Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrogen and oxygen preparation technology, specifically to a hydrogen and oxygen generator water-gas separation device. Background Technology
[0002] Hydrogen-oxygen generators typically refer to hydrogen production via water electrolysis. After producing hydrogen and oxygen through water electrolysis, gas-liquid separators (also known as steam-water separators, water-gas separators, etc.) are usually used to separate the water entrained in the gas. The main separation devices include cyclone separators, baffle separators, wire mesh demisters, condenser separators, centrifugal separators, and adsorption dryers. Efficient gas-liquid separation usually involves the combined use of multiple separation devices. For example, a condenser separator can be used to recover dripping liquid and lower the temperature of hydrogen or oxygen. Then, multi-stage separation is performed using separators such as wire mesh demisters, baffle separators, and cyclone separators to ensure the purity of hydrogen and oxygen.
[0003] Existing hydrogen-oxygen generator water-gas separation devices, in order to avoid the instability of renewable energy electrolysis leading to changes in gas rate, pressure fluctuations, pump vibrations generating pulses, etc., may cause pulsed airflow to impact the wire mesh locally. Over time, this can lead to mechanical fatigue damage to the wire mesh and affect its service life.
[0004] Existing solutions typically involve setting up buffer tanks or pressure relief valves and pressure regulation systems. Buffer tanks offer large capacity and good stability, but require high initial investment and an additional tank structure, occupying significant space. Pressure relief valves and pressure regulation valves offer excellent precision and adjustment capabilities, but both involve mechanical components. If the seals age and break, hydrogen or oxygen leaks can easily occur, posing certain safety hazards. Furthermore, pressure regulation systems rely on complex control systems to perform measurement and adjustment tasks, resulting in high investment, high energy consumption, and high maintenance costs. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a water-gas separation device for a hydrogen-oxygen generator to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-gas separation device for a hydrogen-oxygen generator, comprising a device body and an end plate. A buffer chamber is fixed inside the device body, and a diversion hole is opened on one side of the buffer chamber. A guide cylinder is fixed on the top of the buffer chamber, and a drag-reducing sleeve is connected inside the guide cylinder. A counterweight is provided inside the drag-reducing sleeve, and the counterweight is wrapped with a buffer sleeve. Limiting posts are fixed on both sides of the bottom of the end plate.
[0007] By adopting the above technical solution, when high-pressure hydrogen or oxygen flow enters the annular groove, the flow path is dispersed through multiple diversion holes, reducing the flow concentration in a single channel and thus lowering the local pressure peak. Each diversion hole acts as a throttling element; the sudden change in cross-section creates resistance as the airflow passes through, converting some kinetic energy into heat energy, effectively consuming pressure energy. Furthermore, the collision of multiple airflow streams from the diversion holes further reduces the impact force on the wire mesh. Therefore, the wire mesh is transformed from being subjected to a large localized impact to experiencing a smaller impact on the outer ring, effectively extending the service life of the wire mesh. The counterweight, made of lightweight aluminum alloy, is designed to withstand a sudden increase in pressure that can easily generate a thrust exceeding its weight, thus consuming the excess pressure and converting it into... The upward force of the counterweight increases the volume of the buffer chamber. While there is a gap between the counterweight and the guide cylinder, excess pressure can escape from the top of the guide cylinder. A limiting post restricts the counterweight from flying out of the guide cylinder, and hydrogen or oxygen remains within the main body of the device, eliminating the need for additional sealing and the risk of leakage. A buffer sleeve cushions the counterweight, preventing it from colliding with the limiting post when moving upwards or with the buffer chamber when falling; damage to these components can be easily repaired by replacing the counterweight and buffer sleeve. Furthermore, a drag-reducing sleeve prevents excessive friction between the buffer sleeve and the inner wall of the guide cylinder, which could slow down the counterweight's response and cause a safety hazard.
[0008] Furthermore, the buffer chamber is circular in shape.
[0009] By adopting the above technical solution, the pulsed gas flow of hydrogen or oxygen is evenly dispersed into multiple diversion holes through the buffer chamber, thereby dispersing pressure and reducing damage.
[0010] Furthermore, the diversion holes are provided in multiple ways, and the multiple diversion holes are distributed in a ring array.
[0011] By adopting the above technical solution, when high-pressure hydrogen or oxygen flow enters the annular groove, the flow path is dispersed through multiple diversion holes, reducing the flow concentration in a single channel and thus reducing the local pressure peak. Each diversion hole acts as a throttling element, and the airflow generates resistance due to the sudden change in cross-section, converting some kinetic energy into heat energy, effectively consuming pressure energy. Furthermore, the collision between the multiple airflows diverted by the diversion holes further reduces the impact force on the wire mesh. Therefore, the wire mesh is transformed from being subjected to a large local impact force to being subjected to a smaller impact force on the outer ring of the wire mesh, effectively extending the service life of the wire mesh.
