Description

[Technical field]

[0001] This invention relates to a regional resilience system used in a business model that utilizes abandoned and unused forest resources, which are considered to be one of the most representative regional resources, to supply electricity that can be used at least in the event of a disaster to nearby businesses and homes, thereby contributing to regional disaster prevention measures. [Background technology]

[0002] Traditionally, in the event of a disaster, the power supply to businesses and homes in the affected area is cut off, making it difficult to carry out business activities or even maintain one's livelihood. This is a well-known serious risk in daily life, even without waiting for the example of the Great East Japan Earthquake. Improving and strengthening the constitution of such disaster-vulnerable areas is an extremely essential element in ensuring good business activities and maintaining one's livelihood.

[0003] Meanwhile, in recent years, efforts to strengthen the aforementioned regions have also been accompanied by a movement toward decarbonization. From this perspective, unused regional resources such as wood scraps, pruning branches, and agricultural residues can be used as raw materials and carbonized to produce charcoal, which can not only be used as an alternative to fossil fuels and to improve soil, but can also contribute to the sequestration and storage of carbon dioxide.

[Figure 6] FIG. 2 is a diagram illustrating a schematic configuration of the power storage station illustrated in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, an embodiment of a community resilience system according to the present invention will be described with reference to the accompanying drawings.

[0027] FIG. 1 is a system diagram showing the system configuration of one embodiment of this regional resilience system S.

[0028] As shown in Figure 1, this community resilience system S is characterized by comprising: a storage station S10 for collecting and storing local materials such as thinned wood, bamboo, and pruned branches that are used for charcoal production; a secondary combustion type charcoal production device S12 into which the local materials (not shown) stored in the storage station S10 are input and indirectly heated using a primary combustion burner to produce charcoal, and which burns the gas generated during charcoal production using a secondary combustion burner, the secondary combustion type charcoal production device S12 having an exhaust port for discharging exhaust gas after secondary combustion; a heat exchanger S14 for generating high-pressure, high-temperature steam using the heat in the exhaust exhausted from the exhaust port of the charcoal production device S12; a power generation device S16 for generating steam electricity using the steam generated by the heat exchanger S14; and a power storage station S18 having a plurality of batteries for storing electricity generated by the electricity generated by the power generation device S16, the batteries being removable.

[0029] In this way, by configuring the regional resilience system S shown in FIG. 1, during normal times (i.e., when no disaster has occurred), the charcoal produced by the secondary combustion charcoal making device S12 is supplied to the region S20 as charcoal for BBQ, soil conditioner, water purifier, etc., and the region S20 is revitalized from the viewpoint of increasing its economic power. At the same time, at least in the event of a power outage (i.e., when the power supply from the power company is stopped) to the region during a disaster, the heat generated by the heat exchanger S14, which is provided in the power storage station S18 and uses the heat in the exhaust gas exhausted from the exhaust port of the charcoal making device S12 to generate high-pressure, high-temperature steam, is used to generate steam. The batteries that have been stored in the power generation device S16 that supplies electricity to the area are removed and distributed to homes, stores, and businesses S20 in the surrounding area to be used as emergency power sources. Furthermore, when the electricity in the distributed batteries is used up and the remaining electricity is depleted, the used batteries are collected and recharged at the power storage station S18. By redistributing the charged batteries to the homes, stores, and businesses S20 in the surrounding area, it is possible to contribute to the economic activity of the area S20 under normal circumstances, and it is also possible to avoid power outages in the area S20 in response to a disaster, thereby contributing to the resilience of the area S20 from the perspective of protecting the lives of people in the area S20.

[0030] In this power storage station S18, the power generation capacity of the steam power generation device S16 does not need to be particularly large, and in particular does not need to have a function for rapid charging. In a situation where a large number of batteries need to be provided according to the number of local residents and the number of stores and businesses, these can be divided into a number of groups, and for each group, a number of batteries appropriate to the power generation capacity of the power generation device S16 can be set, and power can be stored in the batteries for each group sequentially over time.

