A gas-liquid separator with high separation efficiency

Abstract

This invention relates to the field of gas-liquid separation technology and discloses a high-efficiency gas-liquid separator. It solves the problem in natural gas pipelines where condensate easily adheres to the inner wall of the gas-liquid separator, forming an uneven coating that affects the downward movement of water droplets under gravity, resulting in poor gas-liquid separation. When the automatic drainer drains water, it triggers the release of the limiting effect on the cleaning mechanism, allowing the cleaning mechanism to rotate freely. The high-speed gas flow in the L-shaped exhaust pipe drives the rotating wheel to rotate, which in turn drives the drive ring through a transmission mechanism. This causes the spiral scraper to slide on the inner surface of the enclosure, scraping off the condensate coating. The scraped condensate automatically slides down the lower surface of the spiral scraper and eventually collects inside the funnel-shaped collection hood, thus achieving the effect of periodically cleaning the inner wall of the enclosure and preventing the long-term accumulation of condensate on the inner wall.

Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation technology, specifically to a gas-liquid separator with high separation efficiency. Background Technology

[0002] A gas-liquid separator is an industrial device used to effectively separate a mixture of gas and liquid phases in a pipeline or equipment.

[0003] In natural gas transmission pipelines, due to pressure changes within the pipeline, water vapor originally dissolved in the natural gas may condense into liquid water. Therefore, gas-liquid separators need to be installed at appropriate locations based on the pipeline environment. A common type used in natural gas transmission pipelines is the vortex gas-liquid separator, which includes a cylindrical separator shell and a spiral annular plate. The gas and liquid fluids entering the separator are guided by the spiral annular plate and form a vortex, creating an internal vortex region. Utilizing the centrifugal force of the liquid, the fluid is thrown against the inner wall and slides down under gravity, thus achieving gas-liquid separation.

[0004] When natural gas passes through a separator, the spiral flow separation of gas and liquid often produces condensate (light hydrocarbons in natural gas condense when pressure decreases or temperature changes) in addition to water. Its fluidity is less than that of water. In the chamber of a vortex gas-liquid separator, as the gas moves in a high-speed spiral motion, water droplets and condensate adhering to the inner wall, when their accumulated weight is small, easily move along the spiral path of the airflow along the inner wall of the chamber. Due to the poor fluidity of the condensate and its spiral movement, its sliding distance is greatly increased, causing it to adhere to the inner wall of the separator chamber for a longer period of time. Over time, a thick layer of condensate often adheres to the inner wall of the separator chamber. This not only reduces the cross-sectional area of ​​the gas that can be effectively transported in the chamber, but also makes the inner wall surface uneven. The fluidity of water droplets on its surface decreases, further causing droplets to remain on the inner wall surface. This makes it easy for natural gas to be entrained when it is discharged from the bottom of the spiral channel, resulting in poor gas-liquid separation effect of the separator.

[0005] In addition, prolonged contact between water and condensate on the inner wall of the cavity can form emulsions, which further increases the thickness of the coating layer, creating a vicious cycle. Summary of the Invention

[0006] The purpose of this invention is to provide a gas-liquid separator with high separation efficiency, which solves the problem that in natural gas pipelines, condensate in vortex gas-liquid separators tends to adhere to the inner wall to form an uneven coating layer, which affects the downward sliding of water droplets under gravity, resulting in water droplets remaining on the surface. When natural gas is discharged, water droplets are easily entrained, causing poor gas-liquid separation effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency gas-liquid separator, comprising a cover, an air inlet and an air outlet respectively provided on both sides of the cover, an inclined baffle provided between the air inlet and the air outlet on the inner side of the cover, a vent pipe connected to the upper surface of the inclined baffle provided on the lower surface of the inclined baffle, a spiral plate spirally sleeved on the outer surface of the vent pipe, gas introduced through the air inlet spirally passes through the spiral plate and is then guided by the vent pipe to be discharged from the air outlet, a funnel-shaped collection cover is also provided on the lower side of the cover, an automatic drainer is connected to the lower side of the funnel-shaped collection cover, the vent pipe includes an L-shaped exhaust pipe, the L-shaped exhaust pipe is connected to the air outlet, and an opening groove is provided at the bend of the L-shaped exhaust pipe;

