Description
An automated sorting and recycling system for biomass waste in a zero-carbon industrial park Technical Field
[0001] This invention relates to the field of waste sorting and resource recycling technology, specifically to an automatic sorting and recycling system for biomass waste in a zero-carbon industrial park. Background Technology
[0002] With the advancement of zero-carbon industrial park construction, these parks should improve their solid waste and resource utilization facilities, implement waste sorting systems, and enhance their sorting and processing capabilities. However, current waste sorting often relies on manual labor or single technologies, resulting in low accuracy. A large amount of waste still ends up in landfills or incineration, causing energy waste and carbon emissions. In particular, biomass waste such as fruit peels and fallen leaves generated within the parks traditionally requires external transportation for processing, increasing transportation energy consumption and carbon footprint. Existing technologies typically separate sorting from resource recovery, lacking a comprehensive solution that combines high-precision automated sorting with on-site biomass resource recovery.
[0003] Therefore, existing technologies have shortcomings and need to be improved and developed. Summary of the Invention
[0004] This invention provides an automated sorting and recycling system for biomass waste in zero-carbon industrial parks. It addresses the shortcomings of existing waste sorting technologies, which often rely on manual labor or single technologies, resulting in low sorting accuracy and a large amount of waste still ending up in landfills or incineration, leading to energy waste and carbon emissions. Specifically, biomass waste such as fruit peels and fallen leaves generated within the park traditionally requires external transportation for processing, increasing transportation energy consumption and carbon footprint.
[0005] This invention provides an automatic sorting and recycling system for biomass waste in a zero-carbon industrial park, comprising: a waste sorting system, a waste treatment system, a storage system, and a cleaning system;
[0006] The waste sorting system includes a sorting chamber, which comprises a biomass waste chamber and a recyclable waste chamber symmetrically distributed on both sides. A light sensor is installed at 80% of the height of the biomass waste chamber wall. A photovoltaic panel is rotatably connected to the top of the sorting chamber, and the photovoltaic panel is electrically connected in sequence to a photovoltaic combiner box and a photovoltaic controller. The photovoltaic controller is electrically connected to an energy storage battery. An AI camera and a robotic arm are installed between the photovoltaic panel and the top of the sorting chamber. After the AI camera captures and identifies the types of waste located inside the sorting chamber, the robotic arm is used to sort the biomass waste and recyclable waste.
[0007] The waste treatment system includes a crushing chamber, a drying chamber, and a degradation chamber. The bottom of the biomass waste chamber is connected to the crushing chamber and is equipped with a sealing cover. After the biomass waste passes through the crushing chamber, the drying chamber, and the degradation chamber in sequence, filtrate and biomass fertilizer are produced.
[0008] The storage system includes a filtrate tank for receiving filtrate and a biomass fertilizer storage tank for receiving biomass fertilizer.
[0009] The cleaning system includes a water collection ditch, in which a rainwater storage tank is arranged. A water pump is installed in the rainwater storage tank. When the water pump pumps water, the water in the rainwater storage tank enters the sorting chamber through the inlet pipe and is used to rinse the sorting chamber through the spray pipe. The bottom of the sorting chamber is connected to the water collection ditch through the outlet pipe.
[0010] Furthermore, a rotating component is fixedly connected to each of the top two sides of the sorting cavity. Each rotating component includes a first motor, a push rod, a slide rail groove, and a support rod. The first motor is connected to one end of the push rod to push the push rod to slide on the slide rail groove under electric drive. The other end of the push rod is connected to the support rod, and the other end of the support rod is fixed to the photovoltaic panel. The bottom of the photovoltaic panel is rotatably connected to the sorting cavity. When the push rod slides on the slide rail groove, the support rod is used to drive the photovoltaic panel to rotate.
[0011] Furthermore, the top of the biomass waste chamber and the top of the recyclable material chamber are both equipped with sealing covers. Each sealing cover includes a second motor, a rotating rod, a roller shutter panel, and several rollers. Several rollers are fixed to the top of both the biomass waste chamber and the recyclable material chamber, and each roller is rotatably connected to one of the rollers. A second motor is fixed to the left side of the biomass waste chamber and the right side of the recyclable material chamber, respectively. The rotating shaft of each second motor is connected to the rotating rod, and when the second motor is started, it drives the rotating rod to rotate. The roller shutter panel rotates and is stored on the rotating rod. When the second motor is started, the rotating rod rotates to move the roller shutter panel onto the rollers to cover the biomass waste chamber and the recyclable material chamber, respectively.
