DETAILED DESCRIPTION

[0072] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0073] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0074] The gas-liquid cyclone separator provided by the embodiments of the present application will be described in detail below with reference to the specific embodiments and application scenarios thereof in combination with the accompanying drawings.

[0075] As shown in Figures 1-3 The present embodiment provides an oil-gas-water automatic measuring device, which comprises a mounting base 16, a feed pipe 1, a discharge pipe 9, a gas-liquid cyclone separator 21 substantially perpendicular to the mounting base 16, a liquid-phase flowmeter 14, a gas-phase flowmeter 12, a gas conveying pipe 11 and an oil conveying pipe 13,

[0076] One end of the gas-liquid cyclone separator 21 is fixed to the mounting base 16;

[0077] One end of the feed pipe 1 is in communication with the gas-liquid cyclone separator 21;

[0078] One end of the gas conveying pipe 11 is in communication with the other end of the gas-liquid cyclone separator 21, and the other end is in communication with the discharge pipe 9;

[0079] One end of the oil conveying pipe 13 is in communication with one end of the gas-liquid cyclone separator 21, and the other end is in communication with the discharge pipe 9;

[0080] The liquid-phase flowmeter 14 is arranged at the oil conveying pipe 13, and the gas-phase flowmeter 12 is arranged at the gas conveying pipe 11.

[0081] In the present embodiment, the gas-liquid cyclone separator 21 used is a gas-liquid cyclone separator 21 for separating oil, gas and water in the prior art; the liquid-phase flowmeter 14 is a Coriolis mass flowmeter; and the gas-phase flowmeter 12 is a gas ultrasonic flowmeter;

[0082] In the present embodiment, a protective shell 17 is further arranged on the mounting base 16 to protect the internal devices;

[0083] In use, first, oil, gas and water are conveyed to the feed pipe 1 through a pipeline, and then transported to the gas-liquid cyclone separator 21 in the feed pipe 1. Under the separation action of the gas-liquid cyclone separator 21, the oil, gas and water are separated into oil-water and gas. At this time, the oil-water is at one end of the gas-liquid cyclone separator 21, and the gas is at the other end of the gas-liquid cyclone separator 21, so as to realize that the oil-water flows into the oil conveying pipe 13 from one end of the gas-liquid cyclone separator 21, and the gas flows into the gas conveying pipe 11 from the other end of the gas-liquid cyclone separator 21. The oil-water is metered by the liquid-phase flowmeter 14 when flowing in the oil conveying pipe 13, and the gas is metered by the gas-phase flowmeter 12 when flowing in the gas conveying pipe 11. After metering, the oil-water and the gas are transported to the discharge pipe 9 by the oil conveying pipe 13 and the gas conveying pipe 11 respectively, and then discharged from the discharge pipe 9 after being combined;

[0084] It should be noted that after the gas-liquid cyclone separator 21 realizes the separation function, the oil and water and the gas are respectively at both ends of the gas-liquid cyclone separator 21, so that the oil and water flow out from one end of the gas-liquid cyclone separator 21, and the gas flows out from the other end of the gas-liquid cyclone separator 21, realizing the mutual independent transportation and metering of the oil and water and the gas, thereby avoiding the mutual influence of the subsequent oil and water and the gas, and causing the decrease of the metering accuracy.

[0085] In the embodiment, the shunt pipe 19 is further included, and the number of the gas-liquid cyclone separators 21 is multiple;

[0086] The shunt pipe 19 is provided with one inlet end 18 and multiple outlet ends 20, the number of the outlet ends 20 corresponds to the number of the gas-liquid cyclone separators 21, the inlet end 18 is connected with one end of the feed pipe 1, and the outlet ends 20 are connected with the corresponding gas-liquid cyclone separators 21.

[0087] Through the structure in the embodiment, when the feed pipe 1 transports the oil, gas and water to the shunt pipe 19, the oil, gas and water first enter the shunt pipe 19 from the inlet end 18, and when the oil, gas and water flow to the outlet ends 20, they flow out through the different outlet ends 20, thereby flowing into the different gas-liquid cyclone separators 21 for separation, realizing the shunting.

