Description

Technical Field

[0001] This utility model application belongs to the field of gas-liquid separation technology and relates to gas-liquid separation devices. Background Technology

[0002] In existing technologies, gas-liquid separators widely used both domestically and internationally mainly rely on fixed baffles, swirl plates, or wire mesh packing to achieve the separation of the gas and liquid phases. The separation principle of these traditional gas-liquid separators is mainly based on gravity settling, inertial collision, or centrifugal force. For example, baffles are used to change the flow direction of the gas-liquid mixture to promote droplet settling, or wire mesh is used to capture tiny droplets. These gas-liquid separators can meet the separation requirements under normal operating conditions, but in many cases, they often reveal performance limitations, resulting in incomplete gas-liquid separation, secondary gas-liquid entrainment, and other technical problems. This leads to low separation efficiency, increased equipment maintenance costs, and even interruption of downstream processes. Utility Model Content

[0020] like Figures 1 to 8 As shown, in a first aspect, a gas-liquid separation device includes: The main body 100, the gas-liquid receiving part 200, the gas outlet part 300, the liquid outlet part 400, and the first separation part 500, the first guide part, the second guide part, the third guide part 904, the second separation part 901 located inside the main body 100, and the third separation part 902 located on the main body 100 or the gas outlet part 300. A gas-liquid receiving section 200 and a gas outlet section 300 are formed on the outside of the main body 100; The air outlet 300 is higher than the liquid outlet 400, and the liquid outlet 400 is formed at the bottom of the main body 100; The first separation section 500 connects the main body 100 and the first guide section; The second guide section is connected to the main body 100, and the first guide section is connected to the second separation section 901; The third guide section 904 connects the second separation section 901 and the liquid outlet section 400. The third guide section 904 is connected to the main body 100. The third guide section 904 has a lower curved section 9041 and an upper opening 903. The opening 903 is flush with the second separation section 901. The curved section 9041 stores liquid in advance. The third separation section 902 is connected to the gas outlet section 300. The first separation section 500 performs the first separation of the gas-liquid mixture received by the gas-liquid receiving section 200; The first guiding section guides the first separated gas-liquid mixture to form a first guided gas-liquid mixture; the second guiding section guides the liquid in the first guided gas-liquid mixture, and the guided liquid is discharged from the liquid outlet 400. The second separation section 901 separates the gas and liquid in the gas-liquid mixture after the first flow guide. The separated gas is discharged from the gas outlet section 300 through the third separation section 902, and at least part of the separated liquid is discharged from the liquid outlet section 400 after being guided by the second flow guide section; and / or, at least part of the separated liquid is also discharged from the liquid outlet section 400 after being guided by the third flow guide section 904.

[0021] In some embodiments of this utility model application, the body 100 is the main body of the gas-liquid separation device. The body 100 can be a container, tank or shell. The container can withstand pressure, and the body 100 provides the space required for the gas-liquid separation process.

[0022] In some embodiments of this utility model application, the gas-liquid receiving part 200 receives a gas-liquid mixture, which may include hydrogen and water; the gas-liquid receiving part 200 can be a gas-liquid inlet, the gas-liquid receiving part 200 is located on the outer wall of the body 100, the gas-liquid receiving part 200 connects the outside and inside of the body 100, and the gas-liquid receiving part 200 can be located on the upper part of the body 100 or near the top of the body 100.

[0023] In some embodiments of this utility model application, the third separation part 902 located on the body 100 or the air outlet 300 can be understood or meant as follows: the third separation part 902 can be directly located on the air outlet 300, in which case the third separation part 902 is connected to the air outlet 300; or, the third separation part 902 can also be directly located on the body 100, in which case the third separation part can cover the air outlet 300; or, the third separation part 902 is indirectly located on the body 100 through the air outlet 300, that is, the third separation part 902 can be connected to or cover the air outlet 300. The air outlet 300 is used to discharge the gas separated by the third separation part 902. The air outlet 300 is an air outlet. The air outlet 300 is located on the outer wall of the body 100. The air outlet 300 connects the interior and exterior of the body 100. The air outlet 300 can be located on the upper part of the body 100 or near the top of the body 100.

