Description

Technical Field

[0001] The present invention relates to the technical field of biomass pyrolysis, particularly to pyrolysis mechanisms and biomass pyrolysis apparatuses.

Background Art

[0002] The reaction process in which a substance is decomposed by receiving heat is called pyrolysis. In an oxygen-free or low-oxygen environment, the process in which biomass is heated to raise the temperature, causing the decomposition of molecules to produce coke, condensable liquids, and gas products is called biomass pyrolysis.

[0003] The pyrolysis of biomass is always carried out by a biomass pyrolysis apparatus. Lignocellulosic biomass is an ideal raw material suitable for the pyrolysis process. Due to differences in its composition structure, biomass raw materials exhibit different pyrolysis characteristics, which has great significance for its research. However, in the research process, the biomass pyrolysis apparatus used needs to mix multiple types of materials for pyrolysis in its pyrolysis process. For example, biomass can be catalytically pyrolyzed by a catalyst, or biomass and plastic can be co-pyrolyzed by a catalyst. By combining biomass with different catalysts, the directional production of certain high-value-added chemicals can be realized. Also, biomass is an oxygen-enriched raw material, and plastic is a hydrogen-enriched raw material. The catalytic co-pyrolysis of biomass and plastic can realize the directional preparation of aromatic hydrocarbon-enriched bio-oil, etc.

[0004] In the experimental process, usually, multiple types of different materials are used and mixed, raw materials with different composition components are mixed to conduct multiple sets of experimental comparisons, and the same type of raw material is detected multiple times to improve accuracy.

[0005] A biomass pyrolysis apparatus is composed of a pyrolysis mechanism and a product transportation mechanism. Conventional pyrolysis apparatuses mix materials and continuously heat them by the pyrolysis mechanism to perform pyrolysis.

[0006] However, during the heating process, the mixing of multiple materials within the pyrolysis mechanism often becomes uneven. If the mixed substances do not react sufficiently, the selectivity of the target product after pyrolysis decreases, the content of the produced target product is reduced, the pyrolysis efficiency decreases, and the experimental data is affected.

[0007] Furthermore, the materials inside the pyrolysis mechanism need to be replaced after the reaction is complete, which reduces the efficiency of conventional material extraction and replacement methods.

[0008] Furthermore, conventional biomass pyrolysis equipment suffers from slow and insufficient heating of the pyrolysis mechanism during pyrolysis, resulting in reduced pyrolysis efficiency.

[0009] Finally, in typical pyrolysis apparatuses, only one set of data can be measured in a single measurement process. When conducting comparative experiments, it is necessary to experiment with multiple raw materials under the same conditions and record multiple sets of data. However, current experimental apparatuses only produce one set of data at a time, and it is difficult to guarantee consistent pyrolysis temperatures during repeated experimental processes, leading to errors. Similarly, in parallel experiments, errors in temperature and other factors easily increase the errors in later experimental data, resulting in inaccurate experimental results. Therefore, conventional technology needs further improvement. [Overview of the Initiative]

[Modes for carrying out the invention]

[0028] To make the above-mentioned objectives, features, and advantages of the present invention easier to understand, specific embodiments of the present invention will be described in detail below with reference to the drawings in the specification.

[0029] The following description contains a great deal of specific details to help you fully understand the present invention. However, the present invention may be carried out in other forms different from those described herein, and those skilled in the art can similarly popularize the invention without violating its scope. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Next, the terms “one embodiment” or “example” as used herein refer to specific features, configurations, or characteristics that may be included in at least one embodiment of the present invention. The phrase “in one embodiment” appearing elsewhere in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either alone or selectively.

