Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage and supply, and in particular to a solid-state hydrogen storage and supply device for a hydrogen refueling station. Background Art

[0002] Hydrogen energy is a secondary energy with abundant sources, green and low carbon, and wide application. It is considered to be the ultimate energy to promote sustainable development of global energy. In the development of the hydrogen energy industry, the storage and transportation of hydrogen is the key link between upstream hydrogen production and downstream hydrogen use. At present, there are three ways to store and transport hydrogen: high-pressure gas, liquid and solid. Among them, solid hydrogen storage has the advantages of high volume hydrogen storage density, good safety, and long storage time. It is considered to be the most promising hydrogen storage technology. Solid-state hydrogen storage refers to the use of materials to store hydrogen in solid materials by physical adsorption and chemical adsorption of hydrogen. The physical adsorption mechanism refers to the reversible adsorption of hydrogen molecules on porous materials with high specific surface area through van der Waals forces. In the chemical adsorption mechanism, hydrogen is generally combined with other elements by ionic bonds or covalent bonds to generate materials such as metal hydrides, which reversibly absorb and release hydrogen under certain conditions. In the existing technology, the capacity of physical adsorption substances is low, the hydrogen storage capacity is not high enough, and the contact efficiency between physical adsorption substances and hydrogen is low, resulting in a decrease in adsorption efficiency.

The top of the conveying carrier is fixedly connected with four groups of equally spaced positioning and placing components, and each group of positioning and placing components includes two transport docking platforms fixed on the conveying carrier. The outer surface of the hydrogen storage tank is fixedly sleeved with a heat-conducting ring fin. In the portable solid-state hydrogen storage device, a servo motor drives the pitch-adjusting screw to rotate, so that the movable disc moves to the left along the limiting rod until the movable disc drives the reset piston to slide to the left. And detach from the hydrogen filling pipeline, and then connect the hydrogen filling pipeline with the hydrogen storage tank, then hydrogen filling can be carried out in the hydrogen storage tank through the hydrogen filling pipeline, hydrogen is absorbed by the hydrogen storage material in the hydrogen storage tank, and heat is generated at the same time, the heat is conducted to the outer wall of the hydrogen storage tank by the heat conductive material, and is quickly discharged out of the hydrogen storage tank through the heat conductive ring fins, when the hydrogen is saturated, stop filling with hydrogen and close the hydrogen filling pipeline, although this patent solves the above problems, there are still problems of low storage capacity and low hydrogen input efficiency, so a solid-state hydrogen storage and supply device for hydrogen filling stations is proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a solid-state hydrogen storage and supply device for a hydrogen refueling station in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A solid hydrogen storage and supply device for a hydrogen refueling station, including a solid hydrogen storage tank. A support base is fixedly connected to the lower surface of the solid hydrogen storage tank. A hydrogen storage pipe is fixedly connected to the left side surface of the solid hydrogen storage tank. A hydrogen supply pipe is fixedly connected to the left side surface of the solid hydrogen storage tank. A support frame is fixedly connected to the left side surface of the solid hydrogen storage tank. A partition is fixedly connected to the right side of the inner wall of the solid hydrogen storage tank. An adsorption cylinder is rotatably connected to the left side surface of the partition. A connecting shaft is fixedly connected to the left end of the adsorption cylinder. A transmission shaft is rotatably connected to the left end of the inner wall of the solid hydrogen storage tank. An eccentric shaft is fixedly connected to the right end of the transmission shaft. An X-shaped transmission plate is hinged to the circumferential surface of the eccentric shaft. A movable shaft is fixedly connected to the right side surface of the X-shaped transmission plate. A connecting plate is hinged to the circumferential surface of the movable shaft. A cooling and heat dissipation device is arranged inside the solid hydrogen storage tank for quickly dissipating heat to make the structure of the porous solid adsorption material stable and thus adsorb hydrogen faster. A steam heating device is arranged inside the solid hydrogen storage tank for reducing the adsorption capacity of the porous solid adsorption material by heating, causing the adsorbed molecules to fall off and thus quickly releasing hydrogen. The left end of the transmission shaft is fixedly connected to a motor through an output shaft, and the motor is installed at the left end of the support base. The connecting plate is fixedly connected to the circumferential surface of the connecting shaft. Hydrogen is input into the solid hydrogen storage tank through the hydrogen storage pipe. The hydrogen is quickly adsorbed by the solid porous adsorption material wrapped around the inner wall of the solid hydrogen storage tank and the circumferential surface of the adsorption cylinder. The motor is started, and the motor drives the transmission shaft to rotate. The transmission shaft drives the eccentric shaft to rotate. The eccentric shaft drives the X-shaped transmission plate to rotate circumferentially along the axis of the transmission shaft. When the X-shaped transmission plate rotates circumferentially, it drives the four movable shafts to rotate circumferentially along the axis of the adsorption cylinder. The movable shafts drive the connecting plate to rotate along the axis of the adsorption cylinder. The connecting plate then drives the connecting shaft to rotate. The connecting shaft drives the adsorption cylinder to rotate, so that the adsorption cylinder rotates when hydrogen enters the inside of the solid hydrogen storage tank.

