Summary of the Invention

Problems to be Solved by the Invention

[0004] In the prior art, it is difficult to replace a functional unit arranged in a transport container with another unit and reorganize it into a container module having a function other than power generation.

[0005] The present invention has been made to solve this problem, and an object thereof is to provide a container module that can be easily reorganized into one having another function by replacing functional units.

Means for Solving the Problems

[0006] To achieve this object, the container module of the present invention includes a transport container and a plurality of functional units housed in the transport container. The functional units include a power supply unit, and the power supply unit includes a distribution board that divides power for each of the functional units.

Effects of the Invention

[0007] According to the first embodiment, the functional unit housed in the transport container includes a power supply unit, which includes a distribution board that distributes power to each of the functional units. Since the power supply unit can supply power to each of the functional units, the functional units can be easily swapped out to create a configuration with different functions.

[0008] According to the second embodiment, in the first embodiment, the distribution board includes a plurality of branch circuit breakers, two or more of which have the same rated breaking capacity. Since the rated breaking capacity is smaller than the largest power consumption of the functional units, the power required by the functional unit with the largest power consumption can be supplied from the plurality of branch circuit breakers. This eliminates the need to provide a dedicated branch circuit breaker and a dedicated wire with a large allowable current for the functional unit with the largest power consumption.

[0009] According to a third embodiment, in the second embodiment, the functional unit with the highest power consumption is connected to multiple branch circuit breakers. Since power can be supplied to the functional unit with the highest power consumption from multiple branch circuit breakers, the functional unit can be operated.

[0010] According to the fourth aspect, in the second or third aspect, all branch circuit breakers have the same rated breaking capacity. Since it is sufficient to connect wires with the same large allowable current to the branch circuit breakers, it is not necessary to prepare wires with different allowable currents.

[0011] According to the fifth aspect, in the first or second aspect, a relay connector connecting the distribution board and the functional unit is provided in the functional unit, which includes a power supply unit. The distribution board and the functional unit can be easily connected using the relay connector.

[0012] According to the sixth aspect, in the first or second aspect, one of the functional units includes an integrated control device that controls two or more functional units, and a concentrator to which LAN cables connected to two or more functional units are connected. The concentrator allows for easy connection between the integrated control device and the functional units, and the integrated control device can synchronize control instructions for multiple functional units and appropriately control multiple functional units.

[0013] According to the seventh aspect, in the sixth aspect, the power supply unit includes an integrated control device and a concentrator. The functions of distributing power and aligning control instructions can be integrated into the power supply unit. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0015] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Figure 1 is a perspective view of a container module 10 in one embodiment. The container module 10 comprises a transport container 11 and a plurality of functional units 17 housed in the transport container 11. In this embodiment, four functional units 17 are arranged in the transport container 11.

[0016] The transport container 11 is a large, rectangular container, primarily made of steel, used for cargo transport. Since the functional unit 17 is housed within the transport container 11, the container module 10 can be assembled at the factory, transported directly to the site, and installed there. This eliminates the need for large-scale construction work for on-site installation. Furthermore, the capacity of the equipment can be easily increased by stacking or arranging the container modules 10 side-by-side.

[0017] The transport container 11 comprises a rectangular base 12 in plan view, a rear wall 13 provided on the long side of the base 12, two side walls 14 provided on the short side of the base 12, a roof 15 connecting the rear wall 13 and the side walls 14, and a double-hinged front door 16 provided on the long side of the base 12 opposite the rear wall 13. Part of the front door 16 is omitted from the illustration. Normally, the container module 10 is operated with the front door 16 closed. In this embodiment, the rear wall 13 and side walls 14 consist of double-hinged doors. However, it is of course possible to make the rear wall 13 and side walls 14 into panels that cannot be opened or closed.

[0018] A functional unit 17 is a unit of equipment that performs a specific role. The container module 10 achieves a specific function through a combination of multiple functional units 17. The multiple functional units 17 are arranged from one side wall 14 of the transport container 11 to the other side wall 14. The functional units 17 are vertically elongated rectangular parallelepipeds of approximately the same size. In this embodiment, the functional unit 17 includes a power supply unit 18, an electrolysis unit 19, a recovery unit 20, and a generation unit 21. The functional units 17 are arranged in a single line horizontally across the transport container 11 in the order of power supply unit 18, electrolysis unit 19, recovery unit 20, and generation unit 21.

