Ukukhiqizwa komoya-mpilo kuyinqubo ebucayi ezimbonini ezihlukahlukene, kusukela kwezokwelapha kuya kwezicelo zezimboni. Amasu amabili avelele asetshenziselwa le njongo yi-PSA (I-Pressure Swing Adsorption) kanye ne-VPSA (I-Vacuum Pressure Swing Adsorption). Zombili lezi zindlela zisebenzisa izisefo zamangqamuzana ukuze zihlukanise umoya-mpilo nomoya, kodwa ziyehluka ezinhlelweni zazo zokusebenza nasekusetshenzisweni kwazo.
I-PSA Oxygen Production
I-PSA generator ye-oxygenkuhlanganisa ukusetshenziswa kwezisefo zamangqamuzana ukuze ukhethe ngokukhetha i-nitrogen emoyeni ngaphansi kwengcindezi ephezulu futhi iyikhulule ngaphansi kwengcindezi ephansi. Le nqubo i-cyclical, evumela ukukhiqizwa kwe-oksijeni okuqhubekayo. Isistimu ngokuvamile ihlanganisa i-compressor yomoya ukuze inikeze umoya odingekayo wokucindezela okuphezulu, umbhede we-molecular sieve, kanye nesistimu yokulawula ukuphatha imijikelezo ye-adsorption ne-desorption.
Izingxenye ezibalulekile zesistimu ye-PSA zifaka i-compressor yomoya, umbhede we-molecular sieve, kanye nesistimu yokulawula. I-compressor yomoya inikeza umoya wokucindezela okuphezulu, odlula embhedeni we-sieve we-molecular. Isisefo se-molecular sikhanga i-nitrogen, ishiya umoya-mpilo ukuthi uqoqwe. Ngemva kokufinyelela ukugcwala, ukucindezela kuyancishiswa, okuvumela ukuba i-nitrogen ikhululwe futhi isisefo sivuselelwe umjikelezo olandelayo.
I-VPSA Oxygen Production
I-VPSA, ngakolunye uhlangothi, isebenza ngaphansi kwezimo ze-vacuum ukuthuthukisa ukusebenza kahle kwe-adsorption ye-molecular sieve kanye nezinqubo ze-desorption. Le ndlela isebenzisa inhlanganisela yezisefo zamangqamuzana namaphampu e-vacuum ukuze kuzuzwe amazinga aphezulu okuhlanzeka komoya-mpilo. Isitshalo se-oxygen ye-VPSA sihlanganisa ipompo ye-vacuum, umbhede we-molecular sieve, kanye nesistimu yokulawula.
Inqubo ye-VPSA iqala ngokudonselwa komoya ohlelweni ngaphansi kwezimo ze-vacuum. Isisefo se-molecular sikhanga i-nitrogen nokunye ukungcola, kushiye umoya-mpilo. Uma isisefo sesigcwele, ivacuum isetshenziswa ukuze kukhululwe amagesi adsorbed, kuvuselelwe isisefo ukuze sisetshenziswe ngokuqhubekayo.
Ukuqhathanisa Nezicelo
Kokubili i-PSA ne-VPSA zisebenza ngempumelelo ekukhiqizeni umoya-mpilo ohlanzekile, kodwa ziyahlukahluka ngezidingo zabo zokusebenza kanye nesilinganiso. Amasistimu e-PSA ngokuvamile mancane futhi ayaphatheka kakhudlwana, okuwenza afanelekele izinhlelo zokusebenza lapho isikhala silinganiselwe, njengezikhungo zezokwelapha noma izilungiselelo zezimboni ezincane. Izinhlelo ze-VPSA, nakuba zinkulu futhi ziyinkimbinkimbi, ziyakwazi ukukhiqiza ivolumu ephezulu ye-oxygen futhi zivame ukusetshenziselwa izinhlelo zokusebenza ezinkulu zezimboni.
Mayelana nokusebenza kahle, izinhlelo ze-VPSA zivame ukonga amandla ngenxa yezimo ze-vacuum, ezinciphisa amandla adingekayo ukuze kukhishwe amandla. Kodwa-ke, izindleko zokuqala zokusetha nokusebenza kwezinhlelo ze-VPSA ziphezulu uma kuqhathaniswa nezinhlelo ze-PSA.
Isiphetho
I-PSA kanye ne-VPSA ijeneretha ye-oxygen yezimboni inikeza izindlela ezinokwethenjelwa neziphumelelayo zokukhiqiza umoya-mpilo, ngayinye inezinzuzo zayo eziyingqayizivele kanye nezicelo. Ukukhetha phakathi kwalokhu kokubili kuvame ukuncika ezidingweni ezithile zohlelo lokusebenza, okuhlanganisa umthamo womoya-mpilo odingekayo, izinga lokuhlanzeka elidingekayo, nendawo etholakalayo kanye nesabelomali. Zombili lezi zindlela zifaka isandla kakhulu ezidingweni ezihlukahlukene zezimboni nasezikhungweni zezokwelapha, ziqinisekisa ukutholakala komoyampilo okuqhubekayo lapho udingeka khona kakhulu.