[0031] In the community resilience system S configured as above, in addition to the above-mentioned system configuration, a hot spring well S22 from which hot spring water springs up may be further provided. In this way, if there is a hot spring well S22 gushing out in the community, it can be incorporated into the system S and used to strengthen the community. Specifically, the hot spring well S22 is connected to the power generation device S16, and this power generation device S16 can generate power by further using the hot spring heat from the hot spring water gushing out from the hot spring well S22. In this way, in the community resilience system S, the hot spring heat from the hot spring water gushing out from the hot spring well S22 can be utilized to contribute to power generation in the power generation device S16, thereby making it possible to reliably strengthen the community.

[0032] In addition, this regional resilience system S further includes a secondary heat exchanger S24 that exchanges (gas / liquid) the remaining heat from the exhaust gas generated in the secondary combustion carbonization device S12, which is used for heat exchange (gas / steam) into high-temperature, high-pressure steam in the heat exchanger S14 and is used for power generation in the power generation device S16, and can be effectively used for other equipment that requires heat. Specifically, the regional resilience system S may further include a heating and cooling device S26 that cools and heats hot water, and the heating and cooling device S26 can receive heat from the secondary heat exchanger S24 and use it for the heating and cooling device S26 that cools and heats hot water, thereby improving the heating and cooling efficiency in the region and thereby resilience of the region. The regional resilience system S may further include a greenhouse cultivation device S28 that heats the inside. This will revitalize greenhouse cultivation in the region and thereby strengthen the regional economy.

[0033] Also, a land-based aquaculture apparatus S30 may be further provided, which uses the remaining heat generated by the heat exchanger S14 after use in the power generation apparatus S16 to heat the culture water into which the fish are released. In this way, the remaining heat after use in the power generation apparatus S16 can be utilized to heat the culture water in the land-based aquaculture apparatus S30, thereby improving the efficiency of the land-based aquaculture apparatus S30 in the region and thereby strengthening the region.

[0034] In the regional resilience system S configured as described above, the main components of the system S shown in Figure 1 will be explained in order below.

[0035] First, the configuration of the secondary combustion carbonization apparatus S12 for carbonizing local materials such as thinned wood, bamboo, and pruned branches stored in the storage station S will be described with reference to Figs. 2 to 4. Fig. 2 is a front cross-sectional view of the secondary combustion carbonization apparatus S12 (i.e., a cross-sectional view taken along line II-II in Fig. 3), Fig. 3 is a side cross-sectional view of the secondary combustion carbonization apparatus S12 taken along line III-III in Fig. 2, and Fig. 4 is a process operation diagram showing the operating state of the secondary combustion carbonization apparatus S12. In this embodiment, the secondary combustion carbonization apparatus S12 is a dry heat waste volume reduction treatment apparatus (product name "Meltkin") manufactured by Daiso Co., Ltd. TIFF2025003239000002.tif12165 is used.

[0036] As shown in Figures 2 and 3, this secondary combustion carbonization device S12 is basically composed of a carbonization chamber 1 that constitutes a carbonization mechanism that indirectly heats local materials containing moisture, evaporating the moisture in the local materials, and carbonizing the local materials by drying them, a stirrer 2 that constitutes a stirring mechanism that stirs the local materials while they are being dried in the carbonization chamber 1, a connecting passage 17 that is connected to the carbonization chamber 1 and for extracting the steam / moisture evaporated from the local materials to the outside of the carbonization chamber 1, and a secondary combustion chamber 18 that is connected to the outlet of the connecting passage 17 and constitutes a secondary combustion mechanism that combusts the steam / moisture extracted from the outlet of the connecting passage 17 to deodorize the odorous components contained in the steam / moisture.

[0037] As shown in FIG. 3, the agitator 2 constituting the agitation mechanism includes a triangular agitator blade rotatably stored in the carbonization chamber 1, an agitator shaft 3 to which the agitator blade is integrally attached, a gear 4 coaxially fixed to one end of the agitator shaft 3, a drive motor 6, and a chain 5 that endlessly connects the drive shaft j of the drive motor 6 and the gear.