[0088] It is worth mentioning that under the setting of multiple gas-liquid cyclone separators 21, the oil, gas and water that can be processed by the oil, gas and water automatic metering device in the embodiment is more in the same time period, further improving the working efficiency; at the same time, the working load of a single gas-liquid cyclone separator 21 can be effectively avoided, so that the oil, gas and water flow out of the gas-liquid cyclone separator 21 before being effectively separated, resulting in poor separation effect and the problem of decreased metering accuracy;

[0089] It should be noted that as for the setting of the shunt pipe 19, the outlet ends 20 can be designed in a detachable manner, so that in actual use, the number of the outlet ends 20 can be increased or decreased according to actual needs, thereby the number setting of the gas-liquid cyclone separators 21 can be increased or decreased, so as to meet different use requirements and achieve better use effect.

[0090] In the embodiment, one end of the gas conveying pipe 11 is provided with the first branch pipes 10 corresponding to the number of the gas-liquid cyclone separators 21, and the gas conveying pipe 11 is connected with the corresponding gas-liquid cyclone separators 21 through the first branch pipes 10.

[0091] Through the structure in the embodiment, the gas separated out by the gas-liquid cyclone separators 21 can flow into the first branch pipes 10 from the other end of the gas-liquid cyclone separators 21, and the gas in the multiple first branch pipes 10 can finally converge in the gas conveying pipe 11, be transported to the gas phase flow meter 12 through the gas conveying pipe 11, and be transported to the discharge pipe 9 after metering.

[0092] It is worth mentioning that the oil, gas and water are separated by the plurality of gas-liquid cyclone separators 21, that is, the gas is diluted in different gas-liquid cyclone separators 21, the gas in the different gas-liquid cyclone separators 21 is guided out through the first branch pipe 10 and finally gathered in the gas conveying pipe 11 for metering, which can preferably ensure the accuracy of the gas phase flowmeter 12 in metering the gas.

[0093] In the embodiment, one end of the oil conveying pipe 13 is provided with a second branch pipe 22 corresponding in number to the gas-liquid cyclone separators 21, and the oil conveying pipe 13 is connected in communication with the gas-liquid cyclone separators 21 at the corresponding positions through the second branch pipe 22.

[0094] Through the structure in the embodiment, the oil and water separated by the gas-liquid cyclone separators 21 can flow into the second branch pipe 22 from one end of the gas-liquid cyclone separators 21, and the oil and water in the plurality of second branch pipes 22 can finally be gathered in the oil conveying pipe 13, transported to the liquid phase flowmeter 14 through the oil conveying pipe 13, and transported to the discharge pipe 9 after metering;

[0095] It is worth mentioning that the oil, gas and water are separated by the plurality of gas-liquid cyclone separators 21, that is, the gas is diluted in different gas-liquid cyclone separators 21, the gas in the different gas-liquid cyclone separators 21 is guided out through the first branch pipe 10 and finally gathered in the gas conveying pipe 11 for metering, which can preferably ensure the accuracy of the gas phase flowmeter 12 in metering the gas.

[0096] In the embodiment, the other end of the gas-liquid cyclone separator 21 is connected in communication with the corresponding first branch pipe 10 through the first valve 3.

[0097] Through the setting of the first valve 3, the gas-liquid cyclone separator 21 and the first branch pipe 10 can be disconnected and conducted;

[0098] It should be noted that there are at least the following three cases for the installation position of the first valve 3:

[0099] 1) The first valve 3 is installed on the other end of the gas-liquid cyclone separator 21;

[0100] 2) The first valve 3 is installed on the first branch pipe 10;

[0101] 3) The first valve 3 is installed between the other end of the gas-liquid cyclone separator 21 and the first branch pipe 10, that is, at the connection.

[0102] In the embodiment, the first check valve 4 is arranged at the gas conveying pipe 11.

