Description

TECHNICAL FIELD

[0001] The present application relates to the field of biomass, in particular to a biomass waste degradation equipment. BACKGROUND

[0002] Biomass waste degradation is the process of converting organic waste such as agricultural straw, kitchen waste, and forestry residues into energy, materials, and high-value chemicals through physical, chemical, or biological technology. This process has three core significances for promoting sustainable development:

[0003] 1. Environmental governance: Avoiding open burning (such as straw) reduces PM2.5 emissions by more than 30%, and blocks methane (28 times the greenhouse effect of CO2) generated by waste landfill, controlling pollution from the source;

[0004] 2. Resource recycling: 1 ton of kitchen waste can produce 120m 3 of biogas (150 degrees of household electricity) through anaerobic fermentation, and straw can be enzymatically degraded to produce biodegradable plastic (PLA) to replace petroleum-based products, achieving a "waste-resource" closed loop;

[0005] 3. Economic efficiency: Degradation products such as biochar adsorbent (value ￥8000 / ton) and vanillin (food grade ￥2000 / kg) increase the added value of waste, driving the upgrading of green industries.

[0006] The Chinese patent document with the authorization announcement number CN111822487B proposes an intelligent biomass waste degradation equipment; it includes a degradation tank, a base, and a control box. The center of the upper surface of the base is provided with a rotating seat, and a load plate is arranged directly above the base. The lower surface of the load plate is provided with a rotating piece that is rotationally connected with the rotating seat. The left and right ends of the rotating seat are both fixed with telescopic devices. The top ends of the telescopic devices are rotationally connected with strip-shaped supporting plates. The left and right ends of the two strip-shaped supporting plates are respectively in abutment with the left and right ends of the lower surface of the load plate.

[0007] The existing biomass waste degradation equipment often uses steam alone to degrade biomass or first crushes the biomass before steam degradation. The size of the biomass raw material varies, and it is easy to accumulate and clog. The contact range with the steam cannot be guaranteed, often leading to uneven steam effect. Crushing before steam treatment can affect the degradation efficiency. These factors can lead to incomplete, inefficient, and thorough implementation of biomass waste degradation, which is not conducive to improving the reuse of biomass waste. SUMMARY

[0008] To address the problems existing in the background technology, a biomass waste degradation device is proposed. It is equipped with a pressurized steam generator, a translational pushing component, and a processing component working together. Extrusion, tumbling, and steam work simultaneously to promote degradation through multiple methods, making the degradation of biomass waste comprehensive, efficient, and thorough. This helps to improve the reuse rate of biomass waste and reduce environmental pollution.

[0009] This invention proposes a biomass waste degradation device, including a heated degradation tank, a pressurized steam generator, a translational pushing assembly, and a processing assembly. The heated degradation tank is horizontally positioned with a feed component at the top and a discharge component at the bottom, and a degradation chamber inside. Two sets of pressurized steam generators are located at opposite ends of the degradation chamber. The two sets of translational pushing assemblies are driven by a first drive component, moving horizontally between the two sets of pressurized steam generators and dividing the degradation chamber into a central degradation cavity and two side steam cavities. The translational pushing assembly has a multi-layered perforated rotating structure, which allows for connection or isolation between the degradation cavity and the steam cavity through rotation. The degradation cavity is pressurized by moving and squeezing, and the pressure is controlled by a pressure relief valve. The processing assembly is located between the feed component, the discharge component, and the two sets of translational pushing assemblies. It is configured as a deformable rhomboid frame structure. The front and rear corners are rotated and deformed by a second drive component, and the left and right corners are rotated and deformed by the translational pushing assemblies to squeeze and overturn the biomass waste within the rhomboid frame structure.

[0010] Preferably, the second driving component includes a mounting ring located between the two sets of translational pushing components and disposed along the inner wall of the degradation chamber; a slidable slider is disposed on the mounting ring; a cylinder is disposed on the slider facing the center of the mounting ring; the processing component is located at the center of the mounting ring, deformed by the pushing and pulling of the cylinders on both sides, and rotated by the sliding of the slider.

[0011] Preferably, the processing component includes a connecting frame; four sets of connecting frames are respectively arranged at the four vertices of the rhombus, and a rotatable processing frame is arranged between adjacent connecting frames; the four sets of processing frames form a rhombus frame structure with open top and bottom; the piston rods of the two sets of cylinders are connected one-to-one between the front and rear sets of opposite connecting frames; the processing frame is provided with hollow and degradation reinforcement parts, and a rotatable cutting blade is provided on the outer periphery.

[0012] Preferably, the four sets of processing racks are provided with a chute on one side facing the inside of the diamond-shaped frame structure; the degradation reinforcement includes a reinforcement seat that slides along the chute; and the reinforcement seat is provided with a raised reinforcement strip.

