Description

Technical Field

[0002] Evaporation is an important unit operation in chemical production and is widely used in chemical, pharmaceutical, food and other industries. During the evaporation process, after the material undergoes heat exchange in the heating chamber, the gas-liquid mixture enters the separation chamber for gas-liquid separation.

[0003] The working principle of the separation chamber is to utilize the gas-liquid two-phase flow to rotate along the tangential feed of the cylinder of the separation chamber, wherein the liquid phase fluid is thrown toward the cylinder wall because the centrifugal force is much greater than that of the gas phase fluid. Under the action of gravity, it falls along the inner wall of the cylinder and flows out along the liquid outlet of the separation tank. The gas phase fluid overflows along the gas outlet at the top of the separation tank, thereby separating the gas and liquid phases.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] As mentioned in the background technology, the existing gas-liquid separation steps are mostly completed inside the container of the production equipment, and a gas-liquid separation chamber is separately set in the container. A plurality of filter screens, baffles and cyclone separation structures are sequentially set in the gas-liquid separation chamber. However, it not only takes up a large space, but also has low separation efficiency. Different equipment needs to set up gas-liquid separation chambers separately to meet the needs, resulting in a one-to-one matching relationship between the gas-liquid separator and the container, which reduces the versatility of the gas-liquid separator. Therefore, in response to the above technical problems, the gas-liquid separator adopted by the present application is provided with a first separation component 400 and a second separation component 500 on the storage body 300. The first separation component 400 and the second separation component 500 are arranged in parallel, realizing two separations of the gas-liquid mixture, namely, a primary separation by impact and a secondary separation by centrifugation, which significantly improves the separation efficiency compared with the single-stage separator. The first separation component 410 can quickly separate large particle droplets through impact, while the second separation component 510 further removes fine droplets by centrifugal force to ensure the purity of the gas. The second separation assembly 500 is arranged on the side of the first separation assembly 400 and is connected through the storage chamber 310, which not only makes full use of the external space of the container and improves the overall volume utilization of the device, but also simplifies the internal structure of the container, avoids the interference of complex internal components on the flow of fluid, and reduces the maintenance cost and manufacturing difficulty of the separator. The end of the second separation assembly 500 away from the storage chamber is connected to the gas outlet channel 200, so that the gas after secondary separation can be discharged directly, reducing the residence time of the gas inside the container, avoiding remixing, and improving the stability and reliability of the separator.

[0046] Please refer to Figures 1 to 18 The present application provides a gas-liquid separator, including a steam inlet channel 100 and a gas outlet channel 200, and the gas-liquid separator also includes: a storage body 300, the storage body 300 has a storage chamber 310; a first separation component 400, which is connected to the steam inlet channel 100; a second separation component 500, which is connected to the gas outlet channel 200, the second separation component 500 and the first separation component 400 are arranged in parallel on the storage body 300, and the first separation component 400 and the second separation component 500 are connected through the storage chamber 310; the first separation component 400 includes a first separation part 410, and the first separation part 410 is arranged opposite to the inlet of the steam inlet channel 100, so that the gas-liquid mixture in the steam inlet channel 100 is subjected to a primary gas-liquid separation by impacting the first separation part 410; the second separation component 500 includes a second separation part 510, and the second separation part 510 is rotatably arranged around a predetermined axis, so that when the gas-liquid mixture after the primary gas-liquid separation flows through the second separation part 510, a secondary gas-liquid separation is performed by using centrifugal force.

