ABSTRACT:
A cyclonic separation apparatus comprises a plurality of series-connected separation stages50,51, each comprising a plurality of cyclone separators16/23connected in parallel and disposed in a generally annular arrangement about a main vertical axis of the apparatus, with their respective longitudinal cyclone axes extending parallel to the main axis. The successive separation stages50,51in the direction of fluid flow are disposed radially inwardly of each other with respect to the main axis of the apparatus and are also vertically staggered upwardly, so that the outlet20of one separation stage50leads directly into the inlet22of the next downstream stage51. The multi-stage, series connected cyclone separators of the apparatus provide a high separation efficiency, yet the annular arrangement of the stages50,51makes the apparatus compact and enables the apparatus to be utilized in a vacuum cleaner.