[0012] Furthermore, the drag-reducing sleeve is coated with polytetrafluoroethylene.
[0013] By adopting the above technical solution, the friction reduction sleeve avoids the large friction between the buffer sleeve and the inner wall of the guide cylinder, which would slow down the response speed of the counterweight and cause a safety accident.
[0014] Furthermore, the buffer sleeve is made of TPU, and the buffer sleeve is slidably connected to the drag-reducing sleeve.
[0015] By adopting the above technical solution, the counterweight is buffered by the buffer sleeve, which prevents the counterweight from colliding with the limiting post when it moves upward or colliding with the buffer chamber when it falls, thus avoiding damage to the limiting post and the buffer chamber.
[0016] Furthermore, the buffer chamber, guide cylinder, and limiting column are all made of 316L stainless steel or nickel-based alloy, and the counterweight is made of aluminum alloy.
[0017] By adopting the above technical solutions, when used with hydrogen, 316L stainless steel is used, which does not react with hydrogen and avoids hydrogen embrittlement. When used with oxygen, it is made of nickel-based alloy material, which has excellent oxidation resistance. In addition, the counterweight is made of aluminum alloy material, which is relatively light. When the pressure increases suddenly, the thrust generated is greater than the weight of the counterweight, so that the excess pressure is consumed and converted into the upward force of the counterweight.
[0018] Furthermore, the buffer sleeve abuts against the limiting post.
[0019] By adopting the above technical solution, the upper part of the counterweight is limited by the limiting column, thus preventing the counterweight from flying out of the guide cylinder.
[0020] Furthermore, an air inlet pipe is fixed on one side of the main body of the device, a liquid outlet pipe is fixed at the bottom of the main body of the device, the end plate is connected to the top of the main body of the device, and a support frame is fixed in the middle of the bottom of the end plate. A wire mesh is connected inside the support frame, a limit plate is connected in the middle of the top of the end plate, a cover is connected to the top of the end plate, and an air outlet is fixed on the top of the cover.
[0021] By adopting the above technical solution, hydrogen or oxygen enters the buffer chamber through the inlet pipe, and then enters the main body of the device through the diversion hole. Subsequently, the hydrogen or oxygen rises through the wire mesh into the cap and is then sent to the next process through the outlet. The liquid trapped by the wire mesh drips downwards under the influence of gravity and is discharged through the liquid outlet pipe.
[0022] Furthermore, four of each of the guide cylinder, drag-reducing sleeve, limiting post, counterweight, and buffer sleeve are provided, and the four guide cylinders, drag-reducing sleeves, limiting posts, counterweights, and buffer sleeves are arranged in a ring array.
[0023] By adopting the above technical solution, by increasing the number of guide cylinders, resistance-reducing sleeves, limiting columns, counterweights and buffer sleeves, the cross-sectional area is increased and the pressure is dispersed, which facilitates better pressure dissipation.
[0024] Furthermore, the interior of the buffer chamber is sloped downwards.
[0025] By adopting the above technical solution, the slope at the bottom of the buffer chamber can guide the liquid trapped by the buffer chamber to the lowest diversion hole, and then the liquid flows through the diversion hole into the bottom of the device body.
[0026] In summary, the present invention has the following main advantages:
[0027] 1. This utility model, through the setting of buffer chamber and diversion holes, disperses the flow path through multiple diversion holes when high-pressure hydrogen or oxygen flow enters the annular groove, reducing the flow concentration in a single channel, thereby reducing local pressure peaks. Each diversion hole acts as a throttling element, and the resistance generated by the sudden change in cross-section when the airflow passes through it converts some kinetic energy into heat energy, effectively consuming pressure energy. Furthermore, the collision between the multiple airflows diverted by the diversion holes further reduces the impact force on the wire mesh. Therefore, the wire mesh is transformed from being subjected to a large local impact force to being subjected to a smaller impact force on the outer ring of the wire mesh, effectively extending the service life of the wire mesh. Compared with traditional buffer tanks, it has the advantages of simple structure and low cost, making it an economical and effective buffering solution.
