Abstract
Abstract A dehumidified air generator (10) has a plurality of rotatable absorption columns (12, 14, 16) filled with adsorbents for generating dehumidified air which will be used to dry a plastic material or the like. A directional control valve for switching between adsorbing and regenerating steps in the adsorption columns comprises a slide valve mechanism composed of a stator (34, 38) and a rotor (32, 36) slidably held against the stator. The rotor has a plurality of openings defined therein and communicating with inlet/outlet ports defined in side walls of the adsorption columns through tubes (40, 42, 44). By rotating the rotor in synchronism with the adsorption columns, the adsorbing and regenerating steps are switched to dehumidify, with the adsorbents, humid air introduced into the adsorption columns through the directional control valve and also to desorb the adsorbents for regenerating them.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A dehumidified gas generator comprising: a plurality of simultaneously rotatable adsorption columns having respective adsorbent beds housed therein; a rotor rotatable in synchronism with said adsorption columns; a stator fixedly disposed in confronting relation to said rotor; said rotor and said stator jointly serving as a directional control valve for switching between adsorbing and regenerating steps in each of said adsorption columns; adsorbing means composed of said adsorption columns combined together, said adsorbing means having a cylindrical shape divided into a plurality of chambers housing adsorbents of said adsorbent beds; rotating means for coupling said adsorption columns in the cylindrical shape to each other and rotating the adsorption columns in synchronism with said rotor; tubes having ends communicating with inlet/outlet ports defined in outer walls of said adsorbing means for passing a gas to be dehumidified through the adsorbent beds each having a predetermined thickness, from one surface to the opposite surface of each of the adsorbent beds; said rotor having a plurality of openings defined therein and connected to opposite ends of said tubes; and the arrangement being such that the adsorbing and regenerating steps in said adsorption columns can be switched by angularly displacing said rotor and said stator with respect to each other with said rotating means.