[0047] The gas-liquid separator according to the present application includes a steam inlet channel 100 and a gas outlet channel 200, and the gas-liquid separator also includes a storage body 300, a first separation component 400 and a second separation component 500. The storage body 300 has a storage cavity 310; the first separation component 400 is communicated with the steam inlet channel 100; the second separation component 500 is communicated with the gas outlet channel 200, and the second separation component 500 is arranged in parallel with the first separation component 400 on the storage body 300, and the first separation component 400 and the second separation component 500 are connected through the storage cavity 310 is connected; the first separation component 400 includes a first separation component 410, which is arranged relative to the inlet of the steam inlet channel 100, so that the gas-liquid mixture in the steam inlet channel 100 can be separated into gas and liquid by impacting the first separation component 410; the second separation component 500 includes a second separation component 510, which is rotatably arranged around a predetermined axis, so that when the gas-liquid mixture after the primary gas-liquid separation flows through the second separation component 510, the centrifugal force can be used to perform a secondary gas-liquid separation. The steam inlet channel 100 and the gas outlet channel 200 serve as channels for gas to enter and gas to leave, respectively. A storage cavity 310 is formed inside the storage body 300 for temporarily storing the separated liquid. The first separation component 410 is used to perform preliminary gas-liquid separation by impact separation. The second separation component 510 can generate a strong centrifugal force during rotation to completely separate the fine droplets carried in the gas-liquid mixture after the first separation, which significantly improves the purity of the gas and the efficiency of gas-liquid separation. In addition, the gas-liquid separator is arranged outside the container, and the gas-liquid separation process is completed outside the container. It can be used as a universal separator for various types of gas-liquid mixtures.

[0048] Specifically, Figure 1 , Figures 16 to 18 As shown, the gas-liquid separator also includes: a drainage component 600, which is arranged in the storage chamber 310 and is located below the first separation component 400 and the second separation component 500. The drainage component 600 divides the storage chamber 310 into a drainage area 311 and a liquid storage area 312; a plurality of first through holes 610 are arranged on the drainage component 600, and the liquid after the gas-liquid separation falls into the liquid storage area 312 through the plurality of first through holes 610 for storage. After hitting the first separation component 410, the liquid falls into the liquid storage area 312 through each of the first through holes 610, and part of the gas flows along the drainage component 600 in the drainage area 311 to the second separation component 500 due to its light weight, and is sucked into the second separation component 510 under the centrifugal force of the second separation component 510 for secondary separation.

[0049] Specifically, the drainage component 600 includes: a first drainage body 620 and a second drainage body 630 connected to each other, the first drainage body 620 is located below the first separation component 400, and the second drainage body 630 is located below the second separation component 500; each first through hole 610 is provided on the second drainage body 630. Among them, the first through hole 610 is not provided on the first drainage body 620, in order to prevent the impact on the liquid surface of the liquid storage area 312, so that the gas carries large droplets through the second separation component 510 to affect the separation efficiency, and at the same time avoid the impact on the liquid surface to generate fluctuations that affect the liquid level in the liquid storage area 312 observed by the liquid level display. Therefore, after the first drainage body 620 is buffered, when the separated gas, liquid or gas-liquid mixture flows into the second drainage body 630, the liquid flows into the liquid storage area 312 through the first through hole 610, and the gas and gas-liquid mixture enter the second separation component 500 for secondary separation due to their lighter weight.

[0050] Preferably, the drainage component 600 is a plate structure, with the direction from the first separation component 400 to the second separation component 500 as the length direction and the direction perpendicular to the length direction as the width direction; along the width direction of the plate structure, the plate structure extends along a predetermined arc track. The design of this arc track can better adapt to the effect of centrifugal force, so that the liquid flows more smoothly into the liquid storage area 312, reducing the energy consumption of the equipment. In addition, in order to avoid part of the gas flow channel liquid storage area 312, the arc-shaped plate surface is used to guide the gas so that the gas can enter the second separation component 500.

[0051] like Figures 2 to 6 As shown, the first separation component 400 further includes: a first support component 420, which is opposite to the steam inlet channel 100, and a first separation component 410 is arranged at the top of the first support component 420; a first filter component 430, which is arranged around the first separation component 410. After the gas-liquid mixture hits the first separation component 410, part of the liquid adheres to the first filter component 430 and flows into the storage chamber 310, and part of the gas flows into the second separation component 500 after passing through the first filter component 430. In this arrangement, the first support component 420 is used to support the first separation component 410, and the first filter component 430 is arranged around the first separation component 410, so that after the gas-liquid mixture hits the first separation component 410, the mixture splashed to the surroundings can be evenly attached to the first filter component 430, thereby improving the effect of gas-liquid separation.

