[0002] With the development of industry and the improvement of people's living standards, the demand for energy is also increasing day by day. In recent decades, the energy used mainly comes from fossil fuels, such as coal, oil, natural gas, etc., and their use inevitably pollutes the environment. In addition, their reserves are limited, and the search for renewable green energy has become urgent. Hydrogen energy, as a green energy and energy carrier with abundant reserves, wide sources, and high energy density, has been increasingly valued and applied by people. When using hydrogen energy, the following processes are required: hydrogen production, storage, transportation, and application, and the storage and transportation of hydrogen energy is a key part of hydrogen energy applications. Solid-state hydrogen storage uses the physical adsorption or chemical reaction of solids on hydrogen to store hydrogen in solid materials. Solid-state hydrogen storage has the advantages of safety, high efficiency, and high density. It is the most promising hydrogen storage process after gaseous storage and liquid storage.

[0003] At present, solid-state hydrogen storage tanks are used in many markets. Among them, solid-state hydrogen storage tanks need to be activated during the hydrogen storage process to improve the hydrogen storage efficiency. In order to have good thermal conductivity, solid-state hydrogen storage tanks are usually made of aluminum alloy. When they are in direct contact with water during the heating and activation process, they will oxidize and turn black, which will affect the activation efficiency of the solid-state hydrogen storage tank. Therefore, how to ensure the good thermal conductivity of the solid-state hydrogen storage tank while enhancing the activation efficiency of the solid-state hydrogen storage tank is a key issue in improving the hydrogen storage efficiency of the solid-state hydrogen storage tank.

At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] Please refer to Figures 1 to 4As shown, the present application provides a multi-station solid-state hydrogen storage tank activation device, including an activation box 1, wherein the activation box 1 is penetrated by a plurality of station barrel tubes 2 along the thickness direction, the axial outer wall of each station barrel tube 2 is kept flush with the end face of the activation box 1 on the same side and is sealed, and gaps are left between adjacent station barrel tubes 2, and between the radial outer walls of the station barrel tubes 2 and the inner walls of the activation box 1 facing the radial outer walls of the station barrel tubes 2, and are connected to form a heat exchange inner cavity 8; an inlet 3 is provided on the bottom outer wall of the activation box 1, and an outlet 4 is provided on the top outer wall of the activation box 1, and the inlet 3 and the outlet 4 are connected to hot and cold water machines; the station barrel tube 2 is a tubular structure with an axial through hole, and a solid-state hydrogen storage tank is placed in each station barrel tube 2, and the solid-state hydrogen storage tank is connected to a vacuum device and a hydrogen supply device connected in parallel.

[0033] Specifically, in the conventional hydrogen storage process, the solid-state hydrogen storage tank is usually made of aluminum alloy. During the heating and activation process, the outer wall of the aluminum alloy tank will come into direct contact with water, which will cause oxidation and blackening, and will also affect the activation efficiency of the solid-state hydrogen storage tank. In order to solve the above problems, the present application includes an activation box 1, which is used as a structural carrier for activating the solid-state hydrogen storage tank. The activation box 1 is penetrated with a plurality of station barrel tubes 2 along the thickness direction, which are used to form a storage activation station of the solid-state hydrogen storage tank. The axial outer wall of each station barrel tube 2 is flush with the end face of the activation box 1 on the same side and is sealed. Gaps are left between adjacent station barrel tubes 2, and between the radial outer wall of the station barrel tube 2 and the inner wall of the activation box 1 facing the radial outer wall of the station barrel tube 2, and are connected to form a heat exchange inner cavity 8, which is used to form a liquid cooling or heating flow channel for the station barrel tube 2. The bottom outer wall of the activation box 1 is provided with an inlet 3, and the top outer wall of the activation box 1 is provided with a The outlet 4, the inlet 3 and the outlet 4 are connected with a hot and cold water machine, wherein the hot and cold water machine is used to provide refrigeration or heating power for the heat exchange cavity 8, thereby realizing heating activation and cooling hydrogen storage. The heat exchange cavity 8 realizes all-round cooling of multiple station barrel tubes 2 inside the heat exchange cavity 8 through the bottom-in and top-out drainage structure, thereby realizing all-round cooling of the station barrel tube 2. The station barrel tube 2 is a tubular structure with an axial through hole, which is used to realize the positioning and placement of the solid-state hydrogen storage tank. A solid-state hydrogen storage tank is placed in each station barrel tube 2. The solid-state hydrogen storage tank is connected to a parallel vacuum device and a hydrogen supply device, so that in the process of hydrogen storage or dehydrogenation, the solid-state hydrogen storage tank can obtain a comprehensive and efficient activation effect. Through the above structure, direct contact between the solid-state hydrogen storage tank and water is avoided, and oxidation and discoloration of the solid-state hydrogen storage tank are prevented. In addition, by setting a plurality of activation stations, while ensuring good thermal conductivity of the solid-state hydrogen storage tank, the activation efficiency of the solid-state hydrogen storage tank is enhanced.

