ABSTRACT OF THE DISCLOSURE The efficiency of dust removal by cyclones may, even in case of cyclones of the recycling type, be improved by providing a gap between the clean air outlet of the cyclone and a flank of its dust laden air inlet which con- nects the dust collecting chamber of the cyclone with the ambient atmosphere. Due to the dust laden "primary" air introduced through the dust laden air inlet "secondary" air will be sucked in from the ambient atmosphere. Such secondary airflow will impel the primary airflow towards the periphery of the dust collecting chamber whereby dust particles carried by the primary air will be congregated in the vicinity of the inner wall surface of the cyclone as they enter its dust collecting chamber. Thereby, the collection efficiency of the cyclone will considerably be increased since dust particles already travelling in the peripheral portion of the airflow are more readily re- moved therefrom by centrifugal forces. The energy consump- tion increases only slightly. Further improvement of the collection efficiency can be obtained by providing a pass- age in the clean air outlet opening into the dust collecting chamber since then the air is recycled from the clean air outlet into the dust collecting chamber in the form of a tertiary air with the suction of the secondary airflow.