[0028] 2. This utility model, through the design of a guide cylinder, limiting post, and counterweight, prevents a sudden increase in pressure within the buffer chamber due to the inability of the diversion orifice to discharge in time, thus avoiding a potential safety accident. The pressure increase will exceed the weight of the counterweight, causing the excess pressure to be consumed and converted into upward force on the counterweight. At this time, the volume of the buffer chamber increases. Simultaneously, there is a gap between the counterweight and the guide cylinder, allowing excess pressure to escape from the top of the guide cylinder. Furthermore, hydrogen or oxygen remains within the main body of the device, eliminating the need for additional sealing and the risk of leakage. It can assist in pressure relief when there is excessive pressure within the buffer chamber. Compared to traditional pressure relief valves, the gas remaining inside the main body of the device improves safety.
[0029] 3. This utility model uses a drag-reducing sleeve and a buffer sleeve to cushion the counterweight, preventing damage to the limit post and buffer chamber when the counterweight moves upward or falls and collides with the buffer chamber. The counterweight and buffer sleeve can be replaced in the future. At the same time, the drag-reducing sleeve prevents the counterweight from slowing down due to excessive friction between the buffer sleeve and the inner wall of the guide cylinder, thus avoiding safety accidents. This improves the stability of the structure during operation. Attached Figure Description

[0036] 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.
[0037] The embodiments of this utility model will be described below based on its overall structure.
[0038] Example 1:
[0039] A water-gas separation device for a hydrogen-oxygen generator, such as Figures 2-5As shown, the device includes a main body 1 and an end plate 4. A buffer chamber 10 is fixed inside the main body 1. The buffer chamber 10 is annular, and a flow diversion hole 11 is provided on one side of the buffer chamber 10. Multiple flow diversion holes 11 are arranged in a ring array. When high-pressure hydrogen or oxygen gas enters the annular groove, the flow path is dispersed through the multiple flow diversion holes 11, reducing flow concentration in a single channel and thus lowering local pressure peaks. Furthermore, each flow diversion hole 11 acts as a throttling element; when the airflow passes through, the sudden change in cross-section generates resistance, converting some kinetic energy into heat energy, effectively consuming pressure energy. Furthermore, the collision of multiple airflows from the diversion holes 11 further reduces the impact force on the wire mesh 6. Therefore, the impact force on the wire mesh 6 changes from being locally large to being relatively small around its outer edge, effectively extending its service life. A guide cylinder 12 is fixed to the top of the buffer chamber 10. A drag-reducing sleeve 13 is connected inside the guide cylinder 12. The drag-reducing sleeve 13 is coated with polytetrafluoroethylene (PTFE). A counterweight 15, made of aluminum alloy, is installed inside the drag-reducing sleeve 13. The counterweight 15 is wrapped with a buffer sleeve 16, made of TPU. The buffer sleeve 16 is slidably connected to the drag-reducing sleeve 13. Limiting posts 14 are fixed on both sides of the bottom of the end plate 4. The buffer chamber 10, guide cylinder 12, and limiting posts 14 are all made of 316L stainless steel or nickel-based alloy. The buffer sleeve 16 abuts against the limiting posts 14. The counterweight 15 is made of aluminum alloy and is relatively lightweight. A sudden increase in pressure can easily generate a thrust greater than the weight of the counterweight 15, causing the excess pressure to be dissipated and converted into upward force for the counterweight 15. At this time, the internal volume of the buffer chamber 10 increases. Simultaneously, there is not a complete gap between the counterweight 15 and the guide cylinder 12; a gap remains. The gap allows excess pressure to escape from the top of the guide cylinder 12, and hydrogen or oxygen remains in the main body 1 of the device without the need for additional sealing and without leakage risk; at the same time, the buffer sleeve 16 cushions the counterweight 15, preventing the counterweight 15 from colliding with the limiting post 14 when it moves upward or with the buffer chamber 10 when it falls, thus preventing damage to the limiting post 14 and the buffer chamber 10. In the future, only the counterweight 15 and the buffer sleeve 16 need to be replaced; at the same time, the drag-reducing sleeve 13 prevents the large friction between the buffer sleeve 16 and the inner wall of the guide cylinder 12 from slowing down the response speed of the counterweight 15 and causing a safety accident.
[0040] See Figure 1 , Figure 2 and Figure 5In the above embodiment, an air inlet pipe 2 is fixed on one side of the main body 1, a liquid outlet pipe 3 is fixed at the bottom of the main body 1, an end plate 4 is connected to the top of the main body 1, a support frame 5 is fixed in the middle of the bottom of the end plate 4, a wire mesh 6 is connected inside the support frame 5, a limit plate 7 is connected in the middle of the top of the end plate 4, a cover 8 is connected to the top of the end plate 4, and an air outlet 9 is fixed at the top of the cover 8. Hydrogen or oxygen enters the buffer chamber 10 through the air inlet pipe 2, and then enters the interior of the main body 1 through the diversion hole 11. Subsequently, the hydrogen or oxygen rises, passes through the wire mesh 6, enters the cover 8, and is sent to the next process through the air outlet 9. The liquid trapped by the wire mesh 6 drips downwards under the influence of gravity and is discharged through the liquid outlet pipe 3.