[0031] Example 1 Referring to Figures 1 to 13, which represent a first embodiment of the present invention, this embodiment provides a thermal decomposition mechanism that can achieve the effect of uniformly mixing multiple types of materials during heating. As shown in Figures 1, 2, and 3, the thermal decomposition mechanism includes a heat soaking cylinder assembly 101 and a material deposition assembly 102 slidably provided within the heat soaking cylinder assembly 101. A grinding assembly 103 is slidably connected to the material deposition assembly 102, and a slide thrust assembly 104 is provided at the end of the grinding assembly 103, which can push the grinding assembly 103 closer to the material deposition assembly 102. In this embodiment, the heat soaking cylinder assembly 101, the crushing assembly 103, and the material deposition assembly 102 are manufactured using heat-conducting metal and are used to ensure uniform heat conduction. The material deposition assembly 102 can uniformly arrange and partition the biomass material. The crushing assembly 103 crushes and mixes the biomass material placed in the material deposition assembly 102. During the thermal decomposition process of the biomass material, the slide thrust assembly 104 applies thrust, causing the crushing assembly 103 to press the biomass material, ensuring a crushing effect. This pressing also improves the degree of contact between the biomass material and the heat soaking cylinder assembly 101, the crushing assembly 103, and the material deposition assembly 102, thereby ensuring a heat conduction effect and improving thermal decomposition performance.

[0032] Specifically, as shown in Figure 5, the crushing assembly 103 includes a heating shaft 103a slidably mounted on the material deposition assembly 102, and a pressing plate 103b mounted on the heating shaft 103a, the pressing plate 103b being provided with crushing spikes 103c. In this embodiment, the heating shaft 103a has a heating function and can rotate and slide on the material deposition assembly 102, multiple pressing plates 103b are provided and uniformly fixedly fitted to the outside of the heating shaft 103a, multiple crushing spikes 103c are uniformly provided on the lower surface of the pressing plate 103b, the heating shaft 103a can disperse and heat the raw material by rotation, for example, when mixing plastic and biomass powder and performing thermal decomposition, the crushing spikes 103c can attach fine-grained plastic, the position of the plastic changes with the rotation of the crushing spikes 103c, and as the position changes, thermal decomposition continues.

[0033] Furthermore, as shown in Figures 3 and 5, the slide thrust assembly 104 includes a push disc 104a rotatably mounted on the heating shaft 103a, and a thrust spring 104b mounted on the push disc 104a, with a sliding column 104c provided at the end of the heating shaft 103a, and the slide thrust assembly 104 further includes a rotating sleeve 104d slidably mounted on the sliding column 104c. In this embodiment, the push disc 104a is connected to the heating shaft 103a via a bearing, and the thrust spring 104b is fitted to the outside of the heating shaft 103a. The thrust spring 104b applies thrust to the push disc 104a, propelling the heating shaft 103a to drive the pressing operation of the pressing plate 103b onto the biomass material. As the biomass material decomposes, its volume decreases, and the thrust spring 104b can automatically adjust the position of the pressing plate 103b. The elasticity of the thrust spring 104b tends to push the push disc 104a away, thereby ensuring close contact between the pressing plate 103b and the biomass raw material and ensuring the decomposition reaction. Additionally, the sliding column 104c slides inside the rotating sleeve 104d as the heating shaft 103a slides, thereby maintaining the connection between the heating shaft 103a and the rotating sleeve 104d. Furthermore, in this embodiment, the sliding column 104c has a rectangular columnar structure, and a rectangular columnar groove is provided inside the rotating sleeve 104d. The sliding column 104c cannot rotate but can slide only inside the rotating sleeve 104d. By rotating the rotating sleeve 104d, the heating shaft 103a can be rotated, and further the internal pressing plate 103b can be driven to rotate, thereby enabling the mixing of the internal biomass material.

