Description

Technical Field

[0001] This utility model relates to the field of hydrogen production and storage technology, and more specifically, to an integrated portable device for instant hydrogen production and storage. Background Technology

[0002] Hydrogen energy is considered one of the most important clean energy sources of the future, especially in addressing climate change and reducing dependence on fossil fuels. With technological advancements, hydrogen production, storage, and fuel cell technologies have matured, leading to increasingly diverse applications of hydrogen energy, ranging from small portable devices to large transportation vehicles. Modern society has a growing demand for portable energy, particularly in outdoor activities, emergency rescue, and military applications. Traditional batteries and fuels are inconvenient to carry, and portable devices need to balance energy efficiency and environmental friendliness; hydrogen energy offers significant advantages in this regard.

[0003] However, while existing integrated hydrogen production and storage equipment utilizes traditional hydrogen production methods such as water electrolysis and natural gas reforming, which are effective, they suffer from limitations in portability. Furthermore, some portable devices face issues such as complexity, low efficiency, and poor intelligence, restricting the widespread application of hydrogen energy. Particularly in portable applications, such as outdoor emergency power supplies and charging swing devices, traditional technologies struggle to meet the demands for rapid, efficient, intelligent, and safe hydrogen production and storage.

[0004] CN202210620091.3 discloses an integrated hydrogen production, storage, and refueling device. This device integrates the three functions of hydrogen production, storage, and refueling. Although the overall size of the device is small, its portability is poor. CN201820854315.6 discloses a miniature integrated hydrogen generator. This device has better portability, but the energy consumption is high due to the use of traditional hydrogen production methods involving water electrolysis. CN201820107165.2 discloses a portable hydrogen production and supply device and a hydrogen fuel cell system. This device has a simple structure, is safe and controllable, and is easy to carry, but the reaction vessel is inconvenient to clean and the solid water electrolysis hydrogen production material is difficult to replace.

[0005] To meet the demands of portable devices, hydrogen production technology needs to be miniaturized and made more efficient, ensuring that the weight and size of the device remain within acceptable limits. Integrated devices for on-demand hydrogen production and storage require combining hydrogen production and storage functions into a single small unit, necessitating careful design considerations for the rational layout and efficient collaboration of all components. To achieve portability and efficiency, the device should be equipped with an intelligent control system capable of monitoring and regulating the hydrogen production and storage process in real time. Utility Model Content

[0006] The purpose of this invention is to provide a portable, efficient, and intelligent integrated hydrogen production and storage device to address the problems existing in the prior art. This device combines efficient hydrogen production with low-pressure, safe hydrogen storage; the reaction vessel is easy to clean, and the solid hydrolysis hydrogen production material is easy to replace.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] An integrated portable device for instant hydrogen production and storage includes a drying chamber, a hydrogen storage chamber, and a reaction chamber. The integrated portable device for instant hydrogen production and storage is a cavity structure. A first dividing layer and a second dividing layer divide the cavity structure from top to bottom into a drying chamber, a hydrogen storage chamber, and a reaction chamber.

[0009] The cavity structure contains a water storage tank. The bottom of the water storage tank is located in the hydrogen storage chamber above the second dividing layer and is connected to the second dividing layer. A valve is located at the outlet at the center of the bottom surface of the water storage tank. A rotating fan blade is located below the valve. A water flow hole is located on the second dividing layer corresponding to the rotating fan blade. Water flows through the valve, the rotating fan blade, and the dewatering plate into the reaction chamber. The rotation of the rotating fan blade causes the water to fall over the entire dewatering plate, thus falling evenly into the reaction chamber and making uniform contact with the solid hydrolysis hydrogen production material, ensuring sufficient contact and reaction of the material, thereby accelerating the reaction rate.

[0010] The reaction chamber has vertically arranged reaction layers, which are drawer-shaped structures. The outer plates of the reaction layers are equipped with sealing components at corresponding positions in the reaction chamber. After the reaction layers are pushed into the reaction chamber, they are sealed by the sealing components. Solid hydrolysis hydrogen production materials are evenly placed on the bottom plate of the reaction layers. The bottom plate of the upper reaction layers is equipped with permeation holes, through which unreacted water flows to the lower reaction layers. The bottom plate of the bottom reaction layers has no permeation holes.

[0011] As a further improvement to this technical solution:

[0012] The drying chamber is equipped with a gas-liquid separator containing an inorganic desiccant on its side wall. When hydrogen enters the drying chamber, the gas-liquid separator filters out water vapor from the hydrogen, thus purifying the hydrogen and reducing damage to hydrogen-using equipment.

[0013] The bottom plate of the reaction layer is provided with multiple rows of parallel reaction tanks, and solid hydrolysis hydrogen production materials are placed flat in the reaction tanks at equal intervals.

[0014] By setting up a reaction tank, the water flowing down from above collects in the reaction tank and fully contacts and reacts with the solid hydrolysis hydrogen production material to produce hydrogen quickly.

[0015] The solid hydrolysis hydrogen production material is wrapped in non-woven fabric and placed in the reaction layer.

