Description

Technical Field

[0001] This invention belongs to the field of natural gas processing technology, and specifically relates to a natural gas gas-liquid separation device. Background Technology

[0002] Natural gas, as a clean and efficient energy source, inevitably carries liquid phases during its extraction, gathering, and transportation processes. This is particularly evident in the pretreatment of natural gas in marine engineering. The complex offshore extraction environment and the large fluctuations in the composition of the gas and liquid media mean that the entrained liquid phases not only contain formation water and condensate oil but may also carry high-salinity impurities. If these are not effectively separated, they can cause serious corrosion, wear, and blockages to subsequent pipelines, compressors, and liquefaction equipment, directly affecting the stable operation of the liquefaction process and the quality of the final product, severely restricting the efficient development and utilization of offshore natural gas resources. If the separation is incomplete, subsequent combustion can easily generate particulate matter, sulfides, and other air pollutants, leading to a chain of problems such as air and water pollution. Therefore, efficient gas-liquid separation is a crucial step in natural gas processing.

[0003] Currently, most industrial natural gas separation devices are centrifugal separators. Their core principle is to use the centrifugal force generated by high-speed rotation to separate gas and liquid with different densities. Existing separators mostly have fixed-diameter inlet designs, which cannot adjust the effective flow area in real time according to fluctuations in natural gas feed pressure and flow rate. When the feed pressure suddenly increases, the internal pressure of the separator is easily too high due to insufficient flow, which may lead to the risk of seal leakage. On the other hand, when the feed pressure suddenly drops, the excessive flow will affect the stability of the centrifugal separation flow field, making it difficult to guarantee the separation effect under complex operating conditions. Therefore, it is necessary to design a natural gas gas-liquid separation device. Summary of the Invention

[0004] The purpose of this invention is to provide a natural gas gas-liquid separation device with a simple structure and reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A natural gas gas-liquid separation device includes a lower support, on which support seats are symmetrically arranged. An outer shell is rotatably connected to the support seats. A transmission sleeve is rotatably connected to one end of the outer shell. The transmission sleeve is fixedly connected to an inner shell. A flow rate adjustment mechanism is provided on the transmission sleeve. A liquid phase outlet is uniformly opened at one end of the outer shell, and a liquid outlet adjustment mechanism is provided on the side of the outer shell with the liquid phase outlet. The outer shell and the transmission sleeve are connected to a coaxial drive mechanism. The flow rate adjustment mechanism includes a distribution pipe arranged on the transmission sleeve. Spiral liquid distribution grooves are uniformly arranged on the side wall of the distribution pipe. An outer sleeve is slidably connected to the distribution pipe. A blocking component is uniformly arranged on the inner wall of the outer sleeve. The blocking component is slidably connected in the liquid distribution groove. A magnetic adaptation mechanism is provided on the outer sleeve.

[0006] As a further optimization of the present invention, the magnetic force adaptation mechanism includes a support sleeve slidably connected to the outer sleeve, a permanent magnet is provided in the support sleeve, an electromagnetic coil is embedded in the outer sleeve, and a limit tube is provided on the outer sleeve, the limit tube slidingly penetrating the support sleeve.

[0007] As a further optimization of the present invention, the support sleeve is fixed in the inner frame, the inner frame is fixed on the spiral guide frame, one end of the spiral guide frame is fixed on the inner shell, and the other end of the spiral guide frame is rotatably connected to the outer shell.

[0008] As a further optimization of the present invention, the liquid discharge adjustment mechanism includes a closed ring slidably connected to the side wall of the outer shell, a connecting groove is uniformly opened on the side wall of the outer shell, the closed ring is fitted onto the connecting groove, and a connecting plate is uniformly arranged on the inner wall of the closed ring.

[0009] As a further optimization of the present invention, the connecting plate is slidably connected in the communicating groove, and one end of the connecting plate is sleeved in the groove opened in the side wall of the sliding tube. The sliding tube is slidably connected in the outer shell, and one end of the sliding tube is rotatably connected to the limiting tube.

[0010] As a further optimization of the present invention, a transmission frame is rotatably connected to the closed ring, one end of the transmission frame is rotatably connected to the closed door, and the closed door is attached to the liquid phase outlet. The closed door is slidably connected to the support rail, and the support rail is fixed to the outer shell.

