Description

Technical Field

[0001] The invention belongs to the technical field of three-phase separation, and in particular relates to a gas-liquid and gas-solid separation device used in gas reservoir development. Background Art

[0002] During the production of gas reservoirs, natural gas is often accompanied by impurities such as liquid water and solid particles. These impurities require efficient purification through gas-liquid-solid three-phase separation equipment. The horizontal gas-liquid-solid three-phase separator mainly includes the following core components:

[0003] 1. Inlet pre-processing unit

[0004] Cyclone separator: It achieves preliminary separation through centrifugal force. Large particles of solids and part of the liquid are thrown to the outer wall, so that the solids and part of the liquid are separated from the natural gas.

[0005] 2. Inertial separation zone

[0006] Parallel plates: Utilize hydrophilic or oleophobic surface properties to make droplets and solid particles adhere and coalesce through inertial collision, change the direction of the fluid, enhance inertial effect, and improve solid-liquid separation efficiency.

[0007] 3. Gravity sedimentation area

[0008] Stratified sedimentation chamber: relies on density difference to achieve three-phase stratification (gas floats up, oil phase is in the middle, water phase sinks, and solid phase sinks to the bottom).

[0009] 4. Gas purification unit

[0010] Demister / Wire Mesh Trap: Captures micron-sized droplets remaining in the gas through fiber mesh or corrugated plates.

[0011] 5. Solid phase treatment module

[0012] Sedimentation hopper / sand discharge port: collects deposited solid particles and discharges sand regularly to prevent blockage.

[0013] 6. Dynamic control system

[0014] Liquid level sensor and valve: control the liquid interface height and maintain stable separation conditions.

[0015] During the use of existing gas-liquid-solid three-phase separators, when the flow rate of natural gas decreases due to reduced pressure, the inertial force of the liquid droplets contained in the natural gas weakens, resulting in a lower probability of collision between the droplets and the parallel plates. The separation process of natural gas and its internal droplets is dominated by gravity sedimentation, resulting in a decrease in the separation effect of the liquid droplets in the natural gas.

DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0038] Example 1

[0039] This embodiment discloses a gas-liquid and gas-solid separation device used in gas reservoir development, which improves the existing gas-liquid-solid separation device.

[0040] like Figures 1 to 6As shown, the gas-liquid and gas-solid separation equipment used in the gas reservoir development includes a shell 2, which is set on a base. A pressure sensor for detecting the internal pressure and connected to the remote control terminal network is set in the shell 2. An air inlet pipe 3 is installed on the upper side of the shell 2. The air inlet pipe 3 is connected to an external air supply device, and the external air supply device is connected to the remote control terminal network. The lower side of the shell 2 is connected with a drain pipe for discharging solid impurities and liquid accumulated in the shell 2. Several cyclone separators 4 are set inside the air inlet pipe 3. The cyclone separator 4 is an existing device for separating solid impurities and large-volume liquid from gas contained in natural gas. The upper right part of the shell 2 An exhaust pipe 5 is installed on the side to discharge the dry natural gas in the shell 2. A wire mesh demister 6 is installed on the right side of the shell 2. The wire mesh demister 6 is an existing device for further removing fine droplets contained in the natural gas. The wire mesh demister 6 is fixedly connected to the exhaust pipe 5 and connects the exhaust pipe 5 with the shell 2. A linear array of fixed plates 7 is fixedly connected to the shell 2. The specific number of fixed plates 7 is selected by the staff. 6 are shown as an example in the figure, and a gap is provided between the lower side of the fixed plate 7 and the inner wall of the shell 2 for allowing liquid and solid to pass through. By controlling the discharge speed of the discharge pipe on the shell 2, the height of the liquid level in the shell 2 is located at the fixed plate 7, the front and rear sides of the fixed plate 7 are provided with guide grooves, the upper side of the fixed plate 7 is fixedly connected to a fixed shell 8, the diameter of the circle where the fixed shell 8 is located is the same as the inner diameter of the outer shell 2, and the fixed shell 8 is provided with two drainage ports symmetrically distributed front and back. The two drainage ports on the fixed shell 8 are respectively connected to the adjacent guide grooves on the adjacent fixed plates 7, so that the liquid condensed in the fixed shell 8 flows along the two drainage ports on the fixed shell 8 and the adjacent guide grooves on the adjacent fixed plates 7 into the outer shell 2, guiding the liquid in the fixed shell 8 to reduce the residual amount of liquid in the fixed shell 8. A plurality of first through grooves are provided on the right side of the fixed shell 8, and the specific number of the first through grooves is determined by the staff. The body is selected without making detailed restrictions. A movable plate 9 is slidably connected in the fixed shell 8. The fixed shell 8 and the movable plate 9 jointly separate the upper half of the outer shell 2. There is a gap between the fixed shell 8 and the adjacent movable plate 9. The movable plate 9 is provided with a plurality of second through grooves. The number of the second through grooves and the first through grooves is not necessarily the same. A plurality of condensation balls 10 are provided between the fixed shell 8 and the adjacent movable plate 9. The diameter of the condensation ball 10 is larger than the width of the second through groove and the first through groove. The condensation ball 10 is in contact with the adjacent movable plate 9 and the fixed shell 8. A driving component is provided in the outer shell 2. The driving component is used to control all the movable plates 9 to move to the right when the pressure in the outer shell 2 drops.

