[0001] This invention belongs to the field of hydrogen energy technology, specifically relating to a liquid hydrogen-liquid nitrogen-electric energy coupling transport system and method based on an impact-resistant disc catalyst structure. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Currently, among the main methods of hydrogen storage and transportation, liquid hydrogen has the highest mass density and is widely used for long-term storage and long-distance transportation. However, some problems also exist in practical transportation applications. For example, application number 202210687613.1, publication number CN...

[0004] Patent 115095790B discloses a hydrogen energy storage and transportation system including production equipment, transportation equipment, and receiving equipment. The production equipment provides liquid hydrogen, the transportation equipment receives the liquid hydrogen produced by the production equipment, and transports it to a designated location where it docks with the receiving equipment. The receiving equipment has a vaporizer that receives the liquid hydrogen from the transportation equipment and converts it into hydrogen gas. Within the vaporizer, the flow direction of the liquid hydrogen can be sequentially divided into a vaporization zone, a low-temperature zone, and a superheated zone. Catalysts for the conversion of secondary to tertiary hydrogen are added to the low-temperature and superheated zones of the feedstock hydrogen, allowing for the conversion of secondary to tertiary hydrogen as the feedstock hydrogen heats up. However, the inventors discovered that in hydrogen energy storage and transportation, especially in onshore liquid hydrogen storage and transportation, when pipelined liquid hydrogen flows into a pipeline filled with secondary to tertiary hydrogen catalyst, strong fluid pulsation impact pressure is generated, causing severe catalyst deformation and thus affecting catalytic and vaporization efficiency.

[0005] Furthermore, with the development of cryogenic pipeline transportation and high-temperature electric superconducting technology, lossless coupling transportation of vapor and electricity using cryogenic working fluids has become possible. Therefore, how to achieve liquid hydrogen-liquid nitrogen-electric energy coupling is also a technical problem that urgently needs to be solved. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a liquid hydrogen-liquid nitrogen-electricity coupled transport system and method based on an impact-resistant disc-shaped catalyst structure. A transition device is added between the pipeline section and the gasification terminal to buffer the impact risk caused by collisions between the transported liquid hydrogen and the pipeline filled with neutral hydrogen catalyst. Simultaneously, due to the heating effect of the transition device, liquid nitrogen is transported in the gap between hydrogen and electricity, achieving coupled hydrogen-nitrogen-electricity transport. This system offers advantages such as strong adaptability, high safety, high transport efficiency, and low cost.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] On one hand, the present invention provides a liquid hydrogen-liquid nitrogen-electricity coupled transport system based on an impact-resistant disc catalyst structure, comprising: a transition section, the front end of which is connected to a pipeline section, and the rear end of which is connected to a terminal; liquid hydrogen from the pipeline section enters the transition section, and the liquid hydrogen is vaporized in the transition section to obtain hydrogen gas, which then enters the terminal.

[0009] The transition section includes, in sequence according to the direction of liquid hydrogen flow, a liquid hydrogen pipeline section, a disc-shaped liquid hydrogen vaporization section, and a catalyst pore hydrogen transport section; wherein, the disc-shaped liquid hydrogen vaporization section is a pipe filled with a secondary-positive hydrogen catalyst and employs a disc-shaped structure.

[0010] Furthermore, the liquid hydrogen pipeline section is a mixed liquid hydrogen and cryogenic superconducting pipeline, including a liquid hydrogen pipeline and cryogenic superconducting channels. Multiple cryogenic superconducting channels semi-enclose the liquid hydrogen pipeline, and the gap areas are filled with cryogenic helium or liquid nitrogen to transfer cold energy.

[0011] Furthermore, the number of liquid hydrogen pipelines can be one or more, with no specific limit, calculated based on the actual pipeline throughput. One pipeline is preferred.

[0012] Furthermore, the number of cryogenic superconducting channels is multiple, with no specific limit, and is calculated based on the actual pipeline throughput. Preferably, there are three channels, which semi-enclose the liquid hydrogen pipeline.

[0013] Furthermore, there are no specific limitations on the diameter of the liquid hydrogen pipeline and the cryogenic superconductor; the diameter is calculated based on the actual situation. The diameter of the liquid hydrogen pipeline is larger than the diameter of the cryogenic superconductor.

[0014] Furthermore, in the liquid hydrogen pipeline section, a secondary-positive hydrogen conversion catalyst is used as the coating on the pipe wall of the liquid hydrogen pipeline.

