Description
Technical Field
The invention relates to the technical field of multiphase flow mixed transportation, in particular to a multiphase flow mixed transportation method and a multiphase flow mixed transportation device.
Background
For mixtures containing both gas and liquid phases, or mixtures containing both solid, gas and liquid phases, for example, for the transport of hydrocarbons in the oil field hydrocarbon recovery process. Due to the simultaneous existence of gas and liquid materials, the direct pumping is difficult to realize, so that the structures such as a pump and the like are free running and easy to damage. Therefore, solid, liquid and gas separation processes are usually performed first to facilitate separate transportation. The treatment process is complex in process flow, operation and maintenance.
In recent years, the application of multiphase mixed transportation pumps greatly improves the transportation efficiency of gas-liquid mixtures. However, in the process of conveying the gas-liquid mixture, the flow of the gas-liquid material is unstable, so that the requirements on the performance of the pump such as sealing and lubrication are high, and the service life and the efficiency of the pump are affected.
In the mixed material conveying technology, two tank bodies can be connected into a conveying pipeline, the two tank bodies are communicated through the pipeline, and a pump and a valve are arranged on the pipeline to adjust the flow direction of liquid between the two tank bodies. After the gas-liquid mixture enters the tank body, gas-phase substances and liquid-phase substances are separated; meanwhile, the conveying of the gas-liquid mixture can be realized by adjusting the flow direction of the liquid between the two tank bodies. The pump between the two tank bodies only relates to liquid conveying, so that the application of a multiphase mixed conveying pump can be avoided, and the cost and the maintenance difficulty are reduced. However, because the liquid level difference between the two tank bodies is large, in the reversing process, large impact can be generated on a pump body on the pipeline, and the service life of a pumping structure on the pipeline can be influenced. In addition, after the gas-liquid mixture enters the tank body, the gas-liquid material is separated, so that the air pressure in the tank body can be changed, and if the air pressure is not adjusted in time, the feeding and discharging can be affected.

The following description is presented to enable any person skilled in the art to make and use the invention. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and processes are not shown in detail to avoid obscuring the description of the invention with unnecessary detail. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein. Unless otherwise specified, the directions of the present invention are not strictly parallel or perpendicular, and the like, as long as the corresponding structures can achieve the corresponding objects.
Referring to fig. 1, an embodiment of the invention provides a multiphase flow mixing transmission method, including:
s1, sucking the multiphase flow mixture to be conveyed into the first tank body;
s2, starting the reversing mechanism and adjusting the flow rate of liquid in the reversing mechanism, pumping the liquid in the first tank body into the second tank body through the reversing mechanism, compressing gas in the second tank body by the liquid in the second tank body, and discharging the multiphase flow mixture in the second tank body;
s3, switching the reversing mechanism and changing the flow direction and the flow rate of the liquid in the multiphase flow mixture in the reversing mechanism;
s4, sucking the multiphase mixture to be conveyed into a second tank body;
and S5, starting the reversing mechanism and adjusting the flow rate of liquid in the reversing mechanism, pumping the liquid in the second tank body into the first tank body through the reversing mechanism, compressing gas in the first tank body by the liquid entering the first tank body, and discharging the multiphase flow mixture in the first tank body.
The steps are circularly implemented, and the continuous conveying of the multiphase flow mixture can be realized. The multiphase flow mixture sucked into one of the first tank 100 and the second tank 200 is discharged from the other of the first tank 100 and the second tank 200 by regulating the flow direction of the liquid in the reversing mechanism between the first tank 100 and the second tank 200 so that the liquid in the first tank 100 and the second tank 200 is circulated back and forth between the first tank 100 and the second tank 200 to alternately form a vacuum suction cavity and/or a compression discharge cavity, thereby realizing the conveying of the multiphase flow mixture. In addition, in the conveying process, the air pressure in the two tank bodies can be conveniently regulated and controlled in real time by regulating and controlling the flow rate of liquid in the reversing mechanism, and the conveying efficiency is improved. Meanwhile, the liquid impact phenomenon during reversing can be effectively reduced by regulating and controlling the opening and closing speed of the valve in the reversing mechanism.