[0011] As a further optimization of the present invention, a solid discharge port is uniformly opened at the end of the outer shell away from the liquid phase outlet, and a closed cover is rotatably connected to the lower support. A partition plate is provided on the inner wall of the lower support and the closed cover.

[0012] As a further optimization of the present invention, a discharge hopper is provided at the bottom of the lower support near the solid discharge port, and a liquid discharge port is provided at the bottom of the lower support near the liquid phase outlet.

[0013] As a further optimization of the present invention, the coaxial drive mechanism includes a first roller fixed on the outer shell, a first motor fixedly mounted on the top of the lower support, a second roller fixedly connected to the output end of the first motor, and a first transmission belt tensioned on the first roller and the second roller.

[0014] As a further optimization of the present invention, a third roller is fixedly sleeved on one end of the transmission sleeve, a second motor is fixedly installed on the bottom of the lower support, the output end of the second motor is fixedly connected to a fourth roller, and a second transmission belt is tensioned on the fourth roller and the third roller.

[0015] The beneficial effects of this invention are as follows: 1. When the natural gas pressure increases, the increased pressure between the distribution pipe and the outer sleeve will push the outer sleeve outward. As the outer sleeve slides on the distribution pipe, the plugging component will slide along the liquid distribution groove opening, opening the liquid distribution groove opening blocked by the plugging component. This can cope with the working condition of sudden increase in feed flow rate and avoid excessive pressure in the inner shell due to insufficient flow. When the natural gas pressure decreases, the magnetic force will push the outer sleeve inward, blocking part of the liquid distribution groove opening through the plugging component, avoiding excessive flow under low pressure conditions from affecting the stability of the centrifugal separation flow field.

[0016] 2. The energized electromagnetic coil of this invention continuously generates heat, which exchanges heat with the natural gas flowing into the distribution pipe, preventing wax from precipitating in the natural gas and preventing liquid phase from adhering and clogging the distribution groove. During the process of natural gas pressure change, the clogging component will slide in the distribution groove, which will clean the distribution groove and further improve the anti-clogging effect.