[0052] Specifically, the first separation component 410 is firmly arranged at the outlet of the steam inlet channel 100 through the first support component 420, ensuring that the high-speed gas-liquid mixture can accurately hit the first separation component 410. This direct impact can effectively decompose large droplets, thereby improving the efficiency of primary separation of gas and liquid. The first filter component 430 is not only arranged around the first separation component 410, but also provides an additional filter barrier for the separated gas, which can further capture the fine droplets carried in the gas, ensuring that the gas entering the second separation component 500 is purer, and improving the final separation accuracy. After the gas-liquid mixture hits and is initially separated, part of the liquid can directly adhere to the first filter component 430 and flow into the storage chamber 310 under the action of gravity. This design optimizes the liquid recovery path, prevents the liquid from being carried again, and thus improves the efficiency and accuracy of liquid recovery. The setting of the first support component 420 not only provides a stable support for the first separation component 410, but also simplifies the overall structure of the first separation component 400, reduces unnecessary internal components, thereby improving the volume utilization of the equipment, and reducing manufacturing costs and maintenance difficulties. Through the above design of the first separation component 400, the entire gas-liquid separation process is more stable, the system fluctuation caused by the gas-liquid mixture directly impacting the subsequent components is reduced, and the stability and reliability of the separator operation are guaranteed. It can adapt to different operating conditions, such as flow changes, gas-liquid ratio fluctuations, etc., and improve the adaptability and separation effect of the separator under variable working conditions.

[0053] like Figure 5 As shown, the first filter component 430 includes: a first filter body 431 and a second filter body 432 connected to each other, the first filter body 431 is arranged around the first separation component 410, the second filter body 432 is located below the first separation component 410, the second filter body 432 is provided with a first avoidance hole 4320, and the end of the first support component 420 away from the first separation component 410 is arranged in the first avoidance hole 4320. This structure optimizes the layout of the first filter component 430, improves the filtering effect, reduces energy consumption, and is suitable for industrial production environments that require efficient filtering and energy saving. This optimized layout design enables the first filter component 430 to filter more effectively, and reduces unnecessary resistance and energy consumption when airflow passes through.

[0054] Furthermore, the first filter body 431 is arranged around the first separation component 410, and can directly capture the droplets generated after the initial impact. The combined structure of the first filter body 431 and the second filter body 432 provides an optimized path for the airflow, avoiding the additional resistance of the airflow due to too many obstacles, thereby reducing energy loss and improving the working efficiency of the separator. The existence of the first avoidance hole 4320 not only ensures the stable connection of the first support component 420, but also provides a solid structural support for the entire first separation assembly 400. This design enhances the mechanical stability of the separator and improves the operational reliability of the system. By designing the first filter component 430 as two interconnected but independent parts, the assembly steps in the manufacturing process are simplified, the manufacturing difficulty is reduced, the production speed is accelerated, and it is conducive to large-scale production. The design of the first filter component 430 can adapt to different types of gas-liquid separation requirements, whether it is an oil separator, a flasher or other applications, it can effectively improve the separation effect and enhance the compatibility of the separator in various application scenarios.

[0055] During the specific implementation process, the first separation component 400 also includes: a first cylinder 440, which is arranged on the storage body 300, and the steam inlet channel 100 is arranged at the top of the first cylinder 440; a second support component 450, the second support component 450 is arranged in the first cylinder 440, the second support component 450 includes a first support body 451 and a second support body 452, the first support body 451 is connected to the inner wall surface of the first cylinder 440, the end of the first support component 420 away from the first separation component 410 is connected to the first support body 451, the second support body 452 is arranged on the first support body 451, and the extension direction of the second support body 452 is consistent with the axial direction of the first cylinder 440; the second support body 452 is an annular structure, the first filter component 430 is connected to the inner wall surface of the second support body 452, and a gas flow channel 460 is arranged between the outer wall surface of the second support body 452 and the inner wall surface of the first cylinder 440.

[0056] The combination of the first cylinder 440 and the storage body 300, and the arrangement of the second support component 450 in the first cylinder 440, provide a more stable structural support for the entire separation component. The synergistic effect of the first support body 451 and the second support body 452 ensures the structural stability of the first separation component 410 and the first filter component 430 under the impact of high-speed airflow and the continuity of the separation process. The arrangement of the gas flow channel 460 optimizes the guiding path of the airflow, reduces the resistance of the gas when it flows through the first separation component 400, and enables the gas after preliminary separation to flow more smoothly to the second separation component 500 without generating excessive turbulence or backflow in the intermediate stage, thereby improving the separation efficiency and purity of the gas. The standardized design of the first cylinder 440 and the second support component 450 simplifies the manufacturing and assembly process, reduces production costs, speeds up production speed, and is conducive to large-scale production.

