ABSTRACT:
An apparatus which serves to clean air containing fine dust and also larger particles, such as fibrous material, thread ends, etc., which are produced in an industrial environment, especially a textile plant. In order to conduct a two-stage cleaning process without the necessity of dimensioning two filtering stages for the full air flow, there is provided a vortex chamber into which the unclean air is admitted tangentially or in some manner which produces a rotary flow with centrifugal force components which act on the larger particles in the air stream. The vortex chamber includes a rotating filter drum, the interior of which may preferably be provided with suction, causing air to flow from the vortex chamber through the filter, depositing thereon the fine dust carried by the incoming air. The clean air is conducted out of the apparatus through a clean air outlet while the larger contaminants are conducted out of the vortex chamber through a separate outlet by a relatively small fraction of the total air flow.
