Description

[Technical field]

[0001] The present invention relates to a hydrogen / oxygen generating device that generates hydrogen gas and oxygen gas by electrolysis of water, and a heating device that burns the hydrogen gas and oxygen gas generated in the hydrogen / oxygen generating device and utilizes the combustion heat. [Background technology]

[0002] The use of hydrogen gas as a clean energy source has been attracting attention. One method of producing hydrogen gas is to react hydrocarbons such as methane contained in petroleum and natural gas with water steam to produce hydrogen and carbon dioxide (CO 2 Well-known methods include the steam reforming method, in which water is separated into hydrogen and oxygen, and the electrolysis method, in which water is separated into hydrogen and oxygen by passing an electric current through it.

[0003] Although the steam reforming method can produce large amounts of hydrogen gas, it uses fossil fuels as the raw material, and therefore produces carbon dioxide (CO 2 ) was a problem. On the other hand, electrolysis, a method of generating hydrogen that does not use fossil fuels as a raw material, uses a hydrogen / oxygen generator equipped with a water electrolysis module that generates hydrogen gas and oxygen gas as product gases by electrolyzing water. Conventionally, in electrolysis, since water does not easily conduct electricity, the efficiency of hydrogen gas generation can generally be increased by adding a strong alkaline solution such as potassium hydroxide or sodium hydroxide to the water as a catalyst.

[0004] In recent years, a hydrogen combustion type hot air generation method and a hydrogen combustion type hot air heater have been proposed in which hydrogen gas generated in a hydrogen / oxygen generation device using a method of adding a strong alkaline solution as a catalyst to water is mixed with oxygen gas and burned, and hot air is generated using the combustion heat (see Patent Document 1).

[0005] In the hydrogen combustion type hot air generating method and hydrogen combustion type hot air heater described in Patent Document 1, in the electrolysis device that generates hydrogen gas and oxygen gas, potassium hydroxide is added to water to promote the electrolysis of water. In addition, in the combustion section, when the generated hydrogen gas is mixed with oxygen gas, air is also introduced and mixed. The oxygen contained in the introduced air is combusted with the hydrogen gas, and the air is heated at the same time. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 4671232 Summary of the Invention [Problem to be solved by the invention]

[0007] The electrolysis process described in Patent Document 1 uses a method of adding a potassium hydroxide solution as a catalyst to water, but this potassium hydroxide solution is a toxic substance that is dangerous to the human body, so its use should be avoided, especially in hydrogen generation devices for general household use. Therefore, there is a demand for an electrolysis device that safely and efficiently generates hydrogen gas and oxygen gas.

[0008] Furthermore, in the hydrogen combustion type hot air generation method and hydrogen combustion type hot air heater described in Patent Document 1, when hydrogen gas is burned, air is also introduced in addition to the oxygen gas produced by electrolysis for combustion and heating, which causes the problem of generating nitrogen oxides (NOx), just like conventional hydrogen combustion systems that use oxygen in the air.

[0009] Therefore, the present invention is intended to solve the above-mentioned problems of the prior art, and its object is to provide a hydrogen and oxygen generating device that generates hydrogen gas and oxygen gas safely and efficiently without using a strong alkaline solution.

[0010] Another object of the present invention is to provide a heating device that uses hydrogen gas and oxygen gas produced by electrolysis of water, obtains thermal energy without using oxygen in the air, and utilizes the heat of combustion of hydrogen without emitting carbon dioxide or nitrogen oxides. [Means for solving the problem]

[0011] According to the present invention, a hydrogen / oxygen generation device includes a water electrolysis cell having a solid polymer electrolyte membrane and a cathode-side electrode plate and an anode-side electrode plate respectively arranged on both sides of the solid electrolyte membrane, and which electrolyzes raw water supplied to the anode-side electrode plate to generate hydrogen gas and oxygen gas. The anode-side electrode plate has a plurality of grooves formed in a predetermined pattern on its surface on which the solid polymer electrolyte membrane is arranged, and the plurality of grooves form a plurality of passages connecting the inlet and outlet of the raw water on the anode-side electrode plate.

