Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen storage, and particularly relates to an integrated framework for solid-state hydrogen storage, hydrogen charging and hydrogen discharging. Background Art

[0002] Currently, hydrogen energy, as an efficient and clean energy form, is gradually attracting wide attention. However, the storage and transportation of hydrogen energy have always been the key issues restricting its commercial application. In this context, solid-state hydrogen storage technology, with its high hydrogen storage density and reliable safety performance, has become one of the most effective ways to break through the bottleneck of hydrogen storage and transportation. Solid-state hydrogen storage technology refers to the physical or chemical adsorption of hydrogen by solid materials to achieve hydrogen storage. Compared with traditional gaseous storage technologies, solid-state hydrogen storage technology has significant advantages. First of all, the hydrogen storage density of solid-state hydrogen storage is much higher than that of gaseous storage, which means that under the same volume, solid-state hydrogen storage can store more hydrogen, thus improving the storage efficiency. Secondly, the working pressure of solid-state hydrogen storage is low, reducing the safety risks during storage and transportation. Finally, solid-state hydrogen storage materials usually have good stability and safety, which can ensure the long-term safe storage of hydrogen. Among them, metal hydride hydrogen storage is currently the most promising and rapidly developing solid-state hydrogen storage method. When different enterprises and research institutions layout solid-state hydrogen storage business, the development paths they choose are also different, including various technical routes such as magnesium-based hydrogen storage materials, titanium-based hydrogen storage materials, and rare-earth-based hydrogen storage materials.

[0003] Currently, magnesium-based materials are usually used under high-temperature conditions (above 200°C), while titanium-based / rare-earth hydrogen storage materials have good hydrogen absorption and desorption performance and stability at room temperature. Due to the need for pressure resistance, most current solid-state hydrogen storage is still in the form of bottled. And titanium-based / rare-earth hydrogen storage materials usually still have heat generation / absorption phenomena during hydrogen charging / discharging. How to evenly transfer heat through the bottle body or input it is still a difficult point in the application of solid-state metal hydrogen storage. Although most solutions still use water bath cooling or water bath heating treatment, this method is more used in indoor or well-equipped scenarios, and the hydrogen storage bottle can only be taken up and down in the water bath container, and cannot be pulled out horizontally. In addition, the existing integrated frameworks for solid-state hydrogen storage on the market are relatively simple in air duct structure, and the actual test verification effect is not ideal. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an integrated framework for solid-state hydrogen storage, hydrogen charging and hydrogen discharging. Through excellent structural design, it cools and heats the solid-state metal hydrogen storage bottle evenly and stably in the ways of air cooling and hot air, so as to meet the temperature requirements of the solid-state metal hydrogen storage bottle for hydrogen charging and discharging.

[0021] The present invention will be described in detail below through specific embodiments, but the protection scope of the present invention is not limited. Unless otherwise specified, the experimental methods adopted in the present invention are all conventional methods, and the experimental equipment, materials, reagents, etc. used can be obtained from commercial channels.

[0022] Embodiment 1

[0023] An integrated framework for solid-state hydrogen storage for hydrogen charging and discharging ( Figure 1 ), comprising:

[0024] The main framework 1 of solid-state hydrogen storage, the inside of the main framework 1 of solid-state hydrogen storage is a square single slot 4 of solid-state hydrogen storage bottle for placing the solid-state hydrogen storage bottle 5;

[0025] The finned radiator 2 is divided into an air duct 7 and a finned area 8. The finned area 8 is connected to the main framework 1 of solid-state hydrogen storage, and the air duct 7 is connected to the air duct 7. The air duct 7 is used to evenly distribute the air pressure so that the air flows evenly over the fin surface;

[0026] The fan 3 is connected to the air duct 7 of the finned radiator 2 and serves as an air inlet.

[0027] The material of the main framework 1 of solid-state hydrogen storage is metal.

[0028] One end of the single slot 4 of solid-state hydrogen storage bottle ( Figure 2 ) close to the finned radiator 2 is provided with a cross baffle 99 for restricting the solid-state hydrogen storage bottle 5 from sliding too deep. A wind baffle 10 is provided in the middle of the single slot 4 of solid-state hydrogen storage bottle. A hinge 11 is provided at the connection between the upper end of the wind baffle 10 and the single slot 4 of solid-state hydrogen storage bottle, and a support 12 of wind baffle is provided at the connection between the lower end of the wind baffle 10 and the single slot 4 of solid-state hydrogen storage bottle for preventing the fan 3 air from only flowing through here when the solid-state hydrogen storage bottle 5 is removed, affecting the heat dissipation or heat absorption of other solid-state hydrogen storage bottles 5.

[0029] Water inlets 6 are provided at the upper and lower ends on the side of the finned radiator 2. The lower water inlet 6 is used for hot water outlet and cold water inlet, and the lower water inlet 6 is used for hot water inlet and cold water outlet.

[0030] The position of the fan 3 corresponds to the single slots of four solid-state hydrogen storage bottles.

[0031] like Figure 3 The solid-state hydrogen storage bottle 5 that stores hydrogen in titanium / rare earth needs to dissipate heat when filling hydrogen. Therefore, when filling hydrogen, cooling water is introduced into the fin radiator 2, and the fan is turned on. The temperature of the air is reduced after passing through the fins, and the air with lower temperature takes away the heat of the solid-state hydrogen storage bottle 5 after flowing through the solid-state hydrogen storage bottle 5.

[0032] like Figure 4 The solid-state hydrogen storage bottle using titanium / rare earth to store hydrogen needs to be heated when discharging hydrogen. Therefore, when discharging hydrogen, hot water (such as residual hot water of the fuel cell) is introduced into the fin radiator 2. Then the fan 3 is turned on, and the temperature of the air is increased after passing through the fins. The higher temperature air transfers the heat into the solid-state hydrogen storage bottle 5 after passing through the solid-state hydrogen storage bottle 5 to realize the heating function.

[0033] like Figure 5 When a solid hydrogen storage bottle 5 is removed, the hinge 11 with the wind shield 10 blocks the wind from the fan 3 under the action of gravity, so that the wind is redirected and flows through other slots with solid hydrogen storage bottles 5 to avoid wind loss.

[0034] The above-described embodiments are only preferred embodiments of the present invention, but not all feasible embodiments of the present invention. For those skilled in the art, any obvious changes made thereto without departing from the principles and spirit of the present invention should be considered to be included in the scope of protection of the claims of the present invention.
