Description
Technical field
The present invention relates to a kind of liquid-liquid-liquid three phase continuous extraction device, particularly, the present invention relates to the adjustable three phase extraction groove of a kind of parameter.
Background technology
In separation science, the liquid-liquid extraction technology is a kind of important isolation technics, is to make solute be transferred to the another one liquid phase from a liquid phase through the mode of adding cenotype.Extraction process is widely used in the processing and the fields such as post processing, food industry, biochemical industry and environmental project of chemical industry, petroleum refining industry, mineral comprehensive utilization, nuclear fuel.Along with development of modern industry, people have proposed more and more higher requirement to isolation technics, and the comprehensive utilization of the preparation of high purity material and the deep processing of various product, resource, the execution of environmental improvement strict standard have promoted the development of separation science and technology greatly.
Development along with abstraction technique; Some new abstraction techniques are come out one after another, like complexation extraction, Membrane Extraction, supercritical liquid extraction technique, aqueous two-phase extraction, micelle reverse micelle extraction process, outfield strengthening extraction technology and other novel extraction technology etc.The appearance of these novel extraction technology for the enforcement of extraction process provides wide research space, is also had higher requirement to the exploitation of extraction equipment simultaneously.
The liquid-liquid-liquid three phase extraction technology of Chu Xianing is a kind of special extraction system in recent years, and it comprises the extract and separate system of three balance liquid phases, and it is a kind of new method to the complex system separation and purification.Adopt the liquid-liquid-liquid three phase extraction can realize a separation system is separated simultaneously a plurality of components or divides into groups, the raising separative efficiency is particularly useful for the multi-component complex system.The liquid-liquid-liquid three-phase system mainly comprises following three types:
I class: the three-phase system of forming by the third phase that generates in organic facies/water extraction system and the extraction process thereof;
II class: the three-phase system that constitutes by two immiscible organic facies and a water;
III class: the three-phase system of forming by two immiscible waters and an organic facies;
Wherein the I class three-phase system set up is spontaneous formation in the extraction process, and is uncontrollable, and needs high acidity environment become phase condition harshness to be difficult to industrial applications; As when using the organic phosphine compound that is dissolved in the saturated hydrocarbon to extract strong mineral acid or metal ion, tend to cause the appearance of third phase.II class and III class extraction system can be carried out arteface, and controlled and good stability need not under high acidity, to carry out.This diplobiont system has been applied to fields such as biomolecule extraction, the extraction of natural products useful constituent, multicomponent wastewater treatment, many metals leaching system in the biofermentation system at present; Tentatively demonstrate excellent separating property; For the three phase extraction technology is pushed to commercial Application, need the three phase extraction equipment of development of new.
The operator schemes that adopt organic addition one water of two-phase extraction in the past adopt two phase countercurrent flow or cocurrent cooling operation more, and the extraction equipment of this generic operation has comprised stirring extraction tank, mixer-settler, liquid-liquid extraction post, centrifugal extractor etc.Along with the development of three phase extraction technology, three phase extraction equipment such as liquid liquid liquid three phase continuous extraction vibrating sieve plate tower (CN02106742.2), liquid-liquid-liquid triphase horizontal continuous lifting stirring extraction device (CN02121210.4), a kind of serial self-suction type multi-channel phase dispersing extractor (CN00107700.7) etc. are developed in succession.Yet these extraction equipment structures are comparatively complicated, complex operation, and manufacture difficulty is bigger.For this reason, propose a kind of new three phase extraction method, the three phase extraction process is reduced to the two-phase extraction process.The two-phase flow is merged into one carry out countercurrent mass transfer, so just can carry out innovation transformation, realize the three phase extraction process original many two-phase extraction devices with third phase.
According to the mixer-settler that is used for three phase extraction (CN200910090899.X) of the mentality of designing of three-phase and the two-phase design part that comes with some shortcomings, as last as a phase, in after mixing, carry out mass transfer mutually on next with adverse current down as one.Can not solve middle as a phase time and the following countercurrent mass transfer that carries out mutually.Can't be applicable to the three phase extraction system that constitutes by two organic facies and a water.Need develop for this reason the operator scheme of phase-following phase countercurrent mass transfer in can either being applicable to can be applicable to again phase-in the novel extraction equipment of operator scheme of time phase countercurrent mass transfer.We have developed the adjustable three phase extraction groove of new-type each parameter for this reason, can be applicable to that II class three-phase system extraction process can realize the extraction process of III class three-phase system again.
