Description

Technical Field

[0001] This invention belongs to the field of pyrolysis technology and relates to a pyrolysis device and method for the synergistic treatment of multi-source organic solid waste with longitudinal flexible filaments. Background Technology

[0002] Large quantities of multi-source organic waste (such as wood fiber biomass, waste textiles, rubber products, and plastic products) are generated annually through production and daily life activities. Traditional methods of disposal, such as indiscriminate dumping or landfilling, not only cause severe soil, water, and air pollution but also result in a significant waste of the hydrocarbon resources contained within. Pyrolysis technology, as a highly efficient thermochemical conversion method, offers significant advantages over traditional methods like incineration and landfilling. These advantages include shorter processing cycles, higher conversion efficiency, significant volume reduction, efficient solidification of heavy metals, and the ability to inhibit the formation of harmful substances such as dioxins at the source. Furthermore, it yields high-value-added solid, liquid, and gaseous three-phase products (such as biochar, pyrolysis oil, and combustible gas), thus making it a crucial development direction for the resource utilization of multi-source organic waste.

[0003] However, existing pyrolysis units still face a series of technical bottlenecks when processing the aforementioned multi-source organic solid wastes. Due to the complex composition of the raw materials, some components (such as plastics, rubber, and certain hemicellulose) are prone to surface softening and melting under heating conditions. Simultaneously, the raw materials often contain large-sized flakes, lumps, or fibrous materials, which easily cause physical blockages at the feed inlet, reaction section, and slag outlet within conventional pyrolysis reactors. More seriously, softened materials rapidly form a coking and slag layer upon contact with high-temperature walls or moving parts. This layer significantly hinders heat transfer to the material's interior, reducing the pyrolysis reaction rate and conversion uniformity. Furthermore, it continuously accumulates and reduces the effective flow cross-section, ultimately forcing the unit to shut down for slag removal, making long-term continuous and stable operation impossible.

[0004] To alleviate the aforementioned problems, existing technologies attempt to perform additional crushing, pulverizing, or homogenization pretreatment on the raw materials. However, this not only significantly increases the overall power consumption of the reaction system, greatly increasing equipment investment and operating costs, but also results in a bulky pretreatment unit, reducing the system's economic efficiency and engineering practicality. In recent years, some solutions have proposed using flexible wires combined with flexible scrapers to dynamically clean the inner wall and moving parts of the pyrolysis reactor, which can solve the problem of large pieces of coke and waste residue to some extent. However, practice has shown that for highly adhesive multi-source organic waste (such as mixtures containing a high proportion of plastics or rubber), the pyrolysis residue has a high content of viscous mesophase components. During continuous operation, these components gradually deposit and dehydrate and carbonize on the surface of the flexible wires and in the gaps between the scrapers, forming an extremely stubborn, dense, and sticky residue. This type of residue has a strong bond with the matrix, and cannot be effectively peeled off and removed by intermittent collisions of the flexible scraper alone. As the operating time increases, this residue will continue to thicken, causing the flexible wires to lose their flexibility and scraping ability, resulting in a continuous decline in pyrolysis efficiency and inducing secondary blockage problems, which seriously restricts the long-term stable and reliable operation of the device. Summary of the Invention

[0005] To address the technical problems of existing pyrolysis devices in treating organic waste, such as easy softening and adhesion of raw materials leading to blockage, severe coking and slagging, high pretreatment costs, excessive equipment size, and low space utilization, this invention provides a pyrolysis device and method for the co-processing of multi-source organic solid waste with longitudinal flexible filaments.

[0006] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, the present invention provides a pyrolysis device for the synergistic treatment of multi-source organic solid waste with longitudinal flexible filaments, comprising: The pyrolysis furnace is a hollow cylindrical structure, and its interior is divided into an oxygen-free zone and an oxygen-containing zone along the circumference. A rotating shaft is located inside the pyrolysis furnace, and both ends of the rotating shaft are rotatably connected to the two inner sidewalls of the pyrolysis furnace, respectively. A flexible reaction cage includes multiple flexible filaments and finned plate units disposed at both ends of a rotating shaft. Each finned plate unit includes multiple fins spaced circumferentially along the rotating shaft. A first end of each fin is connected to the rotating shaft, and a second end extends radially outward along the rotating shaft, with a groove provided on the second end. The fins in two finned plate units correspond one-to-one along the axial direction of the rotating shaft, and the grooves on the corresponding two fins are positioned opposite each other. Both ends of each flexible filament are connected to two opposite grooves, and the multiple flexible filaments are spaced circumferentially along the rotating shaft. A hot roller mechanism is located within the aerobic zone of the pyrolysis furnace; the hot roller mechanism includes a hot roller and a support; the support is fixed to the inner surface of the pyrolysis furnace; both ends of the hot roller are fixed to the support; the hot roller is located outside the flexible reaction cage; the surface of the hot roller is provided with annular grooves and air holes. The baffles are disposed on both circumferential and radial sides of the aerobic zone, and together with the surface of the flexible reaction cage and the fins, they enclose the aerobic zone to form a sealed inner cavity.

