[0014] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. However, the present disclosure can be implemented in many different forms, and should not be interpreted as being limited to the description of the embodiments exemplified below. In addition, in order to make the explanation clearer, the drawings may be schematic in terms of the width, thickness, shape, etc. of each part compared to the actual form, but these are merely examples and do not limit the interpretation of the present disclosure. In addition, in this specification and each figure, elements similar to those described above with respect to the previous figures may be given the same reference numerals, and detailed explanations may be omitted as appropriate.

[0015] (Hydrogen gas and tap water mixed transport system) The hydrogen gas / tap water mixed delivery system of the present disclosure will be described below. The hydrogen gas / tap water mixed delivery system of the present disclosure utilizes the fact that hydrogen gas is not easily dissolved in water and that the specific gravity of hydrogen gas is much lighter than the specific gravity of water. Fig. 1 is a diagram showing a configuration example of a hydrogen gas / tap water mixed delivery system of the present disclosure. Fig. 2 is a diagram showing a configuration example of a hydrogen gas / tap water mixer of the present disclosure. Fig. 3 is a diagram showing a configuration example of a hydrogen gas / tap water separator of the present disclosure.

[0016] First, the overall configuration of a hydrogen gas / tap water mixed delivery system 1 shown in FIG. 1 will be described. As shown in FIG. 1, the hydrogen gas / tap water mixed delivery system 1 includes, as its main components, a hydrogen gas / tap water mixer 10, a hydrogen gas / tap water mixed delivery pipe 40, and a hydrogen gas / tap water separator 50. The hydrogen gas / tap water mixed delivery pipe 40 acts as a pipe that mixes hydrogen gas and tap water and delivers them from the hydrogen gas / tap water mixer 10 to the hydrogen gas / tap water separator 50. The hydrogen gas / tap water mixer 10 is connected to the hydrogen gas / tap water mixed delivery pipe 40 and delivers the hydrogen gas and tap water to the hydrogen gas / tap water mixed delivery pipe 40. The hydrogen gas / tap water separator 50 is connected to the hydrogen gas / tap water mixed delivery pipe 40 and separates the hydrogen gas and tap water that have been mixed and delivered from the hydrogen gas / tap water mixer 10 via the hydrogen gas / tap water mixed delivery pipe 40.

[0017] 1 also includes a hydrogen gas pressure regulator 22. This hydrogen gas pressure regulator 22 sends hydrogen gas to the hydrogen gas / tap water mixer 10 via a hydrogen gas feed pipe 23 connected to the hydrogen gas / tap water mixer 10. A hydrogen gas tank 20 that sends hydrogen gas to the hydrogen gas pressure regulator 22 is connected to the hydrogen gas pressure regulator 22 via a hydrogen gas pipe 21.

[0018] In addition, a tap water supply pipe 30 that supplies tap water to the hydrogen gas and tap water mixer 10 is connected to the hydrogen gas and tap water mixer 10.

[0019] In addition, the hydrogen gas tap water mixer 10 has a water level sensor signal transmitter 110, and the hydrogen gas pressure regulator 22 has a water level sensor signal receiver 120 that receives a signal transmitted from the water level sensor signal transmitter 110. Here, the water level sensor signal transmitter 110 transmits a signal from the water level sensor 11 provided inside the hydrogen gas tap water mixer 10. Details of the water level sensor 11 and the water level sensor signal transmitter 110 will be described in detail later with reference to FIG.

[0020] On the other hand, the hydrogen gas tap water separator 50 has a hydrogen gas delivery pipe 51 that separates the hydrogen gas that has been mixed and sent to the hydrogen gas tap water separator 50 via the hydrogen gas / tap water mixed delivery pipe 40 from the tap water and sends it out, and a tap water delivery pipe 52 that separates the tap water that has been mixed and sent to the hydrogen gas tap water separator 50 via the hydrogen gas / tap water mixed delivery pipe 40 from the hydrogen gas and sends it out.

