<p>PURPOSE:To provide an adsorption device by which the replenishment and replacement of a pellet absorbent in accordance with the fluidization and pulverization are facilitated. CONSTITUTION:There are a packed bed of a pellet dehumidifying agent 3 and a packet bed of a pellet nitrogen absorbent 5 in an absorber 1. A level detector is installed above each packed bed. When the level of the packed bed is lowered by the fluidization and pulverization of the pellet absorbent in each packed bed, the level detector detects it to operate a vacuum pump 42, causing each pellet absorbent to be replenished from a dehumidifying housing can 50 or an absorbent housing can 41 to each packed bed. When the adsorbent is withdrawn from each packed layer, a vacuum pump 42 is used to take out the absorbent from nozzles 33, 34 in the lower part of each packed bed.</p> |
