Working Principle of a Tubular Centrifuge
A tubular centrifuge is a vertical, high-speed separation device. A motor drives a high-speed rotating separation drum (drum) to generate a powerful centrifugal force field, separating liquids from solids and liquids from liquids.
Operating Principle:
Feed
The mixed liquid enters the bottom of the drum through the feed inlet and is rapidly distributed along the inner wall of the drum during high-speed rotation.
Separation
Under the powerful centrifugal force (which can reach 16,000–21,000 g), dense solid particles are deposited on the inner wall of the drum, while layers of liquid with different densities form a ring-like distribution.
Discharge
The separated clear liquid overflows and is discharged from the top. Solid impurities require manual removal after shutdown (for experimental models) or scraping/online discharge (for industrial models).
Core Technologies:
High Rotational Speed: Drum speeds can reach 15,000–20,000 rpm
Short Settling Path: Material separation time is minimized, reducing the risk of oxidation or deterioration
Small Particle Size: Capable of separating particles as fine as 0.1–1 μm
Advantages and Highlights of Tubular Centrifuges
1. Extremely High Separation Precision
The high-speed rotation generates centrifugal forces ranging from thousands to tens of thousands of times greater, effectively removing suspended matter, microbial cells, and fine particles from emulsions.
2. Wide Range of Applicable Materials
It can process low-concentration suspensions, high-viscosity liquids, emulsions, fermentation broths, oil-water mixtures, and other liquids, demonstrating its adaptability.
3. Maintaining Product Vitality
Short residence time and closed separation minimize degradation of heat-sensitive materials during prolonged processing, preserving product viability and quality.
4. Small Footprint
The compact vertical design saves space and is particularly suitable for laboratories, fine chemical plants, and pharmaceutical plants.
5. Easy Maintenance
The relatively simple structure allows for easy disassembly, cleaning, and maintenance, making it suitable for batch production and multi-product switching.
