The working process and separation efficiency of the centrifuge water treatment

Jul 17, 2019

A centrifuge water treatment is a device that performs a decanting operation. A decanter that performs a decanting operation by gravity is called a settling tank; a decanter that performs a decanting operation by centrifugal force is called a centrifugal sedimentation machine. The decanter is divided into two types of batch operation and continuous operation, and sometimes only the continuous centrifugal sedimentation machine is called a decanter.


The centrifugal decanter is mainly a device for continuously separating the raw liquid into a filter cake and a filtrate during the working process. At 1100-2000 rpm, its powerful centrifugal force separates and licks the fine particles onto the wall of the separator, and the filter cake is discharged from the discharge port through an internal screw conveyor.


When the centrifugal decanter supplies the raw liquid, the torque is affected by not increasing the concentration of the raw liquid, and the flow rate is varied with the concentration by the automatic regulating valve. The isolation of cells from microbial fermentation broth is an important unit of the fermentation industry. It belongs to a non-Newtonian type fluid [showing a viscosity of 10-200 (centipoise)], and it is difficult to perform solid-liquid separation using a general filtration method (using a plate and frame filter press, a vacuum drum filter, etc.) and it is difficult to separate.


The decanter full-scale spiral discharge sedimentation centrifuge is a separation machine with high solid-liquid separation efficiency, large processing capacity and continuous operation. In recent years, separation operations for antibiotics, vitamins, citrate, starch, and the like have begun.
