<p>PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning method low in maintenance cost and running cost and high in performance, and to provide the device therefor. SOLUTION: An adsorption layer is filled in a revolving rotor 1. The gas 10 to be treated containing harmful substance is brought into contact with the absorption layer of a cleaning region 2 to absorb the harmful substance. The adsorption layer whose absorption performance is deteriorated due to the absorption operation is moved to a preliminary heating region 3 by rotating the rotor, is preheated with preheating gas 15, then is moved to a reproduction region 4 by rotating the rotor and is heated with desorbed gas 17 to desorb harmful substance from the absorption layer. The reproduced absorption layer is moved to a cooling region 5 by rotating the rotor, is cooled with cooling gas 21, and then is moved to the purifying region 2 by rotating the rotor to purify the exhaust gas.</p> |