[0024] In some embodiments of this utility model application, the first separation part 500 is located inside the body 100 and is positioned opposite the gas-liquid receiving part 200. The first separation part 500 is connected to the body 100. The first separation part 500 can be a baffle installed on the inner wall of the body 100. The baffle can also be annular. The first separation part 500 can prevent liquid (e.g., droplets or water vapor) in the gas-liquid mixture from entering the upper part of the body 100. At the same time, the first separation part 500 can withstand the impact of gas and liquid (i.e., gas and liquid) in the gas-liquid mixture. By colliding with the gas-liquid mixture, most of the impact kinetic energy of the gas and liquid is consumed, the flow rate of the gas and liquid is reduced, and most of the liquid is separated for the first time.

[0025] In some embodiments of this utility model application, the first guide section is located inside the body 100 and is connected to the first separation section 500. It is used to guide the gas-liquid mixture separated by the first separation section for the first time. The first guide section can take the form of an inclined guide structure, a spiral guide structure, or a conical guide structure, etc. One end is connected to the first separation section, and the other end extends to the lower part of the internal space of the body 100, thereby guiding the gas-liquid mixture after the first separation along a predetermined path to achieve preliminary flow direction adjustment and speed reduction. In the gas-liquid mixture after the first guide section (hereinafter referred to as the "gas-liquid mixture after the first guide"), the gas and liquid are initially separated. Most of the liquid (e.g., larger droplets) settles downwards under gravity, while the gas in the gas-liquid mixture after the first guide (which may also contain trace amounts of liquid) continues to flow upwards.

[0026] Furthermore, the second guide section is located inside the main body 100, positioned below the first guide section and connected to the main body 100. It is used to guide the liquid in the gas-liquid mixture after the first guide. The second guide section can take the form of a funnel-shaped collection structure, a multi-stage stepped guide structure, or a guide slope structure. The upper part of the second guide section faces the gas-liquid mixture after the first guide, guiding and collecting the separated fluid (e.g., droplets or liquid films in the gas-liquid mixture after the first guide), while the lower part connects to the liquid outlet 400. Through the guiding effect of the second guide section, the liquid in the gas-liquid mixture after the first guide is effectively guided to the liquid outlet 400 and discharged from it, thereby achieving liquid collection and discharge.

[0027] In some embodiments of this utility model application, the second separation section 901 is located inside the body 100, the first guide section is connected to the second separation section 901, the second separation section 901 can be disposed above the first guide section, and is used to perform secondary separation of gas in the gas-liquid mixture after the first guide. The second separation section 901 can be in the form of a porous filter medium or a hydrogen selective separation membrane, preferably a palladium or palladium alloy hydrogen separation membrane, or the second separation section 901 can also be installed in the upper middle part of the body 100. The second separation section 901 can be connected to the first guide section, and the third separation section 902 can be connected to or cover the gas outlet section 300.

[0028] In some embodiments of this utility model application, the liquid (e.g., droplets or mist-like water vapor) in the gas-liquid mixture after the first diversion is intercepted and separated by the second separation section 901. After interception and separation, the liquid can be diverted by the second diversion section and discharged from the liquid outlet section 400. That is, at least part of the separated liquid is diverted by the second diversion section and discharged from the liquid outlet section 400. Most of the gas in the gas-liquid mixture after the first diversion flows upward through the second separation section 901. The gas separated by the second separation section 901 passes through the third separation section 902 again and is directly discharged from the gas outlet section 300, realizing the purified output of the gas. At the same time, there may still be trace amounts of liquid in the gas after separation by the second separation section. Correspondingly, the trace amounts of liquid separated by the second separation section can be diverted by the third diversion section and discharged from the liquid outlet section 400. That is, at least part of the separated liquid is diverted by the third diversion section and discharged from the liquid outlet section 400.

[0029] In some embodiments of this utility model, at least partially separated liquid flows downward under gravity and is further guided by the second guide section before being discharged from the liquid outlet 400, ensuring as much as possible the complete recovery of liquid in the gas-liquid mixture; at the same time, the third guide section 904 is disposed inside the body 100, and part of the sidewall of the third guide section 904 can be connected to the inner wall of the body 100. One side of the third guide section 904 is connected to the second separation section 901, and the other side is connected to the liquid outlet 400, thereby forming a closed liquid guiding channel. At least partially separated liquid can also flow smoothly to the liquid outlet 400 through the third guide section 904 and under gravity.

