Abstract

The utility model discloses a screen structure for a cyclone separator. The screen structure comprises an inverted taper screen arranged at the bottom of an inner sleeve of the separator, wherein the top surface diameter of the screen is the same as the diameter of the inner sleeve, and the height of the screen is 1/ 10 to 9 / 10 times less than that of the separator. Compared with the prior art, the screen structure provided by the utility model has the following advantages and effects of simple structure and reasonable design, the disturbance of a flow field below the separator is weakened after being blocked by the screen, and the water mist generated by a swirl is difficultly discharged along with internal rotation updraft from the upper part, and thus the separation efficiency is effectively improved.

Description

A kind of mesh structure for cyclone separator
Technical field
The utility model relates to a kind of mesh structure, and the utility model relates in particular to a kind of mesh structure for cyclone separator.
Background technology
In the production process of petrochemicals, demist and the foam removal for example product carried out are processed, requirement to the gas-liquid separation technology is more and more higher, gas-liquid whirlwind separator has been proved to be one of the most effective equipment, its operation principle and to be used for the operation principle of cyclone separator of gas solid separation roughly the same.In running, the liquid phase material enters at a high speed separator from charging aperture 1 under pressure, gas-liquid mixture flows at water conservancy diversion leaf 5, and the form with drop or liquid film is thrown toward separator urceolus 3 inwalls under centrifugal action, along with liquid volume is more and more, liquid film is more and more thicker, and finally under Action of Gravity Field, liquid film flows to liquid-phase outlet 7 along the separator barrel.The air-flow of High Rotation Speed turns to inward eddy by outward turning circulation in the backspin process, the inner sleeve 4 and discharge from top gaseous phase outlet 2 of flowing through.Yet in existing gas-liquid separation device, eddy current can occur at the liquid-phase outlet near zone, and then cause the partially liq can be by Vapor Entrainment, and finally flow out from the top gaseous phase outlet, thereby the shadow gas-liquid separation effect is well separated this problem and screen cloth 6 is set above liquid-phase outlet.This patent increases screen designs on the existing structure basis, thereby effectively reduces air-flow entrained liquids quality, improves the separating effect of separator.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the existing gas-liquid whirlwind separator, and a kind of effective reduction air-flow entrained liquids quality is provided, and improves a kind of mesh structure for cyclone separator of the separating effect of separator.
The utility model is realized by the following technical programs:
A kind of mesh structure for cyclone separator, it comprises the turbination screen cloth that is installed in separator inner sleeve bottom, and the end face diameter of described screen cloth is consistent with the inner sleeve diameter, and the height of screen cloth is 1/10~9/10 times of separator height.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, the flow field of separator below disturbance is subjected to screen cloth to stop that rear disturbance weakens, and the mist by vortex arising is difficult to along with rotational gas flow in rising is discharged from the top outlet, thereby can the Effective Raise separative efficiency.
Description of drawings
Fig. 1 is that the mesh structure for cyclone separator of the present utility model is installed in the structural representation on the cyclone separator;
Fig. 2 is for having the mesh structure schematic diagram of diamond hole as a kind of embodiment of the present utility model surface.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, following instance is to explanation of the present utility model, but does not therefore limit the range of application of the utility model and technology.
A kind of mesh structure for cyclone separator of the present utility model as shown in drawings, it comprises the turbination screen cloth 6 that is installed in separator inner sleeve bottom, the end face diameter of screen cloth is consistent with the inner sleeve diameter, the height of screen cloth is 1/10~9/10 times of separator height, advantage in this scope is effectively to abolish secondary vortex flow in the separator, prevents that object being treated from being kicked up, taking out of separator by secondary.
The hole shape of described screen cloth is circular, square or rhombus, perforate bore dia or equivalent diameter are 0.1-50mm, advantage in this scope is: guarantee to capture under alap pressure drop the as far as possible object being treated of path grain, the whistle of avoiding simultaneously Air Flow to produce, wherein, equivalent diameter is d=2A/L, and A is hole area, and L is the hole girth.
Described screen cloth is a kind of in stainless steel mesh, carbon steel screen cloth, ceramic screen and the plastic mesh.
Coupling part between inner sleeve 4 and the urceolus 3 is water conservancy diversion leaf 5, gas-liquid two-phase is rotated mobile by the water conservancy diversion leaf in separator urceolus inboard, after the below urceolus shrank, gas phase changed inward eddy into by outer eddy flow and discharges from top gaseous phase outlet 2, and liquid phase then directly flows out from below leakage fluid dram 7.Screen cloth 6 is arranged on the inner sleeve below, avoids the formation of separator bottom eddy current, and stops partially liq to be carried secretly from the gaseous phase outlet discharge of separator top by the inward turning ascending air, and then improves separator.
Above embodiment is lifted by explanation the utility model, and protection domain of the present utility model is not limited to this.According to different separator disposal abilities, the height of its screen cloth, diameter, surperficial percent opening and open-celled structure also can have multiple arrangement.Being equal to that those skilled in the art do on the utility model basis substitutes and conversion, all within protection domain of the present utility model.
