Description

Technical Field

[0001] This invention belongs to the field of water electrolysis hydrogen production technology, specifically relating to a portable device for driving the water electrolysis of solid alloy materials to produce hydrogen. Background Technology

[0002] Hydrogen production via the hydrolysis of solid alloy materials is considered one of the most advantageous methods among various hydrogen production approaches. The core advantage of this technology lies in the fact that the alloy material, acting as the hydrogen source, is stable at room temperature and pressure, facilitating storage and transportation, while the reaction only requires water, resulting in a theoretically high hydrogen yield. This makes it a promising application in scenarios such as drone endurance, portable power supplies, and emergency backup power.

[0003] The core challenge in engineering this process lies in precisely and stably controlling the reaction. Adding solid alloy materials to a water-filled reactor all at once or in batches is a method that offers little effective control over the reaction rate. Once started, the reaction typically proceeds rapidly, generating large amounts of hydrogen in a short time, causing a sharp rise in system pressure and temperature, posing safety hazards. Furthermore, when the external load's demand for hydrogen decreases or ceases, the ongoing reaction within the reactor leads to hydrogen waste and continuous pressure buildup.

[0004] The hydrolysis of solid alloy materials to produce hydrogen releases a large amount of heat, which is accompanied by the generation of water vapor in the reaction chamber. When water vapor gradually accumulates and adheres to the interface between the reaction chamber and the solid raw material chamber, it adsorbs some of the solid material at the interface, blocking the smooth progress of the reaction. The resulting metallic compound residue is in the form of a slurry or paste, and is corrosive and sticky.

[0005] To address these issues, some improvement schemes have attempted to regulate the hydrogen production rate by controlling the supply rate of water or alloys, but with limited success. Other technical solutions involve regulating the rate using mechanical valves, but these valves are prone to clogging or corrosion by slurry residues, resulting in low reliability over long-term use and poor regulation accuracy, making it impossible to respond to changes in demand in real time. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a portable device for hydrogen production through the hydrolysis of solid alloy materials. By setting up a detachable reaction chamber and a detachable gas storage chamber as independent functional modules, the reaction chamber is used for by-product cleaning and raw material resetting; the gas storage chamber is used as an independent hydrogen storage unit, realizing the separation of hydrogen production and storage in the device, and achieving the effect of precise control over both the total amount of hydrogen produced and the instantaneous rate.

[0007] To achieve the dual goal of precise control over the total amount and instantaneous rate of hydrogen production, this invention provides the following technical solution:

[0008] A portable device for hydrogen production by hydrolysis of solid alloy materials is disclosed. The device includes a reaction chamber, a solid raw material chamber and a liquid raw material chamber connected to the reaction chamber, and an opening and closing device is provided at the connection between the solid raw material chamber and the reaction chamber, and between the liquid raw material chamber and the reaction chamber.

[0009] Preferably, the reaction chamber is removably connected to the solid raw material chamber and the liquid raw material chamber.

[0010] Preferably, the opening and closing device at the connection between the solid raw material silo and the reaction chamber is a first aperture regulating valve, and the opening and closing device at the connection between the liquid raw material silo and the reaction chamber is a second aperture regulating valve.

[0011] Furthermore, both the first aperture regulating valve and the second aperture regulating valve include: a raw material through hole and blades.

[0012] Furthermore, the device also includes: a buffer chamber and a gas flow channel, the buffer chamber being disposed at the lower end of the liquid raw material chamber, the gas flow channel forming a cavity, the liquid raw material chamber being embedded within the gas flow channel cavity, the reaction chamber being connected to the buffer chamber through the gas flow channel, a first door being provided at the connection between the gas flow channel and the reaction chamber, and a second door being provided between the gas flow channel and the buffer chamber; the reaction chamber and the gas flow channel are detachably connected.

[0013] Furthermore, the device also includes: a gas storage chamber, which is detachably connected to the buffer chamber, and an air inlet is provided at the connection between the gas storage chamber and the buffer chamber, with a one-way valve installed at the air inlet.

[0014] Furthermore, a feed inlet is provided at the upper end of the solid raw material silo.

[0015] Furthermore, the reaction chamber is equipped with a transparent viewing window.

[0016] Compared with existing technologies, the present invention provides a portable device for driving the hydrolysis of solid alloy materials to produce hydrogen, which has the following advantages:

[0017] First, it achieves precise, on-demand hydrogen supply. By using detachable reaction chambers and detachable gas storage chambers as independent functional modules, and continuously adjusting their opening via a switch on the outer wall, it enables quantitative feeding of solid alloys. This controls the total hydrogen production potential from the source, overcoming the discontinuous and inefficient nature of traditional batch-based hydrogen production. It achieves precise control over both the total hydrogen production volume and the instantaneous rate, representing a leap from "uncontrollable" or "coarse control" to "precise control of both total volume and rate." The hydrogen production rate can be continuously and smoothly adjusted within a wide range according to demand, meeting the dynamically changing hydrogen needs of downstream equipment.

[0018] Secondly, the inherent safety and operational safety of the device are improved by using orderly gas path control logic and one-way valve design to eliminate the risk of leakage and backflow of hydrogen during hydrogen production, storage and replacement.

[0019] Third, it solves the problem of by-product treatment and achieves convenient maintenance. Through the design of the detachable reaction chamber, the cleaning and recycling of solid by-products becomes simple and thorough, avoiding the accumulation of residue that leads to a decline in device performance and environmental pollution. It achieves a by-product recovery rate of nearly 100%, while ensuring the cleanliness of the reaction chamber and maintaining the long-term stable performance of the device.

