Description
Technical field
The utility model relates to a kind of high efficient gas and liquid separator, is mainly used in the gas-liquid separation of the natural gas well, the gas-liquid separation in oil field, the gas-liquid separation of petroleum refining industry.
Background technology
Gs-oil separator realizes that the prerequisite of gas-liquid separation is the density difference between gas-liquid; Realize through methods such as Gravity Separation, centrifugation, inertial separation; Conventional separators is usually by the primary separation element, compositions such as Gravity Separation space, and the efficient of gas-liquid separation is low; Bay publishing company publishes, and the 72nd page of introduction of " solution-air and liquid liquid separator " book that Maurice stewart and Ken Arnold collaborate has a kind of traditional gas-liquid separator.
A kind of existing horizontal type gas and liquid separator is by an import steering component; A gas separation space and a liquid separation space that is positioned at below, gas Disengagement zone are formed; The end edge region of separator; Be provided with a gaseous phase outlet, a liquid phase outlet simply is provided with one at the gaseous phase outlet place and catches the mist silk screen.
During work, original gas-liquid separation because the momentum of gas-liquid is different, can take place in gas-liquid charging bump steer element herein.Gas carries a part of liquid and gets into gas separation space, utilizes gravitational settling herein, carries out gas-liquid separation; Liquid gets into liquid displacement zone, and herein, the fraction free gas gets into gas separation space; At last, gas leaves separator from gaseous phase outlet, and liquid leaves separator from the liquid phase outlet.
The shortcoming of this separator is that the separation capacity is low, and equipment is heavy, takes up an area of big.
In the 27th page of offshore oil and gas engineering design application manual (second fascicle) that U.S. Checron Co. write in 1992, introduce a kind of centrifugal baffler, this baffler does not have cover plate, causes easily in the space of gas phase in the middle of eddy flow tube wall and wireway behind the centrifugal motion and flows into gas phase zone; Cause the short-circuit flow of gas, influence the separative efficiency of gas-liquid, in addition; This baffler is not provided with dividing plate; The effect of dividing plate has 2 points, and the one, gas is run into dividing plate when doing centrifugal motion; Gas-liquid promotes gas-liquid separation effect owing to the difference of inertia is separated; The 2nd, gas phase and liquid phase region separate, and can not cause carrying again of liquid.The utility model is provided with cover plate and dividing plate on built-in preseparator, promoted gas-liquid separation effect.
The patent No. 02267561.2 has been introduced another kind of horizontal type gas and liquid separator, and this separator is provided with a tubular type cyclone above the separator cylindrical shell, a mesh mist eliminator; A branch gas bag; A gas outlet, a liquid outlet divides between gas bag and the tubular type cyclone to be provided with air communicating pipe.
During work, the advanced tubular type cyclone of gas-liquid charging is under action of centrifugal force; Carry out the pre-separation of gas-liquid, most of gas gets into from communicating pipe and divides gas bag, carries out last gas-liquid separation; Gas after the separation leaves separator from the gas outlet; It is inner that liquid gets into separator, removes significant foam, finally leaves separator from the liquid outlet.
The advantage of this separator is to have utilized the tubular type cyclone to be the pre-separation member, can improve the efficient of gas-liquid separation, and shortcoming is, cyclone pipe has promoted the whole height of equipment, has increased operation easier, requirement that can not fine assurance gas outlet in the isolated gas phase.And this patent adopts is built-in eddy flow pre-separate device, can use the centrifugation of centrifugal force, has utilized the inner gas-phase space of separator again, has improved the effect of gas-liquid separation.
In the 28th page of offshore oil and gas engineering design application manual (second fascicle) that U.S. Checron Co. write in 1992, introduce a kind of arc plate blade filler; This filler is made up of the blade of concentric-ring pattern; Occupied whole gas-phase space, purpose is to remove in the gas-liquid mixed charging
Drop, the shortcoming of this filler is a smooth transition on the airflow direction, does not have obviously collision, and is only better than the effect of pure Gravity Separation.
