Description
The present invention relates to the extraction equipment of solvent in medicine, the biological chemical field, particularly a kind of self-absorption multichannel phase dispersing extractor.
In metallurgy, oil, pharmacy, food industry, emulsion is to compare distinct issues in the extraction process.Because living things system is all very sensitive to soda acid, organic solvent and mechanical shear stress etc., adopt the violent extraction mode of mixing of common stirring arm to be easy to cause inactivation and decomposition.In the separation and purification of biological product, emulsion is more outstanding.Such as: contain a large amount of protein and sugar etc. in the antibiotic zymotic fluid, protein molecule is easy to sex change in the organic solvent extraction process.If adopt common alr mode to mix, speed is too low can not finish extraction process, and high speed shear is broken and is produced a large amount of emulsion granular boundaries and can adsorb the protein of a large amount of sex change, forms firm interfacial film even protein cross structure, makes emulsion become highly stable.The formation of emulsion is very unfavorable for extraction process.Emulsification causes the useless zymotic fluid of raffinate to carry solvent secretly, reduces product yield.Simultaneously, carry zymotic fluid in the organic facies secretly and also cause difficulty to recycling.
For example: solvent extraction extracting penicillin from zymotic fluid has the history in year surplus in the of 50, but its extraction process does not have to change substantially: used extraction equipment adopts drum-type centrifugal extractor and decanter at present mostly, used extractant mainly is acetate fourth (a penta) ester, methylisobutylketone etc.The extracting operation condition is: pH1.8-2.2, and organic facies and water volume ratio O/A=1/2, O/A=2/1 is compared in back extraction pH6.7～7.2.Following two characteristics are arranged in its extraction process: 1, penicillin is easily destroyed, and is more stable relatively in pH4～8 scopes, in pH＜4 or pH＞8 all easily decompose.At pH2.0, under 10 ℃, the half-life of penicillin is 1.3 hours, and extraction will be finished in very short time.2, contain a large amount of protein, organic pigment and other biological byproduct owing in the zymotic fluid, so emulsification is serious in the extraction process.
