Description

Technical Field

[0001] The utility model belongs to the technical field of fluid transportation, and in particular relates to a gas-liquid pressurizing and separating device. Background Art

[0002] During the exploitation of oil and gas fields, the main oil and gas products produced in the oil and gas fields include oil, natural gas, water, and sand and gravel mixed in the liquid. Since the mixing ratio of the oil and gas mixture changes constantly during the exploitation process, and contains impurities such as sand and gravel, the mixed pump is greatly impacted and worn during the transportation process, which seriously damages the sealing of various mixed pumps and increases the maintenance workload during the transportation process.

[0003] In the related art, the produced oil and gas mixture is usually transported to a large gas-liquid separator for solid, liquid and gas separation, and then pumps, compressors, air compressors and other driving equipment are used to extract and transport it separately. In this process system, the volume and weight of the gas-liquid separator are large, and the flexibility of use is reduced. At the same time, the additional gas-liquid separator and supporting transportation equipment not only greatly increase the operating cost, but also during the gas-liquid separation process, the gas will carry some liquid molecules into the compressor. After the accumulation of liquid molecules, it is easy to cause liquid hammer and damage to the compressor. At the same time, due to the incompressibility of the liquid, the space occupied by the compressor makes it impossible for the compressor to fully exert its benefits, which leads to a decrease in the efficiency of the compressor. In severe cases, it will cause damage to the compressor. There are technical problems such as high operating costs and high failure rates of transportation equipment. Utility Model Content

[0004] In view of the above-mentioned technical problems, the utility model proposes a gas-liquid pressurization and separation device. The gas-liquid pressurization and separation device uses water as a sealing piston to achieve zero leakage. The gas-liquid mixture is sucked in and discharged by raising and lowering the water level in two reversing booster tanks. The gas-liquid mixture is separated by water to ensure that the gas-liquid mixture will not be sucked into the reversing mechanism, thereby ensuring the reliability of the equipment. At the same time, by providing a pressure-stabilizing separation tank, the gas-liquid mixture discharged by the reversing booster tank after pressurization is stabilized, stored in energy, and separated, thereby reducing the pressure fluctuation of the conveying.

[0005] In order to achieve the above object, the utility model provides a gas-liquid pressurization separation device, which comprises:

[0006] An input mechanism, an input end of which is connected to a gas-liquid low-pressure pipeline;

[0007] Two reversing booster tanks, each having an inlet and an outlet at its top end, the inlet being connected to the output end of the input mechanism so that the input mechanism delivers a gas-liquid mixture to the reversing booster tank;

[0008] A pressure-stabilizing separation tank, the top of which is provided with an inlet and an outlet connected to a gas high-pressure pipeline, the inlet is connected to the two outlets, so that the gas-liquid mixture in the reversing booster tank is pressurized to the pressure-stabilizing separation tank, and the bottom of the pressure-stabilizing separation tank is provided with a liquid outlet connected to a liquid high-pressure pipeline;

[0009] The reversing booster tank has a preset volume of water stored in it, and it and the pressure stabilizing separation tank form a pressure tank;

[0010] A reversing mechanism, connected between the two reversing booster tanks, to drive the water in the two reversing booster tanks to circulate back and forth;

[0011] The gas-liquid mixture transported by the input mechanism to the two reversing booster tanks is located above the water level. When the reversing mechanism drives the water in the two reversing booster tanks to circulate back and forth, the gas-liquid mixture in the gas-liquid low-pressure pipeline is sucked into the reversing booster tank with a low water level through the input mechanism, and the gas-liquid mixture in the other reversing booster tank is pressurized to the pressure-stabilizing separation tank, wherein the gas enters the gas high-pressure pipeline through the gas outlet, and the liquid enters the liquid high-pressure pipeline through the liquid outlet.

[0012] The gas-liquid boosting and separation device provided by the technical solution uses water to drive the gas-liquid mixture in the two reversing boosting tanks to boost the pressure in the pressure-stabilizing separation tank. Water is used as a sealing piston to achieve zero leakage, ensuring that the gas-liquid mixture will not be sucked into the reversing mechanism, thereby ensuring the reliability of the equipment. The boosted gas-liquid mixture stores energy, stabilizes the pressure, and separates during the pressure-stabilizing separation. The gas and liquid enter the gas high-pressure pipeline and the liquid high-pressure pipeline for transportation respectively, thereby saving the subsequent investment in separation equipment and transportation equipment. At the same time, there is no need to use a compressor or pump to separate and extract the gas and liquid separately, thus avoiding the gas carrying some liquid molecules into the compressor and being damaged, thereby improving the transportation efficiency of the gas and liquid.