[0007] Preferably, the baffle includes a flexible baffle, a fixed baffle, and side plates; the fixed end of the flexible baffle is fixed to the inner surface of the pyrolysis furnace, and the free end extends to the outer surface of the flexible reaction cage and contacts the flexible wire; the fixed baffle is disposed between adjacent fins, and the four sides of the fixed baffle are respectively fixedly connected to adjacent fins and a pair of side plates; the side plates are vertically fixed to the rotating shaft, and the edges of the side plates are connected to the ends of the fins; the flexible baffle, the fixed baffle, the side plates, and the fins together enclose the aerobic zone to form an inner cavity.

[0008] Preferably, the outer surface of the pyrolysis furnace is provided with a feed inlet, a discharge outlet, a gas outlet, and a gas extraction outlet; the feed inlet, the discharge outlet, and the gas outlet are located on the outer surface of the pyrolysis furnace corresponding to the oxygen-free zone; the gas extraction outlet is located on the outer surface of the pyrolysis furnace corresponding to the oxygen-containing zone.

[0009] Preferably, the feed inlet is connected to the feeding device; the discharge outlet is connected to the solid collection system; the gas outlet is connected to the separation and condensation system; and the exhaust port is connected to the flue gas treatment system.

[0010] Preferably, the surface of the hot roller is uniformly arranged with a plurality of annular grooves along the axial direction, and the spacing between adjacent annular grooves is the same as the spacing between adjacent flexible filaments; the cross-sectional width and depth of the annular grooves are not less than the diameter of the flexible filaments; the air holes are disposed at the bottom of the annular grooves; and the roller length of the hot roller is less than the length of the fin plate.

[0011] Preferably, there is a first gap between the end of the fin and the inner wall of the pyrolysis furnace; the first gap is larger than the diameter of the hot roller; the length of the flexible baffle is greater than the length of the first gap; and the second gap between the flexible baffle and the side plate is less than 2 mm.

[0012] Preferably, the hot roller mechanism includes multiple hot rollers, which extend circumferentially from one end to the other along the aerobic zone, with the cross-sectional dimensions of the annular grooves on each hot roller decreasing sequentially.

[0013] Preferably, both ends of the rotating shaft are rotatably connected to the two inner sidewalls of the pyrolysis furnace via bearings; a sealing ring is provided at the junction of the inner sidewall of the pyrolysis furnace and the rotating shaft; both ends of the rotating shaft extend out of the pyrolysis furnace and are respectively connected to an external drive.

[0014] Preferably, the oxygen-free zone has a first boundary and a second boundary in the circumferential direction of the pyrolysis furnace; the first boundary is located at the highest point of the circumference of the internal cross-section of the pyrolysis furnace; the second boundary is located behind the first boundary in the rotation direction along the rotation axis; with the axis of the pyrolysis furnace as the center, the central angle of the fan-shaped area occupied by the oxygen-containing zone is 60° to 180°.

