Description

Technical Field

[0001] The invention relates to the technical field of gas-liquid separation, in particular to a gas-liquid separator with high separation efficiency. Background Art

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

[0003] In the pipeline network for long-distance transmission of natural gas, due to the change of pressure in the pipeline, there is a phenomenon that the water vapor originally dissolved in the natural gas condenses into liquid water, so it is necessary to set a gas-liquid separator at a corresponding position according to the environment in the pipeline; the vortex gas-liquid separator used in the natural gas transmission pipeline network is common, which includes a cylindrical separator shell and a spiral ring plate. The gas-liquid fluid entering the separator is guided by the spiral ring plate and forms a vortex, so that a vortex area is formed inside. The liquid is thrown onto the inner wall and slides down with gravity by utilizing the characteristics of large centrifugal force, so as to achieve gas-liquid separation;

[0004] When natural gas passes through the separator, it separates gas and liquid in spiral flow. In addition to water, the condensed liquid often produces condensate (light hydrocarbons in natural gas condense when pressure decreases or temperature changes), which has less fluidity than water. In the cavity of the vortex gas-liquid separator, with the high-speed spiral movement of the gas, the water droplets and condensate adhering to the inner wall are easy to move along the spiral path on the inner wall of the cavity with the gas flow when their aggregated weight is small. Since the condensate has poor fluidity and its spiral movement greatly increases its sliding distance, it will adhere to the inner wall of the separator cavity for a long time. After a long time, a thick condensate coating layer is often attached to the inner wall of the separator cavity, which reduces the cross-sectional area of ​​the effective gas transportation in the cavity, and also causes the inner wall surface to be not smooth enough, and the fluidity of water droplets on its surface becomes poor, which further causes the inner wall surface to retain droplets, so that when the natural gas is discharged from the bottom of the spiral channel, it is easy to produce entrainment, resulting in poor gas-liquid separation effect of the separator.

[0005] In addition, long-term contact between water and condensate on the inner wall of the cavity will also form an emulsion, which further increases the thickness of the covering layer and forms a vicious circle. Summary of the invention

[0006] The purpose of the present invention is to provide a gas-liquid separator with high separation efficiency, which solves the problem that the condensate in the vortex gas-liquid separator in the natural gas pipeline network is easy to adhere to the inner wall to form an uneven covering layer, affecting the sliding of water droplets under gravity, resulting in water droplets on the surface, and the phenomenon of entrained water droplets when the natural gas is discharged, resulting in poor gas-liquid separation effect.

At this time, the cleaning mechanism is in a state of being able to rotate freely, and then the high-speed gas flowing in the L-shaped exhaust pipe drives the rotating wheel to rotate, and the rotating wheel drives the driving ring to rotate through the transmission mechanism, so that the spiral scraper slides on the inner surface of the cover body, thereby scraping off the condensate coating layer attached to the inner surface of the cover body, and the scraped condensate automatically slides down along the lower surface of the spiral scraper, and finally gathers in the funnel-shaped collection The inner side of the hood is used to regularly clean the inner wall of the hood, thereby avoiding the long-term accumulation of condensate on the inner wall of the hood; in addition, the cleaning mechanism only cleans the inner wall of the hood once when the automatic drainer drains water. Under normal circumstances, due to the limiting effect of the buckle claw on the lower protruding ring, the cleaning mechanism and the rotating wheel are in a stationary state. Therefore, under normal circumstances, 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 kinetic energy of the rotating wheel rotation. Furthermore, in normal gas transmission in the hood, the impact on the airflow flowing in the hood is small, thereby ensuring the internal pressure of the hood during normal use.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0033] Combination Figure 1-Figure 10 , a gas-liquid separator with high separation efficiency comprises a cover body 10, wherein both sides of the cover body 10 are respectively provided with an air inlet and an air outlet, an oblique baffle 13 is arranged between the air inlet and the air outlet inside the cover body 10, a ventilation pipe connected to the upper surface of the oblique baffle 13 is arranged on the lower surface of the oblique baffle 13, a spiral sleeve is arranged on the outer surface of the ventilation pipe with a spiral plate 12, and the gas introduced into the air inlet passes through the spiral plate 12 spirally to achieve the purpose of centrifugal separation of water and gas, and the water is thrown to the inner wall of the cover body 10 and slides down with gravity, and the gas after passing through is guided by the ventilation pipe to the air outlet for discharge, and a funnel-shaped collecting cover 15 is also arranged on the lower side of the cover body 10, and an automatic drainer 14 is connected to the lower side of the funnel-shaped collecting cover 15, and the water in the automatic drainer 14 is automatically drained when the water inside is full, and the ventilation pipe comprises an L-shaped exhaust pipe 11, which is connected to the air outlet, and an opening groove 111 is arranged at the turning part of the L-shaped exhaust pipe 11;

