Technical field
The present invention relates to a kind of Dual-cyclone oil-gas mixer.
Background technology
In oil exploitation, output content from oil well often with multiphase mediums such as substantial amounts of natural gas and waters, is drained every year
, more than 70,000,000,000 degree, quantity is very surprising for the equivalent electric energy of the associated gas of waste.Multiphase mixed transportation technology is so that cost is relatively low, oil gas is adopted
The high outstanding feature of rate is day by day received significant attention and is applied.Used as the main dynamics equipment of multiphase conveying in oil field, oil gas is mixed
The conveying effect of defeated pump plays vital effect to the effectively utilizes of associated gas, but in severe field working conditions
Under, hydrocarbon content fluctuation inside pipeline, oil-gas mixed delivery pump are often affected by the fluid of various fluidised forms such as slug flow and are produced
Vapour lock and mechanical breakdown, therefore, blender of good performance is most important to the high-efficiency operation of oil-gas mixed delivery pump.
At present, the blender of oil-gas mixed delivery pump entrance is arranged on mainly using pipe-line mixer, static mixer or mixed
Close the forms such as vacuum tank.But high viscosity physical property condition, the on a large scale operating mode such as oil-gas ratio is faced, existing oil-gas mixer gradually exposes
Go out that mixed effect is bad, hydraulic loss is larger, processing difficulties, the problems such as flow uneven after mixing, especially (contain during atm number
When gas rate is more than 50%) cutout phenomenon be particularly acute, it is difficult to meet oil-gas mixed delivery pump stability operation requirement.Therefore it provides
A kind of simple structure, can adapt on a large scale oil-gas ratio change and the good oil-gas mixer of mixed effect for oil and gas multiphase flow system
System seems particularly necessary.
The content of the invention
For overcoming the disadvantages mentioned above of prior art, present invention offer one kind is rational in infrastructure, can be effectively improved air-fuel mixture work
The Dual-cyclone oil-gas mixer of condition, to improve air-fuel mixture effect, it is ensured that oil gas is still in interior change in a big way for oil-gas ratio
Uniformly can mix and steady flow.
The technical scheme is that：
A kind of Dual-cyclone oil-gas mixer, including blender body, the blender body includes straight section cylinder, cone section
Cylinder and tail barrel, the stub end of the cone section cylinder are connected with the straight section cylinder, it is described cone section cylinder little head end with
The tail barrel is connected；
The straight section cylinder is provided with air inlet pipe vertically, and the air inlet pipe includes the outer tube being coaxially disposed and inner tube, described
The outer wall of the inwall of outer tube and said inner tube encloses annular inlet passageway；The air inlet pipe is located at outside the straight section cylinder
End forms air inlet section, and the air inlet pipe extends to one section of formation air outlet section in the straight section cylinder；The said inner tube of air inlet section
On be arranged with stator, the outer tube of air outlet section is provided with exit ring, and the exit ring includes several rotations by the stator
Tangential outlet to circumferential array on outer tube, annular inlet passageway described in the tangential outlet and the straight section cylinder；
The side of the straight section cylinder is provided with tangential direction pipe, the rotation direction of the tangential direction pipe and the rotation direction of the stator
On the contrary.
Further, the exit ring includes 4 tangential outlets.
Further, it is provided with the 2-4 exit ring on the outer tube vertically, the tangential outlet of adjacent outlets circle is mutually handed over
It is wrong.
The invention has the beneficial effects as follows：
1st, stator makes gas phase produce eddy flow state, and the liquid phase of feed tube is in opposite direction with the eddy flow of gas phase, forms double-cyclone
Flip Trim mixed mode, gas-liquid mixed are uniform；
2nd, can adapt to oil-gas ratio change on a large scale and mixed effect is good；
3rd, simple structure, it is not necessary to arrange mechanical agitation, can rationally arrange the quantity of exit ring according to the actual requirements, with full
The mixed uniformly demand of foot.

Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Referring to the drawings, a kind of Dual-cyclone oil-gas mixer, including blender body, the blender body includes straight section
Cylinder 11, cone section cylinder 12 and tail barrel 13, the stub end of the cone section cylinder 12 are connected with the straight section cylinder 11, described
The little head end of cone section cylinder 12 is connected with the tail barrel 13；
The straight section cylinder 11 is provided with air inlet pipe vertically, and the air inlet pipe includes the outer tube 21 being coaxially disposed and inner tube
22, the outer wall of the inwall of the outer tube 21 and said inner tube 22 encloses annular inlet passageway 23；The air inlet pipe is located at described
One end outside straight section cylinder 11 forms air inlet section 26, and the air inlet pipe extends to one section of formation outlet in the straight section cylinder 11
Section 27；Stator 24 is arranged with the said inner tube 22 of air inlet section 26, and the outer tube 21 of air outlet section 27 is provided with exit ring, described
Exit ring includes several tangential outlets 25 by the rotation direction circumferential array of the stator 24 on outer tube 21, the tangential outlet
The 25 connections annular inlet passageway 23 and the straight section cylinder 11；
