Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage equipment, and in particular to a vertical partition-type solid-state hydrogen storage equipment. Background Art

[0002] Hydrogen energy is hailed as the ultimate energy source of the 21st century. Hydrogen storage technology lies in the midstream of hydrogen energy research, development, and utilization, with increasing hydrogen storage density becoming a key research area. At the current technological stage, hydrogen storage is primarily categorized into high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, organic liquid hydrogen storage, and solid-state hydrogen storage. The application of these hydrogen storage methods at the societal level is also becoming increasingly mature. Solid-state metal hydrogen storage utilizes solid metal materials placed within its device to complete hydrogen storage tasks. The principle is to combine the material with hydrogen to form a hydride, thereby storing hydrogen within the alloy. This hydrogen storage material possesses unique properties. Under specific temperature and hydrogen pressure conditions, an exothermic reaction occurs, absorbing hydrogen to form a metal hydride. When heated, an endothermic reaction occurs, releasing the previously absorbed hydrogen.

[0003] For solid-state hydrogen storage, it is necessary to comprehensively consider the hydrogen absorption and desorption characteristics of the hydrogen storage material, temperature conditions, pressure conditions, heat exchange type, and application scenarios. Optimizing the structural conditions of the equipment is very important for saving energy utilization. The choice of efficient heat exchange method to match high hydrogen storage density materials has become an essential consideration. High-temperature steam has the advantages of high heat transfer efficiency, clean and environmental protection, safety and reliability.

[0045] The output pipe 1 81 and the output pipe 2 82 are respectively connected to the bottom of the steam layer lower wall 162 at the two-dimensional center of four adjacent solid hydrogen storage tanks 17 .

[0046] In the present invention, a plurality of fixing grooves 151 are uniformly arranged on the surface of the base 15. A solid hydrogen storage tank 17 is disposed within the fixing grooves 151.

[0047] Example: When used, it includes the following three steps:

[0048] Step 1: In-pipe transportation process based on high-temperature steam;

[0049] Open the steam output valve 10, the six auxiliary steam valves 2, and the steam input valve 21 to ensure that the pressure in the steam layer 16 and the steam flow area within the solid-state hydrogen storage tank 17 is balanced with atmospheric pressure. After opening the steam input valve 21, the high-temperature steam flows through the main trunk of the high-temperature steam delivery pipe 1 and is then diverted to the six auxiliary steam pipes 3 and into the inner tube 25 of the solid-state hydrogen storage tank 17. The steam flows through the center of the solid-state hydrogen storage tank 17, passes through the diverter cone 176 and the partition layer 178, and simultaneously heats the inner liner 177 of the solid-state hydrogen storage tank 17 internally and externally before entering the steam layer 16. It is then transported to the steam output port 11 through output pipe 1 81 and output pipe 2 82 located at the bottom of the steam layer 16. Output pipe 1 81 and output pipe 2 82 are respectively connected to the bottom of the steam layer lower wall 162 at the two-dimensional center of four adjacent solid-state hydrogen storage tanks 17.

[0050] Step 2: Heating process based on high-temperature steam;

[0051] The high-temperature steam passes through the inner tube 25 of the solid-state hydrogen storage tank 17 to heat the solid-state hydrogen storage material 26 from the center to the outside, and the heat transfer through the spiral fins 27 makes the solid-state hydrogen storage material 26 heated more evenly; the high-temperature steam flows through the diverter cone 176 inside the inner wall 172 of the tank body and is geometrically constrained and flows toward the partition layer 178 under the push of the subsequent high-temperature steam, heating the inner liner 177 in the partition layer 178, so that the solid-state hydrogen storage material 26 is heated from the outside to the inside; the high-temperature steam passes through the partition layer 178 and merges into the steam layer 16.

[0052] Step 3: hydrogen-based transportation process;

[0053] Open the hydrogen storage tank valve 24, hydrogen pipe valve 13, and hydrogen charging and discharging main valve 6 to balance the pressure in the hydrogen flow area. Hydrogen generated by the solid hydrogen storage material 26 is discharged from the solid hydrogen storage tank 17 through the hydrogen charging and discharging port 29 and collected in the hydrogen pipe 7, where it is discharged under the control of the hydrogen charging and discharging main valve 6. The hydrogen discharging process is similarly applicable to the hydrogen charging process of the solid hydrogen storage material 26 heated by high-temperature steam. The total amount of hydrogen absorbed and discharged by the equipment can be controlled by adjusting any one or more valves associated with the solid hydrogen storage tank 17.

[0054] The steam pipe joint 18 and the hydrogen storage tank cover 171 are inlaid and fixed by bolts, and a metal sealing ring 28 is provided at the inlaid contact part; the inner tube 25 of the solid hydrogen storage tank 17 is inlaid with the hydrogen storage tank cover 171 and the cover insulation layer 179, and a metal sealing ring 28 is provided at the inlaid contact part, which can greatly ensure that high-temperature steam and hydrogen will not leak.

[0055] The spiral fin 27 has a sleeve with internal threads 272 at both ends of the sleeve. The spiral fin 27 is put on the inner tube 25 and fixed by rotating with the threads at both ends; the blade 271 is spiral-shaped, and when the solid hydrogen storage material 26 is added, the spiral structure of the blade 271 is used to scratch to the bottom of the inner tank 177.

[0056] The base 15 is provided with a fixing groove 151 whose size matches the outer wall 174 of the solid-state hydrogen storage tank 17, which is used to fix the horizontal and vertical positions of the solid-state hydrogen storage tank 17. The four columns 19 are used to support the steam layer 16 and other components. The top of the column 19 is provided with a steam layer limiter 191 for fixing the steam layer 16 to ensure the stability of the steam layer 16.
