amamehlo aqokisekisa lokugcina amadlozi aVPSA
Imishini yokukhiqiza i-oksijini ye-VPSA (Vacum Pressure Swing Adsorption) iyisixazululo esiphambili sokukhiqiza i-oksijini endaweni. Lolu hlelo oluthuthukile lusebenza ngokusebenzisa izinto ezikhethekile zokuhlunga izinhlayiyana ukuze kuhlukaniswe umoya-mpilo nomoya ozungezile ngenqubo elawulwa kahle yokucindezela. Le mishini isebenzisa izitsha ezimbili eziyinhloko ezigcwele izinto zeolite, eziguquguqukayo phakathi kwezigaba zokumunca nokumunca ukuze kuqinisekiswe ukukhiqizwa komoya-mpilo okuqhubekayo. Isebenza ngaphansi kwengcindezi evame ukusuka ku-0.3 kuya ku-2.5 bar, izinhlelo ze-VPSA zingafinyelela emazingeni okuhlanzeka komoya-mpilo afinyelela kuma-95%. Lobu buchwepheshe buhlanganisa izinhlelo zokulawula eziyinkimbinkimbi eziqapha futhi zilungise amapharamitha okusebenza ngesikhathi sangempela, ziqinisekisa ukusebenza kahle nokusebenza kahle. Amadivayisi anamuhla e-VPSA anezinto ezonga amandla, kuhlanganise nama-compressor athuthukile namaphampu okuhlanza, okufaka isandla ekwehliseni izindleko zokusebenza. Imishini yakhelwe ukufaka imodeli engqondweni, evumela ukwanda okulula kwamandla okukhiqiza kusuka ku-50 kuya ku-20 000 Nm3/h womoya-mpilo. Lokhu kuguquguquka kwenza izinhlelo ze-VPSA zilungele izimboni ezihlukahlukene, kuhlanganise izikhungo zezempilo, izitshalo zokulungisa izinsimbi, izikhungo zokuhlanza amanzi angcolile, kanye nemisebenzi yokukhiqiza amakhemikhali. Ukusebenza okuzenzakalelayo kwalolu hlelo kudinga ukuqapha okuncane, kuyilapho izici zokuphepha ezakhelwe ngaphakathi nezinyathelo zokuqeda ukucindezeleka kuqinisekisa ukuphakelwa komoya-mpilo okuthembekile nokungaphazanyiswa.
