DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example

[0036] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The present embodiment provides a solid waste oxygen-free thermal decomposition incineration system, comprising: a bearing base 1; a thermal decomposition chamber shell 35, the thermal decomposition chamber shell 35 is mounted on the bearing base 1, and a thermal decomposition chamber 12 is provided in the thermal decomposition chamber shell 35; at least one hanging assembly 21, the hanging assembly 21 comprises a plurality of hanging parts 22, the plurality of hanging parts 22 are mounted around the surface wall of the thermal decomposition chamber 12, there is a gap between two adjacent hanging parts 22, and the hanging parts 22 are provided with a plurality of hanging ports 23 along the extension direction; a plurality of heat storage pipes 20, the plurality of heat storage pipes 20 are distributed around the inside of the thermal decomposition chamber 12, and the plurality of heat storage pipes 20 correspond to the plurality of hanging ports 23 one by one; a feeding assembly 15, the feeding assembly 15 is connected to one end of the thermal decomposition chamber shell 35, and the feeding assembly 15 is used to provide raw materials into the thermal decomposition chamber 12; a discharging assembly 16, the discharging assembly 16 is connected to the other end of the thermal decomposition chamber shell 35, and the discharging assembly 16 is used to discharge the raw materials in the thermal decomposition chamber 12.

[0037] In this embodiment, the anaerobic thermal decomposition technology is different from the traditional high-temperature combustion process, and almost no oxygen is required in the reaction process. Such a process not only greatly reduces fuel consumption and greenhouse gas emissions, but also fundamentally reduces the harmful byproducts that may be generated during conventional waste incineration, such as dioxins, sulfur dioxide, nitrogen oxides, heavy metal vapors and other toxic substances. The bearing base 1 is installed on the foundation ground, the thermal decomposition chamber shell 35 can be cylindrical, the bearing base 1 is installed with a feed assembly 15, the feed assembly 15 is located at one end of the thermal decomposition chamber shell 35, and the bearing base 1 is installed with a discharge assembly 16, which is located at the other end of the thermal decomposition chamber shell 35; the raw material is input into the thermal decomposition chamber 12 through the feed assembly 15, and a plurality of heat storage pipes 20 are distributed around the inside of the thermal decomposition chamber 12. The plurality of heat storage pipes 20 are arranged around to ensure that each part of the raw material is evenly heated, thereby achieving an efficient heat transfer effect. After the pyrolysis of the raw material is completed, it is discharged from the thermal decomposition chamber 12 through the discharge assembly 16. Specifically, the hanging assembly 21 can be composed of four hanging parts 22, and the four hanging parts 22 can form a circular structure, and there are gaps reserved between the four hanging parts 22. Twenty heat storage tubes 20 can be distributed in the thermal decomposition chamber 12, and the twenty heat storage tubes 20 are distributed around the thermal decomposition chamber 12. Each heat storage tube 20 extends from one end of the thermal decomposition chamber 12 to the other end of the thermal decomposition chamber 12, so that it can act on the raw materials at various positions in the thermal decomposition chamber 12. The hanging part 22 can be provided with five hanging ports 23 along the arc path, and the hanging part 22 can fix five heat storage tubes 20. The four hanging parts 22 of the same hanging assembly 21 can fix the twenty heat storage tubes 20 in the thermal decomposition chamber 12. Multiple hanging assemblies 21 can be installed equidistantly in the thermal decomposition chamber 12 along the extension direction. Multiple hanging assemblies 21 can fix different positions of the twenty heat storage tubes 20, and the twenty heat storage tubes 20 can be more stably installed in the thermal decomposition chamber 12. The temperature of the raw materials during thermal decomposition in the thermal decomposition chamber 12 is relatively high. When the hanging parts 22 are heated, the mean free path between the molecules increases, resulting in thermal expansion. A gap is reserved between two adjacent hanging parts 22 of the same hanging assembly 21, which avoids the problem that the two adjacent hanging parts 22 squeeze each other after the hanging parts 22 expand, resulting in damage to the hanging parts 22. Furthermore, the four hanging parts 22 of the same hanging assembly 21 have gaps between each other, which greatly reduces the space occupancy rate in the thermal decomposition chamber 12, and the raw materials are easier to circulate in the thermal decomposition chamber 12, thereby making it easier to discharge the slag after the raw materials are pyrolyzed. Furthermore, a gap is reserved between two adjacent hanging parts 22, which greatly reduces the heat absorption area of ​​the hanging assembly 21 and reduces the heat energy loss in the thermal decomposition chamber 12.

