Centrifugal separator for oil water separation
2024-07-01
Common application of Centrifugal separator for oil water separationAfter chemical synthesis reaction, oil-water separation is often involved. At present, in the industrial operation process, most of the reactors are manually discharged after static stratification. This operation method is inefficient, takes a long time to operate, and manual operation is prone to errors.
After chemical synthesis reaction and oil-water separation, the solvent obtained often needs to be washed with alkali or acid to remove impurities in the solvent. The centrifugal extractor can connect several processes in a row. Improve the degree of automation.
Using a centrifugal extractor for separation can achieve continuous operation, save labor, and improve efficiency and separation effect.Working Process Of oil water centrifugal separator machine
1. Mixed mass transfer processThe 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 processThe 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.Advantages of oil water centrifugal separator1. 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.How Multiple stage liquid liquid centrifugal separator work?
In counter-current mode, the aqueous and organic phases flow in opposite directions through multiple stages. Inside each centrifugal extractor:
- Liquids are intensively mixed in a rotating mixing zone.
- The mixture enters a high-speed centrifugal separation zone.
- The two phases are quickly separated under strong centrifugal force.
- Each phase flows to the next stage in counter-current configuration.
- This design ensures maximum mass transfer efficiency and minimal solvent loss.
