What is a tubular centrifuge?
A tubular centrifuge is a liquid separation device with a high-speed rotating tubular drum as its core. It is mainly used for the efficient separation of different phase components in liquid-solid, liquid-liquid or liquid-liquid-solid mixed systems. Its core component, the drum, has a small diameter (usually 105mm150mm), but a very high speed of up to 1600020000 rpm, and the centrifugal force generated can reach 15000 times the acceleration of gravity (g), far exceeding other types of centrifuges.
Brief description of features:
High separation accuracy: suitable for separating submicron particles, and can effectively separate solid impurities or emulsion phases with a particle size of less than 1μm.
Moderate processing capacity: suitable for continuous or semi-continuous separation of small batches and high value-added materials.
Compact structure: The whole machine occupies a small area and is suitable for deployment in clean rooms, small factories or laboratories.
Easy maintenance: In addition to regular cleaning, there is no need to frequently replace consumables.
Working principle details
The working principle of the tubular centrifuge is based on the law of centrifugal sedimentation. When the mixture enters the high-speed rotating drum from the bottom, the materials with different densities are quickly separated under the action of centrifugal force.
1. Liquid-solid separation:
High-density solid particles are deposited on the inner wall of the drum under the action of centrifugal force to form sediment.
Low-density liquid gradually gathers in the inner layer and is discharged from the top outlet.
2. Liquid-liquid separation:
Two immiscible liquids (such as oil and water) are separated according to the density difference in the high-speed centrifugal field and discharged from different liquid outlets.
3. Liquid-liquid-solid three-phase separation:
First separate the solid particles;
Then treat the two liquids in layers;
Finally, the three phases are collected independently.
Although this principle seems simple, it has extremely high requirements for the dynamic balance, high-speed bearings, material selection, drum thickness and drainage design of the equipment, and is one of the representatives of high-end manufacturing industry.
Comprehensive analysis of technical advantages
1. Ultra-high separation factor
The acceleration of conventional sedimentation separation is 1g, while the tubular centrifuge can reach 10000g~15000g, so that materials with smaller particle size and weaker density difference can also be separated in a very short time, greatly improving the separation efficiency.
2. Corrosion-resistant materials and high-strength structures
Our tubular centrifuges are mainly made of 316L stainless steel, titanium alloy or duplex steel, which can adapt to complex working conditions such as strong acid, strong alkali, solvent, organic alcohol, etc. At the same time, all rotating parts are dynamically balanced to ensure mechanical stability under high-speed operation.
3. Clean and hygienic design, in line with GMP standards
In order to meet the high requirements of cleanliness for medicines, biological products, etc., our equipment design adopts:
No dead angle structure;
CIP/SIP cleaning;
Internal mirror polishing to reduce residue;
Strong sealing to prevent the invasion of pollutants.