[0015] Secondly, this invention provides a pyrolysis method for the synergistic treatment of multi-source organic solid waste with longitudinal flexible filaments, comprising the following steps: S1. Drive the rotating shaft to rotate, thereby causing the flexible reaction cage to rotate around the axis of the rotating shaft; S2. The organic solid waste is fed into the oxygen-free zone of the pyrolysis furnace, so that the organic solid waste adheres to the flexible filament, and is heated under oxygen-free conditions to cause the organic solid waste to undergo a pyrolysis reaction and generate pyrolysis residue. S3. By rotating the flexible reaction cage, the flexible ribbon with pyrolysis residues is introduced into the oxygen zone of the pyrolysis furnace. S4. In the oxygenated zone, in the sealed inner cavity formed by the baffles, oxygen is released to the flexible yarn through the air holes on the surface of the hot roller, and the hot roller is used to heat the flexible yarn so that the pyrolysis residue is burned off. S5. After cleaning, the flexible filaments continue to rotate with the flexible reaction cage and return to the oxygen-free zone. Repeat steps S2 to S5 to achieve continuous processing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By dividing the interior of the pyrolysis furnace into an anaerobic and an aerobic zone along its circumference, and driving the flexible reaction cage to rotate continuously via a rotating shaft, the multi-source organic solid waste softens upon heating in the anaerobic zone and naturally adheres to the longitudinal flexible filaments. This avoids coking and blockage caused by large-area contact between the raw materials and the furnace wall, and also reduces adhesion by utilizing the gaps between the flexible filaments. When the flexible filaments carrying pyrolysis residues are transferred into the aerobic zone, the annular grooves and pores on the surface of the hot rollers work together to precisely release oxygen through the pores at the moment the flexible filaments are embedded in the annular grooves, supplemented by high-temperature heating, so that the stubborn, dense, and sticky residues are fully oxidized, burned, and removed. At the same time, the baffles, the flexible reaction cage, and the fins together form a sealed inner cavity, effectively isolating the atmospheres of the aerobic and anaerobic zones, preventing oxygen leakage and pyrolysis gas cross-contamination. Thus, without the need for complex pretreatment of the raw materials, online self-cleaning, continuous and stable operation, high space utilization, and synergistic and efficient treatment of multi-source organic solid waste are achieved.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings: The first objective of this invention is to provide a pyrolysis device for the co-treatment of multi-source organic solid waste with longitudinal flexible filaments, such as... Figure 1 and Figures 3-5 As shown, it includes: The pyrolysis furnace 1 is a hollow cylindrical structure, and its interior is divided into an oxygen-free zone A and an oxygen-rich zone B along the circumferential direction. A rotating shaft 2 is located inside the pyrolysis furnace 1, and both ends of the rotating shaft 2 are rotatably connected to the two inner sidewalls of the pyrolysis furnace 1, respectively. A flexible reaction cage 3 includes multiple flexible filaments 32 and finned plate units disposed at both ends of a rotating shaft 2. Each finned plate unit includes multiple finned plates 31 spaced apart circumferentially along the rotating shaft 2. The first end of each finned plate 31 is connected to the rotating shaft 2, and the second end extends radially outward along the rotating shaft 2, with a groove provided on the second end. The finned plates 31 in two finned plate units correspond one-to-one along the axial direction of the rotating shaft 2, and the grooves on the corresponding two finned plates 31 are positioned opposite each other. The two ends of each flexible filament 32 are respectively connected to two opposite grooves, and the multiple flexible filaments 32 are spaced apart circumferentially along the rotating shaft 2. A hot roller mechanism 4 is located in the aerobic zone B within the pyrolysis furnace 1. The hot roller mechanism 4 includes a hot roller 41 and a support 42. The support 42 is fixed to the inner surface of the pyrolysis furnace 1. Both ends of the hot roller 41 are fixed to the support 42. The hot roller 41 is located outside the flexible reaction cage 3. The surface of the hot roller 41 is provided with an annular groove 43 and air holes 44. Baffle 5 is disposed on both circumferential and radial sides of the aerobic zone B, and together with the surface of the flexible reaction cage 3 and the fin plate 31, surrounds the aerobic zone B to form a sealed inner cavity.