[0034] In some preferred embodiments, the left and right inner walls of the activation box 1 are alternately connected with a plurality of guide plates 9 in sequence along the height direction, and a guide gap is left between the free end of the guide plate 9 and the inner wall of the activation box on the same side.

[0035] Specifically, Figure 4 As shown, in order to further enhance the heating uniformity of the heat exchange cavity 8, the left and right inner walls of the activation box 1 are staggered in sequence along the height direction with multiple guide plates 9, and a guide gap is left between the free end of the guide plate 9 and the inner wall of the activation box on the same side. The multiple guide plates 9 play a guiding role in the heat exchange cavity 8, achieving more sufficient and comprehensive guide heating or cooling, and then realizing efficient activation of the solid hydrogen storage tank. The structure of the guide gap allows the heat in the heat exchange cavity 8 to flow gradually and progressively, so that the station barrel tube 2 in the heat exchange cavity is heated more evenly and fully, avoiding uneven heating of the solid hydrogen storage tank due to rapid flow of heat or incomplete flow space. Among them, the staggered connection structure of the guide plate 9 and the inner wall of the activation box 1 also further ensures the sufficient guide effect of the guide plate 9 on the heat, making the heat flow path more uniform and complete, and making the station barrel tube 2 more fully and evenly heated, thereby ensuring the good thermal conductivity of the solid hydrogen storage tank while enhancing the activation efficiency of the solid hydrogen storage tank.

[0036] In some preferred embodiments, the width of the guide slit is smaller than the outer diameter of the station barrel tube 2 .

[0037] Specifically, in order to ensure that each station barrel tube 2 can obtain a sufficient and uniform heating effect, the width of the guide seam is smaller than the outer diameter of the station barrel tube 2. This arrangement allows heat to flow in the heat exchange inner cavity 8. It can always perform complete immersion heating on the station barrel tube 2 between adjacent guide plates 9, thereby preventing the station barrel tube 2 located at the guide seam from being unevenly heated or having insufficient heating time due to the guide seam being too large or the flow rate being too fast. As a result, the heat flow in the heat exchange inner cavity 8 is optimized and fully covered in terms of path under the action of the guide plate 9 and the guide seam, so that each station barrel tube 2 can obtain a sufficient and comprehensive cooling or heating effect, thereby more efficiently realizing the activation of the solid-state hydrogen storage tank while ensuring good thermal conductivity of the solid-state hydrogen storage tank.

[0038] In some preferred embodiments, a row of station barrel tubes 2 is arranged between adjacent guide plates 9 .