[0030] In some embodiments of this utility model, the third guide section 904 can be in the form of a tubular structure, extending along the side wall of the body 100. The third guide section 904 is at least partially connected to the side wall of the body 100, and its diameter is suitable for accommodating at least partially separated liquid captured by the second separation section. It can be made of corrosion-resistant materials (such as stainless steel or engineering plastics). The third guide section 904 has a lower curved section 9041 and an upper opening 903. The opening 903 is connected to the gas outlet 300. The opening 903 (upper surface) is flush with the second separation section 901 (upper surface). The curved section 9041 is preferably a U-shaped or S-shaped bent structure. Multiple curved sections 9041 can be provided. They are located in the lower section of the third guide section 904. A receiving cavity is provided at the bottom of the curved section 9041. The receiving cavity stores liquid in advance. The pre-stored liquid can be injected initially and then settled at the bottom of the receiving cavity due to gravity, thereby forming a liquid seal effect. This not only prevents the gas separated by the second separation section 901 from flowing out of the liquid outlet 400, but also prevents the gas near the liquid outlet 400 from flowing back into the third separation section 902.

[0031] In some embodiments of this utility model application, the liquid outlet 400 is used to discharge the separated liquid. The liquid outlet 400 is a liquid outlet located at the bottom of the body 100. The liquid outlet 400 connects the inside and outside of the body 100. The liquid outlet 400 can continuously or intermittently discharge the liquid after being guided by the second guide section and the liquid after being guided by the third guide section.

[0032] In the gas-liquid separation device of this utility model application, firstly, by integrating a multi-stage synergistic structure of a first separation section, a first guide section, a second guide section, a third guide section, a second separation section, and a third separation section inside the main body, the impact kinetic energy of the gas-liquid mixture is consumed and the flow rate is reduced, realizing the primary and secondary separation of the gas-liquid mixture, reducing or avoiding the problem of secondary gas-liquid entrainment, and improving the purity of the separated gas and the liquid recovery rate. In addition, the first separation section, as a baffle-type impact buffer component, can withstand the direct collision of high-pressure, high-flow-rate gas-liquid mixture, initially separating large liquid particles, while preventing droplets or water vapor from escaping upward into the upper space of the main body. The second guide section guides the liquid in the gas-liquid mixture after the first guide and the liquid after the second separation to the liquid outlet, realizing the continuous or intermittent discharge of liquid, improving the purified output of gas and the complete recovery of liquid.

[0033] Preferably, the first guide section includes a central guide pipe 600 and a plurality of guide plates 700, the first separation section 500 connects the central guide pipe 600 and the inner wall of the body 100, and the plurality of guide plates 700 are formed in a circumferential upward manner around the outer periphery of the central guide pipe 600.

[0034] In some embodiments of this utility model application, the central guide pipe 600 can be a pipe, which can be arranged along the height direction of the gas-liquid separator. The central guide pipe 600 can be directly or indirectly connected to the first separation section to guide the gas-liquid mixture after the first separation.

[0035] In some embodiments of this utility model application, the guide plate 700 can be a blade with a certain angle. The guide plate 700 is installed around the central guide pipe 600. Multiple guide plates 700 are formed around the outer periphery of the central guide pipe 600 in a circumferential upward manner. Preferably, multiple guide plates 700 are formed around the outer periphery of the central guide pipe 600 in a circumferential spiral upward manner. The guide plate 700 may or may not have a certain distance from the inner wall of the body 100. The guide plate 700 may be connected to the inner wall of the body 100.

[0036] In some embodiments of this utility model application, the central guide tube 600 and multiple guide plates 700 work together to guide the gas-liquid mixture after the first separation by the first separation section 500, and cause the gas-liquid mixture after the first separation to rotate. The centrifugal force generated is used to throw the droplets onto the inner wall of the body 100 and the multiple guide plates 700 to form a first guided gas-liquid mixture. The second guide section guides the liquid in the first guided gas-liquid mixture, and the guided liquid is discharged from the liquid outlet 400 at the bottom of the body.

[0037] Preferably, the second separation section 901 includes a first separation membrane, which is connected to the central guide tube 600 and the inner wall of the body 100, and is located above the central guide tube 600; the third separation section 902 includes a second separation membrane, which is located above the opening 903, and is connected to the air outlet section 300.

[0038] In some embodiments of this utility model application, the first separation part 500 and the second separation part 901 are independent components. The second separation part 901 is located above the first separation part 500. The first separation part 500 is connected to the second separation part 901. The second separation part 901 or the first separation membrane is directly connected to the central guide tube 600 and the inner wall of the body 100.