[0019] FIG. 2 is a block diagram of the container module 10. Hereinafter, as an example, the container module 10 that recovers carbon dioxide contained in the exhaust gas generated by the exhaust gas source 22 and reuses the carbon dioxide as a carbon compound to produce fuel will be described. The exhaust gas source 22 is not particularly limited as long as it generates exhaust gas containing carbon dioxide. Examples of the exhaust gas source 22 include power plants, factories, waste treatment facilities, natural gas fields, and oil fields.

[0020] The power supply unit 18 (see FIG. 1) included in the container module 10 distributes electric power to each device. The electrolysis unit 19 includes an electrolysis device that produces hydrogen and oxygen by electrolysis of water. The recovery unit 20 includes a removal device that removes moisture from the exhaust gas, a separation device that separates nitrogen oxides contained in the exhaust gas, and a recovery device that separates carbon dioxide contained in the exhaust gas and concentrates the carbon dioxide. The generation unit 21 includes a generation device that reduces carbon dioxide with hydrogen to generate fuel. The fuel is a combustible product, and examples thereof include methane, carbon monoxide, methanol, formaldehyde, and the like.

[0021] Examples of the method for removing moisture (water vapor) from the exhaust gas in the removal device of the recovery unit 20 include condensation, physical adsorption, and chemical reaction. As a method for removing nitrogen oxides from the exhaust gas in the separation device, a wet method using caustic soda or the like and a dry method for reducing nitrogen oxides to nitrogen using a denitration catalyst and a reducing agent are generally used. When the moisture in the exhaust gas is removed by the removal device or the nitrogen oxides are removed from the exhaust gas by the separation device, the concentration efficiency of carbon dioxide by the recovery device can be ensured.

[0022] The first mixed gas containing carbon dioxide separated and recovered from the exhaust gas in the recovery device is supplied to the generation unit 21 (generation device). In the generation device, for example, a catalyst is used to lower the activation energy and advance the chemical reaction from carbon dioxide to fuel.

[0023] The first mixed gas may contain impurities other than carbon dioxide in an amount of 10 vol% or more. A lower amount of impurities in the first mixed gas is preferable because it increases the purity of the fuel contained in the second mixed gas discharged by the generating device. However, this would complicate the device for separating impurities from the first mixed gas. Therefore, from the standpoint of simplifying the container module 10, a certain degree of impurity inclusion is permissible.

[0024] In the electrolysis unit 19 (electrolytic device), examples of methods for electrolyzing water include alkaline water electrolysis, solid polymer electrolyte water electrolysis, and high-temperature steam electrolysis using a solid oxide electrolytic cell (SOEC). High-temperature steam electrolysis is preferred because it can produce a large amount of hydrogen with less power compared to alkaline water electrolysis and solid polymer electrolyte water electrolysis. It is preferable that the electrolysis device performs high-temperature steam electrolysis using an SOEC, and that the heat of chemical reaction generated in the generation device is used to generate the steam, as this improves the energy efficiency of the container module 10.

[0025] The second mixed gas discharged by the generating device may contain hydrogen and components of the first mixed gas in addition to the fuel, but the amount of gas other than fuel in the second mixed gas is preferably 45 vol% or less of the amount of the second mixed gas.

[0026] It is preferable to have the second mixed gas generated by the container module 10 used by facilities on the site, including the exhaust gas source 22, as this reduces the cost of transporting the gas. By simplifying the container module 10, it can be made smaller, thus reducing the space required for its installation. Since a container module 10 can be installed for each exhaust gas source 22, the carbon dioxide emitted by each exhaust gas source 22 can be reused as a carbon resource for each exhaust gas source 22. With the container module 10, carbon dioxide emissions can be reduced while producing fuel of the minimum necessary quality that can be used by facilities on the site, including the exhaust gas source 22, rather than producing fuel intended for sale.

