Description

Technical Field

[0001] The present invention belongs to the technical field of geothermal energy utilization, and specifically relates to a hydrogen production device based on geothermal energy utilization and a use method thereof. Background Art

[0002] With the continuous growth of energy demand and the increasing awareness of environmental protection, finding and utilizing clean and sustainable forms of energy has become a global urgent task. As a huge source of energy hidden in the earth's interior, the development and utilization of geothermal energy is of great significance to alleviating the depletion of fossil energy, reducing greenhouse gas emissions, and promoting the transformation of energy structure. Geothermal energy is not only abundant in reserves, but also widely distributed, and is almost unrestricted by geographical location and climatic conditions. It is a renewable energy source with great potential. With the advancement of science and technology and the global pursuit of sustainable development goals, the efficient development and utilization of geothermal energy is gradually becoming a research hotspot in the energy field and is regarded as an important part of the future energy system.

[0003] In recent years, the development and utilization technology of geothermal energy has made significant progress. In terms of direct utilization of geothermal energy, such as heating, hot spring therapy and other fields, the technology has become relatively mature, providing stable and comfortable energy services for local residents. In the field of geothermal power generation, scientists are constantly exploring more efficient and environmentally friendly power generation technologies, including dry steam power generation, flash evaporation power generation, binary cycle power generation and other methods, aiming to improve the efficiency and economy of geothermal power generation. At the same time, in order to overcome the geographical limitations of geothermal power generation, researchers are also exploring long-distance heat transmission technology, the comprehensive utilization of geothermal energy and other renewable energy technologies, etc., in order to achieve a wider and more flexible application of geothermal energy.

[0004] Although geothermal energy development and utilization technology has made many progress, it still faces a series of challenges and problems. First, the concentrated areas of geothermal power generation are often not matched with densely populated areas and areas with high electricity demand, resulting in large losses in the process of power transmission, affecting the economy and practicality of geothermal power generation. Secondly, the output characteristics of geothermal power generation are stable and uniform, while the electricity consumption in densely populated areas fluctuates greatly with factors such as season and time. This mismatch between supply and demand makes the scheduling and storage of geothermal power generation a problem. In particular, there is currently a lack of efficient, economical, and large-scale solutions for electricity storage technology, which limits geothermal power generation in responding to peak and valley demands of the power grid and improving energy utilization. Therefore, how to effectively solve the transmission loss, supply and demand matching, and electricity storage problems of geothermal power generation has become a technical difficulty that needs to be overcome in the current field of geothermal energy development and utilization. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a hydrogen production equipment and a method of use based on geothermal energy utilization, so as to solve the technical problem of how to effectively convert geothermal energy into hydrogen energy that is easy to store and transport, so as to reduce transportation losses and optimize energy storage.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention discloses a hydrogen production device based on geothermal energy utilization, comprising: a power generation component, an electrolysis component electrically connected to the power generation component, and a hydrogen storage component connected to the electrolysis component; The electrolysis component includes a water storage chamber, an electrode installed in the water storage chamber, and a hydrogen transmission pipe installed above the water storage chamber; the electrode is electrically connected to the power generation component; the hydrogen transmission pipe is connected to the electrolysis component to transmit the hydrogen generated by electrolysis to the hydrogen storage component; A hollow portion is provided on the side of the water storage chamber to discharge the generated oxygen; The power generation component includes: a transformer, a generator electrically connected to the transformer, a turbine fixedly connected to the rotating shaft of the generator, and a production well and an injection well connected to the turbine through a pipeline.

[0007] Preferably, the hydrogen storage component includes a compressor and a hydrogen tank connected to the hydrogen transmission pipe through the compressor.

[0008] Further preferably, the compressor is an air compressor; an air source triplex is provided between the hydrogen tank and the compressor to purify the hydrogen.

[0009] Preferably, the electrode is located at the bottom of the water storage cavity and obliquely below the hollow portion; A water inlet pipe is arranged on the side of the water storage chamber to provide clean water to the water storage chamber.

[0010] Preferably, the hydrogen delivery pipe is located directly above the electrode and obliquely above the hollow portion.

[0011] Preferably, the hydrogen delivery tube is conical, with the larger end facing the electrode; the hydrogen delivery tube is made of a good conductor to condense the water vapor generated in the water storage chamber and return it to the water storage chamber.

[0012] Preferably, the injection well is connected to the production well through a pipeline, and the pipeline between the production well and the injection well contacts the geothermal source; The injection well is used to inject clean water into the pipeline at the geothermal source, and the production well is used to receive water vapor from the geothermal source and pass the water vapor to the turbine, which is used to discharge the water vapor; The transformer is electrically connected to the electrode.

