Description

Technical Field

[0001] This utility model relates to the field of electrolytic hydrogen production technology, specifically to a gas-liquid separator and an electrolysis device. Background Technology

[0002] Gas-liquid separators are commonly used in processes to purify gases containing liquids. In existing technologies, the injection port of the gas-liquid mixture is usually placed at the bottom, and the first outlet is placed at the top. This design utilizes the property that gases rise due to their lower gravity and liquids sink due to their higher gravity to achieve gas-liquid separation. However, this design has limited separation efficiency. After the gas-liquid mixture is injected, it enters the bottom of the separator. Some of the gas in the mixture is obstructed by the liquid and cannot rise smoothly and detach from the upper liquid surface. The rising gas also contains a small amount of liquid, resulting in poor gas-liquid separation. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] It should be noted that, Figure 3 and Figure 4 The arrows in the diagram indicate the direction of gas flow.

[0033] refer to Figures 1 to 4According to a first aspect embodiment of the present invention, a gas-liquid separator 100 includes a main body 101 and a waterproof and breathable membrane 201. The main body 101 has a cavity 301 and an inlet 102 and a first outlet 103 connected to the cavity 301. The waterproof and breathable membrane 201 is disposed within the cavity 301, dividing the cavity 301 into a mixing zone 302 and a gas zone 303. The inlet 102 connects to the mixing zone 302 and is used to introduce a gas-liquid mixture. The first outlet 103 connects to the gas zone 303. The connection between the inlet 102 and the mixing zone 302 is located at the top of the cavity 301. At least a portion of the waterproof and breathable membrane 201 is arranged vertically, and the connection between the inlet 102 and the mixing zone 302 is higher than the bottom of the vertically arranged portion of the waterproof and breathable membrane 201. The injection port 102 is positioned higher than the bottom of the vertically positioned portion of the waterproof and breathable membrane 201. This allows the gas and liquid mixture to separate during its descent due to the difference in gravity between the gas and liquid. The waterproof and breathable membrane 201 can effectively filter out the small amount of liquid contained in the gas moving from the mixing zone 302 to the gas zone 303. Furthermore, the vertically positioned portion of the waterproof and breathable membrane 201 can perform gas-liquid separation on the gas separated during its descent as it moves to the gas zone 303, thus improving the gas-liquid separation effect.

[0034] It should be noted that the reference Figure 1 and Figure 2 In some embodiments of this invention, the injection port 102 is located at the top of the main body 101, allowing the gas-liquid mixture to fall from a higher position, thus improving the separation effect by gravity. Due to the property that gas rises and liquid falls, the waterproof and breathable membrane 201 is typically positioned higher to achieve better gas-liquid separation. Therefore, in this embodiment, the injection port 102 is positioned higher than the bottom of the waterproof and breathable membrane 201, which, compared to the prior art where it is positioned at the bottom, already provides a better gas-liquid separation effect. Positioning the injection port 102 at the top of the main body 101 is a preferred embodiment. The waterproof and breathable membrane 201 has a large number of micropores, allowing gas to easily pass through, while liquid water droplets, larger than the diameter of the micropores, cannot pass through them. This gives the waterproof and breathable membrane 201 both waterproof and breathable functions, effectively improving the purity of the filtered gas.

[0035] It should be noted that the reference Figures 1 to 3 In some embodiments of this utility model, the gas-liquid separator 100 is arranged vertically; in other embodiments, the gas-liquid separator 100 can be placed horizontally, that is... Figure 1The gas-liquid separator 100 rotates, and the drain pipe 104, injection port 102 and first gas outlet 103 can also be adjusted accordingly. Since the actual injection process of the gas-liquid mixture will cause fluctuations, horizontal placement can also achieve the effect of gas-liquid separation. The main body 101 and the gas storage bottle 105 can be placed at different angles according to production needs or working environment.

[0036] Meanwhile, it should be noted that the gas-liquid separation in the prior art often adopts a purely mechanical labyrinth barrier structure, which uses the difference in adhesion and fluidity of gas and liquid to separate them. This method has low separation efficiency. The present invention uses a waterproof and breathable membrane 201 to complete gas-liquid separation in a shorter time, improve production efficiency, and has a more compact internal structure and occupies less space.

[0037] refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this utility model, the waterproof and breathable membrane 201 includes a first filter section 401 and a second filter section 402. The second filter section 402 is arranged along a horizontal plane, and the first filter section 401 surrounds the second filter section 402 and is arranged in a vertical direction. The bottom end of the first filter section 401 is connected to the outer peripheral surface of the second filter section 402. The gas zone 303 is located above the second filter section 402 and is surrounded by the first filter section 401. The mixing zone 302 is arranged around the second filter section 402 and the first filter section 401. Since gases typically rise while liquids sink, the horizontally arranged second filter section 402 can effectively filter the liquid in the rising gas that carries some liquid, allowing the gas that continues to rise after passing through the waterproof and breathable membrane 201 to enter the gas zone 303. The vertically arranged first filter section 401 provides a filtration environment for the gas separated from the mixture falling from the injection port 102. At the same time, after the gas-liquid mixture is injected, there will be a lot of gas in the cavity 301. The first filter section 401 can also increase the filtration area and improve the filtration efficiency.