The multiphase flow mixing and conveying method of the embodiment of the invention is particularly suitable for conveying multiphase flow mixture containing gas and liquid at the same time, and can also be used for conveying materials containing solid, gas and liquid materials or other fluid materials at the same time.
Referring to fig. 2, the specific structure of the first and second tanks 100 and 200 is not limited as long as the multiphase flow mixture can be conveniently transported. The multiphase flow mixture to be delivered is taken as an example to be sucked into the first tank 100. The specific way of sucking the multiphase flow mixture to be transported into the first tank 100 is to pump the liquid in the first tank 100 into the second tank 200, so that the volume of the liquid in the first tank 100 is reduced, and then a negative pressure is generated in the first tank 100 to form a vacuum suction cavity, thereby achieving the purpose of sucking the multiphase flow mixture to be transported into the first tank 100. Meanwhile, as the liquid in the first tank 100 is pumped into the second tank 200, the volume of the liquid in the second tank 200 is increased accordingly, thereby forming a compression discharge chamber in the second tank 200. Similarly, when the liquid in the second tank 200 is transferred into the first tank 100, a vacuum suction chamber can be formed in the second tank 200, and a compression discharge chamber can be formed in the first tank 100, and the detailed operation process is not repeated here.
A reversing mechanism is further arranged between the first tank 100 and the second tank 200, and the specific structure of the reversing mechanism is not particularly limited as long as the reversing mechanism can drive the liquid in the first tank 100 and the second tank 200 to circulate between the first tank 100 and the second tank 200. By changing the flow direction of the liquid in the reversing mechanism, the liquid in the first tank 100 can enter the second tank 200, or the liquid in the second tank 200 can enter the first tank 100. It can be understood that the position where the reversing mechanism is respectively communicated with the first tank 100 and the second tank 200 is generally located at the lower part of the first tank 100 and the second tank 200, and is close to the bottom of each tank, and the specific position can be adjusted according to the actual requirement.
The reversing mechanism comprises a power pump 31, a communication line 32, at least one drive mechanism and at least one valve. One end of the communication line 32 communicates with the first tank 100, and the other end communicates with the second tank 200. The power pump 31 and the valves are provided on the communication line 32. The flow direction of the liquid in the reversing mechanism is switched by switching the on-off state of the valve or switching the port through which the reversing valve is communicated with the communication pipeline 32, so that the liquid in the first tank 100 and the second tank 200 can flow back and forth between the two tanks. Meanwhile, the flow rate of the liquid in the reversing mechanism is regulated and controlled, so that the amount of the multiphase flow mixture entering one tank body and the amount of the multiphase flow mixture discharged by the other tank body are adaptive to the reciprocating flow rate of the liquid between the two tank bodies, the phenomenon that the suction efficiency is influenced due to overlarge air pressure in the tank body forming the vacuum suction cavity is avoided, and the phenomenon that the discharge efficiency is influenced due to the undersize air pressure in the tank body forming the compression discharge cavity is avoided. And moreover, by controlling the flow rate of the liquid in the reversing mechanism, the liquid impact phenomenon in the reversing process can be effectively reduced or avoided.
The following description will be given taking as an example a structure in which the reversing mechanism includes four valves. Specifically, the communication line 32 for communicating the first tank 100 and the second tank 200 may include a first line 301, a second line 302, and a third line 303. A first end of the first pipeline 301 is communicated with the first tank 100, and a second end of the first pipeline 301 is communicated with the second tank 200; a first end of the second pipeline 302 is in communication with the first tank 100, and a second end of the second pipeline 302 is in communication with the second tank 200; a first end of the third line 303 communicates with the first line 301 at a first communication position 33; a second end of the third line 303 communicates with the second line 302 at a second communication position 34.