[0034] The inner wall of the cover body 10 is provided with a rotating cleaning mechanism 20 for cleaning the inner wall of the cover body 10 along the circumference of the spiral plate 12. The cleaning mechanism 20 includes two driving rings 21 that are rotatably embedded in the inner side of the cover body 10. A plurality of spiral scrapers 22 are fixedly connected to the inner surface of the two driving rings 21 in the circumferential direction. The spiral scrapers 22 are closely attached to the inner wall of the cover body 10.

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

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

[0037] Furthermore, natural gas enters the cover body 10 from the air inlet, flows in a spiral through the spiral plate 12, and is then drained to the air outlet through the L-shaped exhaust pipe 11 for discharge. During the process, water droplets and condensate entrained in the natural gas are thrown to the inner wall of the cover body 10 in the spiral motion, and continue to move in a spiral manner under the push of the spiral flowing gas. The condensate eventually tends to cover the inner wall of the cover body 10. After a long time, a thick condensate coating layer is often attached to the inner wall of the separator cavity, which reduces the cross-sectional area of ​​the effective gas transmission in the cavity and causes the inner wall surface to be not smooth enough, and the fluidity of water droplets on its surface becomes poor. In this embodiment, by driving the trigger when the automatic drainer 14 drains water, The mechanism 50 releases the limiting effect on the cleaning mechanism 20. At this time, the cleaning mechanism 20 is in a state of free rotation. The high-speed gas flowing in the L-shaped exhaust pipe 11 drives the rotating wheel 31 to rotate. The rotation of the rotating wheel 31 drives the driving ring 21 to rotate through the transmission mechanism 40, so that the spiral scraper 22 slides on the inner surface of the cover body 10, thereby scraping off the condensate coating layer attached to the inner surface of the cover body 10. The scraped condensate automatically slides down along the lower surface of the spiral scraper 22, and finally gathers on the inner side of the funnel-shaped collecting cover 15, thereby achieving the effect of regularly cleaning the inner wall of the cover body 10 and avoiding the long-term accumulation of condensate on the inner wall of the cover body 10.

[0038] In the previous embodiment: the rotation direction of the drive ring 21 is opposite to the spiral direction of the spiral plate 12. Therefore, when the spiral scraper 22 rotates to scrape the inner wall of the cover body 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 flow of the airflow facilitates the condensate to be blown down along the lower surface of the spiral scraper 22. On the other hand, the spiral scraper 22 can play an isolation effect, preventing the spiral flow of the airflow from blowing the condensate that has not been cleaned on the inner wall of the cover body 10 into the clean area that has just been cleaned, causing repeated contamination.