[0041] like Figure 4As shown, the condensation balls 10 are made of elastic deformable material, so that the movable plate 9 can squeeze the adjacent condensation balls 10 during the process of moving to the right, thereby increasing the projected area of ​​the condensation balls 10 on the movable plate 9, and the surface of the condensation balls 10 is coated with a coating made of hydrophobic material to accelerate the condensation speed of the liquid contained in the natural gas.

[0042] like Figure 3 As shown, the left side of the movable plate 9 is provided with a wave surface for increasing the contact area with the natural gas.

[0043] like Figure 6 As shown, a plurality of first through grooves on the fixed shell 8 and a plurality of second through grooves on the adjacent movable plate 9 are staggeredly distributed to increase the contact area with the natural gas.

[0044] like Figures 2 to 5 As shown, the driving assembly includes a moving rod 11, a mounting shell 111 and a driving member 12. The moving rod 11 is sealed and slidably connected to the outer shell 2. The moving rod 11 passes through all the fixed shells 8 and is slidably connected thereto. All the moving plates 9 are fixedly connected to the moving rod 11, and the moving rod 11 drives all the moving plates 9 to move synchronously. The mounting shell 111 is fixedly connected to the outer shell 2. The driving member 12 is fixedly connected to the mounting shell 111. The telescopic end of the driving member 12 is fixedly connected to the moving rod 11. The driving member 12 is an existing device. In the figure, a hydraulic push rod is used as an example to show it. The staff can freely choose it in actual use. The driving member 12 is connected to the remote control terminal network.

[0045] Preparation: Connect the air inlet pipe 3 to the external air supply device, connect the drain port on the lower side of the shell 2 to the sewage treatment pipe, and connect the exhaust pipe 5 to the external air collecting pipe.

[0046] Usage process: The remote control terminal controls the external gas supply device to transport the pretreated natural gas into the air inlet pipe 3 and enter all the cyclone separators 4. After separation by the cyclone separators 4, the large volume of liquid and solid impurities in the natural gas are separated from the natural gas, and the large volume of liquid and solid impurities fall downward into the outer shell 2. The natural gas containing a small volume of liquid flows back from the cyclone separator 4 to the air inlet pipe 3, and then enters the outer shell 2 and flows to the right in the outer shell 2. At the same time, the liquid and solid impurities entering the outer shell 2 move to the right along the bottom of the outer shell 2 through the gap between the outer shell 2 and the fixed plate 7.

[0047] As the natural gas flows rightward within the housing 2, some of the liquid droplets therein naturally fall into the housing 2 due to their own gravity, and some of the liquid droplets move rightward along with the natural gas. The natural gas moving rightward first contacts the left movable plate 9, causing the liquid droplets contained in the natural gas to collide with the movable plate 9 due to inertia and condense on the movable plate 9 to form larger droplets. At the same time, the liquid droplets contained in the natural gas also collide with each other and condense into larger liquids. The condensed droplets flow downward along the movable plate 9 into the housing 2, thereby increasing the dryness of the natural gas. The natural gas then flows along the second through groove on the left movable plate 9 into the left fixed housing 8 and collides with the condensation balls 10 therein, increasing the contact area with the natural gas droplets. As a result, the condensation balls 10 intercept some of the water droplets contained in the natural gas, further increasing the dryness of the natural gas. These water droplets condense on the condensation balls 10 and fall into the left fixed housing 8, and then flow into the housing 2 through the drainage ports on the front and rear sides of the fixed housing 8.