[0008] The inner wall of the cover is provided with a rotating cleaning mechanism for cleaning the inner wall of the cover along the circumference of the spiral plate. The cleaning mechanism includes two drive rings that are rotatably embedded in the inner side of the cover. Several spiral scrapers are fixedly connected to the inner surface of the two drive rings in a circumferential direction. The spiral scrapers are in close contact with the inner wall of the cover.

[0009] The upper side of the opening slot is provided with a drive mechanism driven by the airflow inside the L-shaped exhaust pipe. The side of the cover is also provided with a transmission mechanism for linking the drive mechanism and the cleaning mechanism. The drive mechanism includes a rotating wheel, which is compactly arranged on one side of the opening slot. The surface of the rotating wheel is provided with a wind blowing groove.

[0010] A trigger mechanism for rotating the movable limiting cleaning mechanism is provided on one side of the funnel-shaped collection hood. The automatic drainer is connected to the funnel-shaped collection hood through the trigger mechanism. When the automatic drainer drains water, the trigger mechanism disconnects the limit of the cleaning mechanism. In this state, the rotating wheel drives the drive ring to rotate through the transmission mechanism, and the spiral scraper slides circumferentially along the inner wall of the hood.

[0011] As a further description of the above technical solution: the rotation direction of the drive ring is opposite to the helical direction of the spiral plate.

[0012] As a further description of the above technical solution: the opening groove is adapted to the curvature of the rotating wheel, the arc surface of the rotating wheel protrudes into the L-shaped exhaust pipe cavity through the opening groove, and the two sides of the opening groove are also provided with baffles that are fixedly connected to the L-shaped exhaust pipe, the baffles being adapted to the curvature of the air blowing groove.

[0013] As a further description of the above technical solution: the rotating wheel is rotatably mounted inside the cover via a rotating shaft, and a first gear is coaxially fixedly connected to one side of the rotating wheel. The transmission mechanism includes a horizontally arranged first rotating shaft and a vertically arranged second rotating shaft. One end of the first rotating shaft and the second rotating shaft are connected by a crown gear. One end of the first rotating shaft is connected to the second gear, and the second gear is connected to the first gear. The outer surface of the cover is provided with a sealing cover for sealing and mounting the first rotating shaft and the second rotating shaft.

[0014] As a further description of the above technical solution: two third gears are coaxially arranged on the surface of the second rotating shaft, and the two third gears correspond one-to-one with the two drive rings. The side surface of the drive ring is provided with meshing teeth that mesh with the third gears.

[0015] As a further description of the above technical solution: the triggering mechanism includes a combined block integrally disposed on one side of the funnel-shaped collection hood, the combined block having a Z-shaped water channel communicating with the lower side of the funnel-shaped collection hood, and the automatic drainer being connected to the lower opening of the Z-shaped water channel.

[0016] As a further description of the above technical solution: A touch plate is rotatably installed on the inner wall of the Z-shaped water channel and above the automatic drainer. A first rotating rod is fixedly connected to one side of the touch plate. The first rotating rod is rotatably installed inside the assembly block. A threaded column is fixedly connected to one end of the first rotating rod. A reset snap ring A that keeps the touch plate horizontal under normal conditions is sleeved on its surface. A second rotating rod is also rotatably installed vertically inside the assembly block. A sector gear that meshes with the threaded column is fixedly provided at the lower end of the second rotating rod. A latch is fixedly connected to the upper end of the second rotating rod.

[0017] As a further description of the above technical solution: a downward protruding ring is provided on the lower surface near the spiral scraper below, and a buckle groove is opened on the side surface of the lower protruding ring to movably engage with the buckle claw. A reset snap ring B is sleeved on the surface of the second rotating rod to drive the buckle claw to embed into the buckle groove under normal conditions.

