Specific implementation method one:

[0055] like Figure 1 and Figure 2 As shown, a solid metal hydrogen storage device includes a hydrogen storage tank 1, which includes an inner tank body 102, wherein the inner tank body 102 is provided with a plurality of storage bins 104 separated by partitions 105 and partition plates 110, and the storage bins 104 are provided with a plurality of heat dissipation fins; a plurality of flexible buffer materials 106 for buffering protection are provided between the inner tank body 102 and the partition plates 105 and the partition plates 110.

[0056] The working principle and beneficial effects of this embodiment are as follows: the storage bin 104 stores alloy powder, which is one or more of rare earth AB 5 type, titanium AB 2 type, AB type and titanium-vanadium BCC solid solution hydrogen storage alloys;

[0057] The partition plate 105 is slidably connected inside the inner tank body 102 .

[0058] Preferably, an air duct 103 is provided in the inner tank body 102 , and the air duct 103 passes through the storage bin 104 and the partition 105 , one end of the air duct 103 is fixedly connected to the inner wall of the inner tank body 102 , and the other end of the air duct 103 passes through the inner tank body 102 .

[0059] Preferably, the air guide tube 103 is a sintered body of copper powder or stainless steel powder, and the filtering accuracy does not exceed 50 μm. The function of the air guide tube is to make the hydrogen evenly distributed in the inner tank 102, ensure that the hydrogen is fully in contact with the hydrogen storage alloy powder, and improve the uniformity of hydrogen charging and discharging of the hydrogen storage alloy powder;

[0060] Preferably, an outer shell 101 is disposed outside the inner tank body 102, and the outer shell 101 and the inner tank body 102 are fixedly connected via a fixing block 107;

[0061] The outer shell 101 is provided with at least one set of coolant inlet and outlet 109;

[0062] Preferably, an air inlet 108 is provided on the outer shell 101, and the air inlet 108 is located at the place where the air guide pipe 103 passes through the inner tank body 102, and one end of the air guide pipe 103 passing through the inner tank body 102 is located in the air inlet 108;

[0063] Preferably, a hydrogen filter is provided at the air inlet 108. The hydrogen filter is a sintered body of copper powder or stainless steel powder, and the filtering accuracy does not exceed 5 μm, so as to prevent the extremely fine particles generated during the absorption and release of hydrogen by the hydrogen storage alloy powder from entering the gas transmission pipeline along with the hydrogen.

[0064] A plurality of partitions 105 are designed in the inner tank body 102, and a storage bin 104 is formed between each partition 105. The storage bin 104 stores alloy powder. A flexible buffer material 106 is arranged on the outer side of the partition 105 of each storage bin. The characteristics of the flexible buffer material 106 are used to offset the stress generated by the expansion of the hydrogen storage alloy due to hydrogen absorption, which can effectively reduce the damage of the hydrogen storage alloy expansion to the inner tank body 102. At the same time, the compression effect of the flexible buffer material 106 on the solid alloy powder can be used to compact the solid hydrogen in each storage bin 104, thereby ensuring that the solid hydrogen storage powder will not move with the movement of the inner tank body 102 during transportation, preventing the migration of the hydrogen storage powder, and thus improving the transportation safety of solid hydrogen;

[0065] An outer shell 101 is arranged outside the inner tank 102, and a coolant is poured between the outer shell 101 and the inner tank 102, so that the outer wall of the inner tank 102 is in contact with the coolant, thereby ensuring uniform heat dissipation of the inner tank 102 and the efficiency of solid-state hydrogen storage. The alloy powder in the storage bin reacts with hydrogen and releases a large amount of heat while absorbing hydrogen.

[0066] The positions of the coolant inlet and outlet 109 are specifically selected according to the connection status of the storage tank body, which ensures the practicability of the device; at the same time, it solves the problems of poor heat exchange performance, poor thermal conductivity and short service life of the solid hydrogen storage device. Specific implementation method 2:

[0068] like Figure 1 and Figure 2 As shown, a solid metal hydrogen storage device, the flexible buffer material 106 is a spring or an elastic porous metal material;

[0069] The heat dissipation fin is one of an aluminum plate, a copper plate and a metal mesh.

