Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology by water electrolysis, and in particular to an ultrasonic hydrogen production device by water electrolysis. Background Technology

[0002] With the development of human society and the accelerating pace of industrialization, the demand for energy is increasing daily. However, the extensive use of traditional fossil fuels such as coal, oil, and natural gas has led to both energy shortages and severe environmental pollution. Therefore, finding abundant and clean energy sources is imperative. Among these, hydrogen energy has attracted widespread attention due to its pollution-free combustion and high calorific value. Hydrogen production through water electrolysis, as an environmentally friendly and pollution-free energy preparation method, is an important means of producing hydrogen gas.

[0003] In existing technologies, hydrogen production is achieved by placing metallic magnesium in a reaction liquid (water or magnesium chloride solution). However, during the hydrolysis process, a magnesium hydroxide (Mg(OH)2) passivation layer easily forms on the surface of metallic magnesium, which hinders the further progress of the hydrolysis reaction, resulting in a decrease in hydrolysis kinetics and reduced hydrogen production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide an ultrasonic hydrolysis hydrogen production device to address the problem that the formation of a magnesium hydroxide passivation layer on the surface of metallic magnesium during the existing hydrolysis hydrogen production process hinders the further progress of the hydrolysis reaction, leading to a decrease in hydrolysis kinetics and low hydrogen production efficiency.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An ultrasonic hydrolysis hydrogen production device includes a reaction chamber, the interior of which is a closed space. A reaction cage is installed in the closed space, and several floating balls are placed inside the reaction cage. Several magnesium hydride blocks are placed inside each floating ball.

[0007] A liquid supply assembly is installed on the outside of the reaction chamber. The liquid supply assembly supplies reaction liquid into the reaction chamber. The reaction liquid enters the reaction cage in the closed space, and then enters the floating sphere to undergo a hydrolysis reaction with the magnesium hydride block, thereby generating hydrogen gas.

[0008] An ultrasonic vibration component is installed at the bottom of the reaction chamber. The ultrasonic vibration component drives the reaction chamber to generate ultrasonic vibration, thereby stripping the passivation layer attached to the surface of the magnesium hydride block during the hydrolysis reaction.

[0009] As a further improvement to the above technical solution:

[0010] The reaction chamber is hollow inside, and a through hole is opened on the top wall of the reaction chamber, with a cover plate installed at the through hole.

[0011] The cover plate is connected to the reaction chamber by a locking mechanism.

[0012] An airbag is installed between the cover plate and the reaction chamber to achieve a seal.

[0013] The reaction cage is suspended and installed in an enclosed space.

[0014] The reaction cage has several perforations on its wall for the reaction liquid to enter.

[0015] The structure of a single floating sphere is as follows: it includes two interconnected cavities, and air holes are opened on the walls of both cavities.

[0016] A single accommodating cavity comprises two hemispheres connected by snap-fit.

[0017] Each magnesium hydride block uses a porous magnesium hydride block.

[0018] The ultrasonic vibration assembly includes an ultrasonic generator, the output end of which is connected to an ultrasonic transducer, and the output end of which is connected to the bottom wall of the reaction chamber.

[0019] The ultrasonic generator drives the reaction chamber to generate ultrasonic vibrations through an ultrasonic transducer, thereby stripping the passivation layer from the surface of the magnesium hydride block within the enclosed space.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention features a compact and reasonable structure, and is easy to operate. By incorporating a reaction cage and a floating ball, the gas generated during the hydrolysis reaction can be ejected from the pores, causing the floating ball to tumble and disperse the magnesium hydride block. This ensures the hydrolysis reaction proceeds fully and effectively improves hydrogen production efficiency. Simultaneously, by incorporating an ultrasonic transducer and an ultrasonic generator, the passivation layer adhering to the surface of the magnesium hydride block can be peeled off based on ultrasonic vibration, further ensuring the hydrolysis reaction proceeds fully and improving hydrogen production efficiency.

[0022] This utility model also has the following advantages:

[0023] (1) By setting an openable cover, when it is closed, a closed space can be formed inside the reaction chamber, which makes it convenient to evacuate the closed space to obtain hydrogen with high purity; when it is opened, the reaction cage in the closed space can be replaced, which is convenient and quick to operate.

[0024] (2) By suspending the reaction cage in a closed space, the reaction liquid in the closed space can enter the reaction cage from the bottom wall of the reaction cage, so that the magnesium hydride block inside the reaction cage reacts fully and uniformly.

