isistimu sokuhluka amadlozi angaphezulu kwe-PSA
Umkhondo wokuhlanganisa i-O2 we-PSA uhamba ngokushesha lokulandelayo kwiqhutywa lembaluleneyo yokuhlola ukuhlawulwa kokuba kwezilungiselelo ezinhlanganekayo, kunyuselwe ukufinyelela izintathu zasekhaya nge-Pressure Swing Adsorption ukusetshenziswa ukubuyiselwa kwezintathu eziqondisiwe kumoya omnyama. Lomkhondo olunyeleyo ungene ngokusebenzela amasiko amahluke asebenza amafinga lomolekule olandelayo okuyityiswa ukubuyisela umoya omncane ngakwabo nokuvamukela umoya omkhulu ukuya kuqhutywa, ukuhlawulwa kwimbali yezilungiselelo ezihlinzekileyo. Umkhondo ungena ngemibuzo eminingi eyahlukanisiwe, phakathi kwe-amaphutha lamoya, amaxwebhu amaphambili, amatoura amabuyiselwa, kunye nezixhobo zokudibanisa, zikuphucwayo ukuba zikhona umboniso omncane wezilungiselelo ye-oxygen. Ukusebenza kwe-PSA O2 Generation System ungene ngokuphelele kwezindawo ezininzi ezidinga umoya omncane ngokuphihlwe, ungene ngokuphakamisayo kunye nefakazi eliphakeme. Iindlela leyi-phutha lihlola imigca yezilungiselelo ye-oxygen esiqinile kakhulu, ngokusho ukuba kungenani kwe-90% kunye ne-95%, lokunesiphiwo sokuthi sifanele kwezindawo zokugcina, amaqhutywa amaphambili kunye nezindlela zokusebenza. Ukusebenza kwemkhondo wenze ukuba kuhlobene nangokuqinisekiswa kweziBantu, ngokuba kuhlala kuhluke nokuhlola imigca yesilungiselelo ye-oxygen. Amaphutha amodern ya-PSA akhetha amandla amacabango ekuphakamisayo, ungene ngokusebenzela ukufinyelela kwezithelo zombuso kwezilungiselelo, imigca yezilungiselelo kunye nezixhobo zokudibanisa. Leli dolo lengezantsi lenze ukuba alisho inqanawe yokuthi kufanele kube noma yilungiselelo lokuhlula kwezilungiselelo, ungene ngokusebenzela ukuba kuhloniphe umntu ngokuphela ukwenza imigca yesilungiselelo ye-oxygen. Ukusetshenziswa kwe-PSA usetyenziswa ngokubuyekeza ukuba kuhlanganisiwe kwezilungiselelo ukusuka kwezindawo ezivavanye, kunye nokuthi amaphetho amabhedwayo akhetha ukuba kuhloniphe umoya omncane.