[0057] Furthermore, a plurality of second through holes 453 are respectively provided on the first support body 451 and the second support body 452, and each second through hole 453 is arranged at intervals, and after the gas-liquid mixture hits the first separation component 410, part of the gas flows out through each second through hole 453. The design of each second through hole 453 ensures the uniformity of gas flow, and after part of the gas passes through the first filter body 431, it can flow out through each second through hole 453.

[0058] Specifically, the second support body 452 divides the first support body 451 into a first area opposite to the first separation component 410, and a second area opposite to the gas flow channel 460, wherein each second through hole 453 is arranged in the first area, and a fourth through hole 454 is arranged in the second area, and the fourth through hole 454 extends along the circumferential direction of the first support body 451, wherein the cross-sectional area of ​​the through section of the fourth through hole 454 is larger than the cross-sectional area of ​​the through section of the second through hole 453. Such an arrangement is conducive to accelerating the speed of gas passing through the gas flow channel 460.

[0059] In the embodiments provided in this application, Figure 7As shown, the second separation assembly 500 further includes: a second barrel 520, which is arranged on the storage body 300, the air outlet channel 200 is arranged at the top of the second barrel 520, and the second separation component 510 is arranged in the second barrel 520; a second filter component 530, which is covered above the second separation component 510, and the gas separated by the second separation component 510 flows out after passing through the second filter component 530, and the liquid separated by the second separation component 510 adheres to the second filter component 530 and flows into the storage chamber 310. Among them, a fourth support component 550 is arranged above the second filter component 530, and a fifth through hole 551 is arranged on the fourth support component 550. The fifth through hole 551 is arranged opposite to the air outlet channel 200, and part of the gas passing through the second filter component 530 is discharged after passing through the fifth through hole 551. In this arrangement, the fourth support component 550 can be used to block the liquid on the second filter component 530, and at the same time, the third support component 540 is used to ensure the stable installation of the second filter component 530.

[0060] The second cylinder 520 provides an independent operating space for the second separation component 510, ensuring that the centrifugal force can fully act on the gas-liquid mixture, thereby achieving a more efficient secondary separation. At the same time, the structure of the second cylinder enhances the mechanical stability of the entire assembly and reduces the vibration and noise that may be generated by high-speed rotation. The second filter component 530 is provided to provide an additional filter barrier for the gas after centrifugal separation by the second separation component 510, which can capture and remove the fine droplets remaining in the gas flow, significantly improve the purity of the outflowing gas, and reduce the potential impact on subsequent processes or equipment. The separated liquid adheres to the second filter component 530 under the action of gravity, and then flows smoothly into the storage chamber 310. This design optimizes the liquid recovery process, avoids the re-carrying of the liquid, enhances the stability of the separation effect, and also reduces the direct impact of the liquid on the internal structure of the second separation component; the second filter component 530 and the second separation component 510 are used in combination to reduce the energy loss caused by collision and turbulence in the separation process of the gas, improve the operating efficiency of the system, and reduce the overall energy consumption. The provision of the second cylinder 520 not only provides protection for the second separation component 510 and the second filter component 530, but also facilitates disassembly and cleaning during maintenance, thereby reducing the maintenance cost of the equipment and extending its service life.

[0061] like Fig.13 and Fig.14As shown, the second separation assembly 500 further includes: a third support member 540, which is arranged in the second cylinder 520, the second separation member 510 is arranged on the third support member 540, and the second filter member 530 is arranged on the third support member 540 and is in contact with the third support member 540; a plurality of third through holes 541 are arranged on the third support member 540, at least part of the plurality of third through holes 541 are opposite to the second filter member 530, and the liquid on the second filter member 530 flows into the storage chamber 310 through the third through holes 541. Among them, a second avoidance hole 542 is arranged in the middle of the third support member 540, and at least part of the second separation member 510 is penetrated in the second avoidance hole 542, so that the steam suction end of the second separation member 510 is located in the drainage area 311 of the storage chamber 310, so as to prevent the steam in the drainage area 311 from directly passing through the second filter member 530 and affecting the separation accuracy.

