Description
Technical field
The present invention relates to liquid-liquid two-phase solvent extraction equipment in a kind of medicine, metallurgy or biochemical field, be specifically related to a kind of low rotating speed self-priming extraction equipment, particularly in a kind of continuous extraction apparatus of large phase ratio easy emulsifying system.
Background technology
Solvent extraction is a kind of efficient separation and extraction technology, is 21 century one of the most promising green chemical industry developing direction.An important branch as chemical separating subject, abstraction technique can be selected suitable extraction system and flow process according to separate object and technological requirement, there is selective height, good separating effect, the feature such as easy operating and strong adaptability, thereby be widely used in the fields such as hydrometallurgy, petrochemical industry, atomic energy chemical industry, medicine, environmental protection, bioengineering and fabrication of new materials.But when extraction application is during in these fields, emulsion is distinct issues relatively in extraction process.
Because living things system is all very responsive to soda acid, organic solvent and mechanical shear stress etc., adopt the violent extraction mode of mixing of common paddle to be easy to cause inactivation and decomposition.In the separation and purification of biological product, emulsion is more outstanding.Such as: in antibiotic zymotic fluid, contain a large amount of protein and sugar etc., in organic solvent extraction process, protein molecule is easy to sex change.If adopt common agitating mode to mix, speed is too low can not complete extraction process, and the protein of a large amount of sex change can be adsorbed in high speed shear destruction generation a large amount of size of grains interface, form even protein cross structure of firm interfacial film, make emulsion become highly stable.The formation of emulsion is very unfavorable for extraction process, and emulsification causes the useless zymotic fluid of raffinate to carry solvent secretly, reduces product yield, meanwhile, carries zymotic fluid secretly and also to recycling, cause difficulty in organic phase.
Solvent extraction is the extracting penicillin history of existing more than 50 years from zymotic fluid, but extraction process does not have to change substantially: extraction equipment used adopts drum-type centrifugal extractor and decanter at present mostly, extractant used is mainly acetic acid fourth (penta) ester, methylisobutylketone etc.Extracting operation condition is: pH is 1.8～2.2, organic phase and water volume ratio O/A=1/2, and back extraction pH is 6.7～7.2, compares O/A=2/1.In extraction process, there are following two features: (1) penicillin destructible, relatively stable in pH 4～8 scopes, at pH < 4 or pH > 8, all easily decompose.At 2.0,10 ℃ of pH, the half-life of penicillin is 1.3 hours, and extraction will complete within very short time.In addition, what in two-phase, mix use is that oar formula stirs, and required rotating speed is higher, and this is destroyed the biologically active of penicillin.(2) owing to containing a large amount of protein, organic pigment and other biological byproduct in zymotic fluid, so emulsification is serious in extraction process.
CN 1047293A discloses a kind of composition and extracting process of extracting penicillin, described extracting process adds neutral phosphor (phosphine) class or sulfoxide compound in butyl acetate, make itself and butyl acetate form mixed extractant solvent penicillin, can make operating condition bring up to 3.0～3.5 from pH 1.8～2.2, yield has improved 3%.But this technique does not change on extraction equipment, and the effect that causes the method to obtain is in actual applications not fairly obvious.
At present, for solving the emulsification problem of mixed solvent, the efficient centrifugal extractor of industrial employing carries out Centrifugical extraction.But the defect of centrifugal extraction method is that equipment investment is larger, adopts centrifugal extraction method to be also difficult to emulsification to eliminate, and in technical process, must use demulsifier.Take North China Pharmaceutical Factory as example, and in annual penicillin production technique, the demulsifier consumption needing just reaches more than 1,000,000 yuan.
< < Liquid-liquid Extraction Processes and equipment > > (Atomic Energy Press, 1993, Fei Weiyang etc.) book is pointed out: when carrying out the selection of extraction equipment, the extraction of difficult clarification system is generally used centrifugal extractor and barrel formula extractor of drenching with rain.Centrifugal extractor is to carry out two-phase fully to mix fast, and utilize centrifugal force to replace the extraction equipment of the quick phase-splitting of gravity, though can solve the problem of phase-splitting difficulty, but shortcoming is complex structure, manufacture, operation and maintenance costs is higher, due to rapid stirring, shearing force causes more serious emulsion compared with great Yi in addition.Rain type extractor is a kind of horizontal successive extractor, the material that is applicable to process conventionally easily emulsification and contains solid particle, but that shortcoming is rotating speed is slow, mass transfer rate is low, lower than loading.
