Description

Technical Field

[0001] The invention relates to the field of multiphase flow meters, and in particular to a high-precision gas-liquid multiphase flow meter. Background Art

[0002] Gas-liquid multiphase flowmeter is mainly used to measure the flow of complex fluids composed of gas and liquid. It is widely used in the fields of petroleum, chemical industry, natural gas extraction and processing.

[0003] In the related technical means, after the gas-liquid multiphase flow enters the flow meter, the gas-liquid mixture is separated by the gas-liquid cyclone separator, and then the separated gas and liquid phases are measured by the gas flow meter and the mass flow meter respectively. At the same time, the water content in the liquid can also be measured by equipment such as a water content analyzer, so as to further calculate the mass of the oil and water phases.

[0004] However, when the gas-liquid cyclone separator in the multiphase flow meter in the prior art separates gas and liquid, the liquid is thrown to the outer wall of the separator under the action of centrifugal force, flows downward along the wall, and is finally discharged through a specific outlet, while the gas gathers in the central area of ​​the cyclone, and due to the lack of effective driving force, can only move slowly upward through natural convection and diffusion until it is discharged from the gas outlet. This separation and discharge mechanism not only affects the separation efficiency, but may also cause the gas to carry some tiny droplets, further affecting the measurement accuracy.

[0048] Further, such as Figure 2 , Fig.15As shown, in order to realize the overall lifting of the lifting shaft 8, the driving cylinder 9, and the booster blade 12, a driving mechanism for driving the longitudinal displacement of the lifting shaft 8 is provided at the upper end of the gas-liquid cyclone separator 1, and the driving mechanism includes a slider 38 slidably arranged on the inner side of one end of the second fixed frame 13, and a pulling rod 39 is movably connected to the bottom of the slider 38, and the lower end of the pulling rod 39 is movably connected to the side of the lifting shaft 8, and a traction rod 37 extending to the outside of the gas-liquid cyclone separator 1 is provided on one side of the slider 38, and the traction rod 37 is movably connected to the gas-liquid cyclone separator 1.

[0049] like Figure 7-Figure 12As shown, in order to increase the stability of the end block 17 and the first rack 18 and ensure that the first rack 18 can be fully meshed with the first gear 32, a locking mechanism for locking the end block 17 is provided on the inner side of the groove 16. The locking mechanism includes mounting grooves 20 provided at the upper and lower ends of the inner side of the groove 16. A movable block 22 is movably connected to the inner side of the mounting groove 20 along the radial direction of the polygonal column 15.

A spring 21 extending to the groove 16 is provided on the outer side of the movable block 22. The force block 19 of the inner cavity, and the first elastic member 21 of the force block is preferably a spring, and both the upper and lower ends of 19 are inclined surfaces. The side wall of the movable block 22 located near the center of the gas-liquid cyclone separator 1 is fixedly provided with a first clamping block 23 extending to the inner cavity of the groove 16, and the first clamping block 23 is located at the end of the force block 19 away from the center of the gas-liquid cyclone separator 1, and the first clamping block 23 corresponds to the force block 19, and the end of the first clamping block 23 away from the center of the gas-liquid cyclone separator 1 is an inclined surface, and the first rack 18 is located at the end of the gas-liquid cyclone separator 1 away from the center The inner side of the end block 17 is provided with a first card slot 25 corresponding to the first card block 23, and the first card block 23 is engaged with the first card slot 25.

The inner side of the end block 17 located at one end of the first rack 18 close to the center of the gas-liquid cyclone separator 1 is provided with a second card block 48 extending to the inner side of the groove 16. There is a second card slot 26 corresponding to the second card block 48, and the second card block 48 is engaged with the second card slot 26. When unlocking, a pin 34 for pushing the force block 19 to move is provided on one end of the fixed shaft 31 extending to the inner side of the groove 16, and is configured so that when one end of the push plate 33 contacts the end block 17 close to the center of the gas-liquid cyclone separator 1, the second card block 48 can be separated from the second card slot 26, and when the other end of the push plate 33 contacts the end block 17 far from the center of the gas-liquid cyclone separator 1, the first card block 23 can be separated from the first card slot 25.