[0012] In a water electrolysis cell that generates hydrogen gas and oxygen gas, a plurality of grooves are formed in a predetermined pattern on the surface of the anode side electrode plate on which the solid polymer electrolyte membrane is disposed, and the plurality of grooves form a plurality of passages connecting the inlet and outlet of raw water on the anode side electrode plate, thereby increasing the contact area between the raw water and the anode side electrode plate and achieving substantially the same hydrogen gas production efficiency without adding a strong alkaline solution as a catalyst. In addition, because no strong alkaline solution is used, hydrogen gas and oxygen gas can be generated safely and efficiently.

[0013] It is preferable that a plurality of water electrolysis cells are connected in parallel, so that sufficient amounts of hydrogen gas and oxygen gas can be generated.

[0014] It is also preferable to further comprise a hydrogen gas recovery means and an oxygen gas recovery means for respectively recovering the hydrogen gas and oxygen gas generated in the plurality of water electrolysis cells, whereby the hydrogen gas and oxygen gas generated in the plurality of water electrolysis cells can be collectively recovered and stored in a hydrogen gas tank and an oxygen gas tank.

[0015] According to the present invention, a heating device that utilizes the heat of hydrogen-oxygen combustion comprises a hydrogen-oxygen generation device of the present invention and a combustion means that burns only the hydrogen gas and oxygen gas generated in the hydrogen-oxygen generation device without using oxygen in the outside air, and is configured to heat a specified space using the combustion heat generated by the combustion means.

[0016] By burning the hydrogen gas and oxygen gas generated in the hydrogen-oxygen generator, it is possible to provide a heating device that obtains thermal energy without using oxygen in the air and uses the heat of hydrogen combustion without emitting carbon dioxide or nitrogen oxides.In addition, there is no risk of carbon monoxide poisoning when used as a heating device, so there is no need for indoor ventilation.

[0017] The combustion means has a combustion burner consisting of at least one combustion nozzle, and the combustion nozzle preferably has an oxygen gas outlet for ejecting oxygen gas at its center and a ring-shaped hydrogen gas outlet for ejecting hydrogen gas provided on the outer periphery of the oxygen gas outlet, thereby making it possible to combust hydrogen gas efficiently.

[0018] It is preferable to further include a humidifying means for humidifying a predetermined space heated by the heat of combustion by using water vapor generated when hydrogen gas and oxygen gas are combusted by the combustion means. Since the exhaust gas when hydrogen gas and oxygen gas are combusted is water vapor, by appropriately releasing this water vapor into the room, it is possible to provide not only a heating function as a heating device but also a humidifying function. Effect of the Invention

[0019] According to the present invention, the hydrogen / oxygen generating device is a water electrolysis cell that generates hydrogen gas and oxygen gas, in which a plurality of grooves are formed in a predetermined pattern on the surface of the anode side electrode plate on which the solid polymer electrolyte membrane is disposed, and the plurality of grooves form a plurality of passages connecting the inlet and outlet of the raw water on the anode side electrode plate, thereby increasing the contact area between the raw water and the anode side electrode plate, and achieving substantially the same hydrogen gas generation efficiency without adding a strong alkaline solution as a catalyst. Also, since no strong alkaline solution is used, hydrogen gas and oxygen gas can be generated safely and efficiently.

[0020] According to the present invention, a heating device that utilizes the heat of hydrogen-oxygen combustion includes the hydrogen-oxygen generator of the present invention and a combustion means that uses only hydrogen gas and oxygen gas generated by the hydrogen-oxygen generator without using oxygen in the outside air, and is configured to heat a specified space using the combustion heat generated by the combustion means, so that a heating device that obtains thermal energy without using oxygen in the air and utilizes the combustion heat of hydrogen without emitting carbon dioxide or nitrogen oxides can be provided. In addition, there is no risk of carbon monoxide poisoning when used as a heating device, so there is no need for indoor ventilation. In addition, since no strong alkaline solution is used, it can be used at home, on a farm (greenhouse, house), etc. [Brief description of the drawings]

[0025] The raw water storage tank 10 is for storing raw water (e.g., pure water or purified water) and is formed to have a predetermined capacity as required. The raw water storage tank 10 also has a raw water outlet and an inlet through which raw water circulated from the water electrolysis cell 30 flows. The raw water outlet is connected to a pump 20.

