本发明工作过程如下：
本发明装置启动前，系统阀门均处于关闭状态。启动空气压缩机1，外界空气被压缩，然后打开第一进口截止阀4、第二进口截止阀5、第一出口截止阀8、第二出口截止阀9、第三进口截止阀15、第四进口截止阀16、第五进口截止阀18、蒸发器进口截止阀24、液体截止阀32、副换热器进口截止阀33、第三低压塔进口截止阀35、第一低压塔进口截止阀36、第二低压塔进口截止阀37、低压塔排液截止阀62、排空截止阀63、工艺截止阀64，系统管道吹扫2-3小时，然后关闭第二进口截止阀5、第一出口截止阀8、第三进口截止阀15、第四进口截止阀16、蒸发器进口截止阀24、副换热器进口截止阀33、第一低压塔进口截止阀36、第二低压塔进口截止阀37、氧气增压机进口截止阀59、低压塔排液截止阀62、排空截止阀63、工艺截止阀64。
向低压塔28顶部缓慢输入辅助冷源，进入低压塔28的压缩空气开始液化，等到低压塔28底部积液到规定液位后，打开第三进口截止阀15、蒸发器进口截止阀24，启动增氧空气压缩机21，经过增氧塔17后富氧高压空气通过主换热器22进入低压塔底部蒸发器27，在低压塔底部蒸发器27中冷凝成液体，然后通过副换热器38，打开第一低压塔进口截止阀36，减压后富氧高压液态空气进入低压塔28上部。
维持低压塔28精馏过程18～24h，然后缓慢打开排空截止阀63，主换热器22和副换热器38开始快速冷却。排空截止阀63打开2～4h后，缓慢打开工艺截止阀64，低压塔内不纯物料开始排放。随着高压塔29温度逐步降低，高压塔29内温度、压力开始逐步向设计值逼近，高压塔29内精馏过程开始逐步建立，高压塔29内气体液化释放热量提供给低压塔28内气体蒸发。高压塔29底部液体蒸发热源为主换热器22热端出口50增压富氧空气。
高压塔29精馏过程进行8～12h，打开副换热器进口截止阀33，高压塔29顶部氮气进入低压塔中部冷凝蒸发器34冷凝侧，将高压塔29顶部氮气冷凝，产生的热量用于低压塔28中部下降液体的蒸发，以补充低压塔28内精馏蒸汽量。高压塔29顶部氮气冷凝后通过副换热器38，打开进第二低压塔进口截止阀37，高压塔29顶部冷凝氮气进入低压塔28上部。
在高压塔29精馏过程建立过程中，随着低压塔28冷量不断传递到高压塔29，高压塔29底部开始出现积液，并通过副换热器38进入高压塔29上部。
将LNG(液化天然气)通入主换热器第三冷端进口46，用来补充主换热器22所需冷量，主换热器第三冷端出口45汽化LNG可作为燃料电池23发电原料，所产生电能用来供给装置空气压缩机1、增氧空气压缩机21、氧气增压机60，降低了本发明装置对外界电能输入的依赖。
维持高压塔29和低压塔28精馏过程6～8h，等低压塔28底部氧气和高压塔29顶部氮气纯度达标后，可通过氧气增压机60输出氧气。
本发明装置配置有吸氧装置，用来接收增压低纯氧气。一般情况下，当低压塔28底部液氧纯度合格后，可打开液氧截止阀30，低压塔28底部液氧流入液氧储罐31。本发明装置内氧气便携呼吸装置⑤需要充装氧气时，有两种途径：
关闭工艺截止阀64，打开氧气增压机进口截止阀59，低压塔28底部氧气经过氧气增压机60增压后输入氧气便携呼吸装置中的氧气缓冲罐39中；或关闭工艺截止阀64、氧气增压机进口截止阀59，打开液氧输运截止阀61，低压塔28底部液氧复热气化后通过氧气增压机60增压后输入氧气便携呼吸装置中的氧气缓冲罐39。
本发明装置低压塔28顶部氮气进入副换热器38冷端进口55，冷却副换热器38热端进口52、53、54；然后副换热器38冷端出口51进主换热器22冷端进口47。
主换热器第一冷端出口43复温氮气流路依据工艺过程有三条：直接通过排空截止阀63直接排大气；作为增压塔解析置换用气；作为净化塔解析置换用气。
主换热器冷第一端出口43复温氮气用来增氧塔17解析时，关闭排空截止阀63，根据需要解析置换的增压塔，执行如下操作之一：1)关闭第四进口截止阀16，打开第二放空截止阀14，将需要置换的增压塔内空气排出至大气压；打开第一吹扫截止阀19，主换热器第一冷端出口43复温氮气进入需要置换的增压塔，进行解析操作3～5h。解析完成后关闭第一吹扫截止阀19和第二放空截止阀14，打开第四进口截止阀16，被解析增氧塔继续工作。2)关闭第三进口截止阀1615，打开第一放空截止阀13，将需要置换的增压塔内空气排出至大气压；打开第二吹扫截止阀20，主换热器冷端出口43复温氮气进入需要置换的增压塔，进行解析操作3～5h。解析完成后关闭第二吹扫截止阀20和第一放空截止阀13，打开增氧塔17第一进口截止阀15，被解析增氧塔继续工作。
低压塔28底部出氧量在设计范围内由主换热器第二热端出口50高压增氧空气调节；高压塔29顶部氮气进入低压塔中部冷凝蒸发器34的量主要用来调节低压塔28内总的上升蒸汽量。
低压塔28顶部辅助冷源用于设备启动阶段裸冷以及低压塔28底部积液；还用于设备稳定运行过程中用来补充因外部环境变化而导致的冷量损失。
高压塔29底部辅助电加热器25用来满足氧气产量增加时高压塔29上升蒸汽量的需求。当装置氧气生产量增加时，进入低压塔28的高压增氧空气量增加，相应进入高压塔29的压缩空气量减少，通过高压塔29底部辅助电加热器25满足高压塔29的上升蒸汽量要求。

当需要用氧时，需吸氧人员可在本发明装置旁现场吸氧；实现氧气便携呼吸装置现场氧气充装，随身携带，随时吸氧。
