Outstanding and Continuous Decanter Centrifuge 3 Phase Decanting Machine
Description
3-phase decanter is also called tricanter, the typical application is for the Treatment of Oily Waste Water.
The processing of crude oil in refineries and petrochemical plants creates oil contaminated waste water. Processing this waste water signifies
separating the waste water into its main components consisting of oil, water and solids. Due to the increasing significance of oil, the objective
lies in recovering as much oil as possible and in disposing other components like water and solids in an efficient way.
The Tricanter performs a three-phase separation, i.e. the simultaneous separation of two immiscible liquids with different densities and one solid phase, provided that the solid phase is the heaviest phase. The main difference from a decanter is the separate discharge of the two liquid phases
It is a popular machine throughout the world and is also widely used in other fields, such as fish oil, palm oil, kitchen waste oil separation etc.
Working priciple
The tricanter discharges the heavy liquid through an adjustable impeller under pressure and the light phase by gravity. The variable impeller allows for precise on-the-fly adjustment of the pond depth and the liquid-liquid separation zone.This optimizes the purity of the liquids and may eliminate downstream equipment.

Separation principle
The decanter is driven by two motors. The main motor drives the bowl and the housing of differential mechanism to rotate through belt, while the auxiliary motor drives through the belt pulley the input shaft of the differential mechanism to rotate, which, after speed change, drives the helical to rotate. In this way the bowl and helical rotate in the same direction but with certain differential speed.
When the material to be processed (blended liquid consisting of solid phase and liquid phase) enters the inner cavity of the helical propeller through feeding pipe, after being accelerated by the two-way conical accelerator, it flows out of the material outlet, and flows into the bowl wall through inner cloth cylinder. The light, heavy and residue phases that make up the suspending liquid, under the action of different centrifugal force, the residue phase quickly subsides onto the inner wall of the bowl, and the heavy phase adheres close to the surface of the residue phase rather slowly, while the light phase adheres close to the surface of the heavy phase rather slowly, forming a dividing plane between the two phases. As the sedimentation of heavy phase increases, the top end of helical blade enters into the sedimentation layer of heavy phase. At this time the bowl and helical propeller are rotating in the same direction at high speed and with a certain difference in speed. This relative difference in rotation speed enables the helical to propel heavy phase particles to move toward the material outlet at the small end, whereas the light phase, through the helical passage, flows toward the liquid phase outlet at the large end, and flows out through the overflow plate with different R values.
