Description

Technical Field

[0001] This application relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separation device. Background Technology

[0002] In industrial fields such as crude oil extraction, natural gas gathering and transportation, and multiphase flow metering, the separation of gas-liquid mixtures (such as a three-phase flow of crude oil, water, and natural gas extracted from the wellhead) is a crucial prerequisite for subsequent metering, transportation, and processing processes. The effectiveness of gas-liquid separation directly affects metering accuracy, equipment operational stability, and production efficiency.

[0003] In existing technologies, gas-liquid separation mainly employs methods such as separators or columnar cyclone separation. Traditional separators are typically pressure vessel structures that allow gas and liquid to separate naturally by expanding the flow space. However, they suffer from problems such as large footprint, bulky equipment, and the need for registration and approval for on-site installation, resulting in poor adaptability.

[0004] However, the inventors have discovered at least the following technical problems in the related technologies: most existing separators are pressure vessel structures, and the flow splitting structure often has problems such as uneven medium distribution and insufficient flow rate, resulting in large differences in the load of subsequent separation units and making it difficult to achieve efficient multi-stage separation. Utility Model Content

[0005] One object of this application is to provide a gas-liquid separation device that at least solves the above-mentioned problems.

[0006] To achieve the above objectives, some embodiments of this application provide a gas-liquid separation device, comprising:

[0007] The shunt assembly includes an input pipe and multiple shunt pipes connected to the input pipe;

[0008] The separation component includes at least a first pipe group connected to a plurality of branch pipes, and a second pipe group connected to the first pipe group, wherein both the first pipe group and the second pipe group include a plurality of vertical pipes.

[0009] The diversion pipe is inclined downwards from its inlet end to its outlet end along the direction of fluid flow.

[0010] In some alternative embodiments, the outlet port of the diversion pipe has a flat or elliptical structure to increase the medium flow rate.

[0011] In some alternative embodiments, multiple branch pipes are arranged sequentially along the axial direction of the input pipe and are parallel to each other.

[0012] In some alternative embodiments, the multiple vertical pipes of the separation component are arranged in parallel, and the gas connection ports of two connected vertical pipes are located in the upper region of the pipes.

[0013] In some alternative embodiments, the distances between the multiple vertical pipes of the first pipe group and the input pipe are equal.

[0014] In some alternative embodiments, the second pipe group includes: a direct connection group, wherein the vertical pipe of the direct connection group is directly connected to the vertical pipe of the first pipe group; and an indirect connection group, wherein the vertical pipe of the indirect connection group is indirectly connected to the vertical pipe of the first pipe group via the vertical pipe of the direct connection group.

[0015] In some alternative embodiments, the system further includes: a liquid conduit connected to the bottom of the vertical conduit of the separation component to discharge the separated liquid; and a gas conduit connected to the top of the vertical conduit of the separation component to discharge the separated gas.

[0016] In some alternative embodiments, a mist eliminator is also included, located in the upper region of the vertical conduit of the separation assembly, to remove droplets carried in the gas.

[0017] In some alternative embodiments, a magnetic level gauge is also included, disposed on one side of the vertical pipe and arranged parallel to the vertical pipe, to display the liquid level in the vertical pipe of the separation component.

[0018] In some alternative embodiments, it further includes: a flange level gauge, disposed on a vertical pipe in the separation assembly away from the input pipe, for measuring and transmitting a level signal to trigger the opening and closing of valves on the liquid pipe and / or gas pipe.

[0019] Compared with related technologies, the solution provided in this application disperses the mixed medium into multiple diversion pipes through a diversion component, thereby achieving initial diversion of the medium.

Multiple sets of vertical pipes form a multi-stage separation path, extending the gas-liquid separation time and enhancing the separation effect. Attached Figure Description

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0035] Combination Figures 1 to 4 As shown in the figure, an embodiment of this disclosure provides a gas-liquid separation device, including a flow-diverting component and a separation component. The flow-diverting component includes an input pipe 10 and a plurality of flow-diverting pipes 20 connected to the input pipe 10; the separation component includes at least a first pipe group 30 corresponding to and connected to the plurality of flow-diverting pipes 20, and a second pipe group 40 connected to the first pipe group 30, both the first pipe group 30 and the second pipe group 40 including a plurality of vertical pipes a; wherein, the flow-diverting pipes 20 are arranged downwardly along the fluid flow direction from their inlet end to their outlet end.

[0036] The gas-liquid separation device provided in this embodiment disperses the mixed medium into multiple diversion pipes 20 through a diversion component, achieving initial diversion of the medium. The diversion pipes 20 are inclined downwards to utilize gravity to assist the flow of the medium, reducing flow resistance. At the same time, they create a stable pre-flow state for subsequent swirling separation in the vertical pipe a, improving the gas-liquid separation efficiency of the separation component. Multiple sets of vertical pipes a form a multi-stage separation path, extending the gas-liquid separation time and enhancing the separation effect.

