Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology through hydrolysis of hydrogen storage materials, and in particular to a reaction device for hydrogen production through hydrolysis of magnesium-based solid hydrogen storage materials. Background Technology

[0002] With the increasing global demand for clean energy, hydrogen energy, as a clean and efficient secondary energy source, has broad application prospects. Magnesium-based solid hydrogen storage materials are considered to be one of the most promising hydrogen storage materials due to their advantages such as high hydrogen storage capacity, good chemical stability and relatively low cost. In order to realize the practical application of hydrogen production by hydrolysis of magnesium-based solid hydrogen storage materials, a reaction device is needed to prepare and hydrolyze them.

[0003] Most existing reaction devices directly feed raw materials and reagents into the reaction device for mixing and stirring. During feeding, the raw materials tend to accumulate at the outlet of the feed hopper, resulting in poor material flow or even complete blockage, which prevents the hydrolysis hydrogen production reaction from proceeding continuously. At the same time, the lack of a crushing structure means that the material cannot be effectively crushed and dispersed, which reduces the specific surface area of ​​the material and the contact area with water, thus slowing down the hydrolysis reaction rate and reducing the efficiency of hydrogen production.

[0004] Therefore, in view of the fact that most of the above-mentioned reaction devices directly feed raw materials and reagents into the reaction device for mixing and stirring, and lack a crushing structure, the materials cannot be effectively crushed and dispersed, resulting in a slow hydrolysis reaction rate and reduced hydrogen generation efficiency, a reaction device for hydrolysis of magnesium-based solid hydrogen storage materials to produce hydrogen can be designed. Utility Model Content

[0005] To overcome the problem that most reaction devices directly feed raw materials and reagents into the reaction device for mixing and stirring, and lack a crushing structure, the materials cannot be effectively crushed and dispersed, resulting in a slower hydrolysis reaction rate and reduced hydrogen generation efficiency, a reaction device for hydrogen production by hydrolysis of magnesium-based solid hydrogen storage materials is proposed.

[0020] Please see Figures 1-5 This utility model provides an embodiment of a reaction device for producing hydrogen by hydrolysis of magnesium-based solid hydrogen storage materials, including a reaction vessel 1 and support rods 2; a feeding assembly for feeding raw materials is installed on the right side of the reaction vessel 1, and an auxiliary assembly is provided between the feeding assembly and the reaction vessel 1; three sets of support rods 2 are provided at the bottom of the reaction vessel 1; the feeding assembly includes a feeding hopper 301, which is installed on the right side wall of the reaction vessel 1; a rotating rod 302 is rotatably connected inside the feeding hopper 301, and a stirring and crushing blade 303 is provided on the outside of the rotating rod 302.

[0021] Please see Figures 2-3 In this embodiment, a transmission bevel gear 304 is provided on the front side of the stirring and crushing blade 303, and an upper bevel gear 305 is connected above the transmission bevel gear 304. An upper vertical shaft 306 is provided at the middle position of the top of the upper bevel gear 305, and a pulley 307 is provided on the outer side of the upper vertical shaft 306. A servo motor 308 is provided at the middle position of the top of the reactor 1, and the output end of the servo motor 308 is connected to a coupling. A pulley 309 is provided on the outer side of the coupling of the servo motor 308, and a transmission belt 310 is connected to the outer side of the pulley 309 and the pulley 307. A stirring blade 311 is rotatably connected to the outer side of the coupling of the servo motor 308, and the stirring blade 311 is rotatably connected to the reactor 1. A bottom plate 312 is provided at the middle position inside the reactor 1, and a drying box 313 is installed at the bottom of the reactor 1. A connecting pipe with a control valve is connected between the drying box 313 and the bottom plate 312.

[0022] The stirring and crushing impeller 303 is connected to the servo motor 308 via a transmission bevel gear 304, an upper bevel gear 305, an upper vertical shaft 306, a first pulley 307, a second pulley 309, and a transmission belt 310. This multi-stage transmission structure effectively transmits the power of the servo motor 308 to the stirring and crushing impeller 303, enabling it to obtain sufficient speed and torque. This achieves efficient stirring and crushing of magnesium-based solid hydrogen storage materials, increases the contact area of ​​the reactants, and accelerates the hydrolysis reaction rate. A stirring blade 311 is rotatably connected to the servo motor 308 via a coupling. The stirring blade 311 rotates inside the reaction vessel 1, cooperating with the stirring and crushing impeller 303 to form multi-angle, all-around stirring, making the materials in the reaction vessel 1 more uniformly mixed. To further improve the efficiency and completeness of the reaction, a bottom plate 312 is installed inside the reactor 1, which can perform preliminary solid-liquid separation of the reaction products. The solid products remain on the bottom plate 312, while the liquid products can flow into the lower area through the connecting pipe between the bottom plate 312 and the drying chamber 313, facilitating further processing and collection of the products. The drying chamber 313 is installed at the bottom of the reactor 1, and the drying chamber 313 and the bottom plate 312 are connected by a connecting pipe with a control valve. When it is necessary to dry the products, the control valve on the connecting pipe can be opened to allow the preliminarily separated solid products to enter the drying chamber 313 for drying, avoiding the influence of moisture in the products on subsequent use or storage, and improving the quality and stability of the products.

