Description

Technical Field

[0001] The utility model relates to the field of gas-liquid separation devices, in particular to a gas-liquid mixed transmission separation device. Background Art

[0002] At present, with the exploitation of natural gas and oil fields, the wellhead pressure is getting lower and lower. At the same time, with the increase in bottom hole liquid production, most gas wells can no longer meet the normal gravity production. There is an urgent need to use a large number of natural gas compressor units at the well site to carry out various operations such as pressurization, gas lift, and negative pressure mining.

[0003] During the operation, on the one hand, a large amount of hazardous waste water such as flowback fluid from gas wells and condensate fluid and lubricating oil from various levels of compressors will be generated to maintain the continuous and safe operation of the boosted mining process route; on the other hand, due to the wide and scattered distribution of gas wells, short boosted operation cycle, harsh site conditions, serious lack of available resources and facilities, and increasingly stringent requirements for well site environmental protection management, the discharge of wastewater from well sites to cause environmental pollution is no longer allowed.

[0004] Regarding the above-mentioned related technologies, due to the imperfect existing well site sewage treatment measures, the traditional well site hazardous waste treatment adopts large-volume storage and transportation or sewage booster pumps, which not only requires a lot of new equipment and is not conducive to relocation, but also has a high sewage pump failure rate, difficult transportation, and high treatment costs. Utility Model Content

[0005] In order to improve the efficiency and safety of gas-liquid separation, the utility model provides a gas-liquid mixed transmission separation device.

[0006] The utility model provides a gas-liquid mixed transmission and separation device, which adopts the following technical solutions:

[0007] A gas-liquid mixed transmission and separation device comprises a main body, an input mechanism, a separation mechanism, and an output mechanism. The main body comprises a first cylinder, a second cylinder, and a separation plate. The first cylinder and the second cylinder are connected to each other. The separation plate is disposed between the first cylinder and the second cylinder. The output end of the input mechanism is connected to the input end of the first cylinder.

[0008] The separation mechanism includes a gas-liquid separator and a flow guide pipe, wherein the gas-liquid separator is arranged in the first cylinder, the flow guide pipe is arranged at the outer end of the main body, the inlet end of the flow guide pipe is connected to the first cylinder, and the outlet end of the flow guide pipe is connected to the second cylinder;

[0009] The output mechanism includes an output pipeline and a compressor. The output pipeline includes a first output pipe, a second output pipe, a third output pipe, and an output main pipe. The input end of the first output pipe is connected to the output end of the first cylinder. The output end of the first output pipe is connected to the input end of the second output pipe and the input end of the output main pipe. The output end of the second output pipe is connected to the input end of the second cylinder. The input end of the third output pipe is connected to the bottom end of the second cylinder. The output end of the third output pipe is connected to the output main pipe.

[0010] The output main pipe is provided with a first valve body, the second output pipe is provided with a second valve body, and the third output pipe is provided with a third valve body.

[0011] By adopting the above technical solution, when natural gas needs to be transported as a mixture of gas and liquid, the gas and liquid first enter the first cylinder through the input mechanism. Then, water in the natural gas is separated by the action of the gas-liquid separator, and the water then falls to the bottom of the first cylinder and accumulates. The clean gas after separation is discharged from the first cylinder through the first output pipe. The water accumulated at the bottom of the first cylinder then enters the second cylinder through the guide pipe for collection. The clean gas is then pressurized by the compressor and enters the output main pipe for transportation. When the water in the second cylinder accumulates to a certain level, the first valve body is controlled to close, the second valve body and the third valve body are opened, the gas is pressurized by the compressor, and then the gas is pumped into the second cylinder through the second output pipe. The water at the bottom of the second cylinder is discharged into the output main pipe through the third output pipe, and the waste water in the second cylinder is discharged. This achieves the simultaneous transportation of gas and liquid, reduces the layout cost of the device, and improves the transportation efficiency. The waste water can be discharged centrally in the pipeline, reducing the possibility of waste water leakage and improving the safety of the device.

[0012] Optionally, the separation mechanism further includes a float valve, and the float valve is arranged at the inlet end of the guide tube.

