How does Decanter Centrifuge Work?

Decanter Centrifuge

Introduction: Decanter centrifuge is a very common equipment that is often found in an oil or gas drilling site. A decanter centrifuge is a very important machine for oil and gas drillers. A decanter centrifuge is basically used to dilute the underground fluids and liquids.

The main job of a decanter centrifuge is to rotate the drilling fluids and in doing so breaking the concentration of those fluids. The whole working functions of any decanter centrifuges is pretty much complex. Here is a discussion given below about how a decanter centrifuge works.

The way a decanter centrifuge works:  As it is mentioned before the process of a decanter centrifuge is a bit complex. Usually,  decanter centrifuges depend on sedimentation, differential speed and G force to perform its job. A decanter centrifuge needs a centrifugal force in order to loosen the fluid.

The sedimentation rate is an important feature for the centrifugal process. If the G force or centrifugal force is very high, the separation process becomes very easy and effective. The size and shape of particles and their level of concentration determine the sedimentation rate of any decanter centrifuge.

The sedimentation rate also depends on the centrifugal force. Another important issue for the functionality of decanter centrifuges is the differential speeds. In a centrifuge two different parts rotate simultaneously. The first part that rotates is the exterior bowl and the second part that rotates is scroll conveyor. Sedimentation is gathered in the centrifugal cylinder as the result of varying speed of the two above mentioned separate parts.

If the differential speed of decanter centrifuges is too high, a little time is required to loosen up the concentration of waste fluids. So, it is very important to keep the differential speed of a decanter centrifuge minimal. Thus, a decanter centrifuge operates its functionalities.

What are the Principles of Decanter Centrifuge of Kosun

Decanter Centrifuge

Decanter centrifuge separates the solid material mixed with some liquids that contaminates the water and converts the mud into sludge. It is an important component utilized in petrochemical, food processing and oil industries. These industries will not be able to function in the absence of Centrifuge. The centrifugal force is created by the decanter centrifuge and creates the centrifugal force by rotation.

Operational & Functional Principles of decanter centrifuge:
•    The principle of decanter centrifuge is based on the theory of gravitational separation. A component with high density settles at the bottom and the component with lesser density suspends upwards.

The decanter centrifuges increases the rate at which the component settles increases due to the use of continuous rotation. This force is from 1000 to 4000 times than the normal gravitational force. This method of separation gives fast results.
Example: When a glass is filled with mud and water, after few minutes the mud will settle at the base of the glass due to its weight. Since the mud is settled at the base become solid, the water comes upward that creates a separation between the mud and water mixture.

This method of separation by rotation can be compared to that of rides of amusement parks. In the same way the decanter centrifuges basically a bowl tube rotates at a very high speed. The bowl tube has an internal conveyor that moves at different velocity but in the same direction.

The decanter centrifuge is ideal equipment for treating waste water. There are various industries where these types of machines are vital.

The 2-phase separation method is used for Waste water treatment, sludge de-watering, and also food processing.

The 3-phase separation process separates two liquids like water and oil, which have different densities and cannot be mixed together, are separated. This 3-phase separation produces edible oil, bio-diesel and oil sludge.
