[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In recent years, in order to respond to environmental protection and reduce greenhouse gas emissions, renewable and recyclable new energy sources represented by solar energy, wind energy, hydropower, nuclear energy, biomass energy, geothermal energy, and tidal power generation have developed rapidly. However, the inherent intermittent volatility of renewable energy causes unstable power supply of hydrogen production devices and low hydrogen production efficiency. In addition, the initial design capacity of hydrogen production devices is large, and the investment cost is high.

[0030] Based on this, the embodiment of the present invention provides a flywheel hydrogen production equipment and a flywheel decarbonization system to solve the problems of unstable power supply, low hydrogen production efficiency, and large initial design capacity of the hydrogen production device, resulting in high investment costs. This technology can be applied to hydrogen production devices.

[0031] To facilitate understanding of this embodiment, a flywheel hydrogen production device disclosed in an embodiment of the present utility model is first introduced in detail.

[0032] See also Figure 1 As shown, the embodiment of the present invention provides a flywheel hydrogen production device, comprising: a flywheel device 10, a power generation unit 11, a water electrolysis hydrogen production device 12, a hydrogen storage device 13 and a hydrogen fuel cell 14 connected in sequence, the flywheel device 10 and the hydrogen fuel cell 14 are respectively connected to the output end of the power generation unit 11;

[0033] The power generation unit 11 is used to output a first power source for the water electrolysis hydrogen production device 12; the hydrogen fuel cell 14 is used to convert a portion of the hydrogen in the hydrogen storage device 13 into chemical energy and output a second power source; the flywheel device 10 is used to output a third power source when the first power source and / or the second power source fails, and is also used to adjust the first power source and / or the second power source; the water electrolysis hydrogen production device 12 is used to electrolyze water and transport the hydrogen generated by the electrolysis to the hydrogen storage device 13 for storage.

[0034] The power generation unit 11 is usually a power control cabinet, the water electrolysis hydrogen production device can be an alkaline or PEM (proton exchange membrane) water electrolysis hydrogen production device, and the hydrogen storage device can be a hydrogen storage tank.

[0035] In actual application, the power generation unit 11, the water electrolysis hydrogen production device 12, the hydrogen storage device 13, and the hydrogen fuel cell 14 are connected in sequence. Specifically, the water electrolysis hydrogen production device 12 can convert the alternating current sent by the power generation unit 11 into direct current, and after introducing the water electrolyzer of the water electrolysis hydrogen production device 12, water is decomposed to produce hydrogen and oxygen. The generated hydrogen can then be transported to the hydrogen storage tank through a hydrogen transmission pipeline, and then a part of the hydrogen in the hydrogen storage tank is transported to the anode of the hydrogen fuel cell for the hydrogen fuel cell to generate electricity.

[0036] The above-mentioned hydrogen fuel cell 14 is a power generation device that can directly convert the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is to supply hydrogen and oxygen to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons through the external load to reach the cathode.

[0037] In actual application, the hydrogen fuel cell 14 is connected to the output end of the power generation unit 11. When the power generation unit 11 fails and cannot provide electricity, the hydrogen fuel cell 14 can continue to power the water electrolysis hydrogen production device 12 as a backup power supply, thereby ensuring the normal operation of the water electrolysis hydrogen production device 12 and improving the hydrogen production efficiency. The hydrogen fuel cell 14 is pollution-free to the environment. If hydrogen is generated through renewable energy (photovoltaic panels, wind power generation, etc.), the entire cycle is a process that completely does not produce harmful emissions.

[0038] In actual application, the flywheel device 10 can be connected in parallel to the power generation unit 11 and the hydrogen fuel cell 14. When the electric energy input by the power generation unit 11 and / or the hydrogen fuel cell 14 passes through the flywheel device 10, it drives the flywheel rotor to rotate at high speed, converting the electric energy into the kinetic energy of the flywheel rotor and storing it in the flywheel device 10. When the electric energy emitted by the power generation unit 11 and / or the hydrogen fuel cell 14 fluctuates, due to the inertia of the flywheel, it can compensate for the short-term voltage mutation and maintain the stability of the voltage output. On the other hand, if the power generation unit 11 and / or the hydrogen fuel cell 14 suddenly fails and an interruption occurs, the flywheel device 10 can also convert the kinetic energy into electric energy and provide it to the water electrolysis hydrogen production device 12. Under normal circumstances, the power supply can be maintained for 6-10 seconds.

