Project Overview
At a major coal tar processing facility, the ZK LW series decanter centrifuge was implemented to address complex separation challenges. The system effectively processes coal tar sludge—a difficult mixture of water, oil, and solid particles—to achieve efficient three-phase separation. This high-performance decanter not only delivers exceptional oil recovery rates but also produces clear water suitable for reuse or discharge, significantly reducing both operational costs and environmental compliance hurdles.
- Feed material: coal tar sludge with water content, containing oil and solid particles
- Objective: maximize oil recovery, reduce water content, and minimize disposal costs
- Solution: ZK LW series 3-phase decanter with specialized wear protection
System Configuration
-
Feed Preparation & Heating
Coal tar sludge is preheated to optimal temperature for improved flow characteristics and separation efficiency. Temperature control ensures consistent processing conditions.
-
ZK LW Series 3-Phase Decanter
Specialized 3-phase decanter with enhanced wear protection for abrasive coal tar particles. Optimized bowl and scroll design for maximum oil recovery and water clarity.
-
Automated Control System
Integrated PLC/HMI monitors differential speed, torque, and flow rates. Automatic adjustment ensures optimal separation performance under varying feed conditions.
Performance Highlights
- High oil recovery efficiency exceeding 95%
- Clear water discharge with minimal oil content
- Reduced disposal costs through effective separation
- Robust construction for harsh coal tar environment
- Low maintenance requirements with easy wear part replacement
