Dual walled dynamic phase separator
First Claim
1. A dynamic phase separator for separation of a multi-phase mixture influent, comprising:
- a housing defining a chamber divided into two regions by a non-porous inner wall disposed radially inward relative to an outer wall, a gross separation region defined between the inner wall and the outer wall, a fine separation region inside an area defined by the inner wall and a top of the chamber, an inlet defined in the outer wall for receiving in the gross separation region the multi-phase mixture influent to be separated;
a rotatable shaft disposed within the fine separation region, the shaft having a channel defined through at least a portion thereof; and
a plurality of porous disks disposed only in the fine separation region and mounted to the rotatable shaft, the disks being in fluid communication with the channel in the shaft, the disks having a substantially smooth surface to minimize turbulence during rotation and relief holes defined therein proximate the rotatable shaft.

Abstract
Separating a multi-phase mixture influent even during excessive flows of specific phases. The dynamic phase separator includes a chamber divided into two regions by an inner wall disposed radially inward relative to an outer wall. A gross separation region is defined between the inner wall and the outer wall, while a fine separation region lies inside an area defined by the inner wall and top of the chamber. Influent to be separated is fed through an inlet into the gross separation region. A plurality of porous disks are mounted to a rotatable shaft and disposed in the fine separation region. The outer and inner walls are separated by a predetermined distance sufficient to allow for adequate rotational velocity of incoming tangential flow of the influent and dwell time sufficient for natural separation of lighter phases from heavier phases within the gross separation region.