[0037] Optionally, the outlet port of the diversion pipe 20 has a flat or elliptical structure to increase the medium flow rate.

[0038] A flat or elliptical outlet structure can reduce the flow cross-section and increase the medium velocity according to the principles of fluid mechanics, allowing the medium to enter the vertical pipe a at a higher speed, enhancing the swirling intensity, promoting the centrifugal separation effect caused by the density difference between the gas and liquid phases, and improving the separation efficiency.

[0039] Optionally, multiple branch pipes 20 are arranged sequentially along the axial direction of the input pipe 10 and are set in parallel.

[0040] The parallel and axially arranged diversion pipes 20 can evenly distribute the medium to each pipe after diversion, avoiding the problem of excessive local separation load caused by medium flow deviation, ensuring the stability and consistency of the output medium of each diversion pipe 20, and providing a basis for the uniform separation of subsequent separation components.

[0041] Optionally, the multiple vertical pipes a of the separation component are arranged in parallel, and the gas inlet of two connected vertical pipes a is located in the upper region of the pipe. The liquid inlet of the two connected vertical pipes a is located at the bottom of the pipe and is connected to the manifold 501 of the liquid pipe 50.

[0042] The parallel arrangement of vertical pipes facilitates the overall structural layout and installation of the device; the gas connection port is located in the upper area, which allows the gas that has undergone preliminary separation to preferentially enter the next stage pipeline for further separation, reducing the interference of liquid on gas flow, and at the same time preventing incompletely separated liquid from directly entering the next stage, thereby improving the continuity and effectiveness of multi-stage separation.

[0043] Optionally, the multiple vertical pipes a of the separation component are evenly spaced.

[0044] Equal spacing ensures uniform flow field distribution among vertical pipes a, avoids mutual interference between airflow and liquid flow caused by spacing differences, ensures consistent separation environment for each vertical pipe a, and improves the stability of overall separation effect.

[0045] Optionally, the distances between the multiple vertical pipes a of the first pipe group 30 and the input pipe 10 are equal.

[0046] The equal spacing design ensures that the medium after the input pipe 10 is split reaches each vertical pipe a in the first pipe group 30 along the same path, reducing the problem of uneven energy loss of the medium due to distance differences, ensuring that the initial separation conditions of each vertical pipe a are the same, and improving the separation uniformity.

[0047] Optionally, the second pipe group 40 includes: a direct connection group 401, in which the vertical pipe a of the direct connection group 401 is directly connected to the vertical pipe a of the first pipe group 30; and an indirect connection group 402, in which the vertical pipe a of the indirect connection group 402 is indirectly connected to the vertical pipe a of the first pipe group 30 via the vertical pipe a of the direct connection group 401.

[0048] By combining direct and indirect connections, a multi-stage progressive separation path is formed, allowing the medium to undergo multiple separation processes in the separation components, extending the gas-liquid contact separation time and improving the thoroughness of separation; at the same time, the separation load can be flexibly allocated according to the characteristics of the medium to optimize the separation efficiency.

[0049] For example, one diversion pipe 20 can correspond to multiple vertical pipes a, which can increase the separation path and improve the single-separation effect. Multiple diversion pipes 20 can be provided on the input pipe 10, which can increase the separation output.

[0050] Optionally, it also includes: a liquid conduit 50 connected to the bottom of the vertical conduit a of the separation component to discharge the separated liquid; and a gas conduit 60 connected to the top of the vertical conduit a of the separation component to discharge the separated gas.

[0051] Liquid pipeline 50 discharges the separated liquid from the bottom, and gas pipeline 60 discharges the separated gas from the top, achieving effective diversion and output of gas-liquid separation, avoiding secondary mixing of gas and liquid, ensuring the purity of the separated medium, and providing a reliable medium source for subsequent metering and other processes.

[0052] Optionally, the liquid conduit 50 collects the liquid in all the vertical conduits a of the separation assembly and then discharges it through the outlet section 502 of the liquid conduit 50.

[0053] The centralized liquid discharge design reduces the number of pipe interfaces and simplifies the device structure; at the same time, centralized discharge can stabilize the liquid output pressure and flow rate, facilitating the subsequent unified metering and treatment of the separated liquid.

[0054] Optionally, the outlet section 502 of the liquid pipe 50 is away from the input pipe 10 and is located outside the vertical pipe a that is furthest from the input pipe 10 in the indirect connection group 402.

