Abstract
The present invention discloses one kind of cascade cyclonic separator, and belongs to the field of liquid-solid and liquid-liquid separating apparatus. The cascade cyclonic separator consists of two serially connected cyclonic separator units, each of which consists of feeding cavity, guider, overflow pipe, barrel, cone, underflow pipe and other parts. The second cyclonic separator unit has its guider inlet connected directly to the underflow port of the first one, so that the under flow from the first cyclonic separator unit can enter the second one for secondary separation. The overflow of the second cyclonic separator unit is made to enter the cavity of the first one or led out through one additional pipe. The present invention has the advantages of high separating efficiency, compact structure, low cost, low power consumption and wide use.
Description
Technical field
The present invention relates to a kind of cascade cyclone separator, be applicable to solution-air, liquid-liquid, liquid-solid two-phase or multiphase separation of industries such as oil, chemical industry, environmental protection, medicine, food.
Background technology
Simple in structure, the convenient operating maintenance of hydrocyclone is a kind of equipment of extensive use in the gas-liquid-solid heterogeneous separation process.For improving separative efficiency, cyclone all carries out tandem to be used, and is divided into two kinds of forms of overflow series connection and underflow series connection.Series connection cyclone system architecture complexity, connecting line increases the drag losses of whole system.Especially in the limited place of arrangement space, can't normally use.
Summary of the invention
The purpose of this invention is to provide a kind of cascade cyclone separator, to solve the complex structure that prior art exists; Connecting line increases the drag losses of whole system; In the limited place of arrangement space, the problem that can't normally use.
The objective of the invention is to realize: comprise by feed cavity by following measure, overflow pipe, cylindrical shell, the first order cyclone that cone constitutes, feed cavity is connected with the upper end of cylindrical shell, the lower end of cylindrical shell is connected with the big opening end of cone, the coaxial feed cavity upper end that penetrates of overflow pipe is to cylindrical shell, it is characterized in that: on the same axis of the lower end of described one-level cyclone, be connected with second level cyclone, this second level cyclone comprises two stage diverters, the secondary overflow pipe, the secondary cylindrical shell, secondary cone and underflow pipe, the upper end of secondary cylindrical shell is connected with first order cyclone cone lower end osculum, two stage diverters are contained in the upper end of secondary cylindrical shell, the coaxial center of passing two stage diverters of secondary overflow pipe; The big opening end of secondary cone and osculum end respectively with top secondary cylindrical shell and below underflow pipe be connected.
Major advantage of the present invention is:
1. the separative efficiency height is specially adapted to the demanding place of underflow;
2. compact conformation, cost is lower, and bulk is less;
3. the guider fluid that will axially enter obtains fully to quicken before entering cyclone inside, reduces the existence of cyclone inner annular eddy current, and the symmetry of interior flow field and stability strengthen, and reduce the cyclone energy consumption;
4. simple in structure, have been widely used.

The specific embodiment
Referring to Fig. 1~Fig. 7, the present invention is made of first order cyclone A and second level cyclone B, is connected with second level cyclone B on the same axis of the lower end of described one-level cyclone A.Wherein:
First order cyclone A comprises feed cavity 1, overflow pipe 3, cylindrical shell 4, cone 5, and feed cavity 1 is connected with the upper end of cylindrical shell 4, and the lower end of cylindrical shell 4 is connected with the big opening end of cone 5 upper ends, and overflow pipe 3 coaxial feed cavity 1 upper ends that penetrate are to cylindrical shell 4.
Second level cyclone B comprises two stage diverters 7, secondary overflow pipe 8, secondary cylindrical shell 9, secondary cone 10 and underflow pipe 6, the upper end of secondary cylindrical shell 9 is connected with first order cyclone cone 5 lower end osculums, two stage diverters 7 are contained in the upper end of secondary cylindrical shell 9, the secondary overflow pipe 8 coaxial centers of passing two stage diverters 7; The big opening end of secondary cone 10 and osculum end respectively with top secondary cylindrical shell 9 and below underflow pipe 6 be connected.
The feed cavity 1 of described first order cyclone A has three kinds of structures: axial admission structure (referring to Fig. 1 and Fig. 6), cut-in type structure (referring to Fig. 2 and Fig. 3) or scroll casing type structure (referring to Fig. 4 and Fig. 5).
For the feed cavity 1 of axial admission structure, need guider 2 be installed in cylindrical shell 4, overflow pipe 3 passes the centre bore of guider 2.
Second level cyclone B is the axial admission structure, and its two stage diverter 7 is identical with first order corresponding structure with annexation between secondary overflow pipe 8 and the secondary cylindrical shell 9.
Guider 2 or 9 outer peripheral face and the inwall of cylindrical shell 4 or 9 closely cooperate, and the inner peripheral surface of guider overlaps with overflow pipe 3 or 8 external diameters.Outer peripheral face in guider 2 and 7 is provided with the runner C (referring to Fig. 7) that is formed by helicla flute or helical blade, is used to produce eddy flow.
And just do not need to install guider for the feed cavity 1 of cut-in type structure and scroll casing type structure, directly produce eddy flow by feed cavity 1.
Described secondary overflow pipe 8 also can be connected to outside the first order cone 5, as shown in Figure 6 by fairlead 11 in the upper end of this secondary overflow pipe 8 except the straight barrel structure of Fig. 1~shown in Figure 5.
During work, after mixed liquor carried out first separation by first order cyclone A, its underflow directly entered second level cyclone B and carries out secondary separation.Mixed liquor by the feed cavity 1 of first order cyclone A tangential or axially (along guider 2 runners) enter in the cylindrical shell 4, form the centrifugal force field of rotation at a high speed.Wherein heavy phase is descending in the cylindrical shell 4 and the cone 5 on the top, effect lower edge of centrifugal force field and axial compressive force, enter two stage diverters 7 of second level cyclone B, proceed to separate, remaining liq is discharged by underflow pipe 6, light overfall 3 discharges that then are pooled to top mutually by the secondary overfall 3 of bottom.