[0034] Preferably, as shown in Figures 1, 2, 3, 4, 7, 8 and 13, the heat-sensing cylinder assembly 101 includes a heat-conductive outer cylinder 101a and a heat-conductive metal ball 101b rotatably mounted on the inner wall of the heat-conductive outer cylinder 101a, to which an internal storage cylinder 101c is rotatably connected, and the heat-sensing cylinder assembly 101 further includes a closing end 101d rotatably mounted at the end of the heat-conductive outer cylinder 101a. In this embodiment, the heat-conductive outer cylinder 101a and the inner storage cylinder 101c are rotatable relative to each other, the upper end of the inner storage cylinder 101c protrudes from the upper end of the heat-conductive outer cylinder 101a, a sealing structure is provided between the outer surface of the upper end of the inner storage cylinder 101c and the inner wall of the upper end of the heat-conductive outer cylinder 101a to maintain a seal between the heat-conductive outer cylinder 101a and the inner wall of the upper end of the heat-conductive outer cylinder 101a when the heat-conductive outer cylinder 101a rotates, and rolling grooves are provided on the inner surface of the heat-conductive outer cylinder 101a and the outer surface of the inner storage cylinder for housing the heat-conductive metal balls 101b, on which the heat-conductive metal balls 101b roll. When the heat-conductive outer cylinder 101a heats up, rotating the heat-conductive outer cylinder 101a continuously changes its position relative to the inner storage cylinder 101c, and uniform heat conduction can be achieved by the heat-conductive metal ball 101b. Furthermore, a sealing structure is provided between the closed end 101d and the heat-conductive outer cylinder 101a, and the ends of the closed end 101d and the heat-conductive outer cylinder 101a that are connected to each other can rotate relative to each other. The sealing structure is used to seal the connection when the closed end 101d and the heat-conductive outer cylinder 101a rotate, and for example, a sealing bearing is used for the connection.

[0035] As explained in Figures 1, 3, 7, and 8, an exhaust pipe is provided on the surface of the closed tip 101d. In this embodiment, nanopores are uniformly provided on the surface of the internal storage cylinder 101c to allow the gas generated during thermal decomposition to escape from the internal storage cylinder 101c, and the gas generated by thermal decomposition can be sent out through the exhaust pipe. Here, as shown in Figures 1, 2 and 6, the material stacking assembly 102 includes an arc-shaped frame 102a slidably mounted on an internal storage cylinder 101c, and a barrier ring 102b mounted on the arc-shaped frame 102a, and further includes an insulating lid 102c provided at the end of the arc-shaped frame 102a, in this embodiment the arc-shaped frame 102a is an arc-shaped plate structure that can be fitted inside the internal storage cylinder 101c, and inside the internal storage cylinder 101c there is an arc-shaped frame that fits the outer surface of the arc-shaped frame 102a An arc-shaped groove into which 102a is inserted is provided, nanopores are uniformly provided on the surface of the arc-shaped frame 102a to allow gas generated during pyrolysis to escape, multiple barrier rings 102b are provided and uniformly fixed on the arc-shaped frame 102a, the inner diameter of the arc-shaped frame 102a is the same as the outer diameter of the barrier rings 102b, and the equally spaced barrier rings 102b are connected via the arc-shaped frame 102a, thereby forming multiple regions into which biomass raw materials can be placed to partition the biomass pyrolysis raw materials. Furthermore, the insulating lid 102c is made of an insulating material and may be fixedly connected to the arc-shaped frame 102a, or rotatably connected to the arc-shaped frame 102a via a bearing, and an annular gasket is provided on the inner wall of the insulating lid 102c to seal the space between the inner wall of the insulating lid 102c and the outer wall of the internal storage cylinder 101c, and a handle for lifting is provided above the insulating lid 102c so that the arc-shaped frame 102a can be easily pulled out from the internal storage cylinder 101c, and both the arc-shaped frame 102a and the barrier ring 102b are made of a thermally conductive metal so that the biomass material to be placed can be easily heated up. Furthermore, the heating shaft 103a is slidably mounted inside the barrier ring 102b and can rotate and slide inside the barrier ring 102b. The barrier rings 102b and the pressing plates 103b are spaced apart, and each of the barrier rings 102b has a corresponding pressing plate 103b. During use, the biomass raw material is placed within the space between the pressing plate 103b at the corresponding position and the barrier ring 102b.

[0036] During use, pressing one end of the sliding column 104c compresses the thrust spring 104b, causing the heating shaft 103a to slide along the inner wall of the barrier ring 102b, separating the barrier ring 102b from the pressing plate 103b. After placing the biomass material between the barrier ring 102b and the pressing plate 103b, inserting the arc-shaped frame 102a into the internal storage cylinder 101c connects the sliding column 104c to the rotating sleeve 104d. At this time, the heating shaft 103a is heated to induce thermal decomposition, and the gas generated during thermal decomposition escapes through the gap between the internal storage cylinder 101c and the thermally conductive outer cylinder 101a, enters the closed end 101d, and is discharged through the exhaust pipe. During the thermal decomposition process, the rotating sleeve 104d is rotated to drive the internal pressing plate 103b to rotate, and the crushing spikes 103c flatten and continuously scrape the biomass raw material, thereby achieving mixing of the internal biomass material.

