<p>Exhaust gas (G) containing fine particles and noxious/smelly gas is mixed with powdered absorbents in gas pipelines (9A, 9B) so that the fine particles and noxious/smelly gas are stuck and adsorbed to the powdered adsorbents, and the resulting admixture is then caused to pass through dust collectors (14A, 15A) so that the powdered adsorbents and cleaned exhaust gas are separated. The noxious/smelly gas adsorbed to the powdered adsorbents is desorbed by heating the powdered adsorbents so separated through contact with hot air flow or heating the same indirectly in a pipeline (12B). The fine particles stuck to the powdered adsorbents are pyrolyzed by heating a part or the whole of the powdered adsorbents so desorbed through contact with hotter air flow or heating the same indirectly in a pipeline (12C). The powdered adsorbents regenerated in this way are sent back to the gas pipeline (9B) through a pipeline (12E) so as to be mixed with exhaust gas (G) for re-use.</p> |
