Centrifugal effect and density of oil water separator centrifuge

- Mar 01, 2019-

The oil water separator centrifuge is mainly used for centrifugal force, which is a machine for separating liquid and solid particles or liquid and liquid, and the oil water separator centrifuge has a cylinder rotating at a high speed around its own axis. It is called a drum and is usually driven by an electric motor. After the suspension (or emulsion) participates in the drum, it is agilely driven to rotate at the same speed as the drum, and the components are separated under the action of centrifugal force, and the discharge is discriminated.

The principle of the oil water separator centrifuge is that there are two kinds of centrifugal filtration and centrifugal sedimentation. During the operation, the centrifugal filtration is a centrifugal pressure that can make the suspension occur under the centrifugal force field, and acts on the filter medium to make the liquid pass through the filter medium to become a filtrate. The solid particles are trapped on the surface of the filter medium to achieve liquid-solid separation. The centrifugal sedimentation is the principle of agile sedimentation and stratification in the centrifugal force field by using different concentrations of suspension (or emulsion) to achieve liquid-solid. (or liquid-liquid) separation.

The oil water separator centrifuge is placed under a dense object, and the object with a lower density is on. When the suspension containing fine particles is still in operation, the suspended particles are gradually formed due to the action of the gravity field. sink. The heavier the particles, the faster the sinking, whereas the particles with a lower density than the liquid will float. The rate at which particles move under the gravitational field is related to the size, morphology, and density of the particles, and is related to the strength of the gravitational field and the viscosity of the liquid. Particles of the size of red blood cells, a few micrometers in diameter, can be observed under normal gravity.