[0027] Figure 3 is a perspective view of the base 12 of the transport container 11. Figure 3 shows the floor plate 25a with a portion removed by a break line. Here, the side with the front door 16 is referred to as the front, and the side with the rear wall 13 is referred to as the rear.

[0028] The transport container 11 has multiple platforms 23 extending in the front-to-back direction and intersecting the rear wall 13, which are provided on the base 12 at predetermined intervals in the lateral direction. Multiple connecting parts 24 connecting the platforms 23 are provided at predetermined intervals in the front-to-back direction. The platforms 23 and connecting parts 24, which are arranged in a grid pattern, are supported by multiple legs 25 scattered on the base 12. A floor plate 25a is placed on the connecting parts 24. The platforms 23 are positioned higher than the floor plate 25a. One functional unit 17 is placed on one set of platforms 23.

[0029] Multiple rollers 26 are arranged on the part of the base 23 that the functional unit 17 contacts, causing the functional unit 17 to rub against them and rotate in the front-to-back direction. The rollers 26 are scattered along the entire length of the base 23 in the front-to-back direction. Examples of rollers 26 include balls and rollers. The rollers 26 move up and down relative to the base 23 by a lifting mechanism (not shown) located beneath the rollers 26. An example of a lifting mechanism is an elastic tube that contains a fluid such as air or oil. The tube is positioned along the base 23 beneath the rollers 26.

[0030] When fluid is supplied to the elevator tube, the tube expands and the roller 26 rises. After transporting the functional unit 17 and placing it on the platform 23, pushing the functional unit 17 backward (in the first direction) causes the functional unit 17 to rub and the roller 26 to rotate. Therefore, the functional unit 17 can be moved along the platform 23 in the first direction with little force.

[0031] A stopper 27 is interposed between the rear end of the base 23 and the rear wall 13. Examples of materials for the stopper 27 include rubber and synthetic resin. In this embodiment, the stopper 27 is attached to the rear wall 13. One stopper 27 is located behind two adjacent bases 23. When a functional unit 17 moving in the first direction reaches the position of the stopper 27, it hits the stopper 27 and its movement is restricted. The stopper 27 cushions the impact when the functional unit 17 hits it. Since one stopper 27 restricts the movement of two adjacent functional units 17, the number of stoppers can be reduced compared to the case where a stopper is provided for each functional unit 17.

[0032] A support section 28 is provided between two adjacent bases 23. The support section 28 is a member that extends front to back along the base 23 and is supported by the legs 25. A guide 29 is provided on the support section 28. The guide 29 includes a plurality of shafts 30 extending upward from the support section 28 and rollers 31 provided on the shafts 30. When viewing the support section 28 from above, the shape formed by connecting the shafts 30 in order from front to back is a zigzag. The rollers 31 are positioned higher than the rollers 26. The guide 29 restricts the lateral movement of the functional unit 17 when the rollers 26 rotate and the functional unit 17 moves back to back. The guide 29 allows for lateral positioning of the functional unit 17.

[0033] As the roller 26 rotates and the functional unit 17 moves, the roller 31 rubs against the functional unit 17, causing it to rotate around the shaft 30. The roller 31 acts as a friction reducing part, reducing the frictional force between the guide 29 and the functional unit 17, thus making it easier to move the functional unit 17 back and forth along the guide 29.

[0034] After moving the functional unit 17 in the first direction (rearward), the fluid clogged in the elevator tube is released, causing the tube to contract and the roller 26 to descend. As a result, the functional unit 17 comes into contact with the base 23, and the frictional force between the functional unit 17 and the base 23 fixes the functional unit 17 to the base 23. After placing the functional unit 17 on the base 23, fasteners (not shown) may be attached to one or more of the base 23, floor plate 25a, and support part 28 to mechanically fix the functional unit 17 and prevent it from moving in the second direction (forward).

[0035] When removing the functional unit 17, which is fixed to the base 23, from the transport container 11, fluid is supplied to the elevator tube to inflate the tube and raise the rollers 26. As the functional unit 17 rubs against the rollers 26, the rollers 26 rotate, allowing the functional unit 17 to move forward (in a second direction) along the base 23. This allows the functional unit 17 to be removed from the base 23.

