Description
Technical field
The present invention relates to a kind of separator, relate in particular to the cyclone separator that uses in a kind of Dual-Phrase Distribution of Gas olid or the stream-liquid two-phase flow.
Background technology
In the generation or technical process of industries such as chemical industry, metallurgy, the energy, environmental protection, often need the higher separator of separative efficiency, with solid particle in the capture Dual-Phrase Distribution of Gas olid or the drop in the stream-liquid two-phase flow.For example, in catalytic cracking, need utilize separator catalyst separation to be come out so that carry out recycle and reuse; In CFBB, separator is separated a large amount of high-temp solid materials from air-flow, send the combustion chamber back to, to keep the fast fluidized condition of combustion chamber, guarantee repeatedly recycling of fuel and desulfurizing agent, burn repeatedly and react, so the performance of separator will directly have influence on the overall performance of CFBB.
At present, the cyclone separator that uses in the prior art generally is made up of inducer, cylindrical shell, cone accelerating sections, central tube four parts.Usually, inducer is horizontal spiral case inlet, and two side planes shrink, and central tube arranges or arranged off-centre that for the geometirc symmetry axis line central tube is cylinder or cone.This kind cyclone separator is owing to fail to fully take into account the separating mechanism of cyclone separator, and its inducer structure can not be quickened fully for the particle of different-grain diameter, thereby makes separative efficiency be subjected to influence in various degree; The import horizontal gas flow is rotated down after entering cylindrical shell, flows to the discontinuous variation of structure in this process, has influenced the centrifugal force of particle, has reduced separative efficiency; The shape of central tube does not have to cooperate the shape of cylindrical shell and cone accelerating sections to make particle have bigger centrifugal force in the separator Lower Half, so separative efficiency awaits further raising.
Summary of the invention
The purpose of this invention is to provide a kind of cyclone separator, on the basis that takes into full account cyclonic separation mechanism, make full use of the influence of inducer, the particle of different-grain diameter is all quickened accordingly, therefore improve the separative efficiency of various size particles separative efficiency.
In order to realize above-mentioned purpose of the present invention, technical scheme of the present invention is as follows:
A kind of cyclone separator comprises cylindrical shell, and the central tube in the cylindrical shell entrance, cylindrical shell and the cone accelerating sections of cylindrical shell bottom is characterized in that: described cylindrical shell entrance is gone up plane, the lower plane that has a down dip, positive camber and negative camber by having a down dip and is constituted; Described central tube is made of the straight section on top, the contraction section of centre and the expansion segment of bottom, and arranges with respect to the centerline offset of cylindrical shell.
Technical characterictic of the present invention also is: the angle of throat α of throat's contraction section of described central tube
1For: 68 °＜α
1＜87 °, the angle of flare α of throat's expansion segment of described central tube
2For: 65 °＜α

The specific embodiment
Below in conjunction with accompanying drawing the concrete enforcement of the present invention and the course of work are further described:
Fig. 1 is the general structure schematic diagram of a kind of cyclone separator provided by the invention.This separator is by cylindrical shell 2, and cylindrical shell entrance 1 is arranged on central tube 3 and cone accelerating sections 4 compositions that are arranged on the cylindrical shell bottom in the cylindrical shell.Described cylindrical shell entrance is gone up plane 5, the lower plane 6 that has a down dip, positive camber 7 and negative camber 8 by having a down dip and is constituted; Central tube 3 is made of straight section 9, throat's contraction section 10 and throat's expansion segment 11 on top, and central tube 3 is arranged with respect to the centerline offset of cylindrical shell 2.Being central tube with respect to the horizontal eccentric distance a of cylindrical shell center line is: 0＜a＜0.01D, vertically eccentric distance b is: 0＜b＜0.01D (as shown in Figure 2).The central tube of biasing, the whole tangential velocity that helps air-flow is even, good separating effect.
