Sedimentation type solid-liquid separator

摘要

The slurry subjected to aggregation processing by a line mixer is supplied to a slurry feed member (3) via a slurry supply passage (2) and then fed radially outward from slurry fed outlets (17) within a sedimentation tank (1). Therefore, liquid flow hardly takes place below the slurry feed member (3) and the settling velocity of the solid is increased. The slurry feed member (3) is arranged close to the boundary face (L1) of the thickened slurry zone, and thus the settling distance of the solid is shortened. Accordingly, the residence time of the solid is shortened to a great extent. In addition, the sedimentation tank (1) can be constructed to be sealed and solid-liquid separation can be also performed under the pressurized state. IMAGE
