12 The invention relates to a process and an apparatus for the adsorption or chemisorption of gaseous materials from a raw gas stream. The raw gas mixed with the adsorbent is led to a cloth filter in the centre of which is a trap tube and dust-guiding plates located laterally and under the trap tube. The raw gas is injected by a nozzle from below into the trap tube. Gas and separated dust recirculates around the trap tube. This creates an internal dust-gas-recirculation around the trap tube. Moisture can be added to the raw gas and/or the adsorbent and/or the mixture of both, the moisture preferably being steam. |
