Description

Technical Field

[0001] This invention relates to the field of biomass carbonization / pyrolysis technology, specifically a trailer-mounted mobile straw carbonization system. Background Technology

[0002] Straw carbonization is a thermochemical conversion process that transforms straw into biochar. Specifically, it involves converting straw into biochar through pyrolysis (decomposition under high temperature and oxygen deficiency). This process can simultaneously achieve carbon sequestration and pollutant separation, and has multiple benefits such as resource utilization, carbon sequestration and emission reduction, and soil improvement.

[0003] In existing technologies, straw carbonization processes are mostly designed as follows: raw material pretreatment → carbonization reaction → product collection and treatment → exhaust gas purification and energy recovery → biochar application. The carbonization reaction stage promotes the release of volatiles from straw through high temperatures, typically above 200℃. Before reaching the desired temperature, a gradual heating process is necessary. Studies have shown that controlling the heating rate at 10-20℃ / min is more conducive to the formation of biochar pore structures. During the heating process, due to the low reaction temperature, the exhaust gas composition is relatively complex, containing not only combustible gases such as CO, H2, and CH4, but also wood acetate, tar, and soot. However, after reaching the desired temperature, due to complete pyrolysis, the exhaust gas composition essentially no longer contains wood acetate and tar. In the product collection and processing stage, condensation towers are often used to separate tar and wood vinegar. Tar can be used as fuel, while wood vinegar can be used for agricultural antibacterial purposes or as organic fertilizer. In the exhaust gas purification and energy recovery stage, the exhaust gas from the carbonization reaction is usually treated with dust removal before the combustible gas is returned to the carbonization system as fuel for the heating system.

[0004] In known straw carbonization technologies, the treatment methods for exhaust gas are not differentiated between the heating process and the stage of reaching the desired temperature; all stages use the same gas path for exhaust gas treatment. For example, a mobile, small-scale, continuous self-heating straw carbonization device disclosed in Chinese invention patent CN117025238B uses exhaust gas containing soot and combustible gases, which enters the induced draft fan assembly valve through the flue gas outlet. The induced draft fan provides power, sending the soot to the flue gas conveying system, then into the carbon dioxide absorption system. In the carbon dioxide absorption system, carbon dioxide, tar, and soot are absorbed, while combustible gases and water vapor are discharged into a dust-free biogas conveying pipe, then into the biogas drying system. In the biogas drying system, water vapor is absorbed, and finally, the dried combustible gas is sent to the gas collection system. The gas collection system valve connects to the gas inlet, providing a heat source for the gas heating assembly, thus achieving self-heating in the straw pyrolysis carbonization process.

[0005] It is worth noting that in the above-mentioned known straw carbonization technologies, after the carbonization reaction reaches the desired temperature, the exhaust gas components of the carbonization reaction basically no longer contain lignin and tar, and there is no need to recover lignin and tar. The original gas path will become too long, resulting in increased heat loss in the exhaust gas, which is not conducive to heat recovery. Summary of the Invention

[0006] This invention aims to optimize the gas path structure in straw carbonization technology by implementing different gas paths for the heating process and the stage of reaching the desired temperature in the carbonization reaction, thereby improving the efficiency of exhaust gas purification and energy recovery and reducing heat loss in the exhaust gas.

[0034] Please see Figures 1 to 7 As shown, in one embodiment, a trailer-type mobile straw carbonization system of the present invention includes a trailer 1, on which a carbonization reaction unit 2 is installed. The carbonization reaction unit 2 includes a furnace body 21. The outer shell of the furnace body 21 has a heat insulation layer 211. The internal space of the furnace body 21 is partitioned at the top to form a carbonization chamber 22, and the bottom is empty to serve as a combustion chamber 23 for heating the carbonization chamber 22. The carbonization chamber 22 is fitted with the inner wall of the furnace body 21 on the left and right sides and the top surface, thereby forming a flue 24 communicating with the combustion chamber 23.

[0035] The rear end of the carbonization chamber 22 is provided with a material inlet and outlet 221, and the rear end of the furnace body 21 is provided with a furnace door 25 for opening and closing the material inlet and outlet 221.

[0036] An air supply pipe 231 is laid horizontally inside the combustion chamber 23. The air supply pipe 231 has multiple air outlets arranged axially (not shown in the figure). The front end of the air supply pipe 231 extends outward through the furnace body 21 to form an air inlet 233. A fan 3 is provided on the trailer 1 to supply air to the air inlet 233.

[0037] The combustion chamber 23 is also equipped with a combustible gas return pipe 234 located above the air supply pipe 231. The combustible gas return pipe 234 has multiple combustible gas outlets arranged axially (not shown in the figure). The front section of the combustible gas return pipe 234 extends outward through the furnace body 21 to form a combustible gas inlet 236.