[0006] Preferably, the cooling and heat dissipation device includes heat conduction fins, a heat conduction ring, and heat pipes. The heat conduction fins are fixedly connected to the inner wall of the solid hydrogen storage tank. The heat conduction ring is arranged inside the solid hydrogen storage tank. The heat pipes are fixedly connected to the inner surface of the heat conduction ring. The cooling and heat dissipation device further includes a reciprocating lead screw, a limiting ring, a nut, a connecting piece, and a connecting rod. The reciprocating lead screw is fixedly connected to the right side surface of the eccentric shaft. The limiting ring is fixedly connected to the circumferential surface of the reciprocating lead screw. The nut is threadedly connected to the circumferential surface of the reciprocating lead screw. The connecting pieces are fixedly connected to both sides of the circumferential surface of the nut. The connecting rod is fixedly connected to the inner surface of the connecting piece. The circumferential surface of the heat conduction ring and the side of the heat conduction fins away from the inner wall of the solid hydrogen storage tank are in contact with each other. The heat pipes are fixedly connected to the circumferential surface of the connecting rod. The heat pipes and the circumferential surface of the adsorption cylinder are in contact with the right side surface of the solid hydrogen storage tank. During the process of re-storing hydrogen after hydrogen release, new hydrogen is input into the solid hydrogen storage tank. The residual heat in the solid hydrogen storage tank is conducted to the outer wall of the solid hydrogen storage tank through the heat conduction fins and then dissipated into the air. The residual heat near the adsorption cylinder is conducted to the heat conduction ring through the heat pipes, and then conducted to the heat conduction fins through the heat conduction ring. The rotation of the eccentric shaft drives the reciprocating lead screw to rotate along the axis of the transmission shaft. The reciprocating lead screw drives the nut to move left and right reciprocally. The nut drives the connecting piece to move reciprocally. The connecting piece drives the connecting rod to move reciprocally. The connecting rod then drives the heat pipes to move reciprocally, improving the contact area between the heat pipes and the surface of the adsorption cylinder, and thus improving the heat dissipation efficiency of the adsorption cylinder. The reciprocating movement of the heat pipes drives the heat conduction ring to move reciprocally when it is in contact with the heat conduction fins.