[0039] In some other embodiments of this utility model application, alternatively, the second separation part 901 covers the opening of the central guide tube 600. For example, the second separation part 901 is circular and matches the opening. The first separation part 500 and the second separation part 901 can be independent components or integrally formed parts, that is, the first separation part 500 and the second separation part 901 are connected as one piece or integrally formed. Furthermore, the whole formed by the first separation part 500 and the second separation part 901 can be inclined. In this case, correspondingly, the third guide part 904 connects the first separation part 500 and the liquid outlet part 400. The third guide part 904 is connected to the body 100. The third guide part 904 has a lower curved part 9041 and an upper opening 903. The opening 903 is flush with the first separation part 500. The curved part 9041 stores liquid in advance. The third separation part 902 is connected to the gas outlet part 300. The second separation part 901 or the first separation membrane is also still connected to the central guide tube 600 and the inner wall of the body 100.

[0040] In some embodiments of this utility model application, the first separation membrane can be tilted (e.g., 30°, 45°, etc.), the first separation membrane is a hydrogen separation membrane and / or the second separation membrane is a hydrogen separation membrane, the material of the hydrogen separation membrane includes palladium or palladium alloy, for example, Pd-Ag alloy, etc., or it can be electrically heated if necessary, of course it can also be other existing materials or other existing types of hydrogen separation membranes, this utility model application does not limit it in this regard.

[0041] In some embodiments of this utility model application, selective separation of hydrogen in the gas-liquid mixture after the first flow is achieved through a dual-membrane structure of a first separation membrane and a second separation membrane. The first separation membrane is connected to the central guide tube 600, with its lower part exposed to the gas-liquid mixture after the first flow, and its upper part can cooperate with the second separation membrane. The second separation membrane is located above the opening 903 and is directly connected to the gas outlet 300, thus forming a dual-separation membrane structure configuration.

[0042] In this utility model application, the central guide tube 600 guides the gas-liquid mixture after the first guide flow to the second separation section. After the gas-liquid mixture (containing hydrogen and other gases or liquids) enters the second separation section 901, hydrogen molecules (H2) first enter the first separation membrane, and then are purified and output from the outlet side of the second separation membrane to the outlet section 300. The separation membrane allows hydrogen to permeate through, while other gases (such as nitrogen, oxygen, or residual liquid vapor) are blocked outside the separation membrane because they cannot diffuse. The first and second separation membranes are mainly responsible for capturing and separating hydrogen, which can realize multi-stage purification of hydrogen. During the separation process, residual liquid or non-hydrogen gases settle downwards under the action of gravity and the interception of the separation membrane. At least part of the separated liquid is collected by the second guide section and discharged from the liquid outlet section 400. Thus, the dual-membrane hydrogen selective separation structure improves the hydrogen purification efficiency and selectivity of the gas-liquid separation device. Compared with single membrane or traditional mechanical separation methods, it achieves high-purity hydrogen output and high hydrogen recovery rate.

[0043] Preferably, the second guide section is located below the first guide section. The second guide section includes a first inclined guide section 801, a second inclined guide section 802 and a bottom 803. A plurality of guide holes 804 are formed on the bottom 803. The guide holes 804 are connected to the central guide pipe 600 and the liquid outlet section 400.

[0044] In some embodiments of this utility model application, the second guide section is located below the first guide section and is formed in the lower middle space inside the body 100. It can be used to guide the liquid in the gas-liquid mixture after the first guide section. The second guide section includes a first inclined guide section 801, a second inclined guide section 802, and a bottom 803. The first inclined guide section 801 and the second inclined guide section 802 are arranged symmetrically or alternately (the inclination angle can be 30°-60°). The first inclined guide section 801 and the second inclined guide section 802 are inclined below the first guide section. The bottom 803 can be a basically horizontal mounting plate, connecting plate, mounting platform, or connecting platform, which is fixedly connected to the inner wall of the body 100. It can form a funnel-shaped or stepped structure with the lower part of the body 100 and the liquid outlet 400. Multiple guide holes 804 can be evenly or not completely evenly distributed circumferentially on the bottom 803. These guide holes are directly connected to the central guide pipe 600 and the liquid outlet 400 to realize the downward guide path of the liquid under the action of gravity. Specifically: After the first guide, the gas-liquid mixture flows downward through the first guide section. Under the action of gravity, the liquid (including droplets and / or liquid films, such as large droplets and small liquid films) contacts the first inclined guide section 801 and / or the second inclined guide section 802 and / or the bottom 803. The inclined guide structure can guide the liquid to slide along the inclined surface through surface tension and inertia, ensuring that the liquid converges to the bottom 803. At the same time, the gas in the gas-liquid mixture after the first guide flows upward to the second separation section. The liquid that reaches the bottom 803 is driven by gravity and enters the lower part of the body 100 through multiple guide holes, and finally is discharged from the liquid outlet 400.

