<p>PROBLEM TO BE SOLVED: To provide a gas dehumidifying device in which an adsorbent can be restrained from wearing even when the adsorbent is used over a long period of time, the adsorption capacity can be enhanced, the reliability can be enhanced by prolonging service life of the adsorbent and the workability can be enhanced by exchanging the old adsorbent with new one more easily. SOLUTION: This gas dehumidifying device is provided with a pair of 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. Each adsorption column is provided with an air-permeable end ring 42 arranged on the opened end of the adsorption column, an air-permeable intermediate ring 43 which holds the adsorbent in the adsorption column and is housed to be freely movable in the axial direction and a spring member 44 which is interposed between the ring 42 and the ring 43 and elastically pressurizes/presses the ring 43 to the adsorbent.</p> |
