Description

Technical Field

[0001] This utility model relates to the field of water fuels, specifically a hydrogen-oxygen-water fuel electrolysis separation device. Background Technology

[0002] Water fuel is a type of fuel obtained by electrolyzing water. Water is decomposed into a mixture of hydrogen and oxygen through electrolysis, and then reduced back to water after combustion. Compared with fossil fuels, it does not produce toxic gases such as carbon monoxide, making it a clean and recyclable energy source.

[0003] Existing hydrogen-oxygen-water fuel electrolysis separation devices typically install a diaphragm in an electrolytic cell, with a positive electrode plate and a negative electrode plate installed on both sides of the diaphragm, respectively. When energized, oxygen and hydrogen are obtained from the positive and negative electrode plates, respectively.

[0004] Regarding the aforementioned technologies, existing electrode plates are generally set vertically. After bubbles are generated on the electrode plate, due to the surface tension of the bubbles, the buoyancy generated by the air inside the bubbles is insufficient to make the bubbles float. As a result, a large number of tiny bubbles often appear on the electrode plate. Before these tiny bubbles gather into larger bubbles and float, they occupy a portion of the actual usable area of ​​the electrode plate, affecting the efficiency of water electrolysis. In summary, existing hydrogen-oxygen water fuel electrolysis devices have the problem of not being able to efficiently utilize the electrode plates. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a hydrogen-oxygen-water fuel electrolysis separation device to solve the technical problem that existing hydrogen-oxygen-water fuel electrolysis devices do not make efficient use of electrode plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen-oxygen-water fuel electrolysis separation device, comprising an electrolytic cell, wherein two insulating plates are fixedly connected to both the anode and cathode cells within the electrolytic cell. The two insulating plates are parallel to each other and form an inverted trapezoidal structure. Electrode plates parallel to the sides of the insulating plates are fixedly connected to both sides of the insulating plates. A gas guide plate is fixedly connected between the insulating plates on the opposite side of the two electrode plates. The gas guide plate is close to and parallel to the electrode plates. An arched gas storage plate is connected to the bottom end of the gas guide plate. The edge of the gas storage plate is located directly below the bottom end of the electrode plates. At least one gas guide channel is connected to both sides of the bottom end of the gas storage plate. The top end of the gas guide channel is located directly below the bottom end of the gas guide plate. A gas storage tank is fixed on the electrolytic cell. The gas storage tank is connected to a pressure relief valve. The pressure relief valve is connected to a return gas pipe, which extends to the bottom of the gas storage plate.

[0007] By adopting the above technical solution, excess gas in the gas storage tank is returned to the electrolytic cell, forming bubbles that rise from below the electrode plate to the top. During the rising process, the bubbles can quickly merge with the small bubbles formed on the electrode plate, causing the small bubbles on the electrode plate to quickly gather into large bubbles and leave the electrode plate. This effectively increases the effective usable area of ​​the electrode plate, thereby improving the efficiency of producing hydrogen and oxygen from water electrolysis.

[0008] The present invention is further configured such that two gas storage tanks are installed on the electrolytic cell, and both gas storage tanks are connected to air pumps. The air pumps are respectively connected to the positive electrode cell and the negative electrode cell of the electrolytic cell.

[0009] By adopting the above technical solution, a gas pump is used to draw the gas in the electrolytic cell into the gas storage tank.

[0010] The present invention is further configured such that the bottom end of the return gas pipe is not lower than the bottom end of the gas storage plate.

[0011] By adopting the above technical solution, the returned gas can flow out from both sides of the gas storage plate after filling the space inside the gas storage plate.

[0012] The present invention is further configured such that the edge of the insulating plate extends outwards and beyond the mounting position of the electrode plate.

[0013] By adopting the above technical solution, the bubbles generated on the outer side of the electrode plate can float upwards along the outer surface of the electrode plate.

[0014] The present invention is further configured such that the electrode plates between the insulating plates are interconnected by a conductive component, and the conductive component extends upward through the electrolytic cell.

[0015] By adopting the above technical solution, conductive components are used to connect the two electrode plates in the anode pool or cathode pool.

[0016] The present invention is further configured such that the width of the gas storage plate is equal to the spacing of the insulating plates.

[0017] By adopting the above technical solution, the gas below the gas storage plate can smoothly generate bubbles from both sides and rise to the surface.

[0018] The present invention is further configured such that the bottom opening of the air guide channel is flush with the bottom of the air storage plate.