[0012] Furthermore, the pulverizing chamber is arranged below the biomass waste chamber, and the interior of the pulverizing chamber is equipped with a dual-axis shearing blade for pulverizing the biomass waste to a particle size of 2-3 mm; the bottom of the pulverizing chamber is sloping and is equipped with an electric push rod, which is used to push the pulverized biomass waste to the drying chamber.
[0013] Furthermore, a drum dryer is installed inside the drying chamber. The feed inlet of the drum dryer is connected to the bottom of the crushing chamber, and the discharge outlet of the drum dryer faces the bottom of the drying chamber. The body of the drum dryer is covered with PTC heating elements. The body of the drying chamber is covered with bismuth telluride thermoelectric generators, which are electrically connected to the energy storage battery. The bottom of the drying chamber is sloping and is equipped with an electric push rod, which is used to push the dried biomass waste to the degradation chamber.
[0014] Furthermore, the top of the degradation chamber is connected to the bottom of the drying chamber. The degradation chamber is a constant-temperature fermentation chamber and is pre-filled with a composite microbial community. A third motor is installed inside the degradation chamber, and the shaft of the third motor is connected to an L-shaped stirring tooth. When the third motor is started, the L-shaped stirring tooth is used to mix biomass waste with the composite microbial community. The degradation chamber is also connected to an aeration pipe that connects the inside and outside of the chamber. A blower is installed at the end of the aeration pipe. An oxygen concentration sensor is also installed on the top of the degradation chamber.
[0015] Furthermore, the top of the filtrate tank is connected to the bottom of the lower side of the degradation chamber via a first pipe to receive the filtrate produced during fermentation in the degradation chamber. A filter screen is fixed to the pipe opening on one side of the degradation chamber. The bottom of the filtrate tank is connected to a filtrate fertilizer pipe, which is equipped with a valve. The end of the filtrate fertilizer pipe is above the ground and connected to a spray head.
[0016] Furthermore, the wall of the biomass fertilizer storage tank is connected to the bottom of the lower side of the degradation chamber via a second pipe. An electric push rod is arranged at the bottom of the degradation chamber. After the degradation chamber has fermented, the electric push rod is used to push the solid through the second pipe into the biomass fertilizer storage tank. A biomass fertilizer storage chamber for receiving biomass fertilizer is arranged inside the biomass fertilizer storage tank. A fourth motor and a fixed pulley are fixed outside the biomass fertilizer storage tank. One end of the sling is fixed to the biomass fertilizer storage chamber, and the other end of the sling is connected to the shaft of the fourth motor via the fixed pulley so that the sling is retracted and the biomass fertilizer storage chamber is lifted under the drive of the fourth motor.
[0017] Furthermore, the rainwater storage tank has H-shaped filter components that are fixed to each other on both sides of the tank wall and the tank top. The filter components are, from left to right, a first filter layer, a second filter layer and a third filter layer. The bottom of the first filter layer and the bottom of the third filter layer are fixed to the bottom of the water collection ditch. A soil layer is arranged on the second filter layer, and plants are planted in the soil layer.
[0018] Furthermore, a third pipe is connected between the bottom of the rainwater storage tank and the filtrate tank, and a valve is installed on the third pipe; a filtrate concentration sensor is installed at the bottom of the filtrate tank.
[0019] Beneficial effects:
[0020] As can be seen from the above technical solutions, the present invention provides an automatic sorting and recycling system for biomass waste in zero-carbon industrial parks, which has the following beneficial effects:
[0021] 1. Precise and efficient sorting: Equipped with AI cameras and robotic arms, the AI cameras utilize their infrared high-definition cameras and AI recognition modules to integrate multi-dimensional data such as visible light and infrared images for waste identification, improving the accuracy of waste sorting and effectively reducing human intervention and sorting errors. The robotic arm automatically places the identified waste into the corresponding chamber, and an electric sealing cover prevents the spread of odors.
