Description
Technical field
The present invention relates to a kind of gas-liquid separation equipment, be specifically related to a kind of gas-liquid revolving wormgear separator, belong to Oil-gas Separation and gas dehydration technical field in the 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 the conventional separation volume is big, weight is big; The 2nd, the useful energy in the heterogeneous fluid is partially or completely consumed; The 3rd, when foam and emulsification generation, separate not thorough.Development along with China's oil and gas industry; The exploitation in special marine oil gas field is to the demand for development of oil and gas industry; Gs-oil separator develops to efficient, compact, energy-conservation direction from traditional gravity type; Many in the world oil companies to two mutually in the small-sized separator of recoverable energy pay special attention to, and drop into substantial contribution and research and develop.
At " TWO-PHASE REACTION TURBINE " (US4298311; 1981.11.3) etc. on the basis of patent, nineteen ninety-five, Hays has applied for the patent (US5385446 of " HYBRID TWO-PHASE TURBINE "; 1995.1.31), the notion of revolving wormgear separator has been proposed.
Pressure energy reforming unit---gas-liquid two-phase nozzle in the mixing two phase turbines in the Hays patent adopts the long-pending irregular runner in adjustable throat section to realize, though can realize Flow-rate adjustment to a certain degree, can not guarantee the efficient utilization of fluid pressure energy; Liquid film after the separation contacts with gas always, is unfavorable for reducing secondary and mixes; The separator gas blade adopts axial blade, and entire length is bigger, and floor space is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of gas-liquid revolving wormgear separator; Not only the separation of gas collection liquid, gas dehydration and shaft work are output in one; Also through 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 deficiency of prior art.
The basic principle of gas-liquid revolving wormgear separator of the present invention is to utilize two phase nozzles that the 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 that produces can be used for miscellaneous equipment such as pump, and separated gas and liquid pass through outlet drain separator separately.
A kind of gas-liquid revolving wormgear separator; Comprise rack-mount hollow housing; Via sealing and lubricating arrangement and be fixed in the rotating shaft in the housing; One end of this rotating shaft stretches out housing, and has the separation rotor that is positioned at housing inner chamber middle part to be fixed on the other end of rotating shaft, and an end adjacent with separation rotor of housing is provided with the gas-liquid two-phase nozzle; It is characterized in that above-mentioned separation rotor comprises is fixed on separator disk in the rotating shaft, that be provided with annular collecting tank and annular air collecting chamber on axially successively; Said collecting tank is connected with the separation cone, and described collecting tank and air collecting chamber are communicated with liquid reaction nozzle and gas reaction nozzle respectively, and is provided with the demarcation strip of annular between collecting tank and the air collecting chamber.
Mix again in order further to reduce to separate the back gas-liquid; Also can do further improvement to above-mentioned housing; The inner chamber middle part that specifically is housing is provided with the 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 collecting tank and air collecting chamber respectively.
The aforesaid liquid reaction nozzle also is connected with liquid conduits, thereby has guaranteed the utilization of the remaining kinetic energy of liquid of liquid reaction nozzle ejection and reduce to mix again.
The above-mentioned gas reaction nozzle also is connected with gas conduit, thereby has guaranteed the utilization of the remaining kinetic energy of gas of gas reaction nozzle ejection and reduce to mix again.
Separation rotor of the present invention is behind the inner surface of the separation cone of the high speed dual-phase jet impact separation rotor of two phase nozzles; Separation rotor rotation and completion gas-liquid separation; Under action of centrifugal force; Liquid flows into the collecting tank that separates in the wheel along the inner surface that separates cone, and gas has annular baffle to separate through getting into the air collecting chamber that separates wheel between collecting tank and the air collecting chamber.This structure at utmost reduced to separate the mixing again of back gas-liquid two-phase, minimized gas and carried secretly and the carrying of liquid, and improved separative efficiency.
Discharge through the gas reaction nozzle and the liquid reaction nozzle of separation rotor respectively after gas and the fluid separation applications, the present invention makes the deep-slotted chip breaker opposite with the separation rotor direction of rotation with liquid outlet on the separation rotor and gas exit passageway.This structure can utilize the high-head that is produced by centrifugal field to give fluid with the acceleration opposite with the separation rotor direction of rotation, and the angular momentum of the fluid that becomes a mandarin is reduced, thereby has reduced the value of the absolute velocity of fluid when leaving rotor.It one of mainly acts on 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 feasible absolute impact velocity that acts on the separate housings remains on very low numerical value, has minimized the erosion to shell.
Outlet at the arc runner connects the gentle body extension jet pipe of liquid prolongation jet pipe that prolongs, and makes two phases more go deep into discharging area separately, has reduced to mix again.The characteristics of this structure be with fluid flow direction by axially change into radially with circumferentially, reduced the axial length of equipment to greatest extent, reduced the 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 the dismounting maintenance; Satisfying on the basis of separator capacity, maximum characteristics are exactly to increase physical dimension radially as far as possible and reduce axial physical dimension on the structure, have reduced the separator floor space.As the shell separator of gas-liquid discharger, in enclosure interior two phase nozzles, separation rotor, sealing and lubricating arrangement are installed successively along axial direction, form the structure of a sealing.With after separation rotor separates, separated gas phase and liquid phase are respectively from being installed in the gas vent that the gas-liquid discharger is housing top and the liquid outlet outflow of bottom through two phase nozzles for the gas-liquid two-phase fluid that gets into from separator inlet.
