Ngaphambi kweminyaka yawo-1930, iJalimane neFrance kuphela ababekwazi ukukhiqiza amajeneretha omoya-mpilo.Ngaleso sikhathi, amajeneretha omoya-mpilo (i-variable pressure adsorption oxygen generator) ayekwazi ukuhlangabezana nezidingo zokushisela nokusika imishini yokukhiqiza umoya-mpilo ne-nitrogen edingekayo embonini yamakhemikhali.Ukukhiqizwa kwamajeneretha e-oksijini ngokuyinhloko kwakuncane futhi kunobukhulu obuphakathi, amandla angu-2m3/h kuya ku-600m3/h kanye nezinhlobo ezingaba ngu-200.Ii-oxygen generatorInqubo esetshenzisiwe iyinqubo yokucindezela okuphezulu kanye ne-medium-pressure.
Kusukela ngo-1930 kuya ku-1950, ngaphezu kweJalimane neFrance, amanye amazwe anjengeSoviet Union, Japan, United States ne-United Kingdom nawo aqala ukukhiqiza amajeneretha omoya-mpilo.Ngalesi sikhathi, ngokuthuthukiswa kokukhiqizwa, insimu yokusetshenziswa kwamajeneretha oksijini (i-variable pressure adsorption oxygen generator) yandiswa futhi kwathuthukiswa ukuthuthukiswa kwamajeneretha amakhulu oksijini.Njengoba ugesi kanye nezinto zensimbi ezidingekayo ukuze kukhiqizwe i-1 m3 ye-oksijeni kumajeneretha amakhulu e-oksijeni kwakuphakeme kunama-generator ama-oksijeni amancane naphakathi nendawo, izinhlobonhlobo zamajeneretha amakhulu oksijini zanda kakhulu kusukela ngo-1930 kuya ku-1950, njenge-5000 m3 / h I-West Germany, 3600 m3/h e-USSR kanye ne-3000 m3/h e-Japan.izinqubo ezisetshenziswa ngaleso sikhathi, ngaphezu kokucindezela okuphezulu nokuphakathi, zaqala ukusebenzisa izinqubo zokucindezela okuphezulu nokuphansi.Ngo-1932, iJalimane yasebenzisa amajeneretha omoya-mpilo okokuqala ngqa ezimbonini ze-metallurgical kanye ne-ammonia.
Ngemuva kuka-1950, ngaphezu kwamajeneretha omoya-mpilo (i-variable pressure adsorption oxygen generator) akhiqizwa kula mazwe angenhla, kukhona iShayina, iCzech Republic, i-East Germany, iHungary, i-Italy, njll. (I-China ingumthuthukisi ongasekho, wonke apholile ).
Ngenxa yokuthuthukiswa kwemboni yensimbi, imboni ye-nitrogen fertilizer kanye nobuchwepheshe be-rocket, ukusetshenziswa kwe-oksijeni ne-nitrogen kuye kwanda ngokushesha, okuye kwakhuthaza ukuthuthukiswa okukhulu kwamajeneretha oksijini.Kusukela ngo-1957, amajeneretha omoya-mpilo angu-10,000m3/h angeniswe ngokulandelana.kusukela ngo-1967, ngokwezibalo ezingaphelele, kunamajeneretha amakhulu we-oksijeni angu-87 ngaphezu kwe-20,000 m3 / h, iyunithi enkulu i-50,000 m3 / h, kanti iyunithi enkulu ingaphansi kokuthuthukiswa.
Eminyakeni engu-20 edlule, uhla lomkhiqizo landa ngokushesha futhi kancane kancane lwakha uchungechunge.Isibonelo, ijeneretha enkulu ye-oxygen ka-Linde yase-West Germany inemikhiqizo ejwayelekile engu-1000 ~ 40000m3 / h;Japan kobelco has OF uchungechunge;I-Japan Hitachi ikhiqiza wonke amamodeli we-TO;I-Japan Oxygen inohlobo lwe-NR;IBrithani inemikhiqizo yochungechunge lwamathani angama-50 ~ 1500 / ngosuku.Ngesikhathi esifanayo, amajeneretha amakhulu e-oxygen ngokuyisisekelo asebenzisa inqubo egcwele yokucindezela okuphansi.
Ngamafuphi, ukuthuthukiswa kwe-oxygen generator (i-variable pressure adsorption oxygen generator) kuyinkqubo engaphelele, futhi imishini iye yathuthukiswa kusukela ezincane naphakathi kuya ezinkulu.Inqubo ithuthukiswe kusuka kumfutho ophezulu (ama-atmospheres angu-200), ukucindezela okuphakathi (ama-atmospheres angu-50) kanye nokucindezela okuphezulu nokuphansi kuya ekucindezelweni okuphansi okugcwele (ama-atmospheres angu-6), ngaleyo ndlela kunciphisa ukusetshenziswa kwamandla kweyunithi kanye nokusetshenziswa kwensimbi ye-oxygen generator nokwelula ukusebenza. umjikelezo.