[0013] In some other embodiments of the present application, the gas-liquid pressurization separation device also includes a first pipeline, one end of which is connected to the gas high-pressure pipeline, and the other end of which passes through the gas outlet and extends to the interior of the pressure-stabilizing separation tank.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] refer to Figure 1 In an illustrative embodiment of a gas-liquid pressurization and separation device of the utility model, in the production process of an oil and gas field, the gas-liquid pressurization and separation device can be connected in series to a gas-liquid low-pressure pipeline, which can increase the output of the oil and gas field, reduce equipment investment, and reduce operation and maintenance costs, with huge benefits.

[0032] Continue to refer Figure 1 The gas-liquid pressurizing separation device may include an input mechanism 1, and the delivery mechanism has an input end and an output end. The input end of the delivery mechanism is connected to a gas-liquid low-pressure pipeline so that the gas-liquid mixture in the gas-liquid low-pressure pipeline enters the input mechanism 1.

[0033] It can be understood that the gas-liquid low-pressure pipeline can be a gas-liquid mixed transportation trunk line, and by serially connecting a gas-liquid pressurization and separation device, the gas-liquid mixture transported in the gas-liquid mixed transportation trunk line can be pressurized, separated and transported.

[0034] refer to Figure 1 A third valve is connected in series to the gas-liquid mixed transmission trunk line, and the input end of the input mechanism 1 is connected to the upstream of the third valve. When the gas-liquid mixed transmission trunk line flows into the gas-liquid pressurization separation device through the input mechanism 1, the third valve is closed. The third valve can be a manual ball valve or an electric ball valve.

[0035] The gas-liquid pressurization and separation device may include two reversing pressurization tanks 2 .

[0036] refer to Figure 1 , 3 The top of the reversing booster tank 2 has an inlet 22 and an outlet 23. The inlet 22 of the reversing booster tank 2 is connected to the output end of the input mechanism 1, so that the gas-liquid low-pressure pipeline conveys the gas-liquid mixture to the reversing booster tank 2 through the input mechanism 1.

[0037] The gas-liquid pressurizing separation device may include a pressure stabilizing separation tank 3. Figure 4 The top of the pressure stabilizing separation tank 3 is provided with an inlet 31 and an air outlet 32 ​​, and the bottom of the pressure stabilizing separation tank 3 is provided with a liquid outlet 33 .

[0038] The inlet 31 of the pressure stabilizing separation tank 3 is connected to the outlets 23 of the two reversing boosting tanks 2, so that the gas-liquid mixture in the reversing boosting tank 2 can be pressurized into the pressure stabilizing separation tank 3. The pressurized gas-liquid mixture can be stabilized and separated in the pressure stabilizing separation tank 3.

[0039] The liquid outlet 33 of the pressure-stabilizing separation tank 3 is connected to a liquid high-pressure pipeline, and the gas outlet 32 ​​of the pressure-stabilizing separation tank 3 is connected to a gas high-pressure pipeline.

[0040] The pressure-stabilizing separation tank 3 can stabilize the pressure, store energy, and separate the pressurized gas-liquid mixture, reduce the pressure fluctuation of the transportation, and the gas is transported to the gas high-pressure pipeline through the gas outlet 32, and the liquid is transported to the liquid high-pressure pipeline through the liquid outlet 33, which can save the subsequent separation equipment and the investment of separate transportation equipment. There is no need to use a compressor or pump to separate and extract the gas and liquid separately, so it is avoided that the gas will carry some liquid molecules into the compressor and be damaged, and the transportation efficiency of the gas and liquid is improved.

[0041] It is understandable that the reversing booster tank 2 and the pressure stabilizing separation tank 3 have hollow volumes, which can be used to store a gas-liquid mixture. The gas-liquid mixture can be a mixture composed of petroleum, natural gas, water, and the like.

[0042] In the initial state of the gas-liquid boosting and separation device, a preset volume of water is pre-stored in the two reversing boosting tanks 2. In this embodiment, the two reversing boosting tanks 2 and the pressure stabilizing separation tank 3 are both pressure tanks.

