Description
Technical field
The invention belongs to water-oil separating material and lube purification field, its technology contents is related to a kind of method of fluid, especially
It is that WO emulsion is demulsified and is dehydrated by ultrasonic assistant high-effect water-oil separating nano material, can overcomes
The problem that existing breaking emulsion and dewatering technical method is present.
Background technology
Water-oil separating is always an important content in lube purification field, in the past use sedimentation, absorption, centrifugation, very
Space division can well be separated from oily water separation techniques such as, cyclonic separations to non-milky water present in fluid, be fluid
Technological means and method that field of purification is generally used.However, in many cases, the water in fluid does not exist in a free form,
But stable w/o type emulsion drop is formed in the presence of the interface active agents such as asphalitine, colloid, organic acid soap, due to
The presence of water droplet ambient interfaces film, the interfacial migration behavior of water is seriously obstructed, and causes traditional water-oil separating means to be difficult to make oil
Water separation process is smoothed out.Therefore, for a long time, breaking emulsion and dewatering is always emphasis and the difficulty that water-oil separating field needs to solve
One of point problem.
Existing research thinks that the destruction of emulsion need to experience the processes such as layering, flocculation, film draining, coalescence, therefore general
Physics breaking method is extremely difficult to required demulsification.By contrast, chemical demulsifier energy quick adsorption or aliquot replacement group
Into the natural interface active agent of oil-water interfacial film, the hybrid films lower than original interfacial film strength are formed, cause interfacial film to break
It is bad, release film in cladding water, complete demulsification process, therefore be still current demulsification preferably and apply most demulsification sides
Method.However, it is currently known the fact be that chemical demulsifier is difficult to reclaim and recycle in use, generally with sewage
To environmental emission, this not only causes demulsification cost to remain high, and also brings serious problem of environmental pollution.Emerging microorganism is broken
Although newborn technology has, environmental pollution is small, the advantage such as processing cost is cheap, because microorganism is strict to growth environmental requirement, easily
Influenceed by various environmental factors, therefore treatment effect is often very unstable, and popularization and application are also difficult at present.
In addition, for emulsus fluid dehydration problem, currently known technical method is to adopt demulsification process and dehydration
Carried out respectively with different technical methods, this also causes the unit increase of industrialization breaking emulsion and dewatering process, treatment in various degree
The problems such as efficiency is low, production cost is high.The appearance of high-efficiency water-oil separating nano material allows to carry out single treatment and comes real
Existing emulsus fluid breaking emulsion and dewatering is possibly realized, and by rational technological means, can not only enable emulsus fluid dewatered clean, also
It is avoided that a large amount of of chemical demulsifier use, reduces disposal of pollutants, while reduces processing procedure technique unit and processing cost.So
And up to the present, practical application of the high-effect water-oil separating material in breaking emulsion and dewatering field is still little.In order that high-effect
Water-oil separating material can be applied to the breaking emulsion and dewatering of emulsus fluid, the invention provides a kind of brand-new solution, solely
Breaking emulsion and dewatering is carried out by the high-effect water-oil separating material of ultrasonic assistant invasively, makes the breaking emulsion and dewatering of emulsus fluid by single
One processing procedure can be completed, and greatly improve the breaking emulsion and dewatering efficiency of emulsus fluid, in the hope of solving traditional oil-water separation method
The demulsification of insurmountable emulsus fluid difficulty, complex disposal process, treatment effeciency is low, processing cost is high, demulsifier bad adaptability
And exhaust emission it is big the problems such as.
The content of the invention
In order to overcome the shortcomings of the existing breaking emulsion and dewatering technology of water-oil separating field there are problems that and, the invention provides one kind
Brand-new solution, originally carries out breaking emulsion and dewatering by the high-effect water-oil separating material of ultrasonic assistant.The method has
Have processing procedure it is single, operation efficiently, strong adaptability, small secondary pollution the features such as, be very suitable for as water-in-oil emulsion
Liquid breaking emulsion and dewatering solution, the technical solution is once implemented, it would be possible to solve what conventional breaking emulsion and dewatering technology was present
Problem, produces good economic and social benefit.
The technical solution adopted for the present invention to solve the technical problems is：（1）Water-in-oil type emulsion breaking emulsion and dewatering system
It is made up of emulsion spray device, super oleophylic/super-hydrophobic sponge emulsion breaker, supersonic generator and sponge pressurizing unit, oil bag
Water-based emulsion is disposably by after device, you can realize breaking emulsion and dewatering.（2）Mist is carried out to emulsion feed using sprayer
Change, oil emulsion liquid mist can be turned to fine drop, and disperse in space, the resistance of medium being subject to when this causes that ultrasonic wave conducts
Smaller, wave field strength decay is less, and the effect acted on drop is stronger.（3）Auxiliary demulsification is carried out using ultrasonic wave, can be played
Ultrasonic activation is acted on and heat effect, promotes the surface reactive material in emulsion to be uniformly dispersed, and increases its solubility, reduces oil
The mechanical strength and viscosity of hydrosphere facial mask, so as to be conducive to the rupture of interfacial film.（4）Because super oleophylic/super-hydrophobic sponge is to oil
There is very strong affinity, there is very strong repulsive force to water, therefore when the dispersed phase drop in water-in-oil emulsion touches material
During surface, the interface oil film of emulsion droplet can be sprawled and infiltrated in material surface quickly, and therefore oil film ruptures, and is wrapped in it
In water can discharge, and repelled by the superhydrophobic characteristic of material, profit is separated.（5）Pressurizing unit is set, to oil suction sea
Silk floss is extruded, so that oil suction sponge de-oiling, the process performance of restorer, and speed up processing, extruding can also be certain
Promotion dispersed phase drop interfacial film breaking effect is played in degree.
The technical characteristics that the present invention has are：（1）Compared with existing breaking emulsion and dewatering technology, breaking emulsion and dewatering system is
One is overall, and demulsification and dehydration can be completed disposably in a short time, and processing unit is few, equipment investment and processing cost compared with
Conventional processing method is lower.（2）Emulsion feed is atomized using sprayer, oil emulsion liquid mist can be turned to tiny liquid
Drop, and disperse in space, suffered resistance of medium is smaller when this causes that ultrasonic wave conducts, and functioning efficiency is higher.（3）Using ultrasound
Ripple carries out auxiliary demulsification, can play ultrasonic activation effect and heat effect, is conducive to the rupture of interfacial film, improves demulsification effect
Rate.（4）Material is made full use of to the particular interface characteristic of oil and water to reach the purpose of fast emulsion breaking and dehydration, breaking emulsion and dewatering speed
Degree is faster, in hgher efficiency.（5）The breaking emulsion and dewatering technology that the present invention is provided does not use the generation environments such as demulsifier, adsorbent to pollute
With the raw material for increasing processing cost, whole processing procedure clean environment firendly, and strong adaptability can be used in processing various water-in-oil types
Emulsion.