[0038] The front end of the furnace body 21 is provided with a first flue gas outlet 230 that connects to the combustion chamber 23 and a first pyrolysis gas outlet 220a that connects to the carbonization chamber 22. The top of the furnace body 21 has a second flue gas outlet 240 that connects downward to the top of the flue 24 and a second pyrolysis gas outlet 220b that connects downward to the top of the carbonization chamber 22.

[0039] A fireproof door 27 for opening and closing the combustion chamber 23 is provided on the left side of the furnace body 21;

[0040] The trailer 1 is also equipped with a condenser tower 4 and a water tank 5. A first gas path is constructed for the carbonization chamber 22 through pipelines, which passes through the first pyrolysis gas discharge port 220a, the condenser tower 4 and the water tank 5 in sequence; a second gas path passes through the second pyrolysis gas discharge port 220b, the condenser tower 4 and the water tank 5 in sequence; a third gas path passes through the second pyrolysis gas discharge port 220b and the combustible gas inlet 236 in sequence; and a fourth gas path is constructed for the combustion chamber 23 through pipelines, which passes through the first exhaust port 230, the condenser tower 4 and the water tank 5 in sequence; and a fifth gas path passes through the second exhaust port 240, the condenser tower 4 and the water tank 5 in sequence. Each of the first, second and third gas paths is equipped with a gas valve to open or close the gas path.

[0041] In the fifth gas path, a heat exchange unit 6 is connected in series between the second exhaust port 240 and the condenser tower 4. The heat exchange unit 6 has a branch port 61 that connects to the air inlet 233 of the fan 3.

[0042] In the above embodiments, the present invention operates as follows:

[0043] (1) Open the furnace door 25 and fill the carbonization chamber 22 with straw to be carbonized through the inlet and outlet 221. After filling, close the furnace door 25 to seal the inlet and outlet 221.

[0044] (2) Open the fire door 27, load the initial fuel into the combustion chamber 23, ignite the initial fuel, close the fire door 27, and the flue gas generated in the combustion chamber 23 enters the fourth and fifth gas paths. After being sprayed and filtered by the condenser tower 4, it is then filtered by the water tank 5 and discharged into the atmosphere.

[0045] (3) The carbonization chamber 22 is heated by the combustion chamber 23, and the temperature inside the carbonization chamber 22 gradually increases, entering the heating process in the carbonization reaction process;

[0046] (4) During the heating process in the carbonization reaction, the third gas path is closed by the gas valve and the first and second gas paths are opened. The straw to be carbonized in the carbonization chamber 22 begins to generate pyrolysis gas rich in wood acetate and tar. The pyrolysis gas enters the first and second gas paths and is sprayed and filtered by the condenser tower 4. The wood acetate and tar in the pyrolysis gas are absorbed in the condensate water and recovered. The remaining gas is then filtered by the water tank 5 and discharged into the atmosphere.

[0047] (5) After the temperature inside the carbonization chamber 22 exceeds 200℃, the carbonization reaction reaches the desired temperature, and the pyrolysis gas basically no longer contains wood acetic acid and tar. The first and second gas paths are closed by the gas valve, and the third gas path is opened. The high-temperature pyrolysis gas flows directly back to the combustion chamber 23 through the third gas path, which not only achieves the supply of fuel gas but also fully retains the heat energy in the exhaust gas. At the same time, the flue gas produced in the combustion chamber 23 also contains more waste heat. In the fifth gas path, the flue gas is diverted by the heat energy exchange unit 6, and one path of flue gas... After being sprayed and filtered by the condenser tower 4, the flue gas is then filtered by the water bath in the water tank 5 before being discharged into the atmosphere. Another stream of flue gas is connected to the air inlet 233 of the fan 3 through the diversion port 61 of the heat exchange unit 6, thereby mixing with the air supplied by the fan 3 to the air inlet 233. This results in the air supplied by the fan 3 to the air inlet 233 having a higher initial temperature, thus achieving heat recovery. With the assistance of the heat recovery unit in the fifth gas path, the exhaust gas heat recovery rate of the combustion chamber 23 and the carbonization chamber 22 can be increased by 20%.

[0048] (6) After the straw in the carbonization chamber 22 has been carbonized, it can be cooled and the furnace door 25 can be opened to recover the biochar.

[0049] In the above embodiments, the trailer-type mobile straw carbonization treatment system of the present invention is integrated on the trailer 1 and can be moved under the drive of the tractor, which can significantly reduce the collection and transportation costs of straw.

[0050] In the above embodiment, the initial fuel introduced into the combustion chamber 23 can be an appropriate amount of wood or other fuels, such as tar separated from the condensate.

