Abstract
The helical pipe composite gas-liquid separator in vertical structure consists of a gas collecting part, a helical centrifugal separating part and a liquid collecting part mainly, and belongs to the field of fluid separating technology. The fluid entering to the helical pipe in the helical separating part to generates centrifugal acceleration, and under the common action of the centrifugal force and the gravitational force, the liquid with great density aggregates to the lower part of the pipeline while gas aggregates in the upper part before being exhausted through the upper holes in the helical pipe. Under the condition of lower gas content in the fluid or relatively small fluid flow rate, the fluid is separated mainly on the gas collecting part and the liquid collecting part mainly. The separator has simple structure, high separation effect, wide applicable flow rate range and content range, and other advantages.
Description
Technical field
The present invention relates to the gas-liquid separation device that a kind of gravity separates with the centrifugal principle compound action, especially be suitable for the gas-liquid separation of oil, petrochemical industry live crude, belong to the fluid separation techniques field.
Background technology
Oilfield surface engineering mainly is that the natural gas in the crude oil, water, oil, impurity are separated, and its first step is exactly to realize separating of natural gas and profit by gs-oil separator, and single well metering device also adopts the mode of measuring respectively after the Oil-gas Separation mostly.Be divided into gravity and centrifugal two kinds according to the principle separator.Traditional separator adopts the mode of Gravity Separation more, have that separating rate is slow, the separator volume big, separate in the oil of back gassiness gentle in oil-containing do not reach the desirable problem that requires.And cyclone gas-liquid separator utilizes centrifugal principle to carry out gas-liquid separation, separating rate is fast, effective, volume is little, in light weight, the equipment size that separates same oil tolerance can reach corresponding Gravity Separation equipment more than 1/4th, weight reaches more than 1/8th, so cyclone separator has good application potential.At present, cyclone separator mainly contains column cavity, single taper cavity, board-like, the rectangle spiral several types of eddy flow on planform, be mainly used in heterogeneous metering loop, and part is separated in the gas from liquid, form small-sized piece-rate system, constitute industrial circles such as combination trap.
At present, the research and the engineering application facet of gas-liquid cyclone separator also had the following disadvantages, the one, there is not complete Mechanics Calculation theoretical formula to can be used as the foundation of determining the cyclone separator physical dimension; The 2nd, the separator versatility is poor, and is poor to process conditions variation or medium rerum natura variation adaptive capacity.So, design fluid flow conditions change strong, the simple in structure size of less adaptability little, control easily that the gas-liquid cyclone separator is the research and development direction.
Summary of the invention
The objective of the invention is to design a kind of helical pipe composite gas and liquid separator based on gravity and centrifugal principle, make fluid in the helix tube runner, produce swirling motion, by centrifugal force gas is separated with liquid, for void fraction and the less industrial situations of bulk flow that adapts to, the design weight separating part carries out gas-liquid separation, thereby reach and dwindle the separator volume, enlarge the separator adaptive capacity, improve the purpose of gas-liquid separation effect.
Technical scheme of the present invention is, adopts vertical structure, totally is divided into three parts, and top is the gas collection part, and the centre is a spiral centrifugation part, and the bottom is a liquid collection section.Gas-liquid mixture enters the spiral separation part by inlet, in spiral coil, flow and produce centrifugal acceleration, assemble at centrifugal force and the big liquid downside outside pipeline of gravity acting in conjunction lower density, gas upside in pipeline is assembled, upper opening in helical pipe, isolated gas is discharged from tapping and is entered the gas collection part, and liquid enters the bottom liquid collection section along helix tube.When the fluid air content seldom or bulk flow hour, fluid mainly relies on separator top gas collection part and bottom liquid collection section to carry out Gravity Separation in that the spiral velocity in pipes is low when not reaching bigger centrifugal force.
Advantage of the present invention is, multi-circle spiral flow pipe runner produces forces helical flow to prolong the centrifugation time, the discharge that the upper side wall perforate has realized isolating gas in the helix tube, spiral separation has partly improved big flow, the gas content gas-liquid separation effect when higher relatively, has reduced the separator size; The less situation of low discharge and gas content mainly realizes gas-liquid separation by upper and lower Gravity Separation section, thereby has improved the accommodation of separator; Cyclone separator arrangement is simple in addition, realizes easily.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present invention
The specific embodiment
As shown in drawings, separator is made up of gas collection part 1, inlet 2, bottom drain 3, gas vent 4, spiral separation part 5, liquid collection section 6, liquid outlet 7, helix tube 8, and the 9th, helix tube cross section diagram.
Gas-liquid mixture enters spiral separation part 5 by inlet 2, in helix tube 8, flow and produce centrifugal acceleration, assemble at centrifugal force and the big liquid downside outside pipeline of gravity acting in conjunction lower density, gas upside in pipeline is assembled, and forms shape shown in helix tube cross section 9.Upper opening in helical pipe can be discharged gas, and the gas of discharging through helix tube 8 carries the vaporific drop of part and enters gas collection part 1, and it is slack-off suddenly that circulation area increases gas flow rate, and drop settles down under the gravity effect.Carry the part bubble through helix tube 8 row's liquid and enter liquid collection section 7, flow rate of liquid reduces, and the liquid collection section liquid level is controlled at certain height, and liquid stops the regular hours at liquid collection section 7, realizes that bubble floating separates.