[0018] As a further description of the above technical solution: an air vent is provided on the inner wall of the Z-shaped water channel cavity near the highest point. The air vent is connected to the inner side of the funnel-shaped collection cover in the shape of a "7". A frustum groove is provided on the side of the air vent near the inner side of the Z-shaped water channel cavity. The frustum groove is narrow at the top and wide at the bottom. A sealing ball is provided in the frustum groove to block the air vent upward. A lifting ring is provided on the lower side of the sealing ball to support it above the bottom surface of the frustum groove.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this invention are as follows: When the automatic drainer drains water, it causes the triggering mechanism to release the limiting effect on the cleaning mechanism. At this time, the cleaning mechanism is in a state of free rotation. Then, the high-speed gas flowing in the L-shaped exhaust pipe drives the rotating wheel to rotate. The rotating wheel drives the drive ring to rotate through the transmission mechanism, thereby causing the spiral scraper to slide on the inner surface of the cover, thereby scraping off the condensate coating layer attached to the inner surface of the cover. The scraped condensate automatically slides down the lower surface of the spiral scraper and finally collects in the funnel-shaped collection. The cleaning mechanism cleans the inner wall of the hood periodically, preventing the accumulation of condensate on the inner wall over a long period. Furthermore, the cleaning mechanism only cleans the inner wall of the hood once when the automatic drainer drains water. Under normal conditions, due to the limiting effect of the latch on the lower protruding ring, both the cleaning mechanism and the rotating wheel are stationary. Therefore, under normal conditions, the work done by the gas flowing in the L-shaped exhaust pipe on the surface of the rotating wheel will not be converted into the kinetic energy of the rotating wheel. Furthermore, during normal gas delivery within the hood, the impact on the airflow within the hood is minimal, thus ensuring the internal pressure of the hood during normal use.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0033] Combination Figures 1-10 A high-efficiency gas-liquid separator includes a cover 10, with an air inlet and an air outlet on both sides of the cover 10. An inclined baffle 13 is provided between the air inlet and the air outlet on the inner side of the cover 10. A vent pipe is provided on the lower surface of the inclined baffle 13 and connected to the upper surface of the inclined baffle 13. A spiral plate 12 is spirally sleeved on the outer surface of the vent pipe. Gas is introduced through the air inlet and spirally passes through the spiral plate 12 to achieve centrifugal separation of water and gas. Water is thrown to the inner wall of the cover 10 and slides down with gravity. The gas that has passed through is then guided to the air outlet through the vent pipe and discharged. A funnel-shaped collection cover 15 is also provided on the lower side of the cover 10. An automatic drainer 14 is connected to the lower side of the funnel-shaped collection cover 15. When the water inside the automatic drainer 14 is full, it automatically drains water. The vent pipe includes an L-shaped exhaust pipe 11, which is connected to the air outlet. An opening groove 111 is opened at the bend of the L-shaped exhaust pipe 11.

[0034] The inner wall of the cover 10 is provided with a rotating cleaning mechanism 20 for cleaning the inner wall of the cover 10 along the circumference of the spiral plate 12. The cleaning mechanism 20 includes two drive rings 21 that are rotatably embedded in the inner side of the cover 10. Several spiral scrapers 22 are fixedly connected to the inner surface of the two drive rings 21 in a circumferential manner. The spiral scrapers 22 are in close contact with the inner wall of the cover 10.

[0035] A drive mechanism 30 driven by the airflow inside the L-shaped exhaust pipe 11 is provided on the upper side of the opening slot 111. A transmission mechanism 40 for linking the drive mechanism 30 and the cleaning mechanism 20 is also provided on one side of the cover 10. The drive mechanism 30 includes a rotating wheel 31, which is compactly located on one side of the opening slot 111. A wind blowing groove 32 is opened on the surface of the rotating wheel 31.