The power pump 31 is arranged on the third pipeline 303, and the first valve 305 and the second valve 307 are arranged on the first pipeline 301; also, a first valve 305 and a second valve 307 are located on opposite sides of the first communication location 33, respectively, the first valve 305 being proximate to a first end of the first pipeline 301 and the second valve 307 being proximate to a second end of the first pipeline 301. The third valve 309 and the fourth valve 311 are both disposed on the second pipeline 302; also, a third valve 309 and a fourth valve 311 are located on opposite sides of the second communication location 34, respectively, the third valve 309 being proximate the first end of the second line 302 and the fourth valve 311 being proximate the second end of the second line 302.
Among them, a part of the first pipeline 301 between the first communication position 33 and the first tank 100, a part of the second pipeline 302 between the second communication position 34 and the second tank 200, and the third pipeline 303 serve as a first pipeline group communicating the first tank 100 and the second tank 200. The first valve 305, the fourth valve 311 and the power pump 31 are disposed on the first pipeline set.
When the first valve 305 and the fourth valve 311 are opened and the second valve 307 and the third valve 309 are closed, the liquid in the first tank 100 enters the third line 303 via the first end of the first line 301, the first valve 305 and the first communication position 33, and the liquid in the third line 303 enters the second tank 200 via the second communication position 34, the fourth valve 311 and the second end of the second line 302.
A part of the first pipeline 301 between the first communication position 33 and the second tank 200, a part of the second pipeline 302 between the second communication position 34 and the first tank 100, and the third pipeline 303 serve as a second pipeline group communicating the first tank 100 and the second tank 200. The second valve 307, the third valve 309, and the power pump 31 are provided in the second line group.
When the second valve 307 and the third valve 309 are opened and the first valve 305 and the fourth valve 311 are closed, the liquid in the second tank 200 enters the third line 303 via the second end of the first line 301, the second valve 307 and the first communication position 33, and the liquid in the third line 303 enters the first tank 100 via the second communication position 34, the third valve 309 and the first end of the second line 302.
By adopting the structure, the liquid in the first tank body 100 is conveyed into the second tank body 200, or the liquid in the second tank body 200 is conveyed into the first tank body 100, and the flow direction of the liquid in the third pipeline 303 is not changed, so that a conventional pump is adopted, and frequent forward and reverse rotation is not needed.
The specific process of transporting the multiphase flow mixture is as follows.
The valve on the reversing mechanism and the power pump 31 are opened to pump the liquid in the first tank 100 into the second tank 200. The volume of the liquid in the first tank 100 is reduced, so that a vacuum suction cavity is formed in the first tank, and the multiphase flow mixture to be conveyed is sucked into the first tank 100. As the liquid in the first tank 100 is transferred into the second tank 200, the volume of the liquid in the second tank 200 is correspondingly increased, so that a compression discharge cavity is formed in the second tank 200, and the gas at the upper part in the second tank 200 enters the discharge pipeline 5 through the second discharge hole and the second discharge pipeline 203, thereby realizing the transfer of pure gas.
When only gas is delivered, the pumping of liquid into the second tank 200 may be stopped when the liquid level in the second tank 200 rises to the first predetermined position. If the liquid level in the first tank 100 has dropped to the second preset position before the liquid level in the second tank 200 rises to the first preset position, the liquid pumping into the second tank 200 is also stopped, so as to prevent the gas in the first tank 100 from entering the reversing mechanism to cause the idling of the power pump 31 or other faults.
When the liquid level in the second tank 200 rises to a first preset position, or when the liquid level in the first tank 100 falls to a second preset position, the flow direction of the liquid in the reversing mechanism is changed, so that the liquid in the second tank 200 is pumped into the first tank 100. Similarly, when the liquid in the second tank 200 is pumped into the first tank 100, a vacuum suction chamber can be formed in the second tank 200, and the multiphase flow mixture to be delivered is sucked into the second tank 200; meanwhile, a compression discharge cavity is formed in the first tank 100, and the multiphase flow mixture in the first tank 100 is discharged from the first tank 100 to be conveyed to a next process, and the specific operation process is not described herein again.
