Now sending out filtrate pure with triphase one-step extraction process to purify penicillin is example, briefly introduces the design feature and the operating conditions of device provided by the invention:
In triphase one-step extraction process to purify penicillin ferment filtrate process, heavy phase is a penicillin fermentation filtrate, and the centre is the polyethylene glycol aqueous solution mutually, gently is butyl acetate mutually.Except opening steam vent 81 and heavy phase import 10, other each import and export are all closed in advance on the horizontal reactor 1 inject liquid in horizontal reactor 1 before.Penicillin fermentation filtrate (heavy phase) enters horizontal reactor 1 from heavy phase import 10 earlier, arrives liquid level 22 up to it, opens heavy out 15, makes heavy phase keep flow regime; Then, phase import 16 allows the polyethylene glycol aqueous solution (middle phase) enter horizontal reactor 1 thus in the middle of opening, and after it arrives liquid level 21, exports 7 mutually in the middle of opening, and keeps flow regime in the middle of making mutually; And make middle phase liquid and heavy phase liquid be counter current contacting; At last, butyl acetate (light phase) phase import 4 on the lenient side flows into horizontal reactors 1, up to its with horizontal reactor 1 in remaining air drain, be full of whole horizontal reactor 1.At this time close steam vent 81 and open light phase export 18, make the continuous-flow of light phase liquid.So far, each phase liquid all carries out continuous-flow by horizontal reactor 1.In running, can regulate by separator-pump (heavy out control), control interface 22 (being heavy phase and middle interface between mutually), by pump-separator (light phase export control) adjusting, control interface 21 (promptly light and centre mutually between interface).
The axle (promptly going up axle 5 and lower shaft 9) of two levels is arranged in this device, drive respectively, slowly rotate by two motors.In three phase mixtures (H), vertical separately upper guard-plate 2 and the under shield 13 of being equipped with on last axle 5 and the lower shaft 9, a plurality of circular-arc lifting buckets 3 are housed between every adjacent screen, and opening is towards direction of rotation, and upper guard-plate 2 and under shield 13 form the annular gap with the equipment outer wall.
In three phase mixtures (H), when lower shaft 9 drives under shield 13 above it and rotates, interface 22 upper areas, phase (PEG) liquid in the middle of the circular-arc lifting bucket 3 that one end has drenched heavy phase has been ladled out, the other end circular-arc promotes the heavy phase (H that bucket 3 has been ladled out during the rotation of 22 lower areas at the interface simultaneously 2O) liquid drenches into middle phase (PEG) with the form of drop (decentralized photo).22 lower areas at the interface, the circular-arc lifting bucket 3 of disk one end has been ladled out heavy phase (H 2O), after the circular-arc lifting bucket 3 middle phases (PEG) of having been ladled out when interface 22 upper areas rotate of the other end enter heavy phase as decentralized photo simultaneously, and upwards elegant with the drop form, two-phase is mixed in this way, mass transfer.
In like manner, in three phase mixtures (H), when last upper guard-plate 2 that drives above it rotates, 21 upper areas at the interface, circular-arc liftings of phase bucket 3 had been ladled out light phase (BA) liquid in the middle of one end had drenched, and the other end circular-arc promotes barrels 3 middle phase (PEG) liquid of having been ladled out during the rotation of 21 lower areas at the interface and drench into light phase with the form of drop (decentralized photo) simultaneously.21 lower areas at the interface, phase (PEG) in the middle of the circular-arc lifting bucket 3 of upper guard-plate 2 one ends has been ladled out, simultaneously circular-arc liftings bucket 3 light phase (BA) liquid of when interface 21 upper areas rotate, having been ladled out of the other end enter as decentralized photo the centre mutually after, and upwards elegant with the drop form, two-phase is mixed in this way, mass transfer.
Subsequently, heavy phase (H 2O) enter clarification phase-separating section Q1 with the light porous division board 14 of (BA) liquid through filling filler mutually, and after this clarification, phase-splitting device for transferring; The porous division board 14 of middle phase (PEG) liquid through filling filler enters clarification phase-separating section Q2, and after this clarification, phase-splitting device for transferring.
By said process the extraction of liquid-liquid-liquid three-phase original position is carried out continuously, impurity such as foreign protein, mycelia, pigment are extracted into the water-soluble liquid phase of polyethylene glycol (middle phase) together and export 7 mutually from the centre and discharge; Penicillin fermentation filtrate (heavy phase) after the raffinate is discharged from the heavy out 15 that is positioned at device bottom; Penicillin is then come together to go in the butyl acetate continuously, and the light phase export 18 through being positioned at the equipment top is discharged, thereby has finished whole liquid-liquid-liquid three phase continuous extraction process.In actual production process, material into and out of all being continuously to carry out.
The horizontal reactor of this equipment, baffle plate, circular arc promote parts such as bucket, porous division board, axle and all can adopt the metal material manufacturing.If use this equipment, then should adopt the stainless steel that meets the GMP standard at pharmaceutical industry.Device bottom should be provided with support, and each liquid phase import and export place reserves flange-interface, drives so that fix, pacify installation and dismantling.
In sum, liquid-liquid-liquid three-phase continuous horizontal type lifting stirring extractor involved in the present invention has been realized the extraction of liquid-liquid-liquid three-phase continuous in-situ first.Have reduce back-mixing, theoretical stage height, extraction efficiency height, simple in structure, easy amplification, continuously-running, energy consumption low, take up an area of advantages such as economizing, be easy to recover steady state operation, be applicable to contain the solid matter and the easy biogenetic products extraction separation process of emulsification.The present invention provides the reliable device support for triphase one-step extraction process to purify penicillin and other liquid-liquid-liquid three phase extraction technology in industrial large-scale application, greatly reduce the expense in the Related product purifies and separates process, can effectively solve puzzlement industry " bottleneck " problem for many years, be of great immediate significance.