[0038] Please refer to Figure 1 , Figure 3 , Figure 8 and Fig.13Furthermore, in the present invention, a smoke collecting shell 7 having a smoke exhaust port 8 is also included; the heat storage pipe 20 is a U-shaped structure, and the heat storage pipe 20 is arranged along the extension direction inside the thermal decomposition chamber 12, one end of the heat storage pipe 20 is a heat exhaust port 24, and the other end of the heat storage pipe 20 is a heat inlet port 25, the heat exhaust port 24 penetrates the side wall of the thermal decomposition chamber shell 35, and the heat inlet port 25 penetrates one end of the thermal decomposition chamber shell 35; the smoke collecting shell 7 is installed on the thermal decomposition chamber shell 35, and a sealed cavity 17 is provided in the smoke collecting shell 7, and multiple heat exhaust ports 24 are all located in the sealed cavity 17.

[0039] In this embodiment, a plurality of U-shaped heat storage tubes 20 surround the interior of the thermal decomposition chamber 12. The U-shaped tube heat exchanger has a compact structure, occupies a relatively small space, and has a high heat exchange efficiency. A plurality of heat exhaust ports 24 are arranged along the circumference of the thermal decomposition chamber shell 35. Each heat exhaust port 24 penetrates the side wall of the thermal decomposition chamber shell 35. The smoke collection shell 7 is installed on the outer side wall of the thermal decomposition chamber shell 35. The plurality of heat exhaust ports 24 are all located in the sealed cavity 17. The smoke exhaust port 8 is connected to the sealed cavity 17. One end of the thermal decomposition chamber shell 35 is a combustion part 50, and the interior of the combustion part 50 is a combustion chamber. The combustion part 50 is provided with a plurality of combustion holes 51 connected to the combustion chamber along the circumferential direction. The end face of the combustion part 50 is connected to the heat inlet 25 of a plurality of heat storage tubes 20. When the raw material is thermally decomposed, flames can be sprayed into the plurality of combustion holes 51. After the flame enters the combustion chamber of the combustion part 50, it can reach each heat storage tube 20, so that each heat storage tube 20 can thermally decompose the raw material in the thermal decomposition chamber 12. The smoke and dust in the heat storage tube 20 enter the sealed cavity 17 through the heat exhaust port 24, and finally discharged from the smoke exhaust port 8 of the smoke collection shell 7, and the discharged smoke and dust are harmlessly treated. After the flame enters the heat storage tube 20, it can directly act on the inner wall of the heat storage tube 20, so that the heat can be quickly and evenly transferred to the raw material in the thermal decomposition chamber 12; at the same time, the emission of harmful gases is reduced.

[0040] Please refer to Figure 2 . Further, in the present invention, the thermal decomposition chamber shell 35 includes a heat-insulating shell 18 and a reaction chamber shell 19, one end of the reaction chamber shell 19 is connected to the feed assembly 15, and the other end of the reaction chamber shell 19 is connected to the discharge assembly 16, and both ends of the reaction chamber shell 19 are installed with connecting pieces 2, and the heat-insulating shell 18 is sleeved outside the reaction chamber shell 19, and both ends of the heat-insulating shell 18 are connected to the connecting pieces 2. A plurality of elastic members 38 are installed between the heat-insulating shell 18 and the reaction chamber shell 19, one end of the elastic member 38 is connected to the heat-insulating shell 18, and the other end of the elastic member 38 is connected to the reaction chamber shell 19.