[0039] Specifically, in order to optimize the spatial layout of the work station barrel tubes 2 and improve the heating effect of the work station barrel tubes 2, a row of work station barrel tubes 2 is arranged between adjacent guide plates 9, and a flow channel is formed between adjacent guide plates 9, and multiple flow channels connected end to end are formed between multiple adjacent guide plates 9. By arranging a row of work station barrel tubes 2 between adjacent guide plates 9, the space optimization of the flow channel in the heat exchange inner cavity 8 is achieved, so that the height difference between adjacent guide plates 9 and the outer wall diameter of the work station barrel tube 2 are maintained within a reasonable range, that is, only one row of work station barrel tubes 2 can be accommodated between adjacent guide plates 9, and the height difference cannot accommodate the height of two stacked work station barrel tubes 2 or more stacked work station barrel tubes 2, thereby avoiding the flow channel space being too large to cause the work station barrel tube 2 to heat up too slowly, thereby improving the heating efficiency of the work station barrel tube 2 and enhancing the activation efficiency of the solid-state hydrogen storage tank. In addition, through the structure of the guide plate 9, the heat flow is guided and a row of workstation barrel tubes 2 between adjacent guide plates 9 are immersed in heating or cooling, so that the heat is fully utilized and the uneven heat caused by too many or too few workstation barrel tubes 2 is prevented, so that the solid-state hydrogen storage tank can obtain sufficient and comprehensive heating or cooling, thereby obtaining a more efficient activation effect.

[0040] In some preferred embodiments, a plurality of station barrel tubes 2 are arranged in a triangular array or a rectangular array through the activation box 1 .

[0041] Specifically, Figure 1 and Figure 3 As shown, a plurality of station barrel tubes 2 are arranged in a triangular array or a rectangular array through the activation box 1, thereby optimizing the position of the station barrel tubes 2, making the activation station for accommodating the solid hydrogen storage tank have a higher space utilization rate, and ensuring a good heating and activation effect. Among them, the setting method of the triangular array makes the center of gravity of the overall structure biased toward the geometric center position of the activation box 1, thereby ensuring the stable support of the activation box 1 for other components during the installation process as a carrier, preventing shaking or tilting during the transportation or loading and unloading of the solid hydrogen storage tank, and ensuring safety during operation. The setting method of the rectangular array guarantees the density of the activation station to a greater extent, ensuring that the plurality of station barrel tubes 2 can be arranged in the activation box 1 in a manner with high space utilization, thereby achieving a simultaneous heating and activation effect for multiple solid hydrogen storage tanks, thereby improving the activation efficiency of the solid hydrogen storage tanks.

[0042] In some preferred embodiments, the diameter of the axial through hole matches the outer diameter of the solid-state hydrogen storage tank.

[0043] Specifically, in order to facilitate the positioning and placement of the solid-state hydrogen storage tank in the work station barrel tube 2, in this embodiment, the diameter of the axial through hole is adapted to the outer diameter of the solid-state hydrogen storage tank, thereby increasing the contact area between the work station barrel tube 2 and the solid-state hydrogen storage tank, thereby achieving sufficient contact between the work station barrel tube 2 and the solid-state hydrogen storage tank, ensuring that the solid-state hydrogen storage tank obtains sufficient and uniform heating and activation effect.

[0044] In some preferred embodiments, a door cover 7 is rotatably provided on the rear end face of the activation box 1, and the size of the door cover 7 is adapted to the size of the rear end face of the activation box 1. When closed, the door cover 7 forms a sealed abutment with the rear end face of the activation box 1.

[0045] Specifically, Figure 2 As shown, in the actual hydrogen storage process, the solid-state hydrogen storage tank needs to be carried out certain handling or loading and unloading operations. Therefore, in order to facilitate various operations of the solid-state hydrogen storage tank, the rear end face of the activation box 1 is rotatably provided with a door cover 7. The size of the door cover 7 is adapted to the size of the rear end face of the activation box 1. The door cover 7 forms a sealed abutment with the rear end face of the activation box 1 when closed. By using the door cover 7 as a connecting structure with sealing and switching functions, the convenience of the solid-state hydrogen storage tank in daily operation is enhanced. At the same time, when the door cover 7 is closed, it forms a sealed abutment with the rear end face of the activation box 1, thereby achieving a sealing effect during the hydrogen storage process, ensuring that the solid-state hydrogen storage tank obtains sufficient and uniform heating and activation effect, and avoiding a reduction in the heating and activation efficiency of the solid-state hydrogen storage tank due to heat loss.

