Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and more particularly to a small integrated air supply device for a cross-medium vehicle. Background Art

[0002] To achieve the long-term endurance, rapid water exit, and underwater drag reduction capabilities of the inter-substance vehicle, a sustainable energy supply system, a ballast propulsion system, and an underwater drag reduction system were designed accordingly. The sustainable energy supply system is the core of these three systems, responsible for powering the entire vehicle and providing the energy for the other two systems to perform their intended functions. The air supply system, at the heart of the sustainable energy supply system, is responsible for seawater filtration, electrolysis, and hydrogen and oxygen purification. Without this system, the entire vehicle's intended functions would be impossible. Therefore, designing a small, integrated air supply system is crucial for this inter-substance vehicle. The small size and compact layout of inter-substance vehicles limit the space available for the air supply system. The inter-substance vehicle proposes to address the endurance issue by employing a sustainable energy supply system, the water exit issue by employing a ballast propulsion system, and the water drag issue by employing an underwater drag reduction system. The functions of these systems require a continuous replenishment of hydrogen and oxygen. Therefore, the air supply system aims to address the inter-substance vehicle's energy and power supply. Traditionally, seawater filtration, water electrolysis, and hydrogen and oxygen separation and purification functions are independently implemented by seawater filters, water electrolysis devices, and gas-liquid separators, respectively. The independence of the devices results in a large overall space occupation. Summary of the Invention

DETAILED DESCRIPTION

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, the small integrated air supply device for a trans-media vehicle of the present invention includes a filter housing 13, which is divided into two parts by a central partition. The filter housing 13 includes a seawater filter, a water electrolysis device, and a gas-liquid separation device. The seawater filter is used to provide pure seawater during the water electrolysis process, the water electrolysis device is used to generate the hydrogen and oxygen required by the trans-media vehicle, and the gas-liquid separation device is used to extract pure oxygen and recover water vapor during the water electrolysis process. The seawater filter is located on the left side of the filter housing 13, the gas-liquid separation device is located on the right side of the filter housing 13, and the water electrolysis device is located on the top of the filter housing 13. A sealing ring gasket 8 is provided at the bottom of the filter housing 13, an anode pressure plate 6 is provided at the bottom end of the seawater filter, and a cathode pressure plate 1 is provided at the top end of the seawater filter. The bottom anode pressure plate 6 and the top cathode pressure plate 1 are both provided with a water inlet 101, an oxygen outlet 301, and a hydrogen outlet 201.

[0029] The function of the seawater filtration device is to filter seawater, with the aim of filtering out impurities in the seawater, preventing impurities from corroding the electrode plates and affecting the electrolysis performance, thereby extending the service life of the gas supply device. The function is realized as follows: after the seawater enters the seawater filtration chamber 103 from the water inlet 101, it passes through the impurity filter membrane 4, the element filter membrane 3 and the gas barrier filter membrane 2 (blocking the passage of gas) in succession. The impurity filter membrane 4 and the element filter membrane 3 are used to filter macroscopic impurity particles and microscopic impurity elements in the seawater, and the gas barrier filter membrane 2 is used to prevent the oxygen generated by water electrolysis from escaping from the water inlet 101. The water electrolysis device realizes the water electrolysis function, with the aim of producing hydrogen and oxygen for use in sustainable energy supply systems, ballast propulsion systems and underwater drag reduction systems. The functional process is as follows: treated seawater enters the anode reaction chamber 205. The oxygen generated by electrolysis is filtered and purified through a three-layer gas-liquid filter membrane before being discharged from the oxygen outlet 301. The hydrogen ions generated by electrolysis pass through the proton exchange membrane 21 and reach the cathode reaction chamber 206, where they gain electrons and generate hydrogen gas, which is discharged from the hydrogen outlet 201. Since water cannot pass through the proton exchange membrane 21 from the anode reaction chamber 205 to the cathode reaction chamber 206, the hydrogen does not require gas-liquid separation and purification. The gas-liquid separation device achieves gas-liquid separation, its purpose being to filter out water contained in the oxygen and ensure the purity of the obtained oxygen. The functional process is as follows: the oxygen generated by electrolysis is filtered layer by layer through the three-layer water-repellent filter membrane 10, removing any mixed water, and then discharged from the oxygen outlet 301. The water-repellent filter membrane 10 in the gas-liquid separation module performs the opposite function to the gas-repellent filter membrane 2 in the seawater filtration module, namely, it allows gas to pass but not liquid. The three-layer water-repellent filter membrane 10 is used to ensure the purity of the final oxygen.