[0041] In this embodiment, connectors 2 are installed on both sides of the reaction chamber shell 19, and both ends of the insulation shell 18 are connected to the connectors 2. There is a preset space distance between the reaction chamber shell 19 and the insulation shell 18. The preset space distance between the reaction chamber shell 19 and the insulation shell 18 is filled with a high-temperature resistant aluminum silicate wool module, which effectively reduces the heat conduction between the reaction chamber shell 19 and the insulation shell 18, thereby preventing heat from being directly transferred from the reaction chamber shell 19 to the insulation shell 18. It is avoided that the temperature on the surface of the insulation shell 18 is high, which damages the support device for supporting the insulation shell 18. Among them. The elastic member 38 can be a Z-shaped spring, one end of the Z-shaped spring is connected to the insulation shell 18, and the other end of the Z-shaped spring is connected to the reaction chamber shell 19. The reaction chamber shell 19 contains the thermal decomposition chamber 12. High temperature is required in the thermal decomposition chamber 12 to thermally decompose the raw materials. The high temperature of the thermal decomposition chamber 12 will cause thermal expansion of the reaction chamber shell 19. The Z-shaped spring can buffer the energy generated during the thermal expansion of the reaction chamber shell 19, thereby preventing the reaction chamber shell 19 from being damaged due to excessive stress.

[0042] Please refer to Figure 1 . Further, in the present invention, a plurality of rotating components 3 are installed on the bearing base 1 along the extension direction of the heat insulating shell 18; a plurality of rotating rings 6 are installed on the outer wall of the heat insulating shell 18 along the extension direction, and the plurality of rotating rings 6 correspond to the plurality of rotating components 3 one by one, and a driving gear 10 is installed on the outer wall of the heat insulating shell 18, and the driving gear 10 can drive the heat insulating shell 18 to rotate. The rotating component 3 includes two relatively arranged rotating brackets 4, and the two rotating brackets 4 are both rotatably installed with supporting wheels 5, and the two supporting wheels 5 are respectively located on both sides of the rotating ring 6, and the rotating ring 6 can rotatably cooperate with the two supporting wheels 5. The bearing base 1 is tilted, and the vertical height of the bearing base 1 near the feeding component 15 is H1, and the vertical height of the bearing base 1 near the discharging component 16 is H2; wherein, the vertical height of H1 is higher than the vertical height of H2.

[0043] In this embodiment, a heat insulating layer is provided on the heat insulating shell 18 to prevent the drive gear 10 and multiple rotating rings 6 on the heat insulating shell 18 from being deformed or even damaged. The multiple rotating rings 6 on the heat insulating shell 18 correspond one to one with the multiple rotating components 3. The external device can mesh with the drive gear 10, and then control the drive gear 10 to drive the heat insulating shell 18 to rotate circumferentially, and the heat insulating shell 18 drives the reaction chamber shell 19 to rotate circumferentially, so that the raw materials in the thermal decomposition chamber 12 are turned over, the heating surface of the raw materials is increased, and the thermal decomposition efficiency is improved. The two supporting wheels 5 of the same rotating component 3 can just fit into the two sides of the rotating ring 6, the axial direction of the rotating ring 6 is parallel to the axial direction of the supporting wheel 5, and the rotating ring 6 can rotate on the two supporting wheels 5, thereby driving the heat insulating shell 18 to rotate circumferentially, so that the raw materials in the thermal decomposition chamber 12 rotate, the heating surface of the raw materials is increased, and the thermal decomposition efficiency is improved. The bearing base 1 near the feed assembly 15 is higher than the bearing base 1 near the discharge assembly 16, and the height of the thermal decomposition chamber shell 35 from the feed assembly 15 to the discharge assembly 16 gradually decreases. The thermal decomposition chamber shell 35 rotates in the circumferential direction to turn the raw materials over, increase the heating surface, and improve the thermal decomposition efficiency; the raw materials will move toward the discharge assembly 16 during the turning process, thereby improving the passing rate of the raw materials in the thermal decomposition chamber 12 and avoiding the problem of raw materials being blocked in the thermal decomposition chamber 12.

