Description
Technical field
It declines channel liquid-liquid centrifuge extracter the present invention relates to a kind of reverse stream pipe, belongs to liquid-liquid centrifuge extracter technology neck
Domain.
Background technique
Realize that considerable hair just has been obtained in eighties of last century the seventies and eighties for the technology of liquid-liquid extraction using centrifugal force
, there are many kinds of cylindrical centrifugal extracters, is widely used in nuclear fuel material extraction and separation industry in exhibition, as: continuous contact model
Waves centrifugal extractor, Delaware formula centrifugal extractor；Be classified contact Lu Weisidashi centrifugal extractor, tubular type high speed from
Heart extracter, LX formula centrifugal extractor, BXP formula Cylinder Centrifuge extracter etc., the appearance of this this centrifugal extractor greatly pushes
The modernization development process of abstraction technique.But the structure and function of these centrifugal extractors is carefully analyzed, more or less
It comes with some shortcomings, such as: liquid holdup is big, structure is complicated, difficult disassembly and difficult cleaning, these deficiencies affect these Centrifugical extractions
Popularization and use of the machine during bulk pharmaceutical chemicals chemical industry synthesis are exactly that liquid holdup is big, extract wherein influencing maximum shortcoming
Element Theory series deficiency and difficult cleaning problems.
It is well known that bulk pharmaceutical chemicals during chemical industry synthesis, almost be unable to do without liquid-liquid extraction separation, nearly twenty or thirty year
Come, with the popularization of GMP regulation, this two requirements of low-residual, easy cleaning refuse many efficient liquid-liquid separation equipment in original
Expect except medicine synthesis, makes these advanced equipment that can not synthesize industry in bulk pharmaceutical chemicals, effectively promoted the use of, meanwhile,
Limit the automatic updating transformation process of bulk pharmaceutical chemicals synthesis industry.We just add existing centrifugal extractor one by one below
To illustrate.[the following contents is most of quoted from " cylindrical centrifugal extracter " Ye Chunlin, Atomic Energy Press, in December, 2007]
Waves centrifugal extractor (continuously contacts with formula): the concentric circles with sieve pore is housed in the rotary drum of waves centrifugal extractor
Cylinder.Heavy phase is introduced from rotary drum center, and axle envelope of the light phase through center is introduced by the outer rim of rotary drum.Under the influence of centrifugal force, heavy phase
It is thrown to rotary drum edge by the sieve pore of concentric drums to draw through center axle envelope, light phase presses to center by heavy phase, in concentric circles shaft screen
Fierce counter current contacting mass transfer occurs for two-phase at hole.The advantages of equipment is that revolving speed is high, centrifugal force is big, treating capacity is big, liquid holdup
It is relatively small；Shortcoming is that manufacture is difficult in maintenance, investment cost is high.Further, since the mixing of weight two-phase only occurs in sieve
At hole, it is unable to reach highly effective mixing, so two-phase contact area is limited, single device theoretical stage is difficult to do height.Together
When, it since this equipment can not be made very small, can be only applied in large batch of production process, can not be perfectly suitable for small quantities of
Amount, the operating condition of multiple batches of and multiple extraction.Moreover, the greatest problem of the equipment is, disassembly is difficult, it is difficult to accomplish thoroughly to clean,
It can not meet the requirement of GMP regulation.
Delaware formula centrifugal extractor (continuously contacting with formula): it is provided in the rotary drum of Delaware formula centrifugal extractor many same
Heart cylinder.The concentric drums outer surface has helical form floor, and one end of each cylinder is provided with flow ports, the other end and rotary drum
Shell sealing.When concentric drums are put into rotary drum, liquid flow ports will be staggered.Light phase from rotary drum outer rim introduce, heavy phase from
Rotary drum center introduces, two-phase liquid reverse movement in helical flow path, and heavy phase is flowed outward by the flow ports of cylinder, and light phase is logical
Cylinder flow ports are crossed to flow to the center of circle.Two-phase iterates through flow ports, carries out repeatedly adverse current mixing and improves extraction efficiency.This sets
Standby advantage is by the way of counter-current extraction, and extraction efficiency increases, and treating capacity is big, but due to liquid flow path ruler
It is very little excessive, inside do not have filler, leading to weight two-phase not can be carried out highly effective mixing, mass-transfer efficiency be not it is very ideal,
So single machine is extremely difficult to higher extraction series.Simultaneously as this equipment can not be made very small, high-volume can be only applied to
Production process in, the operating condition of small lot, multiple batches of and multiple extraction can not be perfectly suitable for.In addition, the maximum of the equipment
Problem is that disassembly is difficult, it is difficult to accomplish thoroughly to clean, can not meet the requirement of GMP regulation.
