[0019] Advantages:

[0020] From the above technical solution, the application provides an automatic classification biomass garbage recycling system for a zero-carbon park, which has the following advantages:

[0021] 1. High accuracy and efficiency of classification: AI cameras and mechanical hands are equipped, the infrared high-definition camera and AI recognition module of the AI camera are used, multi-dimensional data such as visible light and infrared images are fused for garbage identification, the accuracy of garbage classification is improved, and manual intervention and classification errors are effectively reduced. The mechanical hand automatically puts the identified garbage into the corresponding chamber, and the electric sealing cover prevents odor from spreading.

[0022] 2. Biomass is utilized on site: for the classified biomass garbage, the application completes resource processing inside the park through crushing, drying, and fermentation. The double-shaft shearing blade crushes the biomass to 2-3mm; the PTC heating sheet reduces the moisture content to below 50% using the heat generated by the system itself; then in the 30-35℃ constant-temperature aerobic fermentation bin, add cellulose-degrading bacteria and acid-producing bacteria and other complex microbial flora for 72 hours of degradation, finally generate organic fertilizer rich in humus. This process avoids carbon emissions from external processing, and at the same time, the energy and nutrients in the biomass are left in the park for recycling.

[0023] 3. Achieve complete energy self-sufficiency: install photovoltaic panels and attach bismuth telluride thermoelectric power generation sheets on the cabin of the drying bin for thermoelectric power generation. The electric energy generated by the photovoltaic panels and the thermoelectric power generation together during the day meets the operating requirements of each unit of the system, and the excess electric energy is stored in the energy storage battery. The bismuth telluride thermoelectric power generation sheet generates electricity through temperature difference, which can effectively utilize the temperature difference between the drying bin and the external environment, greatly reducing the dependence on external power grid and indirect carbon emissions.

[0024] 4. Achieve resource recycling closed loop: the filtrate produced by fermentation is sprayed to the lawn and green land in the park through the filtrate fertilization pipeline, and plants fix carbon dioxide through photosynthesis; biomass fertilizer can be further made into biomass charcoal for soil improvement after being taken out, realizing carbon sequestration. Through energy conversion, fertilizer production, and plant use, biomass garbage realizes carbon sequestration, forms a complete closed loop, and greatly improves the material circulation efficiency and carbon sink capacity of the park 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.

[0058] When the automatic classification biomass waste recycling system is used for waste treatment in the zero-carbon park, the following steps are completed:

[0059] I. Waste classification and management:

[0060] (1) Automatic classification operation: when the user puts in the waste, the AI infrared high-definition camera at the waste inlet collects the appearance and infrared data of the waste. The AI module fuses the data to judge the type of the waste, and drives the mechanical hand 7 to move the biomass waste, such as fur and leaves, to the above of the biomass waste cavity 1, and the corresponding sealing cover is opened to unload; recyclable materials, such as metal and plastic, are put into the recyclable material cavity 2.

[0062] II. Implementation of biomass in-situ treatment:

[0063] (1) Crushing link: the partition plate at the bottom of the biomass waste cavity 1 is pulled out, and the biomass waste falls into the lower crushing bin 8. The double-shaft shearing blade 25 crushes the biomass waste to a diameter of 2-3 mm, facilitating subsequent degradation.

[0064] (2) Drying link: the crushed waste enters the drying bin 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 roller dryer 26 and the PTC heating sheet, preparing for degradation.

[0065] (3) Aerobic degradation link: the dried waste enters the constant-temperature fermentation bin, and the compound microbial flora is put in. Oxygen is supplied through the air blower 31 and the aeration pipe in an environment of 30-35℃. The third motor 28 is started periodically according to the working condition to make the L-shaped stirring teeth 29 rotate, preventing the biomass waste from being hardened. The degradation is completed within 72 hours, and the semi-finished biomass fertilizer is generated. The filtrate generated by fermentation is temporarily stored in the filtrate tank 11.

[0066] III. Biomass Fertilizer Application and Carbon Sequestration Implementation

[0067] (1) Fertilizer application: The filtrate in the filtrate tank 11 is diluted by the water in the rainwater storage tank 13, and then automatically applied to the surrounding grass through the spray head 36 at regular intervals, improving the purification capacity of the grass.

[0068] (2) Solid fertilizer treatment: The degraded biomass fertilizer 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 through the fixed pulley 39 and the sling 40, and then manually transported to produce biomass charcoal, which is used for soil improvement in the park or stored specially to achieve carbon sequestration; it can also be directly used for plant cultivation in the park to help plants absorb carbon dioxide through photosynthesis.

[0069] IV. Automatic cleaning implementation:

[0070] (1) Chamber cleaning: The water pump 14 draws water from the rainwater storage tank 13 to flush the inner wall of the chamber through the spray pipe 16 at the four corners of the chamber at regular intervals or when the chamber detects unusual odors or excessive bacteria; after flushing, the waste water is discharged into the water collection ditch and then returned to the rainwater storage tank 13 for recycling after purification.

[0071] V. During the operation of the system, the photovoltaic panel 4 absorbs solar energy to generate electricity, and the thermoelectric power piece on the outer wall of the drying bin 9 utilizes the drying heat and the temperature difference with the environment to generate electricity. The two kinds of electric energy are preferentially supplied to each unit of the device, and the excess electric energy is stored in the energy storage battery 5 to ensure the normal operation of the device on cloudy days or at night.
