Abstract:
Combustion fumes charged with dust and gaseous pollutants are purified during upward flow through a bed of solids with absorptive and/or catalytic effect, with the bed renewed at intervals by adding fresh solids from above. - During periods of withdrawal of used solids from the reaction chamber base and of application of fresh solids, the flow of fumes is interrupted. The reaction column is pref. divided into a number of laterally adjacent chambers functioning in parallel and while fume flow through a given chamber has stopped, the ascending fumes are deflected into one or more lateral chambers. - The cleaning process, which pref. follows a wet washing stage is controlled by a slider or valved and spanning the column floor and operating at fixed time intervals to open or close fume access.
