Abstract
The utility model discloses a gas-liquid separator-filter for wellhead associated gas, which is designed for removing moisture and solid impurities in the associated gas, and meeting the supercharging requirement of a compressor. A barrel of the filter is fixed at a support; a connecting pipe is connected to an ellipsoidal head which is connected to the bottom end of the barrel; a flange port and a gas-liquid inlet are connected to the lower part of the barrel; a differential pressure gauge pipe mouth, a pressure gage pipe mouth and a silk screen barrel are connected to the upper part of the barrel; the bottom surface of a support plate in the barrel is connected with a liquid discharge pipe and a baffle plate which is corresponding to the gas-liquid inlet; an overflow plate which is inclined is arranged below the gas-liquid inlet; a filter piper is connected to the top surface of the support plate; a horizontal hanging cover quick-opening blind plate is connected to the top of the barrel. According to the gas-liquid separator-filter for wellhead associated gas, the separation and filter functions are integrated, and the gas-liquid separator-filter is suitable for separation of the wellhead associated gas in an oil field, and is capable of removing the moisture and few solid impurities in natural gas so as to meet the supercharging requirement of the compressor. The gas-liquid separator-filter for wellhead associated gas is high in separation efficiency, reasonable in structure, low in manufacturing cost, and obvious in economic benefits.
Description
Technical field
The utility model relates to a kind of well head associated gas gas-liquid separation filter, belongs to the associated gas technical field.
Background technology
From stratum, the associated gas of extraction generally all contains saturation vapour and oil ingredient, when distribution pressure and variation of ambient temperature, steam is separated out from natural gas, form the solid hydrates such as aqueous water and ice, can accelerate the gas transmission pressure drop, reduce pipeline gas transmission ability, when serious, can stop up valve and pipeline, affect tight gas supply.When natural gas that conveying contains acid medium, aqueous water can accelerate the corrosion of acidic components to tube wall and valve, reduces the application life of pipeline.Therefore, natural gas must carry out processed, with intake pipeline after reaching the moisture tolerance index of regulation.
In prior art, after natural gas enters eliminator, utilize that momentum is poor, gravitational difference carries out just separating with collision.Due to the significant weight difference of the gentle existence of oil, both just can separate within several seconds, and oil is less with the weight difference of water, and the separation of oil, water needs a few minutes.Separate the liquid mist the most difficult from gas, contain tiny liquid pearl in the liquid mist, be suspended in not sedimentation in gas.
General collision type demister device is used stainless steel cloth, with coalescent mist, increase liquid bead footpath gradually and rely on the mode of gravity to converge into drop, splashes into poly-liquid zone.This mesh mist eliminator is best suited for the gas purification of high oil-gas ratio, and New Year's Eve, efficiency can reach 99.9%, yet its paraffin collected, hydrate, sand and other solid particle are very easy to stop up silk screen, are not suitable for the first separation of well head associated gas.
Summary of the invention
The purpose of this utility model is to provide a kind of well head associated gas gas-liquid separation filter, with the moisture in the removal associated gas and a small amount of solid impurity, meets the requirement of compressor boost.
Concrete technology contents of the present utility model is as follows:
The cylindrical shell of this strainer is fixed on bearing, connecting tubes on the ellipse head of connection cylindrical shell bottom; Cylindrical shell bottom adpting flange interface and gas-liquid entrance, top connects differential manometer ozzle, pressure meter ozzle and wire mesh tube; Inner barrel is separated by gripper shoe, the deflection plate of gripper shoe bottom surface connected drainage pipe and corresponding gas-liquid entrance, and gas-liquid entrance below is provided with and tilts to connect cylinder inboard wall, overflow plate that be the large semicircle arc-shaped; Support plate top surface vertically connects filter pipe, and filter pipe is distributed on half gripper shoe of relative wire mesh tube, and the filter pipe top connects pressing plate, and pressing plate connects cylinder inboard wall by back-up block; Connection level in cylindrical shell top is hung and is covered fast opening blind, and outer wall connects nameplate.
This strainer hold concurrently to separate and filtering function in one, be applicable to the separation of oil field shaft mouth associated gas, can remove moisture content in natural gas and a small amount of solid impurity, to meet the requirement of compressor boost.This strainer separative efficiency is high, rational in infrastructure, low cost of manufacture, remarkable in economical benefits.
The accompanying drawing explanation
Fig. 1 is well head associated gas gas-liquid separation filter structural representation.
The top view that Fig. 2 is pressing plate, filter pipe and wire mesh tube.
The specific embodiment
Embodiment:
With reference to Fig. 1 and 2, embodiment of the present utility model is further illustrated:
This strainer comprises that bearing 1, ellipse head 2, flange connecting pipe 3, gas-liquid entrance 4, differential manometer ozzle 5, pressure meter ozzle 6, back-up block 7, pressing plate 8, level are hung and covers fast opening blind 9, wire mesh tube 10, nameplate 11, filter pipe 12, gripper shoe 13, deflection plate 14, cylindrical shell 15, overflow plate 16, discharging tube 17 and take over 18:
The operating principle of this well head associated gas gas-liquid separation filter is as follows:
The well head associated gas of oil-containing, water and solid impurity enters cylindrical shell 15 through gas-liquid entrance 4, gets on deflection plate 14, and deflection plate 14 absorbs the momentum of gas-liquid flow, makes it along cylindrical shell 15 inwall rotations, and fluid is realized crude separation by the centrifugal force difference of gas, liquid.Isolated gas is routed up under deflection plate 14, upwards flows.Through filter pipe 12 time, liquid mist in gas is gathered into larger liquid pearl, contrary airflow direction drops onto on gripper shoe 13, then falls into the liquid accumulation regions in ellipse head 2 along discharging tube 17, and the gas after the filtering droplet enters down-stream system through the wire mesh tube 10 of stainless steel.Isolated liquid also is pooled in ellipse head 2 through deflection plate 14 and overflow plate 16.
