Abstract
Description
Technical Field
[0001] This application relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separator and a water electrolysis hydrogen production system. Background Technology
[0002] In some processes, such as hydrogen production via water electrolysis, the resulting gas-liquid mixture needs to be separated to remove liquid components from the gas and obtain a pure gaseous product with a low liquid content. Gas-liquid separators are typically used for this separation process. However, in related technologies, the gas-liquid separation efficiency of these separators is relatively low, resulting in the outlet gas still containing a significant amount of droplets or mist, leading to a high liquid content that does not meet the requirements of the process. Utility Model Content
[0003] The main purpose of this application is to propose a gas-liquid separator and a water electrolysis hydrogen production system, which aims to improve the gas-liquid separation efficiency of the gas-liquid separator.
[0004] To achieve the above objectives, the gas-liquid separator proposed in this application includes: The casing has a mixture inlet and an exhaust outlet; and Multiple cylinders are installed inside the housing. The multiple cylinders include a first cylinder and a second cylinder. The first cylinder is provided with a first flow guiding channel. The second cylinder is spaced out and sleeved on the outside of the first cylinder. At least one flow deflection channel is formed between the first cylinder and the second cylinder. The second cylinder is provided with a flow guide inlet, and the mixture inlet is connected to the baffle channel through the flow guide inlet; One end of the first flow guiding channel is connected to the exhaust port through a flow guiding outlet, and the other end is connected to the baffle channel through an air connection port on the first cylinder. The flow guiding direction of the first flow guiding channel is opposite to the flow guiding direction of the adjacent baffle channel.
[0005] In one embodiment, the plurality of cylinders further includes at least one third cylinder disposed between the first cylinder and the second cylinder to form a plurality of the baffle channels between the first cylinder and the second cylinder. The flow directions of two adjacent baffle channels are opposite and they are connected through an air connection port on the third cylinder.
[0006] In one embodiment, the flow area of the flow inlet and / or any of the gas-connected ports on the cylinder is 1.2 to 3 times the flow area of the mixture inlet.
[0007] In one embodiment, the flow direction of the baffle channel is parallel to the axial direction of the cylinder.
[0008] In one embodiment, the flow direction of the baffle channel is either spiral upward or spiral downward.
[0009] In one embodiment, the flow inlet is disposed away from the mixture inlet to form a second flow channel between the second cylinder and the shell, the flow direction of the second flow channel being opposite to the flow direction of the adjacent baffle channel.
[0010] In one embodiment, the mixture inlet is located at the lower part of the shell, the mixture inlet is configured in a downward guiding direction, and the guiding inlet is located at the upper part of the second cylinder.
[0011] In one embodiment, a first separator is installed in the first flow channel.
[0012] In one embodiment, a second separator is installed in the upward-directing deflector channel.
[0013] In one embodiment, the housing is further provided with a first support member and a second support member, at least one of the first support member and the second support member is fixed to the housing, the first support member is spaced apart on the upper side of the second support member, both ends of each cylinder are respectively connected to the first support member and the second support member, the guide outlet is provided on the first support member, the second support member is provided with a drain port, and the baffle channel and the first guide channel are both connected to the drain port.
[0014] In one embodiment, the second support member has a drain port between every two adjacent cylinders.
[0015] In one embodiment, at least one of the cylinders has a liquid connection port at its bottom, and the gas connection port at the bottom of the cylinder is higher than the liquid connection port.
[0016] In one embodiment, the second support member is configured as a downwardly protruding arc-shaped structure.
[0017] This application also proposes a water electrolysis hydrogen production system, which includes an electrolyzer and the aforementioned gas-liquid separator, wherein the electrolysis product outlet of the electrolyzer is connected to the mixture inlet.
[0018] In this application's technical solution, the gas-liquid mixture enters the shell through the mixture inlet, first passing through the guide inlet into the baffle channel, then into the first guide channel, and finally flowing from the guide outlet to the exhaust port. Because the guide direction of the first guide channel is opposite to that of the adjacent baffle channel, the gas-liquid mixture undergoes at least one turn within the shell, with a significant turning amplitude. This helps to extend the flow path and residence time of the gas-liquid mixture within the shell, thereby fully utilizing gravity to achieve droplet sedimentation. Furthermore, due to the significant difference in mass and inertia between the gas and droplets, the droplets easily detach from the gas during the gas-liquid mixture's turning, thus enhancing the gas-liquid separation effect and improving the gas-liquid separation efficiency of the gas-liquid separator.

[0026] This application proposes a gas-liquid separator.
