Description
Technical field
The invention belongs to technical field of chemical separation, particularly relate to organic liquid film generator that a kind of bubble is auxiliary.
Background technology
Solvent extraction is a kind of more traditional industrial separation extractive technique, the advantages such as it has selective height, good separating effect, be easy to operation and applicability is strong, are thus widely used in the fields such as oil, chemical industry, pharmacy, metallurgy, environmental protection, bioengineering and fabrication of new materials.Along with the development of modern industry, separation system becomes increasingly complex, concentration of component to be separated is more and more lower, character that is separate object is more and more close, environmental improvement standard is more and more stricter, and people it is also proposed higher requirement to isolation technics and separation equipment.
Air assisted solvent extraction technology is the effect utilizing bubble agitation or bubble surface to adsorb and carry secretly, is scattered in the continuous aqueous phase of large volume by the oil phase of carrying organic extractant.Bubble, in uphill process, treats the organic extractant extraction trapping that extraction target components can be adsorbed by bubble surface or carry secretly in aqueous phase.With regard to mode of operation, air assisted solvent extraction is different from traditional profit two-phase extraction and adopts mechanical agitation to be dispersed with the mass transfer pattern of machine oil phase.Because air assisted solvent extraction process introduces air bubbles dispersion phase, organic oil phase of small size can be dispersed in the continuous aqueous phase of large volume, extracts the three-phase system that aqueous phase form greatly can strengthen the separative efficiency and extracting power for the treatment of object in extraction aqueous phase by bubble-organic oil phase-wait.In addition, bubble surface can also reduce the solution loss of organic oil phase in extraction process and secondary pollution to greatest extent to the adsorbing and trapping effect of organic oil phase.
CN 1962017A discloses a kind of air assisted solvent extraction method and equipment, and extraction equipment main body comprises gas and helps and subtract mixed extraction section, and its top arranges organic solvent inlet, and its lower end arranges distribution device in gas-fluid and aqueous phase outlet; Qi Zhu strengthening extraction district, its top arranges aqueous phase import, arranges moving component and driving shaft in district, and the drive unit at equipment top is by driving shaft brought into motion component movement; Three-phase enlarging Disengagement zone, its inside arranges bubble enlarging passage, and upper end arranges secondary organic solvent import and gas vent, and sidewall arranges organic solvent inlet.Gas helps the upper end subtracting mixed extraction section to arrange organic solvent inlet, and organic solvent directly enters Qi Zhu strengthening extraction district.This equipment traps organic solvent, concentration and separation organic matter or ionic species by Moving Bubble, decrease organic solvent to lose owing to being soluble in the aqueous phase and secondary pollution to aqueous phase, in Qi Zhu strengthening extraction district, carry out gas help strengthening liquid-liquid extraction, improve the extraction efficiency of equipment.But this equipment Shortcomings in design: is that organic solvent import is arranged on gas and helps the upper end subtracting mixed extraction section, distribution device in gas-fluid is located at gas and helps and subtract lower end, mixed extraction section, gas phase bloats bubble in the liquid phase after distribution device in gas-fluid distributes again, gaseous phase outlet and organic solvent export separate, they meet in uphill process is random, bubble absorption and to carry the probability of organic solvent secretly less, majority of organic solvent passive movement air bubbles dispersion has become little oil droplet, extraction mass transfer completes primarily of little oil droplet, and then by the little oil droplet of bubble trap.When heavy phase aqueous solution liquid flow is larger, organic light mutually little oil droplet cannot rise smoothly, very easily causes extracting and emulsifying; Two is that organic solvent directly enters Qi Zhu strengthening extraction district, and do not design the voltage stabilizing of liquid stream and apparatus for redistributing, gas phase does not consider the problem of voltage stabilizing too.In actual mechanical process, because the gentle phase pressure of organic solvent flow stream pressure is unstable, the dispersed very difficult realization of organic solvent, gas helps effect of extracting bad.
CN 102512848A discloses one and compares greatly liquid-liquid diphase continuous extraction apparatus, devises a kind of organic light phase dispersal device structure combined by liquid film distributor and air pressure surge chamber.Organic light light phase inlet from being positioned at bottom to pump into the interlayer space of liquid film distributor through mozzle, organic light spreading out in liquid film distributor panel surface forms light-phase liquid film.Be attached thereto logical pressure buffer room in lower end and blast gas, gas is through wireway, gently bubble surface is adsorbed on mutually by organic, bubble carries organic light phase, through the micro channel of liquid film disperser, from the ejection of liquid film disperser riser upper end micropore, form the air bubble liquid-membrane carrying organic light phase, be dispersed in tower in aqueous phase, contact mass transfer abundant with aqueous phase.The maximum advantage of this device is organic light phase export and gaseous phase outlet to merge, gas phase and organic gently contact after spray from same passage, the air bubble liquid-membrane formation rate of carrying organic light phase obtains certain raising, solves bubble and organic random problem of gently meeting.Organicly gently distribute comparatively even by this carrier of bubble, become greatly with the contact area of aqueous phase, organic light phase utilization rate and extraction efficiency are also improved.But also there is certain defect in this patent: although gas phase makes air pressure obtain certain buffering through gas buffer room, liquid film distributor is entered again through gas diversion tube, but only by the self-control of surge chamber bottom tower body, the effect played is very micro-, particularly at continuous operation, pressure can not get buffering and dispersed, this is not of uniform size by what cause bubble to be formed, even cause the hole had to have bubble to produce, the bubble that do not have had produces; And organicly gently pump into mozzle by pump, liquid film disperser laminated disk forms organic liquid film, in continuous-flow, also there is fluctuation in organic light phase pressure, make liquid film dish on variable thickness, some liquid films are thicker, blowout be oil droplet, the too thin blowout had be pure bubble, define in extraction process bubble, organic oil droplet, carry organic light phase air bubble liquid-membrane three kinds of dispersities and the phenomenon of depositing.Obviously, air bubble liquid-membrane formation rate is higher, and extraction and fractionation effect is better, more can farthest reduce solution loss and secondary pollution.
Therefore, how by structural design, air pressure and oil pressure to be uniformly distributed, generation air bubble liquid-membrane can be stablized, become the difficult problem that gas helps extraction urgently to be resolved hurrily.
