Description
Technical field
The present invention relates to a kind of fine grained Hydrocyclone for Silt Separation, belong to solid-liquid separation technique field.
Background technology
Hydrocyclone is a kind of separation equipment for being widely used general liquid non-homogeneous mixture, and basic principle is
By the liquid-liquid with certain density contrast, liquid-solid, liquid-gas etc., two-phase or multiphase mixture detaches under the action of the centrifugal, point
It occupies little space, and can operate continuously from efficient, separation equipment.Since the separation of two-phase or multiphase liquid mixture is each
The phenomenon that being all a kind of very universal in kind of industry, thus hydrocyclone chemical industry, oil, ore dressing, environmental protection, pharmacy, food,
All conglomeraties such as light industry, municipal wastewater processing, papermaking have boundless potential application market.Wherein solid-liquid hydraulic cyclone
The comparison of device development is early, has been applied to a variety of use such as desanding, clarification, concentration, gradation, the ore particle sorting of liquid at present
On the way, it is technically relatively ripe, but need in small size Solid-liquid Hydrocyclones and small grain size vortrap etc.
In technical further perfect；Liquid-liquid hydraulic cyclone then develops relatively late, and product variety is also relatively dull.
Certainly, the self-defect of hydrocyclone is mainly manifested in following several respects：
（1）Service condition is required high
Although the structure of various hydrocyclones is similar, separation principle is identical, its application is all needed according to processing medium
The difference of property, input concentration and flow etc. and specially design, and determine its operating condition.Their stalling characteristic is very
It is influenced in big degree by factors such as the pressure fed and the properties of mixture.
（2）Separation process, which is similarly, to be not completely separated from
Hydrocyclone is to be not completely separated from as other many separators.Equally it is solid- liquid separation, when particle diameter mistake
Hour is difficult to detach, but as long as rationally determining cut value, can meet the requirement of process stipulation completely.
（3）High speed rotary motion inside hydrocyclone can generate shearing-crushing to dispersed phase drop and be unfavorable for point
From the separation of medium is realized by under the action of vortex caused by liquid inside it high speed rotation in hydrocyclone
's.Liquid generates shearing force in high speed rotary motion, and this shearing force can make floccule body or coalescence agglomerate rupture, increase separation
Difficulty.
（4）High speed rotation can generate cyclone inner wall certain abrasion
In Solid-liquid Hydrocyclones, high speed rotation is solid particle inside it, and the inner wall of hydrocyclone may be produced
Raw serious abrasion, influences separating effect and service life.Such as when handling drilling mud with hydrocyclone, hard landwaste
Hydrocyclone inner wall can be greatly damaged, this was once a great problem in hydrocyclone use.Certainly, this problem is present
It can be improved by the development of novel wear resistant high hardness material.
Invention content
The technical problems to be solved by the invention：Not exclusively divide for service condition requirement Separation Processes Within Hydrrocyclones
Certain abrasion can be led to the problem of to cyclone inner wall from, high speed rotation, provides a kind of fine grained separation hydraulic cyclone
Device.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of fine grained Hydrocyclone for Silt Separation, including level-one cyclone and second cyclone, on the level-one cyclone
Side is cylindrical section, and lower section is conical section, is overflow pipe above level-one cyclone, ring pipe, ring pipe are provided on the outside of conical section
Inlet pipeline is connected, ring pipe offers inlet opening with conical section junction, and level-one cyclone is revolved by circulating line and two level
Stream device is connected, and second cyclone is identical with level-one hydrocyclone structure.
A kind of application process of fine grained Hydrocyclone for Silt Separation is：By liquid with set pressure at inlet duct into
Enter ring pipe, ring pipe offers inlet opening with conical section junction, and inlet opening enters along conical section inner wall tangential direction, liquid
After level-one cyclone conical section rotate, under the action of the centrifugal the larger microparticle of quality be gathered in level-one cyclone inner wall it is attached
Closely, and the smaller water of quality is gathered in the discharge of middle the heart channel of Hang-Shaoyin overflow pipe, the mixture after separation through entering ring pipe below conical section,
The repeated isolation in ring pipe and second cyclone, finally obtains separation product.
The level-one cyclone and second cyclone inner wall are smooth arc-shaped.
The ring pipe and conical section junction offer inlet opening, and inlet opening is along conical section inner wall tangential direction.
The ring pipe is provided with four groups of inlet openings with conical section junction.
The beneficial effects of the invention are as follows：
Enter second cyclone using two stages of hydrocyclones, liquid in the present invention after the separation of level-one flow cyclone, pass through
After two-stage separation, improve separative efficiency and quality, while ring pipe is set in the present invention on the outside of conical section, ring pipe and circular cone
Offer inlet opening at segment interface, inlet opening is along conical section inner wall tangential direction, when liquid enters ring pipe with certain pressure, leads to
Crossing inlet opening and entering after conical section can have that there are one initial velocities, and vortex is formed in cyclone, reaches centrifugation, is adopted
With ring pipe and inlet opening, reduce cyclone separation needed for the energy, reduce energy consumption, improve separative efficiency.
