Decanting Centrifuge used in oil industrial

Decanting centrifuge is one type of the screen centrifuge which belongs to the industril centrifuge. It is used in many industrial applications. During the solids control system matching to the drilling rig system, decanter centrifuge is a piece of equipment that is used as the fourth class solids control equipment. Decanting centrifuge design consists of a solid container, called a bowl, which rotates at high speed. Inside the bowl tube, a screen conveyor rotates in the same direction, but at a slightly different speed. A differential gear is typically used to adjust speed.

Decanting Centrifuge Working Priciple
Decanting centrifuge is generally driven by an electric motor, that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. The centrifuge works using the sedimentation principle, where the centripetal acceleration causes more dense substances to separate out along the radial direction. By the same token, lighter objects will tend to move to the top.

How Dencanter Centrifuge Works
The drilling slurry is fed through a stationary pipe, which is inside a hollow shaft connected to a screw conveyor or scroll. The slurry enters a feed compartment located inside of the conveyor and is forced through discharge nozzles to the bowl section. Once inside the bowl, centrifugal force makes the material to separate. The screw conveyor moves the solids to the tapered end where they are discharged. Pure fluid flows out the other end.

Dencanting Centrifuge
According to the rotary speed, decanting centrifuge could be classified to middle speed decanting centrifuge, high speed decanting centrifuge, and high speed variable frequency decating centrifuge, mainly separate 2-7 microns particle out.