[0021] In the hydrogen gas and tap water mixed delivery system 1, hydrogen gas and tap water can be mixed and delivered through a single pipe (hydrogen gas and tap water mixed pipe 40), so there is no need to install a separate pipe for hydrogen gas in addition to the tap water pipe.

[0022] In addition, by generating electricity using a fuel cell system from the delivered hydrogen gas, equipment such as power transmission lines (electric wires) and power generation systems will no longer be necessary.

[0023] In other words, the hydrogen gas / tap water mixed delivery system of the present disclosure makes it possible to supply energy while reducing equipment costs.

[0024] Hereinafter, each component of the hydrogen gas / tap water mixed delivery system 1 will be described.

[0025] (Hydrogen gas / tap water mixer) First, the hydrogen gas / tap water mixer 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the hydrogen gas / tap water mixer of the present disclosure. More specifically, Fig. 2 is a diagram showing each component of the hydrogen gas / tap water mixer 10 and the internal state of the hydrogen gas / tap water mixer 10. Inside the hydrogen gas / tap water mixer 10 shown in FIG. 2, the side above the tap water surface (WH) (the side opposite to the direction of gravity, the Z direction in the figure) is filled with hydrogen gas, and the side below the tap water surface (WH) (the side in the same direction as the direction of gravity, the side opposite to the Z direction in the figure) is filled with tap water.

[0026] The hydrogen gas and tap water mixer 10 is connected to the hydrogen gas and tap water mixed transport pipe 40, and sends a mixture of hydrogen gas and tap water to the hydrogen gas and tap water mixed transport pipe 40. The hydrogen gas and tap water mixer 10 can send a mixture of hydrogen gas and tap water by taking advantage of the fact that hydrogen gas is not easily dissolved in water and that the specific gravity of hydrogen gas is much lighter than that of water.

[0027] As shown in FIG. 2, the hydrogen gas / tap water mixer 10 is connected to a hydrogen gas feed pipe 23, a tap water feed pipe 30, and a hydrogen gas / tap water mixed feed pipe 40.

[0028] 2, the hydrogen gas / tap water mixer 10 has a hydrogen gas / tap water mixing pipe 40 connected to the center of the side of the hydrogen gas / tap water mixer 10. However, the hydrogen gas / tap water mixing system of the present disclosure is not limited to this, and the hydrogen gas / tap water mixing pipe 40 may be provided between the upper surface (top surface) and the lower surface (bottom surface) of the hydrogen gas / tap water mixer 10.

[0029] Here, in the hydrogen gas / tap water mixed delivery system 1, the water level (WH) of the tap water inside the hydrogen gas / tap water mixed delivery pipe 40 is controlled to be between the upper end (KH) and the lower end (KL) of the inner diameter of the hydrogen gas / tap water mixed delivery pipe 40. The mechanism of this control will be described below.

[0030] 2, the hydrogen gas tap water mixer 10 has therein a water level sensor 11 that measures the level of tap water sent from the tap water supply pipe 30. The water level sensor 11 is connected to a water level sensor signal transmitter 110.

[0031] This water level sensor 11 measures the water level inside the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water mixer 10, and information on the measured water level is transmitted from the water level sensor signal transmitter 110 to the water level sensor signal receiver 120 provided in the hydrogen gas pressure regulator 22 shown in Figure 1. The hydrogen gas pressure regulator 22 shown in FIG. 1 adjusts the pressure of the hydrogen gas sent to the hydrogen gas / tap water mixer 10 via the hydrogen gas feed pipe 23 based on the information transmitted to the water level sensor signal receiver 120.

[0032] In this way, inside the hydrogen gas / tap water mixed pipe 40 connected to the hydrogen gas / tap water mixer 10, the tap water level (WH) is controlled to be between the upper end (KH) and the lower end (KL) of the inner diameter of the hydrogen gas / tap water mixed pipe 40.

