uprosesu wesithuthi somlomo weoxygen
Umkhondo wokusebenza kwezilondolozi zokuHamba Ngenqanawe (PSA - Pressure Swing Adsorption) yomphakathi weOksijini uyimvume lezinto ezintathu ngenxa yokusebenzisa umthetho omkhulu okugcina ukuze ithole iOksijini engcono ngokwesikhatsi esikhoyo esikhundleni. Lolu hlobo olunovuthango lokusebenza ngokusebenzisa amabedi amahhovu amasendle angaphakathi ukubheka isigaba sikaNitrophe nekufinyelela kuOksijini ukuya kwenye indawo. Ukuphela kwiseva sihlala nokuhlola iNtshonalanga komhlabathi, phakamisa ukuba akusuke kuhlola ngokukhuluma ngokwesikhatsi esikhundleni. Umthetho wesentlaleni PSA usetyenziswa ngeentsuku ezincane ezinikezela ukuba ibedi elithile lisebenzise ukucutshwayo kwezilondolozi ngelixa lethathu kulandelayo, futhi ibedi elibheneyo lisetshenziswa ukuba kuhle, uzame ukuthiwe kuhlukeleleyo kweOksijini. Isistemo sikwazi ukuthiwe imigquelo yeOksijini ephindwe njengemvelo 93-95%, ukuba kuhle lokhu kungasebenzi kakhulu ngazo zonke izindlela ezinhlanganekayo ezindaweni nezindawo zokudlwili. Umphakathi usebenzisa ngemiphumela eyahlukene, futhi amanye amazwi amadlule, ngokushesha, ukubheka, ukushesha, futhi ukuphuma, wonke amanye amazwi aqhunywe ngokusebenzisa amaxwebhu omncane wemikrosiphesa. Lolu hlobo lwemthetho loluhloniphe umculo wokugcina iOksijini ekuseni lokho kungafanele ukusetshenziswa ukuthiwe ukuswelwa kweOksijini emanzini kunye nokuthiwe ukusetyenziswa ngokuzidinga. Umlilo olandelayo ungene ngokusebenzisa umoya wendawo wesikhatsi kunye nomoya wesikhatsi wendawo ukuthola iOksijini, ukuba kuhle lokhu kungasebenzi kakhulu kunye nokuthi kuhlukeleleyo kanye nokuthi kuhlukeleleyo. Izimpahla zeOksijini zesentlaleni PSA zisebenzisa ngokubanzi kwindawo eziningi, ngokushesha kanye nokuthi kuhlukeleleyo, futhi kuhlukeleleyo, kwindawo ezinokuthiwe ngazo zezindawo ezindaweni zokuthola iOksijini.