[0019] By adopting the above technical solution, the bubbles overflowing from both sides of the gas storage plate flow along the gas guiding channel and float out from the top of the gas guiding channel.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention uses an inclined electrode plate with a gas return component below it. This allows excess gas in the gas storage tank to return to the electrolytic cell, forming bubbles that rise from below the electrode plate. As these bubbles rise, they quickly merge with smaller bubbles formed on the electrode plate, causing them to rapidly coalesce into larger bubbles before leaving the electrode plate. This effectively increases the usable area of ​​the electrode plate, thereby improving the efficiency of hydrogen and oxygen production from water electrolysis. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1

[0033] A hydrogen-oxygen-water fuel electrolysis separation device, such as Figure 1-7As shown, the electrolytic cell 1 includes a cathode cell and an anode cell, with a diaphragm between them. Two insulating plates 2 are fixedly connected to both the anode and cathode cells in the electrolytic cell 1. These insulating plates 2 are parallel to each other and form an inverted trapezoidal structure. Electrode plates 3, parallel to the sides of the insulating plates 2, are fixedly connected to both sides of the insulating plates 2. Gas guide plates 4 are fixedly connected to the insulating plates 2 on the opposite side of the two electrode plates 3. The gas guide plates 4 are close to the electrode plates 3 and maintain a certain distance from them. Specifically, the gas guide plate 4 and the electrode plate 3 are parallel to each other, with a distance of no more than 5 mm. The bottom end of the gas guide plate 4 is connected to an arched gas storage plate 5. The edge of the gas storage plate 5 is located directly below the bottom end of the electrode plate 3. At least one gas guide channel 6 is connected to both sides of the bottom end of the gas storage plate 5. The top end of the gas guide channel 6 is located directly below the bottom end of the gas guide plate 4. A gas storage tank 9 is fixed on the electrolytic cell 1. The gas storage tank 9 is connected to a pressure relief valve 8. The pressure relief valve 8 is connected to a return gas pipe 7. The return gas pipe 7 extends to the bottom of the gas storage plate 5.

[0034] Please see Figure 2-7 The bottom end of the return gas pipe 7 is not lower than the bottom end of the gas storage plate 5 to prevent the gas flowing out from the return gas pipe 7 from flowing out from both ends of the insulating plate 2, so that the returned gas can flow out from both sides of the gas storage plate 5 after filling the internal space of the gas storage plate 5. The bottom opening of the gas guide channel 6 is flush with the bottom end of the gas storage plate 5, so that the bubbles overflowing from both sides of the gas storage plate 5 flow along the gas guide channel 6 and float out from the top of the gas guide channel 6, adhering to the gas guide plate 4 and floating upward. While adhering to the gas guide plate 4, due to the surface tension of the liquid, the bubbles also adhere to the inner surface of the electrode plate 3 while adhering to the gas guide plate 4, floating upward between the electrode plate 3 and the gas guide plate 4, and collecting the small bubbles generated on the electrode plate 3 along the way. The electrode plates 3 between the insulating plates 2 are connected to each other by a conductive component 11. The conductive component 11 extends upward and passes through the electrolytic cell 1, and the two electrode plates 3 in the anode cell or cathode cell are connected by the conductive component 11.

[0035] Please see Figure 4-7 The edge of the insulating plate 2 extends outwards and beyond the installation position of the electrode plate 3. The edge of the insulating plate 2 extends downwards and beyond the bottom end of the gas storage plate 5. After the edge of the insulating plate 2 extends beyond the installation position of the electrode plate 3, it guides the bubbles generated on the outside of the electrode plate 3, allowing the bubbles generated on the outside of the electrode plate 3 to float upwards along the outer surface of the electrode plate 3. The width of the gas storage plate 5 is equal to the spacing of the insulating plates 2, allowing the gas below the gas storage plate 5 to smoothly generate bubbles from both sides and float upwards.

[0036] Example 2

[0037] A hydrogen-oxygen-water fuel electrolysis separation device, such as Figure 1-7As shown, based on Embodiment 1, the difference is that two gas storage tanks 9 are installed on the electrolytic cell 1. Both gas storage tanks 9 are connected to air pumps 10. The air extraction pipes of the two air pumps 10 are respectively connected to the positive electrode cell and the negative electrode cell of the electrolytic cell 1. The air pumps 10 draw the gas in the electrolytic cell 1 into the gas storage tanks 9, so that the hydrogen or oxygen in the gas storage tanks 9 maintains a certain pressure, effectively preventing the external gas from flowing back into the gas storage tanks 9 along the pipes. After the pressure in the gas storage tanks 9 rises to the threshold, the excess gas will flow back into the corresponding anode cell or cathode cell in the electrolytic cell 1 through the pressure relief valve 8.

[0038] The working principle of this utility model is as follows: After the electrolytic cell 1 is powered on, bubbles are generated on the electrode plate 3. After the pressure in the gas storage tank 9 rises to exceed the pressure preset by the pressure relief valve 8, the gas in the gas storage tank 9 flows along the return gas pipe 7 to the space below the gas storage plate 5. After discharging the water below the gas storage plate 5, the space below the gas storage plate 5 is filled with gas. The return gas pipe 7 continues to inject gas into the space below the gas storage plate 5. Excess gas in the gas storage plate 5 overflows from both sides to form bubbles. Some bubbles rise directly, adhering to the outer surface of the electrode plate 3 and merging with small bubbles during the ascent. Other bubbles rise along the gas guide channel 6 to the space between the electrode plate 3 and the gas guide plate 4, adhering to both and rising. During the ascent, they also merge with the small bubbles formed on the electrode plate 3, allowing the electrode plate 3 to maintain as much contact area with water as possible, thereby effectively improving the electrolysis efficiency of the electrolysis device.
