Description

Technical Field

[0001] The present invention relates to the technical field of pipeline transportation, and particularly relates to a pipeline transportation system for solid-state storage in hydrogen production by electrolyzing water. Background Art

[0002] Hydrogen production by electrolyzing water and solid-state storage are important links in the hydrogen energy industrial chain. They jointly constitute an efficient conversion and storage system from renewable energy to hydrogen energy. Solid-state storage is an important way of hydrogen energy storage, which uses solid hydrogen storage materials to store hydrogen in a solid state. Compared with traditional gaseous and liquid hydrogen storage, solid-state hydrogen storage has the advantages of high volumetric hydrogen storage density, good safety, and long storage time.

[0003] Metal hydrides are the mainstream technical route for solid-state hydrogen storage. They combine with hydrogen through chemical reactions to form metal hydrides, thereby achieving the storage of hydrogen. When needed, these metal hydrides can be decomposed by heating and other means to release hydrogen for use. When using metal powder particles for hydrogen storage, hydrogen is directly transported through a pipeline to the inner cavity of the storage tank, and then the metal powder particles are put into the storage tank. Such storage is likely to cause insufficient reaction between hydrogen and metal particles, resulting in the need to additionally increase a stirring device to stir the particles. The stirred particles cannot ensure sufficient contact with hydrogen, and as the metal particles in the storage tank increase, it becomes more and more difficult to achieve stirring contact, unable to make full use of the transportation and circulation of hydrogen in the pipeline, and affecting the solid-state hydrogen storage effect of hydrogen production by electrolyzing water.

Detailed implementation manners

[0062] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0063] The present invention provides a pipeline transportation system for solid-state storage of hydrogen produced by electrolyzing water, as shown in Figure 1-8 the figure, which includes: a hydrogen gas tank 1, and a storage tank 2 for solid-state hydrogen storage is arranged on one side of the hydrogen gas tank 1. The storage tank 2 is used to load metal hydrides that react with hydrogen.

[0064] It further includes: a conveying pipeline 3, a feeding mechanism 4, a blower 5, an air inlet pipe 6 and an air outlet pipe 7. The conveying pipeline 3 is installed between the hydrogen tank 1 and the storage tank 2. The conveying pipeline 3 includes: a first pipeline 31, an elbow joint 32 and a second pipeline 33. The first pipeline 31 is installed at the gas outlet end of the hydrogen tank 1. The elbow joint 32 is installed at one end of the first pipeline 31. The second pipeline 33 is installed between the elbow joint 32 and the storage tank 2. The first pipeline 31, the elbow joint 32 and the second pipeline 33 are all composed of a protective pipe 301, a conveying pipe 302, balls 303 and rubber blocks 304. The conveying pipe 302 is sleeved in the inner cavity of the protective pipe 301 and is used for conveying hydrogen. A plurality of balls 303 are equidistantly embedded in the bottom sides of the inner wall of the conveying pipe 302, and the balls 303 are used for carrying the conveying pipe 302. A plurality of rubber blocks 304 are arranged in an annular array between the conveying pipe 302 and the protective pipe 301, and the plurality of rubber blocks 304 in the inner cavity of the protective pipe 301 are equidistantly arranged, so that the rubber blocks 304 and the balls 303 can stably support the conveying pipe 302, and the protective pipe 301 can safely protect the outer wall of the conveying pipe 302.