[0022] 2. On-site utilization of biomass: For sorted biomass waste, this invention completes resource utilization within the park through crushing, drying, and fermentation. The dual-axis shearing blades crush the biomass to 2-3mm; PTC heating elements utilize the system's own heat to reduce the moisture content to below 50%; then, in a constant-temperature aerobic fermentation chamber at 30-35℃, a complex microbial community including cellulose-degrading bacteria and acid-producing bacteria is added for 72 hours of degradation, ultimately producing humus-rich organic fertilizer. This process avoids carbon emissions from off-site processing while simultaneously recycling the energy and nutrients in the biomass within the park.
[0023] 3. Achieved complete energy self-sufficiency: Photovoltaic panels are installed, and bismuth telluride thermoelectric generators are attached to the drying chamber to generate electricity based on temperature differences. During the day, the electricity generated by the photovoltaic panels and thermoelectric generators meets the operational needs of each unit in the system, and excess electricity is stored in energy storage batteries. The bismuth telluride thermoelectric generators effectively utilize the temperature difference between the drying chamber and the external environment, significantly reducing dependence on the external power grid and indirect carbon emissions.
[0024] 4. A closed-loop resource recycling system is achieved: The filtrate produced during fermentation is sprayed onto the park's lawns and green spaces through filtrate fertilization pipes, where plants fix carbon dioxide through photosynthesis; the biomass fertilizer can be further processed into biochar for soil improvement, achieving carbon sequestration. By converting biomass waste into energy, producing fertilizer, and using it as plants, a complete closed loop is formed, significantly improving the material cycling efficiency and carbon sequestration capacity of the park's ecosystem.
[0025] 5. Improved cleanliness and hygiene: Water pumps and spray pipes are used to rinse the interior walls of each sorting compartment. The rinsing water comes from a rainwater storage tank, and the wastewater after rinsing is filtered and purified for recycling, avoiding the generation of odors from long-term garbage storage, ensuring the cleanliness and hygiene of the garbage storage area, and reducing the system's water consumption and carbon emissions.

[0039] In existing technologies, with the advancement of zero-carbon park construction, parks should improve solid waste and resource utilization facilities, implement waste sorting systems, and enhance sorting and processing capabilities. However, current waste sorting often relies on manual labor or single technologies, resulting in low sorting accuracy. A large amount of waste still ends up in landfills or incineration, causing energy waste and carbon emissions. In particular, biomass waste such as fruit peels and fallen leaves generated within the parks traditionally requires external collection and processing, increasing transportation energy consumption and carbon footprint. Existing technologies typically separate sorting from resource recovery, lacking a holistic solution that combines high-precision automatic sorting with on-site biomass resource recovery.
[0040] In view of this, embodiments of the present invention provide an automatic sorting biomass waste recycling and treatment system for zero-carbon industrial parks, as shown in FIG1, including: a waste sorting system, a waste treatment system, a storage system and a cleaning system.
[0041] Referring to Figure 2, the waste sorting system includes sorting chambers, which include a biomass waste chamber 1 and a recyclable waste chamber 2 symmetrically distributed on the left and right sides. A light sensor 3 is installed at 80% of the height of the wall of the biomass waste chamber 1. A photovoltaic panel 4 is rotatably connected to the top of the sorting chamber. The photovoltaic panel 4 is electrically connected to a photovoltaic combiner box and a photovoltaic controller in sequence. The photovoltaic controller is electrically connected to an energy storage battery 5. An AI camera 6 and a robotic arm 7 are installed between the photovoltaic panel 4 and the top of the sorting chamber. After the AI camera 6 captures and identifies the types of waste inside the sorting chamber, the robotic arm 7 is used to sort the biomass waste and recyclables.
[0042] Photovoltaic power generation, combined with the thermoelectric power generation of the pulverizing chamber 8, stores the electricity in the energy storage battery 5, providing power for the electrical equipment in the automatically sorted biomass waste recycling and treatment system of the zero-carbon park.
