 18. The top of the sleeve rod 17 is fixedly connected to the furnace plate 3, and the movement of the sleeve rod 17 moves the furnace plate 3.

[0035] Furthermore, a connecting ring 32 is fixedly connected to the bottom of the turntable 20. The rotation of the connecting ring 32 causes the turntable 20 to rotate. The bottom of the connecting ring 32 passes through the bottom of the partition 6 and is fixedly connected to a large pulley 21. The rotation of the large pulley 21 causes the connecting ring 32 to rotate. The interior of the pyrolysis furnace 1 is rotatably connected to a first rotating rod 24. A small pulley 22 is fixedly connected to the outer top of the first rotating rod 24. The rotation of the first rotating rod 24 causes the small pulley 22 to rotate. The small pulley 22 is connected to the large pulley 21 through a transmission belt 23. The small pulley 22 drives the large pulley 21 to rotate through the transmission belt 23.

[0036] Furthermore, an inlet 34 is fixedly connected to the top of the crushing box 33. Waste is poured into the crushing box 33 through the inlet 34. The inlet 34 is inclined so that the solid waste can fall better between the two sets of crushing rollers 35 for crushing. A dust collection box 41 is fixedly connected to the bottom of the cyclone separator 8 to collect the separated solid particles for better subsequent processing. A door panel 42 is hinged to one side of the pyrolysis furnace 1 to access the storage box 4 inside the pyrolysis furnace 1 for convenient centralized processing of the decomposed solid residue in the storage box 4.

[0037] Furthermore, a rotating plate 25 is fixedly connected to the bottom outer side of the first rotating rod 24. The rotation of the first rotating rod 24 causes the rotating plate 25 to rotate. Multiple gear teeth 26 are provided on one side of the rotating plate 25, causing the gear teeth 26 to rotate. An arc-shaped connecting plate 27 is fixedly connected to the side of the rotating plate 25 away from the gear teeth 26, causing the arc-shaped connecting plate 27 to rotate. A connecting column 30 is fixedly connected to the top of the arc-shaped connecting plate 27, causing the connecting column 30 to rotate. A sector gear 28 is rotatably connected inside the pyrolysis furnace 1. A second connecting rod 29 is fixedly connected to one side of the sector gear 28. When 30 moves to one side of the second connecting rod 29, it drives the sector gear 28 to rotate via the second connecting rod 29. One side of the sector gear 28 meshes with the gear teeth 26. When the rotating plate 25 and the sector gear 28 rotate, allowing the gear teeth 26 to mesh with the toothed side of the sector gear 28, the rotating plate 25 continues to drive the sector gear 28 to rotate. When the gear teeth 26 leave one side of the sector gear 28, the arc-shaped connecting plate 27 continues to rotate against the toothless side of the sector gear 28. At this time, the sector gear 28 returns to a stationary state. Therefore, the rotating plate 25 drives the sector gear 28 to rotate intermittently with the cooperation of the gear teeth 26 and the arc-shaped connecting plate 27.

[0038] Furthermore, a second motor 43 is fixedly connected inside the pyrolysis furnace 1. The output end of the second motor 43 is fixedly connected to the first rotating rod 24. After the second motor 43 is turned on, it drives the first rotating rod 24 to rotate.

[0039] Furthermore, a reciprocating screw 19 is fixedly connected to the center of one side of the sector gear 28. The rotation of the sector gear 28 causes the reciprocating screw 19 to rotate intermittently. The top of the reciprocating screw 19 passes through one side of the turntable 20. The outer side of the reciprocating screw 19 does not contact the connecting ring 32, the large pulley 21, or the turntable 20. The outer side of the reciprocating screw 19 is threadedly connected to the sleeve rod 17. The rotation of the reciprocating screw 19 causes the sleeve rod 17 to move, so that the storage box 4 rotates inside the pyrolysis furnace 1 while moving up and down intermittently.

