Summary of the invention
Technical problem to be solved by this invention is to provide a kind of double-barrel spiral-flow type gas-oil-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 double-barrel spiral-flow type gas-oil-water separator, it is characterized in that: comprise first cylindrical barrel body and second cylindrical barrel body, be disposed with first escape pipe, first flowline, first input pipe, the outlet pipe that is connected with the first cylindrical barrel body inside on the barrel of this first cylindrical barrel body to the bottom from the top, wherein, the sidewall of described first input pipe and first cylindrical barrel body is tangent;
Between first flowline and first input pipe, also be provided with a dividing plate in described first 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 first 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 first input pipe;
And, being positioned at the oil guide pipe below in described first 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;
And the barrel of described second cylindrical barrel body is disposed with second escape pipe, second input pipe, oil phase thing input pipe, second flowline to the bottom from the top, wherein, first escape pipe of described first cylindrical barrel body is connected with second input pipe, and described oil phase thing input pipe is connected with first flowline of first cylindrical barrel body;
And, described second input pipe is the L type, relative second cylindrical barrel body in end of vertical part is tilted to down in second input pipe, and tangent with the sidewall of second cylindrical barrel body, and described relatively first input pipe in the end of lateral part is perpendicular and coupled logical in second input pipe.
During work, gas and oil aqueous mixtures band certain pressure tangentially enters in first cylindrical barrel body from first input pipe, 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, the initial gross separation of water;
When the tape input of gas and oil aqueous mixtures, when the gas that is entrained with oil droplet is flowed through first input pipe, can flow into naturally because density is less with the perpendicular second input pipe lateral part of first input pipe in, and the vertical part of second input pipe of flowing through and tangentially entering in second cylindrical barrel body, thereby the gas phase thing is come out from the pre-separation of gas and oil aqueous mixtures, simultaneously, the oil phase thing of exporting from first flowline of first cylindrical barrel body enters in second cylindrical barrel body by oil phase thing input pipe once more, produce eddy flow with gas, and in second cylindrical barrel body, carry out once more the separating of gas phase thing and oil phase thing, at last, the gas phase thing is discharged from second escape pipe, and the oil phase thing is discharged from second flowline.
For ease of funnel type cylinder fixing in first 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 first 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 first 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 of first cylindrical barrel body, 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.
For guaranteeing the quality of the final gas phase thing of exporting of second cylindrical barrel body, the port of export of described second escape pipe can be opened the side wall upper part at second cylindrical barrel body, the entrance point of second escape pipe extend into central authorities in the top of second cylindrical barrel body from bottom to top, and, above the second escape pipe entrance point, also be provided with a umbrella top cover, between umbrella top cover and entrance point, be connected with support bar, the setting of stretching into setting and umbrella top cover from bottom to top of second escape pipe, the oil droplet that condenses upon on the second cylindrical barrel body top inner wall can accident not splashed in second escape pipe, but can slide into the second cylindrical barrel body participation oil along the umbrella top cover, gas separates.
Because the oil gas aqueous mixtures in cylindrical barrel body needs rotation at a high speed, has certain pressure, for the ease of installing, automatically control moves needed sensor, realize the automatic control operation of oil gas aqueous mixtures, a pair of fluid level transmitter pressure guiding pipe, the adapter of Pressure gauge impulse, the adapter of pressure transmitter impulse and relief valve port can also be set on the sidewall of second cylindrical barrel body.
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 first sewage draining exit respectively in the bottom of described first cylindrical barrel body and second cylindrical barrel body, second sewage draining exit, the solid suspension that accumulates in each 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 first cylindrical barrel body and second cylindrical barrel body can be provided with a skirt support.
As further improvement, at the higher relatively gas and oil aqueous mixtures of gassiness ratio, for making this double-barrel spiral-flow type gas-liquid separator have separating effect preferably, on described first input pipe, 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 first input pipe, and the other end is positioned at the below of first input pipe, also is provided with the small-bore mouth of pipe on the other end, that is, the caliber of the mouth of pipe is less than the caliber of the pre-input pipe main body of U type.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 be earlier through the pre-input pipe of U type, 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 directly enter into second cylindrical barrel body from L type second input pipe, obviously accelerated the separative efficiency of gas phase thing, simultaneously by this pretreated mode, also improved the gas oil-water separation greatly, and the other end of the pre-input pipe of U type has reduced the volume of volume exclusion towards first cylindrical barrel body.And the mouth of pipe of different tube diameters connects design, it is had alleviate the rectified action that mixture flows, and is adapted to the gas and oil aqueous mixtures of different oil wells and different in flow rate.
Compared with prior art, the invention has the advantages that: for first cylindrical barrel body, 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;
For second cylindrical barrel body, produce eddy flow by tangentially entering, entrained oil in the gas is dripped can walk downward along the madial wall of second cylindrical barrel body, gas then to central authorities compile and upwards walking discharges from escape pipe then;
