Description
Technical field
The invention belongs to water-oil separating material and lube purification field, its technology contents relates to a kind of method of fluid, particularly by ultrasonic assistant high-effect water-oil separating nano material, breakdown of emulsion and dehydration are carried out to WO emulsion, existing breaking emulsion and dewatering technical method Problems existing can be overcome.
Background technology
Water-oil separating is an important content in lube purification field always, the sedimentation in the past adopted, absorption, centrifugal, the oily water separation technique such as vacuum separation, cyclonic separation well can be separated the non-emulsified water existed in fluid, are the technological means that generally adopts of lube purification field and method.But, in a lot of situation, water in fluid does not exist in a free form, but stable w/o type emulsion drop is formed under the effect of the interface active agents such as asphalitine, colloid, organic acid soap, due to the existence 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 oil water separation process is carried out smoothly.Therefore, for a long time, breaking emulsion and dewatering is that water-oil separating field needs one of Focal point and difficult point problem solved always.
Existing research is thought, the destruction of emulsion need experience layering, flocculation, film draining, the process such as coalescent, and therefore general physics breaking method is difficult to reach required demulsification.By contrast, the natural interface active agent of chemical demulsifier energy quick adsorption or aliquot replacement composition oil-water interfacial film, form the hybrid films lower than original interfacial film strength, cause break down of boundary film, water coated in release film, complete breakdown of emulsion process, be therefore still the breaking method that current demulsification is preferably maximum with application.But the current known fact is, chemical demulsifier be in use difficult to reclaim and recycle, usually with sewage to environmental emission, this not only causes breakdown of emulsion cost to remain high, and also brings serious problem of environmental pollution.Although it is little that emerging microbial de-emulsification technology has environmental pollution, the advantages such as processing cost is cheap, but require strict to growing environment due to microorganism, be subject to the impact of various environmental factor, therefore treatment effect is often very unstable, is also difficult at present apply.
In addition, for emulsus fluid dehydration problem, current known technical method adopts different technical methods to carry out respectively breakdown of emulsion process and dehydration, and this also causes industrialization breaking emulsion and dewatering process unit to increase in various degree, the problems such as treatment effeciency is low, production cost is high.The appearance of high-efficiency water-oil separating nano material makes to carry out single process becomes possibility to realize emulsus fluid breaking emulsion and dewatering, by rational technological means, emulsus fluid can not only be made to be able to dewatered clean, a large amount of uses of chemical demulsifier can also be avoided, decreasing pollution discharges, and reduces processing procedure technique unit and processing cost simultaneously.But up to the present, the practical application of high-effect water-oil separating material in breaking emulsion and dewatering field is still little.The breaking emulsion and dewatering of emulsus fluid can be applied to make high-effect water-oil separating material, the invention provides a kind of brand-new solution, breaking emulsion and dewatering is carried out originally by the high-effect water-oil separating material of ultrasonic assistant, the breaking emulsion and dewatering of emulsus fluid can be completed by single processing procedure, and significantly improve the breaking emulsion and dewatering efficiency of emulsus fluid, in the hope of solving traditional oils water separating method insurmountable emulsus fluid breakdown of emulsion difficulty, complex disposal process, treatment effeciency is low, processing cost is high, demulsifier bad adaptability and the problem such as exhaust emission is large.
Summary of the invention
In order to overcome deficiency and the problem of the existing breaking emulsion and dewatering technology existence in water-oil separating field, the invention provides a kind of brand-new solution, carrying out breaking emulsion and dewatering by the high-effect water-oil separating material of ultrasonic assistant originally.The method have processing procedure single, run the features such as efficient, strong adaptability, secondary pollution be little, be very suitable for as water-in-oil type emulsion breaking emulsion and dewatering solution, this technical solution is once implement, likely will solve breaking emulsion and dewatering technology Problems existing in the past, produce 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 is made up of emulsion spray device, super oleophylic/super-hydrophobic sponge emulsion breaker, supersonic generator and sponge pressurizing unit, water-in-oil type emulsion is disposable by after device, can realize breaking emulsion and dewatering.(2) adopting sprayer to be atomized emulsion feed, can be fine drop by emulsification oil atomization, and dispersion in space, and the resistance of medium be subject to when this makes ultrasonic wave conduct is less, and wave field strength decay is less, and the effect acted on drop is stronger.(3) ultrasonic wave is adopted to carry out auxiliary breakdown of emulsion, ultrasonic wave effect of vibration and heat effect can be played, impel the surface reactive material in emulsion to be uniformly dispersed, increase its solubility, reduce mechanical strength and the viscosity of oil-water interfacial film, thus be conducive to breaking of interfacial film.(4) because super oleophylic/super-hydrophobic sponge has very strong affinity to oil, very strong repulsive force is had to water, therefore when the dispersed phase drop in water-in-oil emulsion touches material surface, the interface oil film of emulsion droplet can be sprawled at material surface and infiltrates very soon, therefore oil film breaks, the water be wrapped in wherein can be discharged, and repel by the superhydrophobic characteristic of material, profit is separated.(5) arrange pressurizing unit, extrude oil suction sponge, to make the de-oiling of oil suction sponge, the handling property of restorer, and speed up processing, extruding can also be played to a certain extent and promote dispersed phase drop interfacial film breaking effect.
The technical characteristics that the present invention has is: (1) is compared with existing breaking emulsion and dewatering technology, breaking emulsion and dewatering system is an entirety, breakdown of emulsion and dehydration can disposablely at short notice complete, and processing unit is few, and equipment investment and processing cost processing method all is more in the past lower.(2) adopting sprayer to be atomized emulsion feed, can be fine drop by emulsification oil atomization, and dispersion in space, and when this makes ultrasonic wave conduct, suffered resistance of medium is less, and functioning efficiency is higher.(3) adopt ultrasonic wave to carry out auxiliary breakdown of emulsion, ultrasonic wave effect of vibration and heat effect can be played, be conducive to breaking of interfacial film, improve breakdown of emulsion efficiency.(4) make full use of material to oil and the particular interface characteristic of water to reach the object of fast emulsion breaking and dehydration, breaking emulsion and dewatering speed is faster, and efficiency is higher.(5) breaking emulsion and dewatering technology provided by the invention does not use demulsifier, adsorbent etc. to produce environmental pollution and increases the raw material of processing cost, and whole processing procedure clean environment firendly, and strong adaptability, can be used in processing various water-in-oil type emulsion.