[0038] The carbonization chamber 1 is also provided with a local material inlet 8 formed to open into the carbonization chamber 1, a local material inlet tube 7 attached so as to surround the periphery of the local material inlet 8, an opening / closing door 9 for releasably closing the outer opening surface of the local material inlet tube 7, a carbonized material outlet 10 for taking out carbonized local materials (hereinafter referred to as carbonized material) formed in the lower part of one side surface of the carbonization chamber 1, and an opening / closing door 11 for releasably closing the carbonized material outlet 10. The carbonization mechanism is further provided with a carbonization burner 14 for performing indirect heating as a primary combustion burner, a cooling blower 15, and a fireproof insulation material 16.

[0039] The communication passage 17 is composed of a gas riser pipe (inner pipe) 1a, an exhaust gas riser pipe 13a (outer pipe), a fireproof insulation material 12, and an air inlet hole 28. In addition to the secondary combustion chamber 18, the secondary combustion mechanism is composed of partition plates 18a, 18b, 18c, an opening 18d, a fireproof insulation material 19, an air passage portion 20, a sleeve 21, a secondary combustion burner 23, an injection hole 23a, a secondary combustion blower 24, an air outlet 25, an exhaust port 29, a cylindrical regulating portion 30, and an L-shaped regulating portion 31.

[0040] The carbonization chamber 1, which stores local materials, is formed as a covered cylinder that is laid on its side, and a triangular prism-shaped agitator 2 is provided inside so as to rotate freely. The agitator 2 rotates at a low speed to agitate and break down the local materials into small pieces while promoting the generation of gas, and its agitator shaft 3 is provided so as to protrude from one end face of the carbonization chamber 1. A gear 4 is provided on this agitator shaft 3, and it is linked to a motor 6 via a chain 5. Reference numeral 7 denotes a local material input tube provided in communication with the upper peripheral surface of the carbonization chamber 1, and a local material input port 8 of the local material input tube 7 is provided with an opening / closing door 9. Reference numeral 10 denotes a carbonized material outlet that opens into the bottom peripheral surface of the carbonization chamber 1, and this carbonized material outlet 10 is provided with an opening / closing door 11 so as to be able to open and close freely.

[0041] The indirect heating chamber 13 is provided so as to surround the outer periphery of the carbonization chamber 1. The indirect heating chamber 13 is formed in a cylindrical shape with a cover, eccentrically arranged with a wide gap at the bottom and a narrow gap at the top with respect to the carbonization chamber 1, and one end face is arranged flush with one end face of the carbonization chamber 1, and the carbonization chamber 1 is fixed in a suspended state at this end face. The other end face of the indirect heating chamber 13 is provided with a carbonization burner 14 located on the bottom side and burning toward the inside, and a cooling blower 15 that blows air inside. A fireproof insulation material 16 is provided over the entire inner wall of the indirect heating chamber 13.

[0042] The heating temperature of the carbonization chamber 1 is automatically controlled by controlling the heat of the carbonization burner 14 based on the detection by a temperature sensor (not shown) provided in the carbonization chamber 1. Also, although the carbonization chamber 1 and the indirect heating chamber 13 are shown as being formed in a cylindrical shape with a lid, they may be in the shape of a rectangular box, and their shapes are not limited.

[0043] A communication passage 17 is provided at the top of the coking chamber 1 and the indirect heating chamber 13, which communicates between the coking chamber 1 and the indirect heating chamber 13 and a secondary combustion chamber 18 described later. This communication passage 17 serves as an exhaust port for the coking chamber 1 and the indirect heating chamber 13, and is double-layered with a gas riser pipe (inner pipe) 1a that communicates with the upper peripheral surface of the coking chamber 1, and an exhaust gas riser pipe 13a (outer pipe) that is disposed around the gas riser pipe 1a and communicates with the indirect heating chamber 13. A fireproof heat insulating material 12 is provided inside the exhaust gas riser pipe 13a.