[0103] By setting the first check valve 4, the one-way transportation of gas by the gas pipe 11 can be realized, and the problem of gas backflow is avoided, which affects the metering of gas;

[0104] It should be noted that there are at least the following two cases for the installation position of the first check valve 4:

[0105] 1) on the gas pipe 11 and at the side of the gas phase flow meter 12 close to the gas-liquid cyclone separator 21;

[0106] 2) on the gas pipe 11 and at the side of the gas phase flow meter 12 away from the gas-liquid cyclone separator 21.

[0107] In this embodiment, the second check valve 5 is arranged at the oil pipe 13.

[0108] By setting the second check valve 5, the one-way transportation of oil and water by the oil pipe 13 can be realized, and the problem of oil and water backflow is avoided, which affects the metering of oil and water;

[0109] It should be noted that there are at least the following two cases for the installation position of the second check valve 5:

[0110] 1) on the oil pipe 13 and at the side of the liquid phase flow meter 14 close to the gas-liquid cyclone separator 21;

[0111] 2) on the oil pipe 13 and at the side of the liquid phase flow meter 14 away from the gas-liquid cyclone separator 21.

[0112] In this embodiment, it also includes a second valve 2, a third valve 6, a connecting pipe 7 and a fourth valve 8,

[0113] The second valve 2 is arranged at the feed pipe 1; the third valve 6 is arranged at the discharge pipe 9; and the fourth valve 8 is arranged at the connecting pipe 7;

[0114] One end of the connecting pipe 7 is connected to the side of the feed pipe 1 away from the gas-liquid cyclone separator 21 and the other end is connected to the side of the discharge pipe 9 away from the gas-liquid cyclone separator 21.

[0115] Through the structure in this embodiment, when the oil-gas-water automatic measuring device in this embodiment is maintained or parts are replaced, first, the second valve 2 and the third valve 6 are closed, the fourth valve 8 is opened, so that the oil-gas-water from the feed pipe 1 directly flows into the connecting pipe 7, and then flows into the discharge pipe 9 and is discharged, realizing circulation, thereby temporarily stopping the separation and metering of oil-gas-water, and achieving the purpose of maintaining or replacing parts of the equipment;

[0116] Then, open the second valve 2 and the third valve 6, and close the fourth valve 8, so that the feed pipe 1 can transport oil, water and gas to the gas-liquid cyclone separator 21, and then separate and meter the oil, gas and water.

[0117] It is worth mentioning that when the automatic oil, gas and water measuring device in this embodiment is maintained or parts are replaced, the circulation of oil, gas and water can be achieved through the connection of the inlet, connecting pipe 7 and outlet, so as not to affect the subsequent processing of oil, gas and water, and to ensure the normal operation of the work.

[0118] In this embodiment, a drain valve 15 is installed at one end of the gas-liquid cyclone separator 21 via a pipe.

[0119] After prolonged use, some oil and water will accumulate and adhere to one end of the gas-liquid cyclone separator 21, affecting the separation efficiency and subsequent metering. Therefore, the drain valve 15 in this embodiment enables the periodic cleaning of the gas-liquid cyclone separator 21. By opening the drain valve 15, some of the oil and water accumulated in the gas-liquid cyclone separator 21 can be discharged, thereby effectively ensuring the normal and effective operation of the gas-liquid cyclone separator 21 and further ensuring the accuracy of subsequent metering.

[0120] It should be noted that, since the gas separated in the gas-liquid cyclone separator 21 is prone to expansion due to the influence of temperature and pressure, a pressure relief valve can be installed at the gas-liquid cyclone separator 21 to ensure safe operation. This valve allows the gas in the gas-liquid cyclone separator 21 to be discharged as needed to ensure safety.

[0121] In the actual production process, the various components in this embodiment can be supported by a support frame 23 on the mounting base 16 according to the actual situation.

