Description

[Technical field]

[0001] The present disclosure relates to a biofuel production vehicle, a biofuel production system, and a biofuel production method. [Background technology]

[0002] As a measure against the depletion of fossil fuels and global warming caused by CO2 emissions, it has been proposed to turn biomass, such as woody biomass, which has traditionally been treated as waste, into a resource and make effective use of it. For example, sawmills and timber markets generate large amounts of bark. In forests, parks, and rivers, mowing and pruning generate large amounts of branches and leaves. By collecting these instead of disposing of them and turning them into resources by producing biofuels such as biochar, it is possible to reduce waste disposal costs and CO2 emissions.

[0003] However, such biomass materials, such as wood and branches and leaves, are widely scattered throughout the country. Therefore, it is desirable to efficiently recover and recycle such biomass materials. For example, Patent Document 1 discloses a mobile carbonization treatment facility in which a compact carbonization treatment facility is mounted on a vehicle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6233910 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the mobile carbonization treatment facility disclosed in Patent Document 1 is merely a compact carbonization device mounted on a vehicle, and no consideration is given to the utilization of the energy generated in the carbonization treatment facility.

Effect of the Invention

[0013] According to the biofuel production vehicle, biofuel production system, and biofuel production method disclosed herein, it is possible to effectively utilize the energy generated in the biofuel production process. [Brief description of the drawings]

[0014] [Figure 1] 1 is a diagram showing a schematic configuration of a biofuel production vehicle according to an embodiment of the present disclosure. FIG. [Diagram 2] FIG. 1 is a diagram illustrating an example of a vehicle electrical system according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of a biofuel production vehicle, a biofuel production system, and a biofuel production method according to the present disclosure will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a biofuel production vehicle 1 according to this embodiment. As shown in FIG. 1, a biofuel production vehicle 1 is equipped with a biofuel production system 2 that produces biofuel from a biomass feedstock. The biofuel production vehicle 1 may also be equipped with a conveyor (raw material conveying means) 3 as raw material conveying means for supplying the biomass raw material to the biofuel production system 2.

[0016] The biofuel production vehicle 1 may also be equipped with a crane 4. The crane 4 is used, for example, to carry biomass raw materials into the biofuel production system 2. The crane 4 is also used to carry out the biofuel produced by the biofuel production system 2. For example, a cage is connected to the tip of the crane 4 via a wire, and the biomass raw materials and biofuel are stored in the cage, thereby carrying in the biomass raw materials and carrying out the biofuel. The biofuel production vehicle 1 is also provided with a drone port (not shown) that functions as a takeoff and landing base for the drone (aircraft) 5. The drone port is provided with a drone charging device 41 (see FIG. 2) for charging the drone 5. The drone 5 acquires, for example, information on the collection site of the biomass raw material (location information of the collection site, topographical information, etc.), information on carbon fixation (information on the collected amount of the biomass raw material, location information of the fixed biochar, composition information of the biochar, information on the amount of the spread of the biochar, etc.). For example, the drone 5 is used to fly around the vehicle and search for biomass raw material in the vicinity. The drone 5 is also used to search for a place where carbon is fixed by spreading the biofuel (biochar) produced by the biofuel production system 2. For example, the drone 5 collects the biomass raw material and transports it to the biofuel production vehicle 1. For example, the drone 5 transports the biochar from the biofuel production vehicle 1 to a destination (for example, farmland, etc.) where the carbon is to be fixed in order to spread the biochar.

[0017] The biofuel production system 2 includes, for example, a drying device 11, a pulverizer 12, a pyrolysis furnace 13, and a combustion chamber 14. The drying device 11 dries, for example, the biomass raw material fed from the conveyor 3. The biomass raw material is, for example, woody biomass (biological resource) made of wood, forest residues such as branches and leaves generated during tree felling and lumber processing, bark generated from sawmills, wood pellets and wood chips generated from bark and sawdust, etc. For example, a belt dryer that dries the biomass raw material placed on a belt by contacting it with high-temperature gas can be used as the drying device 11. Also, instead of a belt dryer, a rotary kiln dryer, a disk dryer, or the like can be used as the drying device 11. The heating method of the drying device 11 may be either indirect heating or direct heating.

