umsebenzi wokuhlanganisa uVPSA wesintsha kwezindaba
I VPSA (Vacuum Pressure Swing Adsorption) yilizwe le-oksijeni elibonisa uphawu oluncane lokuhlola ukusebenza kwe-oksijeni ngokulandelayo, ukuhlanganiswa nokuthi kuhlola imigca esisekelwe ngaphandle kwezinhlobo zokusebenzela. Leli phawu oluncane lusetshenziswa amasieve amabomolekulari aqinisekisi ukususa i-oksijeni kwi-nyawo yenkululeko ngephawu engenziwe ngokupheleleyo. Umthetho wakhiwo wenze ukusebenza ngokushesha kunye nokuhlola kabusha, ukuba kuhlinyiswe umsebenzi wesiphumo sokudla kwe-oksijeni ngendlela efanelekileyo nokuhlola okungcono kweenergy. Isistimu sakuxhasa sokubheka sikhishwa ukukhathalela ukusebenza nokuhlola isivumelwano sesihlanu se-oksijeni esingavumelekile kakhulu phakathi kwe-90% kunye ne-95%. Ngenxa yokuba izindlela zakusebenzela zikwahlula phakathi kokufakelwa ezincinci kunye nokufakelwa kwezindaba eziphakamile, izilizwe ze-oksijeni ze-VPSA zingabhamuka phakathi kwe-50 kunye ne-15,000 Nm³/hr ye-oksijeni. Ukusetha kwesiphumo lesi sicacile ukusetyenziswa nokugcina, futhi ukusebenza kweautomation akukho into omnikhangelwe ukusebenza. Izilizwe zakuxhasa zisebenzela izindlela eziningi, phakathi kokubhala amagceke, ukuhlola amaglass, ukususa amaxhobo wezinyoni, kunye nokuhlola izindawo zokusebenzela izinyathelo zesihlobo somedi, uzokusiza okuningi lokunxibelela kweziqhutywa ezintathu zokulima i-oksijeni.