Lu Weisidashi centrifugal extractor (classification contact): there are three being set in the rotary drum of Lu Weisidashi centrifugal extractor
Mixing clarification grade.Mixed zone is close to central axis, and settling section is in its periphery.The pump impeller of mixed zone has mixing and suction two-phase liquid real
The effect of existing mass transfer and countercurrent movement.The equipment advantage is that treating capacity is big, and there are three theoretical stages, but since its structure is complicated, system
It makes higher with maintenance cost.Simultaneously as this equipment liquid holdup is bigger than normal, only there are three theoretical stages, can be only applied to large quantities of
In the production process of amount, the operating condition of small lot, multiple batches of and multiple extraction can not be perfectly suitable for.And the equipment is equally
It is difficult in the presence of disassembly, it is difficult to accomplish the problem of thoroughly cleaning, can not meet the requirement of GMP regulation.
Tubular type High-speed centrifugal extraction machine (classification contact): tubular type High-speed centrifugal extraction machine can arrange this as representative using Sharp,
It is set in pipe there are three mixing clarification grade, it can be rotated under the high speed of 20000r/min, and the centrifugal force of generation is up to the one of gravity
Wan Bei, therefore separating effect is fine, is commonly used to separate the little material of relatively valuable treating capacity.The advantages of equipment is separation effect
Fruit is good, but since its revolving speed is very high, very stringent to requirement for dynamic balance, and requirement on machining accuracy is high, so manufacture is relatively difficult.Together
When, since only there are three theoretical stages for it, so being also not suitable for extraction series requires more extracting operation, popularization is also limited
System.
LX formula centrifugal extractor (classification contact): LX formula centrifugal extractor has 8 mixing clarification grade assembly in rotary drum
On a vertical pivot, every grade is mixed (liquid in rotation) with the disk maintained static, and settling section is in mixed zone periphery.LX formula from
The characteristics of heart extracter is multiple mixing clarification grades that can connect on a vertical pivot, and the device structure is compact, and extraction series is high, but
Drum structure is complicated, and manufacturing cost is high, and disassembly is difficult, it is difficult to accomplish thoroughly to clean, can not meet the requirement of GMP regulation.
BXP formula cylindrical centrifugal extracter: BXP formula cylindrical centrifugal extracter rotary drum be it is upper outstanding, on a vertical pivot
Equipped with rotary drum and blender, so as to carrying out mixing clarifying process, the advantages of equipment is that structure is simple, and processing and manufacturing is easy, and is taken
It is easy to maintain with low.The machine only drawback is that, since its structure is too simple, so single machine can be only done a theoretical stage
Extracting operation, more operating condition is required for theoretical stage, single device is unable to satisfy requirement, it is necessary to use multiple devices string
Connection could complete operation, and space occupied is relatively large.
By above-mentioned analysis, existing Centrifugical extraction is confidential to be applied well in bulk pharmaceutical chemicals chemical industry synthesis separation process,
It is subject to certain restrictions.Up to the present, more by bulk pharmaceutical chemicals batch, the small, low-residual of batch and equipment cleaning require high production
The restriction of feature still can not find a liquid-liquid centrifuge that can be perfectly suitable for bulk pharmaceutical chemicals chemical industry synthesis separation process
Extracter needs constantly exploratory development, is corrected improvement to these liquid-liquid centrifuge extracters, produces and be more suitable for original
Expect the liquid-liquid centrifuge extracter of medicine chemical industry synthesis separation process.