[0046] In some preferred embodiments, a silicone rubber pad 6 is provided on the inner wall edge of the front end of the station barrel tube 2 , and a silicone rubber pad 6 is provided on the inner surface edge of the door cover 7 .

[0047] Specifically, Figure 1 and Figure 3 As shown, in order to further enhance the heat activation effect of the solid-state hydrogen storage tank and avoid heat loss between the work station barrel tube 2 and the solid-state hydrogen storage tank, a silicone rubber pad 6 is provided at the edge of the front inner wall of the work station barrel tube 2 to achieve a sealed connection between the front of the work station barrel tube 2 and the front of the solid-state hydrogen storage tank, and a silicone rubber pad 6 is provided on the edge of the inner surface of the door cover 7 to achieve a sealed connection between the rear of the activation box 1 and the door cover 7, thereby sealing the work station barrel tube 2 and the solid-state hydrogen storage tank inside the activation box 1. Through the above two structural settings, heat loss between the work station barrel tube 2 and the solid-state hydrogen storage tank is avoided, thereby enhancing the heat transfer efficiency between the work station barrel tube 2 and the solid-state hydrogen storage tank, and then enhancing the heating activation effect of the solid-state hydrogen storage tank.

[0048] In some preferred embodiments, the station barrel tube 2 is made of aluminum or copper.

[0049] Specifically, in order to ensure the good thermal conductivity of the work station barrel tube 2, the work station barrel tube 2 is made of aluminum or copper. In the actual hydrogen storage process, the work station barrel tube 2 is set to be made of aluminum or copper, which can effectively ensure the good thermal conductivity of the work station barrel tube 2 during the heat transfer process, thereby transferring the heat in the heat exchange inner cavity 8 to the solid-state hydrogen storage tank with higher efficiency, thereby enabling the solid-state hydrogen storage tank to obtain a better heating activation effect. At the same time, in a structural layout with multiple work station barrel tubes 2, the work station barrel tube 2 made of aluminum or copper also has a relatively low cost, which is convenient for reducing the cost and implementation difficulty of the overall structure while ensuring good thermal conductivity.

[0050] In some preferred embodiments, each solid-state hydrogen storage tank is connected to the vacuum device via a vacuum valve, and each solid-state hydrogen storage tank is connected to the hydrogen supply device via a hydrogen supply valve.

[0051] Specifically, in order to make the hydrogen storage and hydrogen release operations of the solid-state hydrogen storage tank more convenient, each solid-state hydrogen storage tank is connected to the vacuum device through a vacuum valve, and each solid-state hydrogen storage tank is connected to the hydrogen supply device through a hydrogen supply valve. Among them, the vacuum device is a vacuum pump group connected to the solid-state hydrogen storage tank, which is used to evacuate and ensure the purity of hydrogen. Each solid-state hydrogen storage tank is connected to the vacuum pump group through a corresponding vacuum valve to achieve independent control of each solid-state hydrogen storage tank, and enhance the convenience and flexible control of the solid-state hydrogen storage tank during the vacuum process; the hydrogen supply device is a hydrogen supply system connected to the solid-state hydrogen storage tank, and each solid-state hydrogen storage tank is connected to the hydrogen supply system through a hydrogen supply valve to achieve independent control of each solid-state hydrogen storage tank, and enhance the convenience and flexible control of the solid-state hydrogen storage tank during the hydrogen supply process. Among them, the hydrogen source of the hydrogen supply system can be selected from but not limited to hydrogen cylinders, hydrogen cylinder groups or water electrolysis hydrogen production systems, so as to select the corresponding hydrogen supply system according to the actual hydrogen supply demand, thereby ensuring the activation efficiency of the solid-state hydrogen storage tank.

[0052] In some preferred embodiments, a base 5 is connected to the bottom of the activation box 1 .