[0013] The present invention also discloses a method for using the above-mentioned hydrogen production equipment based on geothermal energy utilization, comprising the following steps: S1. The external control system continuously passes clean water into the injection well. Under the action of gravity, the injection well discharges the clean water into the pipeline at the geothermal source. After the clean water in the pipeline is heated, the generated water vapor reaches the production well through the pipeline; S2. As water vapor is continuously generated, the water vapor pressure at the production well becomes larger and larger, thereby sending the water vapor to the turbine and driving the turbine to work. The turbine drives the generator to work and generate electricity. The generator transmits the generated electricity to the transformer, and the transformer converts the electricity into DC or AC with a stable voltage to supply the electrodes for electrolysis; S3. After the electrode is powered on, the water in the water storage chamber is electrolyzed into hydrogen and oxygen. During the electrolysis process, the hydrogen and oxygen continue to increase. The hydrogen with low density reaches the hydrogen transmission pipe, while the oxygen with high density stays at the bottom. The excess oxygen is discharged through the hollow part. S4. Hydrogen is transported to the hydrogen storage component through the hydrogen transport pipe, and steps S1 to S3 are maintained until the work is completed.

[0014] Preferably, the injection well and the production well are both located on the ground and fixedly connected to the ground; Transformers and generators are located away from electrolytic components.

[0015] Preferably, the hydrogen tank is a high-pressure gas storage tank; The hydrogen transmission pipe is far away from the generator, transformer and electrolysis components.

By integrating power generation components, electrolysis components and hydrogen storage components, the conversion and storage of geothermal energy from electric energy to hydrogen energy are realized, and the storage and transportation problems encountered in direct utilization of geothermal energy or traditional power generation methods are solved. The energy utilization efficiency is improved, and the storability and transportability of energy are enhanced. The electrolysis component enables the electric energy generated by geothermal power generation to be directly used for the electrolysis reaction of water to generate hydrogen and oxygen. The direct electrical connection between the electrode and the power generation component ensures the high efficiency of energy conversion, and the hydrogen transmission pipe facilitates the timely output of the generated hydrogen, which provides convenience for subsequent storage and utilization. The hydrogen transmission pipe ensures the smooth transmission of hydrogen from the electrolysis component to the hydrogen storage component, reduces the loss of hydrogen during the transmission process, and improves the safety and reliability of the entire system. At the same time, it also provides the possibility of long-term storage and on-demand use of hydrogen. The hollow part on the side of the water storage chamber allows the oxygen generated during the electrolysis process to be discharged smoothly, avoiding the accumulation of oxygen in the water storage chamber, thereby ensuring the continuous electrolysis reaction and the stable operation of the system. At the same time, this also simplifies the structure of the system and reduces maintenance costs. The transformer ensures the stable output of electric energy, and the direct connection between the generator and the turbine improves the energy conversion efficiency. The production well and the injection well are connected to the turbine through a pipeline, forming a geothermal energy recycling system, which not only improves the utilization rate of geothermal energy, but also reduces the waste of geothermal energy. The present invention uses power generation components, electrolysis components and hydrogen storage components in coordination with each other to produce hydrogen production equipment based on geothermal energy utilization and a method of use instead of converting the generated electric energy into hydrogen energy, so as to facilitate the storage of energy in the process of geothermal energy utilization, facilitate the practical effect in the later stage, avoid excessive losses during transportation, and facilitate energy storage.

[0017] The present invention also discloses a method for using a hydrogen production device based on geothermal energy utilization. Through the precise control of an external control system, the effective injection and heating of clean water are achieved, thereby generating water vapor. Not only does it make full use of the natural characteristics of geothermal energy, but also through the design of the pipeline, it ensures the effective transmission of water vapor to the production well, providing a stable and reliable heat source for the subsequent power generation process. At the same time, the effect of gravity makes the whole process more energy-saving and efficient. Through the continuous heating of the geothermal source, the water vapor pressure gradually increases, driving the turbine to rotate, and then driving the generator to generate electricity. The role of the transformer ensures the stable output of electric energy to meet the electric energy demand of electrode electrolysis. Not only does it achieve efficient conversion of geothermal energy, but also through the stable output of electric energy, it provides a reliable energy guarantee for subsequent electrolytic hydrogen production. After the electrode is powered on, the water in the water storage cavity is electrolyzed into hydrogen and oxygen, realizing the conversion of electrical energy to chemical energy. At the same time, through the density difference between oxygen and hydrogen, the effective collection of hydrogen and the discharge of oxygen are realized. The water replenishment mechanism of the external control system ensures the continuous progress of the electrolysis process and improves the efficiency of hydrogen production. The design of the hydrogen transmission pipe ensures that hydrogen can smoothly reach the hydrogen storage component for storage. Not only does it achieve effective storage of hydrogen energy, but by maintaining the continuity of the above-mentioned process, it ensures the stability and efficiency of the entire hydrogen production process. At the same time, the design of the hydrogen storage component also facilitates the subsequent use of hydrogen energy.