[0043] The gas-liquid pressurizing and separating device may include a reversing mechanism 4. Figure 1 , Figure 2 The reversing mechanism 4 is connected between the two reversing booster tanks 2 to drive the water in the two reversing booster tanks 2 to circulate back and forth.

[0044] It can be understood that the reversing mechanism 4 can form a channel for the drive fluid in the two reversing booster tanks 2 to circulate back and forth.

[0045] The gas-liquid mixture delivered by the input mechanism 1 to the two reversing booster tanks 2 is located above the water level. When the reversing mechanism 4 drives the water in the two reversing booster tanks 2 to circulate back and forth, the gas-liquid mixture in the gas-liquid low-pressure pipeline is sucked into the reversing booster tank 2 with a low water level through the input mechanism 1, and the gas-liquid mixture in the other reversing booster tank 2 is pressurized to the pressure stabilizing separation tank 3, wherein the gas enters the gas high-pressure pipeline through the gas outlet 32, and the liquid enters the liquid high-pressure pipeline through the liquid outlet 33.

[0046] In this embodiment, when the water in the two reversing booster tanks 2 circulates back and forth, the reversing booster tank 2 with a low water level absorbs the gas-liquid mixture through the input mechanism 1, and the gas-liquid mixture in the reversing booster tank 2 with a high water level is pressurized and discharged into the pressure stabilizing separation tank 3, where pressure stabilization and separation are performed to achieve continuous pressurized extraction and separate transportation of the gas-liquid mixture.

[0047] Exemplarily, the gas-liquid mixture delivered by the gas-liquid low-pressure pipeline to the 1# tank and the 2# tank through the input mechanism 1 is located above the water level. Figure 2 , the two reversing booster tanks 2 are 1# tank and 2# tank respectively, and the pressure stabilizing separation tank 3 is 3# tank. When 1# tank delivers water to 2# tank through the reversing mechanism 4, the expansion pressure of the gas space in 1# tank decreases due to the water level drop, and the gas-liquid mixture in the gas-liquid low-pressure pipeline is absorbed by the negative pressure. The pressure of the compressed gas space in 2# tank increases due to the water level rise, so that the gas-liquid mixture in 2# tank is pressurized and discharged to 3# tank. The liquid level in 3# tank rises, and the gas is transported to the gas high-pressure pipeline through the high pressure; the liquid level in 3# tank rises, so that the liquid is transported to the liquid high-pressure pipeline.

[0048] The utility model provides a gas-liquid boosting and separation device, which has a simple structure and is easy to operate. It uses water as a sealing piston to achieve zero leakage. The gas-liquid mixture is sucked in and out by raising and lowering the water level in the two reversing boosting tanks 2. The gas-liquid mixture is separated by the driving liquid, i.e., water, to ensure that the gas-liquid mixture cannot be sucked into the reversing mechanism 4, thereby ensuring the reliability of the gas-liquid boosting and separation device.

[0049] In some embodiments of the present application, the gas-liquid pressurization separation device may include an output mechanism.

[0050] refer to Figure 1 , Figure 2 The output mechanism may include a first pipeline 5 . One end of the first pipeline 5 is connected to the gas high-pressure pipeline, and the other end of the first pipeline 5 passes through the gas outlet 32 ​​and extends to the interior of the pressure-stabilizing separation tank 3 .

[0051] A first float valve is provided on the first pipeline 5, and the first float valve is located below the gas outlet 32. The first float valve is suitable for opening or closing the first pipeline 5 according to the liquid level of the pressure stabilizing separation tank 3, that is, opening and closing the gas outlet 32 ​​according to the liquid level.

[0052] In this embodiment, when the liquid level in the pressure stabilizing separation tank 3 is higher than the closing liquid level of the first float valve, the first float valve is closed to prevent the liquid in the pressure stabilizing separation tank 3 from flowing out of the first float valve to the gas high-pressure pipeline.

[0053] refer to Figure 1 , Figure 2The output mechanism may include a second pipeline 6 . One end of the first pipeline is connected to the liquid high-pressure pipeline, and the other end of the second pipeline 6 passes through the liquid outlet 33 and extends to the interior of the pressure-stabilizing separation tank 3 .