[0048] After the natural gas passes through the fixed shell 8 on the left, the movable plate 9 on the left, and the condensation balls 10 in the fixed shell 8 on the left, it continues to move to the right and contacts the remaining fixed shells 8, the remaining movable plates 9, and the remaining condensation balls 10 in sequence (the specific process is not described in detail again), so that the dryness of the natural gas is gradually improved from left to right. After the natural gas passes through all the fixed shells 8 and all the movable plates 9, the natural gas flows into the exhaust pipe 5, and the wire mesh demister 6 further removes water droplets in the natural gas to ensure the dryness of the natural gas. At the same time, the staff regularly discharges the liquid and solid impurities in the shell 2 through the drain port on the lower side of the shell 2 to prevent the liquid level in the shell 2 from being too high and affecting the normal processing of the natural gas.

[0049] During the process of natural gas flowing in the shell 2, when the pressure detector in the shell 2 detects that the pressure therein drops, the remote control terminal starts the driving member 12, and the driving member 12 drives the moving rod 11 to move to the right, and the moving rod 11 drives all the moving plates 9 to move to the right synchronously, so that the moving plates 9 squeeze all the condensation balls 10 in the adjacent fixed shells 8 during the process of moving to the right, so that the condensation balls 10 are deformed by the pressure, thereby increasing the area of ​​the projection of the condensation balls 10 on the moving plate 9, and at the same time, the deformed condensation balls 10 squeeze the adjacent first through grooves on the adjacent fixed shells 8 and the adjacent moving plates 9. The second through slots adjacent to the plate 9 are blocked to reduce the flow area of ​​the first through slots on the fixed shell 8 and the second through slots on the adjacent movable plate 9, thereby increasing the resistance of the natural gas in the process of passing through the fixed shell 8 and the movable plate 9, and at the same time reducing the volume of the natural gas that can pass through the fixed shell 8 and the movable plate 9 per unit time, increasing the flow speed of the natural gas after passing through the fixed shell 8 and the movable plate 9, thereby maintaining the stability of the inertial force of the liquid droplets contained in the natural gas, allowing the liquid droplets in the natural gas to maintain a stable condensation speed, increasing the probability of collision between the liquid droplets in the natural gas and the movable plate 9, and accelerating the condensation speed of the liquid droplets in the natural gas.

[0050] After the pressure of the gas supplied into the outer shell 2 by the external gas supply device is restored, the remote control terminal controls the driving member 12 to drive the moving rod 11 to reset to the left, so that all the movable plates 9 are reset to the left, so that the natural gas supplied to the outer shell 2 can pass through all the fixed shells 8 and all the movable plates 9 normally and move to the right. After the device is used for a specified time (the time can be specifically set by the staff), the staff shuts down the external gas supply device. After the residual natural gas in the outer shell 2 is completely discharged, the staff cleans and maintains the interior of the outer shell 2 and all parts located therein for subsequent use.

[0051] Example 2

[0052] like Figures 3 to 7 As shown, it also includes a plurality of arc guide plates 13, the number of which is consistent with the number of fixed plates 7, the arc guide plates 13 are fixedly connected to the adjacent fixed plates 7, and an arc surface is provided on the upper side of the arc guide plates 13, the fixed shell 8 is fixedly connected to the adjacent arc guide plates 13, and the movable plate 9 is slidably connected to the adjacent arc guide plates 13, and the width of the projection of the arc guide plates 13 on the horizontal plane is greater than the sum of the width of the projection of the adjacent fixed shell 8 on the horizontal plane and the width of the projection of the adjacent movable plate 9 on the horizontal plane. When the movable plate 9 is not moved, the left side of the arc guide plate 13 is located to the left of the left side of the adjacent movable plate 9, and the right side of the arc guide plate 13 is located to the right of the adjacent fixed shell 8, ensuring that the droplets condensed on the fixed shell 8 and the adjacent movable plate 9 can accurately fall on the adjacent arc guide plates 13.

