Abstract
The utility model discloses an automatic liquid draining device of a gas-liquid separator. The automatic liquid draining device is designed for improving the running reliability of devices and implementing unattended management. The automatic liquid draining device is characterized in that the gas-liquid separator is communicated with a compressor via a natural gas pipeline, the compressor is respectively communicated with a first liquid storage tank and a second liquid storage tank via natural gas pipelines and a second electric three-way valve, and the first liquid storage tank and the second liquid storage tank are provided with external liquid monitoring devices; both the first liquid storage tank and the second liquid storage tank are communicated with the liquid-gas separator via liquid draining pipelines and first electric three-way valves and are connected with a gas-liquid mixed delivery pipeline and an external delivery port by a first check valve and a second check valve respectively. The automatic liquid draining device has the advantages that produced water separated by the gas-liquid separator can be forcedly drained into a gas delivery pipeline by the aid of pressurized natural gas, so that the gas and the liquid can be delivered in a mixed manner; delivery pumps can be omitted, accordingly, movable devices can be reduced, energy consumption can be decreased, the running reliability of the devices can be improved, and unattended management can be implemented.
Description
Technical field
The utility model relates to a kind of gas-liquid separator automatic draining device, belongs to petroleum gas gas-liquid separator technical field.
Background technique
In the process progressively reducing at natural gas well recovery pressure, supercharging exploitation is the important technical that improves gas field recovery rate and individual well accumulative total gas production.The compressor that supercharging is used requires strictly the impurity of rock gas and water content, otherwise can damage compressor, affects it and normally moves.Therefore, gas-liquid separator should be set before compressor, to meet the supercharging requirement of compressor.
Carrying out rock gas gas, liquid when mixed defeated, generally with water transport pump, the recovered water separating from gas-liquid separator is entered to the natural gas line supercharging.Water transport pump is moving equipment, and maintenance and the maintenance workload of easily damaged parts are large; Separator discharge opeing is unbalanced, and the frequent start-stop of pump, easily causes fault, and impact is normally produced; Lowered in field environment, the power of pump generally derives from the gas driven machine of compressor, and the design of gas driven machine need be considered the load of pump, and pump is in periodic running, is unfavorable for the maximization of driving machine efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of gas-liquid separator automatic draining device, to improve equipment operational reliability, realizes unmanned management.
Concrete technology contents of the present utility model is as follows:
The gas-liquid separator of this automatic draining device is communicated with compressor by natural gas line, and compressor is communicated with respectively first and second liquid container of peripheral hardware level monitoring device by natural gas line and the second electric T-shaped valve; First and second liquid container is all communicated with gas-liquid separator by tapping line and the first electric T-shaped valve, and by first and second safety check, connects gas-liquid delivery pipeline and outer defeated interface respectively.
The rock gas of the recovered water that this automatic draining device can separate gas-liquid separator after by supercharging enters gas pipeline by force, thereby realizes gas-liquid delivery.This device can be cancelled transfer pump, reduces moving equipment, reduces energy consumption, improves equipment operational reliability, realizes unmanned management.
Accompanying drawing explanation
Fig. 1 is gas-liquid separator automatic draining device schematic diagram.
Embodiment
Embodiment:
With reference to Fig. 1, embodiment of the present utility model is further illustrated:
This automatic draining device comprises separator import 1, gas-liquid separator 2, natural gas line 3, compressor 4, tapping line 5, first and second electric T-shaped valve 6, first and second liquid container 7, first and second safety check 8, gas-liquid delivery pipeline 9 and outer defeated interface 10:
Gas-liquid separator 2 is communicated with compressor 4 by natural gas line 3, and compressor 4 is communicated with respectively first and second liquid container 7 of peripheral hardware level monitoring device by natural gas line 3 and the second electric T-shaped valve 6; First and second liquid container 7 is all communicated with gas-liquid separator 2 by tapping line 5 and the first electric T-shaped valve 6, and by first and second safety check 8, connects gas-liquid delivery pipeline 9 and outer defeated interface 10 respectively.
The size of gas-liquid separator 2 and separating technology will grade according to the treating capacity of separator, separation accuracy and gas group comprehensive definite.The power of compressor 4, type of compressor (screw type, reciprocating, centrifugal etc.), driving mode (gas driven, electric drive etc.) will require comprehensively to determine according to gas collection technique, supercharging tolerance and inlet and outlet pressure.First and second electric T-shaped valve 6 is equipped with an import and two outlets, and import can be communicated with any one outlet, the situation that there will not be three mouthfuls of connections and two outlets to be communicated with.The volume of first and second liquid container 7 is determined according to the extraction water yield.First and second safety check 8 is for stoping rock gas and the recovered water of gas-liquid delivery pipeline 9 to be back in first and second liquid container 7.Level monitoring device has transporting function, with first and second electric T-shaped valve 6 interlocks, the mutual transhipment row of automatic controller liquid storage and discharge opeing.
The working principle of this gas-liquid separator automatic draining device is as follows;
Rock gas enters gas-liquid separator 2 from separator import 1 and carries out gas-liquid separation, and isolated natural gas via natural gas line 3 enters compressor 4 superchargings, and the natural gas via natural gas line 3 after supercharging enters the second electric T-shaped valve 6.Suppose first and second liquid container 7 now state in liquid storage and discharge opeing respectively, the second 6 of electric T-shaped valves switch to the natural gas line 3 that leads to the second liquid container 7, make rock gas enter the second liquid container 7, the recovered water storing in tank is entered to gas-liquid delivery pipeline 9 through the second safety check Final 8 row, and transport to downstream stations field by outer defeated interface 10; The first electric T-shaped valve 6 switches to the tapping line 5 that leads to the first liquid container 7, and the isolated recovered water of gas-liquid separator 2 is entered to the interior storage of the first liquid container 7.Recovered water liquid level in the first liquid container 7 is during higher than setting value, and the first electric T-shaped valve 6 switches to the tapping line 5 that leads to the second liquid container 7, and isolated recovered water is entered to the second liquid container 7; Now, the second electric T-shaped valve 6 automatically switches to the natural gas line 3 that leads to the first liquid container 7, makes rock gas enter the first liquid container 7, realizes automatic drain.
