Oil recovery from oil sludge
Industrial oily waste water
Sedimentation ponds and lagoons
Tank cleaning
Applications
The decanter SOLW Series from Huading Separator is a continuously operating horizontal solid wall centrifuge, which are special designed for oily waste water treatment. Processing this oily waste water means separating it into its main components of oil, water, and solids. The objective is to recover as much oil as possible and to dispose of the other components in an efficient way.Including oil and sewage sludge treatment, recovery oil from lagoons and sedimentation ponds, as well as recovery oil from residuals during tank cleaning.
Features
1. All parts coming into contact with the product are made of stainless steel.
2. 3-phase AC motor for controlled torque starting via frequency converter
3. Approximately 80 to 90 % of the oil is recovered.
4. Low personnel costs due to continuous and automatic operation.
5. Highest g-force for higher solids output
6. Adjustable bowl speed via VFD
7. Automatic adjustment of differential speed via VFD
8. Two motor drive
9. Belts for both primary motor and secondary motor
Working principle of centrifuge separator
Drum and screw are working with higher speed at a certain differential rotation. Material is transported into spiral tube continuously , accelerated after the rotary drum, in under the action of centrifugal force field, the heavier solid deposit formed in the drum wall sediment layer.The feeding screw continuously pushes the solid phase of the deposit to the drum cone, and then out of the drain.The lighter liquid phase forms the inner liquid ring, which is continuously overflowed by the large end of the drum, and is discharged through the drain outlet.The machine operates at full speed, continuously feeding, separating, washing and discharging.It has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity and convenient maintenance.It is suitable for the suspension with solid phase particle size greater than 0.005mm and concentration range of 2-40%.Widely used in chemical industry, light industry, pharmaceutical, food, environmental protection and other industries.
HOW DOES IT WORK
With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.
Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the production of biodiesel .
Product advantage
1. Clean appearance
2. No more odour problems
3. Easy to install and operating equipment
4. Small footprint
5. Operate for different sludge types
6. Operating for thickening or dewatering
7. Reduced labour costs
8. More process flexibility and higher levels of performance
WHAT IS CENTRIFUGE DECANTER
When you need to separate solid / liquid mixtures with high solids content, you can choose a decanter centrifuge. In contrast to chamber filter presses, these solid vortex centrifuges or decanter centrifuges operate continuously. High centrifugal forces separate finely divided solid particles from the suspension.
Our decanter centrifuges are modular in design and can be used in a wide range of industries. Centrifuges can be optimally adjusted for specific applications. Applications range from sludge dewatering to classification or wet classification to solid classification.