[0053] In the process of separating the liquid droplets contained in the natural gas, the water droplets condensed on the left side of the movable plate 9, on the condensation balls 10 in the fixed shell 8, on the right side of the fixed shell 8, and inside the fixed shell 8 all fall on the adjacent arc-shaped guide plate 13 and are guided by the upper arc-shaped surface of the arc-shaped guide plate 13 to flow toward the inner wall of the outer shell 2, thereby reducing the probability of these water droplets contacting the natural gas, thereby reducing the probability of the condensed water droplets being blown by the natural gas and being dispersed again and re-entering the natural gas, thereby ensuring the dryness of the natural gas.

[0054] Example 3

[0055] like Figures 2 to 5 and Figure 7 As shown, it also includes a drive motor 14, a threaded rod 141 and a plurality of disturbance members 16. The drive motor 14 is fixedly connected to the housing 2. The drive motor 14 is connected to the remote control terminal network. The remote control terminal controls the output shaft of the drive motor 14 to rotate back and forth. A mounting bracket is provided in the housing 2. The threaded rod 141 is rotatably connected to the mounting bracket of the housing 2. The threaded rod 141 is located below the moving rod 11. The threaded rod 141 passes through the lower side of the housing 2 and is fixed to the output shaft of the drive motor 14. The number of the disturbance members 16 is the same as the number of the arc-shaped guide plates 13. The disturbance members 16 are provided on adjacent arc-shaped guide plates 13. The front and rear sides of the disturbance members 16 are fixed to the adjacent arc-shaped guide plates 13. The disturbance members 16 are normally In this state, the projection on the adjacent movable plate 9 and the projection of the arc guide plate 13 on the adjacent movable plate 9 are located on the same circle. The disturbing member 16 is used to disturb the condensation ball 10 in the adjacent fixed shell 8, so that the condensation ball 10 changes from static to dynamic. The gap between the fixed shell 8 and the adjacent movable plate 9 is not filled with the condensation ball 10. All the disturbing members 16 are commonly fixed with a connecting rod 15. The connecting rod 15 is slidingly connected to all the fixed plates 7. The connecting rod 15 slides in the adjacent first through groove on the adjacent fixed shell 8. The connecting rod 15 slides in the adjacent second through groove on the adjacent movable plate 9. The connecting rod 15 is threadedly connected to the threaded rod 141, and the threaded rod 141 drives all the disturbing members 16 to move synchronously through the connecting rod 15.

[0056] like Figure 7 As shown, the projection of the disturbing member 16 on the horizontal plane is located within the projection of the adjacent fixed shell 8 on the horizontal plane, and the width of the disturbing member 16 is not greater than the diameter of the condensation ball 10, so that the disturbing member 16 can accurately disturb the condensation ball 10 in the adjacent fixed shell 8 during the movement.

[0057] like Figure 7 As shown, the disturbance member 16 is made of elastic deformable material. In the initial state, the disturbance member 16 is located on the right side of the adjacent movable plate 9. The connecting rod 15 stretches and deforms the disturbance member 16 in the process of driving the disturbance member 16 to move upward.

[0058] In the process of using the device to purify natural gas, the remote control terminal repeatedly starts the drive motor 14, and the drive motor 14 drives the threaded rod 141 to rotate. The threaded rod 141 drives the connecting rod 15 to move upward during the rotation process. The connecting rod 15 drives the middle part of all the disturbance members 16 to move upward synchronously during the upward movement, thereby stretching the middle part of all the disturbance members 16 upward. At the same time, the disturbance members 16 squeeze the condensation balls 10 in the adjacent fixed shells 8 during the stretching process, so that the condensation balls 10 move. After the connecting rod 15 moves upward to the limit position, , all the disturbance members 16 are stretched to the limit state, and then the remote control terminal controls the drive motor 14 to drive the threaded rod 141 to rotate in the opposite direction, so that the connecting rod 15 moves downward, so that all the condensation balls 10 move downward by their own gravity, so that all the condensation balls 10 in the fixed shell 8 move synchronously with the contraction of the adjacent disturbance members 16, thereby shaking off the condensed water droplets on the condensation balls 10, accelerating the falling speed of the water droplets on the condensation balls 10, and reducing the impact of the condensed water droplets on the condensation balls 10 on the subsequent natural gas dryness and humidity when they come into contact with the subsequent flowing natural gas.

[0059] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed in the present application based on the technical solution and its improved ideas, which should be covered by the scope of protection of the present application.