When the liquid level in the second tank 200 drops to a third preset position or the liquid level in the first tank 100 rises to a fourth preset position, the flow direction of the liquid in the reversing mechanism is switched again, the liquid in the first tank 100 is conveyed into the second tank 200 through the reversing mechanism, and the multiphase flow mixture to be conveyed is sucked into the first tank 100 again. The operations are repeated, so that the multiphase flow mixture enters one of the first tank 100 and the second tank 200, and the gas is discharged from the other of the first tank 100 and the second tank 200, thereby realizing the transportation of the pure gas.
It can be understood that when it is required to simultaneously convey the materials containing gas and liquid, after the gas at the upper part in the second tank 200 is conveyed to the discharge line 5, the liquid in the first tank 100 can be continuously pumped into the second tank 200, so that the liquid in the second tank 200 also enters the discharge line 5 through the second discharge hole, and then the mixed conveyance of the gas and the liquid can be realized.
At this time, when the liquid level in the first tank 100 drops to the second predetermined position, the flow direction of the liquid in the reversing mechanism can be changed, and the liquid is pumped from the second tank 200 into the first tank 100. Similarly, after the gas in the first tank 100 exits the first tank 100 and enters the discharge line 5, the liquid in the second tank 200 continues to be pumped into the first tank 100, so that the liquid in the first tank 100 also enters the discharge line 5 through the first discharge hole and the first discharge line 103, and mixed transportation of the gas and the liquid is realized.
In some embodiments, the step of activating the reversing mechanism and adjusting the flow rate of the liquid in the reversing mechanism comprises:
controlling a power pump in the reversing mechanism to start, wherein the power pump is connected with the first tank body 100 and the second tank body 200 through a first pipeline group and a second pipeline group;
detecting the states to be opened and closed of the first pipeline set and the second pipeline set;
controlling to open a valve to be opened in the first pipeline group or the second pipeline group and controlling to close the valve to be closed in the first pipeline group or the second pipeline group;
adjusting the opening speed of the valve to be opened and adjusting the closing speed of the valve to be closed, and/or controlling the pumping speed of the power pump.
When the liquid in the first tank 100 is conveyed to the second tank 200, or the liquid in the second tank 200 is conveyed to the first tank 100, the liquid is regulated and controlled through the reversing mechanism. The following description will be given taking as an example a process of transferring the liquid in the first tank 100 to the second tank 200.
And detecting the opening and closing states of the four valves in the reversing mechanism, opening the first valve 305 and the fourth valve 311 on the first pipeline group, closing the second valve 307 and the third valve 309 on the second pipeline group, starting the power pump 31, and pumping the liquid in the first tank 100 into the second tank 200 through the first pipeline group.
When the corresponding valve is opened or closed, the opening or closing speed of the corresponding valve can be regulated and controlled by regulating and controlling the rotating speed of the driving mechanism; the pumping speed of the first tank 100 into the second tank 200 can be adjusted by adjusting the rotation speed of the motor driving the power pump 31 to rotate. In the actual reversing process, the opening and closing speed of the valve can be adjusted, and/or the pumping speed of the power pump 31 can be adjusted at the same time, so that the flow rate of liquid in the reversing mechanism can be adjusted, and the liquid impact phenomenon in the reversing process can be relieved or avoided.
Specifically, on reversal, the closing speeds of the second 307 and third valves 309 are adjusted down; during this process, the power pump 31 may be shut down to avoid idle running. When the first valve 305 and the fourth valve 311 are opened, the opening speeds of the first valve 305 and the fourth valve 311 are reduced, so that the two valves are opened slowly; in the process, the power pump 31 can be started in real time, and the liquid in the first tank 100 is pumped into the second tank 200 when the power pump is started.
