Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage equipment technology, and in particular to a hydrogen release device based on thermal decomposition of hydrogen. Background Technology

[0002] With the increasing demand for clean energy, hydrogen energy has attracted much attention due to its high efficiency and cleanliness. However, existing hydrogen production methods suffer from high costs, high energy consumption, and environmental pollution. Solid hydrogen storage materials are a promising method for hydrogen storage and release, and the structure and performance of their thermal desorption hydrogen devices are crucial. When the solid material in the hydrogen storage tank releases hydrogen, the hydrogen release reaction requires the absorption of heat. If the required heat cannot be supplied in time, the internal temperature of the hydrogen storage tank will drop, the hydrogen release equilibrium pressure of the storage material will decrease accordingly, and the hydrogen release rate will slow down until it stops.

[0003] Current pyrolysis hydrogen decomposition devices suffer from problems such as complex structure, inconvenient operation, and low pyrolysis efficiency. For example, a graphene-magnesium-based solid hydrogen storage tank for rapid hydrogen release disclosed in application number 202211493642.0 has a heating rod inside and an insulation layer on the outside of the solid material tank for heat preservation. The heating device of this solid hydrogen storage tank is located inside the solid material tank where the solid hydrogen storage material is stored, which can only concentrate the heating of the middle area inside the solid material tank. The heating efficiency is low and the controllability is poor. Moreover, this solid hydrogen storage tank is designed as a whole structure and needs to be filled with hydrogen before it can be used. When replacing a new solid hydrogen storage tank, the heating rod and insulation layer must be replaced together. The replacement and disassembly steps are many, and the hydrogen-filled solid material tank cannot be replaced in time, making it inconvenient to use. Utility Model Content

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] This embodiment provides a hydrogen release device based on thermal decomposition of hydrogen, such as... Figures 1-6 As shown, the device includes a solid hydrogen reactor 2 for storing solid hydrogen storage material and a thermal decomposition hydrogen device 1 for heating the solid hydrogen reactor 2. The thermal decomposition hydrogen device 1 is used to heat the solid hydrogen reactor 2 to promote the thermal decomposition hydrogen reaction of the solid hydrogen storage material. The solid hydrogen reactor includes a reactor body and a temperature detection structure. The reactor body is cylindrical or rectangular, preferably cylindrical.

[0030] The thermal hydrogen decomposition device 1 includes a first enclosure 17 and a second enclosure 18. The first enclosure 17 and the second enclosure 18 are hinged to one side and openable and closable to the other side. Specifically, the first enclosure 17 and the second enclosure 18 are connected to one side by a hinge 101, and a latch 10 is provided on the other side. When the first enclosure 17 and the second enclosure 18 are closed, they can be locked in a closed state by the latch 10.

[0031] When the first containment body 17 and the second containment body 18 are closed, a receiving cavity 16 is formed inside them, and the solid hydrogen reactor 2 is detachably installed in the receiving cavity 16. The first containment body 17 and the second containment body 18 can be opened manually or electrically.

[0032] In this embodiment, by setting the first containment body 17 and the second containment body 18 to form an openable structure, the loading and unloading of the solid hydrogen reactor is more convenient. After the solid hydrogen storage material in the solid hydrogen reactor has completed thermal decomposition of hydrogen, the solid hydrogen reactor needs to be replaced or maintained. The movable sides of the first containment body 17 and the second containment body 18 can be opened manually or automatically to replace the solid hydrogen reactor, which simplifies the maintenance and replacement process, improves work efficiency, and reduces the complexity and difficulty of operation.

[0033] In a preferred embodiment, both the first containment body 17 and the second containment body 18 have a semi-circular cross-section. The first containment body 17 and the second containment body 18 can surround the outside of the solid hydrogen reactor 2 and uniformly heat the solid hydrogen reactor 2.

[0034] In addition, the cross-sections of the first containment body 17 and the second containment body 18 can also be U-shaped or other structures.

[0035] In one preferred embodiment, the thermal decomposition hydrogen device 1 includes an external support structure 11 and a heat insulation and heating assembly, the heat insulation and heating assembly being installed inside the external support structure 11. The external support structure 11 can be a support frame disposed outside the heat insulation and heating assembly to support the heat insulation and heating assembly, making the overall structure of the thermal decomposition hydrogen device 1 more stable.

