ABSTRACT:
A multiple hydrocyclone assembly includes a closed tubular vertical housing enclosing two concentric vertical cylinders which cooperate with the housing to define an inner cylindrical outlet chamber and concentric annular inlet and outer outlet chambers. Multiple hydrocyclones or cyclonettes are mounted in axially extending vertical rows and in corresponding radial positions in the cylinders from the outer surface of the outer cylinder, and the housing and concentric cylinders are formed in sections which are coupled together in end to end relation. Individual cyclonettes can be removed and replaced after removal of one or more of the housing sections. In order to increase the pressure of the feed stock to be cleaned which is supplied to the cyclonettes in the upper portion or sections of the assembly, vertically extending flow channels are provided in the lower portion of the inlet chamber by omitting cyclonettes from the rows in the lower sections of the assembly.