When the second 307 valve and the third valve 309 are closed slowly, or when the first 305 valve and the fourth 311 valve are opened slowly, the rotation speed of the power pump 31 can be reduced to reduce the pumping speed of the power pump 31 for pumping the liquid when the power pump 31 is started. The rotating speed of a driving mechanism for driving the valve to open and close can be specifically reduced, so that the purpose of reducing the opening and closing speed of the valve is achieved. Similarly, the purpose of reducing the pumping speed of the power pump 31 can be achieved by reducing the rotation speed of the motor driving the power pump 31 to operate. It can be understood that, after the state of the first tank 100 transferring the liquid into the second tank 200 is stabilized, the first valve 305 and the fourth valve 311 in the reversing mechanism are normally in the fully open state, and at this time, the pumping speed of the power pump 31 is also returned to the normal state, which is suitable for the requirement of pumping the liquid between the two tanks.
Further, the pumping speed of the power pump 31 can be adaptively controlled according to the opening or closing speed of each valve in the reversing mechanism. Specifically, during the reversing process, when the first valve 305 and the fourth valve 311 are opened slowly, the opening speed of the two valves is low, the flow rate of the liquid in the first pipeline group is low, and at this time, the pumping speed of the power pump 31 can be adjusted accordingly according to the opening speed of the two valves. For example, a first preset ratio of the opening speed or the closing speed of the valve to the rotation speed of the motor driving the power pump 31 may be preset, and when the first valve 305 and the fourth valve 311 are opened (normally, the opening speeds of the two valves are the same), the rotation speed of the motor driving the power pump 31 to move may be adjusted according to the product of the opening speeds of the two valves and the first preset ratio or other models about the two, so as to adjust the pumping speed of the liquid in the reversing mechanism. By adopting the adjusting mode, the pumping speed of the power pump is adapted to the opening or closing speed of the valve, so that the idling of the power pump 31 can be avoided, and the backflow phenomenon in the reversing process can be avoided.
Similarly, when the liquid in the second tank 200 is pumped into the first tank 100, the first valve 305 and the fourth valve 311 on the first line set are slowly closed, and the power pump 31 is stopped; the second 307 valve and the third valve 309 on the second pipeline set are opened slowly, and the power pump 31 is started. The specific implementation process is not described herein again.
The flow direction of the liquid in the reversing mechanism can be realized by opening or closing corresponding valves on different pipeline groups; by adjusting the opening and closing speed of the valve and/or the pumping speed of the power pump, the liquid impact phenomenon in the reversing process can be effectively relieved or avoided.
In some embodiments, the step of controlling the pumping speed of the power pump comprises:
acquiring the flow of the multiphase flow mixture to be conveyed into the first tank body or the second tank body;
regulating and controlling the speed of the power pump for pumping the liquid according to the preset ratio between the flow of the multiphase flow mixture to be conveyed into the first tank body or the second tank body and the flow of the liquid in the reversing mechanism;
preferably, the power pump pumps the liquid at a flow rate equal to or greater than the flow rate of the multiphase flow mixture to be delivered into the first or second tank.
The following description will be made by taking the process of pumping the liquid in the first tank 100 into the second tank 200 as an example. At this time, the multiphase flow mixture to be transferred is sucked into the first tank 100, and the gas, liquid, or gas-liquid mixture is discharged from the second tank 200 into a discharge line to be transferred to a next process.
After the multiphase flow mixture enters the first tank, the gas and liquid are separated in the first tank 100. When the flow rates of the multiphase flow mixture entering the first tank 100 are different and the flow rate of the liquid pumped by the reversing mechanism is unchanged, the air pressure in the first tank 100 fluctuates greatly, which is not favorable for stabilizing the air pressure in the first tank. When the pressure fluctuation in the first tank 100 is large, the efficiency of the multiphase flow mixture entering the first tank 100 is affected.
At this time, when the multiphase flow mixture to be delivered is sucked into the first tank 100, the flow rate of the multiphase flow mixture into the first tank 100 is obtained. According to the flow rate of the multiphase flow mixture entering the first tank 100, the pumping speed of the first tank 100 to the second tank 200 is correspondingly adjusted, so that the stability of the air pressure in the first tank 100 is maintained.
