The specific embodiment
Hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can be combined mutually.
As shown in Figure 1, the three phase separator of the utility model embodiment, it comprises outer container 1, built-in receptacle 2 and differential pressure levelmeter 3, outer container 1 is closed container, the top of outer container 1 is connected with escape pipe 8, bottom is connected with outlet pipe 10, the middle part of outer container 1 or middle and lower part are connected with the feed pipe 4 that mixes phase, one end of differential pressure levelmeter 3 is connected with the bottom of outer container 1, the other end is connected with the top of outer container 1, and built-in receptacle 2 is fixed in outer container 1, and the upper end of built-in receptacle 2 is uncovered, lower end is connected with flowline 6, and flowline 6 is through the bottom of outer container 1.
Differential pressure levelmeter 3 is digitlization differential pressure levelmeter, and digitlization differential pressure levelmeter is provided with the sensor of measuring pressure reduction, and the display screen of digitlization differential pressure hydraulic ga(u)ge can show the pressure reduction of sensor measurement.
For charging is controlled, feed pipe 4 is provided with the first control valve 5.Flowline 6 is provided with fuel-displaced control of 7 pairs of flowlines 6 of the second control valve.Escape pipe 8 is provided with 9 pairs of capacities of the 3rd control valve and controls, to reach the object of controlling separator pressure.The 4th valve can also be set on outlet pipe 10.
Outer container 1 comprises the expanding reach 11 on top and the settling section 12 of bottom, and expanding reach 11 is connected up and down with settling section 12, and the cross section of described expanding reach 11 is greater than the cross section of settling section 12.The settling section 12 of expanding reach 11 and bottom can be for cylindric, and the cross section of expanding reach 11 is circular, and the cross section of described settling section 12 is circular, and the diameter of the cross section of described expanding reach 11 is greater than the diameter of the cross section of settling section 12.Wherein expanding reach 11 is mainly used in the separated of oil phase and gas phase, and settling section 12 is mainly used in the separated of oil phase and water.The cross section of expanding reach 11 is larger, and its main effect is to make oil, the gentle three-phase of water separated fully, has both avoided being with oil or oil mixed with water in water, has avoided again in gas with liquid phase.
Due to the sealing that is greater than oil phase of the density of water, when the upper gas pressure of expanding reach 11 hour, control the outlet of outlet pipe 10 lower than the upper edge of built-in receptacle 2, so just can guarantee that the water after layering can be from the outflow of outlet pipe 10.
The course of work of the three phase separator of the utility model embodiment is as follows:
Material (the mixing phase that contains oil-water-gas) enters middle part or the middle and lower part of outer container 1 from feed pipe 4, because the proportion of three-phase is different, upwards, water is to sedimentation for gas and oil, thereby realization is efficient separated.Gas phase, after expanding reach 11 and separation of oil, is discharged from the top of expanding reach 11, by the 3rd control valve 9 control system pressure; Oil phase enters built-in receptacle 2 along overflow from built-in receptacle 2, enters flowline 6 downwards, then from the bottom of outer container 1, draws and connects oil phase extraction pipeline.The differential pressure conditions detecting according to differential pressure levelmeter 3, controls the aperture of the second control valve 7, thereby controls oil phase liquid level in container; Water is arranged from three phase separator bottom extraction rear high-lying.This three phase separator can be realized continuous feed with separated.
Three phase separator liquid level is (X+Y), and discharge outlet height is A, if edge is H apart from three phase separator bottom level on built-in receptacle 2, oil phase (containing gas phase) proportion is d, and above-mentioned parameter meets following relational expression:
X+Y=H (formula 1)
X+dY=A (formula 2)
In above formula, H and A are three phase separator structural parameters, and d is by three phase separator feed properties parameter, and after above-mentioned parameter is determined, oil-water interfaces height X and oil phase height Y determine thereupon.Therefore,, for the fixing charging of component, in three phase separator, there is definite interfacial level and liquid level.