[0015] Furthermore, in the liquid hydrogen gasification section of the disc-shaped region, the disc structure is arranged in multiple rows from top to bottom, wherein multiple sets of discs are arranged side by side along the vertical direction. There are no special limitations on the discs; the disc structure can be composed of existing discs. The discs are made of a cold-resistant material. The outer wall of the disc is filled with a secondary-positive hydrogen conversion catalyst, resulting in a secondary-positive hydrogen conversion catalyst film coated on the outer wall, forming a disc structure filled with the secondary-positive hydrogen conversion catalyst.

[0016] Furthermore, the dish-shaped liquid hydrogen vaporization section is a gas-liquid two-phase hydrogen and medium-temperature superconducting mixed transport pipeline, including a multiphase hydrogen pipeline and a medium-temperature superconducting pipeline, with the void region filled with medium-temperature helium gas.

[0017] Furthermore, the multiphase hydrogen pipeline consists of multiple pipes of the same diameter. The number of pipes is not specifically limited and is calculated based on the actual pipeline throughput. Preferably, there are seven pipes, with one as the center and the remaining six evenly distributed around it.

[0018] Furthermore, the number of intermediate-temperature superconducting channels is multiple, with no specific limit, and is calculated based on the actual pipeline throughput. Multiple intermediate-temperature superconducting channels semi-enclose the multiphase hydrogen pipeline composed of other pipelines.

[0019] Furthermore, the catalyst pore hydrogen transport section is a hydrogen and high-temperature superconducting mixed transport pipeline, including a hydrogen pipeline and a high-temperature superconducting pipeline, with the pore area filled with liquid nitrogen.

[0020] Furthermore, the walls of the hydrogen pipeline are filled with a large amount of secondary orthohydrogen conversion catalyst.

[0021] Furthermore, the hydrogen pipeline consists of multiple pipes of the same diameter. The number of pipes is not specifically limited and is calculated based on the actual pipeline throughput. Preferably, there are seven pipes, with one as the center and the remaining six evenly distributed around the center pipe.

[0022] Furthermore, the number of high-temperature superconducting channels is multiple, without specific limitation, and is calculated based on the actual pipeline throughput. Multiple high-temperature superconducting channels semi-enclose the hydrogen pipeline composed of multiple channels.

[0023] There are no special restrictions on the materials used for liquid hydrogen pipelines, multiphase hydrogen pipelines, hydrogen pipelines, cryogenic superconducting pipelines, intermediate-temperature superconducting pipelines, and high-temperature superconducting pipelines; conventional round pipes can be used. The specific diameter is determined based on the pipeline's throughput.

[0024] Liquid hydrogen, cryogenic helium, mesotemperature helium, and liquid nitrogen flow in the same direction.

[0025] On the other hand, the present invention provides a liquid hydrogen-liquid nitrogen-electric energy coupling transport method based on an impact-resistant disc catalyst structure, employing the aforementioned liquid hydrogen-liquid nitrogen-electric energy coupling transport system based on an impact-resistant disc catalyst structure, and comprising the following steps:

[0026] Liquid hydrogen from the pipeline section enters the liquid hydrogen pipeline section of the transition section for coupled transport of liquid hydrogen and cryogenic superconductivity, and cold energy is transferred through cryogenic helium or liquid nitrogen filled in the void region.

[0027] Then, it enters the liquid hydrogen vaporization section in the dish-shaped region. The liquid hydrogen enters the dish-shaped structure filled with secondary-positive hydrogen catalyst. At the same time, the secondary-positive hydrogen is converted and the liquid hydrogen is vaporized into a gas-liquid two-phase system, realizing the coupling and transport of gas-liquid two-phase hydrogen with medium-temperature superconducting power. The cold energy is transferred through the medium-temperature helium gas filled in the void region.

[0028] Then, it enters the catalyst pore hydrogen transport section. The gas-liquid two-phase hydrogen enters the hydrogen pipe filled with a large amount of secondary-positive hydrogen conversion catalyst. At the same time, the secondary-positive hydrogen is converted and the gas-liquid two-phase hydrogen is completely vaporized into hydrogen, realizing the mixed transport of hydrogen and high-temperature superconducting. The cold energy is transferred through the low-temperature liquid nitrogen filled in the pore area, and finally the hydrogen energy, liquid nitrogen, cold energy and electrical energy are delivered to the user terminal at the same time.

[0029] Furthermore, in the liquid hydrogen pipeline section, the conversion of secondary positive hydrogen is achieved during the heating process of liquid hydrogen. When carrying out the coupling transport of liquid hydrogen and low-temperature superconducting gas, the gap region is filled with low-temperature helium or liquid nitrogen, and cold energy is transferred through helium.