[0017] 3. When the outer sleeve of this invention slides, it drives the fixedly connected limiting tube to move axially outward synchronously. The displacement of the limiting tube is transmitted to the sliding tube, pushing the sliding tube to slide axially along the outer shell. During the process, the connecting plate pulls the closing ring to slide synchronously along the side wall of the outer shell. During the movement of the closing ring, the transmission frame drives the closing door to change its position on the liquid phase outlet. After the open area of ​​the liquid distribution tank increases, resulting in an increase in the flux, the total amount of gas-liquid mixture entering the outer shell increases. The liquid phase outlet will adaptively close under the movement of the closing door, increasing the adaptability of the liquid phase thickness. This avoids insufficient flow field transmission due to an excessively high proportion of gas phase, which would prevent water molecules from obtaining sufficient centrifugal force. Conversely, after the open area of ​​the liquid distribution tank decreases, resulting in a decrease in the flux, the total amount of gas-liquid mixture entering the outer shell decreases. The liquid phase outlet will adaptively open under the movement of the closing door, decreasing the adaptability of the liquid phase thickness. This prevents the liquid phase layer from becoming too thick, which would create space for gas phase flow and cause cavitation effect, thus dispersing the liquid phase and ensuring the separation effect of the device.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Please refer to Figures 1-9A natural gas gas-liquid separation device includes a lower support 1, on which support seats 2 are symmetrically arranged. A housing 3 is rotatably connected to the support seats 2 via bearings. The support seats 2 provide rotational support for the housing 3 and limit the axial and radial displacement of the housing 3 to prevent eccentric swaying during rotation. A transmission sleeve 4 is rotatably connected to one end of the housing 3. The transmission sleeve 4 is fixedly connected to an inner housing 5, and the housing 3 is located inside the inner housing 5. A flow rate adjustment mechanism 6 is provided on the transmission sleeve 4. The flow rate adjustment mechanism 6 is used to adjust the effective flow area between the transmission sleeve 4 and the housing 3, thereby adjusting the flow rate of the gas-liquid mixture entering the housing 3 according to the pressure of the introduced natural gas. The cavity in the transmission sleeve 4 is used for... For the natural gas docking structure, the natural gas to be processed can be introduced into the inner shell 5. A liquid phase outlet 7 is uniformly provided at one end of the outer shell 3, serving as a discharge channel for the liquid phase. The separated liquid phase flows along the wall under centrifugal force and enters the space between the sealed cover 13 and the lower support 1 through the liquid phase outlet 7. A liquid discharge adjustment mechanism 8 is provided on the side of the outer shell 3 where the liquid phase outlet 7 is located. The liquid discharge adjustment mechanism 8 is used to adjust the exposure height of the liquid phase outlet 7, thereby controlling the liquid phase discharge rate and maintaining the thickness of the liquid phase layer inside the outer shell 3 to prevent the liquid phase layer from becoming too thin. The outer shell 3 and the transmission sleeve 4 are connected to a coaxial drive mechanism 9. A solid discharge port 12 is uniformly provided at the end of the outer shell 3 away from the liquid phase outlet 7. The lower support 1... A rotatable enclosure 13 is connected to the lower support 1. A partition plate 14 is provided on the inner wall of the enclosure 13. A discharge hopper 15 for discharging solid residue is provided at the bottom of the lower support 1 near the solid discharge port 12, and a drain port 16 for discharging separated liquid is provided at the bottom of the lower support 1 near the liquid phase outlet 7. During the operation of the separation device, the enclosure 13 covers the outside of the outer shell 3, forming a closed separation space with the lower support 1. At the same time, after sealing, the partition plate 14 is attached to the outer shell 3, separating the solid phase discharge area from the liquid phase discharge area to prevent solid particles from mixing into the liquid phase or liquid phase splashing and polluting the environment. One end of the spiral guide frame 11 is fixed on the outer wall of the inner shell 5, and the other end of the spiral guide frame 11... The end is rotatably connected to the outer shell 3. The lower support 1 serves as the core load-bearing base of the device, supporting the weight of all components such as the support base 2, the enclosed cover 13, the discharge hopper 15, and the drain port 16. At the same time, it provides a stable installation reference for the rotation of the outer shell 3 and the transmission sleeve 4, ensuring the coaxiality of the inner shell 5 and the outer shell 3. The outer shell 3 serves as the main separation chamber of the device. It is driven to rotate at high speed by the coaxial drive mechanism 9, generating a centrifugal force field. At the same time, under the drive of the coaxial drive mechanism 9, the inner shell 5 and the spiral guide frame 11 have a certain rotational speed difference with the outer shell 3. The solid residues thrown onto the inner wall of the outer shell 3 by the centrifugal force will gradually approach the solid discharge port 12 under the action of the spiral guide frame 11, and finally be discharged from the discharge hopper 15.

[0022] Please see Figures 2-5The coaxial drive mechanism 9 includes a first roller 91 fixed to the outer shell 3, a first motor 92 fixedly mounted on the top of the lower support 1, a second roller 93 fixedly connected to the output end of the first motor 92, and a first transmission belt 94 tensioned on the first roller 91 and the second roller 93. During the high-speed rotation of the second roller 93 driven by the first motor 92, the first roller 91 and the outer shell 3 can be driven to rotate synchronously. A third roller 95 is fixedly sleeved on one end of the transmission sleeve 4, and a second motor 95 is fixedly mounted on the bottom of the lower support 1. 7. The output end of the second motor 97 is fixedly connected to the fourth roller 96. The fourth roller 96 and the third roller 95 are tensioned with a second transmission belt 98. During the process of the second motor 97 driving the fourth roller 96 to rotate at high speed, the third roller 95, the transmission sleeve 4, the inner shell 5 and the spiral guide frame 11 can be driven to rotate synchronously through the second transmission belt 98. The rotation speed of the third roller 95 and the first roller 91 is different, which can make the spiral guide frame 11 rotate at a low speed relative to the outer shell 3, pushing the solid residue towards the solid discharge port 12.

