Description
Technical field
The present invention relates to a kind of gas-liquid separation device, the band slug flow that especially relates to oil gas field special use in a kind of oil, the petrochemical industry system captures the manifold gas-liquid two-phase separator of function.
Background technology
In recent years, big oil gas field and oil gas structure have been found in succession in wide Haiti, beach district and western Gobi desert, desert area.But natural environmental condition is all very abominable, carries out the engineering construction difficulty on the spot, and required construction investment and administrative expenses are also high.Therefore, for efficient, safety, develop construction economically, the domestic multiphase flow conveying technology of greatly developing is delivered to oil, gas medium the downstream station by a pipeline mixing and handles.Field, downstream station adopts two kinds of schemes that upstream oil gas medium is received usually at present, a kind of is slug catcher, its advantage is that treating capacity is big, and adaptive capacity is strong, is usually used in the exploitation of larger hydrocarbon field, shortcoming then is the one-time investment height, easily up to ten million, in case gas field development program changes, easily cause the investment waste, floor space is big simultaneously, and is inapplicable for the station that landform is narrow; Another kind is conventional horizontal or vertical gravity gas-liquid separator, treating capacity is little and process range is narrower, can only satisfy the gas-liquid separation required precision in the certain limit, significantly increase owing to water content in the middle and later periods of gas field development, Chang Buneng satisfies the requirement of actual production operation.In addition when mixed transporting tube road pigging operation,, the slug flow that pigging produced has a strong impact on because also very easily causing the measuring equipment safety in the separating effect of conventional gas-liquid separator and downstream.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of manifold gas-liquid two-phase separator.
The technical solution adopted for the present invention to solve the technical problems is: a kind of manifold gas-liquid two-phase separator, comprise separator cylindrical shell and hydrops tube, be provided with the gas-liquid import in position near hydrops tube lower right side, the inlet manifold links to each other with gas-liquid, at separator cylindrical shell top right end separator outlet is set, described gas-liquid inlet manifold is divided into rising pipeline section and decline pipeline section, be provided with the air inlet branched pipe in gas-liquid inlet manifold's rising pipeline section latter end and decline pipeline section first section and stage casing, the air inlet branched pipe is above the separator cylindrical shell, the position parallel with the separator cylindrical shell converged the back and is connected with the gas phase inlet manifold, and gas phase inlet manifold inserts the separator cylindrical shell from separator cylindrical shell top; The liquid phase import is arranged on separator cylindrical shell left end.
The inclination angle scope of described gas-liquid inlet manifold's rising pipeline section be 30 the degree to 45 the degree, the inclination angle scope of decline pipeline section be-3 the degree to-15 the degree.In the air inlet branched pipe, be provided with every pendular ring.Position near the liquid phase import in the separator cylindrical shell is provided with cushioning fender, in the stage casing of separator cylindrical shell cowling panel is set.Be provided with interface of the level gauge at separator cylindrical shell and hydrops tube middle part.From left to right set gradually relief valve connection, manual atmospheric valve interface, water filling port, manhole and pressure sensor interface at separator cylindrical shell top.At described separator outlet wire-mesh mist extractor and isolated by filtration element are set.
Compared with prior art, good effect of the present invention is: intake method and the version of having improved conventional gas-liquid separator, by being set, the tilting reducing air inlet person in charge and multiple branch circuit riser carry out the pre-separation of gas-liquid gravity, change the two-stage Gravity Separation into by the one-level Gravity Separation, the fluid flow state and the gas liquid ratio that enter gas-liquid separator have been changed, can effectively capture managing the slug flow that forms in defeated and the pigging process, reach fast, safety, efficient effect of separating.Be in particular in: 1) solved the defective of gas-liquid separation when conventional gas-liquid separator can not satisfy pigging operation in the oil gas field production run process, reduced that slug flow is to the impact of equipment in the defeated and pigging process of pipe, the safety of equipment is swum at the protection station after the match; 2) compare with conventional slug catcher, greatly reduced construction investment and floor space, can be used as a kind of small-sized slug catcher and extensively apply in the station production and operation in oil, gas field; 3) equipment volume little, take up an area of less, the separative efficiency height, but skidization is widely used in the gathering station field in oil, gas field.