[0039] The above-mentioned flywheel device 10 has the advantages of faster response speed, higher energy conversion efficiency, and no pollution. The flywheel device 10 can generate a high-power pulse power supply to provide efficient electricity for the water electrolysis hydrogen production device 12, and achieve zero emissions during the power supply process. In actual implementation, the inertia of the flywheel can be used to deal with various abnormalities of the power supply, improve the quality of power, and achieve smooth output of power generation by the power generation unit 11 and / or hydrogen fuel cell 14, thereby ensuring the stability and reliability of power supply, so that the equipment can maintain normal operation and continuously and stably produce hydrogen.

[0040] According to different usage requirements, the power generation unit 11 may include at least one of the following: a renewable energy power generation module 110 and a mains power module 111 .

[0041] In one possible implementation, in order to protect the environment and reduce carbon dioxide emissions, the renewable energy power generation module 110 is first selected as the first power generation option. Renewable energy includes solar energy, wind energy, hydropower, nuclear energy, biomass energy, geothermal energy and tidal energy, etc. The renewable energy power generation module can be a solar photovoltaic panel, a wind power generator, etc. However, in actual implementation, renewable energy is unstable, discontinuous, and fluctuates. For example, when using solar power generation, it may be insufficient or even impossible to generate power due to cloudy weather. When using wind power generation, it may cause spikes and surges due to lightning, resulting in voltage overload. High. If it is transported directly, it is easy to cause damage to the water electrolysis hydrogen production device 12. In response to this situation, a flywheel device 10 can be connected to the output end of the power generation unit 11. When the renewable energy power generation module 110 cannot generate electricity normally, the inertia of the flywheel can be used to convert the stored energy into electrical energy (the third power source) and transmit it to the water electrolysis hydrogen production device 12 to improve the reliability of the power supply. On the other hand, part of the electrical energy can also be converted into kinetic energy to absorb the higher voltage, thereby regulating the electricity (the first power source) generated by the renewable energy power generation module 110 to output a stable voltage and improve the stability of the power supply.

[0042] In actual implementation, the power supply time of the flywheel device is generally very short and cannot be sustained for a long time. Therefore, the hydrogen fuel cell 14 can be used as a second power generation option. The hydrogen generated by the renewable energy power generation module 110 that normally supplies power to the water electrolysis hydrogen production device 12 is provided to the hydrogen fuel cell 14 for power generation (second power source). Since the hydrogen fuel cell 14 is also clean and pollution-free, it can still achieve the purpose of protecting the environment and reducing carbon dioxide. Moreover, using the hydrogen fuel cell 14 as a backup power source can further improve the reliability of power supply.

[0043] In one possible embodiment, the hydrogen fuel cell 14 is connected to the output end of the power generation unit 11. Similarly, during the power supply process of the renewable energy power generation module 110, when the second power supply fails, for example, the hydrogen fuel cell 14 is damaged or the hydrogen supply is insufficient, the inertia of the flywheel can still be used to provide a third power supply or adjust the second power supply to further improve the reliability and stability of the power supply.

[0044] In one possible embodiment, when both the renewable energy generation module 110 and the hydrogen fuel cell 14 are unable to supply power and the energy stored in the flywheel device 10 is exhausted, the mains electricity can be selected as a third power generation option. However, mains electricity generation will cause a large amount of carbon dioxide emissions, affecting the environment. Therefore, it is generally not considered as a necessary backup power source. When the mains electricity is used as the third power generation option, the flywheel can adjust and eliminate the fluctuations of the mains electricity, balance the disturbances of the power grid system, maintain voltage stability, and maintain the dynamic balance of power generation, thereby improving the output power factor and improving the hydrogen production efficiency of the water electrolysis hydrogen production device 12.

[0045] In actual application, considering the random fluctuation of output power caused by the volatility and instability of renewable energy, hydrogen fuel cells and mains electricity, the water electrolysis hydrogen production device 12 often needs to be designed with a large capacity during the initial design, which incurs a high investment cost. However, the present application can utilize the characteristic of the flywheel device to instantly provide peak power, reduce the capacity design, reduce the initial investment and scale cost of the device, and make the device miniaturized and mobile.