[0122] like Figures 4-10 As shown, this embodiment provides a gas-liquid cyclone separator 21, including a tank 2101, a separation chamber 2102 inside the tank 2101, a support 2106 fixedly provided at the bottom of the tank 2101 for supporting the tank 2101, a separation component inside the separation chamber 2102, an inlet 2138 communicating with the separation chamber 2102 on the side of the tank 2101 away from the support 2106, and a drain 2139 communicating with the separation chamber 2102 on the side of the separation component close to the support 2106, an inlet pipe 2105 communicating with the inlet 2138 fixedly provided on the tank 2101 at a position corresponding to the inlet 2138, and a drain pipe 2104 communicating with the drain 2139 fixedly provided at a position corresponding to the drain 2139, an outlet end 20 connected to the inlet pipe 2105, and a second branch pipe 22 connected to the drain pipe 2104.

[0123] The gas-liquid cyclone separator 21 provided in the embodiment further comprises an exhaust pipe 2116 located at the side of the liquid inlet pipe 2105 away from the separation assembly, and the exhaust pipe 2116 is provided with an exhaust passage 2128 capable of communicating with the separation chamber 2102. The exhaust pipe 2116 is connected to the corresponding first branch pipe 10 through the first valve 3.

[0124] The gas-liquid cyclone separator 21 provided in the embodiment further comprises a blowdown pipe 2104 arranged at the bottom of the tank body 2101 and communicating with the separation chamber 2102. The blowdown valve 15 is arranged on the blowdown pipe 2104 and capable of opening and closing the blowdown pipe 2104.

[0125] In the embodiment, the above-mentioned gas-liquid cyclone separator 21 is adopted. When the gas-liquid mixed fluid enters the separation chamber 2102 through the liquid inlet pipe 2105, the gas-liquid is separated by the separation assembly. The separated liquid is discharged through the liquid outlet pipe 2103, and the separated gas is discharged through the exhaust pipe 2116 due to the smaller density. The blowdown pipe 2104 is controlled to be closed by the first valve 3 during normal operation of the gas-liquid cyclone separator 21. When too much dirt accumulates in the separation chamber 2102, the blowdown pipe 2104 is opened by the first valve 3 to discharge the dirt accumulated in the separation chamber 2102.

[0126] In a preferred embodiment, as shown in Figure 4 , the separation chamber 2102 is in a cylindrical shape, and the flow directions of the fluids in the liquid inlet pipe 2105 and the liquid outlet pipe 2103 are not in the radius direction of the horizontal section of the separation chamber 2102.

[0127] In the embodiment, the above-mentioned gas-liquid cyclone separator is adopted. The flow directions of the liquid inlet pipe 2105 and the liquid outlet pipe 2103 are eccentrically arranged. When the gas-liquid mixed fluid flows into the separation chamber 2102, the mixed fluid will hit the inner wall of the separation chamber 2102 to realize cyclone flow in the separation chamber 2102. The separated liquid is subjected to the eccentric effect of the liquid outlet pipe 2103 to realize cyclone flow. Under the action of the cyclone flow of the fluid in the separation chamber 2102, the mixed fluid realizes gas-liquid separation under the action of centrifugal force, thereby improving the gas-liquid separation efficiency. The separated liquid further separates the gas through cyclone flow, thereby improving the gas-liquid separation effect.

[0128] In a preferred embodiment, as shown in Figure 1 , Figures 5-7 , the separation assembly comprises a separation plate 2108 arranged obliquely in the separation chamber 2102. A plurality of impact rods 2109 are arranged and fixed on the end face of the separation plate 2108 away from the support 2106. A plurality of leakage holes 2140 are provided through the separation plate 2108.

[0129] In a preferred embodiment, the inclined direction of the separation plate 2108 is close to the liquid inlet 2138, and four support plates 2107 are fixed on the inner wall of the separation cavity 2102 for supporting the separation plate 2108, one of the support plates 2107 is located at the position corresponding to the lowest point of the separation plate 2108, one of the support plates 2107 is located at the position corresponding to the highest point of the separation plate 2108, and the other two support plates 2107 are located at the positions between the lowest point and the highest point of the separation plate 2108.

