Industrial Centrifuge Applications
The industrial centrifuge’s main application functions are dewatering, clarification, concentration, classification, separation, etc.
Simultaneously, Compared with other separation machinery, the industrial centrifuge can obtain a solid phase with low moisture content and a high-purity liquid phase and has the advantages of small footprint, good sealing, continuous operation, automatic remote control, etc.
Industrial centrifuges can be used in various industrial production-related industries such as chemical, petrochemical, oil refining, medicine, food, coal, mineral processing, and environmental protection.
However, different industries have different material characteristics and separation requirements for centrifuges. Therefore, when targeting specific industries, we need to choose different types of industrial centrifuges. Only in this way can we simplify the process and reduce energy consumption. While ensuring the improvement of product quality, good economic benefits have also been achieved.
This type of centrifuge is widely used in paper mill sewage, printing and dyeing plant sewage, coal washing water (commonly known as gray water), neutralization wastewater, power plant wastewater, purification water station wastewater, industrial cooling wastewater.
Types of Different Industrial Centrifuge
There are many types and specifications of industrial centrifuge. According to the separation principle, they are classified as filtration centrifuge and sedimentation centrifuge.
Filtration centrifuge group are divided into pusher centrifuge, screen scroll centrifuge, conical basket centrifuge, vibratory centrifuge, screen bowl decanter centrifuge, vertical basket centrifuge, peeler centrifuge, inverting filter centrifuge, etc.
The sedimentation centrifuges include: solid bowl decanter centrifuge, disc bowl centrifuge, tubular centrifuge, imperforate basket centrifuge, tubular centrifuge, etc., each type also has different specifications. The suitability of the separation factor of different centrifuge models to the material, the solid phase moisture content and the liquid phase clarity after separation are also different.
Therefore, how to choose an appropriate centrifuge is very important for certain material separation requirements.
Processing Material Characteristics
The efficiency of the separation process such as dewatering, clarification, concentration, classification, and separation is not only related to the choice of the centrifuge type, but also related to the characteristics of the separated material, that is, the characteristics of the suspension, the characteristics of the solid particles, and the characteristics of the emulsion.
Suspension refers to a system composed of liquid and solid particles suspended in it. According to the size and concentration of solid particles can be divided into: coarse particle suspension, fine particle suspension, high concentration suspension and low concentration suspension.
The size of the solid particles, the concentration of the suspension and the growth rate of the thickness of the filter residue or the sediment are closely related to the processing capacity of the industrial centrifuge, and they play an important role in the selection of equipment.
Characteristics of Solid Particles in The Suspension
The characteristics of solid particles generally refer to the main physical properties of the particles in the particle group, including particle size, particle size distribution, shape, density, and surface properties.
They are closely related to separation performance.
- 1. The solid particles in the suspension or slurry are a mixture of many single particles and clusters of particles.The size and geometric shape of the particles are related to the interaction between the surrounding liquid surface. The smaller the particle, the greater the surface area, thus the more significant surface effect between solid and liquid.
- 2. Some particles are easy to separate due to strong crystallization force or intermolecular attraction, particles and liquids have distinct interfaces, such as metal powder, sand grains and some salt products. Some particles, such as silicic acid, clay, aluminum hydroxide, and iron hydroxide, have no distinct interface between the particles and the liquid, making it difficult to separate.
- 3. Particles can be divided into two types: hard and soft and brittle. Hard particles are relatively stable, and soft and brittle particles may break and reduce the particle size during transportation, stirring, mixing, and agglomeration, thereby affecting solid-liquid separation.
It is recommended to consult specialized centrifuge manufacturers such as ZK Separation for design and application details.
