umsebenzi wokuhlanganisa amafomu ephandleleni kweoxygen
Uhlelo lwe-PSA (Pressure Swing Adsorption) lwezimboni lokukhiqiza umoya-mpilo luyisisombululo esiphambili sokukhiqiza umoya-mpilo ohlanzekile endaweni. Lobu buchwepheshe obuphambili busebenza ngokusebenzisa izihlungi ezikhethekile zezinhlayiyana ukuze kuhlukaniswe umoya-mpilo namanye amagesi asemkhathini, ikakhulukazi i-nitrogen ne-carbon dioxide. Lolu hlelo lusebenza ngenqubo yomjikelezo lapho umoya onengcindezi udlula khona emibhedeni ye-zeolite adsorbent, ethatha i-nitrogen ngokukhetha ngenkathi ivumela umoya-mpilo ukuba udlule. Le nqubo ihilela izigaba eziningi ezihlanganisa ukucindezelwa, ukufakwa umoya, ukucindezelwa nokuhlanzwa, konke okulawulwa ngokucophelela ukuze kuqinisekiswe ukuthi umoya-mpilo awupheli. Izinhlelo zanamuhla ze-PSA zingafinyelela emazingeni okuhlanzeka komoya-mpilo afinyelela kuma-95%, okwenza zibe ezikahle kakhulu ekusetshenzisweni kwezimboni ezihlukahlukene. Ukusebenza okuzenzakalelayo kwalolu hlelo kuqinisekisa ukuthi abantu abahileleki kakhulu kuyilapho kugcinwa ukukhiqizwa komoya-mpilo njalo 24/7. Izakhi ezibalulekile zihlanganisa ama-air compressor, ama-molecular sieve beds, ama-pressure regulators, nezinhlelo zokulawula ezithuthukile eziqapha futhi zilungise amapharamitha okusebenza ngesikhathi sangempela. Lezi zinhlelo zinganwetshwa, futhi amandla okukhiqiza asukela kumayunithi amancane akhiqiza amamitha ayisikubhu ambalwa ngehora kuya ezakhiweni ezinkulu ezikwazi ukukhiqiza izinkulungwane zamamitha ayisikubhu ngehora. Ukuthembeka nokusebenza kahle kwalobu buchwepheshe kwenza kube usizo kakhulu ezimbonini ezinjengokunakekelwa kwezempilo, ukucutshungulwa kwezitini, ukuhlanzwa kwamanzi angcolile, nokukhiqizwa kwamakhemikhali.