[0043] The sorting chamber can be made of straw fiber reinforced bio-based composite material with an overall modular design. AI camera 6 and robotic arm 7 are positioned at the bin's inlet between the photovoltaic panel 4 and the top of the sorting chamber. AI camera 6 uses an AI infrared high-definition camera to capture images of the waste's appearance. Simultaneously, the camera's built-in AI recognition module fuses multi-dimensional data through deep learning algorithms, achieving high-precision identification of waste types, typically with an accuracy rate of ≥95%. The robotic arm 7 then sorts the waste into the corresponding bins. Finally, the sealing cover of the corresponding chamber opens, completing the waste sorting process.
[0044] Referring to Figure 5, the waste treatment system includes a crushing chamber 8, a drying chamber 9, and a degradation chamber 10. The bottom of the biomass waste chamber 1 is connected to the crushing chamber 8, and a sealing cover is installed at the connection between the biomass waste chamber 1 and the crushing chamber 8. After the biomass waste passes through the crushing chamber 8, the drying chamber 9, and the degradation chamber 10 in sequence, filtrate and biomass fertilizer are produced.
[0045] The storage system includes a filtrate tank 11 for receiving filtrate and a biomass fertilizer storage tank 12 for receiving biomass fertilizer.
[0046] Referring to Figures 1 and 6, the cleaning system includes a water collection ditch, within which a rainwater storage tank 13 is arranged. The water collection ditch is arranged around the rainwater storage tank 13 to facilitate better accumulation of rainwater during heavy rains. A water pump 14 is installed inside the rainwater storage tank 13. When the water pump 14 pumps water, the water in the rainwater storage tank 13 enters the sorting chamber through the inlet pipe 15 and is used to rinse the sorting chamber through the spray pipe 16. The bottom of the sorting chamber is connected to the water collection ditch through the outlet pipe 17.
[0047] The water pump 14 delivers water from the rainwater storage tank 13 to the spray pipes 16 on the inner wall of the sorting chamber. The spray pipes 16 can be installed at the four corners of the chamber or on the chamber wall. The spray pipes 16 can spray water in 360° to rinse the inner wall of the chamber from all directions. The drain hole is located at the bottom of the chamber and is connected to the water collection ditch. Through filtration by the third filter layer, the water resources are recycled.
[0048] In some embodiments, referring to Figure 3, a rotating component is fixedly connected to each of the top two sides of the sorting cavity. Each rotating component includes a first motor 18, a push rod, a slide rail groove 19, and a support rod 20. The first motor 18 is connected to one end of the push rod to push the push rod to slide on the slide rail groove under electric drive. The other end of the push rod is connected to the support rod 20, and the other end of the support rod 20 is fixed to the photovoltaic panel 4. The bottom of the photovoltaic panel 4 is rotatably connected to the sorting cavity. When the push rod slides on the slide rail groove, the support rod 20 drives the photovoltaic panel 4 to rotate. In some other embodiments, a waste disposal port is provided on the outer surface of the sorting cavity, away from the position of the robotic arm 7. A light sensor 3 is installed on the inner surface of the sorting cavity, directly opposite the waste disposal port. When waste is detected being disposed of from the waste disposal port, the photovoltaic panel 4 is activated after signal transmission processing.
[0049] In some embodiments, referring to FIG4, a sealing cover is installed on the top of the biomass waste chamber 1 and the top of the recyclable waste chamber 2. The sealing cover includes a second motor 21, a rotating rod 22, a roller shutter 23, and several rollers 24. Several rollers are fixed on the top of both the biomass waste chamber 1 and the recyclable waste chamber 2, and each roller 24 is rotatably connected to a roller. A second motor 21 is fixed on the left side of the biomass waste chamber 1 and the right side of the recyclable waste chamber 2, respectively. The rotating shaft of each second motor 21 is connected to the rotating rod 22. When the second motor 21 is started, it is used to drive the rotating rod 22 to rotate. The roller shutter 23 is rotated and stored on the rotating rod 22. When the second motor 21 is started, the rotating rod 22 rotates to move the roller shutter 23 onto the rollers 24 to cover the biomass waste chamber 1 and the recyclable waste chamber 2, respectively.