[0018] The pulverizer 12 pulverizes the dried biomass raw material into particles of an appropriate size. The pulverizer 12 is also configured to be capable of pulverizing biofuels such as biochar produced in a pyrolysis furnace. The pyrolysis furnace 13 generates biofuel such as biochar by pyrolyzing the biomass raw material. The pyrolysis furnace 13 includes a combustion chamber 14. A part of the biomass raw material pulverized by the pulverizer 12 is fed into the combustion chamber 14 as a raw material for combustion. The combustion chamber 14 burns the biomass raw material. The pyrolysis furnace 13 indirectly heats the biomass raw material with heat supplied from the combustion chamber 14, causing pyrolysis and gasification reactions. As the pyrolysis progresses, the biomass raw material is carbonized while generating pyrolysis gas. The generated biofuel (e.g., biochar, etc.) is discharged and stored in, for example, a predetermined storage container (not shown). Also, the biofuel such as biochar may be stored in the storage container after being pulverized by the pulverizer 12 as described above. The heating method of the pyrolysis furnace 13 may be either indirect heating or direct heating. Examples of the pyrolysis furnace 13 include an indirect heating rotary kiln, a direct heating rotary kiln, a fluidized bed furnace, and a screw-type carbonization furnace.

[0019] Furthermore, known techniques may be appropriately adopted for various operating conditions (e.g., drying temperature, drying time, pulverized particle size, pyrolysis temperature, time, oxygen concentration, etc.) of the biofuel production system 2 described above. Control of the biofuel production system 2 (e.g., various controls of the drying device, pulverizer, and pyrolysis furnace) is performed by a system control device 45 (see FIG. 2). Furthermore, the configuration of the biofuel production system 2 is just an example, and known devices can be appropriately applied.

[0020] The combustible gas (pyrolysis gas) generated in the pyrolysis furnace 13 is supplied to a power generation device 15. Also, a configuration may be adopted in which a part of the combustible gas is returned to the combustion chamber 14 and used as fuel for combustion. The power generating device 15 generates power using combustible gas. The power generating device 15 includes, for example, a micro gas turbine 16 and a generator 10 connected to the micro gas turbine 16. When combustible gas is supplied to the micro gas turbine 16, the micro gas turbine 16 rotates, and the rotational power is transmitted to the generator 10 to generate power. The generated power of the generator 10 is supplied as drive power for on-board devices (various electrical devices) provided in the biofuel production vehicle 1. Details will be described later.

[0021] It should be noted that known technology can be applied to the power generation device 15. For example, instead of the micro gas turbine 16, a gas engine, a fuel cell, or the like may be used.

[0022] Moreover, the heat generated in the pyrolysis furnace 13 and the heat generated in the combustion chamber 14 are supplied to the drying device 11 through the heat flow path 18. This allows heat to be transferred to the drying device 11, thereby making it possible to improve the drying efficiency. Heat can be supplied to the drying device 11 by directly guiding the combustion gas generated in the combustion chamber 14 to the drying device 11, or by using water or steam heated by heat exchange with the combustion gas, or other heat medium.

[0023] Fig. 2 is a diagram showing an example of an electrical system diagram of the biofuel production vehicle 1 according to this embodiment. As shown in Fig. 2, a generator 10 is connected to an in-vehicle power system 20, and an in-vehicle device 40 is also connected to the in-vehicle power system 20. The power generated by the generator 10 is used as a power source for the on-vehicle device 40. The on-vehicle device 40 includes, for example, at least one of a drone charging device 41, a crane driving motor 42, a conveyor driving motor 43, a crusher driving motor 44, a system control device 45, and the like. 2, the on-board device 40 is directly connected to the on-board power system 20, but this is not limited to the example. For example, a switch, a power conversion device, etc. may be provided between the on-board power system 20 and various electric devices constituting the on-board device 40.

[0024] The drone charging device 41 is provided, for example, in a drone port (not shown) and charges the drone 5 with power supplied via the in-vehicle power system 20. The crane drive motor 42 is a motor for driving the crane 4 , the conveyor drive motor 43 is a motor for driving the conveyor 3 , and the crusher drive motor 44 is a motor for driving the crusher 12 . The system control device 45 is a system for controlling the biofuel production system 2, and includes, for example, an information processing device, a display, and other electric devices. The on-vehicle device 40 may also include a component analyzer, a measuring instrument, various measuring instruments, and the like, used for biomass raw materials, biofuels, various gases, and the like.

