ABSTRACT In the invention, powdery adsorbent is mixed with an exhaust gas (G) including fine particles and a poisonous/nasty smell gas in gas pipelines (9A, 9B), thereby the adherence of the fine particles to powdery adsorbent and the adsorption of nasty smell gas with the powdery adsorbent are performed. The powdery adsorbent with the fine particles and poisonous/nasty smell gas is fed to dust collectors (14A, 15A), where the exhaust gas is separated from the powdery adsorbent and is purified. The separated powdery adsorbent comes in contact with hot blast at high temperature, or is indirectly heated in a pipeline (12B), thereby the adsorbed poisonous/nasty smell gas is desorbed by heating treatment. Further, a part of or all of the desorbed powdery adsorbent comes in contact with hot blast at higher temperature than the above mentioned temperature, or is indirectly heated in a pipeline (12C), thereby the fine particles adhered to the powdery adsorbent are thermally decomposed by heating treatment. In this way, the powdery adsorbent are regenerated, is returned to the gas pipeline (9B) through a pipeline (12E) and is mixed with the exhaust gas (G)in order to be reused.