[0033] In addition, in the hydrogen gas / tap water mixer 10 shown in FIG. 2, a hydrogen gas supply pipe 23 is connected to the upper side of the hydrogen gas / tap water mixer 10, thereby preventing the tap water mixed inside the hydrogen gas / tap water mixer 10 from mixing (flowing back) into the hydrogen gas supply pipe 23.

[0034] 2, the hydrogen gas supply pipe 23 is preferably provided on the upper surface (top surface) of the hydrogen gas / tap water mixer 10. If the hydrogen gas supply pipe 23 is connected to the upper surface (top surface) of the hydrogen gas / tap water mixer 10, it will be more reliably located above the tap water level (WH), and tap water can be prevented from mixing (backflowing) into the hydrogen gas supply pipe 23.

[0035] In order to prevent such mixing (backflow) of tap water, it is sufficient that the tap water surface (WH) is located below the hydrogen gas feed pipe 23 in the hydrogen gas / tap water mixer 10.

[0036] For example, when connecting the hydrogen gas supply pipe 23 to the side of the hydrogen gas and tap water mixer 10, in order to install the hydrogen gas supply pipe 23 so that the tap water level (WH) is below the hydrogen gas supply pipe 23, it is sufficient to design the hydrogen gas supply pipe 23 so that the upper end (KH) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water mixer 10 is located below the lower end of the inner diameter of the hydrogen gas supply pipe 23. This is because the tap water level (WH) is between the upper end (KH) and lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water mixer 10.

[0037] In addition, in the hydrogen gas / tap water mixer 10 shown in FIG. 2, by connecting a tap water supply pipe 30 to the lower side of the hydrogen gas / tap water mixer 10, the hydrogen gas mixed inside the hydrogen gas / tap water mixer 10 is prevented from mixing (backflowing) into the tap water supply pipe 30.

[0038] In order to prevent such mixing (backflow) of hydrogen gas, it is sufficient that the tap water level (WH) is located above the tap water feed pipe 30 in the hydrogen gas / tap water mixer 10.

[0039] 2, when connecting the hydrogen gas supply pipe 23 to the side of the hydrogen gas and tap water mixer 10, in order to install the tap water supply pipe 30 so that the tap water level (WH) is above the tap water supply pipe 30, it is necessary to design the hydrogen gas and tap water mixer 10 so that the lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water mixer 10 is located above the upper end of the inner diameter of the tap water supply pipe 30. This is because the tap water level (WH) is between the upper end (KH) and lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water mixer 10.

[0040] In the example shown in FIG. 2, in the hydrogen gas and tap water mixer 10, the tap water supply pipe 30 is provided on the underside of the side opposite to the side to which the hydrogen gas and tap water mixed supply pipe 40 is connected, but this is not limited thereto, and the tap water supply pipe 30 may be provided on another side as long as it satisfies the relationship with the tap water surface (WH) described above.

[0041] The tap water supply pipe 30 may be provided on the lower surface (bottom surface) of the hydrogen gas / tap water mixer 10. If the tap water supply pipe 30 is connected to the lower surface (bottom surface) of the hydrogen gas / tap water mixer 10, it will be more reliably located below the tap water surface (WH), and hydrogen gas can be prevented from mixing (backflowing) into the tap water supply pipe 30.

[0042] (Hydrogen gas tap water separator) Next, the hydrogen gas tap water separator 50 will be described with reference to Fig. 3. Fig. 3 is a diagram showing a configuration example of the hydrogen gas tap water separator of the present disclosure. More specifically, Fig. 3 is a diagram explaining each configuration related to the hydrogen gas tap water separator 50 and the internal state of the hydrogen gas tap water separator 50. Inside the hydrogen gas tap water separator 50 shown in FIG. 3, the side above the tap water surface (WH) (the side opposite to the direction of gravity, the Z direction in the figure) is filled with hydrogen gas, and the side below the tap water surface (WH) (the side in the same direction as the direction of gravity, the side opposite to the Z direction in the figure) is filled with tap water.