[0030] Furthermore, in the liquid hydrogen vaporization section of the dish-shaped region, the liquid hydrogen vaporizes into a gas-liquid two-phase system, which is coupled with the intermediate-temperature superconducting power for transport, and the cold energy is transferred through intermediate-temperature helium. When the liquid hydrogen flows through the multiphase hydrogen pipe, it is affected by the impact pressure brought by the buffer hydrogen pipe transport and the vaporization pressure generated by the boiling of liquid hydrogen. As a result, the temperature of the liquid hydrogen gradually increases, and the gas and liquid are transported simultaneously, accompanied by the occurrence of intermediate-hydrogen conversion. When the temperature of the hydrogen rises above the freezing point of nitrogen, it enters the next stage.

[0031] Furthermore, in the catalyst pore hydrogen transport section, during the coupled transport of hydrogen and high-temperature superconductor, cryogenic liquid nitrogen is used to fill the pore region. The transfer of cold energy is achieved through the phase change process of liquid nitrogen. At this time, the hydrogen pipe wall is filled with a large amount of secondary-to-positive hydrogen conversion catalyst. While the hydrogen is heated, the secondary-to-positive hydrogen conversion takes place, continuously releasing cold energy. Liquid nitrogen is continuously transported in the intermediate region between hydrogen and high-temperature superconductor, ultimately realizing the simultaneous delivery of hydrogen energy, liquid nitrogen, cold energy, and electrical energy to the user terminal.

[0032] The transition section for the coupled transport of liquid hydrogen and superconducting power is divided into three stages: the liquid hydrogen pipeline transport section, the liquid hydrogen vaporization section in the dish-shaped region, and the hydrogen transport section through catalyst pores. In these three stages, the temperature of the hydrogen gradually increases, ultimately achieving complete vaporization of liquid hydrogen, secondary hydrogen conversion, efficient transport of liquid nitrogen and electrical energy, and cascade utilization of cold energy. During the coupled transport of liquid hydrogen and cryogenic superconducting power, the pore regions are filled with cryogenic helium or liquid nitrogen, and cold energy is transferred via helium / nitrogen. In long-distance pipeline networks, a mixed transport process of liquid hydrogen and helium with cryogenic superconducting power is used, while in urban pipeline networks, a mixed transport process of cryogenic hydrogen and liquid nitrogen with high-temperature superconducting power is used. A transition section with liquid hydrogen vaporization in the dish-shaped region is used between these two mixed transport processes.

[0033] One or more of the above technical solutions have the following advantages or beneficial effects:

[0034] 1. In hydrogen energy storage and transportation, especially in onshore liquid hydrogen storage and transportation, adding a transition device between the pipeline section and the terminal can buffer the impact risks brought by pipeline liquid hydrogen transportation. At the same time, by filling the liquid hydrogen with a secondary-positive hydrogen conversion catalyst during the liquid hydrogen heating process, the coupling process of secondary-positive hydrogen conversion and gasification in liquid hydrogen can be fully utilized to achieve the cascade utilization of cold energy. That is, by using the heating effect of the transition device, liquid nitrogen can be transported in the gap between hydrogen energy and electrical energy, thus realizing the coupled transportation of hydrogen-nitrogen-electricity.

[0035] 2. During the vaporization of liquid hydrogen in the transition unit, the catalyst structure adopts a disc-shaped structure as a component for absorbing and releasing energy. The disc shape is mainly able to undergo instantaneous deformation to absorb the energy converted from the impact pressure of the pipelined liquid hydrogen, thereby achieving the effect of impact buffering and greatly improving the safety of the entire unit.

[0036] 3. The secondary hydrogen conversion catalyst with a disc-shaped structure expands the catalyst contact area and improves the secondary hydrogen conversion efficiency and heat exchange efficiency.

[0037] 4. The end users of hydrogen energy, liquid nitrogen, cold energy and electricity are almost completely overlapping. This transportation method can ensure safety and timeliness during the large-scale transportation of energy, and improve transportation capacity and flexibility.

[0038] 5. Fully utilize current high-temperature superconducting technology, liquid hydrogen vaporization and cryogenic hydrogen provide cooling, and use liquid nitrogen as an intermediate medium to maintain the temperature environment required for high-temperature superconducting technology, so as to achieve efficient utilization of cold energy in a cascade manner, and couple the superconducting transport of liquid hydrogen, liquid nitrogen, cold energy, cryogenic and high-temperature electricity, greatly reducing the loss of electricity and cold energy.