[0051] In the above embodiments, the method of probing the internal temperature of the carbonization chamber 22 can be based on experience evaluation, or a temperature sensor can be implanted in the carbonization chamber 22. The selection of these probing methods is not the direction of improvement of the present invention, and can be implemented directly according to known technical means, so they will not be elaborated.

[0052] In the above embodiment, the spray water for the condenser tower 4 is provided by the water tank 5. The specific water circuit connection is a conventional setting and will not be described in detail.

[0053] In an improved embodiment, to facilitate the inspection and cleaning of the flue 24, inspection doors 28 for opening and closing the flue 24 are respectively provided on the left and right sides of the furnace body 21. During inspection and cleaning, opening the inspection doors 28 exposes the flue 24, making it easy to clean the interior of the flue 24 using a high-pressure water gun. Of course, a corresponding drain outlet is provided at the bottom of the combustion chamber 23 to prevent water accumulation.

[0054] In another improved embodiment, to enhance the thermal efficiency of the carbonization chamber 22, a ceramic heat storage plate 241 is provided on the inner wall of the carbonization chamber 22. The ceramic heat storage plate 241 is a known porous ceramic heat storage body. During the heating process, the ceramic heat storage plate 241 can not only accumulate a large amount of heat, but also generate a large amount of far-infrared rays, which will increase the thermal efficiency of the carbonization chamber 22 by about 20-30%.

[0055] In another improved embodiment, the lower end of the condenser tower 4 is provided with a guide port 41, and the trailer 1 is provided with a recovery tank 42 for collecting the liquid discharged from the guide port 41. The condensate that has absorbed wood vinegar and tar is discharged into the recovery tank 42 through the guide port 41. After standing in the recovery tank 42, the mixture separates into layers, and the upper layer of wood vinegar and the lower layer of tar can be obtained.

[0056] In another improved embodiment, in order to facilitate the feeding of straw and the recycling of biochar, the carbonization chamber 22 is equipped with a material cart 7 that can enter and exit through the inlet and outlet 221.

[0057] Specifically, the inner bottom of the carbonization chamber 22 is equipped with a slide rail 222 perpendicular to the inlet / outlet 221. The bottom of the material cart 7 slides into the carbonization chamber 22 via the slide rail 222. A support 71 is also provided at the bottom of the rear of the material cart 7, with the upper end of the support 71 hinged to the bottom of the material cart 7. When the material cart 7 moves outside the carbonization chamber 22, the support 71 naturally hangs down and unfolds to support the ground. When the material cart 7 retracts into the carbonization chamber 22, the support 71 folds back into the bottom of the material cart 7. With the material cart 7 in place, the fire door 27 is opened, the material cart 7 is pulled out of the carbonization chamber 22, and the straw to be carbonized is loaded into the material cart 7. After loading, the material cart 7 is pushed back into the carbonization chamber 22, and then the furnace door 25 is closed. Similarly, after carbonization is complete, the fire door 27 is opened, the material cart 7 is pulled out of the carbonization chamber 22, and the biochar can be recovered.

[0058] To shorten the cooling time after carbonization, in an improved embodiment of the present invention, a water supply pipe 215 is provided on the furnace body 21 above the furnace door 25. The water supply pipe 215 has multiple downward-extending spray nozzles 216. A water pump 8 is provided on the trailer 1 to supply water from the water tank 5 to the water supply pipe 215. A water valve 217 is connected in series between the water supply pipe 215 and the water pump 8. As the material cart 7 slides out from the inlet / outlet 221, the water pump 8 is started and the water valve 217 is opened, spraying the biomass char in the material cart 7 with the spray nozzles 216 to cool it down. This spray cooling method can accelerate the cooling rate of the biomass char and avoid the inner wall of the carbonization chamber 22 being sprayed, thereby preventing the inner wall of the carbonization chamber from being deformed and damaged due to a sudden drop in temperature. As for the water sprayed into the material cart 7, most of it vaporizes and evaporates at high temperature, preventing a large amount of water from accumulating in the material cart 7.

[0059] In another improved embodiment, the trailer 1 is equipped with a weighing device 11 for measuring its own weight. Optionally, the weighing device 11 has a pressure sensor (not shown) mounted on the axle of the trailer 1. The pressure sensor generates a signal change through the pressure exerted on the axle by the trailer body, and then obtains the weight of the trailer 1 through a corresponding circuit. The significance is that the biomass carbon conversion rate can be calculated by the change in the weight of the trailer 1.

[0060] In another improved embodiment, the trailer 1 is also equipped with a positioning device 12 connected to a satellite navigation system. The positioning device 12 is used to record the work location and can be used in conjunction with an APP for Internet of Things management.

[0061] Specifically, both the weighing device 11 and the positioning device 12 can be directly implemented according to the technical solutions known in the prior art. Therefore, the specific implementation methods will not be described in detail in this invention.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
