Tubular Centrifuge Machine

Characteristics and Applications
Liquid liquid separation and three-phase separation: GF series cetifuges are suitable for separating two immiscible liquids or liquid-liquid solid three-phase separation containing a small amount of solid impurities. It has a high separation factor and can effectively handle emulsions with small density differences, such as transformer oil dehydration and dewaxing, biodiesel purification, coal tar purification, etc.
Widely used: In the fields of biological products, edible oil processing, sewage treatment, etc., GF series cetifuges are used for whole blood separation of plasma and blood cells, syrup clarification, oil-water separation and other processes.

Characteristics and Applications
Solid liquid separation: GQ series cetifuges are specifically designed for clarifying suspensions with small solid particles, low concentration, and high viscosity. Its drum design can handle materials with small solid-liquid density differences, such as removing impurities from traditional Chinese medicine oral liquids and purifying lubricating oils.
Efficient clarification: In industries such as biomedicine, chemical engineering, and beverages, GQ series cetifuges can replace traditional filtration equipment and achieve high-purity liquid extraction.

A hospital uses a tube cetrifuge to separate blood cells from plasma. The operation process is as follows:
Preparation: Select sterile cetifuge tubes, set the speed to 3500 rpm, and wait for 12 minutes.
Start: After starting with no load, slowly add anticoagulant blood.
Monitoring: Observe the interface between the plasma layer and the cell layer to ensure clear separation.
Shutdown: After separation is complete, remove the centifuge tube and collect plasma and cells.

A certain chemical plant uses GQ series tubular centifuges to purify lubricating oil. The operation process is as follows:
Preparation: Preheat the lubricating oil to 60 ℃ to reduce viscosity.
Start: Set the speed to 5000 rpm for 20 minutes.
Monitoring: Detect the transparency of the liquid at the oil outlet and determine the purification effect.
Shutdown: After separation is completed, discharge the waste residue and clean the drum.

Disc centrifuge and tubular centrifuge machine have similarities in their working principles, both using centrifugal force for separation, but there are differences in structure and application. The drum of a disc centifuge is equipped with a set of stacked disc-shaped components, leaving a small gap between the discs. The suspension (or emulsion) is fed into the drum through a feed pipe located at the center of the drum. When the suspension (or emulsion) flows through the gaps between the discs, solid particles (or closed phase liquid) settle onto the discs under the action of the cetifuge, forming sediment (or dense layer).

The sediment slides along the surface of the disc and separates from it, accumulating in the largest diameter part of the drum. The separated liquid is discharged from the outlet of the drum. Disc cetifuge is suitable for separating emulsions and suspensions containing small amounts of solid particles. It has the characteristics of large processing capacity and high separation efficiency, but its structure is relatively complex, and cleaning and maintenance are relatively difficult. The tube cetifuge has a relatively simple structure and is suitable for separating various difficult to separate emulsions and suspensions, especially for solid-liquid separation with low concentration, high viscosity, fine solid particles, and small solid-liquid density difference. However, the drum volume is small and requires frequent shutdown to remove sediment.

Compared with other types of cetrifuges, tube centifuges have unique advantages and applicability. For example, a horizontal spiral cetifuge is a settling device that discharges and operates continuously. It is suitable for separating and clarifying suspensions with solid particle equivalent diameter ≥ 3 μ m and concentration range of 2% -40%, as well as for separating emulsions with a wide particle size distribution range. Tube cetifuges are more suitable for situations that require high separation accuracy and special material properties. When choosing a cetifuge, it is necessary to comprehensively consider specific separation requirements, material properties, processing capacity, and other factors to select the most suitable cetrifuge type.