[0065] Among them, the protective tube 301 includes: an outer tube 3011, a light-shielding coating 3012, an elastic membrane 3013, an inner tube 3014, a heat-resistant coating 3015, a first compression spring 3016, a membrane touch switch 3017, and a patch 3018. The outer tube 3011 is arranged outside the conveying tube 302. Both the outer tube 3011 and the inner tube 3014 are made of polypropylene. The light-shielding coating 3012 is coated on the outer wall of the outer tube 3011. Through the light-shielding coating 3012, the influence of an open flame on the hydrogen in the inner cavity of the conveying tube 302 is reduced. The end of the elastic membrane 3013 is fixedly connected to the inner wall of the end of the outer tube 3011. The end of the inner tube 3014 is fixedly connected to the end of the outer tube 3011. The ball 303 and the rubber block 304 are both arranged in the inner cavity of the inner tube 3014. The heat-resistant coating 3015 is coated on the outer wall of the inner tube 3014. By coating the heat-resistant coating 3015, the heat-resistant performance of the outer wall of the inner tube 3014 is improved, facilitating the multi-layer protection of the conveying tube 302 by the protective tube 301, reducing the influence of heat on the hydrogen in the inner cavity of the conveying tube 302 in the inner tube 3014, and preventing the hydrogen explosion phenomenon during the hydrogen transportation process under harsh environments. The first compression spring 3016 is fixed between the heat-resistant coating 3015 and the elastic membrane 3013. The first compression spring 3016 is used for the elastic support of the elastic membrane 3013. When the outer tube 3011 is exposed to high temperature, the air between the outer tube 3011 and the elastic membrane 3013 expands, enabling the elastic membrane 3013 to deform and squeeze towards the inner tube 3014. The membrane touch switch 3017 is installed on the outer wall of the heat-resistant coating 3015. The patch 3018 is attached to the inner wall of the elastic membrane 3013. The membrane touch switch 3017 is connected to an alarm 8, and multiple membrane touch switches 3017 are electrically connected in series to the same alarm 8. The membrane touch switch 3017 is a contact switch, and the on-off alarm of the alarm 8 can be achieved through contact. When the elastic membrane 3013 expands, the patch 3018 squeezes and contacts the membrane touch switch 3017. The alarm 8 is fixed to the outer wall of the conveying pipeline 3 through a clamp. The alarm 8 is electrically connected to an external power supply through an external controller. The setting of the alarm 8 further improves the safety of the conveying pipeline 3 for hydrogen transportation and reduces the influence on hydrogen transportation in a high-temperature environment.

[0066] Further, the feeding mechanism 4 is installed at one end of the conveying pipeline 3 close to the storage tank 2. The feeding mechanism 4 is used for lifting and feeding metal powder. The feeding mechanism 4 includes: a fixing frame 41, a top plate 42, a feeding box 43, a blanking component 44 and an auxiliary component 45. The fixing frame 41 is fixed to the bottom of the second pipeline 33, and the bottom of the fixing frame 41 is set on the ground. The top plate 42 is fixed to the top of the fixing frame 41 through sealant. The middle parts of the fixing frame 41 and the top plate 42 form a cylindrical cavity structure. The second pipeline 33 is fixedly installed in a truncated form at the ends of the fixing frame 41 and the top plate 42, which is convenient for the fixing frame 41 and the top plate 42 to be stably fixed in the middle of the second pipeline 33, so that the hydrogen in the inner cavity of the second pipeline 33 can flow in the cavity between the fixing frame 41 and the top plate 42. And the length of one end of the second pipeline 33 close to the feed inlet of the storage tank 2 is shorter. The blanking end of the blanking component 44 is arranged close to the position of the feed inlet of the storage tank 2, so that under the blowing of hydrogen, the metal powder blanked by the blanking component 44 can conveniently enter the inner cavity of the storage tank 2. The feeding box 43 is fixed to the top of the top plate 42. The blanking component 44 is arranged in the cavity formed by the fixing frame 41 and the top plate 42. The blanking component 44 is used for blanking the metal powder particles in the inner cavity of the feeding box 43. The auxiliary component 45 is installed at the bottom of the blanking component 44. The auxiliary component 45 is used for the movable assistance of one end of the air outlet pipe 7.

[0067] Specifically, the blanking assembly 44 includes: a fixed pipe 441, a blanking pipe 442, a movable frame 443, an electric telescopic rod 444, a pulling block 445, a second compression spring 446, and a snap ring 447. The fixed pipe 441 is fixedly inserted through the top of the top plate 42. One end of the blanking pipe 442 is connected to the discharge port of the feeding box 43. The bottom of the blanking pipe 442 has a certain flexibility, enabling the blanking end of the blanking pipe 442 to perform swing-type blanking. The blanking pipe 442 is arranged inside the fixed pipe 441. The movable frame 443 is rotatably connected to the bottom of the fixed pipe 441 through a pin shaft. The other end of the blanking pipe 442 is slidably inserted and connected to one end of the movable frame 443. The other end of the blanking pipe 442 is arranged inside the inner cavity of the second pipe 33 near one end of the storage tank 2. One end of the electric telescopic rod 444 is rotatably inserted and connected to the top of the movable frame 443. The other end of the electric telescopic rod 444 is rotatably inserted and connected to the top inner wall of the top plate 42. The electric telescopic rod 444 is electrically connected to an external power supply through an external switch. By driving the electric telescopic rod 444, it is convenient to drive the movable frame 443 to swing at an angle of 120° - 150° with the fixed pipe 441, enabling the materials inside the blanking pipe 442 to be stably blanked while performing swing-type blanking, facilitating the metal powder particles to be lifted, and reducing the accumulation and residue of metal powder particles inside the second pipe 33. The pulling block 445 is slidably inserted through the side of the movable frame 443. The second compression spring 446 is sleeved on one end of the pulling block 445. The snap ring 447 is fixed to one end of the pulling block 445. The second compression spring 446 is fixed between the snap ring 447 and the inner wall of the adjacent movable frame 443. The snap ring 447 is used for clamping the outer wall of the blanking pipe 442. Through the elasticity of the second compression spring 446, it is convenient for the snap rings 447 on both sides of the movable frame 443 to squeeze and limit the outer wall of the blanking pipe 442, preventing the blanking pipe 442 from sliding out of the bottom of the movable frame 443 due to swinging, facilitating the stable blanking of metal powder particles, and by pulling the pulling block 445, the snap ring 447 can release the limit on the blanking pipe 442, facilitating the convenient adjustment of the position of the blanking pipe 442.