[0055] The outlet section 502 is far from the input pipe 10 to avoid the flow of the input medium interfering with the liquid discharge; it is set outside the farthest vertical pipe a so that the liquid can undergo complete multi-stage separation in the separation component before being discharged, further reducing the possibility of gas entrainment in the liquid and improving the liquid separation effect.

[0056] Optionally, the gas conduit 60 collects all the gas in the vertical conduits a of the separation assembly and then discharges it through the outlet end of the gas conduit 60.

[0057] Centralized gas collection can integrate dispersed gas flows, stabilize gas output parameters (such as pressure and flow rate), reduce gas flow losses, and facilitate subsequent unified metering and purification of the gas.

[0058] Optionally, the gas moves sequentially from the vertical pipe a directly connected to the branch pipe 20 to the vertical pipe a further away from the branch pipe 20, and then converges and is discharged into the gas pipe 60.

[0059] Optionally, the outlet end of the gas pipe 60 is away from the input pipe 10 and is located on the vertical pipe a that is furthest from the input pipe 10 in the indirect connection group 402.

[0060] The outlet end being away from the input pipe 10 can avoid interference from the input medium on the gas discharge; it is set on the farthest vertical pipe a, so that the gas undergoes sufficient multi-stage separation and purification in the separation component before being discharged, reducing the probability of liquid droplets being entrained in the gas and improving the gas separation purity.

[0061] Optionally, it also includes a mist eliminator located in the upper region of the vertical conduit a of the separation assembly to remove droplets carried in the gas.

[0062] The mist eliminator can effectively capture tiny liquid droplets carried in the gas, further purify the gas, reduce the amount of liquid entrained in the gas, improve the gas separation quality, and meet the requirements of subsequent high-precision metering or processes for gas purity.

[0063] For example, the mist eliminator at the top of the vertical pipe a ensures that the diameter of the liquid droplets carried in the gas is no greater than 10 μm, thereby keeping the droplet size in the gas within a small range, significantly reducing the amount of liquid carried in the gas, meeting the stringent requirements for gas quality in subsequent high-precision metering, and improving metering accuracy.

[0064] Optionally, it also includes: a magnetic level gauge 70, which is disposed on one side of the vertical pipe a and is arranged parallel to the vertical pipe a to display the liquid level in the vertical pipe a of the separation component.

[0065] The magnetic float level gauge 70 is set parallel to the vertical pipe a, which can intuitively and accurately display the liquid level height in the pipe, making it convenient for operators to monitor the operating status of the separation component in real time and detect abnormal liquid level problems in a timely manner.

[0066] Optionally, it also includes: a flange level gauge 80, located on a vertical pipe a opposite to the input pipe 10 in the separation assembly, for measuring and transmitting a level signal to trigger the opening and closing of valves on the liquid pipe 50 and / or the gas pipe 60.

[0067] The flange level gauge 80 can accurately measure the liquid level and transmit signals to realize automated monitoring of the liquid level; by triggering the opening and closing of the valve, it can automatically adjust the discharge of liquid and gas, maintain the stability of the liquid level in the separation component, ensure the continuous and reliable operation of the separation process, and improve the automation control level of the device.

[0068] Optionally, the vertical pipes a in the separation component are arranged in a matrix.

[0069] The matrix arrangement allows for the placement of more vertical pipes within a limited space, improving the device's separation and processing capacity. At the same time, the matrix structure facilitates the connection between pipes and the flow of media, optimizes the flow field distribution, and enhances the overall separation efficiency.

[0070] Optionally, the collecting section of the liquid pipeline 50 is equipped with a drain outlet. The drain outlet can periodically discharge impurities, silt, etc. accumulated in the device, preventing impurities from clogging the pipeline and affecting the separation effect. It also facilitates device maintenance and cleaning, and extends the service life of the device.

[0071] In practical production scenarios such as crude oil extraction and multiphase flow metering, gas-liquid mixtures (including crude oil, water, natural gas, etc.) need to be efficiently separated into gas and liquid phases through gas-liquid separation devices to provide a pure medium for subsequent metering, transportation, and other processes. For example, the separation process is described using a setup of three branch pipes 20 and four vertical pipes a corresponding to each branch pipe 20.

[0072] Media input and initial diversion stage

[0073] The gas-liquid mixture at the production site (such as a three-phase flow of oil, water, and gas extracted from the wellhead) first enters the input pipeline 10 of the unit through the main delivery pipeline. At this time, the medium is in a gas-liquid unseparated state, containing a large number of bubbles, droplets, and continuous liquid phases, and needs to be initially dispersed by the flow divider assembly.

[0074] The mixed medium in the input pipe 10 flows into the diversion assembly, where it is diverted through three diversion pipes 20 arranged in parallel along the axial direction of the input pipe 10. Since the diversion pipes 20 are inclined downwards from the inlet end to the outlet end along the fluid flow direction, they assist the medium flow with the help of gravity, reduce flow resistance, and at the same time enable the medium to form a stable pre-flow state.