[0046] This utility model utilizes the flywheel's inertial output characteristics, along with a hydrogen fuel cell and mains electricity as a backup power source, to ensure trouble-free operation of the entire device. It also reduces design capacity, lowers investment costs, achieves smooth power output, improves power quality, and ensures overall power supply stability and reliability. This allows the water electrolysis hydrogen production device to produce hydrogen continuously and stably, improving hydrogen production efficiency. This solves the technical problems of unstable power supply and low hydrogen production efficiency caused by the inherent intermittent fluctuations of renewable energy, as well as the large initial design capacity and high investment costs of hydrogen production devices.

[0047] The above-mentioned flywheel hydrogen production equipment includes: a flywheel device, a power generation unit, a water electrolysis hydrogen production device, a hydrogen storage device and a hydrogen fuel cell connected in sequence, and the flywheel device and the hydrogen fuel cell are respectively connected to the output end of the power generation unit; the power generation unit is used to output a first power supply for the water electrolysis hydrogen production device; the hydrogen fuel cell is used to convert a portion of the hydrogen in the hydrogen storage device into chemical energy and output a second power supply, and the flywheel device is used to output a third power supply when the first power supply and / or the second power supply fails, and is also used to adjust the first power supply and / or the second power supply; the water electrolysis hydrogen production device is used to electrolyze water and transport the hydrogen generated by electrolysis to the hydrogen storage device for storage: the equipment can utilize the inertial output characteristics of the flywheel to ensure power supply stability, thereby improving hydrogen production efficiency, reducing investment costs, and making the water electrolysis hydrogen production device miniaturized and mobile.

[0048] On this basis, the embodiment of the present invention also provides a flywheel decarbonization system that can be deployed in an enterprise to achieve the purpose of decarbonization and emission reduction without affecting the enterprise's production capacity.

[0049] See also Figure 2 As shown, an embodiment of the present invention provides a flywheel decarbonization system, comprising: a carbon dioxide storage device 20, and any one of the above-mentioned flywheel hydrogen production equipment; the carbon dioxide storage device 20 is used to store carbon dioxide.

[0050] As a preferred embodiment, see Figure 2As shown, the flywheel decarbonization system provided by the embodiment of the present invention also includes a methane generator 22, which is connected to the hydrogen storage device 13 and the carbon dioxide storage device 20 respectively; the methane generator 22 is used to collect hydrogen from the hydrogen storage device 13 and collect carbon dioxide from the carbon dioxide storage device 20, and mix the collected hydrogen and carbon dioxide to carry out a chemical reaction to produce methane.

[0051] In actual implementation, the above-mentioned carbon dioxide storage device 20 can be a carbon dioxide storage tank, and the methane generator 22 can be connected to the hydrogen storage device 13 and the carbon dioxide storage device 20 through pipelines respectively. The hydrogen storage device 13 transports the stored hydrogen to the methane generator 22, and the carbon dioxide storage device 20 transports the stored carbon dioxide to the methane generator 22; hydrogen and carbon dioxide are mixed in the methane generator 22, and undergo a chemical reaction under high temperature and high pressure catalyst conditions to generate methane. The generated methane can be used as fuel and provided to corporate users or individual residential users. In the face of the severe situation of more carbon and less gas, and the high carbon dioxide emissions, the system directly uses carbon dioxide as raw material to synthesize methane, which can not only continuously eliminate carbon dioxide, but also prepare scarce methane energy, realizing true decarbonization.

[0052] As a possible implementation, see Figure 3 As shown, the flywheel decarbonization system provided by the embodiment of the present invention further includes a carbon dioxide separation membrane 23 ; the carbon dioxide separation membrane 23 is connected to the input end of the methane generator 22 through a bypass pipe, and is used to separate the carbon dioxide in the methane generator 22 .

[0053] In actual application, in order to improve the purity of methane, a bypass pipe can be connected to the input end of the methane generator 22. Specifically, a bypass valve can be provided on the bypass pipe. When the bypass valve is opened, the mixed gas in the methane generator 22 reaches the carbon dioxide separation membrane through the bypass pipe to separate the carbon dioxide.