[0054] A second float valve is provided on the second pipeline 6, and the second float valve is located in the pressure stabilizing separation tank 3 and above the liquid outlet 33. The second float valve is suitable for opening or closing the second pipeline 6 according to the liquid level of the pressure stabilizing separation tank 3, that is, opening or closing the liquid outlet 33 according to the liquid level.

[0055] In this embodiment, when the liquid level in the pressure stabilizing separation tank 3 is lower than the closing liquid level of the second float valve, the second float valve is closed to prevent the gas in the pressure stabilizing separation tank 3 from flowing out of the second float valve to the liquid high-pressure pipeline.

[0056] In some embodiments of the present application, a second valve 62 is provided on both the first pipeline 5 and the second pipeline 6, and the second valve 62 is used to open or close the first pipeline 5 and the second pipeline 6. The second valve 62 can be a manual ball valve or an electric ball valve.

[0057] Further, the output mechanism may include two third one-way valves E and F. The two third one-way valves E and F are respectively arranged on the first pipeline 5 and the second pipeline 6. Figure 1 , Figure 2 The gas in the pressure stabilizing separation tank 3 can enter the gas high-pressure pipeline through the third one-way valve E and the second valve 62 in sequence. The liquid level in the pressure stabilizing separation tank 3 can enter the liquid high-pressure pipeline through the third one-way valve F and the second valve 62 in sequence.

[0058] In some embodiments of the present application, reference Figure 2 The reversing mechanism 4 may include a water pump M. The water pump M serves as a power source for driving the water in the two reversing booster tanks 2 to circulate back and forth.

[0059] The reversing mechanism 4 may include two three-way electric ball valves, and the two three-way electric ball valves M1 and M2 cooperate to switch the flow direction of water in the two reversing booster tanks 2 .

[0060] The three-way electric ball valves M1 and M2 have a first interface, a second interface and a third interface. The first interfaces of the two three-way electric ball valves M1 and M2 are respectively connected to the side walls of the two reversing booster tanks 2 through pipelines. It can be understood that the pipelines are connected to the interior of the reversing booster tanks 2. The second interfaces of the two three-way electric ball valves are connected to the water inlet of the water pump M through pipelines, and the third interfaces of the two three-way electric ball valves are connected to the water outlet of the water pump M through pipelines.

[0061] It should be noted that a water inlet and outlet 21 may be provided on the side wall of the bottom of the reversing booster tank 2 , wherein the water inlet and outlet 21 is connected to the first interface of the three-way electric ball valve through a pipeline.

[0062] In this embodiment, two three-way electric ball valves are provided so that when the 1# tank delivers the driving liquid to the 2# tank, or when the 2# tank delivers the driving liquid to the 1# tank, the water pump M always delivers the driving liquid in one direction, that is, the water pump M does not need to rotate forward or reverse. The flow direction of the driving liquid is controlled by controlling the opening and closing of the two three-way electric ball valves, thereby avoiding the situation where the water pump M is damaged due to frequent forward and reverse rotation.

[0063] Exemplarily, the reversing mechanism 4 may be connected to the bottom of the two reversing booster tanks 2 so as to pump the liquid at the bottom of the two reversing booster tanks 2 through the water pump M.

[0064] In some embodiments of the present application, a water level detection element for detecting the water level is provided in the reversing booster tank 2, and the water level detection element can detect at least two water levels.

[0065] The reversing mechanism 4 is configured to conduct the reversing flow according to the water level in the reversing booster tank 2. The detection element may be a liquid level gauge.

[0066] Specifically, the two reversing and boosting tanks 2 are each provided with a water level detection element, and the water level detection element is used to detect the height of the driving liquid (water) in the reversing and boosting tank 2, that is, the water level.

[0067] When one water level detection element detects that the water level in the reversing booster tank 2 where it is located exceeds the high water level threshold (or preset threshold), and another water level detection element detects that the water level in the reversing booster tank 2 where it is located is lower than the low water level threshold, the reversing mechanism 4 switches the flow direction of water between the two reversing booster tanks 2.

