Description
Technical field
The present invention relates to underground gas production field, in particular to a kind of quick air collecting pipe of drainage underground.
Background technology
At home all can be in various degree in most gas wells there is ponding in shaft bottom, for there are the gas of bottom water or side water
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 known as gas well and takes liquid critical flow velocity, corresponding gas
Flow is known 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 being overpressurized
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 the current due to being discharged in emple hole have surface tension, 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 that when gas production is faced is lower, easily triggers security incident.
The content of the invention
It is an object of the invention to provide a kind of quick air collecting pipe of drainage underground, facilitates gas-liquid quickly independently to rise discharge
Outside well, while achieve the purpose that to improve gas production safety reliability.
The purpose of the present invention is achieved through the following technical solutions：
A kind of quick air collecting pipe of drainage underground, including nozzle inner core and the nozzle housing that is set in outside nozzle inner core, spray
The end of mouth shell is equipped with spurt hole, and internal conical surface is set in described nozzle inner core one end, and outside the internal conical surface and nozzle
The inner wall of shell forms air inlet cavity, and the nozzle inner core other end is provided with the through hole of face spurt hole, is provided with through-hole wall multiple
Swirl vane, and the inner wall of through hole and nozzle inner core forms eddy flow cavity；Two are further included in nozzle housing and nozzle
The stomata of core, is provided with the convective tank of annular in the middle part of nozzle inner core, and two stomatas are symmetricly set on the both ends of convective tank, and institute
State the outlet side internal diameter of stomata and successively decrease being radially directed towards along nozzle inner core on the direction in axle center.Nozzle is fixed on to the outlet of gas well
End, when the gas-fluid two-phase mixture in gas well is begun to ramp up under the promotion of borehole pressure, gas-liquid mixture enters inlet chamber
Volume compression is carried out to it by internal conical surface after in vivo, and then improves the flowing velocity of gas-liquid mixture, in gas-liquid mixture
During into eddy flow cavity, fluid contacts with each other with swirl vane, is rotated fluid driven by swirl vane, finally utilizes rotation
The centrifugal force of generation throws away gas-liquid mixture 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, at this time liquid directly split into drop；When flow increases, liquid is more into quantity by rotary splitter
Filamentous jet stream, the fluidised form of liquid is extremely unstable, after liquid leaves rotating vane end and sprays a distance by spurt hole, 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 with 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；
The convective tank of annular is wherein provided with the middle part of nozzle inner core, injects air to stomata, the air poured into is in stomata
End is compressed, i.e., further increases the jet velocity of air, and stomata is symmetrical arranged along the convective tank of annular, and then has two gas
The air stream that hole sprays mutually liquidates, and can be carried out in convective tank a period of time, the gas-liquid mixed of flowing in vortex chamber body
Thing mixes under the cylindrical environment that convective tank is formed with air, swiftly flowing air and the gas-liquid of relatively low speed movement
Mixture or liquid film mutually produce vibrations, friction so that liquid crushing is tiny liquid；Then again by swirl vane
CENTRIFUGAL ACCELERATING rises rapidly, facilitates gas-liquid quickly independently to rise outside discharge well, while reach and improve gas production safety reliability
Purpose.
Further, the end of the nozzle inner core is equipped 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 inner wall 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 causing to impact to swirl vane, influences stream after preventing swirl vane Local Damaged
The rotation of body, improves the atomizing effect of gas-liquid mixture in spurt hole.
Further, the diffusion hole for being opened in nozzle housing end, the outlet side of the diffusion hole and spurt hole are further included
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 radiation carry out gathering aggregation, are allowed to be directly entered the receiving in device on well
In chamber.
Compared with prior art, the present invention have 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 inner wall 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 inner wall
Partial fluid layer movement velocity, avoids gas-liquid mixture from directly causing to impact to swirl vane, prevents swirl vane Local Damaged
The rotation of fluid is influenced afterwards, improves the atomizing effect of gas-liquid mixture in spurt hole.
