For extraction equipment selection, you could refer to the flowing principle:
1. Stability and residence time;
2. Clarification characteristics of solvent system;
3. Equipment cost and maintenance;
4. Theoretical stage requirements;
5. The area covered by the equipment and building height;
6. Handling capacity;
7. The system physical property.
The comment extraction equipments are mixer settler, extraction column, centrifugal extractor. And we have made feasibility report to these equipments, found that centrifugal extractor is the ideal in effect, adaptation, volume efficiency, space occupied, emulsifying ability.
Especially CWL-M series of centrifugal extractor, it is a new type of liquid-liquid extraction and separation equipment, with our own independent intellectual property rights and patents. it has essential difference in principle with traditional extraction equipments such as mixer settler, extraction column and so on.
Centrifugal extractor adopt motor to drive the bowl with high-speed rotation, under the condition of shear force generated by bowl or blade rotation, two different density and immiscible liquids complete mixing and mass transfer; and separated rapidly by centrifugal force generated by high-speed rotation of
Advantages Of CWL-M series of Centrifugal Extractor
Our CWL-M series of centrifugal extractor is our independent R&D equipment with patents, it is different with other traditional extraction equipments, with many advantages, For example:
1. Simple and stable structure
Top-suspension structure, no bearing and mechanical seal at the bottom, no leakage risk, easy to maintain and save maintenance cost, long service life;
Large capacity, more energy-saving (under the same capacity condition, the power consumption is 1/10-1/3 of the annular type);
3. Corrosion resistance
Equipment could adopt perfluoro polymer material, resistant to strong acid (hydrochloric acid, mixed acid etc.);
4. Good effect of mixing and separation
Various hybrid structures could be chosen, good separation effect, adapt to easily emulsified system;
5. Easy to change heavy phase weir
When changed liquid system, heavy phase weir could be replaced quickly, simple and easy operation;
6. Low liquid residual
Equipment with small valid volume;
7. High automation
It could realize timely monitoring on line, optional on-line cleaning system for GMP standard, and adapt to both intermittent and continuous running completely.