[0007] Preferably, the steam heating device includes a heating chamber, a gas transmission pipe, an exhaust valve, and an air inlet. The heating chamber is fixedly connected to the right side of the solid hydrogen storage tank. The gas transmission pipe is fixedly connected to the right side of the heating chamber. The exhaust valve is fixedly connected to the right side of the heating chamber. The air inlet is opened on the inner side of the partition. The steam heating device further includes a rubber sealing ring, an annular transmission plate, a piston sleeve, a connecting plate, and a piston cover. The rubber sealing ring is fixedly connected to the right side of the partition. The annular transmission plate is fixedly connected to the right end of the connecting rod. The piston sleeve is fixedly connected to the right side of the annular transmission plate. The connecting plate is fixedly connected to the circumferential surface of the piston sleeve. The piston cover is fixedly connected to one end of the connecting plate away from the piston sleeve. The circumferential surface of the piston sleeve is slidably connected to the inner surface of the partition. The inner surface of the piston sleeve is in contact with the circumferential surface of the reciprocating lead screw. The right end of the reciprocating lead screw is rotatably connected to the inner wall of the heating chamber. When the solid hydrogen storage tank stores hydrogen, the inside is in a vacuum state except for hydrogen. At this time, steam is input into the heating chamber through the gas transmission pipe. After the heating chamber is heated, it heats the inside of the solid hydrogen storage tank through the partition. The adsorption effect of the solid porous material on the adsorption cylinder decreases after being heated, so that hydrogen molecules are extruded. At this time, the hydrogen supply pipe is opened to extract hydrogen. And because the solid hydrogen storage tank is in a vacuum state, hydrogen does not contact oxygen, so no danger will occur during the heating process. At the same time, the heat is diffused to the inner wall of the solid hydrogen storage tank through the conduction of the heat pipe and the heat conduction ring, so that the inner wall of the solid hydrogen storage tank is heated. Furthermore, the adsorption effect of the solid porous adsorption material on the inner wall of the solid hydrogen storage tank decreases. When the connecting rod moves to the right, it drives the annular transmission plate to move to the right. The annular transmission plate drives the piston sleeve to move to the right. The piston sleeve drives the piston cover to move to the right through the connecting plate, so that the air inlet communicates with the heating chamber, and the heat enters the inside of the adsorption cylinder through the air inlet. When the connecting rod moves to the left, it drives the annular transmission plate and the piston sleeve to move to the left. The piston sleeve then drives the connecting plate and the piston cover to move to the left. The piston cover inserts into the air inlet, and the rubber sealing ring seals the piston cover and the partition.

[0008] Adopting the above technical solution, the present invention can bring the following beneficial effects:

[0009] 1. For the solid-state hydrogen storage and supply device for a hydrogen refueling station, hydrogen is quickly adsorbed by the solid porous adsorption material on the inner wall of the solid hydrogen storage tank and the circumferential surface of the adsorption cylinder. Through the arrangement of multiple adsorption cylinders, the area of the solid porous adsorption material is increased, and thus more hydrogen can be adsorbed, improving the hydrogen storage capacity. When hydrogen enters the inside of the solid hydrogen storage tank, the adsorption cylinder rotates, improving the contact efficiency between the solid porous material wrapped around the circumferential surface of the adsorption cylinder and hydrogen, and further improving the adsorption efficiency of hydrogen and the transportation efficiency during hydrogen storage.

[0010] 2. For the solid hydrogen storage and supply device used in a hydrogen refueling station, the waste heat near the adsorption cylinder is conducted to the heat conduction ring through a heat pipe, and then conducted to the heat conduction fins through the heat conduction ring, so that the temperature inside the solid hydrogen storage tank is uniformly reduced, improving the stability and adsorption effect of the solid porous adsorption material, and then adsorbing hydrogen more quickly, improving the adsorption efficiency during the hydrogen replacement process. The reciprocating movement of the heat pipe drives the heat conduction ring to reciprocate when it contacts the heat conduction fins, improving the heat exchange efficiency between the heat conduction ring and the heat conduction fins, and then improving the overall cooling effect of the device.