[0040] Furthermore, an outlet 11 is fixedly connected to the top of the spray tower 10, allowing the treated gas to leave the interior of the spray tower 10 through the outlet 11. A spray pipe 12 is fixedly connected inside the spray tower 10, into which the spray liquid is introduced. Multiple nozzles 13 are provided on the outside of the spray pipe 12, which spray the liquid in the spray pipe 12 to spray the pyrolysis gas. An activated carbon plate 14 is fixedly connected inside the spray tower 10 and above the spray pipe 12, which adsorbs the residual organic pollutants in the pyrolysis gas.

[0041] Furthermore, a first motor 37 is fixedly connected to one side of the crushing box 33. Two sets of fourth rotating rods 36 are provided. One end of each set of fourth rotating rods 36 passes through one side of the crushing box 33 and is fixedly connected to a first gear 38. There are two sets of first gears 38, which mesh with each other. With the cooperation of the first gears 38, the two sets of fourth rotating rods 36 rotate simultaneously. One set of fourth rotating rods 36 passes through one side of the crushing box 33 and is fixedly connected to the output end of the first motor 37. After the first motor 37 is turned on, it drives one set of fourth rotating rods 36 to rotate, causing the two sets of first gears 38 to rotate simultaneously.

[0042] In operation, the first motor 37, heating wire 2, second motor 43, cyclone separator 8, and nozzle 13 are turned on. The first motor 37 drives a set of fourth rotating rods 36 and first gears 38 to rotate. The two sets of first gears 38 work together to drive two sets of crushing rollers 35 through the fourth rotating rods 36. Waste is fed in from the inlet 34, and the crushing rollers 35 crush the waste. The waste is then conveyed through the conveyor box 39 and conveyor pipe 40 to the storage box 4 in the pyrolysis furnace 1. The second motor 43 drives the first rotating rod 24 to rotate. The first rotating rod 24 drives the small pulley 22 and rotating plate 25 to rotate. 22 rotates via the transmission belt 23, which drives the large pulley 21 to rotate. The large pulley 21 drives the connecting ring 32 to rotate, which in turn drives the turntable 20 to rotate. The rotation of the turntable 20, through the hollow rod 16 and the first connecting rod 15, drives the furnace plate 3 to rotate. The rotation of the furnace plate 3, in turn, drives the storage box 4 to rotate. When the rotating plate 25 rotates, the toothless side of the arc-shaped connecting plate 27 and the sector gear 28 rotate. At this time, the sector gear 28 does not rotate. When the connecting column 30 rotates to the side of the second connecting rod 29, the connecting column 30 drives the sector gear 28 to rotate through the second connecting rod 29. The sector gear 28 meshes with the gear tooth 26 on one side, and the rotating plate 25 continues to rotate the sector gear 28 through the gear tooth 26. When the gear tooth 26 leaves one side of the sector gear 28, the arc-shaped connecting plate 27 continues to rotate against the toothless side of the sector gear 28. At this time, the sector gear 28 returns to a stationary state. Therefore, the rotating plate 25 rotates the sector gear 28 intermittently under the cooperation of the gear tooth 26 and the arc-shaped connecting plate 27. The rotation of the sector gear 28 drives the reciprocating screw 19 to rotate, the rotation of the reciprocating screw 19 drives the sleeve rod 17 to move, and the sleeve rod 17 drives the furnace plate 3 and the storage box 4 to move. The position of the storage box 4 is adjusted so that it rotates inside the pyrolysis furnace 1 and moves up and down intermittently, so that the crushed waste comes into full contact with the high-temperature gas inside the pyrolysis furnace 1 to achieve pyrolysis. The gas during pyrolysis enters the cyclone separator 8 through the first connecting pipe 7. The cyclone separator 8 removes solid particles from the pyrolysis gas. The nozzle 13 sprays the alkaline solution in the spray pipe 12 to wash the pyrolysis gas and remove the acidic gas. After washing, the gas continues to move upward, and the activated carbon plate 14 adsorbs the residual organic pollutants in the pyrolysis gas, so that the purified gas meets the emission standards.
