The gas separation device includes an adsorption tower having at least one part thereof exposed to an atmosphere at a higher or lower temperature than normal temperature, a mixed gas feed unit, an adsorbent provided inside the adsorption tower to adsorb a matter contained in a mixed gas upon contact with the mixed gas in a prescribed pressure and temperature environment, and separate the matter from the mixed gas, a separated gas discharge unit that discharges a separated gas from the adsorption tower, and an adsorbed gas discharge unit that discharges from the adsorption tower the adsorbed gas which is adsorbed by the adsorbent. Heat reserving elements are arranged in the adsorption tower at positions upstream and downstream of the adsorbent in the mixed gas supply direction respectively such that the mixed gas, separated gas, and adsorbed gas flow through the heat reserving elements.

Gas separation device and gas separation method

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.