[0025] (3) The magnesium hydride block is made of porous magnesium hydride block, which helps the magnesium hydride block to fully contact and react with the reaction liquid. Attached Figure Description

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] The structure and function of this utility model are as follows:

[0035] like Figures 1-5 As shown, an ultrasonic hydrolysis hydrogen production device includes a reaction chamber 1. The reaction chamber 1 has an enclosed space inside, within which a reaction cage 8 is installed. Several floating balls 9 are placed inside the reaction cage 8, and several magnesium hydride blocks 10 are placed inside each floating ball 9. A liquid supply assembly is installed outside the reaction chamber 1, supplying reaction liquid into the reaction chamber 1. The reaction liquid enters the reaction cage 8 within the enclosed space, and then enters the floating balls 9 to hydrolyze with the magnesium hydride blocks 10, thereby generating hydrogen gas. An ultrasonic vibration assembly is installed at the bottom of the reaction chamber 1, driving the reaction chamber 1 to generate ultrasonic vibrations, thereby peeling off the passivation layer adhering to the surface of the magnesium hydride blocks 10 during the hydrolysis reaction. By setting up the reaction cage 8 and the floating balls 9, the gas generated during the hydrolysis reaction can be ejected from the vents 903, causing the floating balls 9 to tumble and disperse the magnesium hydride blocks 10, ensuring the hydrolysis reaction proceeds fully and effectively improving hydrogen production efficiency.

[0036] The reaction chamber 1 is hollow inside, with a through hole on its top wall. A cover plate 2 is installed at the through hole; the cover plate 2 is connected to the reaction chamber 1 by a locking mechanism; a gas bladder is installed between the cover plate 2 and the reaction chamber 1 to achieve a seal. By providing an openable and closable cover plate 2, when closed, a closed space is formed inside the reaction chamber 1, facilitating the evacuation of the closed space to obtain high-purity hydrogen; when opened, the reaction cage 8 inside the closed space can be replaced, making the operation convenient and quick.

[0037] In this invention, an outer cylinder 3 is installed on the outside of the reaction chamber 1, and a base 4 is installed on the bottom of the outer cylinder 3 to protect the reaction chamber 1. The outer cylinder 3 is made of stainless steel, and thermal insulation cotton is filled between the inner wall of the outer cylinder 3 and the outer wall of the reaction chamber 1. A heat circulation system is also installed between the inner wall of the outer cylinder 3 and the outer wall of the reaction chamber 1, which helps to maintain the stability of the internal temperature of the closed space during the hydrolysis reaction.

[0038] Several drain outlets are provided on the bottom wall of reaction chamber 1, and a drain pipe 13 is installed in each drain outlet so that the solution inside the enclosed space can be discharged through the drain pipe 13.

[0039] A gas pipe 12 is installed on the cover plate 2. The gas pipe 12 is connected to the hydrogen storage equipment through a gas pipeline. A hydrogen filter device is installed on the gas pipeline, which can further improve the purity of the hydrogen output from the hydrogen production device.

[0040] The liquid supply assembly includes several liquid tanks 5 for storing reaction liquids. Two adjacent liquid tanks 5 are connected by a connecting water pipe 7. One of the liquid tanks 5 is fitted with a water inlet pipe 6, which passes through the cover plate 2 and extends into the closed space, so that the reaction liquid can flow from the liquid tank 5 into the closed space.

[0041] In addition, within the enclosed space, the outlet of the water inlet pipe 6 faces the center of the reaction cage 8.

[0042] The reaction cage 8 is suspended in an enclosed space. Specifically, a hanging ring can be installed on the top of the reaction cage 8, and the hanging ring can be matched with a through hole opened on the top wall of the reaction chamber 1 to suspend the reaction cage 8.

[0043] By suspending the reaction cage 8 in a closed space, the reaction liquid in the closed space can enter the reaction cage 8 from the bottom wall of the reaction cage 8, so that the magnesium hydride block 10 inside the reaction cage 8 reacts fully and uniformly.

[0044] The reaction cage 8 has several openings 11 on its wall surface for the entry of the reaction liquid. The openings 11 are used for the reaction liquid in the enclosed space to enter the reaction cage 8. The reaction cage 8 is cylindrical, and the openings 11 are evenly distributed on the bottom wall surface and the outer circumference surface of the reaction cage 8.