[0038] It should be noted that the reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this invention, the second filter section 402 is circular, with its center coinciding with the central axis of the main body 101. Two injection ports 102 are symmetrically designed along the central axis of the cavity 301. This design improves the injection efficiency of the gas-liquid mixture, increases the density of the gas-liquid mixture floating within the cavity 301, increases the amount of gas passing through the waterproof and breathable membrane 201, and improves the efficiency of gas-liquid separation. Central symmetry ensures that gas is filtered as evenly as possible in all directions of the first filter section 401, while reducing gas fluctuations after filtration. In some embodiments of this invention, multiple injection ports 102 can also be provided according to production needs.

[0039] refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this utility model, the main body 101 includes an inner core 304 and an outer shell 202 connected to each other. The outer shell 202 has a cavity 301. The inner core 304 includes a first part 203 and a second part 204 that are detachably connected. The first part 203 is detachably connected to the outer shell 202 and covers the opening of the cavity 301. The second part 204 is located inside the cavity 301. A portion of the waterproof and breathable membrane 201 is sandwiched between the first part 203 and the second part 204. The waterproof and breathable membrane 201 has relatively light and thin physical properties. Therefore, designing the inner core 304 as two detachable parts and sandwiching the waterproof and breathable membrane 201 therein can improve the stability of the waterproof and breathable membrane 201 during operation. Furthermore, since the second part 204 is detachably connected to the first part 203, replacing the waterproof and breathable membrane 201 becomes convenient.

[0040] refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this utility model, the first part 203 has a first through hole 403 in the horizontal direction, the second part 204 has a second through hole 404, the first through hole 403 and the second through hole 404 are aligned, a part of the first filter part 401 is located between the first through hole 403 and the second through hole 404, the first part 203 has a first channel 405 in the vertical direction, the first channel 405 is connected to the first through hole 403 and the first air outlet 103, the second part 204 has a second channel 406, the second channel 406 is connected to the injection port 102, the second channel 406 is aligned with the first channel 405, and a part of the second filter part 402 is located between the first channel 405 and the second channel 406. The horizontally opened first through hole 403 and second through hole 404 can clamp the first filter part 401, while the second through hole 404 provides a path for the horizontally moving gas-liquid mixture to flow to the waterproof and breathable membrane 201, and the first through hole 403 provides a path for the filtered gas to flow to the first air outlet 103. In this way, the gas-liquid mixture injected from the injection port 102 passes through the second through hole 404, the first filter part 401 and the first through hole 403 in sequence, and then achieves gas-liquid separation and is discharged from the first air outlet 103. Similarly, the vertically arranged first channel 405 and second channel 406, while clamping part of the second filter section 402, provide a path for the vertically moving gas-liquid mixture to flow to the waterproof and breathable membrane 201, and the first channel 405 provides a path for the filtered gas to flow to the first air outlet 103. In this way, the gas-liquid mixture injected from the injection port 102 passes through the second channel 406, the second filter section 402 and the first channel 405 in sequence to achieve gas-liquid separation and be discharged from the first air outlet 103.

[0041] It should be noted that the reference Figure 2 and Figure 4 The second channel 406 and the injection port 102 are connected because they are both in the mixing zone 302. The second channel 406 and the second through hole 404, the first channel 405 and the first through hole 403 are also connected to each other.

[0042] It should be noted that in some embodiments of this utility model, the first through hole 403 and the second through hole 404 do not need to be set completely horizontally, and the first channel 405 and the second channel 406 do not need to be set completely vertically. This is a preferred embodiment of this utility model considering factors such as processing and filtration effect. A hole is opened in the inner core 304 to hold the waterproof and breathable membrane 201, and the holes on both sides of the waterproof and breathable membrane 201 are respectively connected to the injection port 102 and the first air outlet 103.

[0043] refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this utility model, the waterproof and breathable membrane 201 further includes a pressing part 407. The pressing part 407 is arranged horizontally and is annular. The inner ring of the pressing part 407 is connected to the top end of the first filter part 401. The pressing part 407 is sandwiched between the first part 203 and the second part 204. Since the first filter part 401 is vertically arranged, it is easy to slide downward during use. The annular pressing part 407 is provided at the top end of the first filter part 401, and the first part 203 is covered above the pressing part 407 and the second part 204 is placed below it. This allows the two components of the inner core 304 to better clamp the waterproof and breathable membrane 201, improving the stability of the waterproof and breathable membrane 201 during use.

