    • A simple and inexpensive gas separation device is provided. The gas separation device (100) includes: an adsorption tower (110) having an adsorbent (120) 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 (132) connected to the adsorption tower for guiding into the adsorption tower air that has been blown from a blower device (130); a second feed passage (136) for guiding air, at a lower flow rate than the first feed passage, into the adsorption tower; a separated gas discharge path (140) connected to the adsorption tower for discharging a separated gas; a first heat exchanging unit (150) 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 (160) 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 (170) for exchanging heat between oxygen and the air guided into the adsorption tower from the second feed passage.
    • 提供了一种简单而廉价的气体分离装置。 气体分离装置(100)包括:具有在规定的压力和温度环境中吸附氧气的吸附剂(120)的吸附塔(110),其中至少一个部分暴露于比正常温度更高的温度气氛; 连接到吸附塔的第一进料通道(132),用于引导已经从鼓风装置(130)吹出的吸附塔空气; 用于以比第一进料通道更低的流速将空气引导到吸附塔中的第二进料通道(136) 分离的气体排放路径(140),其连接到用于排出分离的气体的吸附塔; 第一热交换单元(150),用于在从所述吸附塔排出的分离气体与从所述第一供给通道引导到所述吸附塔中的空气之间进行热交换; 用于降低吸附塔内部的压力的氧气排出单元(160),使氧从吸附剂解吸,并从吸附塔排出氧气; 以及第二热交换单元(170),用于在从第二进料通道引导到吸附塔中的氧气和空气之间进行热交换。
