The course of work
Oil-water mixture enters from liquid inlet 4, rapidly rotates under the action of rotatory 10 intracavitary, generates strong whirlpool
Stream, the mixed liquor then come push it to continue to move ahead, and movement is in scroll.It is detached from the oil water mixture high speed of rotatory 10
It rotates and continues to move, hence into big-taper-angle taper segment 12.Big-taper-angle taper segment 12 is connected with overflow segment 13.Hereafter it is centrifuged machine cavity
Internal diameter is gradually reduced, and rotation speed continues to increase, after biggish big-taper-angle taper segment 12, be transitioned into rapidly length it is larger,
The lesser overflow segment 13 of cone angle, herein, diameter change is slow, and rotary acceleration tends to mitigate.To realize water-oil separating.Water
In the past it brings out the mouth of a river 5 to go out, oil is discharged by hollow drive shaft radial hole 11 from the oil outlet 3 at top by hollow drive shaft 8
It goes.When liquid generates eddy motion, the pressure distribution of radial direction is differed, and boundary is higher, and nucleus is lower, thus to even
Drop in continuous phase liquid generates a centripetal difference force；Mixing liquid is different because inertia force acts in intracavitary rotary motion
Liquid phase particle generates different size of active force, therefore there are the effects of a centrifugal force for oil droplet；Oil droplet is transported in actual liquid
Dynamic, there are Stokes resistances caused by viscosity.
If water density ρw, oil droplet density ρ0, droplet diameter x drop is in flow field mainly by three power:
(1) the inertia force F that rotation generates1=ma；
It is (2) radial that there are centripetal force caused by barometric gradient
(3) the stoke resistance F that low-speed motion generates in viscous liquid due to drop3=3 π μ ux.
Under the effect of these three power, the big phase-water of density is thrown toward surrounding, and moves downward along wall surface, as underflow
Discharge；Small phase-the oil of density is to axe movement, and back overflow is discharged out of hollow drive shaft and in the intracavitary accumulation in front side, finally
Into fuel reserve tank, it is achieved in the separation rapidly and efficiently to grease, and by oily matter recycling and reusing.
