The disc centrifuge separator is specially used for the two-phase and three- phase separation. The two-phase separation is to separate the suspended solid from liquid or two liquids which have the different specific gravity and are immiscible. The three-phase separation is to separate the two immiscible liquid phases and a phase of solid at the same time.
Inside the drum is a set of disc-shaped parts, which are nested and folded together. There is a small gap between the discs. The suspension (or emulsion) is added to the drum by the feed pipe at the center of the drum. When the suspension (or emulsion) flows through the gap between the discs, the solid particles (or droplets) settle on the discs under the action of the centrifuge to form sediment (or liquid layer). The sediment slides along the surface of the disc and separates from the disc and accumulates in the place with the largest inner diameter of the drum. The separated liquid is discharged from the outlet of the drum.
The function of the disc is to shorten the settling distance of solid particles (or droplets) and expand the settling area of the drum. The disc installed in the drum greatly improves the production capacity of the separator. The solid accumulated in the drum shall be removed manually after the separator is shut down, or discharged from the drum without shut down through the slag removal mechanism.
There are two operations of disc centrifuge:
1. Liquid solid separation (i.e. separation of bottom concentration suspension), which is called clarification operation, that is two-phase separation.
2. Liquid-liquid separation (or liquid-liquid-solid) separation (i.e., the separation of emulsion) is called separation operation, that is three-phase separation.
The disc separator is specially used for the two-phase and three- phase separation. The two-phase separation is to separate the suspended solid from liquid or two liquids which have the different specific gravity and are immiscible. The three-phase separation is to separate the two immiscible liquid phases and a phase of solid at the same time.
This automatic discharging separator has the traits as high rotating speed, operating stability, completely sealed up of the inlet and outlet system, lower noise and fine separating effect. Centripetal pump system designed by our professional designer has the traits as stable outlet pressure, large regulating sphere and operating easily. It has professional automatic domination case with safety protection device and advanced automatic vibrating testing instrument which can view vibrating number at any time. We can make the best separating and discharging by adjusting separating parameter directly at the screen.