[0043] The hydrogen gas and tap water separator 50 is connected to the hydrogen gas and tap water mixed pipe 40, and separates the hydrogen gas and tap water that are mixed and sent from the hydrogen gas and tap water mixer 10 via the hydrogen gas and tap water mixed pipe 40. The hydrogen gas and tap water separator 50 can separate the hydrogen gas and tap water by taking advantage of the fact that hydrogen gas is not easily dissolved in water and that the specific gravity of hydrogen gas is much lighter than that of water.

[0044] As shown in FIG. 3, the hydrogen gas / tap water separator 50 is connected to a hydrogen gas delivery pipe 51 for delivering hydrogen gas and a tap water delivery pipe 52 for delivering tap water.

[0045] Here, because hydrogen gas does not easily dissolve in water and the specific gravity of hydrogen gas is much lighter than that of water, there is a tap water surface (WH) that serves as the boundary between hydrogen gas and tap water inside the hydrogen gas tap water separator 50. Inside the hydrogen gas tap water separator 50, the area above the tap water surface (WH) in the direction of gravity is filled with hydrogen gas, and the area below the tap water surface (WH) in the direction of gravity is filled with tap water.

[0046] Therefore, as shown in FIG. 3, in the hydrogen gas / tap water separator 50, by installing the hydrogen gas delivery pipe 51 so that the water level (WH) of the tap water is below the hydrogen gas delivery pipe 51, the hydrogen gas separated from the tap water can be delivered through this hydrogen gas delivery pipe 51.

[0047] Furthermore, as shown in FIG. 3, in the hydrogen gas tap water separator 50, by installing the tap water delivery pipe 52 so that the tap water level (WH) is above the tap water delivery pipe 52, the tap water separated from the hydrogen gas can be delivered through this tap water delivery pipe 52.

[0048] 3, when the hydrogen gas delivery pipe 51 is connected to the side of the hydrogen gas and tap water separator 50, in order to install the hydrogen gas delivery pipe 51 so that the tap water level (WH) is below the hydrogen gas delivery pipe 51, the hydrogen gas delivery pipe 51 may be designed so that the upper end (KH) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water separator 50 is located below the lower end of the inner diameter of the hydrogen gas delivery pipe 51. This is because the tap water level (WH) is between the upper end (KH) and the lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water separator 50.

[0049] In the example shown in Figure 3, in the hydrogen gas / tap water separator 50, the hydrogen gas delivery pipe 51 is provided on the upper side of the side opposite to the side to which the hydrogen gas / tap water mixed delivery pipe 40 is connected, but this is not limited to the above, and the hydrogen gas delivery pipe 51 may be provided on another side as long as it satisfies the relationship with the water surface (WH) of the tap water described above.

[0050] Furthermore, the hydrogen gas delivery pipe 51 may be provided on the upper surface (top surface) of the hydrogen gas / tap water separator 50. If the hydrogen gas delivery pipe 51 is connected to the upper surface (top surface) of the hydrogen gas / tap water separator 50, it will be more reliably located above the tap water level (WH), and the separated hydrogen gas can be delivered from the hydrogen gas delivery pipe 51 while more reliably preventing contamination by tap water.

[0051] Similarly, when connecting the tap water delivery pipe 52 to the side of the hydrogen gas and tap water separator 50, in order to install the tap water delivery pipe 52 so that the tap water level (WH) is above the tap water delivery pipe 52, it is sufficient to design the tap water delivery pipe 52 so that the lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water separator 50 is located above the upper end of the inner diameter of the tap water delivery pipe 52. This is because the tap water level (WH) is between the upper end (KH) and lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water separator 50.

[0052] In the example shown in Figure 3, in the hydrogen gas and tap water separator 50, the tap water delivery pipe 52 is provided on the underside of the side opposite to the side to which the hydrogen gas and tap water mixed delivery pipe 40 is connected, but this is not limited to this, and the tap water delivery pipe 52 may be provided on another side as long as it satisfies the relationship with the tap water level (WH) described above.