[0037] As described above, the heating shaft 103a can, by rotating and pressing, press and concentrate the biomass material placed in the space between the pressing platen 103b and the barrier ring 102b, and can also be stirred and mixed by the crushing spikes 103c. Furthermore, by heating the pressing platen 103b with the heating shaft 103a and bringing the pressing platen 103b into close contact with the biomass material, the thermal effect received by the biomass material can be enhanced.

[0038] Example 2 Referring to Figures 1 to 13, which represent a second embodiment of the present invention, the present embodiment differs from the previous embodiment in the following respects. This embodiment provides an automatic locking assembly 105 for a pyrolysis mechanism that solves the problem of low efficiency in exchanging biomass pyrolysis raw materials. The slide thrust assembly 104 drives the rotation of the crushing assembly 103 to crush the material, and the automatic locking assembly 105 can fix the material deposit assembly 102. In this embodiment, the material deposit assembly 102 is controlled by the automatic locking assembly 105 so that it is automatically locked, thereby facilitating the placement of biomass material by the user and the removal of the material after pyrolysis is complete. As shown in Figures 1, 3, 9, 10, 11, and 12, the automatic locking assembly 105 includes a transition member 105a provided on a rotating sleeve 104d, and a sliding connecting member 105b slidably provided on the transition member 105a, on which a self-adaptive rotating member 105c provided with a female threaded sleeve 105d is slidably connected, and a return spring 105f fitted on the outside of the female threaded sleeve 105d, and the automatic locking assembly 105 further includes a male threaded sleeve 105e provided on an arc-shaped frame 102a. In this embodiment, the rotating sleeve 104d and the closing end 101d are rotatably connected, and a sealing structure is provided at the connection between them. The transition member 105a is fixedly provided on the outside of the rotating sleeve 104d and can be pushed to raise and lower the sliding connecting member 105b. By raising and lowering the sliding connecting member 105b, rotational connection or locking between it and the self-adaptive rotating member 105c can be achieved. Furthermore, during the rotation of the rotating sleeve 104d, the female threaded sleeve 105d and the male threaded sleeve 105d are connected. The screw sleeve 105e can be controlled to be threaded, thereby fixing the arc-shaped frame 102a. Here, the male screw sleeve 105e is provided at the bottom end of the arc-shaped frame 102a, and the return spring 105f is fitted to the outside of the male screw sleeve 105e and the female screw sleeve 105d, with one end of the spring in close contact with one end of the self-adaptive rotating member 105c and the other end in close contact with the bottom end of the internal storage cylinder 101c, thereby applying a downward thrust to the self-adaptive rotating member 105c.

[0039] Specifically, as shown in Figures 9, 10, and 11, the transition member 105a includes a fixed sleeve 105a-1 provided on the rotating sleeve 104d, a horizontal groove 105a-2 provided on the fixed sleeve 105a-1, and further includes a lifting groove 105a-3 provided on the fixed sleeve 105a-1. In this embodiment, the fixed sleeve 105a-1 is fixed to the outside of the rotating sleeve 104d, and the end of the horizontal groove 105a-2 and the end of the lifting groove 105a-3 are in communication with each other.

[0040] Furthermore, as shown in Figure 12, the sliding connecting member 105b includes an annular sleeve 105b-1 slidably mounted on the fixed sleeve 105a-1, and a position limiting bump 105b-2 provided on the annular sleeve 105b-1, a support 105b-3 provided on the annular sleeve 105b-1, a support collar 105b-4 provided on the support 105b-3, and the sliding connecting member 105b further includes a slide block 105b-5 provided on the support collar 105b-4. In this embodiment, the inner wall dimensions of the annular sleeve 105b-1 coincide with the outer wall dimensions of the fixed sleeve 105a-1, the position limiting bump 105b-2 is slidably mounted in the horizontal groove 105a-2 and the vertical groove 105a-3, and the annular sleeve 105b-1 and the support collar 105b-4 are coaxial.