[0027] Please see Figures 1 to 4In one embodiment of this application, the gas-liquid separator includes a housing 100, which has a mixture inlet 101 and an exhaust port 102. Multiple cylinders 200, i.e., at least two cylinders 200, are installed inside the housing 100. The multiple cylinders 200 include a first cylinder 210 and a second cylinder 220. The first cylinder 210 has a first flow channel 201, and the second cylinders 220 are spaced apart from the first cylinder 210. At least one flow-deflecting channel 203 is formed between them. The second cylinder 220 is provided with a flow-guiding inlet 221. The mixture inlet 101 is connected to the flow-deflecting channel 203 through the flow-guiding inlet 221. One end of the first flow-guiding channel 201 is connected to the exhaust port 102 through the flow-guiding outlet 411, and the other end is connected to the flow-deflecting channel 203 through the gas connection port 204 on the first cylinder 210. The flow direction of the first flow-guiding channel 201 is opposite to the flow direction of the adjacent flow-deflecting channel 203.
[0028] In the technical solution of this application, the gas-liquid mixture enters the housing 100 through the mixture inlet 101, first enters the baffle channel 203 through the guide inlet 221, then enters the first guide channel 201, and then flows from the guide outlet 411 to the exhaust port 102. Since the guide direction of the first guide channel 201 is opposite to that of the adjacent baffle channel 203, the gas-liquid mixture undergoes at least one turn within the housing 100, and the turn is significant. This helps to extend the flow path and residence time of the gas-liquid mixture within the housing 100, thereby fully utilizing gravity to achieve droplet sedimentation. Furthermore, due to the significant difference in mass and inertia between the gas and the droplets, the droplets easily detach from the gas during the turn, thus enhancing the gas-liquid separation effect and improving the gas-liquid separation efficiency of the gas-liquid separator.
[0029] In one implementation, please refer to Figures 2 to 4The plurality of cylinders 200 also includes at least one third cylinder 230, which is disposed between the first cylinder 210 and the second cylinder 220 to form multiple baffle channels 203 between the first cylinder 210 and the second cylinder 220. The flow directions of two adjacent baffle channels 203 are opposite and they are connected through an air connection port 204 on the third cylinder 230. In this way, the flow path and residence time of the gas-liquid mixture in the shell 100 can be further extended, and the number of turns of the gas-liquid mixture can be increased. Specifically, after the gas-liquid mixture passes through the first baffle channel 203, it needs to enter the next baffle channel 203 through the air connection port 204 on the third cylinder 230. The flow directions of adjacent baffle channels 203 are opposite to each other, forming a continuous "serpentine" flow path, which increases the travel length and the number of changes in flow direction of the airflow inside the shell 100. Each change in flow direction strengthens the tendency of droplets to detach from the gas phase due to inertia. Simultaneously, the longer flow path provides more time for droplets to settle under gravity, allowing fine droplets to gradually coalesce and slide down the inner wall of the cylinder 200, thus achieving staged and efficient gas-liquid separation. In other embodiments, the third cylinder 230 may not be provided; instead, a baffle channel 203 may be formed only between the first cylinder 210 and the second cylinder 220.
[0030] In one embodiment, the flow area of the guide inlet 221 and / or the gas-connecting port 204 on any of the cylinders 200 is 1.2 to 3 times the flow area of the mixture inlet 101. That is, the area ratio of the flow area of at least one of the guide inlet 221 and the gas-connecting port 204 on each cylinder 200 to the flow area of the mixture inlet 101 is 1.2 to 3. When there are multiple guide inlets 221 or multiple gas-connecting ports 204 distributed on a cylinder 200, the ratio should be based on the equivalent flow area of the multiple guide inlets 221 as a whole or the equivalent flow area of the multiple gas-connecting ports 204 as a whole. By controlling this area ratio, the flow velocity of the gas-liquid mixture in the second cylinder 220 can be controlled. When this area ratio is within the range of this embodiment, the flow velocity of the gas-liquid mixture after entering the baffle channel 203 can be slowed down, avoiding the difficulty of droplet settling or the re-entrainment of captured droplets due to excessive flow velocity. A lower flow rate not only facilitates the gravity settling mechanism but also reduces the shearing effect of the airflow on the liquid film adhering to the inner wall of the cylinder 200, preventing the liquid film from rupturing and forming secondary atomization. Simultaneously, a reasonable flow area ratio can achieve a good balance between flow rate and separation efficiency without significantly increasing the equipment volume, thereby improving the processing capacity per unit space. Specifically, the aforementioned flow area ratio can be 1.2, 1.5, 2, 2.5, or 3. In other embodiments, this area ratio can also be 0.8, 1, 3.5, or 4, etc.
[0031] In one implementation, please refer to Figures 1 to 3 The flow direction of the baffle channel 203 is parallel to the axis of the cylinder 200. That is, the flow direction of the baffle channel 203 is vertically upward or vertically downward. This flow direction design is beneficial for constructing a longer flow path in a limited space, improving the space utilization rate within the shell 100, and also facilitates the natural convergence of liquid to the bottom drainage area under the action of gravity, avoiding liquid accumulation.