[0023] Please see Figures 4-5 In this embodiment, the auxiliary components include a water storage tank 401, which is installed on the left side of the reactor 1. A stirring motor 402 is located at the rear end of the water storage tank 401, and a stirring rod is connected to the output end of the stirring motor 402. A heating box 403 is located at the top end of the stirring motor 402, and the heating box 403 is located on the left side of the reactor 1. An electric heating column 404 is installed inside the heating box 403, and the electric heating column 404 is located on the left side wall of the reactor 1. An outlet pipe 405 is connected to the outlet end of the water storage tank 401. A liquid inlet 406 is installed at the liquid outlet end of the liquid outlet pipe 405, and the liquid inlet 406 is snapped onto the feed hopper 301; two sets of external connecting seats 407 are provided on the right side of the liquid outlet pipe 405, a support rod 408 is installed on the left side of the external connecting seat 407, a spring 409 is provided on the outside of the support rod 408, a support 410 is provided on the left side of the liquid outlet pipe 405, and the left side of the spring 409 is fixedly connected to the left side wall of the support 410; a mounting base 411 is installed on the right side wall of the reactor 1, and the left side of the spring 409 is fixed to the mounting base 411.

[0024] The electric heating column 404 inside the heating box 403 heats the left side wall of the reactor 1, effectively controlling the reaction temperature and providing a suitable thermal environment for the hydrolysis hydrogen production reaction of the magnesium-based solid hydrogen storage material, accelerating the reaction rate and improving hydrogen production efficiency. A stirring motor 402 is installed at the rear of the water storage tank 401, with its output connected to a stirring rod, which stirs the water in the water storage tank 401 to ensure uniform water temperature. This also helps promote the mixing of water and the magnesium-based solid hydrogen storage material in the reactor 1, further improving reaction efficiency. The water storage tank 401 is connected to the liquid outlet pipe 40... 5. Connect the liquid inlet hopper 406 and snap it onto the feed hopper 301. This connection method ensures that water can be stably transported from the water storage tank 401 to the reactor 1, and the connection is tight to prevent liquid leakage. Two sets of external connecting seats 407 are set on the right side of the liquid outlet pipe 405. They are connected to the support 410 and the mounting seat 411 through the support rod 408 and the spring 409. This can buffer the external force impact that the liquid outlet pipe 405 may be subjected to, protect the pipeline system, and at the same time adapt to some small displacements or vibrations that may occur during the reaction process, thereby improving the stability and reliability of the device.

[0025] During operation, magnesium-based solid hydrogen storage material is fed into hopper 301. Servo motor 308 starts, driving the coupling to rotate. Pulley 2 309 on the outer side of the coupling rotates accordingly. Pulley 2 309 drives pulley 1 307 to rotate via transmission belt 310. Pulley 1 307 drives upper vertical shaft 306 to rotate. Upper bevel gear 305 on upper vertical shaft 306 rotates and meshes with transmission bevel gear 304. Transmission bevel gear 304 drives rotating rod 302 to rotate. The stirring and crushing blades 303 on the outside of rod 302 stir and crush the magnesium-based solid hydrogen storage material entering the feed hopper 301, making the raw material easier for subsequent reactions. An appropriate amount of water is added to the water storage tank 401, and the stirring motor 402 is started, driving the stirring rod to stir the water in the water storage tank 401 to ensure uniform water temperature. Simultaneously, the electric heating column 404 in the heating chamber 403 heats the water to a suitable temperature, providing suitable conditions for the hydrolysis reaction. The liquid outlet of the water storage tank 401... The outlet pipe 405 delivers heated and stirred water to the inlet hopper 406, which is connected to the feed hopper 301. Water enters the feed hopper 301 through the inlet pipe 406 and mixes with the stirred and crushed magnesium-based solid hydrogen storage material. The mixed magnesium-based solid hydrogen storage material and water enter the reactor 1 through the feed hopper 301. The stirring blades 311 on the coupling of the servo motor 308 rotate to stir the mixture in the reactor 1, making the reaction more complete. The magnesium-based solid hydrogen storage material and water undergo a hydrolysis reaction to produce hydrogen gas. The hydrogen gas produced by the reaction passes through the bottom plate 312 inside the reactor 1 and enters the drying box 313. The drying box 313 dries the hydrogen gas to remove any moisture it may contain, ensuring the dryness of the hydrogen gas. Through the cooperation between the spring 409 and the external coupling 407, a certain buffering and stabilizing effect is played during the liquid transportation process, ensuring the stability of the outlet pipe 405 when transporting liquid and preventing pipe shaking or damage caused by factors such as changes in liquid pressure.