[0011] 3. For the solid hydrogen storage and supply device used in a hydrogen refueling station, the adsorption effect of the solid porous material on the adsorption cylinder decreases after being heated, so the hydrogen molecules are extruded. At this time, the hydrogen supply pipe is opened to extract hydrogen, which can extract hydrogen more conveniently and quickly, improving the hydrogen supply efficiency. After the air inlet is connected to the heating chamber, heat enters the inside of the adsorption cylinder through the air inlet, increasing the heat conduction area, promoting the heating efficiency of the solid particle material, and then extruding the hydrogen molecules more quickly.

A steam heating device 8 is provided inside the solid hydrogen storage tank 1 for reducing the adsorption capacity of the porous solid adsorption material by heating, causing the adsorbed molecules to fall off and thus rapidly releasing hydrogen. The left end of the transmission shaft 63 is fixedly connected to a motor through an output shaft, and the motor is installed at the left end of the support base 2. The connecting plate 67 and the circumferential surface of the connecting shaft 62 are fixedly connected. When hydrogen enters the inside of the solid hydrogen storage tank 1, the adsorption cylinder 61 rotates, improving the contact efficiency between the solid porous material wrapped around the circumferential surface of the adsorption cylinder 61 and hydrogen, and thus improving the adsorption efficiency of hydrogen and the transportation efficiency during hydrogen storage.

[0022] Working principle: Hydrogen is input into the solid hydrogen storage tank 1 through the hydrogen storage pipe 3. Hydrogen is rapidly adsorbed by the solid porous adsorption material wrapped around the inner wall of the solid hydrogen storage tank 1 and the circumferential surface of the adsorption cylinder 61. Through the arrangement of multiple adsorption cylinders 61, the area of the solid porous adsorption material is increased, and thus more hydrogen can be adsorbed, improving the hydrogen storage capacity. Start the motor, the motor drives the transmission shaft 63 to rotate, the transmission shaft 63 drives the eccentric shaft 64 to rotate, the eccentric shaft 64 drives the X-shaped transmission plate 65 to rotate circumferentially along the axis of the transmission shaft 63.

The heat pipe 73 is fixedly connected to the inner surface of the heat-conducting ring 72. The waste heat near the adsorption cylinder 61 is conducted to the heat-conducting ring 72 through the heat pipe 73, and then conducted to the heat-conducting fin 71 through the heat-conducting ring 72, so as to uniformly reduce the temperature inside the solid hydrogen storage tank 1, improve the stability and adsorption effect of the solid porous adsorption material, and thus adsorb hydrogen more quickly, improving the adsorption efficiency during the hydrogen replacement process. The cooling and heat dissipation device 7 further includes a reciprocating lead screw 74, a limiting ring 75, a nut 76, a connecting piece 77, and a connecting rod 78. The reciprocating lead screw 74 is fixedly connected to the right side surface of the eccentric shaft 64. The limiting ring 75 is fixedly connected to the circumferential surface of the reciprocating lead screw 74. The nut 76 is threadedly connected to the circumferential surface of the reciprocating lead screw 74. The connecting piece 77 is fixedly connected to both sides of the circumferential surface of the nut 76. The connecting rod 78 is fixedly connected to the inner surface of the connecting piece 77.

The heat pipe 73 is fixedly connected to the circumferential surface of the connecting rod 78. The heat pipe 73 is in contact with the circumferential surface of the adsorption cylinder 61 on the right side surface of the solid hydrogen storage tank 1. The reciprocating movement of the heat pipe 73 drives the heat-conducting ring 72 to reciprocate when it is in contact with the heat-conducting fin 71, improving the heat exchange efficiency between the heat-conducting ring 72 and the heat-conducting fin 71, and thus improving the overall cooling effect of the device.

