Three Phase 440V Decanter Centrifuge SS2205 Specially For Aging Oil Treatment
The three-phase separation decanter centrifuge is a fully enclosed, fully automatic and continuous process for the treatment of aging oil. This product has been successfully used in Daqing Oilfield and Liaohe Oilfield.
The aging oil from the storage tank has a high viscosity due to a long deposition time, so it must be heated and a demulsifier added to reduce the viscosity. The aged oil enters the three-phase decanter centrifuge through the pump, and the centrifuge rotates at a high speed. Under the action of a large centrifugal force, the solid (sludge) with high density settles on the drum wall. Two liquid phases with different densities form concentric cylinders, with the lighter liquid phase (oil) in the inner layer and the heavier liquid phase (water) in the outer layer. The thickness of different liquid rings can be adjusted by the liquid adjusting plate. The sludge deposited on the drum wall is conveyed by the screw conveyor to the cone end of the drum body, and discharged from the discharge port. It can be transported to the designated place by the conveyor belt. A trolley can also be used to transport sludge. The separated oil is transported to the storage tank through the oil discharge pipeline, and the separated water is also discharged through the drainage pipeline.
Working principle :

Other Applications :
The 3-phase decanter separates which contains oil into an oil phase, solids and virtually oilfree waste water. Because of its high dry matter, the solids can be recycled relatively easily.
In addition, the solids concentration in the waste water is lower than would be the case if nozzle separators are used in conventional process.
Advantages :
1. Lower cake transportation costs due to very dry solids
2. Better recovery of nutrients due to very high separation efficiency
3. Lower fresh water consumption compared to other processes
4. Continuous and fully automatic operation
5. 24 h operating reliability
6. Optimum wear protection
7. Energy saving design
8. Easy to operate
9. Easy to maintain
10. Simple assembly/dismantling
Features :
- All parts coming into contact with the product are made of stainless steel.
- 3-phase AC motor for controlled torque starting via frequency converter
- Approximately 80 to 90 % of the oil is recovered.
- Low personnel costs due to continuous and automatic operation.
- Highest g-force for higher solids output
- Adjustable bowl speed via VFD
- Automatic adjustment of differential speed via VFD
- Two motor drive
- Belts for both primary motor and secondary motor
