Abstract
The invention provides a multi-point injection gas-liquid mixer. The multi-point injection gas-liquid mixer comprises a liquid pipe 1 for conveying liquid, wherein the liquid pipe 1 is externally provided with a ring-shaped pipe 2 surrounding the liquid pipe 1; the ring-shaped pipe 2 is provided with an associated-gas feeding hole 21; the pipe wall of the liquid pipe, which is spaced with the ring-shaped pipe 2, is provided with spraying through holes 13; the spraying through holes 13 incline from one side of the ring-shaped pipe 2 towards one side of the liquid pipe 1 along the flowing direction of the liquid in the liquid pipe; the spraying through holes 13 are uniformly distributed along the circumference of the liquid pipe 1 so as to form a plurality of injection points of the associated gas towards the liquid. The multi-point injection gas-liquid mixer provided by the invention has the advantages that without stirring of mechanical blades and by means of fluid, gas-liquid mixing is realized, the gas-liquid mixing effect is good, a great amount of gas can be mixed, and the energy can be saved.
Description
Technical field
The present invention relates to a kind of air and liquid mixer for oil and gas multiphase flow pump intake.
Background technology
Air and liquid mixer is placed in oil and gas multiphase flow pump intake, and its function introduces pump intake by after oil well associated natural gas and crude oil and water Homogeneous phase mixing.Air and liquid mixer belongs to the critical component in oil and gas multiphase flow pump installation, and its mixed effect directly affects pump and normally runs.
Existing air and liquid mixer generally adopts mechanical agitation mode, and motor band moving vane carries out gas-liquid mixed, has that gas-liquid mixed is uneven, high, the baroque shortcoming of inefficiency, energy consumption.
The open CN103316603 of Chinese invention patent discloses a kind of blender adding ozone gas in running water, stirring vane is provided with in water stream channel, the side of water stream channel is provided with an ozone admission gear, and ozone admission gear passes through a through hole to water stream channel injecting gas.The effect of its gas-liquid mixed depends on blade.Usually, due to the restriction of mechanism size, the quantity of blade mechanism can not be a lot, and therefore mixed effect is bad.And limit by structure, gas spray site is few, and the intake of gas is less, being only suitable for for the little occasion of gas mixed volume, needing the occasion incorporating the gas of larger amt in liquid, just can not using.
Summary of the invention
The present invention will overcome the above-mentioned shortcoming of prior art, provides the air and liquid mixer that a kind of gas-liquid mixed is effective, can mix a large amount of gas.
Multi-point injection air and liquid mixer, comprise the liquid pipe of conveying liquid, it is characterized in that: be provided with the ring pipe around liquid pipe outside described liquid pipe, ring pipe have associated gas inlet port, described liquid pipe and ring pipe interval tube wall on offer multiple injection through hole; The flow direction of described injection through hole from ring pipe side to liquid pipe side along liquid liquid in pipe tilts, and described injection through hole distributes along the even circumferential of liquid pipe, forms the multiple spray site of associated gas to liquid.
Further, angle a=10 ~ 80 ° of the axis of described injection through hole and the axis of liquid pipe.
Further, associated gas inlet port is arranged along the tangential direction of described ring pipe.
The advanced liquid-in pipe exterior annular space of associated gas, then enter liquid-in pipe by the injection through hole tiltedly established, spray through hole and enclose around liquid pipe one, form multi-point injection; Air-flow tilts to enter liquid, can form eddy flow, be conducive to gas-liquid mixed.Associated gas is entered in liquid (crude oil and water) by some oblique circular holes, makes it Homogeneous phase mixing, contributes to gas-liquid homogeneous media and enters in pump chamber, realizes the outer defeated object of supercharging better.
The present invention, not by the stirring of mechanical blade, realizes gas-liquid mixed by fluid self.
Advantage of the present invention is: gas-liquid mixed is effective, can mix a large amount of gas, energy-conservation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
Further illustrate the present invention with reference to the accompanying drawings.
Multi-point injection air and liquid mixer, comprises the liquid pipe 1 of conveying liquid.Be provided with the ring pipe 2 around liquid pipe 1 outside described liquid pipe 1, ring pipe 2 have associated gas inlet port 21, described liquid pipe and 1 ring pipe 2 interval tube wall on offer multiple injection through hole 13; The flow direction of described injection through hole 13 from ring pipe 2 side to liquid pipe 1 side along liquid liquid in pipe tilts, and described injection through hole 13 distributes along the even circumferential of liquid pipe 1, forms the multiple spray site of associated gas to liquid.
In liquid pipe 1, the liquid that oil and water are mixed into flows to liquid outlet 12 from liquid inlet 11.The shape of spraying through hole 13 is generally circular.
Angle a=10 ~ 80 ° of the axis of described injection through hole 13 and the axis of liquid pipe.Associated gas inlet port 21 is arranged, so that associated gas forms eddy flow in ring pipe 2 along the tangential direction of described ring pipe 2.
The advanced liquid-in pipe exterior annular space of associated gas, then enter liquid-in pipe by the injection through hole tiltedly established, spray through hole and enclose around liquid pipe one, form multi-point injection; Air-flow tilts to enter liquid, can form eddy flow, be conducive to gas-liquid mixed.Associated gas is entered in liquid (crude oil and water) by some oblique circular holes, makes it Homogeneous phase mixing, contributes to gas-liquid homogeneous media and enters in pump chamber, realizes the outer defeated object of supercharging better.
Content described in this description embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as being only limitted to the concrete form that embodiment is stated, protection scope of the present invention also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
