Industrial Decanter Centrifuge for Sludge Dewatering and Solid Liquid Separation

Description

Decanter centrifuge descriptions

DAGYEE decanter centrifuge is a continuous solid liquid separation equipment designed for high efficiency sludge dewatering and industrial separation applications. The horizontal bowl design generates high centrifugal force to separate fine solid particles from liquid with minimal operator intervention. Available in two phase solid liquid separation and three phase liquid liquid solid separation configurations to meet diverse industry requirements including municipal wastewater treatment chemical processing food and beverage production edible oil refining and mining slurry dewatering.

Experience maximum solid-liquid separation efficiency

DAGYEE decanter centrifuge delivers maximum separation efficiency through advanced engineering and precision manufacturing.

• High G Force Bowl speeds generate up to 3000 G centrifugal force capturing fine solid particles down to 5 microns

• Dry Solids Output Produces sludge cake with 20 to 35 percent dry solids significantly reducing disposal volume and cost

• Clear Liquid Discharge Optimized weir plate design and liquid level adjustment produce clear separated liquid meeting discharge or reuse standards

• Continuous Operation Automatic 24/7 operation without filter cloths or pressing elements eliminates cleaning downtime and reduces labor cost

• Low Polymer Consumption Patented feed zone design reduces flocculant usage by 15 to 20 percent compared to conventional centrifuges

How does a decanter centrifuge work?

Working Principle Step by Step

Step 1 Feed Entry
Slurry enters the machine through a stationary feed tube into the mixing zone where flocculant can be added for optimal solid liquid separation.

Step 2 High Speed Rotation
The bowl rotates at high speed typically 2000 to 4000 RPM generating strong centrifugal force that pushes heavier solids outward against the bowl wall.

Step 3 Solids Settlement
Solid particles settle and compact against the bowl inner wall while lighter liquid forms an inner layer closer to the rotation axis.

Step 4 Scroll Conveying
The scroll rotates at a slightly different speed differential speed pushing settled solids toward the conical discharge end.

Step 5 Dry Solids Discharge
Dewatered solid cake discharges continuously through solids outlet ports at the conical end of the bowl.

Step 6 Liquid Overflow
Separated clarified liquid flows over adjustable weir plates and discharges through the liquid outlet at the opposite end.

Step 7 Three Phase Separation Optional
For three phase configuration liquid liquid separation occurs simultaneously with heavier liquid water discharging near the solids outlet and lighter liquid oil discharging at the opposite end.

Decanter centrifuge advanced operation capabilities

Smart Process Control

DAGYEE decanter centrifuge integrates advanced operational features for optimal performance under varying feed conditions.

Automatic Differential Speed Control
The VFD driven gearbox continuously adjusts scroll differential speed based on solids loading maintaining consistent cake dryness even when feed concentration fluctuates.

Torque Monitoring System
Real time scroll torque monitoring alerts operators to solids overload conditions before equipment damage occurs enabling proactive process adjustment.

Vibration and Temperature Sensors
Continuous monitoring of bearing temperatures and bowl vibration levels provides early warning of potential issues reducing unplanned downtime.

Remote Operation Ready
Control system can integrate with plant SCADA network enabling remote monitoring start stop control and fault diagnosis from central control room.

Multi Material Flexibility
Quick adjustment of bowl speed feed rate and differential speed allows same machine to handle different sludge types from primary sludge to digested sludge to industrial waste.

Energy Optimization Mode
VFD automatically reduces bowl speed during low load periods saving energy while maintaining minimum required separation efficiency.

Data Logging and Reporting
Optional data recorder captures operational parameters including power consumption feed solids discharge solids and runtime for performance analysis and regulatory reporting.
