<p><P>PROBLEM TO BE SOLVED: To provide a dehumidification apparatus that can reduce a running cost by decreasing loss of a compressed gas. <P>SOLUTION: A large number of hollow-fiber membranes 13 made of polymer osmosis membrane are bundled in a housing 12. The inside of the hollow-fiber membrane 13 in the housing 12 is a high-pressure zone S1 and the vicinity of the outside surface of the hollow-fiber membrane 13 is a low-pressure zone S2. Dry air less humid than compressed air before dehumidification to be charged to the high-pressure zone S1, is introduced into the low-pressure zone S2. The dry air is introduced via a route A2 for supplying dry air which is another route than a route A1 for the compressed air to be dehumidified during passing through the hollow-fiber membrane 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