[0036] like Figure 5As shown, the heat-insulating heating assembly includes an outer protective layer 12, a heating coil 14, a heat-insulating layer 13, and an inner protective layer 15. The inner protective layer 15, heating coil 14, heat-insulating layer 13, and outer protective layer 12 are arranged sequentially from the side closest to the solid hydrogen reactor 2 to the side furthest from the solid hydrogen reactor 2. Specifically, the first enclosure 17 and the second enclosure 18 are respectively provided with the heat-insulating heating assembly. Both the first enclosure 17 and the second enclosure 18 are provided with a half-circle of the inner protective layer 15, heating coil 14, heat-insulating layer 13, and outer protective layer 12. The heating coil 14 is spirally arranged in both the first enclosure 17 and the second enclosure 18, and the two heating coils 14 can be connected in parallel. Preferably, the outer protective layer 12 is made of a metal material such as aluminum plate or cold-rolled steel plate. The inner protective layer 15 is made of refractory fiber material. The heat-insulating layer 13 is aerogel insulation cotton or alumina fiber insulation cotton that does not contain inorganic materials.

[0037] The heating coil 14 effectively heats the solid hydrogen reactor, promoting the thermal decomposition of hydrogen from the solid hydrogen storage material. The thermal insulation layer 13 reduces heat loss during the reactor heating process, lowers energy consumption, and improves the pyrolysis efficiency of the solid hydrogen storage material; the outer protective layer 12 prevents accidental contact with high-temperature components. The multi-layered structure of the external support frame, outer protective layer 12, and inner protective layer 15 provides a stable and safe environment for the thermal decomposition of hydrogen.

[0038] Traditional pyrolysis hydrogen decomposition devices have low pyrolysis efficiency. In this embodiment, the pyrolysis hydrogen decomposition device is equipped with a heating coil 14, which can efficiently heat the area around the solid hydrogen reactor, promoting the pyrolysis hydrogen decomposition reaction of the solid hydrogen storage material. Simultaneously, the thermal insulation layer 13 reduces heat loss and improves energy utilization efficiency, thereby enhancing the pyrolysis efficiency.

[0039] In a preferred embodiment, the hydrogen release device based on pyrolysis of hydrogen in this embodiment further includes a control system, which is connected to the solid hydrogen reactor 2 and the pyrolysis hydrogen device 1. The control system is used to control the operation of the pyrolysis hydrogen device and monitor the temperature, pressure, and hydrogen flow rate inside the solid hydrogen reactor 2 in real time. Temperature sensors and pressure sensors are installed inside the solid hydrogen reactor 2 to detect the temperature and pressure inside the reactor 2, respectively.

[0040] As a preferred embodiment, such as Figure 1 and Figure 6As shown, the control system includes a control cabinet 5, a controller, a display screen 51, and operation buttons 52. The display screen 51 and operation buttons 52 are connected to the controller 56. The controller 56, display screen 51, and operation buttons 52 are all located on the control cabinet 5. The display screen 51 is used to display parameters such as temperature and pressure inside the solid hydrogen reactor 2, and the operation buttons are used to set parameters such as heating temperature and reaction time. The control cabinet 5 is also equipped with indicator lights 53 and an alarm 54. The control cabinet 5 is connected to the thermal hydrogen decomposition device 1 via a connecting frame 4, so that the control cabinet 5 and the thermal hydrogen decomposition device 1 are connected to form an integral structure, which facilitates their joint movement.

[0041] In this embodiment, the various sensors (pressure sensors, temperature sensors, etc.) and control valves (flow controllers, check valves, etc.) integrated in the control cabinet 5 can monitor and control the thermal decomposition hydrogen process in real time. Through the interaction of pressure, temperature, and the flow control valves, hydrogen is stably output within a certain pressure range, improving the stability and safety of hydrogen output.

[0042] The control cabinet integrates various control and display components such as operation buttons, displays, indicator lights, and alarms, enabling real-time monitoring and control of the thermal decomposition of hydrogen. Through a control system comprised of pressure sensors, temperature sensors, filters, flow controllers, and check valves, the system ensures stable hydrogen output within a specific pressure range through the interaction of pressure, temperature, and flow control valves.

[0043] In a preferred embodiment, a hydrogen inlet, a temperature detection inlet, and a hydrogen control valve are provided at the top of the solid hydrogen reactor 2. The hydrogen control valve and the temperature detection inlet are installed at the hydrogen inlet. The hydrogen inlet is connected to the control cabinet 5 via a hydrogen pipe 7 and is connected to the hydrogen output port 55 on the control cabinet 5. A flow control sensor is installed at the hydrogen inlet and is connected to the controller to monitor the hydrogen flow rate in the reactor in real time, thereby ensuring safe and stable production and output of hydrogen through strict control.

[0044] The control system also includes a cooling system 102, which is installed on the hydrogen pipe 7 to cool the output hydrogen. The cooling system can be a water-cooling system.

