Description Of Liquid liquid centrifugal separator

Liquid liquid centrifuge is a new, fast and efficient liquid-liquid extraction and separation equipment. It has higher separation efficiency than traditional extraction equipment such as mixer settler and extraction towers, and is more conducive to continuous production.

Liquid liquid centrifuge a motor to drive the drum to rotate at high speed. The two liquids to be mixed and separated complete the mixing and mass transfer under the action of the shear force generated by the stirring paddle, and then are quickly separated under the action of the centrifugal force generated by the high-speed rotation of the drum.

Liquid liquid centrifuge can be used as a single unit or can be connected in multiple stages to achieve counter-current extraction. It has high mass transfer efficiency, short two-phase residence time, low retention volume, and is easy to operate. The rotation speed, flow ratio and mixing intensity can be changed as needed.

Working principle Of Liquid liquid centrifugal separator

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 Continuous liquid liquid centrifugal separator

• Simple and stable structure: top-suspended structure, no bottom bearings, and no risk of leakage;
• High extraction efficiency: the independent mixing chamber and stirring paddle can be replaced according to the requirements of the mixing system;
• Energy saving: non-annular mixing structure, the drum itself does not participate in mixing, low energy consumption and can effectively avoid the emulsification phenomenon caused by over-mixing;
• Corrosion resistance: The material can be made of stainless steel metal materials or non-metallic composite materials;
• Good sealing performance: multi-channel shaft seal design, optional magnetic transmission structure.

 
Application Field Of Liquid Liquid centrifugal separator

1.    Wastewater treatment (such as phenolic wastewater treatment, waste acid water treatment);
2.    Pharmaceutical industry (such as preparation of pharmaceutical intermediates, Chinese medicine purification);
3.    Hydrometallurgy industry (such as copper, vanadium, nickel, rare earth elements and so many elements’ extraction and separation);
4.    Food industry (such as edible oil, food pigment, additive, lactic acid, citric acid and other extraction or separation);
5.    Fine chemicals (such as spice extraction, raw material of cosmetics extraction, vanillin extraction);
6.    Oil-water separation (such as remove water from crude oil/heavy oil/diesel and so on);

Remarks：
1. Equipment materials need to be selected based on the physical and chemical properties of the materials being processed. Commonly used materials include polymer composite fluorine materials, SS304, SS316L, ordinary composite materials, fluorine materials, etc.
2. The mixing flux in the technical parameter table of each model mentioned above is the maximum theoretical flux of the equipment. The actual processing capacity of the equipment depends on the system of the material liquid (such as density, viscosity, emulsification degree, etc.), mass transfer efficiency, and separation effect. etc. are closely related.