[0028] The anode end plate 31 is provided with a raw water supply port 31a for supplying raw water and a water / oxygen outlet 31b for discharging raw water and generated oxygen gas, while the cathode end plate 32 is provided with a hydrogen outlet 32a for discharging generated hydrogen gas.

[0029] The anode side electrode plate 33 is provided with a raw water supply port 33a for supplying raw water and a water / oxygen discharge port 33b for discharging raw water and the generated oxygen gas. As shown in FIG. 3, a plurality of grooves 33c are formed in a predetermined pattern on the surface of the anode side electrode plate 33 on which the solid polymer electrolyte membrane 36 is disposed, and these grooves 33c are configured to form a plurality of passages connecting the raw water supply port 33a for raw water and the water / oxygen discharge port 33b on the anode side electrode plate 33. As a result, raw water is evenly supplied to the entire surface of the anode side electrode plate 33, the contact area between the raw water and the anode side electrode plate 33 is increased, and the raw water can be electrolyzed into hydrogen gas and oxygen gas with higher generation efficiency without adding a strong alkaline solution as a catalyst, and as a result, hydrogen gas can be obtained. On the other hand, the cathode side electrode plate 34 is provided with a hydrogen discharge port 32a for discharging the generated hydrogen gas. In this embodiment, the anode side electrode plate 33 and the cathode side electrode plate 34 are formed of a metal material having excellent conductivity, such as titanium.

[0030] The porous power feeders 35A and 35B are made of titanium and have a porous structure. These porous power feeders 35A and 35B are arranged to sandwich the solid polymer electrolyte membrane 36 in order to supply raw water and electricity to the solid polymer electrolyte membrane 36.

[0031] The solid polymer electrolyte membrane 36 is made of a solid polymer material as an electrolyte material, and may be, for example, a proton-conductive ion exchange membrane formed of a fluororesin or a hydrocarbon resin material. More specifically, it may be a membrane made of Nafion (registered trademark), a perfluoro electrolyte. A catalyst 36a is applied to the surface of the solid polymer electrolyte membrane 36. Oxygen gas and hydrogen gas are generated by electrolysis of raw water (for example, pure water or purified water) using this solid polymer electrolyte membrane 36.

[0032] The silicone pads 37A and 37B are disposed between the anode end plate 31 and the anode electrode plate 33, and are packings that insulate the anode end plate 31 from the anode electrode plate 33.

[0034] The tightening screw set 39 includes a bolt 39a, a washer 39b, a spring washer 39c, and a nut 39d. An insulating tube 39e is attached to the bolt 39a.

[0035] The electrolysis power supply 40 is a DC stabilized power supply that supplies power to the anode side electrode plate 33 and the cathode side electrode plate 34. In this embodiment, for example, the voltage supplied from the electrolysis power supply 40 to the water electrolysis cell 30 is set to a maximum of 36 (V), and the current is set to a maximum of 42 (A). Note that natural energy such as solar power, wind power, or wave power can be used as the power for the electrolysis power supply 40.

[0036] The gas-liquid separator 50 is installed downstream of the water / oxygen outlet 31b for discharging the raw water of the water electrolysis cell 30 and the generated oxygen gas, and separates the raw water and oxygen gas circulated from the water electrolysis cell 30. This gas-liquid separator 50 functions as a part of the oxygen gas recovery means. The oxygen gas separated by the gas-liquid separator 50 is collected in the oxygen gas storage tank 60, and the separated raw water is returned to the raw water storage tank 10. The oxygen gas recovery means also has an oxygen gas recovery pipeline, etc.

The hydrogen gas generated from the multiple water electrolysis cells 30 is collected collectively by hydrogen gas collection means composed of a hydrogen gas collection pipeline or the like, and is stored in the hydrogen gas storage tank 70.