[0023] Please see Figures 3-7 and Figure 9The flow rate regulating mechanism 6 includes a distribution pipe 61 fixedly mounted on the transmission sleeve 4, with an inner shell 5 sleeved around the distribution pipe 61. The distribution pipe 61 serves as the core channel for distributing and conveying the gas-liquid mixture, receiving natural gas feed from the inner shell 5. A spiral liquid distribution groove 62 is opened on the side wall of the distribution pipe 61 to uniformly guide the gas-liquid mixture into the outer shell 3. After being ejected, the gas-liquid mixture can smoothly integrate into the rotating flow field, reducing flow field impact losses. An outer sleeve 63 is slidably connected to the distribution pipe 61. A plugging component 65, slidably connected to the liquid distribution groove 62, is uniformly arranged on the inner wall of the outer sleeve 63. A magnetic force is provided on the outer sleeve 63. The magnetic adaptation mechanism 64 includes a support sleeve 641 slidably connected to the outer sleeve 63. A permanent magnet 642 is disposed within the support sleeve 641. An electromagnetic coil is embedded in the outer sleeve 63. A limit tube 643 is provided on the outer sleeve 63, slidingly penetrating the support sleeve 641. The support sleeve 641 is fixed to the spiral guide frame 11 by the inner frame 10. The limit tube 643 is used to install the wire connecting the electromagnetic coil. When the electromagnetic coil is energized, the magnetic field generated will produce a magnetic force between it and the permanent magnet 642, thereby maintaining the position of the outer sleeve 63 within the support sleeve 641. Natural gas passes through the transmission sleeve... 4. After entering the distribution pipe 61, pressure is generated in the space between the distribution pipe 61 and the outer sleeve 63. The gas passes through the liquid distribution groove 62 on the distribution pipe 61 and enters the outer shell 3 for liquid-gas phase separation. At the same time, the generated pressure pushes the outer sleeve 63 closer to the permanent magnet 642. When the pressure of the natural gas increases, the pressure between the distribution pipe 61 and the outer sleeve 63 increases, which pushes the outer sleeve 63 outward. While the outer sleeve 63 slides on the distribution pipe 61, the blocking part 65 slides along the liquid distribution groove 62, opening the blocked liquid distribution groove 62. This can cope with the sudden increase in feed flow and avoid the inner shell from being damaged due to insufficient flow. 5. If the pressure is too high, when the natural gas pressure decreases, the magnetic force will push the outer sleeve 63 inward, blocking part of the liquid distribution groove 62 through the plugging part 65. This prevents the excessive flow rate under low pressure conditions from affecting the stability of the centrifugal separation flow field in the outer shell 3, thus ensuring the gas-liquid separation effect. At the same time, the energized electromagnetic coil will continuously generate heat, exchanging heat with the natural gas flowing into the distribution pipe 61, preventing wax precipitation in the natural gas and preventing liquid phase adhesion from clogging the liquid distribution groove 62. During the process of natural gas pressure change, the plugging part 65 will slide in the liquid distribution groove 62, which will clean the liquid distribution groove 62 and further improve the anti-clogging effect.

[0024] Please see Figures 3-5 and Figure 8The liquid dispensing adjustment mechanism 8 includes a closing ring 81 slidably connected to the side wall of the outer casing 3. A connecting groove 82 is evenly provided on the side wall of the outer casing 3. The closing ring 81 fits into the connecting groove 82 to close it. A connecting plate 83 is evenly provided on the inner wall of the closing ring 81. The connecting plate 83 is slidably connected in the connecting groove 82, and one end of the connecting plate 83 is inserted into a groove on the side wall of the sliding tube 84, allowing it to slide synchronously with the sliding tube 84. The sliding tube 84 is slidably connected to the outer casing. The device is housed in body 3 and communicates with outer shell 3 as the gas phase outlet. One end of sliding tube 84 is rotatably connected to limiting tube 643, allowing it to slide together with limiting tube 643 and outer sleeve 63. A transmission frame 85 is rotatably connected to the sealing ring 81, with one end of the transmission frame 85 rotatably connected to the sealing door 86, which is attached to the liquid phase outlet 7. The sealing door 86 is slidably connected to the support rail 87, which is fixed to outer shell 3. When the outer sleeve 63 slides, it drives the fixed connection... The limiting tube 643 moves outward axially synchronously, and the displacement of the limiting tube 643 is transmitted to the sliding tube 84, pushing the sliding tube 84 to slide axially along the outer shell 3. During the process, the connecting plate 83 pulls the closing ring 81 to slide synchronously along the side wall of the outer shell 3. During the movement of the closing ring 81, the transmission frame 85 drives the position of the closing door 86 on the liquid phase outlet 7. After the open area of ​​the liquid distribution groove 62 increases, resulting in an increase in the flow rate, the total amount of gas-liquid mixture entering the outer shell 3 increases. The liquid phase outlet 7 will adaptively close under the movement of the closing door 86, so that the liquid phase thickness adaptability increases. This avoids insufficient flow field transmission due to excessive gas phase ratio, which would prevent water molecules from obtaining sufficient centrifugal force. Conversely, after the open area of ​​the liquid distribution groove 62 decreases, resulting in a decrease in the flow rate, the total amount of gas-liquid mixture entering the outer shell 3 decreases. The liquid phase outlet 7 will adaptively open under the movement of the closing door 86, so that the liquid phase thickness adaptability decreases. This prevents the liquid phase layer from being too thick, which would lead to gas phase flow space, causing cavitation effect and dispersing the liquid phase, thus ensuring the separation effect of the device.