[0050] In some embodiments, referring to Figures 1 and 5, the pulverizing chamber 8 is arranged below the biomass waste chamber 1. The interior of the pulverizing chamber 8 is equipped with a dual-axis shearing blade 25 for pulverizing biomass waste to a particle size of 2-3 mm. The bottom of the pulverizing chamber 8 is sloping and is equipped with an electric push rod, which is used to push the pulverized biomass waste to the drying chamber 9.
[0051] In some embodiments, referring to Figures 1 and 5, a drum dryer 26 is installed inside the drying chamber 9. The feed inlet of the drum dryer 26 is connected to the bottom of the crushing chamber 8, and the discharge outlet of the drum dryer 26 faces the bottom of the drying chamber 9. The body of the drum dryer 26 is covered with PTC heating elements to reduce the moisture content of the crushed biomass waste to below 50%. The body of the drying chamber 9 is covered with a bismuth telluride thermoelectric generator 27, which is electrically connected to the energy storage battery 5. The bottom of the drying chamber 9 is sloping and is equipped with an electric push rod, which is used to push the dried biomass waste to the degradation chamber 10.
[0052] In some embodiments, referring to Figures 1 and 5, the top of the degradation chamber 10 is connected to the bottom of the drying chamber 9. The degradation chamber 10 is a constant-temperature fermentation chamber and is pre-filled with a composite microbial community. The constant-temperature fermentation chamber provides temperature and an aerobic environment, controlling the temperature within the range of 30~35℃ for aerobic fermentation. The composite microbial community includes at least cellulose-decomposing bacteria and acid-producing bacteria. The biomass waste is degraded for 72 hours using the constant-temperature fermentation chamber and the composite microbial community to generate biomass fertilizer rich in humus. A third motor 28 is installed inside the degradation chamber 10. The shaft of the third motor 28 is connected to an L-shaped stirring tooth 29. When the third motor 28 is started, the L-shaped stirring tooth 29 is used to mix the biomass waste with the composite microbial community. The degradation chamber 10 is also connected to an aeration pipe 30 that connects the inside and outside of the chamber. A blower 31 is installed at the end of the aeration pipe 30. An oxygen concentration sensor 32 is also installed on the top of the degradation chamber 10.
[0053] In some embodiments, referring to Figure 1, the top of the filtrate tank 11 is connected to the bottom of the lower side of the degradation chamber 10 via a first pipe 33 to receive the filtrate produced during fermentation in the degradation chamber 10. A filter screen is fixed to the opening of the first pipe 33 on one side of the degradation chamber 10. A filtrate fertilization pipe 35 is connected to the bottom of the filtrate tank 11, and a valve is installed on the filtrate fertilization pipe 35. The end of the filtrate fertilization pipe 35 is above the ground and connected to a spray head 36. In some embodiments, referring to Figure 1, a third pipe 42 is connected between the bottom of the rainwater storage tank 13 and the filtrate tank 11, and a valve is installed on the third pipe 42. A filtrate concentration sensor 43 is installed at the bottom of the filtrate tank 11.
[0054] The filtrate tank 11 receives the filtrate produced during the fermentation process. The amount of water entering the filtrate tank 11 from the rainwater storage tank 13 is controlled by the valve on the third pipe 42, thereby diluting the filtrate in the filtrate tank 11. The filtrate fertilizer pipe 35 can be controlled by the valve to fertilize the surrounding grassland regularly.
[0055] In some embodiments, referring to Figures 1 and 5, the wall of the biomass fertilizer storage tank 12 is connected to the bottom of the lower side of the degradation chamber 10 via a second pipe 34. An electric push rod is arranged at the bottom of the degradation chamber 10. After the degradation chamber 10 has fermented, the electric push rod is used to push the solid through the second pipe 34 into the biomass fertilizer storage tank 12. A biomass fertilizer storage chamber 37 for receiving biomass fertilizer is arranged inside the biomass fertilizer storage tank 12. A fourth motor 38 and a fixed pulley 39 are fixed outside the biomass fertilizer storage tank 12. One end of the sling 40 is fixed to the biomass fertilizer storage chamber 37, and the other end of the sling 40 is connected to the shaft of the fourth motor 38 via the fixed pulley 39 so that the sling 40 is retracted and the biomass fertilizer storage chamber 37 is lifted under the drive of the fourth motor 38.