[0062] The third support component 540 supports the second separation component 510 to ensure stability and reliability during high-speed rotation, while the second filter component 530 further filters the tiny droplets in the airflow, improves the efficiency of secondary separation, and ensures the high purity of the gas. The design of multiple third through holes 541 allows the liquid collected on the second filter component 530 to flow directly and quickly into the storage chamber 310, avoiding the retention and secondary carrying of the liquid inside the container, and improving the efficiency and accuracy of liquid recovery. The fitting design between the third support component 540 and the second filter component 530, as well as the precise arrangement of the third through holes 541, reduces the resistance during the gas flow process, reduces the energy consumption during the separation process, and improves the overall operating efficiency of the system. The arrangement of the third support component 540 in the second cylinder 520 provides a more stable and reliable support for the entire second separation assembly, ensures the structural stability under high-speed rotation and complex working conditions, and extends the service life of the equipment. By rationally arranging the third support component 540 and the second filter component 530 in the second cylinder 520, the space occupied by the internal components is reduced, the spatial layout of the storage chamber 310 is optimized, and the overall volume utilization of the separator is improved.

[0063] like Figure 6As shown, the first separation component 410 includes: a protruding body 411, which is arranged opposite to the steam inlet channel 100, and an impact end face 412 is arranged on the protruding body 411, and the impact end face 412 is an arc-shaped surface; a flow-guiding body 413, which is connected to the protruding body 411, and the flow-guiding body 413 is arranged around the protruding body 411, and a flow-guiding end face 414 is arranged on the flow-guiding body 413, and at least part of the flow-guiding end face 414 is a curved surface. The arc-shaped impact end face 412 on the protruding body 411 can make the gas-liquid mixture entering at a high speed produce a diffusion effect when it collides, and the arc-shaped surface helps the droplets in the gas-liquid mixture to change the flow direction due to the collision, so as to be more effectively separated from the airflow, thereby improving the efficiency of the primary separation. The guide end surface 414 on the guide body 413 adopts a curved surface design, which can guide the separated droplets to flow smoothly along the curved surface, reduce the retention time of the droplets on the surface, prevent the droplets from being re-involved by the airflow, ensure that the droplets can quickly fall into the storage chamber 310, and improve the efficiency of liquid recovery. The arc design of the protruding body 411 and the curved surface of the guide body 413 can reduce the resistance of the airflow during the impact and diversion process, reduce energy loss, and enable the separated gas to enter the subsequent separation components more smoothly, thereby improving the overall operating efficiency of the system.

[0064] Preferably, the protruding body 411 and the flow guiding body 413 are integrally formed, which improves the structural strength of the first separation component 410, wherein the first separation component 410 is an umbrella-shaped structure, which can reduce the resistance of the airflow during the collision and flow guiding process. This not only significantly improves the efficiency and accuracy of the primary separation, but also optimizes the airflow distribution, reduces energy loss and mechanical wear, and enhances the stability and versatility of the system.

[0065] The second separation component 510 includes: a centrifugal impeller 511, which is rotatably arranged around its own axis, and a guide channel 512 is arranged in the centrifugal impeller 511, through which the gas-liquid mixture that has undergone a gas-liquid separation is guided. The high-speed rotation of the centrifugal impeller 511 can generate a strong centrifugal force, which can further separate the gas-liquid mixture preliminarily separated from the first separation component, and throw smaller droplets out of the airflow. These droplets will flow down along the surface of the second filter component 530, and finally return to the storage chamber 310 through a specific path, optimizing the liquid recovery path and avoiding the re-carrying of droplets. The setting of the guide channel 512 effectively guides the gas-liquid mixture entering the centrifugal impeller, which can guide the gas to enter the impeller at a more uniform speed and direction, avoiding the direct impact or uneven distribution of the airflow, and improving the stability and consistency of centrifugal separation.

[0066] During the specific implementation process, a liquid level display 700 is provided on the storage body 300, and a liquid level display 700 is provided in the liquid storage area 312, so as to facilitate observation of the liquid level in the liquid storage area 312. A liquid outlet 800 connected to the liquid storage area 312 is provided at the bottom of the storage body 300 for discharging liquid. A plurality of brackets 900 are provided at the bottom of the storage body 300 for supporting the storage body 300.