[0013] Preferably, a booster steam generator is provided at the center of one side of the steam chamber; the driving component is a cylinder, and multiple sets are provided along the outer periphery of the booster steam generator to act on the translational pushing component.

[0014] Preferably, the translational pushing assembly includes a piston frame that moves along the inner wall of the degradation chamber via a piston rod connected to cylinder two; a rotary drive seat one is provided in the middle of the piston frame, and a piston ring is connected to its outer periphery via a sealing plate; a piston disc is provided on the side facing the rhomboid frame structure, which rotates along the inner wall of the piston ring via the rotary drive seat one; a rotary drive seat two is provided at the center of the piston disc, and a vent is provided on its outer periphery; two sets of opposing connecting frames are connected one-to-one to the rotation shafts of the corresponding side drive seat two; the vent and the sealing plate are provided one-to-one, and when they are opposite each other, the vent is completely covered by the sealing plate, and when they are staggered, the vent is open.

[0015] Preferably, a ring-shaped pressure relief pipe is provided inside the piston ring; the pressure relief pipe is connected to a pressure relief head with a valve, and is also connected to a pressure relief valve through a gas pipe; the pressure relief head is embedded in the sealing plate and is connected to the degradation chamber.

[0016] Preferably, the feeding component includes a feeding box; the bottom of the feeding box is provided with a feeding port that communicates with the degradation chamber, and multiple sets of cutting rollers are provided inside.

[0017] Preferably, the discharge component includes a discharge box; the top of the discharge box is provided with a discharge port that communicates with the degradation process, the side wall is provided with a gas-liquid pipe, and the bottom is provided with a detachable discharge seat.

[0018] Compared with existing technologies, this invention has the following beneficial technical effects: The processing component with a rhomboid frame structure allows for the pushing and pulling of pairs of opposing connecting frames from the front and back, left and right, causing continuous deformation of the rhomboid frame structure. This repeatedly compresses the internal biomass, with the reinforcing seat enhancing the compression effect. The cutting blades cut the biomass waste outside the rhomboid frame structure, comprehensively assisting in degradation. During the compression process, the rotation of the rhomboid frame structure achieves a combination of flipping and crushing, comprehensively destroying the physical barriers and chemical structure of the biomass, thus significantly improving degradation efficiency. A translational pushing component with a multi-layered perforated rotating structure is also included. When the piston disc rotates to the point where the vent is opposite the sealing plate, and the vent is completely covered by the sealing plate, the piston disc is sealed, thus sealing the steam chamber and the degradation chamber. At this point, the movement of the piston disc allows for pushing and pulling of the two opposing connecting frames from the left and right sides, causing deformation of the rhomboid frame structure. Simultaneously, it pushes the biomass falling to the bottom of the degradation chamber into the rhomboid frame structure. When the piston disc rotates to the point where the vent and sealing plate intersect, the vent is opened. High-temperature, high-pressure steam can then enter the degradation chamber for high-temperature degradation. The final two sets of piston discs move relative to each other, increasing the pressure through compressed air. This further compresses the biomass within the rhomboid frame structure. The pressure relief head releases pressure instantaneously, using the pressure difference to trigger an "explosion" effect that destroys the fiber structure, completing further degradation. This invention employs a pressurized steam generator, a translational pushing component, and a processing component in tandem. Compression, tumbling, and steam work simultaneously, promoting degradation through multiple methods. This ensures comprehensive, efficient, and thorough degradation of biomass waste, improving its reuse rate while reducing environmental pollution. Attached Figure Description

Detailed Implementation

[0032] Example 1: This invention proposes a biomass waste degradation device, such as... Figures 1-4 As shown, the system includes a heated degradation tank 1, a pressurized steam generator 2, a translational pushing assembly 6, and a processing assembly 7. The heated degradation tank 1 is horizontally positioned with a feed component 4 at the top and a discharge component 3 at the bottom, and a degradation chamber inside. Two sets of pressurized steam generators 2 are located at opposite ends of the degradation chamber. The two sets of translational pushing assemblies 6 are driven by a first drive component 9, moving horizontally between the two sets of pressurized steam generators 2 and dividing the degradation chamber into a central degradation chamber and steam chambers on both sides. The translational pushing assembly 6 has a multi-layered perforated rotating structure, which allows for the connection or isolation of the degradation chamber and steam chamber through rotation. It pressurizes the degradation chamber through movement and compression, and the pressure is controlled by a pressure relief valve 5. The processing assembly 7 is located between the feed component 4, the discharge component 3, and the two sets of translational pushing assemblies 6. It is configured as a deformable rhomboid frame structure. The front and rear corners are rotated and deformed by a second drive component 8, and the left and right corners are rotated and deformed by the translational pushing assemblies 6, so as to compress and overturn the biomass waste within the rhomboid frame structure.