[0039] 6. Liquid nitrogen is used to fill the void region in the high-temperature superconducting section, enabling efficient transfer of cold energy through liquid nitrogen phase change. Compared to the previously used helium-filled region, liquid nitrogen is less expensive, effectively reducing system costs. Simultaneously, it achieves coupled hydrogen-nitrogen-electrical energy transfer while liquid hydrogen and cold energy are being transported, resulting in high transfer efficiency.

Detailed Implementation

[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to specific embodiments.

[0047] Example 1

[0048] This invention provides a liquid hydrogen-liquid nitrogen-electricity coupled transport system based on an impact-resistant disc catalyst structure, comprising: a transition section, the front end of which is connected to a pipeline section, and the rear end of which is connected to a gasification terminal; liquid hydrogen from the pipeline section enters the transition section, and is gasified in the transition section to obtain hydrogen gas, which then enters the gasification terminal.

[0049] like Figure 1 As shown, the transition section includes, in sequence according to the direction of liquid hydrogen flow, a liquid hydrogen pipeline section, a dish-shaped liquid hydrogen vaporization section, and a catalyst pore hydrogen transport section.

[0050] Within the liquid hydrogen pipeline section, a secondary-to-positive hydrogen conversion catalyst is used as coating 2 on the liquid hydrogen pipeline wall 3, enabling the conversion of secondary-to-positive hydrogen during the liquid hydrogen heating process. This section is a mixed-transmission pipeline for liquid hydrogen and cryogenic superconducting gases; the specific pipeline cross-section is shown below. Figure 2 As shown, the mixed transport pipeline includes a liquid hydrogen pipeline and a cryogenic superconducting pipeline, and the void area is filled with cryogenic helium 12, through which cold energy is transferred.

[0051] There is one liquid hydrogen pipeline. There are three cryogenic superconducting pipelines, which semi-enclose the liquid hydrogen pipeline. The diameter of the liquid hydrogen pipeline is larger than the diameter of the cryogenic superconducting pipeline.

[0052] In the liquid hydrogen vaporization section of the dish-shaped region, unlike the liquid hydrogen pipeline section, the liquid hydrogen pipeline is transformed into a multiphase hydrogen pipeline. At the multiphase hydrogen pipeline wall, an impact-resistant dish-shaped secondary-positive hydrogen conversion catalyst structure is adopted. Specifically, a thin film is formed on the multiphase hydrogen pipeline wall through catalyst coating, which can buffer the impact pressure brought by the liquid hydrogen pipeline transportation and the vaporization pressure generated by the boiling of liquid hydrogen. The liquid hydrogen temperature gradually increases, and gas and liquid are transported simultaneously, accompanied by secondary-positive hydrogen conversion. When the hydrogen temperature rises above the freezing point of nitrogen, it enters the next stage.

[0053] This area is a gas-liquid two-phase hydrogen and medium-temperature superconducting mixed transport pipeline, and the specific pipeline cross-section is as follows. Figure 3 As shown, the mixed-transport pipeline includes a multiphase hydrogen pipeline, a high-temperature superconducting pipeline, and intermediate-temperature helium gas filling the void regions. During the vaporization of liquid hydrogen into a gas-liquid two-phase system, it is coupled with the intermediate-temperature superconducting power for transport, while the transfer of cold energy is still carried out through intermediate-temperature helium gas.

[0054] In the disc-shaped structure 5 filled with a secondary-positive hydrogen conversion catalyst, the disc-shaped structure is arranged in multiple rows from top to bottom, wherein multiple sets of disc-shaped plates are arranged side by side in a vertical direction. Specifically, as shown in... Figure 1 In the middle, three rows are evenly distributed in the liquid hydrogen gasification section of the disc-shaped region. The disc-shaped structure is composed of existing disc-shaped plates. The disc-shaped plates are made of a cold-resistant material, and the outer wall of the disc-shaped plates is coated with a thin film of secondary-positive hydrogen conversion catalyst, forming a disc-shaped structure filled with secondary-positive hydrogen conversion catalyst.

[0055] A multiphase hydrogen pipeline consists of multiple pipes of the same diameter. These pipes are tightly clustered together to form a single unit. There can be up to seven pipes, with one as the central point and the other six evenly distributed around it.

[0056] There are three intermediate-temperature superconducting channels. These channels semi-enclose a multiphase hydrogen pipeline composed of multiple channels, and the gaps are filled with intermediate-temperature helium gas for cold energy transfer.