[0044] A secondary combustion chamber 18 is provided above the carbonization chamber 1 and the indirect heating chamber 13, communicating with each other through a communication passage 17. An air passage 20, which serves as a ventilation passage for air from a secondary combustion blower 24 described later, is provided on the outside of the deodorization chamber 18, and is formed into a box-shaped double structure as a whole. A fireproof insulation material 19 is laid on the inside of the air passage 20, i.e., on the entire inner wall of the secondary combustion chamber 18. A plurality of blowing holes 25 are formed through the fireproof insulation material 19 at appropriate intervals, and the blowing holes 25 are formed to be connected to the inner wall of the secondary combustion chamber 18, i.e., the air passage 20.

[0045] A cylindrical sleeve 21 made of a refractory material is provided at the entrance of the secondary combustion chamber 18, extending from the communication passage 17. The sleeve 21 is disposed slightly above the entrance of the secondary combustion chamber 18, with one end thereof contacting the injection hole 23a of the secondary combustion burner 23 and the other end disposed so that a space is provided between the sleeve 21 and the opening 18d of the partition plate 18a. Gas from the gas riser pipe (inner pipe) 1a and the exhaust gas riser pipe 13a (outer pipe) of the communication passage 17 comes into contact with the sleeve 21, which has become hot, through a gap formed between the sleeve 21 and the outlet of the communication passage 17, and becomes a hot, easily combustible gas.

[0046] Furthermore, this gas is combusted by the combustion gas injected into the sleeve 21 in the space provided between the other end of the sleeve 21 and the opening 18d of the partition plate 18a. The gas combusted in this space passes through the opening 18d of the partition plate 18a and is sent into the cylindrical regulating part 30 provided on the opposite side of the partition plate 18a from the sleeve 21. A turbulence generating part 30e is provided at the entrance of the cylindrical regulating part 30, and the hot air becomes a uniform turbulent state inside the cylindrical regulating part 30. This uniform turbulent hot air re-burns the unburned gas that was not completely burned in the space provided between the other end of the sleeve 21 and the opening 18d of the partition plate 18a, between the entrance of the cylindrical regulating part 30 and the exit of the cylindrical regulating part 30. This reburned gas is sent out from the outlet into the secondary combustion chamber 18 and, because of the L-shaped regulating section 31 at the top, returns along the outer side of the cylindrical regulating section 30 toward the partition plate 18a, and then rises along the partition plate 18a, passing over the top of the L-shaped regulating section 31 to reach the exhaust port 29, and is discharged to the outside.

[0047] A secondary combustion burner 23 that burns inward is provided on the side of the inlet of the secondary combustion chamber 18, along with a secondary combustion blower 24 that blows air into the air passage 20. The secondary combustion burner 23 and the secondary combustion blower 24 are designed to start in conjunction with each other. Although not shown, temperature sensors are provided at appropriate positions in the carbonization chamber 1 and the secondary combustion chamber 18, and the carbonization burner 14 and the secondary combustion burner 23 are controlled by temperature detection so that the temperature of the secondary combustion chamber 18 does not exceed a certain temperature.

[0048] Further, a plurality of air inlet holes 28 are formed obliquely upward from the outside to the inside near where the outer exhaust gas uprising pipe 13a constituting the communication passage 17 is connected to the secondary combustion chamber 18. These air inlet holes 28 communicate with the above-mentioned ventilation passage portion 20, and air is blown from the secondary combustion blower 24.

[0049] The carbonization chamber 1, the indirect heating chamber 13 and the secondary combustion chamber 18 are housed in a housing (not shown), and the secondary combustion chamber 18 is arranged horizontally in this housing, while the carbonization chamber 1 and the indirect heating chamber 13 are arranged with one end surface (the surface where the carbonized material outlet 8 is located) high and the other end surface (the surface where the carbonization burner 14 and the cooling blower 15 are located) inclined low. This makes it easier for the fire power of the carbonization burner 14 to heat the carbonization chamber 1 from the bottom side, and makes it easier for the indirect heating chamber 13 to rise to the exhaust gas riser pipe 13a as an exhaust pipe for the exhaust gas of the carbonization burner 14. Although the one end surface side of the indirect heating chamber 13 where the carbonized material outlet 8 is located is higher, the carbonized material can be easily removed by scraping it out.