[0041] Preferably, as shown in Figure 11, the self-adaptive rotating member 105c includes a slide sleeve 105c-1 slidably mounted on a support collar 105b-4, and an annular groove 105c-2, a descending groove 105c-3, and an ascending groove 105c-4 provided on the slide sleeve 105c-1. In this embodiment, the annular groove 105c-2 is provided in the middle of the outer wall of the slide sleeve 105c-1, and the descending groove 105c-3 and the ascending groove 105c-4 are provided above and below the annular groove 105c-2, respectively, with the ascending groove 105c-4 tending to rise and the descending groove 105c-3 tending to descend.

[0042] What needs to be explained is that, as shown in Figures 10 and 11, the annular groove 105c-2 communicates with the descending groove 105c-3 and the ascending groove 105c-4, respectively, and in this embodiment, the slide block 105b-5 is slidable inside the annular groove 105c-2, the descending groove 105c-3, and the ascending groove 105c-4.

[0043] During use, in the initial state, the position limiting bump 105b-2 is inside the horizontal groove 105a-2, and the slide block 105b-5 is at the end of the rising groove 105c-4. After the material deposition assembly 102 is inserted into the heat distribution cylinder assembly 101, the arc-shaped frame 102a can only slide up and down, and the sliding column 104c is precisely positioned and inserted into the rotating sleeve 104d. Under the action of gravity, the bottom end of the male threaded sleeve 105e is in close contact with the top end of the female threaded sleeve 105d, and at this time, rotation By driving the rotating sleeve 104d to rotate, the fixed sleeve 105a-1 is rotated, and during rotation, the position limiting bump 105b-2 slides into the lifting groove 105a-3, and guided by the lifting groove 105a-3, the slide sleeve 105c-1 tends to rise, thereby ensuring close contact between the end of the female thread sleeve 105d and the end of the male thread sleeve 105e, and the slide block 105b-5 is at the end of the lifting groove 105c-4 and cannot slide, At this time, the female threaded sleeve 105d is driven to rotate and threaded to the male threaded sleeve 105e. The threaded connection between the male threaded sleeve 105e and the female threaded sleeve 105d causes the slide sleeve 105c-1 to rise. Furthermore, the threaded connection between the male threaded sleeve 105e and the female threaded sleeve 105d restricts the upward position of the slide sleeve 105c-1. At this time, the slide block 105b-5 gradually slides downward within the upward groove 105c-4 until it moves away from the upward groove 105c-4 and enters the annular groove 105c-2. At this time, the slide block 105b-5 idles within the annular groove 105c-2, completing the threaded connection between the male threaded sleeve 105e and the female threaded sleeve 105d. This completes the fixing of the material deposition assembly 102, maintains the driving force to the heating shaft 103a, and enables continuous rotation of the heating shaft 103a.

[0044] Furthermore, when replacing the biomass raw material after the thermal decomposition is complete, when the rotating sleeve 104d is reversed, the position limiting bump 105b-2 tends to slide from the lifting groove 105a-3 into the horizontal groove 105a-2, causing the slide block 105b-5 to slide downwards. When the slide block 105b-5 slides along the annular groove 105c-2 to the end of the descending groove 105c-3, the slide block 105b-5 slides downwards into the interior of the descending groove 105c-3. Also, due to the restriction of the horizontal groove 105a-2 on the position limiting bump 105b-2, the female screw sleeve 105d is driven to rotate in the opposite direction, thereby separating it from the male screw sleeve 105e and unlocking the arc-shaped frame 102a. At this point, the arc-shaped frame 102a can be pulled out to replace the biomass raw material.

[0045] Finally, when the arc-shaped frame 102a is removed, the female thread sleeve 105d loses pressure, and the elasticity of the return spring 105f causes the slide sleeve 105c-1 to slide downward, causing the slide block 105b-5 to slide into the annular groove 105c-2. By further rotating the rotating sleeve 104d one full turn, the elasticity of the return spring 105f pushes down the slide sleeve 105c-1, causing the slide block 105b-5 to slide into the rising groove 105c-4, thereby achieving the return and enabling the next operation.