[0039] The control means controls the raw water supply pump 20 and the electrolysis power supply 40, and is, for example, a microcomputer. This microcomputer controls the overall operation of the hydrogen / oxygen generation device 100 in accordance with a control program. In this embodiment, the control means is configured to control the operation of the raw water supply pump 20 and the electrolysis power supply 40 when a user turns on the power supply, so as to supply the raw water to the water electrolysis cell 30 at a flow rate necessary for generating hydrogen gas, and to supply a predetermined amount of power.

In the water electrolysis cell 30, the anode side electrode plate 31 has a surface on which the solid polymer electrolyte membrane 36 is disposed, on which a plurality of grooves 33c are formed in a predetermined pattern, and the plurality of grooves 33c form a plurality of passages connecting the inlet 33a and the outlet 33b of the raw water on the anode side electrode plate 33, so that the contact area between the raw water and the anode side electrode plate 33 is increased, and the hydrogen gas generation efficiency can be almost the same even without adding a strong alkaline solution as a catalyst. In addition, since a strong alkaline solution is not used, hydrogen gas and oxygen gas can be generated safely and efficiently.

[0041] Furthermore, by configuring the water electrolysis cells 30 by connecting them in parallel, sufficient amounts of hydrogen gas and oxygen gas can be generated.

[0042] It is also preferable to further provide a hydrogen gas recovery means and an oxygen gas recovery means for respectively recovering the hydrogen gas and oxygen gas generated in the plurality of water electrolysis cells 30. This allows the hydrogen gas and oxygen gas generated in the plurality of water electrolysis cells 30 to be collectively recovered and stored in the hydrogen gas tank 60 and the oxygen gas tank 70. Note that the hydrogen gas and oxygen gas generated in the water electrolysis cells 30 may be directly used without providing storage tanks for hydrogen gas and oxygen gas.

[0043] Hereinafter, an embodiment of a heating device 100A utilizing the heat of combustion of hydrogen using the hydrogen / oxygen generation device 100 of the present invention will be described.

[0044] FIG. 4 shows a schematic configuration of a heating device 100A that utilizes heat from hydrogen-oxygen combustion in one embodiment of the present invention, and FIG.

[0045] 4 and 5, a heating device 100A that utilizes heat from hydrogen-oxygen combustion according to this embodiment includes a hydrogen-oxygen generation device 100, a combustion burner 80 consisting of at least one combustion nozzle as a combustion means, and a combustion chamber 90. In this embodiment, an oxygen gas storage tank 60 of the hydrogen-oxygen generation device 100 is connected to the combustion burner 80 via a flow rate control valve 61, and a hydrogen gas storage tank 70 is connected to the combustion burner 80 via a flow rate control valve 71 and a flashback prevention valve 72. The flashback prevention valve 72 is for preventing flashback from the combustion burner 80 to the hydrogen gas storage tank 70.

[0046] Here, the above-mentioned hydrogen / oxygen generating device 100 of the present invention is used. The hydrogen / oxygen generating device 100 has a similar configuration to the above-mentioned embodiment, so a detailed description thereof will be omitted.

[0047] As shown in FIG. 5, the combustion burner 80 is composed of a combustion nozzle main body 80a having an oxygen gas outlet 81 at the center for ejecting oxygen gas, and a cover member 80b that is attached to the upper end of the combustion nozzle main body 80a and forms a hydrogen gas outlet 82. A tapered surface 80c is provided on the upper part of the cover member 80b. In this embodiment, the combustion burner 80 is provided with the oxygen gas outlet 81, a ring-shaped hydrogen gas outlet 82 that is provided on the outer periphery of the oxygen gas outlet 81 and ejects hydrogen gas, and a plurality of (for example, three) auxiliary hydrogen gas outlets 83 that are provided on the outer periphery of the hydrogen gas outlet 82. The oxygen gas outlet 81 is located at the center of the combustion nozzle main body 80a, and its upper end is a cylindrical protrusion. In addition, the combustion nozzle main body 80a is provided with a passage through which oxygen gas passes and a passage through which hydrogen gas passes. Hydrogen gas is ejected from the hydrogen gas outlet 82 and the plurality of auxiliary hydrogen gas outlets 83.