[0050] The operation of the secondary combustion carbonization apparatus S12 configured as above will be described with reference to FIG. 4. That is, as shown in FIG. 4 as a process operation diagram, when an operation start switch (not shown) of the secondary combustion carbonization apparatus S12 is turned on (ON), the secondary combustion burner 23 is ignited first to start the temperature raising operation of the secondary combustion chamber 18. When it is confirmed that the temperature of the secondary combustion chamber 18 has risen to a set temperature, for example, 150°C, the carbonization burner 14 as a primary combustion burner is ignited to start the temperature raising operation of the indirect heating chamber 13. As the temperature of the indirect heating chamber 13 rises, the carbonization chamber 1 surrounded by it is indirectly heated from the outside. The ignition state of the carbonization burner 14 is controlled ON-OFF so that the temperature of the indirect heating chamber 13 is within a set range (for example, 250°C to 300°C).

[0051] As described above, as the temperature of the indirect heating chamber 13 rises, the carbonization chamber 1 is indirectly heated from the outside, and the temperature here also rises gradually, and as the temperature rises, the local materials put into the carbonization chamber 1 are dried as the moisture evaporates from the inside, reducing in volume and carbonizing into charcoal as the moisture content decreases. In particular, in this embodiment, the local materials put into the carbonization chamber 1 are never burned, but become charcoal as the moisture content decreases due to the evaporation of the moisture inside, and to this extent, the energy inherent in the local materials is retained even when they become charcoal, in other words, charcoal is produced with very high energy efficiency.

[0052] On the other hand, in the secondary combustion chamber 18, moisture from the local materials generated in the carbonization chamber 1 passes through the gas riser pipe (inner pipe) 1a of the communication passage 17, and exhaust gas and the like discharged from the carbonization burner 14 to the indirect heating chamber 13 passes through the exhaust gas riser pipe (outer pipe) 13a of the communication passage 17 and is brought to this secondary combustion chamber 18, and both are combusted by the combustion flame of the secondary combustion burner 23. At that time, as described above with reference to FIG. 4, the combustion flame from the secondary combustion burner 23 raises the temperature inside the secondary combustion chamber 18 to a temperature exceeding 800°C. In other words, high-temperature (approximately 800°C or higher) exhaust gas is discharged from the exhaust port 29 provided in the secondary combustion chamber 18. In this way, the secondary combustion burner 23 maintains a high temperature inside the secondary combustion chamber 18, and the moisture and exhaust gases evaporated from the local materials used as raw materials for charcoal are not only burned by exposure to the combustion flame from the secondary combustion burner 23, but are also more reliably eliminated by remaining in this high-temperature secondary combustion chamber 18 for a predetermined period of time.

[0053] On the other hand, an exhaust duct 40 is connected to the exhaust port 29 of the secondary combustion chamber 18, and is configured to guide and supply high-temperature (about 800°C or higher) exhaust gas discharged from the exhaust port 29 to a steam generator S14 described later. Here, the steam generator S14 will be described in detail later, but its function is a heat exchanger, in other words, it is configured to play the role of a gas / steam type steam generator (i.e., a boiler) that generates steam by the heat supplied thereto. In this way, a high temperature of 800°C or higher is obtained as heat from the secondary combustion chamber 18 that is used for heat exchange in the steam generator S14 as a heat exchanger, and it is possible to dramatically improve the power generation efficiency of the steam power generation device S16 connected to the steam generator S14 as a heat exchanger.

[0054] Furthermore, as is clear from the above configuration, the secondary combustion carbonization device S12 used in this embodiment is not a carbonization furnace, but rather a device that uses indirect heating to heat local materials at a relatively low temperature, evaporating the moisture inside and turning the materials into so-called "charcoal" when the moisture content has been sufficiently reduced, and therefore has a different configuration from conventional carbonization furnaces.