[0050] like Fig.12 As shown, in order to prevent the second clamping block 48 and the first clamping block 23 from blocking the end block 17, a first avoidance opening 24 corresponding to the first clamping block 23 is provided on the inner side of the end block 17 located at one end of the first rack 18 close to the center of the gas-liquid cyclone separator 1, and a second avoidance opening 27 corresponding to the second clamping block 48 is provided on the inner side of the end block 17 located at one end of the first rack 18 away from the center of the gas-liquid cyclone separator 1.

[0051] like Fig.13As shown, in order to increase the stability of the end block 17 and the inner wall of the groove 16, a reinforcement component is provided on the side wall of the end block 17, and the reinforcement component includes a blind hole 28 provided on the side wall of the end block 17, and the blind hole 28 is movably connected with an abutment block 30 for abutting and cooperating with the inner wall of the groove 16, and a second elastic member 29 is provided between the inner end of the abutment block 30 and the inner wall of the blind hole 28, and the second elastic member 29 is preferably a spring.

[0052] In addition, if Figure 2 , Figure 16-Figure 17 As shown, it also includes a flow control mechanism, which includes a floating block 7 that is vertically movably arranged on the inner side of the gas-liquid cyclone separator 1 and can float on the top of the liquid entering the gas-liquid cyclone separator 1. The floating block 7 is annular, and there is a gap between the side of the floating block 7 and the inner wall of the gas-liquid cyclone separator 1, which can reduce the vortex that affects the rotation of the liquid. The lifting shaft 8 is located in the middle of the floating block 7. The side of the gas-liquid cyclone separator 1 close to the inlet 6 is movably connected to the radial direction of the gas-liquid cyclone separator 1 with a sliding frame 42. The inner end of the sliding frame 42 is provided with a floating block 7, and the bottom of the driving block 14 is an inclined surface, the outer end of the sliding frame 42 is provided with a second rack 41, a third elastic member 43 is provided between the driving block 14 and the inner wall of the gas-liquid cyclone separator 1, and the upper and lower ends of the inner side of the inlet 6 are rotatably provided with a rotating shaft 45, a sealing ball 44 adapted to the inner diameter of the inlet 6 is fixedly provided on the rotating shaft 45, and a through hole for the gas-liquid mixture to pass through is provided on one side of the sealing ball 44, and a second gear 46 meshing with the second rack 41 is fixedly provided at the lower end of the rotating shaft 45 located at the bottom of the sealing ball 44.

[0053] like Fig.17 As shown, in order to filter out impurity particles in the gas and liquid, a filter screen 47 is obliquely arranged in the through hole on the side of the sealing ball 44. The oblique arrangement not only facilitates the falling of impurity particles, but also increases the contact area with the gas and liquid, while the pressure per unit area is small.

[0054] When in use, the gas-liquid mixture enters through the inlet 6, and the particulate impurities in the gas-liquid mixture can be filtered out by the filter screen 47, and then enters the gas-liquid cyclone separator 1. The gas-liquid mixture forms a rotating vortex in the gas-liquid cyclone separator 1. The rotation speed in the vortex generates centrifugal force. The liquid is thrown to the outer wall of the gas-liquid cyclone separator 1 under the action of the centrifugal force, and flows downward along the wall surface, and is finally discharged through the liquid outlet 3 and measured by the mass flow meter 5, while the gas gathers in the central area of ​​the cyclone, and then rises, and is finally discharged through the gas outlet 2 and measured by the gas flow meter 4;

