1. A regenerative separating device for separating impurities from an airflow, in particular a process exhaust airflow, comprising:
a rotary separating unit defining a radial direction and a circumferential direction, and comprising a plurality of filter blocks for receiving impurities from an airflow passing through said filter blocks in said radial direction;
a housing for incorporating said rotary separating unit with an annular gap between a circumferential wall of said housing and said rotary separating unit, wherein said housing has an airflow inlet provided in said circumferential wall for introducing an airflow into said annular gap;
a regeneration system for regenerating said filter blocks of said rotary separating unit by a regenerating stream passing through said filter blocks in said radial direction to remove impurities received in said filter blocks; and
a cooling system for directing a cooling airflow through said filter blocks in said radial direction, said cooling system being arranged between said regeneration system and said airflow inlet in a rotational direction,
wherein said airflow inlet and said regeneration system are both positioned in the same circumferential sector of maximum 180 degrees.
