ABSTRACT:
The invention provides a cyclonic separating apparatus that includes a plurality of cyclones, each having an inlet and being arranged in parallel with one another, and a passageway arranged upstream of the cyclones for carrying an airflow to the inlets of the cyclones, wherein dividers are provided in the passageway for dividing the airflow within the passageway into a number of separate flowpaths, the number of flowpaths being equal to the number of cyclones, and wherein the cross-sectional area of each flowpath (142a), decreases along the direction of air flow. The invention also provides a method of operating a cyclonic separating apparatus (100) comprising a plurality of cyclones (104), each having an inlet and being arranged in parallel with one another, and a passageway (142) arranged upstream of the cyclones (104), the method comprising the steps of:(a) introducing a flow of dirt-laden air to the passageway (142); (b) dividing the flow of dirt-laden air into a plurality of airflow portions, the number of airflow portions being equal to the number of cyclones (104); and (c) reducing the cross-sectional area of each of the airflow portions in the direction of flow of the dirt-laden air.
