Used Decanter Centrifuge, Wastewater Treatment Horizontal Centrifuge

Working principle of centrifuge

 

The horizontal screw centrifuge is a spiral unloading sedimentation centrifuge, and its working principle is based on the centrifugal sedimentation principle. When the mixed sludge containing solid phase and liquid phase enters the centrifuge, in the high-speed rotating drum, due to the density difference between the solid and liquid phases, under the action of centrifugal force, the solid particles with a larger specific gravity will quickly settle to the inner wall of the drum to form a solid ring layer, while the lighter liquid phase will form a liquid ring layer. Through the differential rotation between the screw conveyor and the drum, the sludge in the solid ring layer is slowly pushed to the conical end of the drum, and after dehydration in the drying area, it is continuously discharged from the slag discharge port; while the liquid in the liquid ring layer is continuously discharged through the overflow hole at the large end of the drum, thereby achieving solid-liquid separation.

 

Equipment Features

 

• Efficient separation: The horizontal screw centrifuge has a strong centrifugal field, which can achieve efficient solid-liquid separation, and the treated sludge has a low moisture content.
• Continuous and automatic: The equipment can continuously feed, separate, wash and unload, with a high degree of automation, reduce manual intervention and improve production efficiency.
• Large processing capacity: It is suitable for processing a large amount of chemical sludge to meet the needs of industrial production.
• Compact structure: The equipment has a compact structure design, small footprint, and is easy to install and maintain.
• Strong corrosion resistance: The part in contact with the material is made of high-quality stainless steel, which has strong corrosion resistance and extends the service life of the equipment.

 

Centrifuge Advantages

 

• Improve sludge treatment efficiency: Horizontal screw centrifuge can greatly improve sludge treatment efficiency and reduce treatment time.
• Reduce operating costs: The equipment has a compact structure, occupies a small area, and has low operating and maintenance costs; at the same time, it has a high degree of automation, which reduces labor costs.
• Improve the operating environment: fully enclosed processing, no odor emission, improve the operating environment and protect the health of workers.

Application

 

Chemical sludge treatment decanter centrifuges are widely used in the field of sludge treatment in the chemical industry, including but not limited to the following scenarios:

• Chemical production: Dehydration of sludge containing solid waste liquid, reactor bottoms, etc. generated during the chemical production process.
• Environmental protection: In the environmental protection project of chemical enterprises, the sludge generated by the wastewater treatment system is deeply dehydrated.
• Resource recovery: In some chemical production processes, the treatment of sludge by decanter centrifuge can also achieve the recovery and reuse of valuable resources.
