Rotary extraction tower in industrial production application restrictions
a, when the extraction equilibrium series (rarely Less than 2) More economic, use mixer settler. The extraction equilibrium series a lot ( More than 10) System, also is not appropriate.
2, the interfacial tension is very low or very small difference in density between system, emulsion or rotary stirring extraction tower can lead to system greatly reduce the production ability, this type of system is rotary extraction tower in industrial production application restrictions.
3, the liquid in the turntable extraction tower stay longer. For the unstable system, under the extraction temperature degradation will happen. At this time should choose short residence time of equipment, such as centrifugal extractor.
4, for driving and parking factory frequently, because each time to re-establish rotary fluid extraction tower - Fluid balance, trouble arduous, it is better to choose other extraction device (step by step Such as mixer settler or centrifugal extractor) 。
in short rotary extraction tower in industrial production application restrictions are a fraction of its capabilities, in the industrial production wheel still has its do not replace the position of extraction tower.