[0036] The width W (see Figure 1) of all functional units 17 in the direction in which they are lined up (horizontal direction) is the same for all functional units 17. The distance between the bases 23 on which the functional units 17 are placed is also the same for all of them. Since the horizontal dimensions of the functional units 17 and bases 23 are standardized, any functional unit 17 can be placed on any base 23. Therefore, the freely combined functional units 17 can be placed at any position within the transport container 11.

[0037] The height T (see Figure 1) of all functional units 17 is greater than the width W of each functional unit 17. This allows for a reduction in the width of the base 12 of the transport container 11 on which multiple functional units 17 are arranged, while still maintaining the volume of the functional units 17. Consequently, the site required for installing the container module 10 can be reduced. Multiple electrical wires 32 (see Figure 4) and LAN cables 33 (see Figure 5) are arranged between the base 12 and the platform 23.

[0038] Figure 4 is a block diagram of the power supply system of the container module 10. In Figure 4, for convenience, the power supply unit 18 is shown with different dimensions from the other functional units 17, but as mentioned above, the functional units 17, including the power supply unit 18, are all vertically elongated rectangular prisms of approximately the same size (the same applies in Figure 5).

[0039] The power supply unit 18 includes a main circuit breaker 34 and a distribution board 35 on which multiple (five in this embodiment) branch circuit breakers 36 are arranged. The capacity of the main circuit breaker 34 is determined according to the electrical capacity of the devices used in the container module 10. The main circuit breaker 34 detects the current and shuts off the circuit when the total power consumption in the container module 10 exceeds the rated breaking capacity of the main circuit breaker 34. A main earth leakage circuit breaker may also be provided in the distribution board 35.

[0040] Branch circuit breakers 36 are provided for each branch circuit separated from the main circuit breaker 34. Relay connectors 37 connected to each branch circuit breaker 36 are located on the power supply unit 18. Functional units 17 other than the power supply unit 18 (in this embodiment, the electrolysis unit 19, the recovery unit 20, and the generation unit 21) are connected to the relay connectors 37. As a result, the power supply unit 18 distributes the power supplied to the main circuit breaker 34 to the functional units 17 other than the power supply unit 18. The branch circuit breakers 36 detect the current and interrupt the circuit if the power consumption of the functional units 17 connected to the relay connectors 37 exceeds the rated breaking capacity of the branch circuit breaker 36. Branch-type earth leakage circuit breakers may also be provided in the distribution board 35.

[0041] The functional units 17, excluding the power supply unit 18, are each equipped with circuit breakers 38, 40, and 42. Circuit breaker 38 is the circuit breaker for the electrolysis unit 19, circuit breaker 40 is the circuit breaker for the recovery unit 20, and circuit breaker 42 is the circuit breaker for the generation unit 21. Circuit breakers 38, 40, and 42 each detect current and interrupt the circuit in the event of an overload or ground fault. Multiple circuit breakers 38 (three in this embodiment) are provided in the electrolysis unit 19. Relay connectors 39 connected to each circuit breaker 38 are provided in the electrolysis unit 19. One circuit breaker 40 and 42 are provided in the recovery unit 20 and one in the generation unit 21. Relay connectors 41 and 43 connected to circuit breakers 40 and 42 are provided in the recovery unit 20 and the generation unit 21, respectively.

[0042] The power supply unit 18 housed in the transport container 11 includes a distribution board 35 that distributes power to each of the functional units 17 other than the power supply unit 18. Since the power supply unit 18 can supply power to each of the functional units 17, the container module 10 can be easily rearranged to have different functions by swapping out the functional units 17.

[0043] Intermediate connectors 37, 39, 41, and 43 are connected to connectors provided on the electrical wires 32 located in the transport container 11 (see Figure 1). The connectors are visible, for example, on the floorboard 25a (see Figure 3). Electrical connection and disconnection between the functional units 17 can be easily performed by plugging and unplugging the connectors. Therefore, the amount of work required to complete the electrical connection of the container module 10 by placing the functional units 17 in the transport container 11 can be reduced.