[0045] In a preferred embodiment, a cooling fan 6 is provided at the bottom of the thermal hydrogen decomposition device 1, and the cooling fan 6 is connected to the external support structure 11. The cooling fan 6 is used to cool the solid hydrogen reactor 2.

[0046] After the solid hydrogen storage material completes its thermal decomposition of hydrogen, the solid hydrogen reactor 2 needs to be replaced or maintained. In this embodiment, at the end of hydrogen release, the cooling fan 6 at the bottom of the thermal decomposition device 1 is activated to cool the solid hydrogen reactor 2, ensuring the safety and reliability of the device. When the temperature drops to the set value, the moving side of the thermal decomposition device can be manually or automatically opened to replace the solid hydrogen reactor, simplifying the maintenance and replacement process and improving work efficiency.

[0047] In a preferred embodiment, the hydrogen release device based on pyrolysis of hydrogen in this embodiment further includes an opening and closing mechanism 3. The opening and closing mechanism 3 includes a driving device and a transmission device (not shown in the figure). The transmission device is connected to the first or second containment body. The power output end of the driving device is connected to the transmission device and can drive the movable sides of the first and second containment bodies to open or close relative to each other. The driving device can be a power source such as a motor or cylinder, or it can be manually mechanically controlled for opening and closing. The opening and closing mechanism 3 is connected to a control system, which can control the opening and closing of the solid hydrogen reactor through the opening and closing mechanism to facilitate the loading and unloading of solid hydrogen storage materials.

[0048] In a preferred embodiment, casters 8 are installed on the bottom sides of both the control cabinet 5 and the thermal hydrogen decomposition device 1. The casters 8 facilitate the overall movement of the device.

[0049] In a preferred embodiment, the hydrogen release device based on pyrolysis of hydrogen in this embodiment further includes a handle 9, which is connected to the movable side of the first enclosure or the second enclosure. The opening and closing of the first enclosure and the second enclosure can be manually controlled by holding the handle.

[0050] Whether operated manually by pulling the handle or electrically by pressing the button to control the opening and closing mechanism 3, the movable side of the thermal hydrogen decomposition unit can be easily opened. The universal casters at the bottom of the movable side door further facilitate the transfer of the reactor, greatly improving operational convenience. These two opening and closing options provide users with different choices, meet different usage needs, and increase operational flexibility.

[0051] In this embodiment, the hydrogen release device based on pyrolysis hydrogen is opened manually or by the opening / closing mechanism 3. The movable side of the pyrolysis hydrogen release device 1 is equipped with universal casters at the bottom of the movable side door, allowing it to move in any direction. The solid hydrogen reactor 2, containing solid hydrogen storage material, is transferred into the pyrolysis hydrogen system. The movable side of the pyrolysis hydrogen release device 1 is manually closed. The hydrogen pipe 7 at the top of the solid hydrogen reactor 2 is connected to the control cabinet 5. The system is connected through the cooling system, pressure sensor, temperature sensor, filter, flow controller, and one-way valve system. The system switch is turned on, and the system starts running. Under the control of the control system, the pyrolysis hydrogen release device 1 begins to heat up. Under the interaction of pressure, temperature, and flow control valve, hydrogen is finally stably output within a certain pressure range. When hydrogen release is complete, the cooling fan 6 at the bottom of the pyrolysis hydrogen release device starts to cool the solid hydrogen reactor 2. When the temperature drops to the set value, the movable side of the pyrolysis hydrogen release device is manually opened to replace the solid hydrogen reactor 2.

[0052] The working principle of the hydrogen release device based on thermal decomposition in this embodiment is as follows:

[0053] First, by opening the movable side of the pyrolysis hydrogen device 1 via the opening and closing mechanism or manually, the solid hydrogen storage material-containing bulk hydrogen reactor 2 is inserted into the pyrolysis hydrogen device 1, and the movable side of the pyrolysis hydrogen device 1 is closed. The hydrogen pipe 7 between the solid hydrogen storage material-containing bulk hydrogen reactor 2 and the control cabinet 5 is connected. The heating temperature and reaction time are set via the control system, and the pyrolysis hydrogen device 1 begins heating the solid hydrogen storage material-containing bulk hydrogen reactor 2. When the temperature inside the solid hydrogen storage material-containing bulk hydrogen reactor 2 reaches the set value, the solid hydrogen storage material begins the pyrolysis hydrogen reaction. During the reaction, the control system monitors the temperature and pressure inside the reactor in real time and displays them on the screen. After the reaction is complete, the solid hydrogen storage material-containing bulk hydrogen reactor 2 is removed by opening the movable side of the pyrolysis hydrogen device 1 via the opening and closing mechanism or manually.

[0054] 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 modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
