Abstract
A continuous centrifugal separator (CCS) system provides a laminar, annular, velocity distribution (LAVD) throughout, using axially staged and radially staged distribution of incoming flows. Diffuser plates help establish the LAVD at comparatively low (stably laminar) Reynolds numbers in axial flow through a trapezoidal (trapezoid of rotation) rotor shell. Dynamic cleaning (during uninterrupted operation) by feedback control of fluid and system conditions (e.g., turbidity, vibration) may be set and reset by feedback control. Static cleaning removes deposits not flushed by dynamic cleaning. A coalescence plate encourages collapse of the dispersion band to a thin boundary between separated species at a central radius optimized by operating parameters, such as mass flow rate and rotational velocity.