[0057] In the hydrogen transport section within the catalyst pores, this region is a mixed transport pipeline for hydrogen and high-temperature superconducting gases, with a cross-section as shown below. Figure 4 As shown, the mixed-transport pipeline includes a hydrogen pipeline, a high-temperature superconducting pipeline, and cryogenic liquid nitrogen 14 filling the void regions. The walls of the hydrogen pipeline are filled with a large amount of secondary-positive hydrogen conversion catalyst.

[0058] The hydrogen pipeline consists of seven pipes of the same diameter, arranged in a central configuration with the other six evenly distributed around it.

[0059] The high-temperature superconducting tube has three channels. The multiple channels of the high-temperature superconducting tube surround the hydrogen tube composed of multiple channels in a semi-enclosed shape, and the gap area is filled with liquid nitrogen.

[0060] The pipeline section connects to a gas source to supply liquid hydrogen. A conventional gas source device can be selected.

[0061] Example 2

[0062] This invention provides a liquid hydrogen-liquid nitrogen-electric energy coupling transport method based on an impact-resistant disc catalyst structure, employing the liquid hydrogen-liquid nitrogen-electric energy coupling transport system based on the impact-resistant disc catalyst structure of Example 1, comprising:

[0063] Liquid hydrogen from the pipeline section enters the liquid hydrogen pipeline section of the transition section for coupled transport of liquid hydrogen and cryogenic superconductivity, and cold energy is transferred through cryogenic helium filled in the void region.

[0064] Then, it enters the liquid hydrogen vaporization section in the dish-shaped region. The liquid hydrogen enters the dish-shaped structure filled with secondary-positive hydrogen catalyst. At the same time, the secondary-positive hydrogen is converted and the liquid hydrogen is vaporized into a gas-liquid two-phase system, realizing the coupling and transport of gas-liquid two-phase hydrogen with medium-temperature superconducting power. The cold energy is transferred through the medium-temperature helium gas filled in the void region.

[0065] Then, it enters the catalyst pore hydrogen transport section. The gas-liquid two-phase hydrogen enters the hydrogen pipe filled with a large amount of secondary-positive hydrogen conversion catalyst. At the same time, the secondary-positive hydrogen is converted and the gas-liquid two-phase hydrogen is completely vaporized into hydrogen, realizing the mixed transport of hydrogen and high-temperature superconducting. The cold energy is transferred through the low-temperature liquid nitrogen filled in the pore area, and finally the hydrogen energy, liquid nitrogen, cold energy and electrical energy are delivered to the user terminal at the same time.

[0066] During the above process, the temperature of hydrogen energy gradually increases, eventually achieving complete vaporization of liquid hydrogen, conversion of secondary positive hydrogen, efficient transportation of electrical energy and liquid nitrogen, and cascade utilization of cold energy.

[0067] In the liquid hydrogen pipeline section, the conversion of secondary positive hydrogen is achieved during the heating process of liquid hydrogen. When carrying out the coupling transportation of liquid hydrogen and low-temperature superconducting gas, the void region is filled with low-temperature helium gas, and the cold energy is transferred through helium gas.

[0068] In the liquid hydrogen vaporization section of the dish-shaped region, the liquid hydrogen vaporizes into a gas-liquid two-phase system, which is coupled with the intermediate-temperature superconducting power for transport, and the cold energy is transferred through intermediate-temperature helium. As the liquid hydrogen flows through the multiphase hydrogen pipe, the impact pressure from the buffer hydrogen pipe transport and the vaporization pressure generated by the boiling of the liquid hydrogen cause the liquid hydrogen temperature to gradually increase. Gas and liquid are transported simultaneously, accompanied by the occurrence of intermediate-hydrogen conversion. When the hydrogen temperature rises above the freezing point of nitrogen, it enters the next stage.

[0069] In the hydrogen transport section within the catalyst pores, during the coupled transport of hydrogen and the high-temperature superconductor, cryogenic liquid nitrogen is used to fill the pore region. The transfer of cold energy is achieved through the phase change process of liquid nitrogen. Meanwhile, the hydrogen pipe wall is filled with a large amount of secondary orthohydrogen conversion catalyst. As the hydrogen heats up, secondary orthohydrogen conversion occurs, continuously releasing cold energy. Liquid nitrogen is continuously transported in the intermediate region between the hydrogen and the high-temperature superconductor, ultimately achieving the simultaneous delivery of hydrogen energy, liquid nitrogen, cold energy, and electrical energy to the user terminal.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
