Description

Technical Field

[0001] This utility model relates to the field of biomass waste reduction and treatment technology, specifically to a small-scale carbonization device for biomass waste. Background Technology

[0002] Returning crushed straw to the field is not ideal, as it presents problems such as slow decomposition, pests and diseases, and nitrogen fixation. Burning straw remains a practical choice for many farmers, and it is difficult to completely prohibit it.

[0003] Carbon-based compound fertilizers can slow down the leaching, volatilization, and concentrated absorption of nutrients, improving soil porosity, pH, moisture content, and microbial ecology. Using agricultural and forestry waste to produce carbon as the matrix for compound fertilizers not only reduces carbon emissions and air pollution from straw burning, but also helps reduce the overuse of chemical fertilizers, gradually addressing issues such as soil structural imbalance, water pollution, and agricultural product quality.

[0004] Currently, there is a lack of economically viable biomass waste carbonization equipment. The carbonization processes disclosed in patents CN118085908A, CN117487577A, CN116376578A, and CN107541227A utilize fixed equipment, are technologically advanced, have high resource utilization rates, and use diverse raw materials. However, both raw materials and products require long-distance transportation, making them suitable for large farms, forest farms, and livestock areas.

Specifically, the recovery unit 50, located on the top surface of the heat-conducting shell 80 and connected to the interior of the heat-conducting shell 80, can return the separated fuel gas to the insulation box 30 for combustion.

[0063] The recovery unit 50 includes a collection pipe 51, a condensation tower 52, a return gas pipe 53, several combustion pipes 54, a discharge pipe 55, and a liquid collection tank 56.

[0064] One end of the collecting pipe 51 passes through the top surface of the insulation box 30 and connects to the two aforementioned outlets on the top surface of the heat-conducting shell 80, thereby connecting to the interior of the heat-conducting shell 80. The other end of the collecting pipe 51 connects to the inlet of the condensing tower 52. The condensing tower 52 is equipped with multi-stage fractionation plates or multi-layer packing, using air or water as a refrigerant to cool the effluent from the carbonization chamber 40 and separate liquid and gaseous components. The liquid collection tank 56 is used to collect the liquid components obtained by the condensing tower 52. The return gas pipe 53 is used to send the fuel gas obtained by the condensing tower 52 into the combustion chamber 301. All combustion pipes 54 are located in the combustion chamber 301 and connected in parallel to the end of the return gas pipe 53, and are equipped with multiple fuel gas nozzles to uniformly heat the bottom surface of the heat-conducting shell 80 with the combustion fuel gas.

[0070] One end of the flue pipe 61 is connected to the air inlet of the exhaust fan 62. The other end of the flue pipe 61 is connected to the two flue gas outlets of the flue gas passage 302.

[0071] The exhaust pipe of the exhaust fan 62 has one branch leading to the spray tower, and a spare branch for connecting to a straw combustion flue gas treatment device disclosed in CN103894054A / 2014. The aforementioned spare branch can also be connected to a temporarily prepared loose soil pile, thereby simplifying the treatment of flue gas in the event of water shortage.

[0072] The spray tower is used to spray the treatment liquid to purify the flue gas. Water tank 61 is used to store water. The water in water tank 63 is used for preparing the treatment liquid, cooling the condenser tower 52, and for counterweighting the mobile carbonization equipment.

[0077] Four load cells 78 are respectively installed at the four corners of the bottom surface of the vehicle-mounted bracket 20 and electrically connected to the main controller to monitor load changes of the mobile carbonization equipment. When load monitoring is not required, the main controller controls the hydraulic mechanism of the trailer 10 to lift the vehicle-mounted bracket 20, thereby protecting the load cells 78.

[0078] This mobile carbonization equipment allows for intermittent carbonization to process biomass waste, such as field straw. The intermittent carbonization method includes the following steps.

[0079] S10. Feeding Procedure

[0080] Open the rear door 33 and the bin door 41, and put the straw into the carbonization bin 40 in a measured amount. Then close the bin door 41 and the rear door 33. Open the side door 31 and put an appropriate amount of straw into the combustion chamber 301.

[0081] S20. Startup Procedure

[0082] Close the regulating valve of the return gas pipe 53, open the switch valve of the exhaust pipe 55, ignite the straw in the combustion chamber 301, and continuously supply straw to the combustion chamber 301. When the internal temperature of the heat-conducting shell 80 reaches 250 degrees Celsius, open the regulating valve of the return gas pipe 53 and close the switch valve of the exhaust pipe 55 to allow the gas to enter the combustion chamber 301. When the internal temperature reaches 500 degrees Celsius, the supply of straw to the combustion chamber 301 can be stopped.

