ABSTRACT:
A centrifuge, for separating a fluid feed into two fluids, includes a rotor shaft and a rotor housing within which is a set of concentric, equal spaced cylindrical shells providing elongated annular chambers for parallel flows of fluid. Distributor means extends radially from the shaft within one end housing portion to furnish fluid separately to the chambers. One collector means to receive one separated fluid extends radially from the shaft within the other end housing portion to communicate with the chambers. A second collector means is located preferably at the same transverse plane passing through the shaft by using radially extending walls within that end portion of the housing to divide it into a number of pie-shaped chambers, each having an outlet adjacent the shaft. Each collector means includes some of these pie-shaped chambers. In the broadest construction the total area of a set of openings of the distributor means (or of one of the collector means when appropriate) communicating with a specific annular chamber is proportional to a value between about the third power and about the fourth power of the average radius of the annular chamber. There are outlet pipes communicating with the two collector means and one of the pipes is valved to control the volume ratio of removed fluids.