[0036] A trigger mechanism 50 for rotating the movable limiting cleaning mechanism 20 is provided on one side of the funnel-shaped collection cover 15. The automatic drainer 14 is connected to the funnel-shaped collection cover 15 through the trigger mechanism 50. When the automatic drainer 14 drains water, the trigger mechanism 50 disconnects the limiting of the cleaning mechanism 20. In this state, the rotating wheel 31 drives the drive ring 21 to rotate through the transmission mechanism 40, and the spiral scraper 22 slides circumferentially along the inner wall of the cover 10.

[0037] Furthermore, natural gas enters the enclosure 10 through the inlet, flows spirally through the spiral plate 12, and is then discharged through the L-shaped exhaust pipe 11 to the outlet. During this process, water droplets and condensate entrained in the natural gas are thrown onto the inner wall of the enclosure 10 during the spiral motion and continue to move spirally under the push of the spiral flow of gas. The condensate eventually fills the inner wall of the enclosure 10. Over time, a thick layer of condensate often adheres to the inner wall of the separator cavity. This not only reduces the cross-sectional area of ​​the gas effectively transported in the cavity but also makes the inner wall surface uneven, reducing the fluidity of water droplets on its surface. In this embodiment, the automatic drainer 14 is activated when draining water. The mechanism 50 releases its limiting effect on the cleaning mechanism 20, allowing the cleaning mechanism 20 to rotate freely. The high-speed gas flow in the L-shaped exhaust pipe 11 drives the rotating wheel 31 to rotate. The rotation of the rotating wheel 31 drives the drive ring 21 to rotate through the transmission mechanism 40, thereby causing the spiral scraper 22 to slide on the inner surface of the cover 10. This scrapes off the condensate coating layer attached to the inner surface of the cover 10. The scraped condensate automatically slides down the lower surface of the spiral scraper 22 and eventually collects inside the funnel-shaped collection cover 15, thus achieving the effect of periodically cleaning the inner wall of the cover 10 and preventing the condensate from accumulating on the inner wall of the cover 10 for a long time.

[0038] In the previous embodiment, the rotation direction of the drive ring 21 is opposite to the spiral direction of the spiral plate 12. As such, when the spiral scraper 22 rotates to scrape off the inner wall of the cover 10, it will face the direction of the airflow. On the one hand, when the spiral scraper 22 scrapes off the condensate covering layer, the spiral airflow makes it easy to blow the condensate down along the lower surface of the spiral scraper 22. On the other hand, the spiral scraper 22 can play an isolation role, preventing the spiral airflow from blowing the condensate that has not yet been cleaned from the inner wall of the cover 10 into the clean area that has just been cleaned, thus causing repeated contamination.

[0039] In the previous embodiment: the opening groove 111 is adapted to the curvature of the rotating wheel 31, the arc surface of the rotating wheel 31 protrudes into the cavity of the L-shaped exhaust pipe 11 through the opening groove 111, and the two sides of the opening groove 111 are also provided with stop blocks 112 that are fixedly connected to the L-shaped exhaust pipe 11, and the stop blocks 112 are adapted to the curvature of the air blowing groove 32.

[0040] Furthermore, as the natural gas flows at high speed within the L-shaped exhaust pipe 11, it passes through the bend of the L-shaped exhaust pipe 11 and acts on the air-blowing groove 32 on the arc surface of the rotating wheel 31, thereby driving the rotating wheel 31 to rotate. The arrangement of the opening groove 111 and the arc of the rotating wheel 31, as well as the arrangement of the stop block 112 and the arc of the rotating wheel 31, reduces the connection gap between the rotating wheel 31 and the L-shaped exhaust pipe 11 during rotation, so as to prevent excessive gas escape and additional loss of gas flow velocity within the L-shaped exhaust pipe 11.

[0041] In the previous embodiment: the rotating wheel 31 is rotatably mounted inside the cover 10 via a rotating shaft. A first gear 33 is also coaxially fixedly connected to one side of the rotating wheel 31. The transmission mechanism 40 includes a horizontally arranged first rotating shaft 41 and a vertically arranged second rotating shaft 42. One end of the first rotating shaft 41 and the second rotating shaft 42 are connected by a crown gear. One end of the first rotating shaft 41 is connected to the second gear 411. The second gear 411 is connected to the first gear 33. The outer surface of the cover 10 is provided with a sealing cover 44 for sealing the installation of the first rotating shaft 41 and the second rotating shaft 42.