[0070] The working principle and beneficial effects of this embodiment are as follows: adding heat dissipation fins (thin aluminum plates, copper plates or corresponding metal meshes) to the solid-state hydrogen storage device to increase the thermal conductivity of the hydrogen storage device, and regulating and controlling the spacing and number of heat dissipation fins;

[0071] Flexible buffer materials (springs, highly elastic porous metal materials, etc.) can, on the one hand, prevent the solid hydrogen storage alloy powder from absorbing hydrogen and expanding, thereby damaging the hydrogen storage tank. At the same time, they can compress the solid alloy powder to reduce the porosity of the alloy powder and increase the thermal conductivity of the hydrogen storage device. Specific implementation method three:

[0073] like Figure 1 , Figure 2 and Fig.18 As shown, a solid metal hydrogen storage device, the partition 105 is slidably connected in the inner tank body 102; the inner tank body 102 is provided with an air guide tube 103 that passes through the storage bin 104, the partition 105 and the partition plate 110, one end of the air guide tube 103 is fixedly connected to the inner wall of the inner tank body 102, and the other end of the air guide tube 103 passes through the inner tank body 102;

[0074] The inner tank body 102 is wrapped with an outer tank body 101; a cooling channel is provided between the inner tank body 102 and the outer tank body 101; the outer tank body 101 and the inner tank body 102 are fixedly connected by a fixing block 107;

[0075] The outer shell 101 is provided with at least one set of coolant inlet and outlet 109;

[0076] The outer shell 101 is provided with an air inlet 108, which is located at the place where the air pipe 103 passes through the inner tank 102, and one end of the air pipe 103 passing through the inner tank 102 is located inside the air inlet 108.

[0077] The working principle and beneficial effects of this embodiment are as follows: the existence of the outer shell 101 facilitates the protection of the inner tank body 102 and facilitates heat dissipation; the outer shell 101 is arranged outside the inner tank body 102, and coolant is poured between the outer shell 101 and the inner tank body 102, so that the outer wall of the inner tank body 102 is in contact with the coolant, ensuring uniform heat dissipation of the inner tank body 102 and ensuring the efficiency of solid-state hydrogen storage. The alloy powder in the storage bin reacts with hydrogen and releases a large amount of heat while absorbing hydrogen;

[0078] Regarding the hydrogen charging and dehydration rate, after direct powder loading and activation, the D50 particle size is about 10μm~45μm, and the thermal conductivity is ~0.1W / (m·K), while the compacted thermal conductivity is 3~10W / (m·K), which is dozens of times different. The hydrogen storage material itself is basically saturated in about 5 minutes. The fundamental reason for the slow hydrogen absorption and dehydration rate in actual testing is the poor thermal conductivity of the material and a large amount of heat accumulation;

[0079] Heat transfer data for reactor beds mainly include λeff and hw. Fig.18 . Although the effective thermal conductivity of pure powder or particle beds is very low, on the order of 0.1 to 1 W / m·K, significant improvements can be obtained even at high gas pressures, e.g., hydrogen pressures in metal hydrides, by the measures described in Section 2. Of particular interest are anisotropic porous graphite matrices, which yield effective thermal conductivities λeff of the order of 5 to 30 W / m·K in the radial direction and <1 W / m·K in the axial direction. They have been used together with ammoniated salts. Consolidation of activated carbon AC and zeolite NaX, 4A beds to form porous blocks and inclusion of high-porosity metal foams Ni, Cu as heat transfer matrices yields effective thermal conductivities λeff of the order of 5 to 30 W / m·K. With regard to metal hydrides, two main techniques have shown good results. One solid-state metal hydrogen storage device is a metal foam with high porosity in the metal matrix and an internal fin-like structure; another solid-state metal hydrogen storage device is a mixture of metal hydride powder and aluminum powder and cold pressed into small compacts, with or without subsequent sintering. Depending on the amount of Al powder used, very high λeff can be obtained, for example, for 31wt% Al, λeff≈23W / m·K.

[0080] In addition to the thermal conductivity itself, the contact thermal resistance of the bed wall must also be observed. Values ​​up to 1000 W / m·K can be obtained for anisotropic graphite matrices; similar data have been determined for Al foam matrices that have been tapped to fit the tube wall well. Higher values ​​can be obtained when a metal matrix can be welded to the reactor bed wall. The thermal resistance of the bed wall is generally negligible, even for stainless steel wall materials with λ = 17 W / m·K. Specific implementation method four:

[0082] like Figure 1 -and Fig.17 As shown, a solid metal hydrogen storage device, the inner tank body 102 is wrapped and installed with the outer tank body 101 by a tank shell packaging device;

[0083] The can shell packaging device includes an operating frame 2, and a stacking conveyor 3 is arranged at one end of the operating frame 2 to transport multiple inner can bodies 102 to the divider 4. The inner can bodies 102 are separated by the divider 4 and transported to the spraying conveyor 5 for transportation and spraying. The spraying conveyor 5 transports the sprayed inner can bodies 102 to the clamping outer rolling table 9. The clamping outer rolling table 9 rolls the metal thin shell unrolled by the unwinder 6 and the unwinding table 7 on the inner can body 102 to form an outer shell 101. The rolled inner can body 102 with the outer shell 101 is transported out through the tail conveyor 8 for welding; multiple sensors and power supplies are arranged on the operating frame 2.