[0027] Specifically, the present invention includes a horizontally placed hollow cylindrical pyrolysis furnace 1, the interior of which is divided circumferentially into an oxygen-free zone A and an oxygen-rich zone B. A rotating shaft 2 is provided inside the pyrolysis furnace 1, defining the beginning and end points of the oxygen-free zone A and the oxygen-rich zone B according to the rotation direction of the rotating shaft 2. Both ends of the rotating shaft 2 are rotatably connected to the two inner sidewalls of the pyrolysis furnace 1. A flexible reaction cage 3 is provided on the rotating shaft 2, the flexible reaction cage 3 including two finned plate units fixed to both ends of the rotating shaft 2. Each finned plate unit consists of multiple finned plates 31 evenly spaced along the circumference of the rotating shaft 2, each finned plate 31 being of equal length. The first end of each finned plate 31 is fixed to the rotating shaft 2, and the second end extends radially outward and has a groove. The groove positions on the axially opposite finned plates 31 of the two finned plate units correspond one-to-one. The two ends of multiple flexible wires 32 are respectively tensioned and connected in the opposite grooves, and are arranged sequentially at intervals along the circumference of the rotating shaft 2, thereby forming a ring-shaped mesh surrounding the rotating shaft 2. A hot roller mechanism 4 is provided in the aerobic zone B of the pyrolysis furnace 1. It includes a support 42 fixed to the inner surface of the pyrolysis furnace 1 and a hot roller 41 installed on the support 42. The hot roller 41 is located outside the flexible reaction cage 3 and parallel to the rotation axis 2. The surface of the hot roller 41 is provided with an annular groove 43 that matches the movement trajectory of the flexible wire 32 and a vent 44 that connects to an external oxygen supply source. The hot roller 41 is provided with a heating element inside so that its surface can maintain a high temperature (usually 600~900°C) sufficient to ignite the residue during operation. In addition, baffles 5 are provided on both circumferential sides (i.e., the front and rear boundaries along the circumferential direction of the pyrolysis furnace 1) and radial sides (i.e., the two ends along the axial direction of the rotation axis 2) of the aerobic zone B. These baffles 5, together with the annular mesh surface of the flexible reaction cage 3 and the fin plate 31, enclose the aerobic zone B to form a relatively sealed inner cavity. The inner cavity maintains the required oxygen concentration through the vent 44 and forms a slight negative pressure with the help of the exhaust port 14 to prevent oxygen from leaking into the oxygen-free zone A.

[0028] During operation, the rotating shaft 2 drives the flexible reaction cage 3 to rotate continuously. The raw material falls from the oxygen-free zone A onto the flexible filament 32. After being heated and softened, it naturally adheres to the surface of the flexible filament 32 and undergoes pyrolysis. As the flexible filament 32 carries the pyrolysis residue into the sealed inner cavity of the oxygen-rich zone B, the residue undergoes precise and controlled oxidation and combustion as it passes through the high-temperature annular groove 43 of the hot roller 41. At the same time, the baffle 5 effectively prevents oxygen from leaking into the oxygen-free zone A, thereby achieving online self-cleaning and continuous pyrolysis.

[0029] The device significantly increases the contact and adhesion area between multi-source organic solid waste and hot surfaces through the dynamic reaction interface formed by the longitudinal flexible filaments 32, while avoiding large-area coking and clogging of materials on the furnace wall or large fixed components. The local high-temperature oxidation zone formed by the hot rollers 41 and baffles 5 in the aerobic zone B can effectively remove stubborn, dense, and sticky residues on the flexible filaments 32, achieving online self-cleaning of the device. The dynamic sealing structure formed by the baffles 5 and the flexible reaction cage 3 ensures the independence of the atmosphere in the anaerobic zone A and the aerobic zone B, allowing the pyrolysis reaction and oxidation regeneration processes to be continuously and paralleled in the same furnace body in a circumferential partition without the need for shutdown for cleaning. This greatly improves the co-processing efficiency, operational stability, and space utilization of multi-source organic solid waste such as waste plastics, waste textiles, and waste tires.

[0030] For example, such as Figure 2 As shown, the baffle 5 includes a flexible baffle 51, a fixed baffle 52, and a side plate 53; the fixed end of the flexible baffle 51 is fixed to the inner surface of the pyrolysis furnace 1, and the free end extends to the outer surface of the flexible reaction cage 3 and contacts the flexible wire 32; the fixed baffle 52 is disposed between adjacent fins 31, and the four sides of the fixed baffle 52 are respectively fixedly connected to adjacent fins 31 and a pair of side plates 53; the side plates 53 are vertically fixed to the rotating shaft 2, and the edge of the side plate 53 is connected to the end of the fin 31; the flexible baffle 51, the fixed baffle 52, the side plate 53, and the fin 31 together enclose the aerobic zone B to form an inner cavity.

[0031] Specifically, the baffle 5 includes a flexible baffle 51, a fixed baffle 52, and side plates 53; wherein, the flexible baffle 51 is a flexible structure located on the outside of the flexible reaction cage 3; the fixed baffle 52 and side plates 53 are rigid structures, both located on the inside of the flexible reaction cage 3. The flexible baffle 51 is a square structure, its fixed end is fixed to the inner surface of the pyrolysis furnace 1 by bolts or welding, and its free end extends radially inward to the outer surface of the flexible reaction cage 3, and maintains a certain pressure sliding contact with the flexible wire 32 by its own elastic bending; the fixed baffle 52 is a rigid thin plate, disposed between every two adjacent fins 31, and its four sides are fixedly connected to the adjacent fins 31 and a pair of side plates 53, thereby forming a closed space between the fins 31, side plates 53 and fixed baffle 52, which rotates with the rotating shaft 2 to accommodate and guide the root region of the flexible wire 32; the pair of side plates 53 3 is vertically fixed on the rotating shaft 2 and located at both ends of the flexible reaction cage 3. Its edges are fixedly connected to the ends of each fin 31, thereby connecting all the fins 31 into an integral frame. At the same time, the outer edge of the side plate 53 and the two sides of the flexible baffle 51 maintain a very small gap to limit gas leakage. In this way, the flexible baffle 51, the fixed baffle 52, the side plate 53 and the fin 31 together enclose the oxygenated area B, forming a relatively sealed inner cavity. The inner cavity only has a dynamic line contact gap at the free end where the flexible wire 32 passes through the flexible baffle 51. The rest of the part is rigidly connected or has a very small gap fit.