[0032] In one implementation, please refer to Figure 4 and Figure 5 The flow direction of the baffle channel 203 is either spiral upward or spiral downward. In this way, the gas-liquid mixture can undergo spiral flow within the baffle channel 203, which not only prolongs the actual flow path but also introduces a certain centrifugal effect. This makes it easier for denser droplets to migrate and adhere to the outer wall of the channel under the action of centrifugal force, thereby further enhancing the gas-liquid separation effect.
[0033] It should be noted that the flow direction of the first flow guide channel 201 is opposite to that of the adjacent baffle channel 203 in the vertical direction; that is, one has an upward flow direction, and the other has a downward flow direction. For example, when the flow direction of the first flow guide channel 201 is configured to be vertically upward, the flow direction of its adjacent baffle channel 203 can be configured to be either vertically downward or spirally downward. Specifically, the exhaust port 102 is located at the top of the housing 100, the flow direction of the first flow guide channel 201 is vertically upward, the flow outlet 411 is located at the top of the first cylinder 210, and the first cylinder 210 has an air connection port 204 at the bottom that connects to the adjacent baffle channel 203.
[0034] In addition, when setting up multiple deflection channels 203, each deflection channel 203 can be uniformly configured with a vertical flow direction, or uniformly configured with a spiral flow direction. Alternatively, some deflection channels 203 can be configured with a vertical flow direction, while the remaining deflection channels 203 can be configured with a spiral flow direction.
[0035] In one implementation, please refer to Figures 1 to 4 A first separator 310 is installed within the first flow channel 201. This first separator 310 can perform fine demisting on the airflow entering the first flow channel 201, capturing residual fine droplets, and is particularly suitable for process scenarios with high requirements for the purity of the outlet gas. Specifically, the first separator 310 can be a wire mesh demister, a corrugated plate demister, or other functional components with high specific surface area and good wettability, and can achieve efficient liquid removal through interception, inertial collision, and coalescence mechanisms.
[0036] Further, please refer to Figure 2A second separator 320 is installed within the upward-directing baffle channel 203. This second separator intervenes in the droplet interception and coalescence process during the primary separation stage, forming a multi-stage synergistic separation mechanism. This significantly reduces the demisting load of the first separator 310 and improves the overall system's fault tolerance and stability. Specifically, the second separator 320 can be configured as a Pall ring or packing. Installed within the upward-directing baffle channel 203, droplets are captured and coalesced on the surface of the second separator 320, then converge and discharge downwards along the wall under gravity, while the airflow flows upwards. Because the airflow direction is opposite to the liquid phase discharge direction, it effectively avoids shearing and entrainment of the coalesced liquid during downward airflow, preventing the separated liquid phase from being re-entrained into the gas phase and causing secondary entrainment, thus ensuring the continuity and efficiency of the separation process.
[0037] In other embodiments, it may also be as follows Figure 1 , Figure 3 and Figure 4 As shown, only the first separator 310 is set, and the second separator 320 is not set, or neither is set. The specific choice can be made based on the actual separation requirements and economic considerations.
[0038] In one implementation, please refer to Figures 1 to 4 The flow inlet 221 is positioned away from the mixture inlet 101 to form a second flow channel 202 between the second cylinder 220 and the shell 100. The flow direction of the second flow channel 202 is opposite to that of the adjacent deflection channel 203. This adds a turning point when the gas-liquid mixture enters the first cylinder 210 through the liquid inlet, and extends the flow path of the gas-liquid mixture outside the second cylinder 220, allowing for preliminary separation of the gas-liquid mixture before it enters the second cylinder 220. This pre-buffering and pre-separation design helps to achieve uniform airflow distribution, reduces inlet disturbance, and improves the gas-liquid separation efficiency in subsequent channels. In other embodiments, the flow inlet 221 may also be located closer to the mixture inlet 101.
[0039] In one implementation, please refer to Figures 1 to 4 The mixture inlet 101 is located at the lower part of the shell 100 and is configured to flow downwards. The guide inlet 221 is located at the upper part of the second cylinder 220. Thus, the gas-liquid mixture enters the shell 100 downwards from the mixture inlet 101, undergoes a first turn, flows upwards to the guide inlet 221, and then undergoes another turn, flowing downwards along the first baffle channel 203. This ensures good initial separation of the gas-liquid mixture before it enters the second cylinder 220. In other embodiments, the mixture inlet 101 may be located at the upper part of the shell 100, and the guide inlet 221 at the lower part of the second cylinder 220.
