  Conventionally, it is known that the adsorption capacity of the deodorizing unit decreases when the humidity of the processing gas (inflowing air) is high. Therefore, a dehumidifying means such as a dehumidifying rotor or a heat exchanger is provided on the downstream side of the dehumidifying means. Has disclosed a deodorizing apparatus in which a deodorizing unit including an adsorption filter and an ultraviolet lamp is arranged (see, for example, Patent Document 1).

However, since the deodorizing unit for decomposing odor components contained in the processing gas (inflowing air) is particularly configured to have an ultraviolet lamp, the structure becomes complicated and disadvantageous in terms of cost. Had.

By providing the deodorizing unit 3 having a decomposing portion to be decomposed and the blower fan 4, dust in the processing gas (inflowing air) sucked from the suction port 9 is captured by the dust removing filter 2, A very small odor component that cannot be captured by the dust removal filter 2 is adsorbed by the adsorbing portion of the deodorizing unit 3 so that the processing gas (inflowing air) that has been cleaned and adsorbed by the odor component is cleaned. The air outlet 10 is blown out into the air-conditioned room.

  The adsorbing part of the deodorizing unit 3 is made of, for example, ceramic or zeolite, and the decomposing part of the deodorizing unit 3 is made of, for example, metal particles supported on the adsorbing part. Since the processing gas (inflowing air) is dehumidified by cooling the unit 3, the odor component is more easily adsorbed, and the adsorbed odor component is less likely to jump out of the adsorbing portion, thereby adsorbing the odor component. On the other hand, during the discharge / decomposition operation, the process gas (inflowing air) and the deodorizing unit 3 are heated to increase the decomposition ability for decomposing odor components.