[0013] By adopting the above technical solution, the device can control the discharge of liquid in the first cylinder through the float valve. When the liquid in the first cylinder is less, the float valve is closed, so that a stable air pressure can be maintained in the first cylinder, reducing the impact of unstable air pressure on the gas-liquid separation effect; after the liquid at the bottom end of the first cylinder accumulates to a certain level, the float valve opens, allowing the liquid to enter the second cylinder.

[0014] Optionally, the separation mechanism further includes a one-way valve, which is arranged at the outlet end of the flow guide tube.

[0015] By adopting the above technical solution, the possibility of gas flowing back into the first cylinder through the guide tube is reduced during the liquid discharge process of the second cylinder, so that the liquid discharge in the second cylinder is more stable.

[0016] Optionally, the separation mechanism further includes a balancing assembly, which includes a balancing pipe and a balancing valve, one end of the balancing pipe is connected to the first cylinder, and the other end of the balancing pipe is connected to the second cylinder.

[0017] By adopting the above technical solution, the balancing valve is in an open state when gas-liquid separation is performed, so that the air pressure between the first cylinder and the second cylinder can be stabilized, and the liquid in the first cylinder can stably enter the second cylinder, reducing the possibility of excessive accumulation of liquid in the first cylinder; at the same time, during the liquid discharge process, the balancing valve is closed, so that the air pressure between the first cylinder and the second cylinder does not affect each other; at the same time, after the liquid discharge process is completed, the remaining gas in the second cylinder is still in a high-pressure state, and the balancing valve is controlled to open slowly, so that the remaining gas in the second cylinder slowly enters the first cylinder, thereby improving the safety of the device and the recovery efficiency of the remaining gas. At the same time, the remaining gas re-entering the first cylinder can again separate the liquid mixed in the second cylinder through the gas-liquid separator, further improving the gas recovery effect.

[0018] Optionally, the separation mechanism further includes a wire mesh demister, which is disposed in the first cylinder and is located at the top end of the first cylinder.

[0019] By adopting the above technical solution, when performing gas-liquid separation, the gas separated by the gas-liquid separator may still be mixed with fine liquid, and then pass through the more detailed separation action of the wire mesh demister, so that the degree of separation of liquid in the gas is higher, further improving the gas-liquid separation effect.

[0020] Optionally, the separation mechanism further includes a liquid level sensor and a pressure sensor, wherein the liquid level sensor is disposed in the second cylinder, and the pressure sensor is disposed in the first cylinder.

[0021] By adopting the above technical solution, during the process of gas-liquid mixed transmission, the waste liquid content in the second cylinder is detected by the liquid level sensor, so that it is possible to choose whether to perform the drainage process according to the amount of waste water, thereby reducing the need for drainage by regular drainage, reducing unnecessary drainage times, and improving production efficiency; the gas pressure in the first cylinder is detected by the pressure sensor to control the rate of gas and liquid input in the input mechanism, reducing the possibility of excessive or low gas and liquid levels in the first cylinder, and improving safety.

[0022] Optionally, the separation mechanism further includes a detection sensor, which is disposed in the first cylinder and close to the input end of the first output tube.

[0023] By adopting the above technical solution, during the gas-liquid separation process, the detection sensor detects the moisture content in the gas about to enter the first output pipe. If the moisture content meets the standard, the air intake of the input mechanism will not be changed. If the moisture content does not meet the standard, the air intake of the input mechanism will be adjusted, so that the output gas can be more standardized. At the same time, after the drainage step is completed, if the gas and liquid re-entering the first cylinder from the second cylinder do not meet the standard, the gas can be allowed to re-enter the output mechanism and the first cylinder to participate in another gas-liquid separation, thereby improving the gas-liquid separation effect.

[0024] Optionally, the input mechanism includes an input pipe and an input valve, the output end of the input pipe is communicated with the input end of the first cylinder, the input valve is provided on the input pipe, and a sensor unit is provided on the input pipe.