[0032] During operation, the rotating shaft 2 drives the flexible reaction cage 3, which consists of fins 31, fixed baffles 52, side plates 53, and flexible wires 32, to rotate continuously. When the flexible wires 32 carry pyrolysis residues from the oxygen-free zone A into the oxygen-rich zone B, they must slide under the flexible baffles 51. At this time, the flexible baffles 51 use the pressure generated by their elastic deformation to squeeze and scrape the surface of the flexible wires 32. On the one hand, this helps to peel off large pieces of coke, and on the other hand, the close fit between the flexible baffles 51 and the flexible wires 32 forms a dynamic gas-tight barrier, effectively preventing oxygen in the oxygen-rich zone B from leaking to the oxygen-free zone A along the surface of the flexible wires 32. At the same time, the fixed baffles 52 and side plates 53 further block the possible diffusion paths of the gas from the inside and the end face.

[0033] Furthermore, the circumferential width of all flexible baffles 51 (i.e., the arc length covered from the first flexible baffle 51 to the last flexible baffle 51) is not less than the distance between two adjacent fins 31 (i.e., the circumferential distance between two fins 31). When the flexible reaction cage 3 rotates, regardless of the position of the flexible wires 32 and fins 31, at least one flexible baffle 51 will always remain in contact with the passing fin 31 or flexible wire 32 at both the beginning and end of the aerobic zone B. This prevents all flexible baffles 51 from being simultaneously located in the gap between two adjacent fins 31, thus avoiding a sealing failure. This effectively prevents oxygen in the aerobic zone B from leaking into the anaerobic zone A along the gaps between the fins 31, and also prevents pyrolysis gas from the anaerobic zone A from entering the aerobic zone B and causing unintended combustion, ensuring the independence and stability of the atmosphere in the two reaction zones.

[0034] For example, the outer surface of the pyrolysis furnace 1 is provided with a feed inlet 11, a discharge outlet 12, a gas outlet 13 and a gas extraction outlet 14; the feed inlet 11, the discharge outlet 12 and the gas outlet 13 are provided on the outer surface of the pyrolysis furnace 1 corresponding to the oxygen-free zone A; the gas extraction outlet 14 is provided on the outer surface of the pyrolysis furnace 1 corresponding to the oxygen-rich zone B.

[0035] Specifically, the feed inlet 11 is located above the beginning of the anaerobic zone A and is used to feed multi-source organic solid waste raw materials into the pyrolysis furnace 1. It can be connected to a feeding device with a gate to achieve continuous or intermittent feeding. The discharge outlet 12 is usually located at the bottom of the pyrolysis furnace 1 and is used to discharge solid residues (such as coke and ash) generated after pyrolysis through stripping and combustion removal. It can be connected to a solid collection system. The gas outlet 13 is used to export combustible gases or pyrolysis vapors generated in the anaerobic zone A. It is generally connected to a separation and condensation system to recover liquid products and non-condensable gases. The exhaust port 14 is located on the outer surface of the aerobic zone B and is used to extract the flue gas generated in the aerobic zone B through combustion. It is usually connected to a flue gas treatment system and creates a negative pressure environment in this area. In addition, a heat exchange flue is arranged on the outside of the pyrolysis furnace 1. This heat exchange flue is used to introduce solid carbon and non-condensable gases generated during pyrolysis and burn them. The high-temperature flue gas generated by combustion is introduced into the heat exchange flue and heat is transferred to the pyrolysis furnace 1 through heat exchange, thereby realizing the self-heating of the pyrolysis furnace 1.

