With the advancement of the national “dual carbon” strategy and the continuous improvement of environmental protection standards, industrial enterprises have put forward higher requirements for solid-liquid separation and treatment of wastewater, sludge, waste residue, etc. As the current mainstream automated solid-liquid separation equipment, the decanter centrifuge has been widely used in municipal sewage, chemical pharmaceuticals, food processing, mining and smelting, oil drilling and other fields with its advantages of high efficiency, continuous operation, intelligent control, and small footprint.
As a professional decanter centrifuge manufacturer in China, we are committed to providing customers with high-performance, high-stability, and cost-effective separation solutions. Multiple dimensions, systematically introduce the advantages and value of the decanter centrifuge.
How does a decanter centrifuge achieve efficient solid-liquid separation?
Decanter centrifuge is a continuous device that uses a centrifugal field to separate solids and liquids. The device consists of a drum, a screw conveyor, a differential system, a frame, a motor and a control system. Its working principle is as follows:
High-speed rotation generates centrifugal force
The drum rotates at a high speed (usually 1500~4000 rpm), forming a centrifugal field with thousands of times the acceleration of gravity inside the drum, so that the solid and liquid phases with different densities are quickly separated.
Screw conveying achieves solid discharge
The screw conveyor, which is coaxial with the drum but rotates at a slightly lower speed, continuously pushes the solid particles deposited on the drum wall to the slag outlet to achieve continuous slag discharge.
Liquid is discharged through the overflow port
The clarified liquid after separation is discharged from the equipment through the overflow weir to achieve continuous separation processing.
Main technical features:
Continuous feeding, continuous separation, continuous slag discharge
Adjustable differential speed to achieve fine control under different working conditions
Horizontal structure, low center of gravity, stable operation
Closed structure to reduce odor leakage and secondary pollution
Multi-scenario application of decanter centrifuge
Decanter centrifuge is suitable for almost all industries that require solid-liquid separation. According to material characteristics, separation requirements and processing scale, we provide a variety of model customization services.
1. Municipal sewage treatment
Applied to urban sewage treatment plants and rural sewage centralized treatment facilities
The moisture content of the separated sludge is as low as 70%-80%
2. Industrial wastewater/sludge treatment
Waste liquid dehydration in petrochemical, electroplating, papermaking, printing and dyeing industries
Provide personalized configuration for high-viscosity, highly corrosive, and highly abrasive materials (such as duplex steel, tungsten carbide spraying)
3. Food and beverage industry
Used for separation of fruit and vegetable juice, starch slurry, soy milk residue, etc.
4. Oilfield drilling and mine tailing
