Description
Technical field
The present invention relates to a kind of centrifugal separating device of multi-phase ingredients, particularly cyclone-centrifuge combined liquid liquid separator, belongs to the isolation technics of processing a large amount of, high concentration, high viscosity or low interfacial tension mixed liquor.
Background technology
The hypergravity equipment that conventional liquid liquid separates has cyclone and centrifuge.
For high concentration, full-bodied liquid liquid mixture, as former wet goods, the mixed form usually wrapping up mutually with liquid-liquid exists, and simple sedimentation separation process, as centrifuge separates, wrap up in mutually system and reach separation requirement because being difficult to break liquid liquid, and, if this mixed liquor continuous phase viscosity is large, the easy emulsification of mixed liquor, and decentralized photo sedimentation migration resistance is large, be difficult to reach separation requirement by cyclonic separation.In addition, the apparent viscosity of this liquid liquid mixture is often also large than the viscosity of any phase wherein, fast in the decay of cyclone inward eddy, and centrifugal sedimentation driving force is not enough and affect separating effect.Moreover, for the liquid liquid mixture of high concentration, low interfacial tension, as the mixed liquor of cyclohexane, cyclohexanone and water, in cyclone, tend to be difficult to separate because turbulent flow, shear action make liquid group, the breakup of drop, emulsification.If the treating capacity of this mixed liquor is large, the equipment investment of centrifuge and operating cost are large.
Current domestic dynamic hydrocyclone machine adopts the mode of axial admission mostly, this feeding manner makes rotary drum L/D ratio value larger, floor space is large and separative efficiency is lower, exist secondary to become a mandarin simultaneously, the defect such as energy consumption is high, bearing life is low, complex structure, therefore Dynamic Hydrocyclone Separation Technology is not promoted use so far.
For this reason, the present invention, in conjunction with the advantage of cyclone and centrifuge, has proposed a kind of cyclone-centrifuge combined liquid liquid separator.
Summary of the invention
The object of the present invention is to provide a kind of cyclone-centrifuge combined liquid liquid separator, it is simple in structure, easy to use, can break liquid-liquid and wrap mutually mixed system, and avoid the emulsion of low interfacial tension liquid, improves separative efficiency, reduces costs.
For achieving the above object, the invention discloses a kind of cyclone-centrifuge combined liquid liquid separator, described cyclone-centrifuge combined liquid liquid separator is mainly made up of cyclone and centrifuge.Described cyclone is mainly made up of whirl cylinder, feed pipe and overflow pipe, and feed pipe tangentially inserts in whirl cylinder left end side, and overflow pipe is positioned at whirl cylinder left end coaxially overhanging with whirl cylinder, forms light liquid outlet.Described centrifuge is mainly made up of rotary drum, left bearing and right bearing.Bowl is mainly made up of rotary drum neck, rotary drum horn mouth, rotary drum large cylinder, rotary drum cone cylinder and rotary drum roundlet cylinder.The little cylinder of rotary drum and heavy liquid exit join, and form heavy liquid exit.Bowl is coaxial with cyclone, and bowl neck and whirl cylinder are with footpath and insert whirl cylinder certain distance, have radial seal between the two.Cyclone maintains static, and centrifuge is supported on left bearing and right bearing, by the belt pulley driven rotary that is positioned at its right-hand member.
The operation principle of this device is as follows, and liquid liquid mixed liquor tangentially enters cyclone through charging aperture with certain speed, and produces eddy flow.Due to the mobile semi-free vortex that is mainly in cyclone, there is turbulent flow, shear property, liquid liquid mutually parcel system is broken, and is issued to the object of pre-separation at centrifugal action.Subsequently, mixed liquor enters centrifuge also further by the density contrast sedimentation layering of phase by neck and the horn mouth of rotary drum.Because turbulence intensity in centrifuge weakens, shearing force reduces, and drop can be not broken again.Underflow opening is moved and flowed to heavy phase to wall under the effect of centrifugal force, thereby discharge from underflow opening, and light liquid is assembled and flows to vertically cyclone at the effect Xia Xiang center of centrifugal force mutually, finally discharges from overfall.
Usefulness of the present invention is: 1) the mutual inclusion of liquid liquid system under the efficient separation of high-concentration of this device energy.2) this apparatus structure is simply compact, working stability.3) this plant energy consumption is little, long working life.

Detailed description of the invention
With reference to Fig. 1, Fig. 2, this cyclone-centrifuge combined liquid liquid separator is mainly made up of cyclone 21 and centrifuge 9.The main body of described cyclone 21 is cylinder, and side is provided with cyclone charging aperture 3, and this cyclone charging aperture 3 is tangent with whirl cylinder 22, and cyclone overfall 1 is positioned at whirl cylinder 22 left ends coaxially overhanging with whirl cylinder 22.Described centrifuge 9 is mainly made up of left bearing 6, rotary drum neck 20, rotary drum horn mouth 7, rotary drum large cylinder 8, rotary drum cone cylinder 10, rotary drum roundlet cylinder 18 and right bearing 12.Rotary drum roundlet cylinder 18 right-hand members are seperator heavy-fluid underflow opening 16.Centrifuge 9 coaxially makes whole apparatus structure simple with cyclone 21, becomes a mandarin without secondary, and mixed liquor once steadily enters rotary drum, reduce the sudden contraction sudden expansion of liquid flow, flowed steadily, and then reduce turbulent flow, reduce the emulsification pretreatment to material, flow losses are less simultaneously, play energy-conservation effect.Bowl neck 20 and whirl cylinder 22 are with footpath and insert whirl cylinder 22 certain distances, there is radial seal 5 between the two, the Main Function of seal 5 is to prevent that mixed liquor from flowing out from the gap location of cyclone 21 and centrifuge 9 coupling parts, thereby plays the effect of sealing.Cyclone 21 maintains static, centrifuge 9 is supported on left bearing 6 and right bearing 12, drive rotary drum roundlet cylinder 18 to rotate by the belt pulley 13 that is positioned at its right-hand member, employing rotary drum cone end small end is that the benefit of rotary drum roundlet cylinder 18 place's input power modes is that axial dimension is little, compact conformation, stable, aspect supporting, the radial dimension of right bearing 12 is little, thereby make right bearing 12 rotational line speed little, long working life.
With reference to Fig. 1, Fig. 2, liquid liquid mixed liquor with certain speed from cyclone charging aperture 3 enters cyclone-centrifuge combined liquid liquid separator, at the interior generation eddy flow of cyclone 21.Due to the interior mobile turbulent flow of cyclone 21, shear action, liquid liquid phase mutually parcel system is broken, and be issued to pre-separation in the effect of centrifugal force, enter centrifuge 9 by rotary drum neck 20 and rotary drum horn mouth 7 subsequently, now turbulence intensity weakens, shearing force reduces, mixed liquor is further pressed density stratification under higher centrifugal action, heavy-fluid in opposite directions rotary drum wall is moved and is flowed out to seperator heavy-fluid underflow opening 16 along rotary drum cone wall, and light liquid Xiang Zexiang center is assembled and in axial direction flowed out by cyclone overfall 1.
Described cyclone-centrifuge combined liquid liquid separator is horizontal, can be also vertical.
Above-described embodiment only for exemplary purposes, is not intended to limit the scope of patent of the present invention.Within those skilled in the art have done according to teachings herein any amendment that does not exceed patent object of the present invention and intention or distortion are included in the application's scope.The scope of patent of the present invention is limited by claim.
