Description
Technical field
The utility model relates to a kind of hydraulic centrifugal separator, particularly rotary vane type dynamic hydrocyclone, is mainly applicable to efficient separation or the gradation of solid liquid phase.
Background technology
Hydrocyclone is the one of centrifugal separation equipment, and it realizes two-phase or multiphase according to the density contrast between two-phase or multiphase to be under the influence of centrifugal force separated.Because the intensity of centrifugal force field is much bigger compared with gravitational field, therefore the separative efficiency of hydrocyclone force of gravity separation equipment is much bigger.From the application of First hydrocyclone patent in 1891 so far, the history of hydrocyclone has been pass by century more than 1.Nowadays, hydrocyclone is widely used in many industries such as mineral products, chemical industry, machinery, medicine, biology, food.
At present, hydrocyclone can be divided into two large classes on the whole: static hydrocyclone and dynamic hydrocyclone.Major part cyclone all belongs to static hydrocyclone, and its compact conformation, volume are little, quality is light, the feature such as installation, low, the long working life of maintenance cost that is easy to makes them be widely used.But when it carries out detached job, the kinetic energy of material places one's entire reliance upon pressure at inlet transformation of energy, and therefore the pressure loss is very large, cause the pressure reduction of medium in cyclone not enough and reduce the disposal ability of cyclone.If select entrance supercharging charging, except increasing energy consumption, also can aggravate the turbulent flow of cyclone inside, its separation accuracy is reduced.In addition, can reduce separative efficiency when treating capacity increases, also can reduce separative efficiency when material concentration is too high, be all the not enough aspect of static hydrocyclone.
Dynamic hydrocyclone in last century the eighties come out, mainly contain three kinds of common form: full ejector half, flow pattern of prewhirling and meet type, its common feature has one section of extraneous rotating mechanism driven.Under the rotary motion of rotating mechanism, the rotary speed of medium is improved, and the inlet pressure of medium does not need a large amount of to convert rotation function to, and its centrifugal force field just can be enhanced, thus pressure drop is reduced, and separative efficiency improves.And the centrifugal force field strengthened also can make discharge opeing smooth and easy, treating capacity increases.
But dynamic hydrocyclone still also exists some shortcomings: the outer rotaring tube of full ejector half hydrocyclone operationally can High Rotation Speed, the machine error of rotating cylinder can cause cyclone shockproofness excessive, field of swirler can be unstable because of vibrations, there is secondary blending phenomenon, affect the separation accuracy of cyclone.Flow pattern of prewhirling hydrocyclone only by the frictional force of segregation section cylinder inboard wall to improve the spin intensity of contour stealth, but its limited use, the efficiency that runner assembly transmits rotational is lower, therefore the enhancing effect of centrifugal force field not obvious.
Complex hydrocyclone is compared with full ejector half cyclone, and its shockproofness is lower, and inner flow field is relatively steady, and thus separating effect is better.Compared with flow pattern cyclone of prewhirling, the rotatory blade of compound inside better can transmit rotational, and what centrifugal force field was strengthened is more obvious, thus reaches better separating effect.Due to above various reasons, complex hydrocyclone is made to become current development trend.
Compound cyclone mainly with rotary blade hydrocyclone for representative, its composition of impeller two large divisions primarily of static cyclone shell and High Rotation Speed.This dynamic hydrocyclone has two large advantages: one is effectively suppress short-circuit flow, reduces coarse grained in overflow mixing.Two is the centrifugal sedimentation strengthening shell of column inner solid particulate phase, makes to be separated classification process in cyclone and is enhanced.Facts have proved, the separative efficiency of rotary blade hydrocyclone and disposal ability are obtained for raising to a certain degree.
Dynamic hydrocyclone, compared with static hydrocyclone, mainly strengthens the centrifugal force field of its contour stealth by rotating member, enhance the centrifugal sedimentation of liquid in contour stealth region in cyclone, but the centrifugal action of inward eddy is not effectively strengthened.Further, the mechanical oscillation of dynamic hydrocyclone cannot be avoided weakening, and the existence of mechanical oscillation will inevitably cause secondary blending phenomenon to a certain degree, thus reduce the separation accuracy of cyclone.The rotating member of dynamic hydrocyclone, when High Rotation Speed, can increase the turbulence intensity of cyclone internal flow, and overgenerous turbulent flow also can reduce the separation accuracy of cyclone.In addition, thick phenomenon is run in overflow also can produce adverse influence to the detached job of cyclone, although overflow that lower short-circuit flow causes is run thick to use rotary blade cyclone can effectively suppress to cover, the thick phenomenon of race that cyclone cone section underflow opening place causes because of air column turbulence is not eliminated.