[0033] like Figure 5 As shown, the driving component 2 8 includes a mounting ring 801 located between the two sets of translational pushing components 6 and disposed along the inner wall of the degradation chamber; a slidable slider 803 is disposed on the mounting ring 801; a cylinder 802 is disposed on the slider 803 facing the center of the mounting ring 801. The processing component 7 is located at the center of the mounting ring 801, deformed by the pushing and pulling of the cylinders 802 on both sides, and rotated by the sliding of the slider 803.

[0034] like Figures 5-7 As shown, the processing component 7 includes a connecting frame 701; four sets of connecting frames 701 are respectively arranged at the four vertices of the rhombus, and a rotatable processing frame 702 is arranged between adjacent connecting frames 701; the four sets of processing frames 702 form a rhombus frame structure with open top and bottom; the piston rods of the two sets of cylinders 802 are connected one-to-one between the front and rear sets of opposite connecting frames 701; the processing frame 702 is provided with a hollow 704 and a degradation reinforcement, and a rotatable cutting blade 703 is provided on the outer periphery.

[0035] The synchronous extension and retraction of the piston rod of cylinder 802 allows for the pushing and pulling of two opposing connecting frames 701 from the front and rear sides, causing the rhomboid frame structure to deform. The sliding of slider 803 enables the rhomboid frame structure to rotate, repeatedly squeezing and turning the biomass waste, thus promoting its degradation. The perforated design 704 ensures air circulation within the degradation chamber, allowing for sufficient contact between the high-pressure steam and the biomass waste, while the degradation reinforcement enhances the degradation process.

[0036] It should be further explained that the four sets of processing racks 702 are provided with a sliding groove on the side facing the inside of the diamond-shaped frame structure; the degradation reinforcement includes a reinforcing seat 705 that slides along the sliding groove; and the reinforcing seat 705 is provided with a raised reinforcing strip 707.

[0037] It should be further explained that the hollowed-out 704 and the groove are alternating and parallel strip structures.

[0038] It should be further explained that a lead screw 706 driven to rotate by a motor is provided in the slide groove; a moving block threadedly connected to the lead screw 706 is provided on the back side of the reinforcing seat 705; and multiple sets of reinforcing bars 707 are provided on the front side of the reinforcing seat 705.

[0039] It should be further noted that the cutting disc 703 is set at the top and bottom of the four sides of the rhomboid frame structure, corresponding to the feeding and discharging directions.

[0040] When the rhomboid frame structure repeatedly compresses and flips the biomass waste, the sliding and mutual compression of the surrounding reinforcing seats 705 enhances the effect on the biomass waste. The cutting disc 703 cuts the biomass waste on the outside of the rhomboid frame structure, comprehensively assisting in degradation.

[0041] like Figure 8 As shown, a pressurized steam generator 2 has a pressurized steam outlet nozzle 201 positioned at the center of one side of its extension into the steam chamber; the driving component 9 is configured as cylinder 2, with multiple sets arranged along the outer periphery of the pressurized steam outlet nozzle 201, acting on the translational pushing component 6; the biological material is heated by saturated steam (pressure 1.2-2.0 MPa), and then instantly depressurized, using the pressure difference to trigger an "explosion" effect that destroys the fiber structure. The pressurized steam outlet nozzle 201 is made of corrosion-resistant ceramic material, ensuring rapid pressure release (pressure drop of 2-13 bar).

[0042] like Figures 9-10 As shown, the translational pushing assembly 6 includes a piston frame 608 that moves along the inner wall of the degradation chamber via a piston rod connected to cylinder two; a rotary drive seat 607 is provided in the middle of the piston frame 608, and a piston ring 602 is connected to its outer periphery via a sealing plate 604; a piston disc 601 is provided on the side facing the rhomboid frame structure, which rotates along the inner wall of the piston ring 602 via the rotary drive seat 607; a rotary drive seat 605 is provided at the center of the piston disc 601, and a vent 603 is provided on its outer periphery; two sets of opposing connecting frames 701 are connected one-to-one to the rotation shaft of the corresponding side drive seat 605; the vent 603 and the sealing plate 604 are arranged one-to-one, and when they are opposite each other, the vent 603 is completely covered by the sealing plate 604, and when they are staggered, the vent 603 is open.

[0043] It should be further explained that the rotary drive base 1 607 and the rotary drive base 2 605 are equipped with motor drive structures, which respectively drive the piston disc 601 and the two sets of opposite connecting frames 701 to rotate.

[0044] It should be further explained that the piston disc 601, piston holder 608, sealing plate 604, rotary drive seat one 607 and rotary drive seat two 605 form a multi-layer perforated structure.