[0036] For example, the surface of the hot roller 41 is uniformly arranged with a plurality of annular grooves 43 along the axial direction, and the spacing between adjacent annular grooves 43 is the same as the spacing between adjacent flexible filaments 32; the cross-sectional width and depth of the annular grooves 43 are not less than the diameter of the flexible filaments 32; the air holes 44 are disposed at the bottom of the annular grooves 43; the roller length of the hot roller 41 is less than the length of the fin plate 31.

[0037] Specifically, the surface of the hot roller 41 is uniformly arranged with multiple annular grooves 43 along its axial direction. The spacing between adjacent annular grooves 43 is the same as the spacing between adjacent flexible filaments 32, so that when the flexible reaction cage 3 rotates to the aerobic zone B, each flexible filament 32 can be accurately aligned and embedded in the corresponding annular groove 43, achieving a one-to-one precise fit. The cross-sectional width and depth of the annular groove 43 are not less than the diameter of the flexible filament 32, which not only ensures that the flexible filament 32 can smoothly enter and exit the annular groove 43, but also provides sufficient space for the dense and sticky residues attached to the surface of the flexible filament 32, preventing the residues from being squeezed and accumulated due to the small gaps, thus blocking the annular groove 43 or jamming the flexible filament 32. The air vent 44 is located at the bottom of the annular groove 43 and opens towards the flexible filament 32. When the flexible filament 32 is embedded in the annular groove 43, the oxygen released from the air vent 44 can directly act on the residue on the surface of the flexible filament 32, achieving localized and precise oxygen supply and combustion. This avoids ineffective diffusion of oxygen to other areas of the aerobic zone B, improving combustion efficiency and oxygen utilization. In addition, the length of the hot roller 41 is less than the length of the fin plate 31, so that the hot roller 41 is completely located between the side plates 53 at both ends in the axial direction, avoiding interference with the side plates 53. At the same time, it ensures that the entire effective working section of the flexible filament 32 (i.e., the part located between the two fin plates 31) can contact the annular groove 43 to obtain sufficient cleaning treatment.

[0038] For example, there is a first gap between the end of the fin 31 and the inner wall of the pyrolysis furnace 1; the first gap is larger than the diameter of the hot roller 41, thereby providing sufficient space for the installation and arrangement of the hot roller 41, ensuring that the hot roller 41 can be smoothly placed on the outside of the flexible reaction cage 3 without interfering with the fin 31; the length of the flexible baffle 51 is greater than the length of the first gap, with a difference of 2~10mm, which makes the flexible baffle 51 inevitably bend and deform inward after installation, thereby generating continuous and controllable elastic pressure on the passing flexible wire 32, ensuring the mechanical force required for squeezing and scraping, and avoiding excessive pressure that would cause excessive wear or obstruction of movement of the flexible wire 32; the second gap between the flexible baffle 51 and the side plate 53 is less than 2mm, and this gap allows the flexible reaction cage 3 to rotate freely relative to the fixed flexible baffle 51, while effectively limiting the channel for gas leakage from the side of the baffle 5 in the aerobic zone B, enhancing the sealing effect of the sealed inner cavity.

[0039] For example, the hot roller mechanism 4 includes multiple hot rollers 41, which extend circumferentially from one end to the other in the aerobic zone B. The cross-sectional dimensions of the annular grooves 43 on each hot roller 41 decrease sequentially. When the flexible filament 32 enters the aerobic zone B from the oxygen-free zone A, the dense and sticky residue adhering to its surface is relatively large and stubborn. The larger annular groove 43 at the beginning can accommodate the residue and allow sufficient oxygen to enter, achieving initial efficient oxidation and combustion, thus rapidly reducing the volume of the residue. As the flexible filament 32 passes through subsequent hot rollers 41, the residue is gradually burned off, and its volume is significantly reduced. At this point, using annular grooves 43 with gradually decreasing dimensions ensures that the flexible filament 32 always maintains appropriate contact and friction with the groove wall. This avoids the residue not being effectively scraped off and fully oxidized due to an excessively large groove, and also prevents the flexible filament 32 from getting stuck or mechanically damaged due to an excessively small groove.

[0040] For example, the two ends of the rotating shaft 2 are rotatably connected to the two inner sidewalls of the pyrolysis furnace 1 via bearings; a sealing ring is provided at the junction of the inner sidewall of the pyrolysis furnace 1 and the rotating shaft 2; the two ends of the rotating shaft 2 extend out of the pyrolysis furnace 1 and are respectively connected to an external driver.