[0039] In the previous embodiment: the opening slot 111 is adapted to the curvature of the rotating wheel 31, and the arc surface of the rotating wheel 31 protrudes into the cavity of the L-shaped exhaust pipe 11 through the opening slot 111. Stoppers 112 fixedly connected to the L-shaped exhaust pipe 11 are also provided on both sides of the opening slot 111, and the stoppers 112 are adapted to the curvature of the wind blowing slot 32;

[0040] Furthermore, when natural gas flows at a high speed in the L-shaped exhaust pipe 11, it will act on the wind blowing groove 32 on the arc surface of the rotating wheel 31 through the turning part of the L-shaped exhaust pipe 11, thereby pushing the rotating wheel 31 to rotate. The opening groove 111 is adapted to the arc of the rotating wheel 31, and the block 112 is adapted to the arc of the rotating wheel 31, so as to reduce the connection gap between the rotating wheel 31 and the L-shaped exhaust pipe 11 during rotation, so as to prevent excessive escape of gas and cause additional loss of gas flow rate in the L-shaped exhaust pipe 11.

[0041] In the previous embodiment: the rotating wheel 31 is rotatably mounted on the inner side of the cover body 10 through the rotating shaft, and one side of the rotating wheel 31 is also coaxially fixedly connected with the first gear 33, 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 transmission-connected through a crown gear, one end of the first rotating shaft 41 is connected with a second gear 411, and the second gear 411 is transmission-connected with the first gear 33, and the outer surface of the cover body 10 is provided with a sealing cover 44 for sealingly mounting the first rotating shaft 41 and the second rotating shaft 42;

[0042] Furthermore, the airflow in the L-shaped exhaust pipe 11 drives the rotating wheel 31 to rotate, and then the first gear 33 drives the second gear 411 to rotate, and further the second rotating shaft 42 rotates. The gear diameter of the second gear 411 is larger than the gear diameter 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 to the two driving rings 21 one by one, and the side surface of the driving ring 21 is provided with teeth 211 meshing with the third gears 43;

[0044] Furthermore, when the second rotating shaft 42 rotates, the two driving rings 21 are driven to rotate synchronously through two third gears 43 coaxially arranged with the second rotating shaft 42, driving the spiral scraper 22 to slide on the inner wall of the cover body 10, thereby avoiding the two driving rings 21 from rotating asynchronously, thereby causing the spiral scraper 22 to deform and not fit tightly enough with the inside of the cover body 10.

[0045] In the previous embodiment: the trigger mechanism 50 includes a combination block 51 integrally arranged on one side of the funnel-shaped collecting cover 15, a Z-shaped water channel 52 communicating with the lower side of the funnel-shaped collecting cover 15 is provided in the combination block 51, and the automatic drainer 14 is connected to the lower side 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 drain 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 clamping spring A533 is sleeved on the surface of the first rotating rod 531 to keep the touch plate 53 horizontal under normal conditions. A second rotating rod 54 is also vertically rotatably installed in the assembly block 51. A sector gear 543 meshing with the threaded column 532 is fixedly provided at the lower end of the second rotating rod 54. A buckle claw 541 is fixedly connected to the upper end of the second rotating rod 54.

[0047] A downwardly protruding lower ring 23 is provided on the lower surface close to the lower spiral scraper 22, and a buckle groove 231 is provided on the side surface of the lower protruding ring 23 for movably engaging with the buckle claw 541. A reset spring B542 is sleeved on the surface of the second rotating rod 54 for driving the buckle claw 541 to be embedded in the buckle groove 231 under normal conditions;

[0048] Furthermore, when the funnel-shaped collecting cover 15 collects water sliding down the inner wall of the cover body 10, the water will first gather in the low-lying area of ​​the Z-shaped water channel 52. As the liquid level gradually rises, after overflowing the highest position in the cavity of the Z-shaped water channel 52, it will slowly flow to the inside of the automatic drain 14. When the liquid level in the cover of the automatic drain 14 is filled, it automatically opens the valve to drain the liquid. At this time, the automatic drain 14 is connected to the normal atmospheric environment outside. At this time, the high-pressure gas inside the cover body 10 will push the liquid collected in the low-lying area inside the Z-shaped water channel 52 toward the direction of the automatic drain 14 at high speed. When the high-speed flowing liquid contacts the horizontally arranged touch plate 53, it will push it downward, prompting the first rotary The rod 531 rotates, and a storage cavity 521 for storing the touch plate 53 is opened on the inner wall of the Z-shaped water trough 52. The rotating first rotating rod 531 drives the fan-shaped gear 543 through the threaded column 532, prompting the second rotating rod 54 to rotate a certain angle. When the second rotating rod 54 rotates, the buckle claw 541 is separated from the inner side of the buckle groove 231, and the spiral scraper 22 can rotate freely. After the spiral scraper 22 rotates one circle, the buckle claw 541 will automatically buckle into the buckle groove 231 again to fix the spiral scraper 22. After the liquid in the cavity of the Z-shaped water trough 52 is discharged through the automatic drain 14, the automatic drain 14 is automatically closed, and the Z-shaped water trough 52 enters the next cycle of collecting liquid.

