<p>PROBLEM TO BE SOLVED: To provide a gas dehumidifying device enhanced in adsorption capacity and reliability and prolonged in service life of an adsorbent by arranging a port for introducing gas into each adsorption column at the position apart from the central part of the adsorption column and introducing the gas into each adsorption column in a uniformly diffused state allow the adsorbent in the adsorption column to act uniformly. SOLUTION: This gas dehumidifying device is provided with two adsorption columns 3, 4 packed with the adsorbent 17 so that one adsorption column is used for dehumidifying gas and a part of the dehumidified gas is introduced into the other adsorption column to regenerate the adsorbent packed there. The gas dehumidifying device is provided with an inlet head 15 which has a recessed part 15a to be fit to the ends of the adsorption columns and supports the adsorption columns, gas introducing ports 31, 32 opened on the outer peripheral surface of the part 15a to introduce/guide the gas into the adsorption columns and flow rectifying plates 60 each of which is fit to the part 15a and has a perforated part 62 for diffusing/rectifying the gas introduced/guided from the port 31 or 32 toward the inside of the adsorption column.</p> |
