Technical field
The present invention relates to a kind of cyclone, more particularly to a kind of lateral feed type cyclone.
Background technology
Fluid or hydrocyclone are the device that a kind of utilization fluid or aqueous phase pressure produce eddy flow effect, its extensive use
In the separation of heterogeneous materials in fluid.Its general principle is：Fluid is empty to be tangential to cylindrical shell inner circle under a certain pressure
Chamber enters cyclone, produces high-speed rotational.In the presence of eddy flow field, the material grainses of different densities in fluid（Such as aqueous phase
Middle solid particle, liquid-phase particle or tiny oil droplets, bubble etc.）Relative to continuous phase such as aqueous phase or organic phase, will occur not Tongfang
To motion, the larger particle of such as density will move out along warp-wise, when the unhurried current layer for reaching cylindrical wall or V-arrangement wall or be detained
Just move downward, discharged by cyclone underflow opening during layer；As the less particle of density will inwardly be moved along warp direction or to
Central axial direction is moved, and is assembled in the whirlpool of axis centre formation, is then arranged by the overfall or siphon pipe of cyclone pipe
Go out, so reached the purpose of different densities material separation.But for traditional a fluid or hydrocyclone plant, liquid phase
Entrance is fixed, i.e., the ratio between cross-sectional area of liquid phase inlet area and cyclone is uncontrollable, causes the eddy flow of liquid phase
Flow velocity（R）With the axial movement of liquid phase（L）The ratio between（R/L）It is constant.Therefore, it exists and different system processing requirements is fitted
Answering property is poor, using the defect such as limited.
For tubular type or horizontal sliding flow reactor, theoretically, physics, the chemistry occurred in liquid phase between reaction substance is anti-
Should, what contact or collision between them were mainly occurred by the factor such as Brownian movement or Action of Gravity Field.Therefore, in some systems
Interior, this course of reaction dynamics is relatively slow or can not optimize.Have to improve reaction speed, optimization course of reaction, it is necessary to strengthen
Or optimization liquid phase（It is homogeneous or heterogeneous）Mixability, traditional method is to install mechanical agitation or the tube wall in tubular reactor
It is upper that fin or baffle plate are installed to realize, but the former adds equipment investment and operating cost, and the mixing intensity of the latter can not be at any time
Adjust or be difficult the defects such as prediction.
The content of the invention