[0056] The biomass fertilizer storage tank 12 can be lifted to the ground via a fixed pulley 39 and a sling 40, which facilitates the subsequent production of biomass fertilizer into biomass carbon and achieves carbon sequestration.
[0057] In some embodiments, referring to FIG1, the two side walls and the top of the rainwater storage tank 13 are equipped with filter components 41 that are fixed to each other and are in an H-shape. The filter components 41 are, from left to right, a first filter layer, a second filter layer and a third filter layer. The bottom of the first filter layer and the third filter layer are fixed to the bottom of the water collection ditch. A soil layer is arranged on the second filter layer, and plants are planted in the soil layer.
[0058] When a zero-carbon industrial park uses an automated sorting and recycling system for biomass waste, the following steps are completed:
[0059] I. Waste Sorting and Management:
[0060] (1) Automatic sorting operation: When users throw away garbage, the AI infrared high-definition camera at the disposal port collects the appearance of the garbage and infrared data. After the AI module merges the data, it judges the type of garbage and drives the robotic arm 7 to move the biomass garbage. If the peel or leaves are moved to the top of the biomass garbage chamber 1, the corresponding sealing cover will open to unload the material. Recyclable materials, such as metal and plastic, will be classified into the recyclable material chamber 2.
[0061] (2) Overflow management: When the light sensor 3 detects that the filling amount in the biomass waste chamber 1 reaches 80% of the height of the biomass waste chamber 1, the subsequent waste treatment process is triggered; when the recyclable material chamber 2 is overflowing, data can be transmitted through another light sensor 3 to send a cleaning reminder to the park management platform.
[0062] II. Implementation of on-site biomass treatment:
[0063] (1) Crushing stage: The bottom partition of the biomass waste chamber 1 is pulled out, and the biomass waste falls into the crushing chamber 8 below. The dual-shaft shearing blades 25 crush it to a diameter of 2-3 mm, which is convenient for subsequent degradation.
[0064] (2) Drying process: The crushed waste enters the drying chamber 9, and the heat generated by the subsequent energy conversion unit is used to reduce the moisture content of the waste to below 50% through the drum dryer 26 and PTC heating elements, in preparation for degradation.
[0065] (3) Aerobic degradation stage: After drying, the waste enters the constant temperature fermentation chamber and a compound microbial community is introduced. Oxygen is supplied through blower 31 and aeration pipe in an environment of 30~35℃. At the same time, the third motor 28 is started periodically according to the working conditions to make the L-shaped stirring teeth 29 rotate to prevent the biomass waste from caking. Degradation is completed within 72 hours to generate semi-finished biomass fertilizer. The filtrate produced by fermentation is introduced into the filtrate tank 11 for temporary storage.
[0066] III. Implementation of Biomass Fertilizer Application and Carbon Sequestration
[0067] (1) Filtration fertilization: The filtrate in the filtrate tank 11 is diluted with water in the rainwater storage tank 13 and then automatically fertilized to the surrounding grassland through the spray head 36 at regular intervals to enhance the grassland's purification capacity.
[0068] (2) Solid fertilizer treatment: The biomass fertilizer that has been degraded is stored in the biomass fertilizer storage tank 12. When the biomass fertilizer storage tank 12 is full, the biomass fertilizer on the biomass fertilizer storage bin 37 is lifted to the ground by the fixed pulley 39 and the sling 40. After manual transfer, it is made into biochar, which is used for soil improvement in the park or for special storage to achieve carbon sequestration; it can also be used directly for plant cultivation in the park to help plants absorb carbon dioxide through photosynthesis.
[0069] IV. Implementation of Automatic Cleaning:
[0070] (1) Chamber cleaning: Periodically or when odor or bacteria exceedance is detected in the chamber, the water pump 14 draws water from the rainwater storage tank 13 and washes the inner wall of the chamber 360° through the spray pipes 16 at the four corners of the chamber; after rinsing, the drain hole discharges the wastewater into the collection ditch, and after purification, it flows back to the rainwater storage tank 13 for recycling.