[0042] Furthermore, the airflow inside the L-shaped exhaust pipe 11 drives the rotating wheel 31 to rotate, which in turn causes the first gear 33 to drive the second gear 411 to rotate, further causing the second rotating shaft 42 to rotate. The gear diameter of the second gear 411 is larger than that of the first gear 33, so that the first gear 33 can drive the second gear 411 to rotate with less effort.

[0043] In the previous embodiment: two third gears 43 are coaxially arranged on the surface of the second rotating shaft 42, and the two third gears 43 correspond one-to-one with the two drive rings 21. The side surface of the drive ring 21 is provided with meshing teeth 211 that mesh with the third gears 43.

[0044] Furthermore, when the second rotating shaft 42 rotates, the two driving rings 21 are driven to rotate synchronously by two third gears 43 coaxially arranged with the second rotating shaft 42, which causes the spiral scraper 22 to slide on the inner wall of the cover 10. This can prevent the two driving rings 21 from rotating asynchronously, which would cause the spiral scraper 22 to deform and not fit tightly enough with the inside of the cover 10.

[0045] In the previous embodiment: the triggering mechanism 50 includes a combination block 51 integrally disposed on one side of the funnel-shaped collection cover 15. A Z-shaped water channel 52 communicating with the lower side of the funnel-shaped collection cover 15 is opened in the combination block 51. The automatic drainer 14 is connected to the lower opening of the Z-shaped water channel 52.

[0046] A touch plate 53 is rotatably installed on the inner wall of the Z-shaped water channel 52 and above the automatic drainer 14. A first rotating rod 531 is fixedly connected to one side of the touch plate 53. The first rotating rod 531 is rotatably installed inside the assembly block 51. A threaded column 532 is fixedly connected to one end of the first rotating rod 531. A reset snap ring A533, which normally keeps the touch plate 53 horizontal, is sleeved on its surface. A second rotating rod 54 is also rotatably installed vertically inside the assembly block 51. A sector gear 543 that meshes with the threaded column 532 is fixedly provided at the lower end of the second rotating rod 54. A latch 541 is fixedly connected to the upper end of the second rotating rod 54.

[0047] A downward protruding ring 23 is provided on the lower surface near the lower spiral scraper 22. A buckle groove 231 is provided on the side surface of the lower protruding ring 23 to be movably fitted with the buckle claw 541. A reset snap ring B542 is sleeved on the surface of the second rotating rod 54 to drive the buckle claw 541 to be embedded in the buckle groove 231 under normal conditions.

[0048] Furthermore, when the funnel-shaped collecting hood 15 collects water sliding down the inner wall of the hood 10, the water will preferentially collect in the low-lying area of ​​the Z-shaped water channel 52. As the liquid level slowly rises, after overflowing the highest point in the Z-shaped water channel 52 cavity, it will slowly flow to the inside of the automatic drain 14. When the liquid level inside the automatic drain 14 is full, it automatically opens the valve to drain the liquid. At this time, the automatic drain 14 is connected to the normal atmospheric environment. Then, the high-pressure gas inside the hood 10 will push the liquid collected in the low-lying area inside the Z-shaped water channel 52 towards the automatic drain 14 at high speed. When the high-speed flowing liquid comes into contact with the horizontally set touch plate 53, it will push it downward, causing the first rotation. When rod 531 rotates, the inner wall of the Z-shaped water channel 52 is provided with a storage cavity 521 for storing the touch plate 53. The rotating first rod 531 will drive the sector gear 543 through the threaded column 532, causing the second rod 54 to rotate at a certain angle. When the second rod 54 rotates, the pawl 541 will disengage from the inner side of the slot 231. At this time, the spiral scraper 22 can rotate freely. After the spiral scraper 22 rotates one revolution, the pawl 541 will automatically engage with the slot 231 again to fix the spiral scraper 22. After the liquid in the Z-shaped water channel 52 cavity is discharged through the automatic drainer 14, the automatic drainer 14 will automatically close, and the Z-shaped water channel 52 will enter the next cycle of collecting liquid.

