Description
Technical field
The present invention relates to a kind of vertical centripetal coagulation type seperator of dome and its separation method, belong to heterogeneous liquid-liquid thing
System separates equipment and applied technical field.
Background technology
Centrifugal separation technology is a kind of developing history technology more remote, wherein some centrifuges are by by means of its turn
Rouse the centrifugal force produced by high-speed rotation to realize the technology of separation or the concentration of material, be usually used in separating two or more density not
With but mutual exclusive suspension or emulsion, such as：Solid-liquid, liquid liquid, the separation process of solid-liquid liquid.
Centrifugal separation technology is included：Centrifugal sedimentation and centrifugation etc..
Because the equipment such as centrifuge can produce at a relatively high angular velocity of rotation, centrifugal force is set to be much larger than gravity, then fluid
Suspension in solution is convenient to Precipitation, and because the centrifugal force suffered by the different material of proportion is different, so as to settle
Speed is different, and the material that proportion can be made different reaches separation.
Centrifuge is exactly that rotation produces powerful centrifugal force to separate heterogeneous thing system at a high speed using rotor（Liquid liquid, liquid is solid,
Liquid-liquid-solid）A kind of universal machine.It is mainly used in separating the solid particle in suspension and liquid；Or by emulsion two
Density difference is planted, but immiscible liquid is separated, for example, cream is isolated from milk.
Centrifuge has a rotating cylinder rotated at a high speed around the main shaft cylinder of oneself, commonly referred to as rotary drum.Generally by electricity
Motivation drives, and compared with other separation machineries, centrifuge typically has separative efficiency high, small volume, sealed reliable, auxiliary device
Few the advantages of, thus it is widely used in chemical industry, oil, light industry, medicine, food, weaving, metallurgy, coal, ore dressing, ship, army
The every field such as work and environmental protection.
Into after 20th century, with the development that oil is comprehensively utilized, it is desirable to water, solid impurity, tarry matters etc.
Remove, to make heavy oil be used as fuel oil, succeeded in developing the dish-style piston slag draining and separating machine of automatic discharge the fifties, arrive
Develop into perfect series of products the sixties.The need for developing with modern age environmental protection, the disposal of three wastes, for industrial wastewater and
The requirement of sludge dewatering treatment is all very high, therefore under promoting horizontal spiral discharge sedimentation centrifuge, disk centrifuge and 3-foot
Portion's discharging sedimentation centrifuge has the development of further development, particularly horizontal type screw settling centrifuge and disk centrifuge outstanding
For rapid.
The separation of heterogeneous liquid-liquid thing system occupies an important position in oil and chemical industry, is technology ensuring, equipment guarantor
The indispensable key unit operations such as shield, fluid purification, liquids recovery and finished product purification.Recently as China's oil refining
How the expansion of system and oil downstream product process scale, more economically effectively realize the separation of heterogeneous liquid-liquid two-phase,
Reducing energy consumption, improves efficiency and ensures safety and increasingly paid close attention to by people.
Due to the particularity of some industries, required fluid cleanliness factor has strict limitation, but then, due to
Fluid property in itself, causes to be dissolved in the useless fluid of some of which being very difficult to remove, such as all kinds of oil water mixtures.
Under constant pressure, the relation that the content of kerosene, gasoline and bavin dissolved water in fuel is varied with temperature is fixed.
Kerosene can absorb moisture from air, reach dissolution equilibrium, but when the temperature decreases, just have Free water generation, so repeatedly
Carry out.Therefore the separating measure of high-efficiency and economic must be taken, using correct separation equipment, meeting with the quality for ensuring oil product will
Ask.
Influence the practical factor of liquid-liquid two-phase laminated flow a lot, such as the characteristic and physical property, the reality of fluid of coacervation material itself
Border operation operating mode etc., liquid-liquid two-phase laminated flow is effectively realized in order to more economical, needs carefully to analyze in actual applications and grind
Study carefully the key factor of final influence liquid-liquid two-phase laminated flow, also study centrifugal separation processes Optimization control technology etc..Reinforcing point
Include improving rotary drum rotating speed from performance；Increase new motive force in centrifugal separation processes；Accelerate separating rate；Increase rotary drum is long
Degree makes time lengthening of centrifugal sedimentation separation etc..
