Description

A kind of gas-liquid cyclone separator with the hood-shaped exhaust pipe structure of awl

Technical field

The utility model relates to a kind of separation equipment, specifically is a kind of gas-liquid cyclone separator with the hood-shaped exhaust pipe structure of awl, is applicable to the separation of production industries such as oil, chemical industry, environmental protection, medicine, food to drop in the gas.

Background technology

Present widely used gas-liquid cyclone separator, its primary structure comprise feed cavity 1, blast pipe 3, cylindrical shell 4, cone 5 and discharging tube 6, and blast pipe 3 mostly is straight barrel structure (as shown in Figure 1) or funnel-shaped structure (as shown in Figure 2) greatly.For gas-liquid cyclone separator with Fig. 1, Fig. 2 tradition exhaust pipe structure, drop moves near exhaust pipe mouth in the outside wall surface of the acting in conjunction lower edge blast pipe 3 of surface tension, gravity and separator internal pressure field, form " lid is short-circuit flow down ", finally carried out separator, cause separative efficiency to descend by ascending air; And with the increase of separator inlet flow, the liquid measure that is carried out by ascending air also significantly increases.

Summary of the invention

The purpose of this utility model provides a kind of gas-liquid cyclone separator with the hood-shaped exhaust pipe structure of awl, and short-circuit flow is carried out separator by ascending air, the problem that causes separative efficiency to descend owing to cover down to solve that prior art exists.

The purpose of this utility model realizes by following measure: comprise feed cavity, blast pipe, cylindrical shell, cone and discharging tube, feed cavity is connected with the upper end of cylindrical shell, and the lower end of cylindrical shell is connected with the big opening end of cone, and the osculum end of cone is connected with discharging tube; The coaxial feed cavity upper end that penetrates of blast pipe is to cylindrical shell, and it is characterized in that: the bottom of described blast pipe is the horn mouth pyramidal structure.

The semi-cone angle scope of described horn mouth taper is 5 °～80 °.

Described feed cavity is axial-flow type, cut-in type or scroll casing type structure.The eddy flow guider is housed in the axial-flow type feed cavity.

Major advantage of the present utility model is:

1. separative efficiency height.Measuring, separative efficiency can improve more than 10%;

2. simple in structure, convenient processing and manufacture, cost is lower;

3. operating flexibility is big, and when inlet tolerance changed in a big way, separator all can be obtained higher separative efficiency.

4. be suitable for the gas-liquid cyclone separator of various structures, have been widely used.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model and work characteristics are described further.

Referring to Fig. 3～Fig. 6, basic structure of the present utility model comprises feed cavity 1, blast pipe 3, cylindrical shell 4, cone 5, discharging tube 6, 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, and the osculum end of cone 5 is connected with discharging tube 6.Blast pipe 3 coaxial feed cavity 1 upper ends that penetrate are to cylindrical shell 4, and the bottom of this blast pipe 3 is the horn mouth pyramidal structure.

Described feed cavity 1 is divided into scroll casing type structure (as shown in Figure 3), cut-in type structure (as shown in Figure 4) or axial arrangement (as shown in Figure 5).In the feed cavity 1 of axial arrangement shown in Figure 5, eddy flow guider 2 is housed, is provided with the runner C (referring to Fig. 6) that forms by helicla flute or helical blade at these guider 2 outer peripheral faces.

The utility model is in when work, for embodiment shown in Figure 5, contain liquid gas by feed cavity 1 in guider 2 enters cylindrical shell 4, by cylindrical shell 4 in, forms the centrifugal force field that a high speed is rotated to device 2.Wherein liquid phase is descending at the effect lower edge of centrifugal force field and axial compressive force cylindrical shell 4 and cone 5, discharges through discharging tube 6, and ascending air is discharged through blast pipe 3; Air-flows still are and rotatablely move in the blast pipe 3, wherein the residual liquid mist of part secondary separation to blast pipe inner conical surface under action of centrifugal force forms drop, drop is under surface tension and gravity effect, along conical surface reverse flow to the blast pipe end opening, under the effect of swirling eddy, got rid of again to separator barrel 4, final through discharging tube 6 discharges down.

And, just do not need guider 2 to produce eddy flow, but produce eddy flow by the feed cavity 1 of scroll casing type structure and cut-in type structure for Fig. 3 and embodiment shown in Figure 4.