[0048] Here, since the tapered surface 80c is provided on the upper part of the cover member 80b, the water generated by the combustion of hydrogen easily flows down from the tapered surface 80c, and is prevented from condensing and staying on the upper surface of the combustion burner 80. This makes it possible to suppress the generation of rust during the combustion of hydrogen and to extend the life of the device. Furthermore, it is possible to suppress the decrease in combustion efficiency that accompanies the decrease in temperature of the combustion burner 80 due to the condensation of water.

[0049] The combustion chamber 90 is formed to cover the combustion burner 80, and constitutes a combustion space for hydrogen gas and oxygen gas, and also has the effect of suppressing the generation of nitrogen oxides by preventing contact with outside air. A water vapor outlet is provided at the top of the combustion chamber 90 to discharge water vapor generated by the combustion of hydrogen gas and oxygen gas. The combustion chamber 90 may be configured to include a humidifying means that uses the water vapor discharged from the water vapor outlet of the combustion chamber 90 to humidify a predetermined space heated by the heat of combustion.

[0050] It is also possible to provide a ceramic plate, which is expected to have a far-infrared effect, on the outer surface of the combustion chamber 90 and heat the ceramic plate to indirectly generate hot air.

[0051] As described above, the heating device 100A using the heat of hydrogen-oxygen combustion of this embodiment includes the hydrogen-oxygen generating device 100, the combustion burner 80 consisting of at least one combustion nozzle as a combustion means, and the combustion chamber 90, and is configured to heat a specified space using the combustion heat generated by the combustion means, so that a heating device can be provided that obtains thermal energy without using oxygen in the air and uses the combustion heat of hydrogen without emitting carbon dioxide or nitrogen oxides. In addition, when used as a heating device, oxygen in the room is not used, so there is no need to ventilate the room. In addition, since a strong alkaline solution is not used, it can be used at home, on a farm (greenhouse, house), etc.

[0052] In this embodiment, a hydrogen and oxygen generator 100 is used to generate hydrogen gas and oxygen gas by electrolyzing water, so that only the required amount of water can be electrolyzed when needed, and high-purity hydrogen gas and oxygen gas can be separated and generated. In addition, the heating device 100A that utilizes the heat of hydrogen combustion in this embodiment is a combustion system that does not use oxygen in the air, so that it can obtain thermal energy by combustion even in airless conditions such as in space or underwater.

[0053] The combustion means has a combustion burner consisting of at least one combustion nozzle, and the combustion burner 80 is equipped with an oxygen gas outlet 81, a ring-shaped hydrogen gas outlet 82 for ejecting hydrogen gas provided on the outer periphery of the oxygen gas outlet 81, and a plurality of auxiliary hydrogen gas outlets 83 provided on the outer periphery of the hydrogen gas outlet 82. This allows the hydrogen gas to be burned efficiently.

[0054] Furthermore, the device is further provided with a humidification means for humidifying a specified space heated by the heat of combustion using water vapor generated when hydrogen gas and oxygen gas are combusted by the combustion means. Since the exhaust gas generated when hydrogen gas and oxygen gas are combusted is water vapor, by appropriately releasing this water vapor into the room, the device can have not only a heating function as a heating device but also a humidifying function.

[0055] In the above embodiment, the anode side electrode plate 33 is formed with a plurality of grooves 33c having a concentric circular pattern as shown in Fig. 3, but the present invention is not limited to this. For example, as shown in Fig. 6, the anode side electrode plates 33A and 33B may be configured to have a plurality of grooves 33d and 33e having patterns as shown in (A) and (B) in the figure.

[0056] In the above embodiment, the hydrogen / oxygen generation device 100 has two water electrolysis cells 30, but the present invention is not limited to this. One or three or more water electrolysis cells 30 may be used as necessary.

[0057] In the above embodiment, the combustion burner 80 of the heating device 100A that utilizes the heat of hydrogen-oxygen combustion has one combustion nozzle, but the present invention is not limited to this. If necessary, two or more combustion nozzles may be provided.

[0058] The present invention is not limited to the above-described embodiments, and its technical scope includes various modified forms of design within the scope that does not deviate from the gist of the invention described in the claims. [Industrial Applicability]