[0083] S30 Maintenance Steps

[0084] Adjust the gas supply and straw supply in the combustion chamber 301 to maintain the internal temperature of the heat-conducting shell 80 within the range of 400~600 degrees Celsius for 0.5~3 hours, and then stop the gas supply and straw supply in the combustion chamber 301.

[0085] S40. Discharge Steps

[0086] Remove more than half of the rear length of the carbonization chamber 40 from the insulation box 30. Open the unloading door located outside the insulation chamber and unload the carbonized straw from the carbonization chamber 40. Then, completely return the carbonization chamber 40 to the insulation box 30. While removing the carbonization chamber 30, turn on the water pump to spray water and cool the hot carbonized straw. After unloading the carbonized straw, continue to spray water to cool it down. The adsorbed water content of the carbonized straw should be controlled to avoid affecting subsequent straw return to the field.

[0087] The technical advantages of this mobile carbonization equipment are:

[0088] 1) The carbonization chamber is removable. The top of the carbonization chamber is open, the rear side is the chamber door, and the bottom is equipped with a discharge door. Materials can be fed from the open or the chamber door, and materials can be discharged from the chamber door and the discharge door. There are multiple operating methods. It can carbonize various wastes from farmland, forest land and grassland, as well as treat powdery industrial waste.

[0089] 2) It adopts an integrated combustion chamber and flue gas passage. The combustion chamber is located below the heat-conducting shell, and the flue gas passage surrounds the front, left, right and top surfaces of the heat-conducting shell. It has high heat transfer efficiency, and the heat transfer route is similar to that of traditional charcoal burning devices. Environmental pollution is controllable, the performance is reliable, the operation is simple, and it is conducive to promotion in rural markets.

[0090] 3) The total assembly weight can be controlled between 3 and 8 tons. When used with small harvesters, small charcoal fertilizer manufacturing equipment and small seeding agricultural machinery for on-site operation in the fields, it can shorten the organic compound fertilizer technology chain, reform the organic compound fertilizer industry model, and promote the application of science and technology services in rural areas. It is suitable for the current agricultural situation in many regions at home and abroad.

[0091] Example 2

[0092] Another mobile carbonization device for processing biomass waste has been disclosed.

[0093] This mobile carbonization equipment is based on Example 1, with the following improvements.

[0095] Four load cells 78 are distributed and mounted at the bottom corners of the insulation box 30, and are electrically connected to the main controller to monitor the load changes of the insulation box 30.

[0096] Other aspects of this mobile carbonization equipment are basically the same as those in Example 1.

[0097] Example 3

[0099] The vehicle-mounted carbonization equipment is based on Example 1, with the following improvements.

[0100] Remove trailer 10, hoist it onto the transport vehicle before use, and unload it from the transport vehicle after use.

[0101] Other aspects of this mobile carbonization equipment are basically the same as those in Example 1.

[0102] In other embodiments, the insulation box, heat-conducting shell, and carbonization chamber are all pentagonal, hexagonal, octagonal, elliptical, or deformed cylindrical shapes with flattened bottoms, and the outer surface of the heat-conducting shell is provided with fins or textured surfaces. This structure can reduce the height of the insulation box and increase the heat exchange area of ​​the heat-conducting shell.

[0103] In other embodiments, the flue gas escaping from the flue gas outlet is piped into a temporarily prepared loose soil pile or water tank. This structure allows for simple flue gas treatment using a temporary soil pile or water tank. That is, in the mobile (or vehicle-mounted) carbonization equipment, the purification unit 60 of Embodiment 1 can be replaced by a temporary soil pile or water tank.

[0104] In another embodiment, the carbonization chamber does not have an unloading door, and the pipeline on the top of the insulation box has a flexible hose with redundant length; during unloading, the front of the insulation box is lifted by a hydraulic mechanism, allowing the carbonized material to pour out from the carbonization chamber door.

[0105] In another embodiment, the portion of the water spray pipe with spray holes is located below the rear door. This structure allows for water spraying to cool the high-temperature carbonized material during and after unloading. Regardless of the method used for water spraying, the adsorbed water content of the carbonized material must be controlled to avoid affecting subsequent carbonized material treatment processes.

[0106] In other embodiments, the aforementioned mobile (or vehicle-mounted) carbonization equipment is used to process other biomass waste, such as forest waste, autumn and winter pasture waste, sawdust, and paper scraps. The specific carbonization process and start-up steps, and the solid fuel used, should be adapted to the specific scenario.

Simple modifications and equivalent transformations to the embodiments are all within the above-mentioned scope of protection.
