Description
Technical field
The present invention relates to a kind of gas-liquid separation equipment, be specifically related to a kind of gas-liquid rotary turbine separation device, belong to Oil-gas Separation and gas dehydration technical field in oil-gas gathering and transportation system.
Background technology
Gas-liquid two-phase isolation technics traditional in petroleum industry has had good development, but has the subject matter of three aspects: the one, and conventional separation volume is large, weight is large; The 2nd, the useful energy in heterogeneous fluid is partially or completely consumed; The 3rd, in the time of foam and emulsification generation, separate not thorough.Along with the development of China's oil and gas industry, the demand for development of the exploitation in special marine oil gas field to oil and gas industry, gs-oil separator is from traditional gravity type to efficient, compact, energy-conservation future development, many oil companies pay special attention to the small-sized separator of recoverable energy in two-phase in the world, and drop into substantial contribution and research and develop.
At " TWO-PHASE REACTION TURBINE " (US4298311, etc. 1981.11.3) on the basis of patent, nineteen ninety-five, Hays has applied for the patent (US5385446 of " HYBRID TWO-PHASE TURBINE ", 1995.1.31), the concept of revolving wormgear separator has been proposed.
Pressure energy reforming unit---gas-liquid two-phase nozzle in mixing two-phase turbine in Hays patent, adopts the long-pending irregular runner in adjustable throat section to realize, although can realize Flow-rate adjustment to a certain degree, can not ensure the efficient utilization of fluid pressure energy; Liquid film after separation contacts with gas always, is unfavorable for reducing secondary and mixes; Separator gas blade adopts axial blade, and entire length is larger, and floor space is larger.
Summary of the invention
The object of this invention is to provide a kind of gas-liquid rotary turbine separation device, not only collect gas-liquid separation, gas dehydration and shaft work and be output in one, also by cyclone separator arrangement being improved to improve the utilization rate of separative efficiency and convection cell pressure energy, and reduce floor space, thereby overcome the deficiencies in the prior art.
The general principle of gas-liquid rotary turbine separation device of the present invention is to utilize two-phase nozzle that high-pressure two-phase fluid is converted into high-speed jet, this high-speed jet is impacted a separation rotor and is made its rotation along nearly tangential direction, the high centrifugal force that rotation produces separates heterogeneous fluid and produces shaft work, the shaft work producing can be for miscellaneous equipment as pump, and separated gas and liquid are by outlet drain separator separately.
A kind of gas-liquid rotary turbine separation device, comprise the housing of rack-mount hollow, via sealing and lubricating arrangement and be fixed on the rotating shaft in housing, housing is stretched out in one end of this rotating shaft, and there is the separation rotor that is positioned at housing inner chamber middle part to be fixed on the other end of rotating shaft, and one end adjacent with separation rotor of housing is provided with gas-liquid two-phase nozzle, it is characterized in that above-mentioned separation rotor comprises is fixed in rotating shaft, axially, be provided with successively the separator disk of annular collecting tank and annular air collecting chamber, described collecting tank is connected with Disjoint Cone, described collecting tank and air collecting chamber are communicated with respectively liquid reaction nozzle and gas reaction nozzle, and between collecting tank and air collecting chamber, be provided with annular demarcation strip.
Mix again in order further to reduce to separate rear gas-liquid, also can make further improvements above-mentioned housing, specifically the inner chamber of housing middle part is provided with liquid spiral case and the gas spiral case of being isolated by dividing plate in the axial direction side by side, and described liquid spiral case and gas spiral case are surrounded on respectively collecting tank and air collecting chamber.
Aforesaid liquid reaction nozzle is also connected with liquid conduits, thereby has guaranteed the utilization of the remaining kinetic energy of liquid to the ejection of liquid reaction nozzle and reduced to mix again.
Above-mentioned gas reaction nozzle is also connected with gas conduit, thereby has guaranteed the utilization of the remaining kinetic energy of gas to the ejection of gas reaction nozzle and reduced to mix again.
After the inner surface of Disjoint Cone that separation rotor of the present invention impacts separation rotor through the high speed dual-phase jet of two-phase nozzle, separation rotor rotation and complete gas-liquid separation, under the effect of centrifugal force, liquid flows into along the inner surface of Disjoint Cone the collecting tank separating in wheel, gas, through entering the air collecting chamber that separates wheel, has annular baffle to separate between collecting tank and air collecting chamber.The mixing again of gas-liquid two-phase after this structure has at utmost reduced to separate, has minimized gas and has carried secretly and the carrying of liquid, and has improved separative efficiency.
After gas and fluid separation applications, gas reaction nozzle and the liquid reaction nozzle by separation rotor discharged respectively, and the liquid outlet on separation rotor and gas exit passageway are made the deep-slotted chip breaker contrary with separation rotor direction of rotation by the present invention.This structure can utilize the high-head being produced by centrifugal field to fluid with the acceleration contrary with separation rotor direction of rotation, the angular momentum of the fluid that makes to become a mandarin reduces, thereby has reduced the value of the absolute velocity of fluid while leaving rotor.One of its Main Function is the moment of torsion that has increased axle, thereby has increased the possibility of output shaft work, and two of effect is that the absolute impact velocity that makes to act in separate housings remains on very low numerical value, has minimized the erosion to shell.
Connect in the outlet of arc runner the liquid extending and extend the gentle body extension jet pipe of jet pipe, make the more deep discharging area separately of two-phase, reduced to mix again.The feature of this structure be by fluid flow direction by axially changing into radially and circumferentially, having reduced to greatest extent the axial length of equipment, reduced occupation of land space.
The present invention is rational in infrastructure, modern design, and separative efficiency is high, long service life, floor space is little.The present invention adopts said structure and layout, makes axially " building block system " layout of whole separator, is convenient to detachable maintaining; On the basis that meets separator capacity, in structure, maximum feature is exactly increase as far as possible physical dimension radially and reduce axial physical dimension, has reduced separator floor space.As the shell separator of gas-liquid discharger, in enclosure interior, two-phase nozzle, separation rotor, sealing and lubricating arrangement are installed successively along axial direction, form the structure of a sealing.After the gas-liquid two-phase fluid entering from separator inlet separates with separation rotor through two-phase nozzle, separated gas phase and liquid phase are that the gas vent on housing top and the liquid outlet of bottom flow out from being arranged on gas-liquid discharger respectively.