[0068] More specifically, the auxiliary component 45 includes: a first clamping rod 451, a sliding frame 452, a U-shaped block 453, a second clamping rod 454, and a screw rod 455. The first clamping rod 451 is fixed to one side of the bottom of the movable frame 443. The sliding frame 452 is slidably connected to the bottom of the movable frame 443. The U-shaped block 453 is slidably inserted through the end of the sliding frame 452, and the U-shaped block 453 is fixedly connected to the bottom of the movable frame 443. Through the setting of the U-shaped block 453, it is convenient to slide and limit the sliding frame 452, so that the sliding frame 452 can only move horizontally at the bottom of the movable frame 443. The second clamping rod 454 is fixed to the bottom of the sliding frame 452. The screw rod 455 is rotatably inserted through one end of the sliding frame 452, and the screw rod 455 is threadedly inserted and connected to the top of the first clamping rod 451. By rotating the screw rod 455, the sliding frame 452 is adjusted towards the direction of the first clamping rod 451, which is convenient for adjusting the distance between the first clamping rod 451 and the second clamping rod 454, facilitating the clamping of the air outlet pipe 7 with different diameters, enabling one end of the air outlet pipe 7 to be stably below the blanking pipe 442, making it more convenient for sufficient contact between hydrogen and the blanked metal powder particles, improving the generation of metal hydride, and facilitating the improvement of the solid hydrogen storage effect of hydrogen.

[0069] The fan 5 is installed on one side of the feeding mechanism 4. The air inlet pipe 6 is installed at the air inlet end of the fan 5. One end of the air inlet pipe 6 is inserted through one end of the conveying pipeline 3 close to the hydrogen tank 1. The air outlet pipe 7 is installed at the air outlet end of the fan 5.

The air outlet pipe 7 includes: a bent pipe 71 and a flexible pipe 72. The flexible pipe 72 is fixed to one end of the bent pipe 71 through a connecting piece. The flexible pipe 72 is arranged at the bottom of the blanking assembly 44 through the auxiliary component 45. The flexible pipe 72 is arranged at one end of the conveying pipeline 3 close to the storage tank 2, and the flexible pipe 72 is clamped between the first clamping rod 451 and the second clamping rod 454, facilitating the flexible pipe 72 to swing along with the movable frame 443, and facilitating the blowing of the metal powder and hydrogen into the inner cavity of the storage tank 2.

[0071] In use, the first pipeline 31, the elbow joint 32 and the second pipeline 33 are connected, and the first pipeline 31 and the second pipeline 33 are respectively connected to the hydrogen tank 1 and the storage tank 2. By starting the gas outlet valve in the inner cavity of the hydrogen tank 1, hydrogen can be transported through the conveying pipeline 3 towards the storage tank 2. By opening the feeding valve of the feeding box 43, metal powder particles can be fed through the feeding pipe 442. At the same time, the electric telescopic rod 444 and the fan 5 are started, which facilitates the electric telescopic rod 444 to drive the movable frame 443 to swing, so that the metal powder particles fed in the inner cavity of the feeding pipe 442 can swing and be lifted. At the same time, the hydrogen in the inner cavity of the second pipeline 33 is pressurized by the fan 5 through the air inlet pipe 6 and blown out through the air outlet pipe 7, so that the air outlet pipe 7 can blow the metal powder particles fed from the upper feeding pipe 442 into the inner cavity of the storage tank 2, which facilitates the feeding of hydrogen and metal powder into the inner cavity of the storage tank 2. At the same time, it is convenient for hydrogen to fully contact with metal powder particles to form metal hydride for hydrogen storage, reducing the consumption of resources and improving the storage efficiency and effect of solid hydrogen storage.
