Abstract

The utility model discloses a multi-column-cone combining type liquid-liquid separating swirler which is composed of a plurality of column sections and conic sections which are alternately connected with each other and a tail pipe. The utility model has the advantages of that: the flowing loss in the swirler is decreased, and the energy consumption is reduced; the processing is less difficult, and the processing precision is easier to ensure. The utility model is applicable to the liquid-solid and liquid-liquid separations field in industries such as petroleum, chemical engineering, environmental protection, medicine, and foods.

Description

Poly-column-awl combined type liquid-liquid separates uses cyclone

Technical field

The utility model is applicable to liquid-liquid separation hydrocyclone of industries such as oil, chemical industry, environmental protection, medicine, food.

Background technology

Liquid-liquid separates and generally is made up of charging aperture, overflow pipe, cylinder, cone and tail pipe etc. with hydrocyclone, and wherein cone structure is generally single awl or bipyramid form.It is generally acknowledged, its main centrifugation of the cone of cyclone, for the flow field situation of improving cyclone inside, improve its separative efficiency, the optimization of cone structure is modified into the important research target into people.Developed at present have third hand tap, liquid-liquid of cone form such as curved surface awl separates and uses hydrocyclone.

But the following problems of cone structure form ubiquity such as single awl, bipyramid, third hand tap and curved surface awl:

1. taper hole is long, the conical surface is too complicated, and feasible processing, assembly difficulty with cyclone of this class formation increases, and the assembly precision of joining place is difficult to guarantee between the cone, and the processing charges of cyclone also can increase therefore and to some extent.

2. cone changes when remedying the inner rotation function consumption of cyclone, strengthening the centrifugation field of force continuously, has increased unnecessary turbulence energy consumption, has improved the shear action of fluid to dispersed phase drop.

Summary of the invention

The purpose of this utility model is to provide the poly-column-awl combined type liquid that a kind of processing technology is simple, easy to assembly and assembly precision guarantees easily, separative efficiency is high-liquid to separate and uses cyclone.

Order of the present utility model is realized by following measure.

The said Liquid-Liquid Separation Hydrocyclone of the utility model be is characterized in that by charging aperture 1, overflow pipe 2, cylinder 3, cone 4, cylinder 5, cone 6, tail pipe 7: described hydrocyclone structure is connected and composed at interval by at least 2 straight pilaster bodies and 2 cones at least; The tail pipe end of Liquid-Liquid Separation Hydrocyclone can connect a cone; The cone angle that connects cone at interval is identical or inequality.

Description of drawings

Fig. 1 is the structural representation of the cyclone of tail pipe band one cone that proposes according to the utility model;

Fig. 2 is that the tail pipe that proposes according to the utility model is not with the hydrocyclone structure schematic diagram of cone.

The specific embodiment

Below in conjunction with drawings and Examples structure of the present utility model and work characteristics are further described:

As shown in Figure 1 and Figure 2, the utility model is connected successively by charging aperture 1, overflow pipe 2, cylinder 3, cone 4, cylinder 5, cone 6, tail pipe 7 etc. and constitutes.During work, mixed liquor enters cyclone by charging aperture 1, forms a centrifugal force field of rotating at a high speed in cyclone.Wherein heavy is descending at the effect lower edge of centrifugal force field and axial compressive force cylinder 3, cone 4, cylinder 5, cone 6, discharges via tail pipe 7, cone 8 (Fig. 1), perhaps directly discharges (Fig. 2) via tail pipe 7, and lightweight is then discharged by overflow pipe 2 mutually.

The design of this multistage cylinder has reduced the turbulence intensity of interior flow field, stablizes separated space for heterogeneous fluid provides multistage; The multistage taper designs makes internal flow anglec of rotation momentum in time to obtain to replenish, and improves swirl strength, has strengthened separation process.

Because liquid-liquid rotational flow separation device tail pipe is longer, center lightweight phase fluid column tail end spin intensity significantly weakens, the angular momentum deficiency, usually " wagging the tail " phenomenon occurs, influences separative efficiency.The terminal awl section that increases of tail pipe can remedy angular momentum, stable center lightweight phase fluid column, thereby improves separative efficiency.

Major advantage of the present utility model is:

1. cone is shorter, processing, installs simple and conveniently, and post cone joining place assembly precision guarantees easily.

2. reduced owing to cone changes the part turbulence energy consumption that produces continuously, the cyclone energy consumption decreases.

3. the poly-column-awl combination is so that rotational flow field is stable in the cyclone inside, balanced energy consumption distributes, the shearing of fluid Fragmentation reduces, and separative efficiency improves.
