<p>In a method for regeneration of moist powder adsorption agent, the moist-charged adsorption agent is first fed into the lower area of a fluidized bed which is provided with an aeration and heat-carrying material; the agent then is fed upwardly through the heat-carrying material while being simultaneously dried, and then the agent is withdrawn together with the vortex gas from the fluidized bed. The agent is separated from the vortex gas in a successively switched separator, and is then fed to a further fluidized bed which is provided with a further aeration and heat-carrying material. The agent is fed in that further bed upwardly through the further heat-carrying material and is simultaneously regenerated. The agent is then discharged together with the further vortex gas from the further fluidized bed. The vortex gases which are withdrawn can be reused as mixing gases during the vortex gas generation. The adsorption agent can be mixed with a sludge, for example, from a sewage treatment plant, which, if necessary, is gasified together with the substances of the adsorption agents in the regeneration step.</p> |
