extraction ( Especially liquid - Liquid extraction) Refers to a kind of do not miscibility with water, can dissolve and extract a large number of organic solvents, Extracting agent) With the extract of aqueous solution ( Raw material liquid) Mix, after fully mixing, be extract into organic solvent, and because the relative density is different, after clarification and divided into two layers, a layer of water phase ( More than extraction phase) And the other a layer of organic phase ( Extraction phase) ( In general, organic phase in the upper, aqueous phase in the lower layer) 。 So as to achieve the purpose of the separation, purification, or enrichment.
extraction process includes two sections, namely extraction and reverse extraction. In extraction, water phase and organic phase in extraction equipment to fully mix, stay in the material liquid extraction of solute transfer as much as possible to the organic phase, and then clarify, extraction and extraction separation. After the extraction separation and extraction residue extraction and solvent recovery processing respectively. During the extraction, extraction within the selected extraction agent were mixed, solute by extraction and extraction separation and into the extraction liquid, after the extraction of organic phase regeneration, the back extraction period of recycling.
extraction is actually a mass transfer process, including the following three steps:
scatter one phase to another phase, forming a large interfacial area;
in the dispersed phase and continuous phase contact time, the mass transfer process of balance;
the dispersed phase droplet aggregation, with the continuous phase separation.
in extraction equipment, two liquid repeated 'scattered - Mass transfer - Polymerization process. ' Widely used in the extraction equipment mainly extraction tank, extractive tower and centrifugal machine.










DE source extraction to recommend extraction principle introduction to help you understand the extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
