Background technology
In the surface gathering system of oil field, mainly use various gas-liquid separators at present, the natural G﹠O in the oil well produced oil gas aqueous mixtures is separated, realize the liquid metering then or produce metering.Common gas-liquid separator is made up of one group of gas separation umbrella, a fluid separation applications umbrella, the first-class simple member of primary separation, its gas, liquid only rely on gravity to separate, the separative efficiency of this gas-liquid separator is low, speed is slow, the separating effect of gas phase thing and liquid phase thing is undesirable, and the cyclone separator arrangement volume is also bigger, use this separator to handle viscous crude and frothy crude oil, the time of staying of liquid in separator is long, gas-liquid separation is not thorough, causes the error in dipping of crude oil and gas bigger yet.Therefore, some rely on the gas-liquid separator of centrifugal force separation gas phase thing and liquid phase thing to be invented by rotating gas-liquid mixture at a high speed, because the volume of this spiral-flow type gas-liquid separator is little, separating rate is fast, effective, and has development potentiality preferably, as the patent No. is the Chinese utility model patent " a kind of spiral-flow type gas-liquid separator " of ZL200720108504.0 (publication number is CN201055811Y), discloses so a kind of gas-liquid separator.It includes cylindrical barrel body, the top of this cylindrical barrel body sidewall, middle part, bottom are respectively arranged with escape pipe, crude oil input pipe, the drain pipe that is connected with cylindrical barrel body, wherein, the relative cylindrical barrel body of crude oil input pipe is tilted to down, and tangent with the sidewall of cylindrical barrel body.This gas-liquid separator makes gas-liquid mixture can form eddy flow in cylindrical barrel body by the crude oil input pipe under being tilted to, and gas and fluid separation applications are come, and realizes gas-liquid separation.In the practice, liquid is oil water mixture, so, though the gas in the crude oil obtains separating, still can not be separated between oil and the water, requires further improvement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of spiral-flow type gas, oil and water separator that can realize gas, oil, water three phase separation at the present situation of prior art, its efficient work, stable, and separating effect is comparatively desirable.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this spiral-flow type gas, oil and water separator, comprise cylindrical barrel body, be respectively arranged with the escape pipe, fluid input tube, the outlet pipe that are connected with cylindrical barrel body inside on the barrel of the top of this cylindrical barrel body, middle part, bottom, wherein, the sidewall of described fluid input tube and cylindrical barrel body is tangent, it is characterized in that: the top of described cylindrical barrel body sidewall also is provided with a flowline, and this flowline is positioned at the top of described fluid input tube;
Between flowline and fluid input tube, also be provided with a dividing plate in the described cylindrical barrel body, this dividing plate is divided into oil collecting zone that is positioned at the dividing plate top and the Disengagement zone that is positioned at the dividing plate below with the cylindrical barrel body inner chamber, dividing plate central authorities are provided with one and are communicated with the dividing plate oil guide pipe of oil collecting zone and Disengagement zone up and down, and the bottom of this oil guide pipe is positioned under the bottom of described fluid input tube;
And, being positioned at the oil guide pipe below in the described cylindrical barrel body and also being provided with a funnel type cylinder, the top of funnel type cylinder is an osculum for big mouth, bottom.
