As Fig. 2 has shown according to three-phase separating device 100 of the present utility model, comprise separation chamber 51 for holding oil, gas, water, be arranged on the unsteady oil-releasing mechanism 52 in separation chamber 51, and for being communicated with the inside and outside oil exit pipe 53 in separation chamber 51, the floating plate 54 that the oil-releasing mechanism 52 that floats comprises that communication type connects the cyclone cover 55 of oil exit pipe 53, is arranged on cyclone cover 55 tops and is fixedly connected with is with it formed for the radially inlet port 64 that liquid enters between cyclone cover 55 and floating plate 54.The effective separate space of this separator is large, makes separating effect better.Preferably, separation chamber 51 is set to column type.
As shown in Figure 3, floating plate 54 comprises the cylindrical floating plate main body 56 that is configured to hollow.Preferably, the circumferential lengths of floating plate main body 56 is not less than the height of separation chamber 51.It is the diameter that the girth of the circular cross-section of floating plate main body 56 is not less than the separation chamber 51 of column type.Thereby guaranteed mild feed liquor intensity, if avoided floating plate 54 too small, can cause gas to suck.
As shown in Figure 3, preferably, cyclone cover 55 is set to trumpet type, comprises horn mouth 58 and cyclone cover body 59.Horn mouth 58 comprises a plurality of swirl vanes 60 that protruding-type arranges.Preferably, swirl vane 60 extends at the inner surface of described horn mouth body 58, and its height reducing the direction at center gradually from horn mouth body 58 outers, as shown in Figure 4.Swirl vane 60 is fixedly connected with the second end of floating plate main body 56.Formed the inlet port 64 in order to guide crude oil radially to enter.Between floating plate main body 56 and horn mouth body 58, formed chamber 80 simultaneously.Preferably, in the outer of horn mouth 58, be set to level.Like this, under the effect of swirl vane 60, the crude oil on upper strata enters the inlet port 64 between floating plate 54 and cyclone cover 55 with radial direction, and enters into cyclone cover body 59 in the mode of eddy flow.Preferably, the equal diameters of the diameter of horn mouth 58 and floating plate 54.
The height of swirl vane 60 height of the outer place of horn mouth body 58 () is set to guarantee that speed that upper strata oil slick enters horn mouth body 58 is lower than 0.2m/s.The cylindrical diameter of cyclone cover body 59 is set to guarantee that the top-down flow control of liquid is at 0.5～1m/s(or Reynolds number 4000<RE<10000) in.
Floating plate 54 also comprises the cone 57 being fixedly connected with the second end of floating plate main body 56.For enough buoyancy is provided, guarantee that floating plate main body 56 second end floatings approach the crude oil liquid level 73 in separation chamber 51.Preferably, floating plate 54 can adopt proportion little, and the glass fiber reinforced plastic that antiseptic property is good is made.Cone 57 is arranged in chamber 80, and swirl vane 60 is not interfered with cone 57 occurrence positions.
Preferably, cyclone cover 55 is little by proportion, Corrosion Protection good, ganoid glass fiber reinforced plastic is manufactured.
Oil exit pipe 53 is connected with cyclone cover body 59 communication types.Preferably, for convenience of installing, cyclone cover body 59 and oil exit pipe 53 can be socketed, and as shown in Figure 3, one end of oil exit pipe 53 extend in cyclone cover body 59.At this, oil exit pipe 53 has also played the effect for cyclone cover body 59 location.Such as, cyclone cover body 59 and oil exit pipe 53 matched in clearance form slit 61 between cyclone cover body 59 and oil exit pipe 53, when swirl strength is low, avoid free water to scurry in oil exit pipe 53 from cyclone cover body 59 bottoms.
Oil-out 71 places at oil exit pipe 53 are fixedly installed eddy flow ozzle 62.Eddy flow ozzle 62 comprises the necking part 63 being configured to radially dwindling, and in eddy flow ozzle 62 view plane in Fig. 3, is the part of hyperbola form.This set, when oil exit pipe 53 starts oil extraction, is produced the pressure reduction of stronger ecto-entad by eddy flow ozzle 62, produce stronger eddy flow under the induction of cyclone cover 55 inward eddies.For guaranteeing enough strong eddy flow and suction force, preferably, the minimum place diameter of reducing diameter part 63 is 1/2～1/3 of cyclone cover diameter.
The top of eddy flow ozzle 62 is not less than oil-water interfaces 72.Guaranteed oil to be guided out outside separation chamber 51.
As shown in Figure 5, the oil-releasing mechanism 52 that floats also comprises and prevents that floating plate 54 is parallel to pasta direction and moves or rotate, and can control the limiting component 66 that the vertical pasta direction of floating plate 54 moves.Preferably, limiting component 66 comprises with holes 68 the connecting rod 67 being fixedly connected with floating plate 54 peripheries, backstay 69 that mate with hole 68 and that arrange perpendicular to liquid level, and the alignment pin 70 being fixedly connected with backstay 69, this alignment pin 70 is fixedly attached in separation chamber 51.Well known to those skilled in the art, it can be that backstay 69 passes hole 68 that so-called backstay 69 mates with hole 68, and under 68 restrictions of hole, can move but can not be parallel to pasta direction perpendicular to liquid level direction and move.
Convenient for installation and maintenance, the bottom of cyclone cover body 59 is 70～130mm apart from the distance of the diapire of separation chamber 51.Preferably, the bottom of cyclone cover body 59 is 100mm apart from the distance of the diapire of separation chamber 51.
During separator 100 operation, under the effect of swirl vane 60, upper strata crude oil enters inlet port 64 with radial direction, and enters in cyclone cover body 59 with cyclone mode.During oil-out 71 oil extraction, by eddy flow ozzle 62, produced the pressure reduction of stronger ecto-entad, under the induction of cyclone cover inward eddy, produce stronger eddy flow.Under the effect of centrifugal force, the interior centerline pressure of cyclone cover 55 diminishes, like this, density less, moisture lower oil slick in top just can suck cyclone cover 55 central areas, and discharge through oil exit pipe 53, and water is because the centrifugal force being subject to is larger, is difficult to enter into the oil exit pipe 53 at eddy flow center.In addition, the disperse water in oil slick is under cyclonic action, and part mutually collision coalescence forms oarse-grained free water, comes together in cyclone cover 55 inwalls and enter into the water layer of 51 bottoms, separation chamber under the effect of centrifugal force.Like this, eddy flow has just played oil suction, draining and separated triple role.
The foregoing is only preferred embodiment of the present utility model; but the utility model protection domain is not limited to this; any those skilled in the art is in the disclosed technical scope of the utility model; can easily change or change, and this change or change and all should be encompassed in protection domain of the present utility model within.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