[0067] The first separation component 400 and the second separation component 500 of the present application are arranged outside the container, and the gas-liquid separation process is all completed outside the container, which greatly improves the volume utilization rate and saves the space occupied by the internal parts. The first separation component 410 is arranged at the inlet of the container, and the multi-directional centrifugal separation impeller is arranged at the outlet. The first separation component 410 decomposes the large droplets and then the gas and liquid flow to the outlet and then filter the small droplets through the multi-directional centrifugal separation impeller. The drainage component 600 is arranged at the inlet of the second separation component 500. The first drainage body 620 directly below the first separation component 400 does not have a drip hole, and the second drainage body 630 directly below the second separation component 500 has a drip hole. The structure is arc-shaped. The arc structure has two functions: first, it is conducive to the droplets to return to the liquid storage area through the first through hole 610, and second, the gas brought into the liquid storage area flows out through the arc-shaped side hole and is guided into the second separation component 500 along the arc surface.

[0068] Specifically, in the primary separation process of gas and liquid, the gas and liquid pass through the steam inlet channel 100 on the first separation component, and the high-speed flow hits the top of the first separation component 410 to evenly spread the gas and liquid to the surroundings. Under a certain flow rate, the evenly spread gas and liquid obliquely hit the cylindrical filter (first filter component 430) to simultaneously produce gas-liquid separation, and the gas quickly flows out through the second support component 450. The separated liquid flows back to the liquid storage area 312 through the anti-shock liquid panel under the action of gravity;

[0069] Directly below the first separation component 400, the first drainage body 620 of the drainage component 600 has no holes in order to prevent the impact on the liquid surface or the gas carrying large liquid droplets from passing through the second separation component 500 to affect the separation efficiency, and to prevent the impact on the production fluctuation of the liquid surface from affecting the liquid level observed by the liquid level display. The separated liquid returns to the liquid storage area through the hole end of the anti-impact plate, and the gas with some small droplets is separated again through the secondary separator;

[0070] In the second separation component 500, the gas entrained with some small droplets passes through the first separation component 400 and the drainage component 600 and enters the multi-directional centrifugal separation impeller (centrifugal impeller 511) in the second separation component 500. Under the action of centrifugal force, the gas and liquid are separated again at the moment the gas leaves the centrifugal impeller. The liquid attached to the second filter component 530 returns to the liquid storage area along the four third through holes 541 on the third support component 540, and the pure gas flows out through the gas outlet channel 200.

[0071] The entire gas-liquid separation process of the separator is completed outside the container. There is no redundant structure inside the container except for the drainage components, which can greatly save the container space. The separator can be used in a variety of general structures such as oil separators, flashers, gas-liquid separators, oil tanks, etc., which is easy to select and use.

[0072] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0073] The gas-liquid separator according to the present application includes a steam inlet channel 100 and a gas outlet channel 200, and the gas-liquid separator also includes a storage body 300, a first separation component 400 and a second separation component 500. The storage body 300 has a storage cavity 310; the first separation component 400 is communicated with the steam inlet channel 100; the second separation component 500 is communicated with the gas outlet channel 200, and the second separation component 500 is arranged in parallel with the first separation component 400 on the storage body 300, and the first separation component 400 and the second separation component 500 are connected by the storage body 300. The cavity 310 is connected; the first separation component 400 includes a first separation part 410, which is arranged opposite to the inlet of the steam inlet channel 100 so that the gas-liquid mixture in the steam inlet channel 100 can be separated into gas and liquid by impacting the first separation part 410; the second separation component 500 includes a second separation part 510, which is rotatably arranged around a predetermined axis so that the gas-liquid mixture after the first gas-liquid separation flows through the second separation part 510, and the centrifugal force is used to perform a secondary gas-liquid separation. The steam inlet channel 100 and the gas outlet channel 200 serve as channels for gas to enter and gas to leave, respectively. A storage cavity 310 is formed inside the storage body 300 for temporarily storing the separated liquid. The first separation component 410 is used to perform preliminary gas-liquid separation by impact separation. The second separation component 510 can generate a strong centrifugal force during rotation to completely separate the fine droplets carried in the gas-liquid mixture after the first separation, which significantly improves the purity of the gas and the efficiency of gas-liquid separation. In addition, the gas-liquid separator is arranged outside the container, and the gas-liquid separation process is completed outside the container. It can be used as a universal separator for various types of gas-liquid mixtures.