[0030] The seawater filtration device includes, from top to bottom, an impurity filter membrane 4, an element filter membrane 3, and a gas barrier filter membrane 2, arranged sequentially with gaps therebetween. Each of the impurity filter membrane 4, element filter membrane 3, and gas barrier filter membrane 2 is provided with a seawater filter membrane receiving ring 5 for supporting and securing the membranes. The water electrolysis device includes, from bottom to top, an anode electrode plate 17, an anode sealing layer 16, an anode catalyst layer 22, an anode diffusion layer 23, a proton exchange membrane 21, a cathode catalyst layer 20, a cathode diffusion layer 19, a cathode sealing layer 15, and a cathode electrode plate 14. An intermediate positioning ring 18 is provided on the outside of the proton exchange membrane 21. A hollow space between the anode electrode plate 17 and the anode catalyst layer forms an anode reaction chamber 205, while a hollow space between the cathode electrode plate 14 and the cathode catalyst layer 20 forms a cathode reaction chamber 206. Anode lugs 202 are provided on the sides of the anode electrode plate 17 for conducting water electrolysis, while cathode lugs 203 are provided on the sides of the cathode electrode plate 14 for conducting water electrolysis. The gas-liquid separation module includes a water-blocking filter membrane 10 and an oxygen-collecting filter membrane receiving ring 9. The water-blocking filter membrane 10 includes three membranes spaced apart from each other from top to bottom. Both ends of the three water-blocking filter membranes 10 are provided with an oxygen-collecting filter membrane receiving ring 9.

[0031] In a preferred embodiment of the present invention, a seawater filtration device is used to provide pure seawater during the water electrolysis process. The seawater filtration device includes three seawater filter membrane adapter rings 5, which are respectively mounted on the outside of an impurity filter membrane 4, an element filter membrane 3, and a gas barrier filter membrane 2. The impurity filter membrane 4, element filter membrane 3, and gas barrier filter membrane 2 are spaced apart from top to bottom to ensure that the seawater reaches the required purity after layer-by-layer filtration. The seawater filter membrane adapter rings primarily support and secure the filter membranes, preventing them from shifting during operation, thereby ensuring the stability and consistency of the filtration effect. After entering the seawater filtration chamber 102 from the water inlet 101, seawater is first filtered through the impurity filter membrane 4. The impurity filter membrane 4 effectively removes macroscopic impurity particles, such as sand and suspended matter, from the seawater, thereby purifying the seawater and protecting the normal operation of subsequent filter membranes. Next, the seawater passes through the element filter membrane 3, which is designed to filter out microscopic impurities that are harmful to the water electrolysis process, such as heavy metal ions and organic pollutants. Through this step, the purity of seawater is further improved, providing a purer raw material for the subsequent electrolysis reaction. Finally, the seawater is filtered through the gas barrier filter membrane 2. The main function of the gas barrier filter membrane 2 is to prevent the oxygen generated during the electrolysis process from escaping from the water inlet 101, ensuring the stability of the gas environment in the electrolytic cell. After completion, the seawater entering the anode reaction chamber 205 is almost pure and free of impurities, which effectively reduces the degree of corrosion of the anode electrode plate 17 during the electrolysis process and extends the service life of the electrolytic cell. Through the seawater filtration device, not only can the seawater be efficiently filtered and purified, but it can also protect the electrode plates inside the electrolytic cell, thereby improving the efficiency and stability of the water electrolysis process.

[0032] In a preferred embodiment of the present invention, a water electrolysis device is used to generate hydrogen and oxygen for trans-medium vehicles. The water electrolysis module comprises, from bottom to top, an anode electrode plate 17, an anode sealing layer 16, an anode catalyst layer 22, an anode diffusion layer 23, a proton exchange membrane 21, a cathode catalyst layer 20, a cathode diffusion layer 19, a cathode sealing layer 15, and a cathode electrode plate 14. The anode electrode plate 17, located at the lowest end, is made of a material with good electrical conductivity and corrosion resistance, such as titanium or stainless steel. It provides a reaction site and supports the attachment of the anode diffusion layer 23. The anode sealing layer 16, located above the anode electrode plate 17 and made of a polymer material resistant to acid, alkali, and high temperatures, prevents electrolyte leakage and maintains a seal between the anode electrode plate 17 and the proton exchange membrane 21. The anode catalyst layer 22, located above the anode sealing layer 16, is typically made of a porous material, such as carbon fiber cloth or carbon black. The anode diffusion layer 23 facilitates the diffusion of ions and gases in the electrolyte and improves reaction efficiency during the electrolysis process. The anode catalyst layer 22 is located above the anode diffusion layer 23 and is composed of a catalytic precious metal material (such as platinum or palladium). The anode diffusion layer 23 can reduce the activation energy of the oxidation reaction and promote the oxidation of water molecules to produce oxygen. The proton exchange membrane 21 is located between the anode diffusion layer 23 and the cathode catalyst layer 20 and is a key component of the water electrolysis device. The proton exchange membrane 21 is made of a polymer material with proton conductivity, such as a fluorinated polymer or a sulfonic acid resin. The proton exchange membrane 21 is highly selective, allowing only hydrogen ions to pass through while preventing the penetration of water molecules, ensuring effective proton transfer during the electrolysis process. The cathode catalyst layer 20 is located above the proton exchange membrane 21 and is also composed of a catalytic precious metal material. The cathode catalyst layer 20 is used to promote the reduction reaction and reduce hydrogen ions to hydrogen gas. The cathode diffusion layer 19 is located above the cathode catalyst layer 20 and is similar to the anode diffusion layer 23 and is usually composed of a porous material. The cathode diffusion layer 19 facilitates the diffusion of hydrogen gas and improves the reaction efficiency of the electrolyzer module. The cathode sealing layer 15 is located between the cathode electrode plate 14 and the cathode diffusion layer 19 and is made of a polymer material that is resistant to acid, alkali and high temperature. The cathode sealing layer 15 is used to prevent electrolyte leakage and maintain the sealing between the cathode electrode plate 14 and the proton exchange membrane 21. The cathode electrode plate 14 is located on the top of the electrolyzer module and is made of a material with good electrical conductivity and corrosion resistance, such as titanium or stainless steel. The cathode electrode plate 14 provides a reaction site and supports the attachment of the cathode catalyst layer 20. Through the combination of the above components, the water electrolysis device can realize the electrolysis process of water and produce the hydrogen and oxygen required for the cross-media vehicle.