[0045] Preferably, the liquid outlet 400 is equipped with a pressure regulating valve and a liquid level sensor.

[0046] In some preferred embodiments of this utility model application, the liquid outlet 400 is disposed at the bottom of the main body 100 and serves as the liquid outlet of the gas-liquid separation device. The liquid outlet of the liquid outlet 400 is a circular or rectangular pipe that communicates with the interior of the main body 100 and directly discharges the liquid after being guided by the second guide section through the pipe.

[0047] In some preferred embodiments of this utility model application, a pressure regulating valve (e.g., a solenoid valve or a back pressure valve) is installed on the outer pipe of the outlet to control liquid discharge. A level sensor (e.g., an ultrasonic level gauge or a float sensor) is installed inside the outlet section 400 or below the bottom 803 to monitor the liquid accumulation height at the bottom 803 of the second guide section in real time. In actual operation, the level sensor continuously detects the liquid level height at the bottom 803 and can transmit the liquid level height data to the control system. When the liquid level reaches a preset threshold, the control system triggers the pressure regulating valve to open, and the liquid is discharged through the outlet; when the liquid level is below a safety threshold, the control system closes the outlet to prevent excessive discharge, thereby achieving continuous or intermittent liquid discharge.

[0048] The working method of the gas-liquid separation device of this utility model application is as follows: Step S100: The first separation unit 500 performs a first separation on the gas-liquid mixture received by the gas-liquid receiving unit 200; the first guiding unit guides the first separated gas-liquid mixture for the first time to form a first guided gas-liquid mixture.

[0049] In step S100, the first separation unit 500 performs the first separation of the gas-liquid mixture received by the gas-liquid receiving unit 200, which includes: the first separation unit 500 is subjected to the impact of the gas-liquid mixture (i.e., gas and liquid), and consumes most of the kinetic energy of the gas and liquid by colliding with the gas-liquid mixture, thereby reducing the flow rate of the gas and liquid and separating most of the liquid for the first time.

[0050] In step S100, the first guiding section guides the first separated gas-liquid mixture for the first time to form the first guided gas-liquid mixture. This includes the first guiding section guiding the gas-liquid mixture separated by the first separation section for the first time. The central guiding pipe 600 and multiple guiding plates 700 work together to guide the gas-liquid mixture separated by the first separation section 500 for the first time, and cause the gas-liquid mixture separated by the first separation to rotate. The centrifugal force generated is used to throw the droplets onto the inner wall of the body 100 and the multiple guiding plates 700 to form the first guided gas-liquid mixture.

[0051] Step S200: The second guide section guides the liquid in the gas-liquid mixture after the first guide, and the guided liquid is discharged from the liquid outlet 400; the second separation section separates the gas and liquid in the gas-liquid mixture after the first guide, and the separated gas is discharged from the gas outlet 300 through the third separation section 902, and at least part of the separated liquid is discharged from the liquid outlet after being guided by the second guide section; and / or, at least part of the separated liquid is also discharged from the liquid outlet after being guided by the third guide section.

[0052] In step S200, the second separation section 901 can separate the gas in the gas-liquid mixture after the first flow, and the separated gas can be discharged from the gas outlet 300 through the third separation section 902. This includes: when most of the gas in the gas-liquid mixture after the first flow enters the second separation section, hydrogen molecules (H2) first enter the first separation membrane, and then are purified and output from the second separation membrane on the gas outlet side to the gas outlet 300.

[0053] In step S200, the second guiding section guides the liquid in the gas-liquid mixture after the first guiding, and the guided liquid is discharged from the liquid outlet 400. This includes: the first inclined guiding section 801 and the second inclined guiding section 802 are inclined below the first guiding section, capturing the liquid that settles from the gas-liquid mixture after the first guiding. The liquid flows through the guiding hole to the liquid outlet 400, realizing a downward guiding path for the liquid under the action of gravity, and finally being discharged continuously or intermittently from the liquid outlet 400. At the same time, the second separation section can separate the liquid in the gas-liquid mixture after the first guiding. At least part of the separated liquid is guided by the second guiding section and discharged from the liquid outlet; and / or, at least part of the separated liquid is also guided by the third guiding section 904 and discharged from the liquid outlet. These can be referred to in the foregoing content, and will not be repeated in this utility model application.