[0053] Furthermore, the tap water delivery pipe 52 may be provided on the lower surface (bottom surface) of the hydrogen gas tap water separator 50. If the tap water delivery pipe 52 is connected to the lower surface (bottom surface) of the hydrogen gas tap water separator 50, it will be more reliably located below the tap water level (WH), and hydrogen gas can be more reliably prevented from being mixed into the tap water delivery pipe 52 (backflow).

[0054] (Hydrogen gas and tap water mixed pipe) Next, the hydrogen gas / tap water mixed pipe of the present disclosure will be described. As shown in FIG. 1, the hydrogen gas / tap water mixed pipe 40 is provided between the hydrogen gas / tap water mixer 10 and the hydrogen gas / tap water separator 50, and acts as a pipe that mixes hydrogen gas and tap water and sends them from the hydrogen gas / tap water mixer 10 to the hydrogen gas / tap water separator 50. Here, as explained using Figure 2, inside the hydrogen gas / tap water mixed pipe 40 connected to the hydrogen gas / tap water mixer 10, the tap water level (WH) is controlled to be between the upper end (KH) and the lower end (KL) of the inner diameter of the hydrogen gas / tap water mixed pipe 40. Also, as explained using Figure 3, in order for the hydrogen gas and tap water separator 50 to separate and send out hydrogen gas and tap water, inside the hydrogen gas and tap water mixed pipe 40 connected to the hydrogen gas and tap water separator 50, the tap water level (WH) is located between the upper end (KH) and lower end (KL) of the inner diameter of the hydrogen gas and tap water mixed pipe 40.

[0055] That is, inside the hydrogen gas / tap water mixed pipe 40 extending from the hydrogen gas / tap water mixer 10 to the hydrogen gas / tap water separator 50, there is a continuous space filled with hydrogen gas above the tap water surface (WH).

[0056] In order to satisfy such conditions, the hydrogen gas / tap water mixed pipe 40 is preferably installed horizontally on a plane perpendicular to the direction of gravity. The hydrogen gas / tap water mixed pipe 40 is allowed to have a tilt (a tilt with respect to a plane perpendicular to the direction of gravity) as long as a space filled with hydrogen gas exists between the hydrogen gas / tap water mixer 10 and the hydrogen gas / tap water separator 50, and this condition is satisfied. For example, the hydrogen gas / tap water mixed pipe 40 may have a shape that has a partial tilt between the hydrogen gas / tap water mixer 10 and the hydrogen gas / tap water separator 50.

[0057] When the hydrogen gas / tap water mixed pipe 40 has an inclination (inclination with respect to a plane perpendicular to the direction of gravity), the angle of inclination θ is expressed as follows, assuming that the length of the inclined portion of the hydrogen gas / tap water mixed pipe 40 is L and the inner diameter of the hydrogen gas / tap water mixed pipe 40 (more specifically, the length between the upper end (KH) and the lower end (KL) of the inner diameter of the hydrogen gas / tap water mixed pipe 40) is R: tan θ <R / L It is preferable that the range is set to the above range.

[0058] Furthermore, if the hydrogen gas / tap water mixed pipe 40 has multiple inclines or steps between the hydrogen gas / tap water mixer 10 and the hydrogen gas / tap water separator 50, it is preferable that the range of variation in height (direction of gravity) due to the multiple inclines or steps is less than the inner diameter of the hydrogen gas / tap water mixed pipe 40 between the hydrogen gas / tap water mixer 10 and the hydrogen gas / tap water separator 50.

[0059] The hydrogen gas / tap water mixed delivery system according to the present disclosure has been described above, but the present disclosure is not limited to the above-mentioned embodiment. The above-mentioned embodiment is an example, and any configuration that has substantially the same structure as the technical idea described in the claims of the present disclosure and has similar effects is included in the technical scope of the present disclosure in any case.