[0025] By adopting the above technical solution, when feeding is required, the gas-liquid mixture enters the first cylinder through the input pipe, and the feed amount is controlled by the input valve. At the same time, the pressure and temperature of the material in the input pipe are detected by the sensor unit to monitor whether the feed is within the normal range.

[0026] Optionally, a drain pipe is provided at the bottom end of the second cylinder, an input end of the drain pipe is communicated with the second cylinder, and a fourth valve body is provided on the drain pipe.

[0027] By adopting the above technical solution, when the main body needs to be cleaned or discharged, the fourth valve body is manually opened to allow the waste liquid in the second cylinder to be discharged through the drain pipe, thereby realizing manual discharge. When the output mechanism is blocked, in an emergency or shut down for maintenance, manual discharge can be performed to drain the waste liquid in time and enable the device to operate normally.

[0028] Optionally, a sewage pipe is further connected to the second cylinder, and the sewage pipe is communicated with the upper end of the second cylinder.

[0029] By adopting the above technical solution, it is possible to connect other devices through the sewage pipe, collect wastewater into the second cylinder, and realize centralized collection and discharge of wastewater.

[0030] In summary, the present invention has at least one of the following beneficial technical effects:

[0031] 1. By setting up a separation mechanism, the gas-liquid separation of the material can be achieved stably, so that the gas pressure in the first cylinder can be maintained stable, reducing the impact of unstable air pressure on the gas-liquid separation effect; when the liquid at the bottom of the first cylinder accumulates to a certain level, the float valve opens to allow the liquid to enter the second cylinder.

[0032] 2. By setting a balancing component, the balancing valve is in an open state when gas-liquid separation is performed, so that the air pressure between the first cylinder and the second cylinder can be stabilized, and the liquid in the first cylinder can stably enter the second cylinder, reducing the possibility of excessive accumulation of liquid in the first cylinder; at the same time, during the liquid discharge process, the balancing valve is closed, so that the air pressure between the first cylinder and the second cylinder does not affect each other; at the same time, after the liquid discharge process is completed, the remaining gas in the second cylinder is still in a high-pressure state, and the balancing valve is controlled to open slowly, so that the remaining gas in the second cylinder slowly enters the first cylinder, thereby improving the safety of the device and the recovery efficiency of the remaining gas. At the same time, the remaining gas re-entering the first cylinder can again separate the liquid mixed in the second cylinder through the gas-liquid separator, further improving the gas recovery effect.

[0033] 3. By setting up a detection sensor, during the gas-liquid separation process, the detection sensor detects the moisture content in the gas about to enter the first output pipe. If it meets the standard, the air intake of the input mechanism will not be changed. If it does not meet the standard, the air intake of the input mechanism will be adjusted, so that the output gas can be more standardized; at the same time, after the drainage step is completed, if the gas and liquid re-entering the first cylinder from the second cylinder do not meet the standard, the gas can be allowed to enter the output mechanism and the first cylinder again, and participate in another gas-liquid separation, thereby improving the gas-liquid separation effect.

DETAILED DESCRIPTION

[0038] The following combination Figures 1 to 3 The utility model is described in further detail.

[0039] The present invention discloses a gas-liquid mixed transmission and separation device. Figure 1 A gas-liquid mixed transmission and separation device mainly includes a main body 100, an input mechanism 200, a separation mechanism 300 and an output mechanism 400. The main body 100 includes a first cylinder 110, a second cylinder 120 and an isolation plate 130. The first cylinder 110 and the second cylinder 120 are connected to each other, and the isolation plate 130 is arranged between the first cylinder 110 and the second cylinder 120.

[0040] The input mechanism 200 includes an input pipe 210 and an input valve 220. The output end of the input pipe 210 is connected to the input end of the first cylinder 110. The input valve 220 is provided on the input pipe 210. The sensor unit 230 is provided on the input pipe 210.