[0044] refer to Figure 3 and Figure 4 In some embodiments of this utility model, the first part 203 has a first channel 405 in the vertical direction, which is connected to the first air outlet 103. The second part 204 has a second channel 406, which is connected to the injection port 102. The second channel 406 is aligned with the first channel 405. A part of the second filter part 402 is located between the first channel 405 and the second channel 406. The second part 204 is provided with a corner part 408. The corner part 408 and the first part 203 together clamp the connection between the first filter part 401 and the second filter part 402. The part of the second filter part 402 that is clamped in the corner part 408 and the pressing part 407 are both provided with sealing rings 205. The first part 203 and the second part 204 together clamp the sealing rings 205 so that the sealing rings 205 press the waterproof and breathable membrane 201. The corner portion 408 is also to prevent the waterproof and breathable membrane 201 from loosening or falling off during use, thereby improving its stability. Since the waterproof and breathable membrane 201 is a thin membrane, the sealing ring 205 is provided at the location of the pressing portion 407 and the second filter portion 402 to facilitate the first part 203 and the second part 204 to better press the waterproof and breathable membrane 201, while also preventing the gas-liquid mixture from entering the gap between the first part 203 and the second part 204.

[0045] refer to Figure 5 and Figure 6 In some embodiments of this utility model, viewed vertically, the waterproof and breathable membrane 201 includes a plurality of interconnected teeth 501 arranged circumferentially, each tooth 501 including two intersecting filter portions 601 with an acute angle between them. This design allows the waterproof and breathable membrane 201 to have a larger filtration area, improves space utilization, and enhances the gas-liquid separation effect. Meanwhile, referring to... Figure 7In some embodiments of this utility model, the waterproof and breathable membrane 201 can also be sandwiched between the first part 203 and the second part 204, and the gap between the first part 203 and the second part 204 can be enlarged accordingly.

[0046] It should be noted that the reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the gas-liquid separator 100 further includes a drain pipe 104, which is disposed at the bottom end of the main body 101 and communicates with the cavity 301. After gas-liquid separation for a period of time, excessive liquid will accumulate in the cavity 301. The drain pipe 104 is provided to discharge the accumulated liquid, preventing excessive liquid accumulation from affecting the subsequent injection of the gas-liquid mixture. At the same time, excessive liquid will also dissolve some of the gas.

[0047] It should be noted that in some embodiments of this utility model, the drain pipe 104 is connected to a drain valve, which can better control the discharge of liquid. Furthermore, the gas-liquid separator 100 is also equipped with a liquid level sensor, which is used to detect the liquid level in the cavity 301, thereby enabling a more intuitive connection to the internal condition of the cavity 301 and to carry out a quantitative and controllable liquid discharge process.

[0048] It should be noted that the reference Figure 1 and Figure 3 In some embodiments of this utility model, the bottom of the cavity 301 is designed as an inverted cone shape, which facilitates the accumulation of liquid at the lowest point in the middle after it falls, making it convenient for the drain pipe 104 to drain the liquid.

[0049] refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the gas-liquid separator 100 further includes a gas storage bottle 105, which includes an inlet 106 and a second outlet 107. The inlet 106 is connected to the first outlet 103, and the second outlet 107 is used to discharge gas. When the drain pipe 104 discharges liquid, it causes a change in the volume inside the cavity 301, resulting in large fluctuations in the gas. Therefore, the gas storage bottle 105 is connected to the first outlet 103 to prevent the gas from flowing directly into subsequent devices. Instead, the gas first enters the gas storage bottle 105 for pressure maintenance, allowing the gas to reach a stable airflow state before entering other devices, thus improving the stability of the entire system operation.

[0050] refer to Figure 1 and Figure 2In some embodiments of this utility model, the gas-liquid separator 100 further includes a fixing frame, which includes a first ring 206 and a second ring 207 fixed to each other. The first ring 206 is fitted around the outer periphery of the main body 101, and the second ring 207 is fitted around the outer periphery of the gas storage cylinder 105. This design can improve the relative stability between the main body 101 and the gas storage cylinder 105, ensuring that unnecessary fluctuations are reduced during the process of gas flowing from the first outlet 103 into the inlet 106, thus facilitating the stability of the subsequent gas flow. It should be noted that in some embodiments of this utility model, the main body 101 and the gas storage cylinder 105 can be fixed to each other by the fixing frame, or they can be designed as an integrated unit, or they can be separated and used separately.

[0051] An electrolysis apparatus according to a second aspect of the present invention includes an electrolytic cell and a gas-liquid separator 100 according to any one of the first aspect embodiments. The electrolytic cell is used to electrolyze water to produce hydrogen and oxygen. The electrolytic cell is provided with a hydrogen outlet, and an injection port 102 is connected to the hydrogen outlet. The electrolytic cell decomposes water to produce hydrogen and oxygen. Therefore, the hydrogen at the hydrogen outlet contains a certain amount of water vapor. After connecting the injection port 102 and the hydrogen outlet, the injection port 102 is positioned higher than the bottom of the vertically positioned part of the waterproof and breathable membrane 201. During the fall of the hydrogen-water mixture, due to the difference in gravity between the hydrogen and water vapor, some hydrogen and water vapor will separate. The waterproof and breathable membrane 201 can effectively filter out the small amount of water contained in the hydrogen moving from the mixing zone 302 to the gas zone 303. Furthermore, the vertically positioned part of the waterproof and breathable membrane 201 can perform gas-liquid separation on the hydrogen separated during the fall as it moves to the gas zone 303, improving the gas-liquid separation effect and thus improving the purity of the hydrogen produced by the electrolytic device of this embodiment.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
