Domain.
Background technology
In the natural gas station of oil and gas industry and petrochemical industry, unstripped gas typically all petroleum zone water, is satisfaction
The needs of downstream process（Such as be pressurized, manage it is defeated etc.）, yard will arrange gas-liquid separator, separate unstripped gas gas-liquid, and setting has
The emptying liquid-separation pot of emptying liquid-separation and recovered water flash distillation function.Before torch is accessed, emptying liquid-separation pot to be passed through divides emptying house steward
Liquid, take torch out of and form " fire rain " oil, water to avoid being vented, jeopardize yard safety during unstripped gas.In addition, will also be by dodging
Steam separator and separate recovered water, to reduce the discharge on the spot of solution gas, reduce environmental effect.
Fig. 1 is conventional gas-liquid separator 1 and the schematic diagram of double-cylinder type flash distillation point flow container 2, and raw natural gas Jing air inlets 3 enter
Enter separator 1 to be separated, after separation, down stream train, the liquid Jing leakage fluid drams 5 isolated and automatic drain are accessed in Jing gas outlets 4
Device 6 accesses the inlet 7 of flash distillation point flow container 2, and the liquid Jing leakage fluid drams 10 after flash distillation transport to downstream storage tank.The emptying of yard is total
Guan Laiqi Jing air inlets 8 enter flash distillation point flow container 2, and after point liquid, Jing gas outlets 9 are accessed and released flare.Separator in above-mentioned technique
1 and flash distillation be divided to flow container 2 for two equipment, invest higher, yard floor space is big, and the pipeline between equipment installs complicated, construction
Cycle is long.
The content of the invention
It is an object of the invention to provide a kind of separate flash distillation plant, which has gas-liquid separation, flash distillation and emptying liquid-separation etc.
Several functions, can reduce yard equipment, reduce investment, reduce and take up an area and shorten construction period.
The concrete technical scheme of the present invention is as follows：
This device is gas-liquid separation chamber and flash distillation point sap cavity by plugging separating；
Gas-liquid separation chamber is provided with disengagement chamber air inlet and disengagement chamber gas outlet, and gas-liquid separation chamber connects disengagement chamber liquid storage pipe,
Disengagement chamber liquid storage pipe is provided with disengagement chamber leakage fluid dram and disengagement chamber liquid storage pipe maintenance blind plate；
Flash distillation point sap cavity is provided with air inlet and the gas outlet that emptying house steward carrys out gas, and is communicated with dividing for disengagement chamber leakage fluid dram
Sap cavity inlet, flash distillation point sap cavity connection point sap cavity liquid storage pipe, a point sap cavity liquid storage pipe are provided with point sap cavity leakage fluid dram and point sap cavity storage
Liquid pipe overhauls blind plate.
The present invention integrates separation, flash distillation and point liquid function of typical separators and flash distillation point flow container, can reduce yard
Equipment is arranged, and reduces gas gathering station floor space, and reduction operation space is reduced equipment and installed and pipeline network construction, shortens construction period,
Construction investment is reduced, is easy to sledge dressization.
Description of the drawings
Fig. 1 is conventional gas station separator and flash distillation point flow container schematic diagram.
Fig. 2 is separation flash distillation plant structural representation.
Specific embodiment
Embodiments of the invention are further illustrated with reference to Fig. 2：
Embodiment：
The columnar inner chamber of this device is divided into gas-liquid separation chamber 11 and flash distillation point sap cavity 12 by the closure 18 of arc；
Gas-liquid separation chamber 11 is provided with disengagement chamber air inlet 13 and disengagement chamber gas outlet 14, and the connection of gas-liquid separation chamber 11 is positioned at which
The disengagement chamber liquid storage pipe 16 of lower section, disengagement chamber liquid storage pipe 16 are provided with disengagement chamber leakage fluid dram 15 and disengagement chamber liquid storage pipe maintenance blind plate
17；
Flash distillation point sap cavity 12 is provided with air inlet 20 and the gas outlet 21 that emptying house steward carrys out gas, and is communicated with disengagement chamber discharge opeing
Point sap cavity inlet 19 of mouth 15, point sap cavity liquid storage pipe 24 that the flash distillation point connection of sap cavity 12 is disposed below, divides sap cavity liquid storage pipe
24 are provided with point sap cavity leakage fluid dram 22 and point sap cavity liquid storage pipe maintenance blind plate 23.
The operation principle of this separation flash distillation plant is as follows：
The separated chamber air inlet 13 of unstripped gas enters the gas-liquid separation chamber 11 of this device, separates under 14 access of gas Jing gas outlets
Trip flow process, separating liquid are stored in disengagement chamber liquid storage pipe 16, and separated chamber leakage fluid dram 15 and point sap cavity inlet 19 enter this
The flash distillation of device point sap cavity 12.Separating liquid after flash distillation is stored in point sap cavity liquid storage pipe 24, and Jing point of sap cavity leakage fluid dram 22 is defeated
Toward downstream storage tank.The emptying house steward of yard carrys out gas Jing air inlets 20 into flash distillation point sap cavity 12, is connect by gas outlet 21 Jing after point liquid
Enter to release flare.
Gas-liquid separation chamber 11 and flash distillation point sap cavity 12 each possess independent liquid storage pipe, and gas-liquid separation chamber 11 can be according to process
Handling process and equipment are selected in medium and required precision, and flash distillation point sap cavity 12 can be selected according to emptying tolerance and flash distillation liquid measure and be set
It is standby.Disengagement chamber liquid storage pipe maintenance blind plate 17 and a point sap cavity liquid storage pipe maintenance blind plate 23 are set up for convenience of maintenance.
