Abstract
The invention discloses a gas and liquid separator, which comprises a cylinder (51), a gas-phase and liquid-phase inlet (52), a gas outlet (54) and a liquid outlet (53). The gas-phase and liquid-phase inlet (52) and the liquid outlet (53) are arranged on the lower portion of the cylinder symmetrically and are tangent with the cylinder (51), and the gas outlet (54) is arranged at the top of the cylinder (51). By the cyclone separation technology, two-phase flow flows into the cylinder through the tangent inlet (52), and a strong cyclone is formed inside the cylinder, so that liquid with high density is thrown to a wall and discharged from the liquid outlet, and gas gathered at the center is exhausted from the gas outlet at the top. The gas-phase and liquid-phase inlet and the liquid outlet function equivalently, and accordingly the gas and liquid separator is convenient to operate and small in size.
Description
Technical field
The present invention relates to a kind of gas-liquid separator, relate in particular to a kind of gas-liquid cyclone separator, belong to gas-liquid cyclone separation process field.
Background technology
Existing cyclone separator has one or more two phase flow imports, a liquid outlet and a gas vent usually, and import is positioned at separator cylindrical shell top, and outlet is positioned at the cylindrical shell bottom.Must guarantee that the two phase flow fluid flows into from the import on top, flow out through the liquid outlet of separation back liquid from the bottom.According to retrieval to prior art; Find a kind of pipe column type gas-liquid cyclone separator; It has the pipe column type separator tube; Have gas-liquid mixture inlet tube and gas-liquid mixture inlet tube on pipe column type separator tube top and get into the pipe column type separator tube by the inclination tangential inlet, gas vent is positioned at pipe column type separator tube top, and liquid outlet is positioned at pipe column type separator tube bottom.See Chinese patent document number CN200920032330.3.When the system fluid flow direction changes, must rely on reversal valve to guarantee that fluid flows into from import, otherwise can't reach due separating effect, this makes the application of this gas-liquid separator become complicated.
Therefore, those skilled in the art is devoted to develop a kind of novel structure, and is easy to operate, the gas-liquid separator that separative efficiency is high.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly overcomes the defective of existing gas-liquid separator and a kind of Structure novel reasonable, easy to operate, separative efficiency is high, volume is little gas-liquid separator are provided.
For realizing above-mentioned purpose, the invention provides a kind of gas-liquid separator, comprising: cylindrical shell, gas-liquid two-phase inlet tube, gas outlet tube, liquid outlet tube; Wherein gas-liquid two-phase inlet and liquid outlet place the cylindrical shell bottom, with the tangent placement of cylindrical shell, and the position symmetry; Wherein gas vent places the cylindrical shell top.
In preferred embodiments of the present invention, wherein the gas-liquid two-phase inlet is suitable with the liquid outlet effect, can exchange use.
Described gas-liquid two-phase inlet is-50 °～50 ° with the angle of liquid outlet.
The distance of the center line of described gas vent and cylindrical shell center line is no more than 1/5 of barrel diameter.
The present invention utilizes cyclone separation process, and two phase flow flows into cylindrical shell through tangential inlet, forms by force in barrel and revolves, and makes the bigger liquid of density be thrown to wall and discharges from liquid outlet, and the gas that assemble at the center is got rid of from the gas vent at top.
The gas-liquid two-phase inlet is suitable with the liquid outlet effect.The direction that flows into separator when cold-producing medium changes, and promptly flows into from the primary liquid outlet, and when the two phase flow inlet was discharged liquid, gas-liquid separator also can reach identical separating effect.
The present invention's advantage compared with prior art comprises:
1. propose the gas-liquid separator of this structure first, in existing cyclone gas-liquid separator patent, do not had structure similarly;
2. because the gas-liquid two-phase inlet is suitable with the liquid outlet effect, can exchange use;
3. the gas-liquid separator of this structure is compared with existing separator, and volume has guaranteed its separative efficiency when reducing greatly;
4. need not other valves when flowing switching-over, make that application is very convenient;
5. when application of the present invention and refrigeration heat pump system, can a large amount of gas of bypass, can improve the heat exchanger heat exchange efficiency, reduce the pressure drop of heat exchanger;
6. gas-liquid separator is simple and reasonable, and interior flow field is orderly, and two phase flow separation process pressure drop is little.
Below will combine accompanying drawing that the technique effect of design of the present invention, concrete structure and generation is described further, to understand the object of the invention, characteristic and effect fully.

The specific embodiment
As shown in Figure 4, be a refrigeration system that comprises gas-liquid separator of the present invention, it is by compressor 10, condenser 20, and expansion valve 30, evaporimeter 40, gas-liquid separator 50, control valve 60 are formed.Working medium becomes the gaseous state of HTHP after overcompression in compressor 1, get into then to carry out condensation in the condenser 2, becomes supercooled state, passes through the throttling action of expansion valve 3 then, becomes gas-liquid two-phase and flows into gas-liquid separator 4.Working medium is separated in gas-liquid separator, and gas is discharged from gas vent, and liquid is discharged from liquid outlet.Liquid gets into evaporimeter, becomes overheated gas through heat absorption, mixes with gas from the gas-liquid separator gas vent, flows into compressor, accomplishes and circulates.
Like Fig. 2, shown in 3, gas-liquid separator of the present invention comprises: cylindrical shell 51, gas-liquid two-phase inlet 52, liquid outlet 53, gas vent 54.The cold-producing medium of gas-liquid two-phase flows into gas-liquid separator from gas-liquid two-phase 52 tangentials that enter the mouth, and in cylindrical shell 51, rotates along inwall.The bigger liquid of density is thrown to the near wall place under action of centrifugal force.The less gas of density accumulates in the cylindrical shell center to central motion.Liquid is discharged from liquid outlet along wall; Gas is discharged from gas vent.
In this example, because the cylindrical shell radius is little, centrifugal force is big, guarantees the high mass dryness fraction of gas vent.Two phase flow is at the barrel flow rule, and pressure drop is little.The liquid refrigerant passes through expansion valve is divided into liquids and gases through behind the gas-liquid separator.The saturated liquid inflow evaporator, the specific refrigerating effect of raising cold-producing medium.Under the constant situation of refrigerating capacity, the mass flow of the evaporimeter of flowing through reduces greatly, and the pressure drop of evaporimeter reduces.Saturated refrigerant liquid gets into evaporimeter, makes cold-producing medium become in the process of overheated gas through heat exchange, and two phase heat transfer zone increase, and the evaporimeter coefficient of heat transfer increases.Therefore under the situation of identical heat, the volume of evaporimeter reduces.
Second preferred embodiment of the present invention, as shown in Figure 5, the included angle A between gas-liquid two-phase inlet 52 and the liquid outlet 53 is set to less than 50 °.
The 3rd preferred embodiment of the present invention, as shown in Figure 6, the included angle A between gas-liquid two-phase inlet 52 and the liquid outlet 53 is set to 0 °, and the distance L of the center line of gas vent 54 and cylindrical shell 51 center lines is set to be no more than 1/5 of cylindrical shell 51 diameters.
More than describe preferred embodiment of the present invention in detail.The ordinary skill that should be appreciated that this area need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technical staff in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment.
