Industrial Organic Wastewater Treatment with Liquid-Liquid Centrifugal Separator

Liquid-liquid Centrifugal extractor, as a new, fast and highly efficient liquid-liquid extraction separation equipment, it is different from traditional extraction machine such as mixer settler, extraction tank. Centrifugal extractor uses  motor driving bowl to reach high speed, two liquid that different densities and  mutually immiscible complete mixing under the shear force generated by the rotation of bowl or blade, and separated rapidly under the centrifugal force generated by the rotation of bowl.

Extractor working principle:
1.Mixing and mass transfer process:
Light and heavy liquor enter in the annulus mixed zone proportionally and from two different feed pipe orifice respectively, which formed by bowl and shell, with the help of bowl's rotation, the two phases through turbine disc and impeller mixing and dispersing quickly, after mass transfer completely, to finish mass transfer process.
2.  Two phases separation process
With the eddy-current disc help, mixture enter in bowl, at the compartment formed by board, the mixture is quickly synchronized with the bowl, under the action of centrifugal force, the larger density liquor moving away from the bowl center to the wall gradually in the upward flow; and the small density liquor doing the opposite, after clarification, two liquids enter into collection chamber with their own weir plate respectively, and drawn out by tigella, to finish the separation process.

Extractor advantages:
Separation effect is obvious and large handling capacity;Two phase materials contact with short time, and save extraction agent consumption and save cost;High mass transfer rate, high stage efficiency, convenient start and stop, it can not break balance when stopped.Cover small area, the cost of comprehensive investment is low;Well-adapted, good flexibility, with intermittent operation, or single operation, or continuous counter current operation, and there is no need to add interstage pump.
Centrifugal Extractor Specification:
1. Equipment material will be chosen according to the feed physico-chemical property, common used SS304/316L/904L, common composite material, fluoride material and so on;
2. Above table is general parameter, real device has a little difference, please refer to the matched technological manual;
3. Above flux is under ideal condition, ratio of oil and water is their flux sum when 1:1.

Liquid-liquid extractor application:

1. Oil water separation( crude oil/heavy oil/diesel and so on except water, salt);
2. Pharmaceuticals( such as used for ethyl acetate, methylene dichloride, normal butanol, choroforom and so on);
3. Extraction of chinese traditional medicine;
4. Pesticide(malathion extraction and so on);
5. Bioengineering(nutrient solution extraction and interferon extraction and so on);
6. Chemical and fine chemical( catalyst extraction and so on);
7. Hydrometallurgy( used mutilstage extraction and back extraction and so on to extract nickel, copper, uranium and other rare metals);
8. Food( edible oil, spice, refined oil, food color and so on);
9. Perfume industry;
10.Printing and dyeing industry( printing and dyeing wastewater treatment and recycle);
11.Environmental protection( used multistage extraction and back extraction and so on technology to treat wastewater with phenol, oil-water separation of marine sewage, groundwater separation or extraction or purification and so on);
12. Cosmetics industry( to extract nutrient ingredient);
13. Liquid/two gas phase separation( to remove bubble in liquid phase and so on).