[0041] Specifically, the two ends of the rotating shaft 2 are rotatably connected to the two inner walls of the pyrolysis furnace 1 via bearings (e.g., self-aligning roller bearings or deep groove ball bearings). The inner ring of the bearing is interference-fitted with the rotating shaft 2, and the outer ring is fixedly installed with the bearing seat on the inner wall of the pyrolysis furnace 1 to ensure that the rotating shaft 2 can rotate smoothly and with low resistance under high temperature conditions. At the junction of the inner wall of the pyrolysis furnace 1 and the rotating shaft 2, i.e., the shaft penetration part on the outer side of the bearing, a high-temperature resistant sealing ring (e.g., graphite packing seal or metal bellows seal) is provided. This sealing ring is tightly attached to the surface of the rotating shaft 2, effectively preventing the gas inside the pyrolysis furnace 1 (including the pyrolysis gas in the oxygen-free zone A and the oxygen-containing flue gas in the oxygen-containing zone B) from leaking outward along the shaft gap, and also preventing external air from seeping into the furnace and interfering with the reaction atmosphere. The two ends of the rotating shaft 2 extend out of the pyrolysis furnace 1 and are connected to an external drive (e.g., a combination of a variable frequency speed control motor and a reducer) via a coupling. The drive provides adjustable rotational torque, driving the flexible reaction cage 3 to rotate continuously at a set speed.

[0042] For example, the oxygen-free zone A has a first boundary and a second boundary in the circumferential direction of the pyrolysis furnace 1: the first boundary is located at the highest point of the circumference of the internal cross-section of the pyrolysis furnace 1, which serves as the starting point of the oxygen-free zone A, facilitating the uniform distribution of raw materials onto the surface of the flexible reaction cage 3 under gravity when feeding from above; the second boundary is located behind the first boundary along the rotation direction of the rotation axis 2, that is, along the rotation direction of the rotation axis 2, extending backward from the highest point to the starting point of the oxygen-containing zone B, thereby defining the circumferential range occupied by the oxygen-free zone A; with the axis of the pyrolysis furnace 1 as the center, the central angle of the fan-shaped area occupied by the oxygen-containing zone B is 60° to 180°, which ensures that the residues on the flexible filament 32 have sufficient travel to be thoroughly removed by high-temperature oxidation and mechanical scraping, while preventing the oxygen-containing zone B from becoming too long due to excessive angle, thus increasing the sealing difficulty or excessive heat consumption, and at the same time reserving sufficient pyrolysis reaction space for the oxygen-free zone A, thereby achieving a balanced distribution of pyrolysis and self-cleaning in the circumferential direction, ensuring continuous and efficient operation of the device.

[0043] For example, the flexible filament 32 can be made of stainless steel, aluminum silicate fiber, or aramid fiber. Stainless steel wire has good high-temperature resistance, oxidation resistance, and mechanical strength, making it suitable for high-temperature conditions that require repeated compression and abrasion. Aluminum silicate fiber is soft and resistant to thermal shock, making it suitable for scenarios with higher flexibility requirements and frequent thermal shock. Aramid fiber combines high tensile strength and thermal stability, enabling self-cleaning of the surface while ensuring bonding and load-bearing capacity. The baffle 5 is made of stainless steel sheet, utilizing the good creep resistance and corrosion resistance of stainless steel at high temperatures. Its appropriate elastic deformation capacity allows the flexible baffle 51 and side plate 53 to maintain a tight fit with the fixed baffle 52 during long-term operation, forming a reliable seal.

[0044] The second objective of this invention is to provide a pyrolysis method for the co-treatment of multi-source organic solid waste with longitudinal flexible filaments, comprising the following steps: S1. Drive the rotating shaft 2 to rotate, thereby causing the flexible reaction cage 3 to rotate around the axis of the rotating shaft 2; S2. The organic solid waste is fed into the oxygen-free zone A of the pyrolysis furnace 1, so that the organic solid waste adheres to the flexible wire 32, and is heated under oxygen-free conditions to cause the organic solid waste to undergo a pyrolysis reaction and generate pyrolysis residue. S3. By rotating the flexible reaction cage 3, the flexible filament 32 with pyrolysis residues is brought into the oxygen zone B of the pyrolysis furnace 1. S4. In the aerobic zone B, in the closed cavity formed by the baffles 5, oxygen is released to the flexible filament 32 through the air holes 44 on the surface of the hot roller 41, and the flexible filament 32 is heated by the hot roller 41 to burn and remove the pyrolysis residue. S5. The cleaned flexible wire 32 continues to rotate with the flexible reaction cage 3 and returns to the oxygen-free zone A. Steps S2 to S5 are repeated to achieve continuous processing.

