Abstract

An improved regenerative separating device for separating impurities from an airflow, in particular a process exhaust airflow, provides a better distribution of the airflow in an annular gap between a rotary separating unit including a plurality of filter blocks for adsorbing impurities from the airflow and a circumferential wall of a housing incorporating the rotary separating unit. The airflow inlet provided in the circumferential wall for introducing the airflow into the annular gap and a regeneration system for regenerating the filter blocks of the rotary separating unit by a regenerating stream passing through the filter blocks to desorb impurities adsorbed in the filter blocks are both positioned in the same circumferential sector of maximum 180 degrees.