[0041] The separation mechanism 300 includes a gas-liquid separator 310, a flow guide tube 320, a float valve 330, a one-way valve 340, and a wire mesh demister 360. The gas-liquid separator 310 is disposed within the first cylinder 110. The flow guide tube 320 is disposed at the outer end of the main body 100. The inlet end of the flow guide tube 320 is in communication with the first cylinder 110, and the outlet end of the flow guide tube 320 is in communication with the second cylinder 120. The float valve 330 is disposed at the inlet end of the flow guide tube 320, the one-way valve 340 is disposed at the outlet end of the flow guide tube 320, and the wire mesh demister 360 is disposed within the first cylinder 110 and is located at the top end of the first cylinder 110.

[0042] The output mechanism 400 includes an output pipeline 410 and a compressor 420. The output pipeline 410 includes a first output pipe 411, a second output pipe 412, a third output pipe 413, and an output main pipe 414. The input end of the first output pipe 411 is connected to the output end of the first cylinder 110, the output end of the first output pipe 411 is connected to the input end of the second output pipe 412 and the input end of the output main pipe 414, the output end of the second output pipe 412 is connected to the input end of the second cylinder 120, the input end of the third output pipe 413 is connected to the bottom end of the second cylinder 120, and the output end of the third output pipe 413 is connected to the output main pipe 414.

[0043] A first valve body 415 is provided on the output main pipe 414 , a second valve body 416 is provided on the second output pipe 412 , and a third valve body 417 is provided on the third output pipe 413 .

[0044] When it is necessary to transport the natural gas as a mixture of gas and liquid, the gas and liquid first enter the first cylinder 110 through the input mechanism 200, and then the water in the natural gas is separated under the action of the gas-liquid separator 310, and then the water falls to the bottom of the first cylinder 110 and gathers. The clean gas after separation is discharged from the first cylinder 110 through the first output pipe 411, and then the water gathered at the bottom of the first cylinder 110 enters the second cylinder 120 through the guide pipe 320 for collection; then the clean gas is pressurized by the compressor 420 and enters the output main pipe 414 for transportation; when the water in the second cylinder 120 accumulates to a certain level, the first valve body 415 is controlled to be closed, the second valve body 416 and the third valve body 417 are opened, and the gas is pressurized by the compressor 420, and then the gas is pumped into the second cylinder 120 through the second output pipe 412, and the water at the bottom of the second cylinder 120 is discharged through the third valve body 417. The output pipe 413 discharges into the output main pipe 414, draining the wastewater in the second cylinder 120, thereby realizing the simultaneous transportation of gas and liquid, reducing the layout cost of the device and improving the transportation efficiency; when the liquid in the first cylinder 110 is less, the float valve 330 is closed, so that the first cylinder 110 can maintain a stable air pressure, reducing the impact of unstable air pressure on the gas-liquid separation effect; after the liquid at the bottom end of the first cylinder 110 accumulates to a certain level, the float valve 330 is opened, allowing the liquid to enter the second cylinder 120; through the one-way valve 340, when the second cylinder 120 is drained, the possibility of gas flowing back into the first cylinder 110 through the guide pipe 320 is reduced, making the liquid discharge in the second cylinder 120 more stable; wastewater can be discharged in a centralized manner in the pipeline, reducing the possibility of wastewater leakage and improving the safety of the device.

[0045] Furthermore, in some embodiments, the separation mechanism 300 also includes a balancing assembly 350 , which includes a balancing pipe 351 and a balancing valve 352 . One end of the balancing pipe 351 is connected to the first cylinder 110 , and the other end of the balancing pipe 351 is connected to the second cylinder 120 .

[0046] When gas-liquid separation is being performed, the balancing valve 352 is in an open state, so that the air pressure between the first cylinder 110 and the second cylinder 120 can be stabilized, and the liquid in the first cylinder 110 can stably enter the second cylinder 120, reducing the possibility of excessive accumulation of liquid in the first cylinder 110; at the same time, during the liquid discharge process, the balancing valve 352 is closed, so that the air pressure between the first cylinder 110 and the second cylinder 120 does not affect each other; at the same time, after the liquid discharge process is completed, the remaining gas in the second cylinder 120 is still in a high-pressure state. By controlling the balancing valve 352 to open slowly, the remaining gas in the second cylinder 120 slowly enters the first cylinder 110, thereby improving the safety of the device and the recovery efficiency of the remaining gas. At the same time, the remaining gas re-entering the first cylinder 110 can again separate the liquid mixed in the second cylinder 120 through the gas-liquid separator 310, further improving the gas recovery effect.

