Abstract:
1. A dry air supplying apparatus, comprising: two rotors respectively supported by support frames, each of the rotors having a component member carrying an absorbent; partitioning members respectively supported by the support frames, each of the partitioning members defining at least an absorbing zone and a recovery zone in the rotor corresponding to the partitioning member, depending on an angular positional relationship between the rotor and the corresponding partitioning member, wherein, in the absorbing zone, moisture and organic matters are removed from air passing therethrough by the absorbent in the absorbing zone, and in the recovery zone, the absorbent deteriorated due to absorption of the moisture and the organic matters is recovered; a common drive means for driving both the rotors for rotation, the common drive means including a single motor and driving force transmitting members that transmit driving force generated by the single motor to the two rotors to drive the rotors for rotation, respectively; a circulation passage that guides air sucked from a target space so as to sequentially pass through the absorbing zones of the rotors for removing moisture and organic matters from the air, and thereafter return to the target space; and an exhaust passage, provided with heating means, that guides a part of the air having passed through the absorbing zones of the rotors so as to pass through the heating means, and thereafter pass through the recovery zones of the rotors for desorbing the moisture and the organic matters from the absorbents of the rotors.
