Description
Technical field
The present invention relates to profit dispersion technology field, particularly in a kind of aqueous solution, produce the device and method of oil film bag air bubbles dispersion phase.
Background technology
Chemical field usually relates to reaction between two immiscible liquid phases and mass transport process.Two immiscible liquid phases will realize Homogeneous phase mixing, a certain phase need be made to be distributed in another phase equably, provide larger two-phase contact area thus.But, when a certain relatively another phase volume in two-phase is less, more difficult realize dispersed.The oil phase of small size is distributed in the aqueous phase of large volume, general employing be mechanical agitation dispersing mode (Fei Weiyang. Liquid-liquid Extraction Processes and equipment. Beijing: Atomic Energy Press, 1993), but the scope of comparing that the method is suitable for is also little (general water: comparing of oil is less than 30).For easy emulsifying system, the method is more inapplicable.
CN86107681A discloses the method and apparatus that a kind of water-oil phase disperses small size oil phase after cyclone mixer, but described cyclone mixer is static mixer, the dispersion of small size oil phase in bulk water phase is uneven, and device structure is complicated, manufacture and maintenance cost high, be unfavorable for popularization.CN1256168A discloses a kind of liquid injecting mixed device, a kind of liquid winding-up in immiscible two kinds of liquid is separated into small sized particles decentralized photo, be mixed with emulsion with the immiscible liquid of another kind (it is as continuous phase), reach with this object strengthening two-phase contact area.But the method needs applying surface activating agent with the granule liquid of stable dispersion, very easily causes emulsification, two-phase phase-splitting difficulty.CN102512848A discloses one and compares greatly liquid-liquid diphase continuous extraction apparatus.First this device adopts liquid film distributor that organic for small size oil phase extruding is formed the organic oil film of one deck thin layer, then utilizes liquid film disperser to blast bubble continuously, is distributed in the aqueous phase of large volume by organic for this thin layer oil phase by bubble.The prerequisite that this device realizes above-mentioned functions is that the organic oil phase of small size need be squeezed into the organic liquid film of thin layer in advance, but because oil-in is arranged on one end of grease chamber, oil pressure skewness in grease chamber, be difficult to obtain the organic liquid film of the homogeneous thin layer of thickness, actual mechanical process effectively cannot control the dispersity of organic oil phase.The mixing dispersity of what gas helped dispersion oil phase process often to obtain is tiny oil droplets and/or bubble surface oil film (being referred to as oil vacuole), is even also mixed with the bubble not being adsorbed with machine oil phase in a large number.
CN1524602A discloses a kind of bubbling sieve-plate tower extracting process and equipment thereof, first prepares the mixture of a kind of bubble and organic oil phase, and wherein bubble is decentralized photo, and oil phase is continuous phase.And then blast extraction tower through the oil phase that this to be mixed with a large amount of bubble by calandria liquid distributors.But the method and device cannot realize the organic oil phase of small size and enter tower body in the mode forming " oily bag gas " air bubble liquid-membrane, during the two phase countercurrent flow operation of water oil, very easily cause emulsification, be difficult to clarify phase-splitting.Li Zhen etc. (oil vacuole flotation technology is inquired into. Chinese Mining Industry, 2013,22(10): 117-130) kerosene heating is become kerosene steam, then kerosene heat steam is frothed and blast the aqueous solution, kerosene vapours is adsorbed on bubble surface after condensation in aqueous, forms the oil vacuole of oily bag gas in aqueous.But the method is achieved and depends on kerosene vapours condensing rate in aqueous, the oil film bag air bubbles dispersion phase surface oil film thickness of generation is uncontrollable, cannot obtain stable oil film bag air bubbles dispersion phase.