[0055] In addition, in this embodiment, the secondary combustion type charcoal making apparatus S12 is equipped with a housing (not shown) that houses the structures shown in Figures 1 and 2, and it goes without saying that the indirect heating chamber 13 and the secondary combustion chamber 18 are not exposed to the outside.

[0056] Next, with reference to FIG. 5, the configurations of the steam generator S14 and the steam power generation device S16 that generates power based on the steam generated by the steam generator S14 will be described, although only briefly.

[0057] First, the steam generator S14 receives high-temperature exhaust gas exceeding 800°C discharged from the exhaust port 29 of the secondary combustion carbonization apparatus S12 having the above-described configuration via the exhaust duct 40, and converts the heat of the received exhaust gas into high-temperature, high-pressure steam by heat exchange. It is a so-called gas-steam heat exchanger, and has a well-known structure known as a gas / steam boiler that uses high-temperature exhaust gas as a heat source.

[0058] The steam power generation unit S16 is configured to generate electricity by receiving high-temperature, high-pressure steam generated in the steam generation unit S14, and in this embodiment, it utilizes a product known as a small screw-type power generation unit manufactured by Kobe Steel, Ltd. under the trade name "Steam Star" (registered trademark) / model number: MSEG160L.

[0059] That is, as shown in Fig. 5, the steam power generation device S16 has a well-known structure as a screw-type small steam power generation device, and includes a screw-type expander 50 that receives high-temperature, high-pressure steam supplied from the steam generator S14 and rotates a drive shaft. A generator 52 is connected to the drive shaft, and generates electricity in response to the rotation of the drive shaft, outputting electricity having a predetermined voltage and current value. A control panel 56 is connected to the generator 52 via a converter 54, and electricity is supplied from the control panel 54 to the power storage station S18 via a power cord.

[0060] On the other hand, the output of the screw type expander 50 is connected to a condenser 58, and the steam after being used for power generation in the expander 50 is brought to the condenser 58 where it is converted into low-pressure water and converted into steam / liquid. This low-pressure water is then pressurized by a water supply pump 60 to become high-pressure water and is supplied to the steam generator S12 as the raw material for the high-temperature, high-pressure steam. In this way, the high-pressure water supplied from the water supply pump 60, using the high-temperature exhaust gas of 800°C generated in the secondary combustion type charcoal making device S12 as a heat source, is heat exchanged with the high-temperature exhaust gas to become high-temperature, high-pressure steam, which is supplied to the screw type small steam generator S16 and used for power generation.

[0061] 6, the power storage station S18 is provided with a plurality of detachable storage batteries 62, and each storage battery 62 is configured to be charged by receiving electricity supplied from the screw type small steam power generator S16. Thus, the power storage station S18 is provided with a plurality of, for example, 1,000 storage batteries 62, but in this embodiment, in order to improve the power storage efficiency, first, for example, 20 storage batteries 62 are classified into a plurality of, for example, 50 groups G1 to G50, and group distribution boards 64-1 to 64-50 are provided for supplying power to the storage batteries 62 classified in each group G1 to G50, and further, a main distribution board 66 is provided for individually distributing electricity supplied from the control board 56 of the screw type small steam power generator S16 via a power cable to the 50 group distribution boards 64-1 to 64-50. A control device 68 is connected to the main distribution board 66 and is configured to control to which of the group distribution boards 64-1 to 64-50 the electricity supplied from the control board 56 via the power cable is selectively distributed.

[0062] In this way, in this electricity storage station S18, the main distribution board 66 is controlled in accordance with the control procedures of the control device 68 so that electricity is distributed (supplied) in the order of the lowest numbered group distribution boards 64-1 to 64-50 of the group in which the uncharged storage batteries 62 are located, and even if the electrical output supplied from the screw-type small steam generator S16 is insufficient to fully charge 1,000 storage batteries 62 at once, it is possible to fully charge 20 storage batteries 62 in one charging operation, and by storing electricity in each of the 20 storage batteries 62 in sequence, it is possible to fully charge all 1,000 storage batteries 62, although it takes some time. Specifically, if we assume that it takes two days to fully charge 20 storage batteries 62, then it would take 100 days to fully charge 1,000 storage batteries 62 (in other words, it would only take 100 days). As a response to a disaster that may occur at any time, 100 days is not a particularly long period of time as a preparation period for initial charging, and we believe that this is a system that has ample industrial applicability.

