Abstract
The invention relates to an apparatus for the regeneration of active carbon comprising particularly: PA1 a hopper for introducing the active carbon; PA1 a reactor (7) delimited by an elongated shaped sheath; PA1 a continuous Archimedes screw (10) situated inside the reactor to transport the active carbon to be regenerated; PA1 structure for heating by resistances (8), arranged inside the sheath of the reactor; PA1 structure situated above the unload end of the reactor (19) and in communication with the reactor, particularly for removing the gases; PA1 a coffer into which the Arichmedes screw unloads; PA1 structure for communication with the reactor and situated on the one hand close to the input of the reactor and on the other hand along the reactor to regulate the pressure inside the reactor and to inject steam. This apparatus for regenerating active carbon enables the powder active carbon to be regenerated efficiently.