[0016] Wrapping solid hydrolysis hydrogen production materials in non-woven fabric helps filter out impurities in the hydrogen gas.

[0017] The top of the reaction chamber is equipped with a drain plate, and the top of the drain plate is composed of swing blades with the same width as the reaction layer. One side of the swing blades is hinged to the drain plate. The bottom of the drain plate is a permeable layer. A small motor is installed at the drain plate. The small motor drives the swing blades to rotate around the hinge point through a linkage mechanism. The rotation angle of the swing blades changes the interval between the swing blades and the drain plate, thereby changing the amount of water flowing into the reaction chamber through the interval.

[0018] The linkage mechanism includes a connecting rod and a crankshaft push rod. Each swing blade has a connecting rod at its end. The swing blade is connected to the crankshaft push rod through the connecting rod. The crankshaft push rod is driven by a small motor to extend and retract.

[0019] With the above settings, the water volume can be better controlled using a small motor, thereby controlling the reaction speed.

[0020] The hydrogen storage chamber is equipped with a pressure sensor.

[0021] The pressure sensor and the small motor driving the drain plate are both connected to the controller. The controller controls the operation of the small motor on the drain plate based on the monitoring data from the pressure sensor, which in turn controls the oscillating blades, thereby adjusting the flow channel width. When the pressure inside the device is high, the flow channel width of the drain plate decreases to avoid the safety hazards of high-pressure hydrogen. If the amount of hydrogen used increases, the flow channel width of the drain plate can be increased to ensure a normal and continuous supply of hydrogen.

[0022] The hydrogen storage chamber is connected to the hydrogen-using equipment via an exhaust pipe, which is equipped with a switch valve, a safety valve, and a hydrogen flow rate meter in sequence.

[0023] The switch valve is located inside the safety valve and hydrogen flow meter, facilitating inspection and maintenance of these components. The hydrogen flow meter can monitor the amount and flow rate of hydrogen output. When the pressure inside the hydrogen storage chamber exceeds the safety limit, the safety valve automatically opens to release the excessive pressure, preventing the container from rupturing or exploding due to excessive pressure.

[0024] The water storage tank is equipped with a water inlet at the top, which extends outward to the top surface of the drying chamber. The water inlet has a threaded sealing cap to prevent hydrogen gas inside the device from leaking out through the water inlet.

[0025] The water storage tank is located in the middle of the overall device, which ensures the stability of the device.

[0026] Compared with related technologies, the beneficial effects of this utility model are:

[0027] (1) The reaction chamber of this utility model is a pull-out structure with three reaction layers. The channel for placing solid hydrolysis hydrogen production material in the reaction layer corresponds horizontally to the channel of the drain plate, which helps to improve the reaction rate and facilitates the replacement and recycling of solid hydrolysis hydrogen production material.

[0028] (2) The pressure sensor, small motor, and water tank valve at the top of the hydrogen storage chamber of this utility model are all connected to the controller. The controller controls the small motor on the dewatering plate to work based on the monitoring data of the pressure sensor, and further controls the swing blades to adjust the width of the flow channel. When the pressure value inside the device is high, the valve at the bottom of the water tank is closed, and the width of the flow channel of the dewatering plate is reduced to avoid the safety hazards of high-pressure hydrogen. If the amount of hydrogen required increases, the valve at the bottom of the water tank is opened, and the width of the flow channel of the dewatering plate is increased to ensure the normal and continuous supply of hydrogen.

[0029] (3) The water storage tank and drying chamber of this utility model are both located in the hydrogen storage chamber. The layout of each component is reasonable, achieving the purpose of high efficiency and portability. Finally, it realizes the function of a simple and intelligent integrated hydrogen production and storage device. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Example 1

[0037] like Figure 1 As shown, this utility model provides an integrated portable device for instant hydrogen production and storage, including a drying chamber 1, a hydrogen storage chamber 3, and a reaction chamber 7. The integrated portable device for instant hydrogen production and storage is a cavity structure. The first dividing layer 2 and the second dividing layer 4 divide the cavity structure from top to bottom into the drying chamber 1, the hydrogen storage chamber 3, and the reaction chamber 7.

[0038] The cavity structure is equipped with a water storage tank 10. The bottom end of the water storage tank 10 is located in the hydrogen storage chamber 3 above the second dividing layer 4 and is connected to the second dividing layer 4. A valve 8 is provided at the water outlet at the center of the bottom surface of the water storage tank 10. A rotating fan blade 9 is provided below the valve 8. A water flow hole is provided at the corresponding position of the second dividing layer 4 and the rotating fan blade 9. The water flows through the valve 8, the rotating fan blade 9, and the dewatering plate 5 and falls into the reaction chamber 7. The rotating fan blade 9 rotates so that the water flow covers the entire dewatering plate 5, so that it falls evenly into the reaction chamber 7 and comes into uniform contact with the solid hydrolysis hydrogen production material 17, ensuring that the material is fully contacted and fully reacted, thereby accelerating the reaction rate.

