Summary of the invention
The purpose of this utility model provides the vertical inward turning gas-liquid separator of a kind of foaming crude oil, it is mainly used in the gas-liquid separation of other liquid of the gas-liquid separation of oil field foaming crude oil or similar crude oil medium, accelerate the sinking speed of drop in the gas, improve gas-liquid separation efficient.This separator has the internal structure compactness, the separative efficiency height, and operating flexibility is big, wide accommodation, characteristics such as floor space is little, and production run is safe and reliable.
The utility model is achieved in that the vertical inward turning gas-liquid separator of a kind of foaming crude oil, comprise: vertical gas-liquid separator, be provided with former oil-in, gas outlet, oil, sand outlet, described vertical gas-liquid separator is divided into upper and lower two chambers by being provided with dividing plate with vertical gas-liquid separator; Described cyclone separator is arranged on bottom chamber, and wireway is communicated with cyclone separator and upper chamber, and vertical gas-liquid separator bottom chamber is led to tangential direction in former oil-in.
Be provided with mist eliminator between the wireway outlet of described upper cavity and the gas outlet, mist eliminator connects dividing plate to device and pushes up, and upper cavity is divided into left and right two Room, and the gas outlet is arranged on the top, right ventricle.
Described bottom chamber is established conduit and is passed the left chamber of dividing plate to upper cavity.
Be cylinder on the described cyclone hydraulic separators, be the assembly of circular cone tube down, be provided with 2 cyclone air inlets in its cylinder tangential direction, circular cone tube bottom is provided with bottom tube.
Described vertical gas-liquid separator bottom and bottom one side are provided with sand outlet and oil export.
The utility model adopts vertical gas-liquid separator and cyclone separator to carry out secondary separation, accelerate the sinking speed of drop in the gas, general force of gravity sedimentation can improve tens of times, improved gas-liquid separation efficient, this separator has compact conformation, occupation of land face is less, the separative efficiency height, and operating flexibility is big, wide accommodation, advantage such as production run is safe and reliable.

The specific embodiment:
Embodiment 1:
Its structure is as shown in Figure 1: the vertical inward turning gas-liquid separator of a kind of foaming crude oil, comprise: vertical gas-liquid separator 1, be provided with former oil-in 2, gas outlet 6, oil, sand outlet 11,10, described vertical gas-liquid separator 1 is divided into upper and lower two chambers by being provided with dividing plate 8 with vertical gas-liquid separator; Described cyclone separator 3 is arranged on bottom chamber, and wireway 5 is communicated with cyclone separator 3 and upper chamber, and vertical gas-liquid separator 1 bottom chamber is led to tangential direction in former oil-in 2.
Be provided with a mist eliminator 7 between wireway 5 outlets of described upper cavity and the gas outlet 6, mist eliminator 7 connects dividing plate 8 to the device top, and upper cavity is divided into left and right two Room, and gas outlet 6 is arranged on the top, right ventricle.
Described bottom chamber is established catheter 4 and is passed the left chamber of dividing plate 8 to upper cavity.
Be cylinder on the described cyclone separator 3, be the assembly of circular cone tube down, be provided with 2 movable flow device air inlets 9 in its cylinder tangential direction, circular cone tube bottom is provided with bottom tube.
Described vertical gas-liquid separator 1 bottom and bottom one side are provided with sand outlet 10 and oil export 11.
The described day with fog 7 of pouncing on adopts silk screen to catch mist filler wall.
The course of work of the present utility model is as follows: foaming crude oil tangentially enters vertical gas-liquid separator 1 by former oil-in 2 and carries out first separation, the descending oil export 11 from the bottom of liquid flows out, sand is discharged from the sand outlet 10 that is positioned at the bottom, the gas that contains certain foam that flash separation goes out flows into built-in cyclone separator 3 by differential pressure from cyclone air inlet 9 and carries out secondary separation, when fluid rotates at a high speed in cyclone separator, drop that the specific ionization air tightness is big and broken foam are done rotation at a high speed along wall, foam is constantly clashed into, friction, break, coalescent and flow in the oil reservoir along the standpipe wall, and the little free gas of density flow to left chamber along cyclone separator middle part wireway 5, flow out from the gas outlet 6 that is positioned at the device top after pouncing on day with fog 7 to enter the further coarse separation in right ventricle, the drop under holding back flows into the liquid layer of vertical gas-liquid separator 1 from catheter 4; Still contain a certain amount of foam and free gas in the first separation process in the isolated liquid, they spread in liquid phase, cushion and separated, enter built-in cyclone separator 3 with the gas of full flashing, finish to remove liquid in the gas and separate.This compact equipment, separative efficiency height, the cycle of operation are long, safe and reliable, applied widely, can be suitable for onshore oil field, especially the Oil-gas Separation of the foaming crude oil in the environment of offshore oilfield and inclement condition thereof.
