7. A cyclonic separation apparatus comprising:
-
a first separation stage comprising an upstream cyclone separator having a longitudinal axis and an outlet; a body disposed axially of said upstream cyclone separator; and a second separation stage comprising a plurality of downstream cyclone separators arranged side-by-side relative to one another in said body axially of said upstream cyclone separator, the downstream cyclone separators being arranged in a plurality of groups, each of said plurality of groups having a respective inlet; and a receptacle for collecting material separated by said groups of downstream cyclone separators, said receptacle being disposed between the first and second separation stages, wherein said first and second separation stages are arranged in fluid communication by a plurality of inlet transfer ducts, each inlet transfer duct having an upstream end and a downstream end and extending fluidly in parallel through the body from said outlet of said upstream cyclone separator to the respective inlet of the corresponding group of downstream cyclone separators, and wherein said plurality of transfer ducts extend through the receptacle to transfer fluid that has been partly cleaned by said first separation stage to the respective inlets of said groups of cyclone separators of said second separation stage.