[0044] Please refer to Figure 1 and Figure 7 . Further, in the present invention, the reaction chamber shell 19 includes a first reaction chamber shell 36 and a second reaction chamber shell 37, an expansion gap 39 is reserved between the first reaction chamber shell 36 and the second reaction chamber shell 37, a sealing mechanism is sleeved between the first reaction chamber shell 36 and the second reaction chamber shell 37, and the sealing mechanism can cover the expansion gap 39; the end of the first reaction chamber shell 36 away from the second reaction chamber shell 37 is rotatably connected to the discharge member 14, the first mounting plate 9 is installed on the supporting base 1, and the discharge member 14 is installed on the first mounting plate 9; the end of the second reaction chamber shell 37 away from the first reaction chamber shell 36 is rotatably connected to the feed member 13, the second mounting plate 11 is installed on the supporting base 1, and the feed member 13 is installed on the second mounting plate 11.

[0045] In this embodiment, the second mounting plate 11 is mounted beside the first reaction chamber housing 36, and one end of the first reaction chamber housing 36 away from the second reaction chamber housing 37 is connected to the discharge member 14 (the first reaction chamber housing 36 can rotate relative to the discharge member 14), the discharge member 14 is connected to the first mounting plate 9, and the discharge assembly 16 extends through the first reaction chamber housing 36 into the discharge member 14, and the discharge assembly 16 can discharge the slag in the discharge member 14. The second mounting plate 11 is mounted beside the second reaction chamber housing 37, and one end of the second reaction chamber housing 37 away from the first reaction chamber housing 36 is connected to the feed member 13 (the second reaction chamber housing 37 can rotate relative to the feed member 13), and the feed assembly 15 extends into the feed member 13, and the feed assembly 15 can feed material into the feed member 13. There is an expansion gap 39 between the first reaction chamber shell 36 and the second reaction chamber shell 37. After being heated, the first reaction chamber shell 36 and the second reaction chamber shell 37 will expand into the expansion gap 39, thereby avoiding the problem that the first reaction chamber shell 36 and the second reaction chamber shell 37 are damaged by large stress. A sealing mechanism is sleeved between the first reaction chamber shell 36 and the second reaction chamber shell 37, and the sealing mechanism can cover the expansion gap 39. The sealing mechanism is sleeved between the first reaction chamber shell 36 and the second reaction chamber shell 37, so that the raw materials can be normally transported from the second reaction chamber shell 37 to the first reaction chamber shell 36; the feeding member 13 and the second mounting plate 11 can be sealed by a fish scale sealing sheet to prevent air from entering the thermal decomposition chamber 12 and causing an explosion in the thermal decomposition chamber 12.

[0046] Please refer to Fig.11 and Fig.12For example, the sealing mechanism is composed of a locking assembly, a first sealing member 40 of a U-shaped structure and a second sealing member 41 of a U-shaped structure. The first sealing member 40 and the second sealing member 41 are buckled together to form a circular ring structure, which can be sleeved between the first reaction chamber shell 36 and the second reaction chamber shell 37 and can just cover the expansion gap 39. The two ends of the first seal 40 and the second seal 41 after being buckled are connected with multiple locking components; the locking components are composed of a locking rod 42, a limit head 43 and a return spring 44. The locking rod 42 passes through the edge of the first seal 40 and the second seal 41 after being buckled. The locking rod 42 is provided with a return spring 44. The two ends of the locking rod 42 are connected to the limit head 43, so that the first reaction chamber shell 36 and the second reaction chamber shell 37 can be locked to cover the expansion gap 39. The first seal 40 and the second seal 41 can be connected to the inner wall of the heat insulation shell 18 through a Z-shaped spring. When the first reaction chamber shell 36 and the second reaction chamber shell 37 expand radially, the return spring 44 is compressed, and the distance between the first seal 40 and the second seal 41 is increased, which can be suitable for a columnar object with a larger outer diameter, avoiding the problem of the first seal 40 and the second seal 41 being damaged by greater stress. Among them, the two ends of the locking rod 42 can be connected to the limit head 43 by threaded matching.

