Used Flottweg Two-phase separation Decanter Centrifuge, sedimentation dehydration equipment

Working Principle

 

The two-phase separation horizontal screw centrifuge achieves solid-liquid separation through centrifugal sedimentation and spiral unloading. When the suspension enters the centrifuge drum, the solid phase particles with a density greater than that of the liquid phase quickly settle to the inner wall of the drum under the strong centrifugal force of the drum. At this time, the screw conveyor inside the centrifuge pushes the solid phase deposited on the inner wall of the drum to the drying area at the small end of the drum for further dehydration, and then discharges through the slag outlet. The separated clear liquid flows out from the overflow weir at the large end of the drum, thereby achieving the purpose of solid-liquid separation.

Equipment Structure Characteristics

 

The two-phase separation horizontal screw centrifuge has a compact structure and is easy to operate. Its main components include a drum, a screw conveyor, a differential, a frame and a drive device. The drum is the core component of the centrifuge, and its speed and material directly affect the separation effect. The screw conveyor is responsible for pushing the solid phase particles to the slag outlet, and its design directly affects the dehydration effect and discharge efficiency of the solid.

 

Application

 

Two-phase separation decanter centrifuge is widely used in many industries. In the field of environmental protection, it is often used for sewage treatment and sludge dehydration; in the chemical industry, it can be used for the separation of materials such as resins, metal and non-metallic minerals; in the pharmaceutical field, it can be used for the clarification and concentration of materials such as fermentation liquid. In addition, it can also be used in multiple process such as concentration, clarification and dehydration of suspension.

 

Equipment Advantages

 

The two-phase separation decanter centrifuge has the advantages of good separation effect, large processing capacity, low energy consumption, high degree of automation, etc. It can adapt to a variety of working environments and conditions and meet the separation needs of different industries.

 

Selection Considerations

 

When choosing a decanter centrifuge, the following factors need to be considered:

• Properties of separated materials: including solid particle size, concentration, viscosity and other properties. These factors directly affect the separation effect and equipment selection.
• Processing capacity: the volume of suspension that can be processed per hour, which depends on production demand and equipment processing capacity.
• Structural form: Select the appropriate structural form according to needs, such as horizontal or vertical.
• Material selection: The material of the equipment is determined according to the corrosiveness of the material to be separated, such as carbon steel, stainless steel, titanium alloy or polymer material.