[0068] For example, when the reversing mechanism 4 is started, the water in the 1# tank is pumped to the 2# tank through the reversing mechanism 4 along the direction of the three-way electric ball valve M1, the water pump M, and the three-way electric ball valve M2; in this process, the gas-liquid mixture of the low-pressure gas-liquid pipeline is sucked into the 1# tank through the input mechanism 1, and the gas-liquid mixture of the 2# tank is pressurized to the 3# tank. The liquid level in the 3# tank rises, and the gas is transported to the gas high-pressure pipeline through the first pipeline 5 through the high pressure; the liquid level in the 3# tank rises, so that the liquid second pipeline 6 is transported to the liquid high-pressure pipeline.

[0069] When the water level detection element in the 1# tank detects that the water level is lower than the low water level threshold, and the water level detection element in the 2# tank detects that the water level exceeds the high water level threshold, the directions of the two three-way electric ball valves are switched, and the water in the 2# tank is pumped to the 1# tank through the reversing mechanism 4 along the direction of M2, water pump M, and M1. In this process, the gas-liquid mixture of the low-pressure gas-liquid pipeline is sucked into the 2# tank through the input mechanism 1, and the gas-liquid mixture of the 1# tank is pressurized to the 3# tank. The liquid level in the 3# tank rises, and the gas is transported to the gas high-pressure pipeline through the first pipeline 5 through the high pressure; the liquid level in the 3# tank rises, so that the liquid is transported to the liquid high-pressure pipeline through the second pipeline 6.

[0070] In some embodiments of the present application, the gas-liquid boosting and separation device may include a control system. The control system is electrically connected to the water level detection element and the reversing mechanism 4. The control system controls the reversing mechanism 4 to switch the flow direction of water between the two reversing boosting tanks 2 based on the water level in the reversing boosting tank 2.

[0071] In this embodiment, the conduction and reversing of the reversing mechanism 4 are controlled by utilizing the water level in the reversing booster tank 2 to ensure the accuracy of each displacement, ensure that the gas-liquid mixture cannot be sucked into the water pump M, and ensure the operational reliability of the gas-liquid boosting and pressurizing device. This avoids the situation where, after a period of operation, the water in the mixing mechanism is quickly discharged due to the inability to accurately control the liquid level, the uncertainty of the gas-liquid state, impurities such as sand and stones, and other uncontrollable problems, thereby preventing the water pump M from sucking in the gas-liquid mixture.

[0072] In some embodiments, the input mechanism 1 may include an input manifold 11 and two branch pipelines 13 .

[0073] One end of the input manifold 11 is connected to the gas-liquid low-pressure pipeline, and the other end of the input manifold 11 is connected to the inlets 22 of the two reversing booster tanks 2 through two branch pipelines 13 .

[0074] The input mechanism 1 may include a first valve 12. The first valve 12 is disposed on the input manifold 11 to open or close the input manifold 11. The first valve 12 may be a manual ball valve or an electric ball valve.

[0075] In some embodiments of the present application, the input mechanism 1 may include two first one-way valves A and C. The two first one-way valves A and C are respectively arranged on two branch pipelines 13 to allow the airflow mixture to flow into the reversing boost tank 2 through the input mechanism 1 in one direction.

[0076] The air flow mixture in the gas-liquid low-pressure pipeline can flow into the 1# tank via the first one-way valve A, or can flow into the 2# tank via the first one-way valve C.

[0077] In some embodiments of the present application, a second one-way valve is provided at the outlet 23 of the two reversing booster tanks 2 .

[0078] Specifically, refer to Figure 1 The gas-liquid boosting and separation device may include a connecting manifold 71 and two connecting pipes 72. One end of the connecting manifold 71 is connected to the inlet 31 of the pressure stabilizing and separating tank 3, and the other end thereof is connected to the outlet 23 of the reversing boosting tank 2 through the two connecting pipes 72.

[0079] The two connecting pipelines 72 are provided with second one-way valves, and the gas-liquid mixture in the reversing booster tank 2 can be one-way pressurized to the pressure stabilizing separation tank 3 through the second one-way valve.

[0080] refer to Figure 1 , the gas-liquid mixture in tank 1# can be pressurized into tank 3# through the second one-way valve B. The gas-liquid mixture in tank 2# can be pressurized into tank 3# through the second one-way valve D.

[0081] In some embodiments of the present application, the gas-liquid pressurization separation device may include a liquid inlet buffer plate 8.