[0025] It should be noted that, in use, the first motor 92 starts, which drives the first roller 91 fixed on the outer shell 3 to rotate through the second roller 93 and the first transmission belt 94, thereby driving the outer shell 3 to rotate at high speed along the support base 2, providing a core centrifugal force field for gas-liquid centrifugal separation. The second motor 97 starts, which drives the third roller 95 fixed on the transmission sleeve 4 to rotate through the fourth roller 96 and the second transmission belt 98, thereby driving the transmission sleeve 4, the inner shell 5 and the spiral guide frame 11 to rotate synchronously. By adjusting the speed of the first motor 92 and the second motor 97, a stable speed difference is formed between the inner shell 5 and the outer shell 3, providing power for the solid phase particle conveying. After the gas-liquid mixture enters the outer shell 3, it undergoes gas-liquid separation under the centrifugal force generated by the high-speed rotation of the outer shell 3. Because the density of the liquid phase is greater than that of the gas phase, it is thrown towards the inner wall of the outer shell 3 by the centrifugal force, forming a stable liquid phase layer. It flows along the wall to the liquid phase outlet 7 area. The gas phase is less affected by the centrifugal force and converges towards the inner shell 5 in the center, and is finally discharged through the sliding tube 84. The solid particles mixed in the gas and liquid phase are thrown towards the inner wall of the outer shell 3 along with the liquid phase. Under the action of the speed difference between the inner shell 5 and the outer shell 3, the spiral guide frame 11 rotates at a low speed relative to the outer shell 3, and uses the thrust of the spiral blades to gradually push the solid particles to the solid discharge port 12 area. The natural gas to be processed enters the inner shell 5 through the cavity of the transmission sleeve 4, and then flows into the distribution pipe 61 of the flow rate regulating mechanism 6. It is discharged from the spiral liquid distribution groove 62 on the side wall of the distribution pipe 61, which evenly guides the gas-liquid mixture along the rotation direction of the outer shell 3 to the inner wall of the outer shell 3. After the gas-liquid mixture is sprayed out, it blends into the rotating flow field. When the feed pressure increases, it will push the outer sleeve 63 to move outward along the axial direction of the distribution pipe 61, causing the plugging part 65 to exit the liquid distribution groove 62. The effective flow area of ​​the groove increases, the flow rate increases, and the pressure in the inner shell 5 is not too high due to insufficient flow rate. When the feed pressure decreases, the permanent magnet in the support sleeve 641 The repulsive force between 642 and the electromagnetic coil embedded in the outer sleeve 63 pushes the outer sleeve 63 to reset inward, and the blocking part 65 blocks part of the slot opening, reducing the throughput and affecting the stability of the centrifugal separation flow field in the outer shell 3; while the heat generated after the electromagnetic coil is energized is transferred to the liquid distribution slot opening 62 area through the outer sleeve 63, and exchanges heat with the flowing natural gas, maintaining the temperature above the wax precipitation temperature and avoiding liquid phase adhesion; at the same time, the reciprocating sliding of the blocking part 65 in the liquid distribution slot opening 62 can directly clean residual impurities and ensure the unobstructed flow of the liquid distribution slot opening 62.

[0026] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
