Regenerative separating device for separating impurities from an airflow

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;
• and
• 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, said regeneration system comprises a regeneration stream outlet for discharging said regeneration stream having passed through said filter blocks;
• and
• said regeneration stream outlet is divided into two sections, in said circumferential direction, for discharging a first partial regeneration stream and a second partial regeneration stream,
• wherein said airflow inlet and said regeneration system are both positioned in the same circumferential sector of maximum 180 degrees.
