This technology mainly utilizes porous materials to physically adsorb hydrogen or chemically react with hydrogen in a low-temperature environment to achieve hydrogen storage.

[0003] In practical use, most existing hydrogen storage devices use porous materials in powder form. When hydrogen enters the device, it inevitably carries fine dust, which can gradually clog the hydrogen delivery pipeline, increasing the flow resistance of the hydrogen, reducing the delivery efficiency, and even causing abnormal pressure increases in the pipeline, leading to safety hazards. Therefore, there is a need for a low-temperature solid-state hydrogen storage device that can remove the fine dust carried in the hydrogen, greatly improve the purity of the hydrogen, reduce the damage of dust to subsequent hydrogen-using equipment, and extend the service life of the equipment.

[0033] Please see Figure 1-4 As shown, this embodiment is a low-temperature solid-state hydrogen storage device, comprising:

[0034] Device housing 100;

[0035] The dust removal component includes an air inlet 200, a pipe body 201, a cyclone separator 202, a filter inner cavity 203, a rotating rod 205, an outer ring 206, an inner ring 208, and a filter screen 209. The air inlet 200 is connected to one end of the top of the device housing 100, the pipe body 201 is connected to the top of the air inlet 200, the filter inner cavity 203 is located at one end of the outer surface of the pipe body 201, the cyclone separator 202 is located at one end of the outer surface of the filter inner cavity 203, the rotating rod 205 is connected to the middle of the filter inner cavity 203, the outer ring 206 and the inner ring 208 are both connected to the outer surface of the rotating rod 205, and the filter screen 209 is detachably connected between the outer ring 206 and the inner ring 208.

[0036] The cyclone separator 202 uses centrifugal force to separate larger dust particles from hydrogen and deposit them in the dust collection chamber at the bottom of the separator. The filter chamber 203 has multiple filter screens 209 distributed inside, which further filter smaller dust particles. It has high filtration accuracy and low temperature resistance, and can remove fine dust carried in hydrogen. It can remove dust particles of different sizes mixed in with hydrogen.

[0037] The dust removal component also includes a conveying pipe 204 and a turntable 207. The conveying block pipe is connected to both ends of the outer surface of the filter inner cavity 203 and is respectively connected to the pipe body 201 and the cyclone separator 202. The turntable 207 is connected to the outer surface of the rotating rod 205.

[0038] The inlet 200, the pipe body 201, and the delivery pipe 204 are connected to facilitate the transfer of hydrogen.

[0039] It also includes a fixing component, which includes a collar 300, which is connected to the inner wall of the inner ring 208 and sleeved on the outer surface of the rotating rod 205.

[0040] The collar 300 is sleeved on the outside of the rotating rod 205, which facilitates the installation and removal of the outer ring 206 and the inner ring 208 that connect to the outside.

[0041] The fixing component also includes a socket 302 and a rod 303. The rotating rod 205 and the collar 300 are both provided with sockets 302, and the rod 303 is inserted and connected to the inside of the socket 302.

[0042] After the collar 300 is fitted onto the outside of the rotating rod 205, the insert rod 303 is inserted into the inside of the insertion hole 302 to fix the fitted collar 300.

[0043] The fixing component also includes an inner groove 301 and a fastening ring 304. The inner groove 301 is provided on the outer wall of the filter inner cavity 203, and the fastening ring 304 is connected to both ends of the outer surface of the insertion rod 303.

[0044] The fastening rings 304 are fixed at both ends of the insertion rod 303 to prevent the insertion rod 303 from shifting or falling off.

[0045] Working principle: First, the cyclone separator 202 and the filter chamber 203 are installed outside the air inlet 200. Hydrogen gas first enters the interior of the cyclone separator 202, where centrifugal force separates larger dust particles from the hydrogen gas, which are then deposited in the dust collection chamber at the bottom of the separator. The filter chamber 203 contains multiple filter screens 209, which further filter smaller dust particles, providing high filtration accuracy and low-temperature resistance, effectively removing fine dust carried in the hydrogen gas. Dust is greatly reduced, which improves the purity of hydrogen, reduces the damage of dust to subsequent hydrogen-using equipment, and extends the service life of the equipment. As the usage time increases, the turntable 207 is connected to the inner wall of the conveying pipe 204. The fastening ring 304 can be removed, the insertion rod 303 can be pulled out, so that the insertion rod 303 is separated from the insertion hole 302, and the collar 300 is separated from the rotating rod 205 in turn. The outer ring 206 and the inner ring 208 can be removed, and the internal filter screen 209 can be maintained or replaced for continued use in the future.

[0046] Please see Figure 1 , Figure 2 , Figure 5As shown, this embodiment, based on the above embodiment, further includes a sealing component. The sealing component includes a guide rod 400, a first sealing half-ring 402, and a second sealing ring 405. The guide rod 400 is connected to one end of the top of the device housing 100, the first sealing half-ring 402 is connected to the lower part of the outer surface of the guide rod 400, and the second sealing ring 405 is connected to the upper part of the outer surface of the guide rod 400. The first sealing half-ring 402 and the second sealing half-ring correspond to each other.

[0047] By using sealing half-ring 402 and sealing half-ring 2 to surround the gap between pipe body 201 and delivery pipe 204, the sealing performance can be increased.

[0048] The sealing component also includes a limiting disc 401, a first support block 403, a fixing ring 404, and a second support block 406. The limiting disc 401 is connected to the top of the guide rod 400, the first support block 403 is connected to both ends of the outer surface of the first sealing half ring 402, the second support block 406 is connected to both ends of the outer surface of the second sealing half ring, the fixing ring 404 is connected to the bottom of the first support block 403, and the guide rod 400 is connected through the middle of the second support block 406.

[0049] The guide rod 400 extends through the outside of the guide rod 400, allowing the sealing half ring 2 to be adjusted vertically outside the guide rod 400, facilitating installation and sealing.

[0050] The sealing component also includes a side plate 407 and a locking rod 408. The side plate 407 is connected to the bottom of the support block 406, and the locking rod 408 is connected to one side of the outer surface of the side plate 407.

[0051] Rotate the locking rod 408 so that it is clamped on the outside of the guide rod 400, thus fixing the position of the sealing half ring after it has moved.

[0052] Working principle: First, after the pipe body 201, cyclone separator 202 and conveying pipe 204 are connected, the second support block 406 can move up and down outside the guide rod 400, moving the second sealing half ring to the lower part and fitting together with the first sealing half ring 402. This allows the first sealing half ring 402 and the second sealing half ring to surround the gap between the pipe body 201, cyclone separator 202 and conveying pipe 204, improving the sealing performance after installation. Then, the locking rod 408 is rotated, clamping the locking rod 408 on the outside of the guide rod 400, fixing the position of the second sealing half ring after it has moved.