[0020] Fourth, the modular design makes the device compact and lightweight, optimizing portability and endurance. The use of quickly replaceable gas storage and reaction chamber modules makes the device lightweight and compact, while also enabling continuous operation with immediate use through module replacement. It can achieve long-term continuous hydrogen supply in environments without resupply, such as in the field, making it highly practical.

[0021] Fifth, the design of the transparent window and continuous switch on the outer wall lowers the technical threshold, allowing non-professionals to operate safely and effectively after simple training. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides the following solution, please refer to the appendix. Figure 1A portable device for hydrogen production by hydrolysis of solid alloy materials is disclosed. The device includes a reaction chamber 3, and a solid raw material chamber 2 and a liquid raw material chamber 4 connected to the reaction chamber 3. The reaction chamber 3 is provided with a transparent window. Opening and closing devices are provided at the connection points between the solid raw material chamber 2 and the reaction chamber 3, and between the liquid raw material chamber 4 and the reaction chamber 3. When the device is in use, the solid alloy material in the solid raw material chamber 2 enters the reaction chamber 3 to react. By adjusting the opening and closing devices at the connection points between the solid raw material chamber 2 and the reaction chamber 3, the amount of solid alloy material entering the reaction chamber 3 can be controlled, and the amount of solid reactant input can be precisely controlled. Material is added as needed, and the opening and closing devices are closed after the input is completed. After the input is completed, the device is inverted, and the amount of liquid raw material entering the detachable reaction chamber can be controlled by adjusting the opening and closing devices at the connection points between the liquid raw material chamber 4 and the reaction chamber 3, thereby further controlling the amount of hydrogen generated by the reaction of the solid alloy material and the liquid raw material.

[0028] In a preferred embodiment, the reaction chamber 3 is detachably connected to the solid raw material chamber 2 and the liquid raw material chamber 4; further, the upper end of the solid raw material chamber 2 is provided with a feed inlet 1.

[0029] When the device is in use, the solid raw material bin 2 can be replaced with an unused raw material bin filled with solid alloy material at any time, realizing the continuous operation capability of replacing modules and using them immediately; or the solid alloy material can be put into the solid raw material bin 2 from the feed port 1 to realize the continuous feeding of solid alloy material.

[0030] As a preferred embodiment, please refer to the appendix. Figure 3 The opening and closing device at the connection between the solid raw material silo 2 and the reaction chamber 3 is a first aperture regulating valve 8-1, and the opening and closing device at the connection between the liquid raw material silo 4 and the reaction chamber 3 is a second aperture regulating valve 8-2. Both the first aperture regulating valve 8-1 and the second aperture regulating valve 8-2 include: a raw material through hole 12 and a blade 13. In use, the size of the raw material through hole 12 is changed by the movement of the blade 13, thereby adjusting the material feeding amount.

[0031] As a preferred embodiment, please refer to the appendix. Figure 2 The portable device for hydrogen production by hydrolysis of solid alloy materials further includes: a buffer chamber 5 and a gas flow channel 7. The buffer chamber 5 is located at the lower end of the liquid raw material chamber 4, and the gas flow channel 7 is located around the liquid raw material chamber 4, forming a cavity. The liquid raw material chamber 4 is embedded in the cavity of the gas flow channel 7. The reaction chamber 3 and the buffer chamber 5 are connected through the gas flow channel 7. A first door 9 is provided at the connection between the gas flow channel 7 and the reaction chamber 3, and a second door 10 is provided between the gas flow channel 7 and the buffer chamber 5.

[0032] Furthermore, the reaction chamber 3 and the gas flow channel 7 are detachably connected.

[0033] As a preferred embodiment, please refer to the appendix. Figure 2 The portable device for hydrogen production by hydrolysis of solid alloy materials further includes: a gas storage chamber 6, which is detachably connected to the buffer chamber 5. An air inlet 11 is provided at the connection between the gas storage chamber 6 and the buffer chamber 5, and a one-way valve is installed at the air inlet 11.

[0034] When the entire device is running, adjust the opening of the first aperture regulating valve 8-1 and the second aperture regulating valve 8-2 to the maximum, open the feed port 1, and inject sufficient pure water of the required purity into the liquid raw material tank, and then close the first aperture regulating valve 8-1 and the second aperture regulating valve 8-2.

[0035] Solid alloy material is fed into solid raw material silo 2 through feed inlet 1. The amount of solid alloy material entering reaction silo 3 is controlled by adjusting the size of raw material through hole 12 of first aperture regulating valve 8-1. The amount of solid reactant fed is precisely controlled and fed as needed. After feeding is completed, first aperture regulating valve 8-1 is closed.

[0036] The portable device for hydrogen production by hydrolysis of solid alloy material is inverted, and the amount of liquid raw material entering the reaction chamber 3 is controlled by adjusting the size of the raw material through hole of the second aperture regulating valve 8-2, thereby further regulating the amount of hydrogen generated by the reaction of solid alloy material and liquid raw material.

[0037] After the reaction begins, the first chamber door 9 is opened first, followed by the second chamber door 10, so that the generated hydrogen gas enters the gas storage chamber 6 from the gas inlet. Since a one-way valve is installed at the gas inlet, the gas can only enter the gas storage chamber 6 from the buffer chamber 5, ensuring that no hydrogen leakage occurs in the chamber during hydrogen production and replacement.

[0038] The intensity of the reaction between the solid alloy material and the liquid raw materials is observed through the transparent window of reaction chamber 3. After the reaction is complete, the gas storage chamber 6 is removed for downstream hydrogen production. Solid waste generated during the reaction can be disposed of by removing reaction chamber 3. This flexible handling method allows for complete recycling of byproducts and ensures smooth operation of subsequent hydrogen production reactions. After the above process is completed, another empty gas storage chamber 6 is installed, and the above operation is repeated.