[0046] Alternatively, the lower end of the upward groove 105c-4 is positioned directly above the upper end of the downward groove 105c-3. In this case, the elasticity of the return spring 105f directly guides the slide block 105b-5 from inside the downward groove 105c-3 to the end of the upward groove 105c-4, thereby achieving automatic return.

[0047] As described above, the material stacking assembly 102 can automatically lock and secure itself during operation, and can self-unlock when the material is replaced, thereby facilitating the replacement of biomass pyrolysis raw materials.

In this embodiment, the hinged end plate 303 can be inverted and opened so that the user can take and place the material deposition assembly 102. The end plate 303 is made of an insulating material and achieves pyrolysis by heating the uniform heating cylinder assembly 101 located inside with the heating assembly 302 to raise its temperature. In this embodiment, if one pyrolysis mechanism is provided, the heating rise and containment mechanism 300 can enclose it, thereby improving the heating efficiency of the pyrolysis mechanism. The biomass pyrolysis apparatus further comprises a gas diversion mechanism 200. As shown in Figures 14, 15, 16, 19, 20, 21, and 22, the gas diversion mechanism 200 includes a sealed disk assembly 201 provided on a support base 301, and a support shaft base 202 provided on the support base 301.

[0049] Specifically, as shown in Figures 15 and 17, the heating assembly 302 includes an insulated case 302a provided on a support base 301, and a heating layer 302b provided on the insulated case 302a, and further includes a thermally conductive internal cavity 302c provided on the heating layer 302b. In this embodiment, the heating layer 302b has a heating function and can heat the thermally conductive internal cavity 302c, the inner wall of the thermally conductive internal cavity 302c is in close contact with the outer wall of the thermally conductive outer cylinder 101a, and uniform heat conduction is possible, the external heat-insulating case 302a provides heat insulation and heat retention, and heat dissipation is reduced, and in this embodiment, during the rotation of the pyrolysis mechanism, the thermally conductive outer cylinder 101a, whose exterior is in contact with the thermally conductive internal cavity 302c, rolls, continuously changing the position between the thermally conductive outer cylinder 101a and the internal storage cylinder 101c, and uniform heat conduction is possible by the thermally conductive metal ball 101b, thereby improving the pyrolysis efficiency. During use, the gas generated when the pyrolysis mechanism performs pyrolysis is discharged through an exhaust pipe, the gas is sent into the guide tank assembly 203 through the exhaust pipe, and finally discharged through the guide pipe assembly 204. A collection bag may be attached to the end of the guide pipe assembly 204 to collect the gas. During pyrolysis, the motor 401 is driven to rotate the pyrolysis mechanism, and the position between the thermally conductive outer cylinder 101a and the internal storage cylinder 101c is continuously changed, and heat can be uniformly conducted by the thermally conductive metal ball 101b, thereby improving the pyrolysis efficiency.

[0050] As a result, the apparatus can efficiently and uniformly raise the temperature during thermal decomposition, thereby improving the thermal decomposition efficiency.

Furthermore, the thermal conductive outer cylinders 101a of each pyrolysis mechanism are evenly spaced and circumferentially distributed on the outer wall of the flow guide tank assembly 203, and each thermal conductive outer cylinder 101a is in close contact with the inner wall of the thermal conductive inner cavity 302c. In this embodiment, the sealed disk assembly 201 seals the rotating flow guide tank assembly 203, and when the flow guide tank assembly 203 rotates, the pyrolysis mechanism rotates with it, and during rotation, under the action of the thermal conductive metal balls 101b, the thermal conductive outer cylinders 101a roll, changing the heat conduction position of the thermal conductive outer cylinders 101a, thereby achieving uniform heating of the internal storage cylinder 101c.

