Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The present invention is a kind of experimental rig solution-air-liquid three phase separator, as shown in Figure 1, it comprises cylindrical shell, cylindrical shell comprises lower shell 1-1, the lower end of lower shell 1-1 is by being tightly connected with lower shrouding 1-5 and inner sleeve 2-1, the upper end of lower shell 1-1 is connected with the lower end of upper shell 1-2 by concentric reducer pipe fitting 1-3, and the upper end of upper shell 1-2 is connected with gaseous phase outlet 6 by upper cover 1-4.Have demister 4 near gaseous phase outlet 6 place in cylindrical shell, cylinder inboard wall upper feeding mouth 5 is provided with baffle plate 3-1 below position, and baffle plate 3-1 is connected with cylinder inboard wall by connecting plate 3-2.The inner sleeve 2-1 that cylindrical shell and upper end are enclosed within cylindrical shell is tightly connected, and the opening on inner sleeve 2-1 top is connected with taper pipe cap 2-4 by connector 2-3.The lower end of inner sleeve 2-1 is connected with first mouth of pipe 7, second mouth of pipe 8 by low head pipe cap 2-5.Second mouth of pipe 8 is arranged on the position near lower shell 1-1 lower end, and first mouth of pipe 7 is arranged on the lower end of low head pipe cap 2-5.3rd mouth of pipe 9 and the 4th mouth of pipe 10 are arranged at the bottom of cylindrical shell, and there is charging aperture 5 centre of cylindrical shell, and gaseous phase outlet 6 and the 5th mouth of pipe 11 are arranged at the top of cylindrical shell.5th mouth of pipe 11 is arranged on upper shell 1-2 top, and gaseous phase outlet 6 is arranged on the upper end of upper cover 1-4.Charging aperture 5, the 4th mouth of pipe 10, the 5th mouth of pipe 11 are arranged on the side of cylindrical shell, and the opposite side of cylindrical shell is provided with upper journal 12-1 and down journal 12-2.The present invention is fixed by upper journal 12-1, down journal 12-2.
Housing of the present invention by concentric reducer pipe fitting 1-3, the upper cover 1-4 between lower shell 1-1, upper shell 1-2, upper lower shell, lower shrouding 1-5 and for light liquid phase collect inner sleeve 2-1 and low head pipe cap 2-5 be welded to form, the pressure-containing member of constitution equipment.
Baffle plate 3-1 in upper shell 1-2 is arcuate structure, the bottom of baffle plate 3-1 is welded on upper shell 1-2 by connecting plate 3-2, gap between baffle plate 3-1 and cylindrical shell limits the flow direction of material, makes the liquid-liquid diphase in solution-air-liquid be settled down to Liquid liquid Separation section along barrel direction.In order to prevent gas from carrying secretly, improving separating effect, in upper shell 1-2, below gaseous phase outlet 6, demister 4 can be set.Upper shell 1-2 and baffle plate 3-1 and demister 4 form the gas-liquid separation section of three phase separator.
Liquid-liquid diphase is by the clearance space sedimentation separation between lower shell 1-1 and inner sleeve 2-1, heavier liquid deposition layering enters bottom gap, the breach 2-2 that lighter liquid phase leans against charging aperture side by inner sleeve 2-1 upper end overflows in inner sleeve 2-1, namely compared with the liquid storing tube of light liquid phase.In order to avoid the drop of segregation section directly falls into inner sleeve 2-1, inner sleeve 2-1 arranges taper pipe cap 2-4, is welded and fixed by connector 2-3.Lower shell 1-1, inner sleeve 2-1 and breach 2-2, taper pipe cap 2-4 constitute the Liquid liquid Separation section of three phase separator.
The present invention is arranged multiple input and output material and liquid level/interfacial meter mouth, the mouth of pipe (i.e. first mouth of pipe 7, the 4th mouth of pipe 10, the 5th mouth of pipe 11) is installed is formed by charging aperture 5, gaseous phase outlet 6, second mouth of pipe 8, the 3rd mouth of pipe 9, liquid level/interfacial meter.Liquid-liquid interface meter is installed by the 4th mouth of pipe 10, the 5th mouth of pipe 11, and heavy phase liquid material is discharged by the 3rd mouth of pipe 9.Light-phase liquid position meter can adopt oscillatory type or differential pressure type, and as adopted the former, installed by first mouth of pipe 7, light phase liquid material is discharged by second mouth of pipe 8; As adopted the latter, installed by second mouth of pipe 8, the 5th mouth of pipe 11, light phase liquid material is discharged by first mouth of pipe 7.
If in three phase separation process, gas phase amount is little, can simplify structure, saves gas-liquid separation section, is arranged on by charging aperture 5 in Liquid liquid Separation section, and as shown in Figure 2, this separator also can be used as Liquid liquid Separation device and uses.
The present invention is middle-size and small-size experimental rig, particularly little compared with light liquid phasor in solution-air-liquid three phase separation in micro-negative test device operating mode, achieves two liquid phase level stabilities controls, the continuous automatic discharge of two liquid phases.By the gap between design cylindrical shell and inner sleeve, can accomplish that under the prerequisite meeting liquid-liquid diphase layering liquid storage amount is minimum, even in a few minutes, make the sample of testing collection fresh, representative.And its cost is lower, about about 5,000 yuan, simple economy solve the insoluble difficulty run at present in experimental provision.
