Solvent Extraction Centrifuge

Description Of Centrifugal Extractor

The centrifugal extractor is a new, fast and efficient liquid-liquid extraction and separation equipment. It is fundamentally different in working principle from traditional extraction equipment such as mixing and clarifying tanks and extraction towers. The centrifugal extractor uses a motor to drive the drum to rotate at high speed. Two liquids with different densities and immiscible liquids are mixed and mass transferred under the action of the shear force generated by the rotation of the drum or blades, and the high-speed rotation of the drum produces Rapid separation under centrifugal force. Working principle Of Centrifugal Extractor


1. Mixed mass transfer process
The light and heavy phase solutions enter the mixing chamber from the light phase inlet and heavy phase inlet in a certain proportion, and the mixing and mass transfer process is quickly completed under the action of the stirring paddle.
2. Two-phase separation process
The mixed liquid enters the drum under the action of the static turbine. In the cavity area formed by the web, the mixed liquid quickly rotates synchronously with the drum. Under the action of centrifugal force, the heavy phase liquid with high density gradually moves away during the upward flow process. The center of the drum moves toward the drum wall; the light phase liquid with low density gradually moves away from the drum wall and toward the center. The clarified two-phase liquid finally enters the collection chamber through each channel and flows out along the tangent square, completing the two-phase separation. process. Features Of Centrifugal Extractor

1. Small space occupied - direct motor drive, no transmission accessories, compact structure, saving floor space and operating space;
2. Strong adaptability - compared with traditional chamber-type and tower-type extraction equipment, the stage retention time is short, phase separation is rapid, and the adaptable flow ratio range is wide; it can meet different densities and different flow ratios by replacing weir plates and frequency control. Viscosity of liquid materials;
3. High extraction efficiency - phase equilibrium is established quickly, making it easy to realize single-stage or multi-stage series counter-current or cross-flow washing and extraction;
4. Good operating performance - fully automatic operation, can run continuously without interruption, and can also be used in small batches and multiple varieties;
5. Low investment cost - the internal volume of the machine is small, and the consumption of extraction agents, solvents or detergents is minimal;
6. Good sealing performance - meets the application environment and GMP specifications for explosion-proof and toxic, harmful and volatile media;
7. Multiple optional configurations - According to different needs, the machine can be equipped with an anti-emulsification device, a cleaning-in-place (CIP) mechanism, a frequency converter, etc.