[0054] As a possible implementation, see Figure 4 As shown, the flywheel decarbonization system provided by the embodiment of the present invention also includes a dynamic gas conditioning device 24 and a carbon dioxide collection device 25; the dynamic gas conditioning device 24 is connected to the carbon dioxide separation membrane 23 and the carbon dioxide collection device 25 through pipelines respectively; the carbon dioxide collection device 25 is used to recover carbon dioxide and transport the recovered carbon dioxide to the dynamic gas conditioning device 24; the dynamic gas conditioning device 24 is used to detect and adjust the concentration of mixed carbon dioxide; wherein the mixed carbon dioxide is a mixture of the carbon dioxide separated by the carbon dioxide separation membrane 23 and the carbon dioxide output by the carbon dioxide collection device 25; the dynamic gas conditioning device 24 is also connected to the air inlet of the carbon dioxide storage device 20, and is used to transport the regulated carbon dioxide to the carbon dioxide storage device 20 for storage.

[0055] In actual application, the carbon dioxide collection device 25 can be a carbon dioxide collection tank, a carbon dioxide collection tube or other device for collecting carbon dioxide. The recovered carbon dioxide can be carbon dioxide emitted by enterprises and factories, carbon dioxide generated by burning coal gas in households, etc.

[0056] The carbon dioxide in the carbon dioxide storage device 20 typically needs to reach a certain concentration to rapidly react with hydrogen to produce high-purity methane. Specifically, a dynamic gas conditioning device (DCA device) 24 can be used to monitor and adjust the concentration of the mixed carbon dioxide. Once the carbon dioxide separated by the carbon dioxide separation membrane 23 and the carbon dioxide output from the carbon dioxide collection device 25 meet the required concentration, the carbon dioxide is then transported to the carbon dioxide storage device 20 for recycling, achieving decarbonization.

[0057] As a possible implementation, see Figure 5 As shown, the flywheel decarbonization system provided by the embodiment of the present invention also includes a methane combustion device 26; the methane generator 22, the methane combustion device 26, and the water electrolysis hydrogen production device 12 are connected in sequence; the methane combustion device 26 is used to convert the chemical energy generated by methane combustion to output a fourth power supply for the water electrolysis hydrogen production device 12.

[0058] In actual application, the methane combustion device can be a gas engine. The methane generator can provide the produced methane to the gas engine. The gas engine generates electricity (the fourth power source) and then supplies it to the water electrolysis hydrogen production device 12, thereby realizing efficient utilization of methane.

[0059] As a possible implementation, see Figure 6 As shown, the methane combustion device 26 is also connected to the carbon dioxide separation membrane 23; the carbon dioxide separation membrane 23 is used to separate the carbon dioxide generated by the combustion of methane.

[0060] In actual application, the combustion of methane in the gas engine will produce carbon dioxide. The carbon dioxide produced by the combustion of methane in the gas engine can be separated by a carbon dioxide separation membrane. Therefore, when the gas engine supplies power to the water electrolysis hydrogen production device 12, the generated carbon dioxide will not be discharged into the air, thereby achieving the purpose of reducing carbon dioxide emissions and decarbonizing gas, thereby avoiding the occurrence of the greenhouse effect and protecting the environment.

[0061] As a possible implementation, see Figure 7 As shown, the flywheel decarbonization system provided by the embodiment of the present invention also includes a condenser 27, which is respectively connected to the methane combustion device 26 and the water electrolysis hydrogen production device 12, and is used to convert the water vapor generated by the methane combustion device 26 into liquid water and transport it to the water electrolysis hydrogen production device 12 for electrolysis.

[0062] In actual application, the combustion of methane in the gas engine will also produce water, which will be gasified into water vapor by heat. The generated water vapor can be liquefied into water using a condenser, and then provided to the water electrolysis hydrogen production device 12 for electrolysis to produce raw hydrogen for generating methane.

[0063] The flywheel hydrogen production equipment, carbon dioxide storage device, methane generator, and methane combustion device in the flywheel decarbonization system provided by the embodiment of the present invention are very small in size and can be placed together in a mobile cabin. In actual implementation, the cabin can be moved to the enterprise factory to carry out decarbonization work. Specifically, after green hydrogen is produced by electrolysis, the fuel cell generates power in a closed loop to supply power to the device for producing green hydrogen. At the same time, the flywheel performs power supply regulation and backup power functions, and then the methane generator and the collected carbon dioxide are burned together through the methane combustion device. The carbon dioxide generated in the enterprise factory can be collected through the carbon dioxide collection pipe, and then the collected carbon dioxide and the remaining carbon dioxide in the above-mentioned burner are recycled to the carbon dioxide storage device, and circulated in sequence to finally achieve the neutralization of carbon dioxide, thereby achieving the purpose of reducing carbon dioxide emissions and protecting the environment.