[0047] For example, a sealing plate 45 is installed at the connection between the first sealing member 40 and the second sealing member 41, a plurality of first sliding grooves 46 are opened on one side of the sealing plate 45, and a plurality of second sliding grooves 47 are opened on the other side of the sealing plate 45; the first sealing member 40 is installed with a plurality of first limiting members 48, and the plurality of first limiting members 48 correspond one-to-one to the plurality of first sliding grooves 46; the second sealing member 41 is installed with a plurality of second limiting members 49, and the plurality of second limiting members 49 correspond one-to-one to the plurality of second sliding grooves 47. When the first reaction chamber shell 36 and the second reaction chamber shell 37 expand radially, the first seal 40 and the second seal 41 can be relatively separated by a certain distance, the first seal 40 drives the plurality of first limit members 48 to slide in the corresponding first sliding groove 46, and the second seal 41 drives the plurality of second limit members 49 to slide in the corresponding second sliding groove 47, and the sealing plate 45 remains stationary, and the sealing plate 45 can block the gap between the first seal 40 and the second seal 41, thereby preventing the air in the heat-insulating shell 18 and the reaction chamber shell 19 from entering the thermal decomposition chamber 12 and causing combustion. Air cannot enter the thermal decomposition chamber 12, and air cannot enter between the heat-insulating shell 18 and the reaction chamber shell 19, the feed assembly 15 is sealed with the external material receiving mechanism, and the discharge assembly 16 is sealed with the external discharge mechanism, thereby ensuring the sealing of the thermal decomposition chamber 12. However, a heat-insulating cotton material is installed between the heat-insulating shell 18 and the reaction chamber shell 19. The heat-insulating principle of the heat-insulating cotton material lies in its porous loose structure. There are many tiny gas holes between the heat-insulating cotton material, which can retain a large amount of air that is not easy to flow. Therefore, the sealing plate 45 can seal the gap between the first seal 40 and the second seal 41 to prevent the air in the heat-insulating cotton material from entering the thermal decomposition chamber 12. When the material in the reaction chamber shell flows, it will not leak into the heat-insulating cotton from the gap between the first seal 40 and the second seal 41.

The discharge pipe 34 is installed on the first mounting plate 9, and the second discharge port 32 of the discharge pipe 34 is set downward. The second feed port 29 of the discharge pipe 34 extends to the discharge piece 14. The second spiral feeding body 31 can transport the slag from the second feed port 29 to the second discharge port 32.

[0050] In summary, the embodiments of the present invention provide a solid waste anaerobic thermal decomposition incineration system. The temperature of the thermal decomposition of raw materials in the thermal decomposition chamber 12 is relatively high. After the hanging parts 22 are heated, the mean free path between the molecules increases, resulting in thermal expansion. A gap is reserved between two adjacent hanging parts 22 of the same hanging assembly 21, which avoids the problem that the two adjacent hanging parts 22 squeeze each other after the hanging parts 22 expand, resulting in damage to the hanging parts 22. Furthermore, the four hanging parts 22 of the same hanging assembly 21 have gaps between each other, which greatly reduces the space occupancy rate in the thermal decomposition chamber 12, and the raw materials are easier to circulate in the thermal decomposition chamber 12, so that it is easier to discharge the slag after the raw materials are pyrolyzed. Furthermore, a gap is reserved between two adjacent hanging parts 22, which greatly reduces the heat absorption area of ​​the hanging assembly 21 and reduces the heat energy loss in the thermal decomposition chamber 12. The present invention ensures that the raw materials can be directly in full contact with the heat storage tubes on the hanging parts, thereby maximizing the thermal energy utilization rate, shortening the thermal decomposition time of the raw materials, greatly improving the output of the thermal decomposition raw materials, effectively solving the problem of thermal expansion of each component, reducing the failure rate, shortening the maintenance time, and reducing the maintenance cost.
