vpsa umhlabathi weoxygen wesikhathini
Umkhuthazi wokuxhasa olunzima kakhulu weVPSA lweoxyjeni ulungisa umthetho wesintu esisodwa kakhulu kwisebentleli sokuxhasa amagasi. Isistimu esikhoyo lokhu siphumelela ukusetyenziswa komkhuthazo weVacuum Pressure Swing Adsorption ukuze sitshame amaxhasa elinamandla okuhlukekwini kusasendle ngokushesha. Isistimu sisisebenza ngephrozesi engaphakathi yokumkhangela emfuthe, apho iimolecular sieves ezikhoyo zicabangela izinkululo ze-nitrogen ngokuphi ndawonye ngalokhu ukuvumela loxyjeni ukubaleka. Ukusebenza kunikezela ngemipresshoni phakathi kwe-0.7 kunye ne-1.2 bar, umkhuthazi wahamba ukufinyelela imigomo ye-oxyjeni phakathi kwe-95%. Umkhuthazi wenquma iingxenye ezinhloko ezihlabeleka ezifumanekayo ezindabeni zokuba nokuhlola kanye nokugcina amaparamitha, uzokusure yezilungiselelo nokulula nokulula kuhhweba. Ukusetha kwabo kuhlanganisa ukukhetha nokususa, futhi ubungakanani bokusebenza kunesimo esikhoyo sokubaleka amaphandle, ngokusho ukuthi lokho kuhlanganisa ukusebenza kakhulu kanye nokulula kokulula kuhhweba ngokusebenzisa amaxesha enjalo. Amacala angaphambili angenziwe ngokwesimo esikhoyo sokubaleka umoya, umsebenzi wokuhlawula iphresshon, kunye nokusebenza ngokuzenzakalelayo okungavulumelwa ukusetyenziswa komoya ngokushesha ngenxa yalokho ukufinyelela umoya woxyjeni. Izindlela zokusetshenziswa zizihlanganisiwe ngamaxesha, ngokusho ukuthi abahlinzekile babeyenza umoya ngokushesha kusasa, ukusuka ukuthi kube kudingo lwesikhephe sezityenziswa lokusetyenziswa komoya lokulula nokuthi kube kudingo lwesikhephe lokusetyenziswa komoya olungabafundiswa kunye nokuthi kube kudingo lwesikhephe olungempumelelo lokusetyenziswa komoya ngokujwayelekile.
