The separator of gas (vapour) liquid is a process equipment commonly used in the industrial production such as oil and gas development, petrochemical industry, geothermal utilization, firepower and nuclear energy power generation.Vertical gas (vapour) liquid cyclone separator is little because of its compact conformation, occupation of land face, seldom heap advantages such as solid particle excreta is used widely.The flow regime in the operating efficiency of separator and the incoming flow pipeline and the particle of decentralized photo are that the size distribution of drop or bubble has much relations.Flow velocity in the incoming flow pipeline is higher, when throttling elements such as valve and elbow particularly nearby are installed when the separator inlet upstream, under the effect of strong mobile shearing force, the decentralized photo of heterogeneous fluid can be broken down into very little particle, make the separation fully of gas (vapour) liquid become difficult, the gas phase of separator or liquid phase outlet can be carried a large amount of drops or bubble secretly, and the efficient of separator greatly reduces.If can install a fairing additional in the upstream of main separator, earlier to gas (liquid) two-phase fluid slow down, rectification and pre-separation, and then enter main separator, the efficient of separator is greatly improved, and the overall dimension of separator is dwindled greatly.Yet in existing vertical gas (vapour) liquid isolation technics, the overwhelming majority does not just have fairing at all, has only utmost point individual design that the external fairing is arranged, but all exist complex structure, problem such as big takes up room.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, the special this programme that proposes---have vertical gas (vapour) the liquid cyclone separator of built-in spiral fairing, it has little, the compact conformation of taking up room, separative efficiency height, and the wide advantage of working range.
According to as above design, the feature of vertical gas (vapour) the liquid cyclone separator that has built-in spiral fairing that this programme proposed is: it is by the separator cylindrical shell, tangential inlet, the gas vent on top, the liquid outlet of lower end, the return duct of side, the sewage draining exit of bottom, the spiral fairing of inner barrel, tangential nozzle, gas phase channel, liquid film removes annular space, liquid collecting room, and toroidal membrane constitutes, the internal diameter of gas phase channel is greater than the external diameter of upper end gas outlet tube in the cylindrical shell, the gap that 5～10mm is arranged between two pipe ends, the neighboring of helicoid tightly is connected with the separator cylindrical shell, the inner rim of helicoid tightly is connected with the outer surface of gas phase channel, the inwall of the circular blast baffle of helicoid lower end and helicoid and separator cylindrical shell tightly is connected to form the tangential nozzle of tail end, upper end at helicoid tightly is connected with cylindrical shell and gas phase channel pipe with toroidal membrane, its position is lower than the backflow mouth of pipe, and the multiphase mixture inlet tube tangentially is connected with cylindrical shell, and be communicated with the helical duct of inside.
In this programme, in gas phase channel, can establish the cyclone of a spiral vane.
Adopt this programme can embody following superiority: 1. in this separator, constitute the helical duct of a downward-sloping square-section between helicoid and cylindrical shell and the gas phase channel, its sectional area is much larger than the sectional area of heterogeneous fluid-mixing inlet duct, make the speed of heterogeneous fluid-mixing reduce greatly, the particle of decentralized photo is that drop or bubble begin to merge, and under the double action of gravity and centrifugal force, forms laminar flow, reach the pre-separation effect of gas-liquid, promptly the first order is separated; 2. heterogeneous fluid is when helical duct moves to the lower end of passage, under the effect of deflector, suitably quicken, the tangential nozzle that forms by the inwall by deflector and spiral plate and cylindrical shell is tilted to down ejection then, form eddy flow at the separator inner chamber, gas (vapour) liquid is under the double action of gravity and centrifugal force, realized second level separation, promptly main gas (vapour) liquid separates; 3. at second level after separating, the liquid of separating flows into the liquid pool of cylindrical shell bottom downwards along barrel, and the gas (vapour) that is under the eddy flow state then upwards flows into gas phase channel from cylinder lumen mutually.In this process, because reducing of eddy flow radius, the swirl strength of gas phase in gas phase channel strengthens greatly, if air-flow also is entrained with drop, these drops will be thrown to vias inner walls by powerful centrifugal force, the liquid film that formation is upwards creeped along vias inner walls, these liquid films walk to when liquid film between gas passage and the gas vent shifts out annular space and overflow, and enter liquid collecting room, flow to the liquid pool of separator cylindrical shell bottom again through liquid return tube, separate thereby finish further demist, promptly the third level separates; 4. this separator has advantage simple in structure, that separative efficiency is high, it is little to take up room, working range is wide through probationary certificate.
