Abstract

An apparatus for thermal regeneration of loaded adsorbents by a hot solid heat carrier consisting of a container having a head and a base. The head holds feed pipes for the adsorbent and the heat carriers and the base has a discharge unit. A bottom arrangement of pipes is located underneath these feed pipes. A gas feed duct is located outside this container and connected to the bottom arrangement of pipes which has gas outlet nozzles. The pipes in this bottom arrangement of pipes are spaced apart by a multiple of the grain diameter of the absorbents and the heat carrier. The gas outlet nozzles may be directed downwardly. Outlet connections for desorption gas in the head may lead to the gas feed duct. The bottom arrangement of pipes may be located in the upper portion of the container and a filling level meter may be electrically connected through a regulating circuit to the discharge unit above the bottom arrangement of pipes. The feed pipe for the adsorbent may protrude into the layer above the bottom arrangement of pipes. A dust separator may be located in the head in front of the opening of the outlet connection for the desorption gas.
