Decanter Centrifuge Machine Used in Oilfields for Separation of Solid Sludge Oil and Water from High Viscosity Aging Oil

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.
