Supergravity extraction separation couple device and its application

Abstract

A supergravity extraction separation couple device and its application are provided. A supergravity mixing unit and an extraction separation unit are simultaneously arranged, the supergravity mixing unit first disperses at least one of that light phase fluid and the heavy phase fluid into micro-nano scale droplet, and mixes the two fluids to form an extraction mixed fluid, the contact area of thetwo-phase fluid is increased, on the other hand, the light phase fluid and the heavy phase fluid in the extraction mixture fluid are separated by centrifugation in the extraction separation unit, thedispersion of one phase and the mixing efficiency between the two phases are improved, and the extraction equilibrium time is shortened, and moreover the centrifugal force generated by a driving motorin the supergravity mixing unit can simultaneously act on the extraction separation unit, on the one hand, the separation time is shortened, on the other hand, the power consumption is saved, and theenergy utilization rate is improved.

Description

Technical field [0001] The invention relates to the technical field of extraction and separation, and more specifically, to a supergravity extraction separation coupling device and application. Background technique [0002] Liquid-liquid extraction, also known as solvent extraction, can generally be divided into two processes: two-phase mass transfer and two-phase separation. The principle is to use the difference in solubility of each component in the raw material liquid in an appropriate solvent to achieve the separation of the components in the mixed liquid. . [0003] Extraction separation has the advantages of normal temperature operation, low energy consumption, good selectivity, easy continuous operation and automatic control. It is widely used in chemical, petroleum, food, pharmaceutical and other fields. The extraction and separation process is mainly completed by a three-stage cycle of dispersion-mass transfer-coalescence. To achieve the extraction of the components to b...

Problems solved by technology

Among them, mixing clarifiers, packed towers, plate towers, etc. rely on gravity to realize the clarification between the two phases. When the density difference between the two liquids is small or the volume ratio is large, or the interfacial tension is small and easy to emulsify or the viscosity is high, it is difficult to achieve two phases by gravity. phase well mixed or clarified

Therefore, there are many deficiencies that are difficult to overcome in the current extraction equipment.