Specifically, when the flow rate of the multiphase flow mixture entering the first tank 100 is relatively high, the pumping speed of the power pump 31 can be correspondingly increased, so as to avoid that the gas pressure in the first tank 100 rises too fast to affect the efficiency of the first tank 100 for sucking the multiphase flow mixture. When the flow rate of the multiphase flow mixture entering the first tank 100 is too small, the pumping speed of the power pump 31 can be correspondingly reduced, so that the situation that the air pressure in the first tank 100 drops too fast and the flow direction of the liquid in the reversing mechanism needs to be frequently switched is avoided, and the power pump 31 is further prevented from being frequently started and stopped.
Further, a second preset proportion value of the flow rate of the multiphase flow mixture entering the first tank 100 and the flow rate of the liquid in the reversing mechanism can be preset. The rotation speed of the motor driving the power pump 31 to operate can be adjusted according to the product of the flow rate of the multiphase flow mixture entering the first tank 100 and the second preset proportion value, or other models related to the two, so as to adjust the pumping speed of the power pump 31, so that the flow rate of the liquid in the reversing mechanism is adapted to the flow rate of the multiphase flow mixture entering the first tank 100, so as to keep the air pressure in the first tank 100 stable.
When the multiphase flow mixture to be delivered is sucked into the second tank 200, the specific adjustment manner is similar to the adjustment manner when the multiphase flow mixture to be delivered is sucked into the first tank 100, and the detailed description is omitted here.
The pumping speed of the power pump 31 is correspondingly adjusted through the flow rate of the multiphase flow mixture to be conveyed entering the first tank 100 or the second tank 200, and further the pumping speed of the liquid in the reversing mechanism is adjusted, so that the flow rate of the liquid in the reversing mechanism is adaptive to the flow rate of the multiphase flow mixture entering the corresponding tank, the stability of the air pressure in the corresponding tank can be maintained, the conveying efficiency is improved, or the start-stop interval time of the power pump is prolonged.
In some embodiments, the step of controlling the pumping speed of the power pump 31 includes:
acquiring air pressure values in the first tank 100 and the second tank 200;
detecting that the multiphase flow mixture to be conveyed is conveyed into the first tank 100 or the second tank 200;
if the multiphase flow mixture to be conveyed is conveyed into the first tank 100, acquiring the difference value between the air pressure value in the second tank 200 and the air pressure value in the first tank 100;
judging whether the difference value is lower than a preset threshold value or not;
and if the difference value is lower than the preset threshold value, increasing the speed of the power pump for pumping the liquid.
During the transportation of the multiphase flow mixture, the multiphase flow mixture enters into any one of the first tank 100 and the second tank 200, and the gas and the liquid are separated. In the following, the multiphase flow mixture to be transported enters the first tank 100, and the liquid in the first tank 100 is pumped into the second tank 200 by the reversing mechanism.
The two tank bodies have certain air pressure, the air pressure values in the two tank bodies are respectively obtained, and the difference value between the air pressure in the second tank body 200 and the air pressure in the first tank body 100 is obtained. The air pressure difference is compared with a preset air pressure preset threshold value.
If the pressure difference between the two tanks is small, or even negative, the pressure in the first tank 100 is too high, which may affect the efficiency of the multiphase flow mixture to be transported entering the first tank 100. Meanwhile, the gas pressure in the second tank 200 is too small to facilitate the discharge of the gas, liquid, or gas-liquid mixture in the second tank 200, which may reduce the discharge efficiency of the gas, liquid, or gas-liquid mixture in the second tank 200.
By increasing the pumping speed of the power pump to pump the liquid, the rising speed of the liquid in the second tank 200 can be increased, the air pressure in the first tank 100 can be reduced, and the conveying efficiency can be improved.
In some embodiments, there is also provided a multiphase flow commingling device, comprising: the device comprises a first tank body 100, a second tank body 200, a reversing mechanism and a control mechanism;

The power pump 31 and the valve are provided on the communication line 32. The specific structure of the reversing mechanism can be in various forms, such as the structure that four valves are arranged according to the above description; for another example, only one direction changing valve may be provided. When a valve is arranged, the corresponding valve is arranged for driving the valve to act so as to control the opening and closing state and the opening and closing speed of the valve.
