Description
Technical field
The present invention relates to underground gas production field, in particular to a kind of aqueous vapor well atomizing spray component.
Background technology
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 aqueous vapor well atomizing spray component, reaches and improves gas production safety reliability
Purpose.
The purpose of the present invention is achieved through the following technical solutions：
A kind of aqueous vapor well atomizing spray component, including core body and the housing that is set in outside core body, the end of housing is set
There is spurt hole, internal conical surface is set in described core body one end, and the inwall of the internal conical surface and housing forms air inlet cavity, core
The body other end is provided with the through hole of face spurt hole, and multiple swirl vanes, and the inwall of through hole and core body are provided with through-hole wall
Form eddy flow cavity；Also include two to be staggered the two of core body axis through housing and the stomata of core body, two stomatas
Side, and the outlet side of the stomata is in the opposite direction bending of the gas liquid two-phase flow along core body.Nozzle is fixed on going out for gas well
Gas 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 air inlet
Volume compression is carried out to it by internal conical surface after in cavity, and then improves the flowing velocity of gas-liquid mixture, in gas-liquid mixed
When thing enters eddy flow cavity, fluid contacts with each other with swirl vane, is rotated fluid driven by swirl vane, finally utilizes rotation
Centrifugal force caused by turning 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, 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；
Wherein by injecting steam to stomata, the steam poured into enters vortex chamber as working media along the inwall of stomata
In body, and bent in the end of stomata to the direction that gas-liquid mixture moves, i.e. steam is relatively moved with gas-liquid two-phase, is steamed
The surface tension of resistance caused by vapour and gas-liquid mixture, viscous interaction, swiftly flowing steam and relatively low speed
The gas-liquid mixture or liquid film of motion mutually produce vibrations, friction so that liquid is sprayed by drippage, smooth flow, wavy flow direction
Stream gradually transformation, final liquid crushing is tiny liquid；Then rise rapidly by the CENTRIFUGAL ACCELERATING of swirl vane again, it is convenient
Gas-liquid quickly independently rises outside discharge well, while reaches the purpose for improving gas production safety reliability.
Further, the end of the core body is provided with annular groove, and the eddy flow cavity passes through circular hole and annular groove
Connection.Annular space is formed between annular groove and the inwall of housing, gas-liquid mixture passes through circular hole when that will pass through swirl vane
Enter in annular space, reduce gas-liquid mixture to a certain extent and move speed close to the fluid layer of its inner wall section in eddy flow cavity
Degree, avoids gas-liquid mixture from directly being impacted to swirl vane, prevents the rotation of influence fluid after swirl vane Local Damaged,
Improve the atomizing effect of gas-liquid mixture in spurt hole.Also include the diffusion hole for being opened in shell end, the diffusion hole and spray
The outlet side connection of discharge orifice.The misty liquid droplets range of scatter projected by spurt hole is larger, is unfavorable on well operation to misty liquid droplets
Collection, the diffusion hole connected with spurt hole can to radiation spray misty liquid droplets carry out gathering aggregation, be allowed to be directly entered well
In accommodating chamber in upper device.
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.