[0039] The reaction chamber 7 is provided with vertically arranged reaction layers 18, which are drawer-shaped structures. The outer plates of the reaction layers 18 are provided with sealing components at corresponding positions in the reaction chamber 7. After the reaction layers 18 are pushed into the reaction chamber 7, they are sealed by the sealing components. Solid hydrolysis hydrogen production material 17 is evenly placed on the bottom plate of the reaction layers 18. The bottom plate of the upper reaction layers 18 is provided with seepage holes, through which unreacted water flows to the lower reaction layers 18. The bottom plate of the bottom reaction layers 18 has no seepage holes.

[0040] The sealing components are paired magnetic sealing rings. A magnetic sealing ring is provided at the corresponding position of the outer side plate of the reaction layer 18 and the reaction chamber 7. When the two sealing rings are close together, they are attracted to each other magnetically, so that the outer side plate of the reaction layer 18 and the reaction chamber 7 are sealed.

[0041] The side wall of the drying chamber 1 is equipped with a gas-water separation device containing an inorganic desiccant.

[0042] Hydrogen enters the drying chamber 1, where a gas-water separation device filters out water vapor from the hydrogen, thus purifying the hydrogen and reducing damage to hydrogen-using equipment.

[0043] The bottom plate of the reaction layer 18 is provided with multiple rows of parallel reaction tanks, and the solid hydrolysis hydrogen production material 17 is placed flat in the reaction tanks at equal intervals.

[0044] By setting up a reaction tank, the water flowing down from above collects in the reaction tank and fully contacts and reacts with the solid hydrolysis hydrogen production material 17 to produce hydrogen quickly.

[0045] The solid hydrolysis hydrogen production material 17 is wrapped in non-woven fabric and placed in the reaction layer.

[0046] The solid hydrolysis hydrogen production material 17 is wrapped in non-woven gauze, which helps to filter out impurities in the hydrogen gas.

[0047] The top of the reaction chamber 7 is provided with a drain plate 5. The top of the drain plate 5 has a swing blade 20 with the same width as the reaction layer 18. One side of the swing blade 20 is hinged to the drain plate 5. The bottom of the drain plate 5 is a permeable layer. A small motor 19 is provided at the drain plate 5. The small motor 19 drives the swing blade 20 to rotate around the hinge point through a linkage mechanism. The rotation angle of the swing blade 20 changes the interval between the swing blade 20 and the drain plate 5, thereby changing the amount of water flowing into the reaction chamber 7 through the interval.

[0048] The linkage mechanism includes a connecting rod 21 and a crankshaft push rod 22. Each swing blade 20 has a connecting rod 21 at its end. The swing blade 20 is connected to the crankshaft push rod 22 through the connecting rod 21. The crankshaft push rod 22 is driven to extend and retract by a small motor 19.

[0049] With the above settings, the small motor 19 can be used to better control the water volume, thereby controlling the reaction speed.

[0050] The hydrogen storage chamber 3 is equipped with a pressure sensor 16.

[0051] The pressure sensor 16 and the small motor 19 on the drain plate 5 are both connected to the controller 6. The controller 6 controls the small motor 19 on the drain plate 5 based on the monitoring data from the pressure sensor 16, further controlling the oscillating blades 20 to adjust the flow channel width. When the pressure inside the device is high, the flow channel width of the drain plate 5 decreases to avoid potential safety hazards from high-pressure hydrogen. If the amount of hydrogen used increases, the flow channel width of the drain plate 5 can be increased to ensure a normal and continuous supply of hydrogen.

[0052] The hydrogen storage chamber 3 is connected to the hydrogen-using equipment through the exhaust pipe 12, and the exhaust pipe 12 is equipped with a switch valve 13, a safety valve 14 and a hydrogen flow meter 15 in sequence.

[0053] The switching valve 13 is located inside the safety valve 14 and the hydrogen flow meter 15, facilitating inspection and maintenance of these components. The hydrogen flow meter 15 can monitor the magnitude and flow rate of hydrogen output. When the internal pressure of the hydrogen storage chamber 3 exceeds the safety limit, the safety valve 14 automatically opens to release the excessive pressure, preventing the container from rupturing or exploding due to excessive pressure.

[0054] The water storage tank 10 is provided with a water inlet 11 at the top, which extends outward to the top surface of the drying chamber 1. The water inlet 11 has a threaded sealing cap to prevent hydrogen gas in the device from leaking out through the water inlet 11.

[0055] The water storage tank 10 is located in the middle of the overall device, which ensures the stability of the device.

[0056] It should be noted that the solid hydrolysis hydrogen production material 17 in this utility model is not limited to magnesium, zinc, calcium or their solid oxides, as long as the solid hydrolysis hydrogen production material 17 can react with water to generate hydrogen gas under normal temperature and pressure.

[0057] It should be noted that the integrated portable device for instant hydrogen production and storage in this invention can be applied to multiple fields such as portable electronic devices, drones, emergency power generation, and outdoor activities. In particular, this device has significant application value in remote areas lacking traditional energy supplies and in emergency situations.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