[0045] Specifically, it includes: The rotating shaft 2 driven by the driver rotates at a preset speed, causing the flexible reaction cage 3 to rotate uniformly around its axis, and heating the entire pyrolysis furnace 1 to the target pyrolysis temperature; then, the multi-source organic solid waste raw materials are directly fed into the oxygen-free zone A of the pyrolysis furnace 1 through the feed port 11, and naturally fall onto the flexible wires 32 of the flexible reaction cage 3. Under the oxygen-free heating conditions, the surface of the raw materials softens and spontaneously adheres to the flexible wires 32. As the flexible reaction cage 3 continues to rotate, the adhered raw materials gradually complete the pyrolysis reaction in the oxygen-free zone A, generating pyrolysis gas and solid pyrolysis residues; When the flexible filament 32 carrying pyrolysis residues enters the aerobic zone B along with the flexible reaction cage 3, it first squeezes and scrapes against the flexible baffle 51 arranged at the head end of the aerobic zone B, causing the large pieces of coke and waste residue that are in block or sheet form after pyrolysis to be peeled off from the flexible filament 32 and fall to the discharge port 12 under the action of gravity for automatic discharge, thus completing the initial cleaning. Subsequently, the flexible filament 32 continues to move to the area where the hot roller mechanism 4 is located. Since the surface of the hot roller 41 has annular grooves 43 that correspond one-to-one with the flexible filament 32 and air holes 44 are provided in the grooves, the flexible filament 32 accurately passes through the high-temperature annular grooves 43. At this time, a suitable amount of oxygen is released into the narrow groove space through the air holes 44, and the high temperature maintained by the hot roller 41 itself causes the remaining dense and sticky residues (such as heavy tar and carbon deposits) on the flexible filament 32 to be fully oxidized and burned, thereby achieving deep cleaning. The flue gas produced by combustion is extracted through the exhaust port 14 and forms a negative pressure in the oxygenated zone B, effectively preventing oxygen from entering the oxygen-free zone A. The pyrolysis gas produced in the oxygen-free zone A is discharged from the exhaust port 13 and then condensed and separated to obtain liquid fuel and non-condensable gas.

[0046] Example 1 This embodiment provides a pyrolysis device for the co-treatment of multi-source organic solid waste with transverse flexible filaments. It includes a pyrolysis furnace 1, which is a horizontally placed hollow cylindrical structure with an inner diameter of 1000mm and a length of 600mm.

A flexible reaction cage 3 is fixed to the rotating shaft 2 and rotates with it. Its overall outer diameter is 1600mm, and it specifically includes 20 fins 31 and several flexible filaments 32. The axial length of all fins 31 is 500mm. One end of each fin 31 is uniformly fixed to the rotating shaft 2 along the circumference, and the other end has multiple opposite grooves along the axial direction. The flexible wire 32 is made of stainless steel wire with a diameter of 1mm. Each flexible wire 32 passes through the corresponding groove on each fin 31 in sequence and is tensioned to form an annular mesh surface. The interior of the pyrolysis furnace 1 is divided into an oxygen-free zone A and an oxygen-rich zone B along the circumference. The central angle corresponding to the oxygen-free zone A is 270°, and the central angle corresponding to the oxygen-rich zone B is 90°. The baffle 5 includes a flexible baffle 51, a fixed baffle 52, and a pair of side plates 53, according to Figure 1 and Figure 2 The arrangement is as follows: a pair of side plates 53 are vertically fixed to the rotating shaft 2 and connected to the two ends of each fin 31.

Six flexible baffles 51 are arranged side by side at the beginning and end of the aerobic zone B, and their distribution width is greater than that of the adjacent fins 31. The spacing of the fins 31 ensures dynamic sealing; the hot roller mechanism 4 is arranged in the aerobic zone B, which includes multiple hot rollers 41 and a bracket 42 fixed to the inner surface of the pyrolysis furnace 1. The two ends of the hot rollers 41 are mounted on the bracket 42, and the roller diameter is 100mm and the length is 460mm. Each hot roller 41 has parallel annular grooves 43 processed on its surface. The spacing between adjacent annular grooves 43 is equal to the spacing between adjacent flexible wires 32, and the cross-sectional dimension of the annular groove 43 is not less than the diameter of the flexible wire 32. An air hole 44 for releasing oxygen is opened on the side of the annular groove 43 near the flexible wire 32.