Liquid-liquid two-phase laminated flow process generally comprises such two stages：
It is also the most important of which stage primary stage that agglomeration phase is.Dispersed phase droplet is under fluid forces along fiber side
To mutual shock, polymerization, so that aggegation becomes big, if drop is in the no aggegation well of agglomeration phase, then be difficult to dependence
Self gravitation settles down.
The different droplet collision of granular size is simultaneously coalesced together, and is then moved, collides, is condensed, until drop become greater to
Settled down by self gravitation.It is this first to soak the selected coacervation material reply drop tool of the coherent function method requirement collided afterwards
There is very strong trapping ability, it is related to the success or failure of whole agglomeration separation.
Second is separation phase, and the alternate interfacial tension of liquid-liquid two is bigger, and dispersed phase is easier to form big drop,
Two-phase also more can be easily separated.Fibre diameter and coalescence material average pore size in reduction equipment, to increase to dispersed phase droplet
Trapping ability, so as to improve flocculating result.
In the droplet settling stage, according to Stokes laws, very little is caused dispersed phase to sink by the sinking speed of drop
The drop buoyance lift time is elongated.Can reach and most economical efficiently separate mesh using heating fluid and by the way of cycling through separation equipment
's.
Two-phase density contrast is the premise for realizing liquid-liquid two-phase laminated flow, and the density contrast of two-phase is bigger, and sinking speed is faster,
Residence time is shorter, and the flow for the treatment of is bigger, so that the volume of equipment is just smaller.Except above-mentioned several influence coarse separation effects
Outside the factor of fruit, also just like：Structure type, practical operation condition of equipment etc..
Can be used for realizing that the equipment of liquid-liquid two-phase laminated flow mainly has at present：Single-stage coalescer, two-stage coalescing separator with
And three-stage filtration-coalescing separator, in addition with such as：Cyclone separator, inclined plate sedimentation separator and disk centrifuge etc..

Fluid can be liquid-liquid diffusion system pure, or containing trace solid impurity.Wherein have：Filer element type single-stage is coalesced
Device and material filling type single-stage coalescer.
Two-stage aggegation separator refers to filer element type two-stage coalescing separator, it is adaptable to which continuous phase is organic hydrocarbon, and dispersed phase is
Aqueous fluid, can contain a small amount of solid particle polluter in fluid.Two-stage coalescing separator inside is equipped with two kinds of difference in functionalitys
Filter core：One-level Coalescence filter core and the second-order separation filter core.
Filer element type two-stage coalescing separator is that current range of application is most wide, and a kind of liquid-liquid two-phase of service efficiency highest is coagulated
Collection separator device.Fluid dispersion phase content after its treatment can reach<10ppm, even up to arrives<5ppm .Due to filer element type
Condense separator to have a wide range of application, the Coalescence filter core specification that it is used in the world at present substantially carries out standardization.Fluid by
From inside to outside by Coalescence filter core, disperse phase liquid is so on the one hand conducive to drop in the accumulation of Coalescence filter core surface, sedimentation, on the other hand
Treatment flow can be improved, most economical two-phase laminated flow is realized.
Three-stage filtration condenses separator and contains a certain amount of solid impurity suitable for fluid.Fluid passes through single filter filter core
Solid grain contamination is dammed outside filter core, the fluid without solid particle enters back into two grades of Coalescence filter cores, from inside to outside
By Coalescence filter core, last separated filter core realizes thorough two-phase laminated flow.
It is to have added one-level pre-filtering on the basis of two-stage coarse separation that actually three-level condenses separation, due to solid in fluid
The presence of particle, it is necessary to first filter solid particle polluter, which adds two-phase laminated flow difficulty, simultaneously as coalescence is situated between
The aperture of matter is small, easily retains solid particle, causes Coalescence filter core lifetime, increases processing cost.But in order to realize liquid-
Liquid-solid three phase separation, improves aggegation efficiency and saves separation costs, and improving the cleanliness factor of fluid can select to use this kind of point
From equipment.
Foregoing several coalescing separators are entirely the standing type separation equipment under gravity separate, except this it
Outward, it is exactly disk centrifuge for separating the most representational rotation Dynamic Separation machinery of liquid-liquid two-phase.