[0044] Two or more of the multiple branch breakers 36 have the same rated breaking capacity C. By making the rated breaking capacity C of two or more branch breakers 36 the same, the number of types of branch breakers 36 can be reduced compared to when branch breakers with all different rated breaking capacities are installed in the distribution board 35. Furthermore, since wires with the same allowable current can be connected to branch breakers 36 with the same rated breaking capacity C, the number of types of wires connected to the branch breakers 36 can also be reduced. Since the number of types of branch breakers 36 and wires used in the container module 10 can be reduced, the costs required for their preparation and management can be reduced.

[0045] The rated breaking capacity C is set to a value smaller than the largest power consumption among the multiple functional units 17 connected to the distribution board 35. In this embodiment, among the electrolytic unit 19, recovery unit 20, and generation unit 21 connected to the distribution board 35, the electrolytic unit 19 has the largest power consumption, so the rated breaking capacity C is smaller than the power consumption of the electrolytic unit 19. On the other hand, the rated breaking capacity C is larger than the power consumption of the recovery unit 20 and generation unit 21. Also, the largest rated breaking capacity among the branch breakers 36 is smaller than the power consumption of the electrolytic unit 19, and the smallest rated breaking capacity among the branch breakers 36 is larger than the power consumption of the recovery unit 20 and generation unit 21.

[0046] The number of branch circuit breakers 36 is greater than the number of functional units 17 connected to the distribution board 35 (three in this embodiment). This allows multiple branch circuit breakers 36 to be connected to one functional unit 17, and branch circuit breakers 36 to be connected to the remaining functional units 17. As a result, by connecting multiple branch circuit breakers 36 to the breaker 38 located on the electrolysis unit 19, which has the highest power consumption, the electrolysis unit 19 can be supplied with the power it requires. Furthermore, the recovery unit 20 and the generation unit 21 can also be supplied with the necessary power. Therefore, the electrical connection when the functional units 17 are placed in the transport container 11 can be simplified.

[0047] In this embodiment, all branch breakers 36 have the same rated breaking capacity C. This allows for a single type of branch breaker 36. Furthermore, since all branch breakers 36 can be connected to wires with the same allowable current, the type of wire connected to the branch breakers 36 can be limited to one. Because only one type of branch breaker 36 and wire can be used in the container module 10, the costs required for their preparation and management can be reduced.

[0048] In this embodiment, all branch breakers 36 and breakers 38, 40, and 42 have the same rated breaking capacity C. This allows for a single type of branch breaker 36 and breakers 38, 40, and 42. Furthermore, since all branch breakers 36 and breakers 38, 40, and 42 can be connected to wires with the same allowable current, the type of wire connected to branch breakers 36 and breakers 38, 40, and 42 can be a single type. Because the container module 10 can use only one type each of branch breakers 36, breakers 38, 40, and 42, the costs required for their preparation and management can be further reduced.

[0049] Figure 5 is a block diagram of the signaling system of the container module 10. One of the functional units 17 includes an integrated control device 44 that controls two or more functional units 17, a concentrator 45 that has the function of connecting to a wide area network (WAN) such as the Internet, and a concentrator 47 that has the function of connecting to a local area network (LAN). The concentrator 45 has a WAN port 46. The concentrator 47 has multiple LAN ports 48. The integrated control device 44 controls the multiple functional units 17 connected to the concentrator 47 via the LAN ports 48. In this embodiment, the integrated control device 44 and the concentrators 45 and 47 are arranged in the power supply unit 18.

[0050] The functional units 17, excluding the power supply unit 18, are each equipped with concentrators 49, 51, and 53. The concentrators 49, 51, and 53 are devices that connect multiple lines and enable them to communicate with each other. LAN ports 50, 52, and 54, connected to the concentrators 49, 51, and 53, are respectively located in the electrolysis unit 19, the recovery unit 20, and the generation unit 21.