[0131] In the embodiment of the present application, the above-mentioned gas-liquid cyclone separator 21 is adopted, when the gas-liquid mixed fluid flows into the separation cavity 2102, the mixed fluid will impact the inner wall of the separation cavity 2102 to realize the cyclone flow in the separation cavity 2102, and the mixed fluid will impact the impact rod 2109 to realize the turbulent flow, thereby realizing the separation of the gas and the liquid, the separated liquid flows downward through the leakage hole 2140 and is discharged through the liquid outlet 2139, wherein the separation plate 2108 is arranged in an inclined manner, which increases the impact area of the mixed fluid and further enhances the cyclone flow intensity, thereby improving the gas-liquid separation efficiency and separation effect.

[0133] The gas valve assembly comprises a connecting cylinder 2111 fixed on the end face of the tank body 2101 away from the support 2106, a sensing cavity 2112 is provided through the connecting cylinder 2111 and communicates with the separation cavity 2102, a fixed seat 2113 is fixedly sleeved on the side end of the connecting cylinder 2111 away from the tank body 2101, a cavity 2132 is provided through the fixed seat 2113 and communicates with the sensing cavity 2112, an end cover 2114 is fixed on the side end face of the fixed seat 2113 away from the connecting cylinder 2111, an exhaust pipe 2116 is fixed on the side end face of the end cover 2114 away from the fixed seat 2113, a communication cavity 2127 is provided in the end cover 2114 and communicates with the exhaust passage 2128, a sealing cavity 2122 is provided in the end cover 2114 and opens to the side away from the exhaust pipe 2116 and communicates with the communication cavity 2127, an installation plate 2117 is fixed on the side end face of the end cover 2114 away from the exhaust pipe 2116 and is located in the cavity 2132, a plurality of through holes 2129 are provided through the installation plate 2117, a transition cavity 2115 is provided through the end cover 2114 and communicates with the through holes 2129 and the sealing cavity 2122 at positions corresponding to the through holes 2129, a top rod 2120 coupled with the feedback assembly is slidably provided in the installation plate 2117, a sliding cylinder 2118 is fixed on the inner wall of the sealing cavity 2122, a sliding cavity 2119 is provided in the sliding cylinder 2118 and communicates with the sealing cavity 2122, a sliding block 2121 is slidably provided in the sliding cavity 2119 and is fixedly connected with the top rod 2120 at the side end close to the exhaust pipe 2116, a sealing cylinder 2125 is fixed on the side end face of the sliding block 2121 away from the top rod 2120 and can slide in the communication cavity 2127, an opening and closing plate 2126 is fixed on the outer surface of the sealing cylinder 2125 and can completely cover and close the communication cavity 2127.

[0134] In the embodiment of the present application, the above-mentioned gas-liquid cyclone separator 21 is adopted. When the liquid in the separation chamber 2102 is in a normal state, the feedback assembly controls the gas valve assembly to connect the exhaust passage 2128 and the separation chamber 2102. At this time, the opening and closing plate 2126 does not cover and close the communication chamber 2127. The communication chamber 2127, the sealing chamber 2122, the transition chamber 2115, the through hole 2129, the cavity 2132, and the induction chamber 2112 form a flow path between the exhaust passage 2128 and the separation chamber 2102. The gas separated by the separation assembly is discharged through the exhaust pipe 2116. When the liquid in the separation chamber 2102 accumulates too much due to a small amount of gas, the feedback assembly controls the gas valve assembly to close the communication path between the exhaust passage 2128 and the separation chamber 2102, that is, the top rod 2120 is pushed to drive the sliding block 2121, the sealing cylinder 2125, and the opening and closing plate 2126 to move towards the side close to the exhaust pipe 2116. The opening and closing plate 2126 completely covers and closes the communication chamber 2127. At this time, the gas in the separation chamber 2102 cannot be discharged through the exhaust pipe 2116, but accumulates in the top position of the separation chamber 2102 under the action of its own density. At this time, the liquid in the separation chamber 2102 is pressed by the gas, and the flow rate of the liquid discharged through the liquid discharge pipe 2103 increases, thereby avoiding the overflow of the liquid in the separation chamber 2102 from the exhaust pipe 2116 due to the accumulation of too much liquid, that is, the stability and reliability of the gas-liquid separation are ensured, and the gas-liquid separation effect is further ensured.