[0084] The working principle and beneficial effects of this embodiment are as follows: the inner tank body 102 to be wrapped and installed with the outer shell 101 is added to the stacking conveyor 3 of the operating frame 2 for transportation, and the direction and interval of the transported inner tank body 102 are stably adjusted through the separator 4, so as to facilitate the transportation of multiple inner tank bodies 102 processed simultaneously in a stable state and direction interval, and then the inner tank body 102 is added to the spraying conveyor 5, and is transported by flipping in the spraying conveyor 5, so as to realize the full-scale spraying of the surface of the inner tank body 102, and the anti-corrosion, anti-rust and wear-resistant coatings are applied to the surface of the hydrogen storage tank by spraying, brushing and other methods to provide an additional protective layer; the special coating technology can also improve the reflectivity or anti-ultraviolet performance of the surface;

[0085] The sprayed inner tank body 102 is transported to the clamping outer winding table 9 by the spraying conveyor 5, and the inner tank body 102 is clamped and lifted by the clamping outer winding table 9 to fit the metal shell unwound by the unwinder 6 onto the unwinding table 7, and the clamped and lifted inner tank body 102 is driven to rotate by the clamping outer winding table 9, so that the sticky metal shell is rolled up on the surface of the inner tank body 102, and then the unwinding table 7 is cut off and the clamping outer winding table 9 is used to reset the inner tank body 102, and finally the metal shell is transported out by the tail conveyor 8 for welding and sealing, so as to complete the wrapping and installation of the outer shell 101 of the inner tank body 102 to form a solid metal hydrogen storage device; according to different needs, the outer shell 101 of different materials and styles can be selected for use, so as to protect the inner tank body 102 and dissipate heat at the same time.

[0088] The separator 4 includes a support slide 46, which is fixed on the operating frame 2. The separation driver 41 drives the separation transport plate 42 to rotate through an eccentric drive shaft 47. The eccentric drive shaft 47 is connected to a rotating roller 43 through a fixed seat. The rotating roller 43 is connected to a separation receiving roller 44 through a transmission belt.

[0089] Both the separation receiving roller 44 and the rotating roller 43 are provided with semicircular arc grooves for transporting the inner tank body 102 .

[0090] The working principle and beneficial effects of this embodiment are as follows: by operating the stacking conveyor 3 on the operating frame 2, one of the driving rollers 31 is driven and controlled to be connected to the driving motor through a coupling for driving rotation, and a conveyor belt 32 is wound around the multiple driving rollers 31 to carry out overall rotation transportation of the multiple driving rollers 31, thereby realizing the addition of multiple inner tanks 102 by transporting them on the conveyor belt 32;

[0091] The inner tank body 102 transported by the conveyor belt 32 is added to the separation receiving roller 44, and the separation driver 41 drives the eccentric driving shaft 47 to rotate eccentrically at the eccentric part of the turntable. A separation transport disc 42 is fixed on the turntable, and a slide groove is provided on the separation transport disc 42 to limit the eccentric driving shaft 47. The eccentrically running eccentric driving shaft 47 drives the connected rotating roller 43 to rotate eccentrically around the center of the turntable of the separation driver 41 through the fixed seat, so that the rotating roller 43 slides longitudinally on the supporting slide 46 through the bearing seat, and at the same time drives the upper separation roller 45 to rotate through the gear meshing, and a buffer spring is provided between the separation receiving roller 44, the rotating roller 43 and the supporting slide 46. Buffering is performed, and the rotating rotating roller 43 drives the separating receiving roller 44 to rotate through the synchronous belt, and then through the separating receiving roller 44 and the semi-circular groove at the upper end of the rotating roller 43, so that when the separating receiving roller 44 is displaced downward, the inner tank body 102 is added and transported in the semi-circular groove of the separating receiving roller 44, and the inner tank body 102 is dropped to the specified position through the separating receiving roller 44 and the rotating roller 43, and then it is repeated in this way, so as to achieve stable adjustment of the direction and interval of the transported inner tank body 102 through the separator 4, so as to facilitate the stable state and directional interval transportation of multiple inner tank bodies 102 processed at the same time, and then add the inner tank body 102 to the spray conveyor 5.