[0082] There are three liquid inlet buffer plates 8, which are respectively arranged inside the reversing booster tank 2 and the pressure stabilizing separation tank 3. The liquid inlet buffer plates 8 inside the reversing booster tank 2 are arranged below the inlet 22. Similarly, the liquid inlet buffer plates 8 inside the pressure stabilizing separation tank 3 are arranged below the inlet 31.

[0083] In this embodiment, a liquid inlet buffer plate 8 is provided in the reversing booster tank 2 to prevent the gas-liquid mixture entering the reversing booster tank 2 through the inlet 22 from being miscible with the water inside due to pressure shock. By providing the liquid inlet buffer plate 8 in the pressure stabilizing separation tank 3, the pressure shock of the gas-liquid mixture at the inlet 31 can be prevented, and the pressure fluctuation of the delivery can be further reduced.

[0084] In some embodiments of the present application, at least one umbrella-shaped separation plate 9 is provided inside the reversing boost tank 2 and the pressure stabilizing separation tank 3. The umbrella-shaped separation plate 9 is located below the inlet 22 and the inlet 31, and a plurality of through holes are provided through the umbrella-shaped separation plate 9.

[0085] In this embodiment, the umbrella-shaped separation plate 9 can precipitate and separate solid impurities mixed in the gas-liquid mixture, and at the same time can break up the flocculent or lumpy liquid in the gas-liquid mixture, preventing it from sinking below the water surface in the reversing booster tank 2 due to the impact of the pressure at the inlet 22, and effectively preventing the reversing booster tank 2 from being unable to push out the gas-liquid mixture when filling water with water pump M.

[0086] refer to Figure 3 , Figure 4The umbrella-shaped separation plate 9 is arranged above the reversing supercharging tank 2 and the pressure stabilizing separation tank 3. By arranging the umbrella-shaped separation plate 9 at the inlet 22 of the reversing supercharging tank 2 and the inlet 31 of the pressure stabilizing separation tank 3, the reversing supercharging tank 2 and the pressure stabilizing separation tank 3 can both play a role of separation, so that the pressure stabilizing separation tank 3 has a better separation effect.

[0087] For further information, please refer to Figure 3 , Figure 4 The umbrella-shaped separation plate 9 is located below the liquid inlet buffer plate 8.

[0088] It should be noted that the volume of the reversing boost tank 2 can be set according to the displacement of the oil-gas mixture, extending the conversion time of the drive liquid, and better realizing the oil-gas-water separation, ensuring that the gas-liquid mixture cannot be sucked into the water pump M, thereby ensuring the reliability of the equipment.

[0089] In some embodiments of the present application, two reversing booster tanks 2 and one pressure stabilizing separation tank 3 may be designed as a three-in-one structure, that is, the three structures and functions of the two reversing booster tanks 2 and one pressure stabilizing separation tank are integrated into one tank body.

[0090] In some embodiments of the present application, the tank bodies with the two functions of the reversing booster tank 2 and the pressure stabilizing separation tank 3 can be composed of pressure tanks of different numbers and sizes.

[0091] Specifically, the reversing boost tank 2 may be configured in plurality, and the pressure stabilizing separation tank 3 may be configured in at least one.

[0092] The inlets 22 of the multiple reversing booster tanks 2 are connected to the input mechanism 1, so that the input mechanism 1 delivers the gas-liquid mixture to the reversing booster tank 2. Each reversing booster tank 2 is connected to one of the inlets 31 of at least one pressure stabilizing separation tank 3, so that the gas-liquid mixture in the reversing booster tank 2 can be pressurized to the pressure stabilizing separation tank 3, and the bottom of the pressure stabilizing separation tank 3 is provided with a liquid outlet 33 connected to the liquid high-pressure pipeline.

[0093] The reversing mechanism 4 is connected between two adjacent reversing booster tanks 2 to drive the water in the two reversing booster tanks 2 to circulate back and forth. The reversing mechanism 4 drives the water in the two adjacent reversing booster tanks 2 to flow from one to the other. In this process, the gas-liquid mixture in the gas-liquid low-pressure pipeline is sucked into the reversing booster tank 2 with a low water level, and the gas-liquid mixture in the other reversing booster tank 2 is pressurized to the pressure-stabilizing separation tank 3 connected thereto, wherein the gas enters the gas high-pressure pipeline through the gas outlet 32, and the liquid enters the liquid high-pressure pipeline through the liquid outlet 33.