[0025] In addition, a power storage device 30 is connected to the in-vehicle power system 20. The power storage device 30 stores the power generated by the generator 10 and discharges the power when the load is high to supplement the power generated by the generator 10. In addition, if the biofuel production vehicle 1 is a vehicle that runs on electricity, such as an electric vehicle, the vehicle may be configured to use the power of the generator 10 and the power of the power storage device 30 to run the vehicle.

[0026] Next, a method of using the biofuel production vehicle 1 according to this embodiment will be described. The biofuel production vehicle 1 travels around the generating site of the biomass raw material and collects the biomass raw material. The collected biomass raw material is fed by the conveyor 3 into the biofuel production system 2, specifically, into the drying device 11. At this time, if the generator 10 is not generating electricity, for example, the conveyor drive motor 43 is supplied with electricity from the on-board power storage device 30 to drive the conveyor 3.

[0027] Furthermore, at a predetermined timing, the combustion chamber 14 of the pyrolysis furnace 13 is ignited and combusted. As a result, heat from the combustion chamber 14 is supplied to the pyrolysis furnace 13. This heat is also transferred to the drying device 11 through the heat flow path 18, thereby assisting the drying of the drying device 11. Note that until the fuel to be combusted in the combustion chamber 14 (part of the biomass raw material or the combustible gas generated in the pyrolysis furnace 13) is supplied, a startup fuel (for example, liquefied biofuel or biogas filled in a container) may be used.

[0028] The biomass raw material dried by the drying device 11 is fed into the pulverizer 12. The pulverizer 12 pulverizes the biomass raw material. At this time, when the generator 10 is not generating electricity, power is supplied from the on-board power storage device 30 to the pulverizer drive motor 44 to drive the pulverizer 12. A part of the biomass raw material pulverized by the pulverizer 12 is supplied to the combustion chamber 14 as fuel, and the remainder is supplied to the pyrolysis furnace 13 as a raw material for biofuel production. The order in which the drying device 11 and the pulverizer 12 process the biomass raw material may be reversed; that is, the biomass raw material pulverized by the pulverizer 12 may be fed into the drying device 11 and dried.

[0029] In the pyrolysis furnace 13, the biomass raw material is pyrolyzed to generate biofuel such as biochar, and combustible gas (carbonized gas) is also generated. This combustible gas is supplied to the power generation device 15. In addition, a part of the combustible gas may be returned to the combustion chamber 14 and used as fuel for combustion. The power generation device 15 generates power using combustible gas, and the generated power is supplied to the in-vehicle device 40 via the in-vehicle power system 20. In addition, when the generated power is insufficient, the power storage device 30 supplies the insufficient power to the in-vehicle device 40. Biofuels such as biochar produced by the biofuel production system 2 are collected in a designated collection container.

[0030] As described above, the biofuel production vehicle 1 according to this embodiment is equipped with a biofuel production system 2 that produces biofuel from biomass raw materials, and is equipped with a power generation device 15 that generates electricity using combustible gas generated in the biofuel production system 2, and the electricity generated by the power generation device 15 can be supplied as driving power for the on-board device 40. In addition, according to the biofuel production vehicle 1 of this embodiment, a portion of the biomass raw material is supplied to the combustion chamber 14 as fuel, and the heat generated by burning the biomass raw material is supplied to the drying device 11 as a heat source through the heat flow path 18.

[0031] This allows for effective use of energy generated during the biofuel production process. As a result, for example, it becomes unnecessary to supply power via a cable from outside the vehicle or to replenish fuel via a pipeline while the biofuel production system 2 is in operation. In this way, it becomes possible to operate the biofuel production system 2 and produce biofuel while receiving as little energy as possible from the outside. In other words, it becomes possible to provide an autonomous mobile biofuel production system that reduces the supply of external energy as much as possible.

[0032] In the above embodiment, the case where the pulverizer 12 is provided as the processing device for finely grinding the biomass raw materials has been described as an example, but the present invention is not limited to this. For example, a cutter for cutting the biomass raw materials may be used instead of the pulverizer 12. In this case, the generated power of the generator 10 is supplied to a cutter drive motor for driving the cutter.