During work, gas and oil aqueous mixtures band certain pressure tangentially enters in the cylindrical barrel body from fluid input tube, and produces rotation, directly enters in the funnel type cylinder subsequently; Because the open top of funnel type cylinder is big, bottom opening is little, and under the situation of flow speed stability, it is big that the flow velocity on the velocity ratio top of funnel type cylinder lower part comes, thereby more to the lower part of funnel type cylinder, and the suffered centrifugal force of mixture is just big more; In addition, centrifugal force according to object generation when rotating at a high speed, all particles all will be subjected to the centrifugal action than the big manyfold of himself weight in centrifugal field, the centrifugal force size is directly proportional with the gravity of particle itself, because gas phase thing density is less than the density of liquid phase thing, the density of oil phase thing is less than the density of aqueous-phase material, the suffered centrifugal force of gas phase thing is little more a lot of than liquid phase thing, and the centrifugal force that the oil phase thing is subjected to is littler than aqueous-phase material, gas in addition, oil, water has different density respectively and makes each phase thing gravity difference, air supporting is on pasta, and on oil swims on water the face, at gravity, centrifugal force, under the synergy of buoyancy, aqueous-phase material can be thrown to the inside edge of funnel type cylinder, and the gas phase thing can collect in the center of top of funnel type cylinder, the oil phase thing also is extruded to the top central authorities of funnel type cylinder, the density of gas phase thing is littler and directly rise to escape pipe by oil guide pipe than oil phase thing, and finally overflow from escape pipe, and the oil phase thing progressively increases after assembling, then cover over against the oil guide pipe of funnel type cylinder central authorities and export to flowline, and aqueous-phase material is in funnel type cylinder eddy flow, flow downward, osculum from the funnel type cylinder flows into the cylindrical barrel body bottom at last, and, finally realize gas phase from outlet pipe output, oil phase, each self-separation of water.
For ease of funnel type cylinder fixing in cylindrical barrel body, can be provided with a porous plate outside the described funnel type cylinder, porous plate has a center through hole that supplies the funnel type cylinder to plug, and this porous plate links to each other with the cylindrical barrel body inwall.Like this, funnel type cylinder top is big and the bottom is little, just can be fixed on by the porous plate of central openings in the cylindrical barrel body, and porous plate is that 1/4 place of whole height is good to be arranged on bottom the funnel type cylinder.
For guaranteeing the quality of the final aqueous-phase material of exporting, the position of described outlet pipe can be the top that is positioned at funnel type cylinder bottom, has guaranteed that aqueous-phase material can precipitate a period of time.
Because oil field produced oil gas aqueous mixtures inevitably can have solid suspension, carry out gas and oil moisture from the time, solid suspension can be followed the rotation at a high speed in cylindrical barrel body together of gas and oil aqueous mixtures, because solid suspension density is than water height, under action of centrifugal force, most of solid suspension can move downwards along with the fluid of rotation, then accumulate in the bottom of cylindrical barrel body, therefore, can offer a sewage draining exit in the bottom of described cylindrical barrel body, the solid suspension that accumulates in the cylindrical barrel body bottom so just can be discharged outside the cylindrical shell from this sewage draining exit.
For ease of installing and fixing of cylindrical barrel body, the bottom of described cylindrical barrel body can be provided with skirt support.
As further improvement, at the higher relatively gas and oil aqueous mixtures of gassiness ratio, for making this spiral-flow type gas-liquid separator have separating effect preferably, on described fluid input tube, can also be connected with the pre-input pipe of a U type, one end of the pre-input pipe of this U type links to each other with this fluid input tube, and the other end is positioned at the below of fluid input tube.Worked as the higher relatively gas and oil aqueous mixtures of gassiness ratio like this before entering cylindrical barrel body, the gas and oil aqueous mixtures can enter cylindrical barrel body by fluid input tube through the pre-input pipe of U type earlier again, promptly, gas phase thing in the gas and oil aqueous mixtures is lighter than liquid phase thing because of proportion, the meeting of gas and oil aqueous mixtures preliminary carrying out oneself separate, most of gas phase thing will be directly from the pre-input pipe of U type, fluid input tube enters into the top of column body, directly discharge through behind the oil guide pipe from escape pipe, obviously accelerated the separative efficiency of gas phase thing, by this pretreated mode, also improved the gas oil-water separation greatly simultaneously.
Compared with prior art, the invention has the advantages that: by tangentially entering the eddy flow that produces, and the utilization of cooperation funnel type cylinder, it is just big more that centrifugal force is walked in the bottom of the past more funnel type cylinder of fluid, and the centrifugal force that oil droplet is subjected to is less than water, guarantee that most of oil droplet can not enter into the lower part of funnel type cylinder, this just makes the less You Heshui of density variation also can separate well, even littler oil droplet also can be separated from water, and gas is pooled to central authorities naturally by discharging from escape pipe behind the oil guide pipe, finally realizes gas phase, oil phase, each self-separation of water; Volume of the present invention is little, separative efficiency is high, easy maintenance, is applicable to various oils qualities.