[0041] Example 2:
[0042] Based on the above embodiment one, the following settings are now implemented to improve the usability.
[0043] See Figure 2 and Figure 4 In the above embodiment, four guide cylinders 12, four resistance-reducing sleeves 13, four limiting posts 14, four counterweights 15 and four buffer sleeves 16 are provided. The four guide cylinders 12, four resistance-reducing sleeves 13, four limiting posts 14, four counterweights 15 and four buffer sleeves 16 are arranged in a ring array. By increasing the number of guide cylinders 12, four resistance-reducing sleeves 13, four limiting posts 14, four counterweights 15 and four buffer sleeves 16, the cross-sectional area is increased and the pressure is dispersed, which facilitates better pressure consumption.
[0044] Example 3:
[0045] Based on the above embodiment 1, in order to avoid the accumulation of liquid in the buffer chamber 10, the following settings are now adopted.
[0046] See Figure 2 and Figure 3 In the above embodiment, the lower part of the buffer chamber 10 is sloping. The slope at the lower part of the buffer chamber 10 can guide the liquid trapped by the buffer chamber to the lowest diversion hole 11, and then the liquid flows through the diversion hole 11 into the lower part of the device body 1.
[0047] The implementation principle of this utility model is as follows: First, hydrogen or oxygen enters the buffer chamber 10 through the inlet pipe 2. Then, hydrogen or oxygen enters the device body 1 through the diversion hole 11. Subsequently, hydrogen or oxygen rises through the wire mesh 6 and enters the cover 8, and is then sent to the next process through the outlet 9. The liquid trapped by the wire mesh 6 drips downward under the influence of gravity and is discharged through the liquid outlet pipe 3.
[0048] When high-pressure hydrogen or oxygen flow enters the annular groove, the flow path is dispersed through multiple diversion holes 11, reducing the flow concentration in a single channel and thus reducing the local pressure peak. Each diversion hole 11 acts as a throttling element, and the airflow generates resistance due to the sudden change in cross-section, converting some of the kinetic energy into heat energy, effectively consuming pressure energy. Furthermore, the collision between the multiple airflows diverted by the diversion holes 11 further reduces the impact force on the wire mesh 6. Therefore, the wire mesh 6 changes from being subjected to a large local impact force to being subjected to a smaller impact force on the outer ring of the wire mesh 6, effectively extending the service life of the wire mesh 6.
[0049] The counterweight 15 is made of aluminum alloy and is relatively lightweight. A sudden increase in pressure can easily generate a thrust exceeding the weight of the counterweight 15, causing the excess pressure to be dissipated and converted into upward force on the counterweight 15. At this time, the internal volume of the buffer chamber 10 increases. Simultaneously, there is a gap between the counterweight 15 and the guide cylinder 12, allowing excess pressure to escape from the top of the guide cylinder 12. At the same time, the limiting post 14 limits the upward movement of the counterweight 15, preventing it from flying out of the guide cylinder 12. Furthermore, hydrogen... The gas or oxygen is retained in the main body 1 of the device without the need for additional sealing and there is no risk of leakage. At the same time, the counterweight 15 is buffered by the buffer sleeve 16 to prevent the counterweight 15 from colliding with the limiting post 14 when it moves upward or colliding with the buffer chamber 10 when it falls. This would prevent damage to the limiting post 14 and the buffer chamber 10. In the future, only the counterweight 15 and the buffer sleeve 16 need to be replaced. At the same time, the drag-reducing sleeve 13 prevents the large friction between the buffer sleeve 16 and the inner wall of the guide cylinder 12 from slowing down the response speed of the counterweight 15 and causing a safety accident.
[0050] When it is necessary to replace the wire mesh 6, remove the bolts on the cover 8 and then remove the cover 8. After that, remove the bolts on the limit plate 7 and remove the limit plate 7. At this time, the limitation on the wire mesh 6 is ended, and the wire mesh 6 placed in the support frame 5 can be replaced directly. When it is necessary to replace the counterweight 15 and the buffer sleeve 16, remove the bolts on the end plate 4 and then remove the end plate 4. After that, insert a long pair of pliers into the guide tube 12 to take out the counterweight 15 and the buffer sleeve 16 for replacement.

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