<p>PURPOSE:To carry out the low dew point dehumidification even for the gas of high humidity by constituting the dry-type dehumidifying member of honeycomb structure with such a double structure that the area of introducing side of the gas to be dried is formed with silica gel as the main component and the area of discharging side is formed with zeolite as the main component. CONSTITUTION:The area 13 of introducing side of the gas to be dried of the dry-type dehumidifying member 10 of honeycomb structure is formed with >=85wt.% silica gel, and the area 14 of discharge side is formed with >=70wt.% zeolite. The gas 11 to be dried is flowed through continuous holes of honeycomb structure of a dry-type dehumidifying rotor consisting of these dehumidifying member 10. The gas to dried is firstly dehumidified in the area 13 consisting of the main component of silica gel which has a high dehumidifying capacity for a high humidity gas, and then, after dehumidified to low humidity, dehumidified in the area 14 consisting of the main component of zeolite which has a high dehumidifying capacity for a low humidity gas. Consequently, the dehumidified gas 12 becomes a low dew point gas.</p> |