[0063] In this embodiment, if the storage battery 62 that has already been fully charged is left alone, it will naturally discharge, albeit slightly, and will gradually lose power. Therefore, in this embodiment, while the storage battery 62 of a certain group is being charged with 20 batteries, a charging current is supplied to the storage battery 62 of the group that has already been fully charged to compensate for the discharged amount, so that the charging state of the storage battery 62 that has already been fully charged is always set to be fully charged.

[0064] Furthermore, the storage operation of the storage battery 62 in this storage station S18 is always running in a steady state when no emergency such as a disaster occurs. In this steady state, charcoal production using local materials is regularly carried out on a daily basis in the secondary combustion charcoal production apparatus S12, and the produced charcoal is sold as charcoal for BBQs, supplied to local farmers as a soil conditioner, or used in individual households as a water purification agent, thereby contributing to improving the local economy and quality of life, and thereby achieving a situation that contributes to the strengthening of the local area.

[0065] On the other hand, if a disaster occurs and the power supply from the local power company is stopped (i.e., a power outage occurs), the secondary combustion type charcoal making device S12 immediately stops making charcoal, and many inconveniences will occur due to the power outage at each home, store, business, etc. in the area. In such a disaster situation, the storage battery 62 that has completed storing electricity at the electricity storage station S18 will be removed from the connection terminal and distributed to each home, store, business, etc. in the area to be used for electricity consumption. In particular, the storage battery 62 is set to store electricity for three days at 1500W, which is expected to be the minimum daily electricity consumption in each home (for example, the minimum amount of electricity required for lighting and powering a refrigerator and a charging station) and the minimum amount of electricity required for lighting and PC operation in a business.

[0066] In addition, once the storage batteries 62 are distributed to each home, store, and business, used for power consumption, and the charge is depleted, if it is necessary to reuse them, they can be collected from the distribution destination and reattached to the power storage station S18 for recharging. In this way, by making the system rechargeable, if a disaster is serious and it takes two weeks for the power outage to be restored, as in the case of the Great East Japan Earthquake, the recharged storage batteries 62 can be redistributed to the region, making it possible to cover the minimum power consumption until the power is restored, thereby making it possible to strengthen the region.

[0067] It goes without saying that the present invention is not limited to the configuration of the embodiment described above, and various modifications are possible without departing from the gist of the present invention. [Industrial Applicability]

[0068] As described above, the community resilience system of the present invention comprises a storage station for accumulating and storing local materials such as thinned wood, bamboo, and pruned branches that are used for charcoal production; a secondary combustion type charcoal production device into which the local materials stored in the storage station are input and indirectly heated using a primary combustion burner to produce charcoal, and which burns gas generated during charcoal production using a secondary combustion burner, the secondary combustion type charcoal production device having an exhaust port for discharging exhaust gas after secondary combustion; a heat exchanger that generates high-pressure, high-temperature steam using the heat in the exhaust exhausted from the exhaust port of the charcoal production device; a power generation device that generates steam power using the steam generated by the heat exchanger; and steam generated by the power generation device. This system is characterized by having a storage station that is equipped with multiple batteries that store electricity and from which the batteries can be removed. Under normal circumstances, charcoal produced by the charcoal making equipment is supplied to the local area as charcoal for BBQs, a soil conditioner, a water purifier, etc., and at least in the event of a power outage in the local area during a disaster, the stored batteries in the storage station can be removed and distributed to homes, stores, and businesses in the surrounding area to be used as emergency power sources, and used batteries can be collected and recharged at the storage station. This can contribute to strengthening the local area in response to disasters and has high industrial applicability. [Explanation of symbols]