[0033] In a preferred embodiment of the present invention, the gas-liquid separation device is used to extract pure oxygen and recover water vapor during the water electrolysis process. It includes three layers of water-blocking filter membranes 10 and three oxygen-collecting filter membrane receiving rings 9. The three layers of water-blocking filter membranes 10 are spaced apart from each other in the direction from the anode reaction chamber 205 to the oxygen outlet 301 to ensure that the oxygen reaches the required purity after being filtered layer by layer. At the same time, the water vapor left after being filtered flows back to the anode reaction chamber 205 after condensation and participates in the water electrolysis process again. The oxygen-collecting filter membrane receiving ring 9 mainly plays the role of supporting and fixing the filter membrane to ensure the stability and reliability of the water-blocking filter membrane 10 during operation. Unlike the seawater filter membrane receiving ring 5, the oxygen-collecting filter membrane receiving ring 9 needs to use materials with different properties to adapt to different working environment requirements. The purified oxygen is pressurized by an air pump and stored in a high-pressure gas tank for subsequent use. Because the proton exchange membrane 21 blocks water, a mixture of water vapor and hydrogen is not generated on the cathode side. Therefore, a gas-liquid separation module is not required; the gas can be directly collected and stored, then pressurized by an air pump and stored in a corresponding high-pressure gas tank. The gas-liquid separation device not only effectively extracts pure oxygen but also enables the recycling of water vapor, thereby improving the efficiency of the water electrolysis process.

[0034] like Figure 6-7 As shown, the air supply device is installed along the axis of the cross-medium vehicle. When the cross-medium vehicle is in a horizontal cruising state, the corresponding air supply device is in a horizontal position.

[0035] Water electrolysis generates high heat. In order to prevent the damage of high heat to the equipment, the anode side pressure plate 6 is provided with a water inlet 101 and a water outlet 102. The continuous circulation of external seawater takes away the heat, so that the equipment is in an acceptable temperature range. At the same time, the circulation of seawater can also ensure that the impurities and ion concentrations in the seawater filter chamber 102 will not accumulate. The filter housing 13 is divided into two spaces by a middle partition, one side is used for seawater filtration, and the other side is used for gas-liquid separation. Poor airtightness will cause the fluids on both sides to communicate with each other, thereby losing the filtering function. Therefore, a sealing ring gasket 8 is added to the bottom of the filter housing 13. Water electrolysis generates high heat, causing a mixed gas of oxygen and water vapor to be produced on the gas-liquid separation side. There are arrays of square holes for water vapor condensation and reflux. Two holes are provided on the top of the filter housing 13 for the filtered seawater to flow into the anode reaction chamber 205 and for the water vapor and oxygen produced by water electrolysis to flow out of the anode reaction chamber 205. The filter housing 13 and the anode electrode plate 17 are provided with a series of return pipes 204 in the form of an array of square holes near the center on the gas-liquid separation side. The return pipes have a certain slope along the radial direction. When the gas supply device is working, the water vapor generated by electrolysis on the anode side condenses and returns to the anode reaction chamber 205 through the return pipe to participate in the subsequent water electrolysis reaction. The anode electrode plate 17 and the cathode electrode plate 14 are provided with annular lugs for powering on to perform water electrolysis. The bottom anode side pressure plate 6 and the top cathode side pressure plate 1 are both provided with a water inlet 101, an oxygen outlet 301, and a hydrogen outlet 201, and at the same time withstand the local pressure brought by the connection assembly 7. The connection assembly 7 needs to be installed on the cross-media vehicle support plate during assembly to reduce the additional mounting base and corresponding connectors, which sacrifices the convenience of disassembly to a certain extent. Considering that the gas supply device is intended to have a long service life, such a compromise is feasible.

[0036] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