[0135] In a preferred embodiment, as shown in Figure 2 , the gas valve assembly further comprises a first annular groove 2123 arranged on the inner wall of the sealing chamber 2122 close to the side of the exhaust pipe 2116 and surrounding the opening of the corresponding position of the communication chamber 2127. A first sealing ring 2124 is arranged in the first annular groove 2123 and can abut against the corresponding side end face of the opening and closing plate 2126. When the opening and closing plate 2126 completely covers and closes the communication chamber 2127, the opening and closing plate 2126 abuts against the first sealing ring 2124, thereby ensuring the sealing performance between the sealing chamber 2122 and the communication chamber 2127.

[0136] In a preferred embodiment, as shown in Figure 3 , the gas valve assembly further comprises a second annular groove 2130 arranged on the side end face of the fixed seat 2113 close to the exhaust pipe 2116 and surrounding the opening of the corresponding position of the cavity 2132. A second sealing ring 2131 is arranged in the second annular groove 2130 and abuts against the corresponding side end face of the end cover 2114. When the fixed seat 2113 and the end cover 2114 are fixedly connected, the second sealing ring 2131 can ensure the sealing performance between the fixed seat 2113 and the end cover 2114, thereby preventing leakage.

[0137] In a preferred embodiment, as shown in Figure 1 , Figure 3As shown, the feedback assembly includes an arc rod 2133 fixedly arranged on the mounting plate 2117 away from the side end face of the exhaust pipe 2116 and in sliding connection with the top rod 2120, one end of the arc rod 2133 is hingedly provided with a sensing swing rod 2135, the sensing swing rod 2135 is hingedly provided with a connecting seat 2136 away from the side end of the hinged point with the arc rod 2133, the connecting seat 2136 is fixedly provided with a float ball 2110 located in the sensing cavity 2112, the other end of the arc rod 2133 is hingedly provided with a feedback swing rod 2141, the feedback swing rod 2141 is hingedly provided with a linkage rod 2134 away from the side end of the hinged point with the arc rod 2133, the linkage rod 2134 is hingedly connected to the middle part of the sensing swing rod 2135 away from the side end of the hinged point with the feedback swing rod 2141, and the middle part of the driven rod 2137 is also hingedly provided with a driven rod 2137, the driven rod 2137 is hingedly connected to the top rod 2120 away from the side end of the feedback swing rod 2141.

[0138] When the amount of liquid in the separation cavity 2102 is too much, the float ball 2110 moves to the side close to the exhaust pipe 2116 under the action of buoyancy, so that the sensing swing rod 2135 swings and drives the linkage rod 2134 to move to the side close to the exhaust pipe 2116, the linkage rod 2134 drives the feedback swing rod 2141 to swing to the side close to the exhaust pipe 2116, so that the driven rod 2137 pushes the top rod 2120 to the side close to the exhaust pipe 2116, and then the opening and closing plate 2126 completely covers and closes the communication cavity 2127, realizing the discharge limitation of the gas in the separation cavity 2102, and preventing the liquid from overflowing through the exhaust pipe 2116.

[0139] In the embodiment of the present application, the above-mentioned gas-liquid cyclone separator 21 is adopted, the height of the liquid in the separation cavity 2102 is sensed by the float ball 2110, when the amount of liquid is too much, the linkage rod assembly is driven by the buoyancy of the float ball 2110 to control the gas valve assembly to close the exhaust pipe 2116, so as to realize the adaptive adjustment of the pressure in the separation cavity 2102, prevent liquid leakage, improve the gas-liquid separation efficiency and separation effect, and have stronger stability and reliability.

[0140] It can be understood that the feedback assembly is mainly used for sensing the height of the liquid in the separation cavity 2102 and coupling control of the opening and closing of the gas valve assembly, the structure of the present application is not limited to the above-mentioned one, for example, the linkage rod structure between the float ball 2110 and the top rod 2120 can be simplified, or the gas valve assembly can be set as electromagnetic control, and the feedback assembly can be set as a liquid level sensor or other electronic sensing element, and the gas valve assembly controls the exhaust pipe 2116 through the sensing result of the liquid level sensor.