[0049] Through the above design, the cleaning mechanism 20 cleans the inner wall of the cover body 10 only once when the automatic drainer 14 drains water. Under normal circumstances, due to the limiting effect of the buckle 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 circumstances, 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 kinetic energy for the rotation of the rotating wheel 31. Furthermore, in normal gas supply in the cover body 10, the above structure has little effect on the airflow flowing in the cover body 10, thereby ensuring the internal pressure of the cover body 10 during normal use.

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

[0051] In the previous embodiment: an air hole 55 is provided on the inner wall of the Z-shaped water trough 52, near the top at the highest position. The air hole 55 is connected to the inner side of the funnel-shaped collecting cover 15 in a "7" shape. A truncated cone groove 551 is provided on one side of the air hole 55 near the inner side of the Z-shaped water trough 52. The truncated cone groove 551 is narrow at the top and wide at the bottom. A sealing ball 552 is provided in the truncated cone groove 551 to block the air hole 55 upward. A lifting ring 553 is provided on the lower side of the sealing ball 552 to lift it higher than the bottom surface of the truncated cone groove 551.

[0052] Furthermore, in the liquid gathered in the low-lying area of ​​the Z-shaped water trough 52, the air holes 55 can discharge the gas at the top of the Z-shaped water trough 52 cavity into the funnel-shaped collecting cover 15, so as to prevent the residual gas at the top of the Z-shaped water trough 52 cavity from hindering the liquid in the Z-shaped water trough 52 from flowing toward the automatic drainer 14. When the automatic drainer 14 is turned on for drainage, when the water flowing in the Z-shaped water trough 52 flows into the inner side of the conical groove 551, the sealing ball 552 will be pushed up to prevent the liquid from excessively entering the air holes 55 and affecting the discharge of the liquid.

[0053] Working principle: The funnel-shaped collecting cover 15 collects the water sliding down the inner wall of the cover body 10, and the water is first collected in the low-lying part of the Z-shaped water channel 52. As the liquid level rises, after overflowing the highest position in the cavity of the Z-shaped water channel 52, it slowly flows to the inside of the automatic drain 14. As the liquid level in the cover of the automatic drain 14 is filled, it automatically opens the valve to drain the liquid. At this time, the high-pressure gas inside the cover body 10 will push the liquid collected in the low-lying part inside the Z-shaped water channel 52 toward the direction of the automatic drain 14 at a 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 fan gear 543 through the threaded column 532, causing the second rotating rod 54 to rotate a certain angle. At this time, the buckle claw 541 is separated from the inner side of the buckle groove 231, and the spiral scraper 22 can rotate freely.

[0054] The high-speed gas flowing in the L-shaped exhaust pipe 11 drives the rotating wheel 31 to rotate, and then the first gear 33 drives the second gear 411 to rotate, and further the second rotating shaft 42 rotates. When the second rotating shaft 42 rotates, the two driving rings 21 are driven to rotate synchronously through two third gears 43 coaxially arranged with the second rotating shaft 42, and the spiral scraper 22 is driven to slide on the inner wall of the cover body 10 to scrape off the condensate coating layer attached to the inner surface of the cover body 10;

[0055] When the spiral scraper 22 rotates one circle, the buckle claw 541 will automatically buckle into the buckle groove 231 again to fix the spiral scraper 22.