[0051] LAN ports 48, 50, 52, and 54 are connected to connectors provided on LAN cables 33 located in the transport container 11 (see Figure 1). The connectors are visible, for example, on the floorboard 25a (see Figure 3). The transmission paths between the functional units 17 can be easily connected and disconnected by plugging and unplugging the connectors. Therefore, the amount of work required when placing the functional units 17 in the transport container 11 and completing the transmission paths of the container module 10 can be reduced.

[0052] One of the functional units 17 includes an integrated control device 44 and a concentrator 47. The concentrator 47 allows for easy connection between the integrated control device 44 and other functional units 17, and the integrated control device 44 can synchronize control instructions for multiple functional units 17, thereby enabling appropriate control of multiple functional units 17. In this embodiment, the power supply unit 18 includes the integrated control device 44 and the concentrator 47. Therefore, the functions of distributing power and synchronizing control instructions can be integrated into the power supply unit 18.

[0053] Although the present invention has been described above based on embodiments, it can be easily inferred that the present invention is not limited in any way to the above embodiments, and that various improvements and modifications are possible without departing from the spirit of the present invention.

[0054] In this embodiment, a container module 10 has been described that includes a functional unit 17 consisting of an electrolysis unit 19, a recovery unit 20, and a generation unit 21, in addition to the power supply unit 18, but it is not necessarily limited to this. It is certainly possible to arrange various functional units 17 according to the role that the container module 10 plays, and to create a container module 10 that plays other roles. Examples of other container modules 10 include a module that produces hydrogen and oxygen from water as a raw material, a module that purifies carbon dioxide from exhaust gas, and a module that produces intermediates such as synthesis gas, methanol, and ethanol from carbon dioxide and hydrogen, and produces fuels such as diesel oil and gasoline, BTX, DME, butadiene, and chemical products from the intermediates.

[0055] In this embodiment, the case where the electrolysis unit 19 has the highest power consumption among the electrolysis unit 19, the recovery unit 20, and the generation unit 21 has been described, but it is not necessarily limited to this case. The power consumption of each functional unit 17 can be compared, and the functional unit 17 with the highest power consumption should be equipped with more circuit breakers than the other functional units 17.

[0056] In this embodiment, we have described a case in which four functional units 17 are mounted on a transport container 11 that has a platform 23 capable of mounting up to four functional units 17, but this is not necessarily the only case. The number of functional units 17 mounted on the transport container 11 is set appropriately according to the purpose of the container module 10. The transport container 11 may have a platform 23 capable of mounting five or more functional units 17, or there may be empty spaces on the platform 23 of the transport container 11.

[0057] In this embodiment, a case has been described in which rollers 31 are provided on a guide 29 located between the functional units 17, but the invention is not necessarily limited to this. It is naturally possible to replace the guide 29 with rollers 31 with a rail extending in the front-rear direction. In this case as well, the guide consisting of rails can be used to restrict the left-right position of the functional units 17 placed on the base 23.

[0058] Furthermore, it is certainly possible to provide at least a portion of the side surface of the rail (guide) with a friction-reducing section made of a material that has a low coefficient of friction with the functional unit 17 and excellent sliding properties. Examples of materials with excellent sliding properties include fluororesin, ultra-high molecular weight polyethylene, and polyacetal resin. In this case as well, the friction-reducing section makes it easier to move the functional unit 17 back and forth along the guide. The rail may also be made of a material with excellent sliding properties.

[0059] In the embodiment, the case where all functional units 17 have the same height T has been described, but it is not necessarily limited to this. There may be variations in the height T of the functional units 17. Preferably, the height T of the functional units 17 is greater than the width W.

[0060] In this embodiment, the case in which the concentrator 45 is equipped with a WAN port 46 and is connected to a wide-area communication network via a wired connection has been described, but it is not necessarily limited to this. It is of course possible to connect the wide-area communication network and the concentrator 45 wirelessly.

[0061] In the embodiment, the case in which a floor plate 25a is placed on the base 12 has been described, but the floor plate 25a can be omitted. This is because when the functional unit 17 is placed on the stand 23, the gap between the stand 21 and the stand 21 is closed by the functional unit 17, even without the floor plate 25a.
