Abstract
The utility model discloses a tubular dynamic centrifugal separator, which is suitable for separating oil and water or separating two mutually insoluble feed liquids in the petroleum, chemical and environmental protection industries. It is by the hollow tube, control end shaft, bearing frame, cone, nozzle, bipyramid play oil pipe, feed liquor pipe, outlet pipe etc. and constitute because make full use of fluid jet and rotational speed stack principle and free vortex (or half free vortex) hydraulic effect to the runner is arranged to the theory, forms a separation oil reservoir in the hollow tube, consequently the utility model discloses it has higher separation efficiency than with the ordinary tubular centrifuge of rotational speed.
Description
The utility model relates to a kind of tubular type liquid/centrifuge of fluid, is applicable to that water-oil separating is used in oil, chemical industry, the environmental protection industry (epi), belongs to centrifugation machinery technical field.
The supercentrifuge that existing tubular type centrifugal separator is made up of a joint straight tube and interior dress blade relies on the blade of rotation at a high speed to make feed liquid produce forced vortex in the separation process.Though this seperator has very strong separating power, treating capacity is little, and because of the high speed rotating operation, in use easily produces fault, influences the service life of complete machine.
The purpose of this utility model is will provide to carry out liquid/liquid separation, the particularly dynamic centrifugal separator of the coil formula of water-oil separating in a kind of suitable oil, chemical industry, the environmental protection industry (epi).
The purpose of this utility model is achieved in that dynamic centrifugal separator comprises hollow pipe, feed tube, outlet pipe, bearing, bearing block, it is characterized in that seperator is provided with cone, the bipyramid flowline of band nozzle, hollow pipe is provided with large and small head, major part is a conical pipe, cone is arranged in the conical pipe of hollow pipe, the bipyramid flowline is arranged on the microcephaly of hollow pipe, and the outer wall of hollow pipe is provided with and is used to drive the belt grooves that hollow pipe rotates.The injection direction of the nozzle on the said cone is consistent with the direction of rotation of hollow pipe.Constitute the descending ring taper necking down of liquid stream radius of turn between the conical pipe of hollow pipe and the cone that sets within it.The bipyramid end of bipyramid flowline is towards the separation oil storage chamber that is made of hollow pipe, cone and bipyramid flowline.When feed liquid enters the separation oil storage chamber from feed tube, at first by the nozzle on the cone, make feed liquid along forming an angle with tangential direction, spray into ring taper necking down.The feed liquid injection direction is consistent with the direction of rotation of hollow pipe.When feed liquid flowed to the microcephaly by the major part of hollow pipe, its rotation tangential velocity diminished with the flow field radius and increases, and liquid stream is because free vortex, semi-free vortex effect, and produced very high separating power.Oil after the separation stops at the place, axle center that separates oil storage chamber and flows out by the bipyramid flowline, and the water after separating flows out through outlet pipe by the outer circular passage of the fuel-displaced tube wall of bipyramid.
The utility model novel and reasonable structure is manufactured easily, and cost is low, and is easy for operation.Separation oil storage chamber in the hollow pipe has the effect of liquid stream, store oil, separation.Liquid stream in the hollow pipe advances with the rotation spiral of hollow pipe, is convenient to the separation of weight liquid.Isolated light phase thing accumulates in the near axis that separates oil storage chamber from feed liquid, forms a storage area, flows out from the bipyramid flowline that is arranged on the hollow pipe microcephaly.And isolated heavy phase thing accumulates in a water retention zone of tube wall formation of separating oil storage chamber from feed liquid, and flow out through outlet pipe the circular passage outside the fuel-displaced tube wall of bipyramid.This machine separated light, heavy-fluid time of staying in separating oil storage chamber is long, improves oil-water separation, hollow pipe utilization rate height has improved the separating treatment amount, owing to hollow pipe directly rotates, simple in structure, fault is few.
Accompanying drawing is a structural representation of the present utility model, 1 feed tube, 2 sealings, 3 bearing blocks, 4 bearings, 5 bearing caps, 6 end axles, 7 nozzles, 8 hollow pipes, 9 bipyramid flowlines, 10 cones, 11 outlet pipes, 12 belt grooves among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
Two ends with hollow pipe of concentric reducer connect the hollow end axle respectively, and the major part of hollow pipe is a conical pipe, and cone is arranged in the conical pipe, and two (or several) spiral nozzles are set on the cone, and the bipyramid flowline is arranged on the microcephaly of hollow pipe.The bipyramid flowline is nested with in the hollow end axle, constitutes the annular exhalant canal that communicates with outlet pipe between bipyramid flowline and the hollow end axle.Hollow pipe is bearing in respectively on bearing and the bearing block by the hollow end axle, and bearing is compressed by bearing cap.Be provided with by power set on the outer wall of the conical pipe of hollow pipe and drive the V belt groove that hollow pipe rotates, between end axle and feed tube, the outlet pipe sealing device is set by bead apex.Form water-oil separating and oil storage chamber between cone, hollow pipe, the bipyramid flowline three.Form a ring cone space (ring taper necking down) between the conical pipe of cone and hollow pipe.
When processed oil-polluted water or two kinds of immiscible liquid feed liquids enter seperator by import by nozzle along becoming the β angle, with speed V with tangential direction
1Spray into the ring conical cavity, this moment, liquid flowed absolute velocity V
GreatlyBe the tangential rotary speed V in nozzle place
2Spray tangential velocity V with liquid
1Cos β sum.
The liquid of the rotation ring awl chamber of flowing through enters when separating oil storage chamber, because free vortex (or semi-free vortex) effect is being separated speed Vr=V on the store oil space radius γ
Greatly(γ greatly/γ)
n(n=0.5～1) maximum speed district is at 1/3R
LittleThe place, separating factor can reach 10
4More than, the isolated near axis that separates oil storage chamber that gently accumulates in mutually from feed liquid, form a storage area, control oil-out flow size, the oil that assurance is separated stops the regular hour in the storage area, increase oil-water separation, purify waste water and flow out from outlet pipe, reach two kinds of fluid separation applications with certain weight proportion difference by the circular passage.
A kind of advanced development 15m of the present utility model
3/ h seperator is through the reality test, when the profit density contrast is 0.13g/cm
3, droplet diameter＞10 μ m, oil content 0.1～0.4% o'clock, water-oil separating efficient＞96%, efficient＞76% when separating emulsion, when more than testing, inlet pressure is 0.2～0.32Mpa, every m