[0049] With the above design, the cleaning mechanism 20 cleans the inner wall of the cover 10 only once when the automatic drainer 14 drains water. Under normal conditions, due to the limiting effect of the latch 541 on the lower protruding ring 23, the cleaning mechanism 20 and the rotating wheel 31 are both in a stationary state. Therefore, under normal conditions, the work done by the gas flowing in the L-shaped exhaust pipe 11 on the surface of the rotating wheel 31 will not be converted into the kinetic energy of the rotating wheel 31. Furthermore, during normal gas supply in the cover 10, the above structure has little impact on the airflow flowing in the cover 10, thereby ensuring the internal pressure of the cover 10 during normal use.

[0050] It should be noted that the automatic drainer 14 automatically drains liquid when it is filled with liquid and automatically closes the valve after the liquid is drained. Existing automatic drainers can achieve this effect, such as float-type automatic drainers and SMC automatic drainers.

[0051] In the previous embodiment: an air vent 55 is provided on the inner wall of the Z-shaped water channel 52 near the highest point. The air vent 55 is connected to the inner side of the funnel-shaped collection cover 15 in a "7" shape. A frustum groove 551 is provided on the side of the air vent 55 near the inner side of the Z-shaped water channel 52. The frustum groove 551 is narrow at the top and wide at the bottom. A sealing ball 552 is provided in the frustum groove 551 to block the air vent 55 upward. A lifting ring 553 is provided on the lower side of the sealing ball 552 to support it above the bottom surface of the frustum groove 551.

[0052] Furthermore, in the low-lying area of ​​the Z-shaped water channel 52, where liquid gathers, the vent 55 can discharge the gas at the top of the Z-shaped water channel 52 into the funnel-shaped collection hood 15. This prevents the gas remaining at the top of the Z-shaped water channel 52 from obstructing the flow of liquid in the Z-shaped water channel 52 toward the automatic drain 14. When the automatic drain 14 is in the draining state, when the water flowing in the Z-shaped water channel 52 rushes into the inner side of the frustum groove 551, it will push the sealing ball 552 upward to prevent excessive liquid from entering the vent 55 and affecting the discharge of liquid.

[0053] Working principle: The funnel-shaped collection hood 15 collects water that slides down the inner wall of the hood body 10. The water first gathers in the low-lying area of ​​the Z-shaped water channel 52. As the liquid level rises, it overflows the highest point in the Z-shaped water channel 52 and then slowly flows to the inside of the automatic drainer 14. When the liquid level in the automatic drainer 14 is full, it automatically opens the valve to drain the liquid. At this time, the high-pressure gas inside the hood body 10 will push the liquid gathered in the low-lying area inside the Z-shaped water channel 52 towards the automatic drainer 14 at high speed. The high-speed flowing liquid pushes the touch plate 53 downward, causing the first rotating rod 531 to rotate. The rotating first rotating rod 531 drives the sector gear 543 through the threaded column 532, causing the second rotating rod 54 to rotate at a certain angle. At this time, the latch 541 disengages from the inside of the latch groove 231, and the spiral scraper 22 can rotate freely.

[0054] The high-speed gas flow in the L-shaped exhaust pipe 11 drives the rotating wheel 31 to rotate, which in turn drives the first gear 33 to rotate the second gear 411, which in turn drives the second shaft 42 to rotate. When the second shaft 42 rotates, the two drive rings 21 are driven to rotate synchronously by the two third gears 43 that are coaxial with the second shaft 42, which drives the spiral scraper 22 to slide on the inner wall of the cover 10 to scrape off the condensate coating layer attached to the inner surface of the cover 10.

[0055] After the spiral scraper 22 rotates one revolution, the locking claw 541 will automatically lock into the locking groove 231 again to fix the spiral scraper 22.