[0040] In one implementation, please refer to Figures 1 to 4 The housing 100 also includes a first support member 410 and a second support member 420. At least one of the first support member 410 and the second support member 420 is fixed to the housing 100. The first support member 410 is spaced apart above the second support member 420. Both ends of each cylinder 200 are respectively connected to the first support member 410 and the second support member 420. The flow outlet 411 is located on the first support member 410. Please refer to [further details]. Figure 5 The second support member 420 is provided with a drain port 421, and the baffle channel 203 and the first guide channel 201 are both connected to the drain port 421.
[0041] In this way, the cylinders 200 can be connected as a whole by the first support member 410 and the second support member 420. Simultaneously, by fixing at least one of the first support member 410 and the second support member 420 to the housing 100, the integrated structure can also be fixed to the housing 100, thereby ensuring the structural stability of the baffle cylinder 200 assembly. Specifically, both the first support member 410 and the second support member 420 can be fixed to the housing 100, or one of the first support member 410 and the second support member 420 can be spaced apart from the housing 100, while the other is fixed to the housing 100. In other embodiments, the middle portion of the first cylinder 210 can be fixed to the housing 100.
[0042] Furthermore, each cylinder 200 is configured with an opening at both ends. The first support member 410 and the second support member 420 can seal the ends of each cylinder 200, ensuring that the gas-liquid mixture enters the adjacent channel through the gas connection port 204 provided on the cylinder 200. In particular, the first support member 410 needs to have a guide outlet 411 at the opening relative to the first cylinder 210 to connect the first guide channel 201 with the exhaust port 102, and the second support member 420 needs to have a drain port 421 at the corresponding position, so that the droplets settling in the baffle channel 203 and the first guide channel 201 can fall into the bottom of the shell 100.
[0043] Specifically, it could be, such as Figure 5 As shown, the second support member 420 is provided with a drain port 421 between every two adjacent cylinders 200. That is, the first guide channel 201 and each deflection channel 203 can discharge liquid to the bottom of the shell 100 through the corresponding drain port 421, so that the accumulated liquid in each channel can be discharged nearby, avoiding local accumulation of liquid from affecting the flow of the gas-liquid mixture.
[0044] In one implementation, please refer to Figures 1 to 4 and Figure 6At least one cylinder 200 has a liquid connection port 205 at its bottom, and a gas connection port 204 at the bottom of the cylinder 200 is higher than the liquid connection port 205. The liquid connection port 205 at the bottom of the cylinder 200 allows liquid connection between adjacent channels, enabling drainage through adjacent channels when the drainage load is high, thereby improving drainage efficiency and preventing the liquid level on the upper side of the second support 420 from being too high, which would affect the gas-liquid separation efficiency in the channel. It can be understood that in addition to the first cylinder 210 having a gas connection port 204 at its bottom, a third cylinder 230 may also have a gas connection port 204 at its bottom. Setting the gas connection port 204 at the bottom higher than the liquid connection port 205 allows sufficient space for the flow of the gas-liquid mixture, preventing gas from entraining liquid and causing secondary entrainment, thereby achieving independent conduction of the gas and liquid paths and minimizing the possibility of gas-liquid remixing.
[0045] Specifically, a liquid connection port 205 can be provided at the bottom of each cylinder 200 to ensure drainage efficiency. In this case, a drain port 421 can be provided only at the lowest point of the second support member 420, and drainage can be concentrated from this drain port 421. In addition, the diameter of the liquid connection port 205 and the drain port 421 can be controlled between 8 mm and 20 mm.
[0046] In one implementation, please refer to Figures 1 to 4 The second support member 420 is configured as a downward-protruding arc-shaped structure. This facilitates the guidance of the separated liquid to converge towards the central area of the second support member 420 and smoothly discharge through the drain port 421 at the lowest point of the bottom, preventing liquid stagnation or water accumulation on the support surface, thus ensuring gas-liquid separation efficiency. Simultaneously, it reduces the risk of corrosion and clogging, extending the service life of the gas-liquid separator. In other embodiments, an inclined guide surface can also be provided on the upper surface of the second support member 420.
[0047] The gas-liquid separator of this application significantly improves the ability to capture fine droplets, achieving a separation particle size of less than 50 micrometers. This significantly reduces the amount of droplets entrained in the outlet gas, thereby improving gas purity. Especially in process scenarios with strict requirements for gas moisture content, such as water electrolysis for hydrogen production, compressed air systems, and chemical reaction gas treatment, the gas-liquid separator of this application can effectively meet the demand for high-purity gas output, greatly improving gas-liquid separation efficiency and system operational reliability.
[0048] This application also proposes a water electrolysis hydrogen production system, which includes an electrolyzer and a gas-liquid separator. The specific structure of the gas-liquid separator is as described in the above embodiments. Since this water electrolysis hydrogen production system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The electrolysis product outlet of the electrolyzer is connected to the mixture inlet.
[0049] The above are merely exemplary embodiments of this application and do not limit the scope of protection of this application. All equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
