GAS SEPARATION DEVICE

摘要

A simple and low cost gas separation device is provided. The gas separation device (100) comprises: an adsorption tower (110) having an adsorption agent (120) that adsorbs oxygen in a prescribed pressure and temperature environment and having at least one section thereof exposed to a higher temperature atmosphere than normal temperature; a first supply path (132) connected to the adsorption tower and guiding into the adsorption tower air that has been blown from a blowing device (130); a second supply path (136) that guides air at a lower flow rate than the first supply path into the adsorption tower; a separated gas discharge path (140) connected to the adsorption tower and which discharges separated gas; a first heat exchange unit (150) that exchanges heat between the separated gas discharged from the adsorption tower and the air guided into the adsorption tower from the first supply path; an oxygen discharge unit (160) that reduces pressure inside the adsorption tower causes oxygen to be desorbed from the adsorption agent and discharges the oxygen from the adsorption tower; and a second heat exchange unit (170) that exchanges heat between the oxygen and the air guided into the adsorption tower from the second supply path.