[0045] When the piston disc 601 rotates until the vent 603 is aligned with the sealing plate 604, the vent 603 is completely covered by the sealing plate 604, sealing the piston disc 601. This seals both the steam chamber and the degradation chamber. The movement of the piston disc 601 allows for the pushing and pulling of the two opposing connecting frames 701 from both sides, causing deformation of the rhomboid frame structure. It also pushes the biomass that has fallen to the bottom of the degradation chamber into the rhomboid frame structure. After preheating to the set temperature, the piston disc 601 rotates until the vent 603 intersects with the sealing plate 604, opening the vent 603. High-temperature, high-pressure steam enters the degradation chamber. During this process, the deformation and rotation of the rhomboid frame structure repeatedly compresses and agitates the biomass waste, further promoting degradation.

[0046] It should be further explained that an annular pressure relief pipe 609 is provided inside the piston ring 602; the pressure relief pipe 609 is connected to a pressure relief head with a valve, and simultaneously connected to a pressure relief valve 5 via an air pipe 606; the pressure relief head is embedded in the sealing plate 604 and connects to the degradation chamber. In the later stage of degradation, the piston disc 601 is rotated to reseal it, and the pressure relief valve 5 connects to the degradation chamber. Then, the two sets of piston discs 601 are moved relative to each other, increasing the pressure by compressing air on the one hand, and further squeezing the biomass inside the rhomboid frame structure on the other. Subsequently, the pressure relief head is opened to release pressure instantaneously, using the pressure difference to trigger an "explosion" effect that destroys the fiber structure.

[0047] like Figure 11 As shown, the feeding component 4 includes a feeding box 401; the bottom of the feeding box 401 is provided with a feeding port 402 that connects to the degradation chamber and has a sealed door, and multiple sets of cutting rollers 403 are provided inside; before the biomass waste enters the degradation chamber, the cutting rollers 403 cut and refine it to accelerate the subsequent degradation efficiency.

[0048] like Figure 12 As shown, the discharge component 3 includes a discharge box; the top of the discharge box is provided with a discharge port 301 that connects to the degradation chamber and has a sealed door, the side wall is provided with a gas-liquid pipe 302, and the bottom is provided with a detachable discharge seat 303; the products of biomass waste degradation include gas (e.g., carbon monoxide), solid (e.g., biochar), and liquid (e.g., phenolic compounds), which can be discharged separately through the gas-liquid pipe 302 and the discharge seat 303, facilitating product classification and recycling.

[0049] Example 2: Based on the biomass waste degradation equipment in Example 1, this example proposes a biomass waste degradation method, the steps of which are as follows:

[0050] S1. Start the heating degradation tank 1 and the pressurized steam generator 2 to begin preheating and generating steam; biomass waste enters the feed box 401, is cut and refined by the cutting roller 403, enters the degradation chamber through the feed port 402, and falls into the diamond-shaped frame structure.

[0051] S2. The piston rod of cylinder 802 extends and retracts synchronously, pushing and pulling two sets of opposing connecting frames 701 from the front and rear sides. The piston disc 601 moves, pushing and pulling two sets of opposing connecting frames 701 from the left and right sides, causing the rhomboid frame structure to deform continuously. Under heating conditions, the internal biomass is repeatedly squeezed. The reinforcing seats 705 around the perimeter enhance the effect on biomass waste, while the cutting blade 703 cuts the biomass waste on the outside of the rhomboid frame structure, comprehensively assisting in degradation. By crushing biomass, the physical barriers and chemical structure of biomass are destroyed, thereby significantly improving degradation efficiency.

[0052] S3. During the above-mentioned crushing and extrusion process, the rhomboid frame structure rotates, flips, and combines with the crushed biomass waste to promote its dispersion and crushing.

[0053] S4. After preheating to the set temperature, the piston disc 601 rotates until the vent 603 and the sealing plate 604 are intersected, and the vent 603 is open; high-temperature and high-pressure steam enters the degradation chamber to continue processing the biomass;

[0054] S5. The piston disc 601 rotates until the vent 603 is opposite to the sealing plate 604. The vent 603 is completely covered by the sealing plate 604. The two sets of piston discs 601 move relative to each other, increasing the pressure by compressing air and adjusting the pressure. At the same time, the biomass inside the rhomboid frame structure is further squeezed. The biomass is heated by saturated steam (pressure 1.2-2.0MPa).

[0055] S6. Once the pressure reaches the threshold, open the pressure relief head to release pressure instantly (pressure drop of 2-13 bar), using the pressure difference to trigger an "explosion" effect that destroys the fiber structure.

[0056] S7. After degradation is completed, the products of biomass waste degradation are discharged through gas-liquid pipe 302 and discharge seat 303 respectively.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
