Abstract
A simple and inexpensive gas separation device is provided. The gas separation device () includes: an adsorption tower () having an adsorbent () that adsorbs oxygen in a prescribed pressure and temperature environment, with at least one section thereof being exposed to a higher temperature atmosphere than a normal temperature; a first feed passage () connected to the adsorption tower for guiding into the adsorption tower air that has been blown from a blower device (); a second feed passage () for guiding air, at a lower flow rate than the first feed passage, into the adsorption tower; a separated gas discharge path () connected to the adsorption tower for discharging a separated gas; a first heat exchanging unit () for exchanging heat between the separated gas discharged from the adsorption tower and the air guided into the adsorption tower from the first feed passage; an oxygen discharge unit () for reducing a pressure inside the adsorption tower, causing oxygen to desorb from the adsorption agent, and discharging oxygen from the adsorption tower; and a second heat exchanging unit () for exchanging heat between oxygen and the air guided into the adsorption tower from the second feed passage.