[0053] Specifically, by connecting the base 5 to the bottom of the activation box 1, a stable support is provided for the activation box 1, which is convenient for its transportation or other operations. At the same time, the activation box 1 is separated from the ground to prevent the ground from affecting the heating activation operation in the activation box 1, thereby providing auxiliary enhancement for improving the activation production efficiency of the solid-state hydrogen storage tank.

[0054] Through the above technical scheme, the multi-station solid-state hydrogen storage tank activation device provided in the present application includes an activation box 1, which is used as a structural carrier for activating the solid-state hydrogen storage tank.

The axial outer wall of each station barrel tube 2 is flush with the end face of the activation box 1 located on the same side and is sealed and connected. Gaps are left between adjacent station barrel tubes 2, and between the radial outer wall of the station barrel tube 2 and the inner wall of the activation box 1 facing the radial outer wall of the station barrel tube 2, and are connected to form a heat exchange inner cavity 8, which is used to form a liquid cooling or heating flow channel for the station barrel tube 2. The bottom outer wall of the activation box 1 is provided with an inlet 3, and the top outer wall of the activation box 1 is provided with an outlet 4. The inlet 3 and the outlet 4 is connected with a hot and cold water machine, which is used to provide cooling or heating power for the heat exchange cavity 8, and realizes all-round cooling of the heat exchange cavity 8 through the bottom-in and top-out drainage method, thereby realizing all-round cooling of the station barrel tube 2. The station barrel tube 2 is a tubular structure with an axial through hole, which is used to realize the positioning and placement of the solid-state hydrogen storage tank. A solid-state hydrogen storage tank is correspondingly placed in each station barrel tube 2. The solid-state hydrogen storage tank is connected to a parallel vacuum device and a hydrogen supply device, so that in the process of hydrogen storage or hydrogen release, the solid-state hydrogen storage tank can obtain a comprehensive and efficient activation effect. Through the above structure, direct contact between the solid-state hydrogen storage tank and water is avoided, and oxidation and discoloration of the solid-state hydrogen storage tank are prevented. By setting a plurality of activation stations, while ensuring good thermal conductivity of the solid-state hydrogen storage tank, the solid-state hydrogen storage tank is enhanced. Activation efficiency of the hydrogen storage tank; the left and right inner walls of the activation box 1 are staggered with multiple guide plates 9 in sequence along the height direction, and a guide gap is left between the free end of the guide plate 9 and the inner wall of the activation box on the same side. The multiple guide plates 9 play a guiding role in the heat exchange cavity 8, achieving more sufficient and comprehensive guide heating or cooling, and then achieving efficient activation of the solid-state hydrogen storage tank. The structure of the guide gap also further makes the heat flow in the heat exchange cavity 8 more uniform, avoiding uneven heating of the solid-state hydrogen storage tank due to the rapid flow of heat, thereby ensuring good thermal conductivity of the solid-state hydrogen storage tank while enhancing the activation efficiency of the solid-state hydrogen storage tank; the width of the guide gap is smaller than the outer diameter of the station barrel tube 2, so that the heat flow in the heat exchange cavity 8 is under the action of the guide plate 9 Optimization and full coverage of the path are achieved, so that each station barrel tube 2 can obtain a full and comprehensive cooling or heating effect, thereby ensuring good thermal conductivity of the solid-state hydrogen storage tank while more efficiently realizing the activation of the solid-state hydrogen storage tank; a row of station barrel tubes 2 is arranged between adjacent guide plates 9, so that the position layout of the station barrel tubes 2 between adjacent guide plates 9 is more reasonable, and the structure of the guide plate 9 is used to guide the flow of heat, and immerse the row of station barrel tubes 2 between adjacent guide plates 9 for heating or cooling, so as to fully utilize the heat and prevent the occurrence of uneven heat due to too many or too few station barrel tubes 2, so that the solid-state hydrogen storage tank can obtain full and comprehensive heating or cooling, and thus obtain a more efficient activation effect.
