Abstract
A fixed bed layer of a reactor column for the execution of anaerobic decosition processes, which column is divided by screen partitions into segments one above another with intermediate spaces for gas discharge from the column through discharge funnels into one or more corresponding, ascending pipes. Additional devices for the introduction of liquid or gas into the individual fixed bed segments produce turbulence and remove excess sludge from the fixed bed layer. Annular guide elements project from the inner wall of the column underneath the funnel and have a constricted cross section which defines an annular channel to the next column segment. Thus, a liquid stream is not blocked during optimal gas collection in the funnel. The funnels are preferably installed in the screen floor of the subsequent column segment.
