PROBLEM TO BE SOLVED: To provide a deodorization device the running cost of which is restrained from being raised by keeping the treating capacity of an adsorption rotor or a catalyst. SOLUTION: This deodorization device 10 for deodorizing the gas to be treated, is provided with the adsorption rotor 20, a catalyst treating part 36, the first and second heating parts 33, 35, an air blowing part 31 and a switchover part 19. In the rotor 20 and the part 36 the gas can be treated at two high and low temperatures. The parts 33, 35 and the part 31 are used when the rotor 20 and the part 36 are heated to the first temperature or the second temperature higher than the first temperature. The part 19 is used for switching over the temperature to be heated by the parts 33, 35 and the part 31 to any of the first and second temperatures so that any of the first gas treatment at the first temperature and the second gas treatment at the second temperature is carried out. |
