Centrifugal solid-liquid separation device and water treatment device using same

Abstract

When a plurality of cyclones are used as a separation device of a water treatment device, there have been as many lower liquid containers as the number of cyclones, resulting in high cost. Provided is a centrifugal solid-liquid separation device including: a plurality of cyclones respectively having at least a liquid inlet, a liquid outlet, and a lower liquid port; and a lower liquid container communicating with the respective lower liquid ports of the plurality of cyclones via pipes, arranged below the plurality of cyclones, and having a drain hole in its bottom side. The lower liquid container includes a space forming portion above lower opening ends of the pipes. Also provided is a water treatment device using this centrifugal solid-liquid separation device.
