Description
Technical field
The present invention relates to underground gas production field, in particular to a kind of rotational flow atomized spray injector.
Background technology
At home all can be in various degree in most gas wells there is ponding in shaft bottom, for the gas of bottom water or side water be present
Well, liquid-gas ratio will gradually increase in recovery process, if adjustment liquid-gas ratio or shaft bottom hydrops exclude well not in time not in time
Mouthful, this can cause the normal production of gas well, or even gas well is drowned and causes to stop production, therefore correctly predicted gas well is different degrees of
Jacking capacity under liquid content selects the water drainage-gas recovery technology of suitable gas well to have important reality according to the actual conditions of gas well
Meaning.
The liquid that gas well shaft bottom just starts to occur during a small amount of hydrops in pit shaft can utilize the climbing power band of itself by gas
Go out pit shaft, gas well can also be produced normally, and at this moment the most stream flow velocity of gas well air-flow is referred to as gas well and takes liquid critical flow velocity, corresponding gas
Flow is referred to as gas well and takes liquid critical flow；When the actual flow velocity of gas in pit shaft is less than critical flow velocity, air-flow cannot be by well
Interior liquid takes well head out of using the climbing power of itself.And in the prior art, generally use emple hole, liquid obtains after over pressurizeed
Larger kinetic energy is obtained, liquid will be ejected with very big speed after nozzle, be hindered in surface tension of liquid, viscosity and air
Under power interaction, liquid by drippage, smooth flow, it is wavy flow to spray flow and gradually change, finally conveniently realize the two-phase of gas-liquid
Separation；But because the current discharged in emple hole have surface tension, therefore during liquid is changed into spray flow,
Need constantly to meet that when ejecting with very high speed with surrounding air friction occurs for liquid and separates to underground pressurization
Atomization, then the air pressure of underground is higher, and the safety reliability faced during gas production is lower, easily triggers security incident.
The content of the invention
It is an object of the invention to provide a kind of rotational flow atomized spray injector, facilitates gas-liquid quickly independently to rise outside discharge well,
Reach the purpose for improving gas production safety reliability simultaneously.
The purpose of the present invention is achieved through the following technical solutions：
A kind of rotational flow atomized spray injector, including nozzle inner core and the nozzle housing that is set in outside nozzle inner core, nozzle housing
End be provided with spurt hole, internal conical surface is set in described nozzle inner core one end, and the internal conical surface and nozzle housing is interior
Wall forms air inlet cavity, and the nozzle inner core other end is provided with the through hole of face spurt hole, multiple eddy flow leaves are provided with through-hole wall
Piece, and the inwall of through hole and nozzle inner core forms eddy flow cavity.Nozzle is fixed on to the outlet side of gas well, when the gas-liquid in gas well
Two-phase mixture is begun to ramp up under the promotion of borehole pressure, and gas-liquid mixture is entered in inlet chamber body by internal conical surface excessively
Volume compression is carried out to it, and then improves the flowing velocity of gas-liquid mixture, when gas-liquid mixture enters eddy flow cavity, fluid
Contact with each other with swirl vane, rotated fluid driven by swirl vane, finally utilize centrifugal force caused by rotation by gas-liquid
Mixture is thrown away from spurt hole；
When the flow very little of gas-liquid mixture, when centrifugal force is more than surface tension of liquid, it is by what is thrown away in spurt hole
Larger-size big drop, now liquid directly split into drop；When flow increases, liquid is more into quantity by rotary splitter
Thread jet, the fluidised form of liquid is extremely unstable, liquid leave rotating vane end and by spurt hole spray a segment distance after, directly
Connect and rubbing action occurs and is separated into droplet with air, form mitoschisis drop, when flow continues increase, brin is mutual
Connect into liquid film, as liquid film is outwards extended to thinner liquid film, and so that friction occurs for the air of very high speed and surrounding and
Separation atomization, drop is split into by film-form so that vaporific gas-liquid mixture is sprayed in spurt hole, while in normal use
The gas-liquid two-phase in gas well is extracted under operating pressure, to facilitate the gas-liquid separation process in later stage.
Further, the end of the nozzle inner core is provided with annular groove, and the eddy flow cavity passes through circular hole and annular
Groove connects.Annular space is formed between annular groove and the inwall of nozzle housing, gas-liquid mixture is when that will pass through swirl vane
Entered by circular hole in annular space, reduce stream of the gas-liquid mixture in eddy flow cavity close to its inner wall section to a certain extent
Layer movement velocity, avoids gas-liquid mixture from directly being impacted to swirl vane, influences stream after preventing swirl vane Local Damaged
The rotation of body, improve the atomizing effect of gas-liquid mixture in spurt hole.
Further, multiple swirl vanes are in a ring and array is rotatably arranged on inwall, adjacent two eddy flows
The angle that blade is formed with through hole axle center is α, and α is 72 ° 90 ° or 120 °.Mixed for the gas-liquid in vortex chamber body
The flowing velocity of compound, swirl vane can freely swing with the motion of liquid, to adjust the size of liquid centrifugal force and side
To, and then ensure vaporific in the gas-liquid mixture position of spurt hole discharge；And preferably, by two adjacent swirl vanes with
The angle that through hole axle center is formed is arranged to 72 ° 90 ° or 120 °, i.e., using 34 again or 5 pivoting leafs
Piece is rotatably arranged on through-hole wall, makes full use of the regulation performance of swirl vane convection body, ensures that the fluid of high-speed motion exists
Vaporific droplet is formed in spurt hole, facilitates the separation of gas-liquid and the lasting rising of underground gas-liquid two-phase in being acted on well.
Further, the diffusion hole of nozzle housing end, the outlet side of the diffusion hole and spurt hole are opened in addition to
Connection.The misty liquid droplets range of scatter projected by spurt hole is larger, is unfavorable for collection of the operation to misty liquid droplets on well, with jet flow
The misty liquid droplets that the diffusion hole of hole connection can spray to radiation carry out gathering aggregation, are allowed to be directly entered the receiving in device on well
In chamber.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention when flow continue increase when, brin is interconnected to liquid film, with liquid film be outwards extended to it is thinner
Liquid film, and friction is occurred with the air of surrounding with very high speed and separates atomization, drop is split into by film-form so that spraying
Discharge orifice sprays vaporific gas-liquid mixture, while extracts the gas-liquid two-phase in gas well under the operating pressure of normal use,
To facilitate the gas-liquid separation process in later stage；
2nd, annular space is formed between annular groove of the invention and the inwall of nozzle housing, gas-liquid mixture will pass through rotation
Entered when flowing blade by circular hole in annular space, reduce gas-liquid mixture to a certain extent in eddy flow cavity close to its inwall
Partial fluid layer movement velocity, avoids gas-liquid mixture from directly being impacted to swirl vane, prevents swirl vane Local Damaged
The rotation of fluid is influenceed afterwards, improves the atomizing effect of gas-liquid mixture in spurt hole；
3rd, the angle that the present invention is formed two adjacent swirl vanes and through hole axle center be arranged to 72 ° or 90 ° or
120 °, i.e., using 34 again or 5 rotating vanes be rotatably arranged on through-hole wall, make full use of swirl vane
The regulation performance of convection body, ensure that the fluid of high-speed motion forms vaporific droplet in spurt hole, facilitate gas in being acted on well
The separation of liquid and the lasting rising of underground gas-liquid two-phase.