[0052] As explained in Figures 15, 16, 18, and 21, the rotary drive mechanism 400 further includes a transmission gear 404 provided on the rotary sleeve 104d, and the output gear 402 can drive the rotation of the transmission gear 404 by driving the rotation of the gear disc 403. In this embodiment, one end of the transmission gear 404 is fixedly connected to one end of the rotary sleeve 104d, and the gear disc 403 drives the transmission gear 404 to rotate, thereby ensuring uniform heat conduction and thoroughly mixing the biomass raw material. Specifically, as shown in Figure 20, the sealed disk assembly 201 includes a chassis 201a mounted on a support base 301, and gaskets number 1 201b, number 2 201c, number 3 201d, and number 4 201e fitted sequentially on the chassis 201a. In this embodiment, gaskets number 1 201b, number 2 201c, number 3 201d, and number 4 201e are coaxial and their diameters decrease sequentially.

[0053] Furthermore, as shown in Figures 19, 20, and 21, the flow guide tank assembly 203 includes a numbered tank 203a rotatably mounted on a support shaft base 202, and numbered tanks 203b, 3, and 4 are sequentially fitted inside the numbered tank 203a. In this embodiment, the numbered tanks 203a, 203b, 3, and 4 are coaxial and their diameters decrease sequentially. The numbered tanks 203a, 203b, 3, and 4 are sealed by numbered gaskets 201b, 201c, 3, and 4, respectively.

[0054] Preferably, as shown in Figure 19, the guide pipe assembly 204 includes a guide pipe 1 204a, one end of which is provided between tank 1 203a and tank 2 203b, and a guide pipe 2 204b, one end of which is provided between tank 2 203b and tank 3 203c, and further includes a guide pipe 3 204c, one end of which is provided between tank 3 203c and tank 4 203d, and a guide pipe 4 204d, one end of which is provided inside tank 4 203d, and in this embodiment, guide pipe 1 204a The first channel 204b can extract gas between tank 1 203a and tank 2 203b, the second channel 204b can extract gas between tank 2 203b and tank 3 203c, the third channel 204c can extract gas between tank 3 203c and tank 4 203d, and the fourth channel 204d can extract gas from tank 4 203d. This allows for the extraction of gas from multiple experimental data sets, facilitating the comparison of experimental data.

[0055] Here, as shown in Figure 21, the conduit assembly 206 includes conduits 1, 2, 3, and 4 respectively, which are installed sequentially through tanks 1, 203a, 2, 3, 203b, 3, 203c, and 4, respectively. In this embodiment, conduit 1 206a is installed between tanks 1 and 2, 2, 3, and 4 so as to pass through; conduit 206b 2 is installed between tanks 2 and 3, 3, and 4 so as to pass through; conduit 3 206c 2 is installed between tanks 3 and 4, and 4, 4, is installed inside tank 4, 203d so as to pass through; thereby independently collecting and transporting gases generated by different pyrolysis mechanisms.

[0056] During use, biomass raw materials are added to the inside of multiple pyrolysis mechanisms, heating is performed by the heating layer 302b, and the heat-conductive internal cavity 302c conducts heat. When the motor 401 rotates, the heat-conductive outer cylinder 101a rolls along the inside of the heat-conductive internal cavity 302c, while the rotating sleeve 104d rotates.

[0057] When actually used, the gas generated by each pyrolysis mechanism is sent through the exhaust pipe into the interiors of the first, second, third, and fourth conduits 206a, 206b, 206c, and 206d, respectively. It then passes through the independent spaces formed by the first, second, third, and fourth tanks 203a, 203b, 203c, and 203d, and finally exits through the first, second, and fourth guide pipes 204a, 204b, 204c, and 204d, respectively. This enables the collection and processing of multiple experimental data, facilitating easy experimental comparisons.

[0058] As described above, the present invention allows for the simultaneous execution of pyrolysis experiments by arranging multiple pyrolysis mechanisms, thereby improving experimental efficiency, facilitating data comparison, maintaining good thermal conductivity and improving pyrolysis performance when multiple pyrolysis mechanisms conduct pyrolysis experiments simultaneously, and increasing the accuracy of experimental results, effectively shortening the experimental period, and improving experimental efficiency by having each pyrolysis mechanism transport the product through an independent passage.