[0075] The outlet end of each diversion pipe 20 adopts a flat or elliptical structure, which reduces the flow cross-section and increases the medium velocity according to the principles of fluid mechanics. The high-speed medium enters the vertical pipe a of the subsequent separation component at a downward angle, laying the foundation for vortex separation.

[0076] Primary separation: Initial gas-liquid separation in the first pipeline group 30

[0077] Three branch pipes 20 correspond sequentially to three vertical pipes a, and all vertical pipes a are equally spaced and parallel to the input pipe 10 to ensure uniform energy distribution of the medium received by each pipe. After the high-speed medium enters the vertical pipe a from the flat outlet, the medium forms a swirling motion along the inner wall of the pipe due to the vertical shape of the pipe, generating a centrifugal force much greater than gravity.

[0078] Under centrifugal force, the denser liquid phase (crude oil, water) is thrown towards the inner wall of the pipe and flows downward along the pipe wall; the less dense gas phase (natural gas) gathers towards the center of the pipe and moves upward. At this time, the vertical pipe a of the first pipe group 30 completes the initial gas-liquid separation, with the liquid initially gathering at the bottom of the pipe and the gas initially gathering at the top of the pipe.

[0079] Each vertical pipe a has a mist eliminator in the upper part, which can capture larger droplets (diameter > 10 μm) carried in the gas. The droplets fall back to the bottom of the pipe under the action of gravity, reducing the amount of liquid carried in the gas.

[0080] Secondary separation: Deep separation of the second pipeline group 40

[0081] The three vertical pipes a of the first pipe group 30 are connected to the second pipe group 40 through a gas inlet in the upper region (the inlet is located at the top of the pipe to avoid liquid interference with gas flow). The second pipe group 40 adopts a "direct connection group 401 + indirect connection group 402" structure: the vertical pipe a of the direct connection group 401 is directly connected to the first pipe group 30 and receives the gas-liquid mixture after primary separation; the vertical pipe a of the indirect connection group 402 indirectly receives the medium through the vertical pipe a of the direct connection group 401, forming a multi-stage progressive separation path.

[0082] The medium entering the second pipe group 40 undergoes swirling motion again. The incompletely separated liquid phase continues to settle downwards along the pipe wall, while the gas flows upwards and is purified again by the mist eliminator, further reducing the residual liquid droplets in the gas (the final droplets are no larger than 10μm). At this time, the vertical pipes a of the second pipe group 40 are arranged in a matrix, and the equally spaced structure ensures a uniform flow field and avoids mutual interference between the media.

[0083] Since the bottoms of all vertical pipes are connected by a connecting structure, the liquid naturally reaches equilibrium under the action of gravity, and the liquid level in each pipe remains consistent, providing stable conditions for subsequent separation and output.

[0084] Output and monitoring of separated media

[0085] The separated liquids collect at the bottom of all vertical pipes a and are discharged through liquid pipe 50. After collecting the liquids from all vertical pipes a, the outlet section 502 of liquid pipe 50 is away from the input pipe 10 and is located outside the vertical pipe a furthest from the input pipe 10 in the indirect connection group 402 (away from input interference, ensuring that the liquid is discharged after sufficient separation), and finally flows to the liquid metering instrument.

[0086] The separated gas gathers at the top of all vertical pipes a and is discharged through gas pipe 60. The outlet end of gas pipe 60 is away from the input pipe 10 and is located at the top of the farthest vertical pipe a in the indirect connection group 402. The deeply purified gas flows to the gas metering instrument.

[0087] A magnetic level gauge 70 is installed parallel to one side of the vertical pipe a to display the liquid level in the pipe in real time, which is convenient for operators to monitor intuitively.

[0088] A flange level gauge 80 is installed on the vertical pipe a, which is away from the input pipe 10, to measure the liquid level and transmit the signal to the PLC system. When the liquid level exceeds the preset value, the PLC triggers the valve of the liquid pipe 50 to open and drain the liquid; when the liquid level is too low, it triggers the valve of the gas pipe 60 to adjust the exhaust volume and maintain stable operation of the device.

[0089] This embodiment achieves efficient separation of gas and liquid media through a process of "diversion - primary cyclone separation - secondary progressive separation - purification output". It utilizes technologies such as inclined diversion pipe 20, multi-stage vertical pipe a, mist eliminator and automated liquid level control. The separated liquid has low gas content and low gas-liquid content, which can meet the high precision requirements of subsequent metering and transportation processes. Moreover, the device has a simple structure and is easy to maintain, making it suitable for industrial scenarios such as crude oil metering.