[0045] like Figure 4 As shown, the structure of a single floating sphere 9 includes two interconnected accommodating cavities 902, each with an air hole 903 on its wall. The floating sphere 9 has a double-headed structure and is made of TPX material, which has excellent heat resistance and chemical resistance.

[0046] The two accommodating cavities 902 are connected by a connecting pipe 901. The connecting pipe 901 is hollow inside, which allows the magnesium hydride block 10 to move between the two accommodating cavities 902 through the connecting pipe 901. Furthermore, a through hole is provided on the wall of the connecting pipe 901, which allows the magnesium hydride block 10 to react in the connecting pipe 901.

[0047] Each accommodating cavity 902 comprises two hemispheres connected by snap-fit. In this invention, the accommodating cavity 902 is spherical and is formed by two hemispheres snap-fitted together. By adopting a snap-fit ​​connection method, the magnesium hydride block 10 can be conveniently and quickly placed into the accommodating cavity 902.

[0048] like Figure 5 As shown, each magnesium hydride block 10 is a porous magnesium hydride block. Several reaction pores are provided on each magnesium hydride block 10, which helps the magnesium hydride block 10 to fully contact and react with the reaction liquid.

[0049] The ultrasonic vibration assembly includes an ultrasonic generator, the output of which is connected to an ultrasonic transducer, and the output of the ultrasonic transducer is connected to the bottom wall of the reaction chamber 1. The ultrasonic generator drives the reaction chamber 1 to generate ultrasonic vibrations through the ultrasonic transducer, thereby peeling off the passivation layer on the surface of the magnesium hydride block 10 within the enclosed space. By setting up the ultrasonic transducer and the ultrasonic generator, the passivation layer attached to the surface of the magnesium hydride block 10 can be peeled off based on ultrasonic vibration, thereby ensuring that the hydrolysis reaction proceeds fully and further improving the hydrogen production efficiency.

[0050] The working process of this utility model is as follows:

[0051] Magnesium hydride block 10 is placed in floating ball 9, then placed in reaction chamber 1, cover plate 2 is closed, and hydrolysis process is started through control system.

[0052] After the control program is started, the enclosed space is first evacuated to remove excess air from reaction chamber 1. After the evacuation is completed (vacuum degree reaches 0.2 MPa), the pressure is maintained and self-checked (vacuum degree can be stabilized at 0.15 MPa). After there is no air leakage alarm, the process proceeds to the subsequent hydrolysis and hydrogen charging process.

[0053] The first water pump is started, allowing the reaction liquid (water or magnesium chloride solution) in the liquid tank 5 to enter the closed space through the water inlet pipe 6. Initially, the magnesium hydride block 10 in the reaction chamber 1 will undergo a violent hydrolysis reaction. As the liquid volume in the reaction chamber 1 increases, the floating ball 9 in the reaction cage 8 gradually floats. Due to the large amount of hydrogen produced by the hydrolysis reaction, the hydrogen is ejected from the gas hole 903, causing the floating ball 9 to tumble. This causes the magnesium hydride block 10 in the containment cavity 902 to break up and ensure that it is in full contact with the reaction liquid. At this time, the valve in the gas pipe 12 is opened, and the hydrogen in the closed space enters the downstream hydrogen storage equipment for storage through the gas pipeline.

[0054] In the middle and late stages of the hydrolysis reaction, the ultrasonic generator is started and the ultrasonic transducer is driven to output ultrasonic vibration, thereby peeling off the passivation layer attached to the surface of the magnesium hydride block 10 based on the ultrasonic vibration, thus promoting the full progress of the hydrolysis reaction.

[0055] The gas pipeline is also equipped with a flow meter and a pressure control valve to monitor the flow rate and pressure of hydrogen at the inlet of the hydrogen storage equipment. When the pressure of hydrogen at the inlet of the hydrogen storage equipment reaches 0.2 MPa, the control system starts to stop the hydrolysis reaction, starts the second water pump, and pumps out the waste liquid in the reaction chamber 1 through the drain pipe 13. The flow rate of hydrogen entering the hydrogen storage equipment gradually decreases until the waste liquid is drained and the hydrolysis reaction stops, thereby ensuring that the internal pressure of the hydrogen storage equipment is greater than 0.2 MPa and less than 0.5 MPa, which is within the safe range.

[0056] After hydrogen production is completed, open cover plate 2, remove floating ball 10, and perform subsequent processing on the recovered waste.

[0057] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