[0055] During this period, the driving source 10 is controlled to drive the rotating disk 35 to rotate. The rotating disk 35 can drive the traction rod 37 and the slider 38 to move back and forth as a whole through the cooperation of the pin shaft 36 and the through groove 40, and then the slider 38 drives the lifting shaft 8 to move back and forth through the pulling rod 39, and the driving cylinder 9 is driven by the lifting shaft 8 to move back and forth on the outside of the polygonal column 15. When the driving cylinder 9 moves in a direction away from the center of the gas-liquid cyclone separator 1, the driving cylinder 9 drives the fixed shaft 31, the booster blade 12, and the first gear 32 to move as a whole. When the first rack 18 is located at one end of the inner side of the groove 16 close to the center of the gas-liquid cyclone separator 1, the first clamping block 23 and the first clamping groove 25 are in a clamping state, so that the first gear 32 can be relatively displaced with the first rack 18, and then the first gear 32 is driven by the lifting shaft 8 to move back and forth on the outside of the polygonal column 15. The fixed shaft 31 drives the boost blade 12 to rotate, and the boost blade 12 gradually rotates from vertical to horizontal, and then the multiple boost blades 12 are closed. When one end of the push plate 33 contacts the end block 17 away from the center of the gas-liquid cyclone separator 1, the ejector pin 34 just pushes the force block 19 into the mounting groove 20, and then the movable block 22 compresses the first elastic member 21 while driving the first clamping block 23 to move inward, and the first clamping block 23 is separated from the first clamping groove 25. The multiple boost blades 12 remain horizontal, the first rack 18 and the first gear 32 are relatively stationary, and then the driving cylinder 9, the first rack 18, the first gear 32, the end block 17, and the push plate 33 are integrally displaced in a direction away from the center of the gas-liquid cyclone separator 1, so that the separated gas or liquid is pushed by the boost blade 12 pushes to increase the flow rate of gas and liquid. When the first rack 18 moves to the limit distance away from the center of the gas-liquid cyclone separator 1, the second block 48 will be stuck in the second slot 26. At this time, the first rack 18 and the end block 17 are locked again, and then the driving cylinder 9 starts to move toward the center of the gas-liquid cyclone separator 1. The first gear 32 is relatively displaced with the first rack 18 again. The first gear 32 drives the booster blade 12 to reverse through the fixed shaft 31. The booster blade 12 gradually flips to vertical, preventing the booster blade 12 from sucking gas or liquid back into the gas-liquid cyclone separator 1 again. When one end of the push plate 33 contacts the end block 17 close to the center of the gas-liquid cyclone separator 1, the first rack 18 and the first gear 32 are in contact with each other. It is relatively still, and the ejector pin 34 just pushes the force-bearing block 19 away from the center of the gas-liquid cyclone separator 1 into the mounting groove 20, and then the movable block 22 compresses the first elastic member 21 while driving the second clamping block 48 to separate from the second clamping groove 26, and then the driving cylinder 9 can drive the first rack 18, the end block 17, and the first gear 32 to move as a whole toward the center of the gas-liquid cyclone separator 1, and then wait to move away from the center of the gas-liquid cyclone separator 1 again. The booster blade 12 flips to a vertical position when it moves toward the center of the gas-liquid cyclone separator 1, and flips to a horizontal position when it moves away from the center of the gas-liquid cyclone separator 1, which can realize the boosted discharge of gas and liquid, improve the discharge efficiency, improve the overall separation efficiency, and has a compact structure and is easy to use;

[0056] It should be noted that the first avoidance opening 24 is used to avoid the first clamping block 23, and the second avoidance opening 27 is used to avoid the second clamping block 48. The end blocks 17 at both ends of the first rack 18 are fixed without interfering with each other, and both are unlocked by pushing the force-bearing block 19 by the ejector pin 34. Moreover, since both ends of the force-bearing block 19 are inclined surfaces, the end block 17 can pass through the force-bearing block 19.

[0057] In addition, when the discharge rate in the inlet 6 is greater than the discharge rate of the liquid outlet 3, the liquid in the lower end of the gas-liquid cyclone separator 1 will gradually rise. In order to prevent the liquid from submerging the inlet 6 or even the gas outlet 2, a float 7 is provided in the gas-liquid cyclone separator 1. When the liquid rises to a certain level, the float 7 moves upward and pushes the drive block 14 to move laterally. The drive block 14 compresses the third elastic member 43 and drives the second rack 41 to move laterally. The second rack 41 drives the sealing ball 44 to rotate through the second gear 46, and then the flow in the inlet 6 is reduced, so that the liquid level in the gas-liquid cyclone separator 1 can be gradually reduced. After the relief, the third elastic member 43 is gradually reset, and the float 7 falls.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
