Description

Technical Field

[0002] Under the dual pressures of the global energy crisis and environmental protection, hydrogen energy, with its advantages of zero pollution and high energy density, is regarded as the core carrier for realizing sustainable energy development. In recent years, countries have accelerated the layout of the hydrogen energy industry, and the demand for hydrogen in fields such as fuel cell vehicles and distributed energy has shown an explosive growth. According to the needs of users, the stored hydrogen is transported to the use terminal through a hydrogen supply device with appropriate parameters such as pressure and flow rate.

[0003] After retrieval, a Chinese patent with the publication number CN218819633U discloses an integrated solid-state hydrogen storage and supply device. This integrated solid-state hydrogen storage and supply device can adopt an internal heat conduction structure, that is, two heat exchange methods, namely a heat exchange busbar and an external single-tank heat exchange water jacket box, for heat management, which can better exert the advantages of small volume and large flow rate of the integrated device; and the single-tank heat exchange water jacket box is easy to conduct heat exchange with the plate heat exchanger of the fuel cell, improving the waste heat reuse rate of the fuel cell.

[0004] When the above hydrogen supply device is in use, it is not convenient to filter impurities in hydrogen. These impurities include moisture, particulate matter, sulfides, carbon monoxide, etc. In fuel cell applications, the impurities will poison the catalyst of the fuel cell, resulting in a sharp decline in battery performance; moisture will also dilute the electrolyte of the proton exchange membrane, destroying the proton conduction performance of the membrane and affecting the output power and stability of the battery.

[0010] It can be seen that in the above technical solution, the hydrogen in the shell is detected by the hydrogen leakage detector. When hydrogen leaks, the valve closes to prevent the hydrogen from entering the hydrogen supply machine main body through the second air pipe.

[0011] Further, a bottom frame is fixedly connected to the inner bottom end of the shell. An extrusion assembly is arranged on the bottom frame. The extrusion assembly includes a stepper motor, a positive and negative lead screw, two sliders, two slide rods, two extrusion frames and two gaskets.

[0027] The following specific embodiments illustrate the implementation manners of the utility model. Those who are familiar with this technology can easily understand other advantages and effects of the utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the utility model.

[0028] Refer to the attached drawings of the specification Figures 1-5 For the integrated hydrogen supply device for hydrogen production and storage of this embodiment, it includes a housing 1 and a hydrogen supply machine main body 2, and the hydrogen supply machine main body 2 is fixedly embedded and installed on one side of the housing 1. A housing door 3 is movably connected to the other side of the housing 1 through a hinge. A second air pipe 6 is fixedly communicated with one side of the hydrogen supply machine main body 2. The other end of the second air pipe 6 is fixedly communicated with a storage box 4, and the storage box 4 is fixedly installed inside the housing 1. A first air pipe 5 is fixedly communicated with the other side of the storage box 4. The bottom of the storage box 4 is movably connected with a box cover 13 through a buckle. A plurality of filter plates 11 are movably arranged on the top of the box cover 13. A plurality of clamping plates 12 are movably arranged on both sides of the plurality of filter plates 11, and one sides of the plurality of clamping plates 12 are respectively fixedly connected to the storage box 4 and the box cover 13.

[0029] Furthermore, a sealing gasket 14 is movably sleeved on the box cover 13, and the top of the sealing gasket 14 is in contact with the storage box 4.

[0030] Furthermore, a hydrogen leakage detector 10 is fixedly installed at the top end of the storage box 4, and a valve 9 is fixedly installed on the second air pipe 6.

[0031] Furthermore, a bottom frame 7 is fixedly connected to the inner bottom end of the housing 1. An extrusion assembly 8 is arranged on the bottom frame 7. The extrusion assembly 8 includes a stepper motor 801, a positive and negative lead screw 802, two sliders 803, two sliding rods 804, two extrusion frames 805 and two gaskets 806. The stepper motor 801 is fixedly installed at the rear side inside the bottom frame 7, and the end of the output shaft of the stepper motor 801 is fixedly connected to the positive and negative lead screw 802. The front end of the positive and negative lead screw 802 is movably connected to the bottom frame 7 through a bearing. Both sliders 803 are threadedly connected to the positive and negative lead screw 802, and the top ends of the two sliders 803 are respectively fixedly connected to the two extrusion frames 805. The opposite sides of the two gaskets 806 are respectively fixedly connected to the two extrusion frames 805. Both sliding rods 804 are fixedly installed inside the bottom frame 7, and the front ends of both sliding rods 804 penetrate through the two sliders 803. Two limiting rings 807 are movably arranged on the opposite sides of the two sliders 803, and a plurality of limiting rings 807 are respectively fixedly sleeved on the two sliding rods 804.

[0032] Among them, the hydrogen leakage detector 10 is used to detect the hydrogen in the housing 1. When hydrogen leaks, the valve 9 closes so that hydrogen cannot enter the hydrogen supply machine main body 2 through the second air pipe 6. When the hydrogen in the hydrogen storage bottle is used up, the stepping motor 801 is started. The stepping motor 801 drives the forward and reverse lead screw 802 to rotate. Since both sliders 803 are threadedly connected to the forward and reverse lead screw 802 and the two slide bars 804 limit the rotation of the two sliders 803, the forward and reverse lead screw 802 can drive the two sliders 803 to move away from each other, thereby driving the two pressing frames 805 and the two gaskets 806 to move away from each other, so as to release the fixation between the bottom frame 7 and the hydrogen storage bottle and replace the hydrogen storage bottle. Similarly, the hydrogen storage bottle is installed. The operation is simple and convenient to use. The limit ring 807 can prevent the slider 803 from contacting the stepping motor 801.

[0033] The usage method of this embodiment is as follows:

[0034] When in use, hydrogen is injected into the hydrogen storage bottle through the hydrogen production equipment, and the hydrogen storage bottle stores the hydrogen. Open the shell door 3 and place the hydrogen storage bottle on the bottom frame 7. Connect the first air pipe 5 to the air outlet end of the hydrogen storage bottle. The hydrogen in the hydrogen storage bottle can enter the storage box 4 through the first air pipe 5. The impurities in the hydrogen are filtered and purified by multiple different filter plates 11. The filtered hydrogen enters the hydrogen supply machine main body 2 through the second air pipe 6 and is supplied with hydrogen through the hydrogen supply machine main body 2. Open the buckle to release the lock between the box cover 13 and the storage box 4, and disassemble and replace the filter plate 11 in the storage box 4. The operation is simple and convenient for filtering the impurities in the hydrogen. Similarly, the box cover 13 is installed. The multiple clamping plates 12 can limit the deflection of the filter plate 11, and the sealing gasket 14 can improve the sealing performance between the box cover 13 and the storage box 4;

[0035] The different filter plates 11 include activated carbon filter plates, molecular sieve filter plates, metal mesh filter plates, ceramic filter plates, and ion exchange resin filter plates. The activated carbon filter plate adsorbs organic sulfides, benzene and other organic impurities. The molecular sieve filter plate has a selective adsorption effect on molecules with different polarities. The metal mesh filter plate blocks the solid particle impurities carried in the hydrogen by physical interception. The ceramic filter plate can filter the tiny solid particles and some bacteria in the hydrogen. The ion exchange resin filter plate removes the ionic impurities in the hydrogen by ion exchange;

[0036] The hydrogen supply machine main body 2 usually uses a compressor to compress the filtered hydrogen to increase the pressure of the hydrogen, so as to meet the requirements of different application scenarios. When hydrogen supply is required, the high-pressure hydrogen is transported to the hydrogen supply interface through a pipeline.
