Description
Technical field
The utility model relates to a kind of cyclone separator that is used for gas solid separation.
Background technology
Because simple in structure, operating cost is low, to advantages such as condition of work are less demanding, cyclone separator is widely used in Air Pollution Control, the gas solid separation in sampling and the commercial Application.Separative efficiency and pressure drop are the important indicators of estimating the cyclone separator performance.In order to improve separative efficiency, people have carried out a large amount of work in the structure optimization of cyclone separator, have designed the cyclone separator of a lot of different structure forms.Three-dimensional Flow is very complicated in the cyclone separator, can be divided into downward outer eddy flow and the interior eddy flow that makes progress.Particle overcomes gas-flow resistance to cyclone separator wall motion under action of centrifugal force, then follow downward outer eddy flow motion and separate.Different inlet piping structures can cause the mode of gas-solid flow entering cyclone separator body different, thereby influences its separative efficiency.In the design of cyclone separator, in inlet duct, obtain enough acceleration if can not guarantee particle, perhaps particle gets into the cyclone separator body near the internal face and the upper wall surface of inlet duct, and then its separative efficiency will reduce.
The utility model content
The purpose of the utility model is: a kind of pair of access road cyclone separator is provided, changes the mode that air-flow and particle get into the cyclone separator body, thereby improve the separative efficiency of cyclone separator greatly.
The purpose of the utility model realizes through following technical proposals:
A kind of pair of access road cyclone separator; Comprise cyclone separator body and inlet duct thereof; Said inlet duct is by 90 ° of bend pipes of horizontal curvature, and the long straight pipeline that is communicated with the cyclone separator body is communicated with and constitutes, and long straight pipeline is divided into two parts by the dividing plate along the pipeline extension.
As optimal way, the radius of said 90 ° of bend pipes is not more than 1.5 with the width ratio, and the distance of said dividing plate distance straight pipeline outside wall surface and the ratio of duct width are 0.5～0.8.
As optimal way, said inlet duct cross section is circle or rectangle.
As optimal way, said long straight pipeline is towards the setting that has a down dip of cyclone separator body.
As optimal way, offer equal discharge orifice on the said dividing plate.
The effect of each parts is following in the utility model:
1 90 ° of bend pipe designs:
Inlet duct at first is provided with 90 ° of bend pipes.Gas-solid flow is after passing through 90 ° of bend pipes, and most particles will be gathered in the outside wall surface of inlet duct.Than the particle that gets into the cyclone separator body near the inlet duct internal face, the separative efficiency that gets into the particle of cyclone separator body near the inlet duct outside wall surface wants high, and this helps the raising of cyclone separator separative efficiency.The radius of 90 ° of bend pipes is more littler than (R/D) with width, and particle will be gathered in the outside wall surface of inlet duct more easily, and the R/D that therefore adopts is not more than 1.5.
The long straight pipeline design of 2 band dividing plates:
Particle through 90 ° of bend pipes after the overwhelming majority be gathered in the outside wall surface of inlet duct, even form cluster of grains, the speed of particle reduces, and is far from reaching the speed identical with air-flow.Just get into the cyclone separator body this moment like fruit granule, the reduction of separative efficiency will be cut down even might be caused to the raising of separative efficiency.Only increase the length of long straight pipeline, then particle can spread again in accelerator and move to the internal face of inlet duct.Therefore; Behind 90 ° of bend pipes, adopt the long straight pipeline of band dividing plate, both can guarantee that particle did not expand to the internal face of inlet duct, again can be so that particle obtains higher speed; And then get into the cyclone separator body, improve the separative efficiency of cyclone separator greatly.Dividing plate is excessive or too small all undesirable with the ratio (b/D) of duct width with the distance of long straight pipeline outside wall surface, between 0.5～0.8.Long straight pipeline length L should be tried one's best and made that greatly particle fully quickens.If long straight pipeline internal partition both sides airflow homogeneity differs bigger, can on dividing plate, offer equal discharge orifice.
The design that has a down dip of 3 long straight pipelines:
Long straight pipeline also can downward-sloping certain angle.Air-flow produces a horizontal component velocity and vertical component velocity in long straight pipeline, help increasing the component velocity under the cyclone separator body outward turning flow direction.Simultaneously, also give downward inertia of particle, move downward more easily and separatedly get off, thereby improve the separative efficiency of cyclone separator.
The beneficial effect of the utility model: the utility model adopt 90 ° of bend pipes with particle aggregation in the inlet duct outside wall surface; Owing to be provided with dividing plate in the long straight pipeline; Particle is near long straight pipeline outside wall surface motion and fully acceleration; Get into the cyclone separator body then, with the separative efficiency that improves cyclone separator greatly.Also can adopt the design that has a down dip with the duration straight pipeline, improve the mode that air-flow gets into the cyclone separator body, also help the raising of cyclone separator separative efficiency.