[0024] Working principle: During the process of re-storing hydrogen after hydrogen release, new hydrogen is input into the solid hydrogen storage tank 1. The residual waste heat in the solid hydrogen storage tank 1 is conducted to the outer wall of the solid hydrogen storage tank 1 through the heat-conducting fin 71 and then dissipated into the air. The waste heat near the adsorption cylinder 61 is conducted to the heat-conducting ring 72 through the heat pipe 73, and then conducted to the heat-conducting fin 71 through the heat-conducting ring 72, so as to uniformly reduce the temperature inside the solid hydrogen storage tank 1, improve the stability and adsorption effect of the solid porous adsorption material, and thus adsorb hydrogen more quickly, improving the adsorption efficiency during the hydrogen replacement process.

The gas transmission pipe 82 is fixedly connected to the right side surface of the heating chamber 81. The exhaust valve 83 is fixedly connected to the right side surface of the heating chamber 81. The air inlet 84 is opened on the inner side of the partition plate 6. After the solid porous material on the adsorption cylinder 61 is heated, its adsorption effect decreases, so that hydrogen molecules are extruded. At this time, the hydrogen supply pipe 4 is opened to extract hydrogen, which can extract hydrogen more conveniently and quickly, improving the hydrogen supply efficiency. The steam heating device 8 further includes a rubber sealing ring 85, an annular transmission plate 86, a piston sleeve 87, a connecting plate 88, and a piston cover 89. The rubber sealing ring 85 is fixedly connected to the right side surface of the partition plate 6. The annular transmission plate 86 is fixedly connected to the right end of the connecting rod 78.

The circumferential surface of the piston sleeve 87 is slidably connected to the inner surface of the partition plate 6. The inner surface of the piston sleeve 87 is in contact with the circumferential surface of the reciprocating lead screw 74. The right end of the reciprocating lead screw 74 is rotatably connected to the inner wall of the heating chamber 81. After the air inlet 84 is communicated with the heating chamber 81, heat enters the inside of the adsorption cylinder 61 through the air inlet 84, increasing the heat conduction area, promoting the heating efficiency of the solid particle material, and further extruding hydrogen molecules more quickly.

[0026] Working principle: When the solid hydrogen storage tank 1 stores hydrogen, the inside is in a vacuum state except for hydrogen. At this time, steam is input into the heating chamber 81 through the gas pipeline 82. After the heating chamber 81 is heated up, it heats the inside of the solid hydrogen storage tank 1 through the partition plate 6. The adsorption effect of the solid porous material on the adsorption cylinder 61 decreases after being heated, so as to extrude hydrogen molecules. At this time, the hydrogen supply pipe 4 is opened to extract hydrogen, which can extract hydrogen more conveniently and quickly, improving the hydrogen supply efficiency. And because the solid hydrogen storage tank 1 is in a vacuum state, hydrogen does not contact with oxygen, so no danger will occur during the heating process. At the same time, the heat is diffused to the inner wall of the solid hydrogen storage tank 1 through the conduction of the heat pipe 73 and the heat conduction ring 72, so that the inner wall of the solid hydrogen storage tank 1 is heated, and then the adsorption effect of the solid porous adsorption material on the inner wall of the solid hydrogen storage tank 1 decreases. When the connecting rod 78 moves to the right, it drives the annular transmission plate 86 to move to the right. The annular transmission plate 86 drives the piston sleeve 87 to move to the right. The piston sleeve 87 drives the piston cover 89 to move to the right through the connecting plate 88, so that the air inlet 84 is communicated with the heating chamber 81, and the heat enters the inside of the adsorption cylinder 61 through the air inlet 84, increasing the heat conduction area, promoting the heating efficiency of the solid particle material, and then extruding hydrogen molecules more quickly. When the connecting rod 78 moves to the left, it drives the annular transmission plate 86 and the piston sleeve 87 to move to the left. The piston sleeve 87 then drives the connecting plate 88 and the piston cover 89 to move to the left. The piston cover 89 is inserted into the air inlet 84, and the rubber sealing ring 85 seals the piston cover 89 and the partition plate 6 to prevent heat from continuing to be transmitted into the solid hydrogen storage tank 1.
