Ma mua o nā makahiki 1930, ʻo Kelemania a me Farani wale nō ka mea hiki ke hana i nā mea hoʻoheheʻe oxygen.I kēlā manawa, hiki i nā mea hana oxygen (variable pressure adsorption oxygen generators) ke hoʻokō wale i nā pono o ka wili a me ka ʻoki ʻana i ka oxygen a me nā mea hana nitrogen e pono ai no ka ʻoihana kemika.ʻO ka hana ʻana o nā mea hana oxygen he mea liʻiliʻi a liʻiliʻi, me ka mana o 2m3/h a hiki i 600m3/h a ma kahi o 200 mau ʻano.ʻO kamea hoʻoheheʻe oxygenʻO ke kaʻina hana i hoʻohana ʻia he kaʻina hana kiʻekiʻe a me ke kaʻina hana.
Mai ka makahiki 1930 a hiki i ka makahiki 1950, ma waho aʻe o Kelemānia a me Palani, ua hoʻomaka pū nā ʻāina ʻē aʻe e like me ka Soviet Union, Iapana, ʻAmelika Hui Pū ʻIa a me United Kingdom e hana i nā mea hana oxygen.I loko o kēia manawa, me ka hoʻomohala ʻana o ka hana, ua hoʻonui ʻia ka māhele noi o nā mea hana oxygen (variable pressure adsorption oxygen generators) a ua hoʻonui ʻia ka hoʻomohala ʻana o nā mea hana oxygen nui.No ka mea, ʻoi aku ka kiʻekiʻe o ka uila a me nā mea metala e hana ai i ka 1 m3 o ka oxygen i nā mea hoʻoheheʻe oxygen nui ma mua o nā mea hoʻoheheʻe oxygen liʻiliʻi a me ka liʻiliʻi, ua hoʻonui nui ʻia nā ʻano o nā mea hana oxygen nui mai 1930 a 1950, e like me 5000 m3 / h i loko. Kelemānia Komohana, 3600 m3 / h ma USSR a me 3000 m3 / h ma Iapana.nā kaʻina hana i hoʻohana ʻia i kēlā manawa, ma waho aʻe o ke kiʻekiʻe a me ke kiʻekiʻe, hoʻomaka e hoʻohana i nā kaʻina hana kiʻekiʻe a haʻahaʻa.I ka makahiki 1932, ua hoʻohana ʻo Kelemania i nā mea hana oxygen no ka manawa mua i ka ʻoihana metallurgical a me ka amonia.
Ma hope o 1950, ma waho aʻe o ka oxygen generators (variable pressure adsorption oxygen generators) i hana ʻia ma nā ʻāina i luna, aia ʻo Kina, Czech Republic, East Germany, Hungary, Italia, etc. ).
Ma muli o ka hoʻomohala ʻana o ka ʻoihana kila, ka ʻoihana mea kanu nitrogen a me ka ʻenehana rocket, ua piʻi wikiwiki ka hoʻohana ʻana i ka oxygen a me ka nitrogen, ka mea i hāpai i ka hoʻomohala nui o nā mea hana oxygen.Mai 1957, 10,000m3 / h oxygen generators ua hoʻolauna ʻia kekahi ma hope o kekahi.mai ka makahiki 1967, e like me ka helu helu ʻole, aia he 87 mea hoʻoheheʻe oxygen nui ma luna o 20,000 m3 / h, ʻo ka ʻāpana nui he 50,000 m3 / h, a ke kūkulu ʻia nei ka ʻāpana nui.
I nā makahiki he 20 i hala iho nei, ua piʻi wikiwiki ka laulā huahana a ua hoʻokumu mālie i kahi moʻo.No ka laʻana, West Germany Linde's nui oxygen generator he 1000 ~ 40000m3 / h typical huahana;Ua loaʻa iā Japan kobelco OF moʻo;Hana ʻo Japan Hitachi i nā hiʻohiʻona TO a pau;He ʻano NR ko Iapana Oxygen;Loaʻa iā Britain he 50 ~ 1500 tons / lā huahana huahana.I ka manawa like, hoʻohana maoli nā mea hana oxygen nui i ke kaʻina hana haʻahaʻa haʻahaʻa.
I ka pōkole, ʻo ka hoʻomohala ʻana o ka oxygen generator (variable pressure adsorption oxygen generator) he hana kūpono ʻole, a ua hoʻomohala nā mea hana mai ka liʻiliʻi a me ka nui.Ua hoʻomohala ʻia ke kaʻina hana mai ke kiʻekiʻe kiʻekiʻe (200 atmospheres), medium pressure (50 atmospheres) a me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa i ka piha haʻahaʻa haʻahaʻa (6 atmospheres), no laila e hōʻemi ana i ka hoʻohana ʻana i ka mana a me ka hoʻohana ʻana i nā mea metala o ka mea hana oxygen a hoʻonui i ka hana. pōʻaiapuni.