[0047] Furthermore, in some embodiments, the separation mechanism 300 further includes a liquid level sensor 370 and a pressure sensor 380 . The liquid level sensor 370 is disposed in the second cylinder 120 , and the pressure sensor 380 is disposed in the first cylinder 110 .

[0048] During the process of gas-liquid mixed transportation, the waste liquid content in the second cylinder 120 is detected by the liquid level sensor 370, so that it is possible to choose whether to perform the drainage process according to the amount of waste water, thereby reducing the need for drainage through regular drainage, reducing unnecessary drainage times, and improving production efficiency; the gas pressure in the first cylinder 110 is detected by the pressure sensor 380, and the rate of gas and liquid input in the control input mechanism 200 is controlled, thereby reducing the possibility of excessive or low gas and liquid in the first cylinder 110 and improving safety.

[0049] Furthermore, in some embodiments, the separation mechanism 300 further includes a detection sensor 390, which is disposed within the first cylinder 110 and is located near the input end of the first output pipe 411. During the gas-liquid separation process, the detection sensor 390 detects the moisture content in the gas about to enter the first output pipe 411. If the moisture content meets the standard, the air intake of the input mechanism 200 is not changed; if the moisture content does not meet the standard, the air intake of the input mechanism 200 is adjusted, thereby making the output gas more standardized. Furthermore, after the liquid discharge step is completed, if the gas and liquid re-entering the first cylinder 110 from the second cylinder 120 do not meet the standard, the gas can be allowed to re-enter the output mechanism 400 and then the first cylinder 110 to participate in another gas-liquid separation, thereby improving the gas-liquid separation effect.

[0050] Furthermore, in some embodiments, a drain pipe 510 is provided at the bottom end of the second cylinder 120 , an input end of the drain pipe 510 is communicated with the second cylinder 120 , and a fourth valve body 520 is provided on the drain pipe 510 .

[0051] When the main body 100 needs to be cleaned or discharged, the fourth valve body 520 is manually opened to allow the waste liquid in the second cylinder 120 to be discharged through the drain pipe 510, thereby realizing manual discharge. When the output mechanism 400 is blocked, in an emergency or shut down for maintenance, manual discharge can be performed to drain the waste liquid in time and enable the device to operate normally.

[0052] Furthermore, in some embodiments, a drain pipe 530 is connected to the second cylinder 120, and the drain pipe 530 is in communication with the upper end of the second cylinder 120. This enables connection of other devices through the drain pipe 530 to collect wastewater into the second cylinder 120, thereby achieving centralized collection and discharge of wastewater.

[0053] Furthermore, in some embodiments, the input mechanism 200 further includes a safety valve 240, two branch pipes 260, and a main pipe 250. One end of the two branch pipes 260 is connected to the main pipe 250 via a tee. One end of one branch pipe 260 is connected to the input pipe 210, and the other branch pipe 260 is connected to the second cylinder 120. Two safety valves 240 are provided, each of which is disposed on each branch pipe 260, with one branch pipe 260 corresponding to one safety valve 240. During operation of the device, if the pressure in the input pipe 210 or the second cylinder 120 exceeds the safety threshold of the safety valve 240, the safety valve 240 opens to discharge excess gas, thereby reducing the possibility of the pressure in the input pipe 210 or the second cylinder 120 exceeding the limit and causing danger.

[0054] The implementation principle of the gas-liquid mixed transmission and separation device in the embodiment of the utility model is:

[0055] The material is input into the first cylinder 110 through the input mechanism 200, and the gas-liquid separation is performed through the separation mechanism 300. Then, the separated gas is discharged by the output mechanism 400. Then, when the gas is not needed to be transported, the waste liquid in the second cylinder 120 is discharged again, thereby realizing the simultaneous transportation of gas and liquid, reducing the layout cost of the device and improving the transportation effect.

[0056] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
