Dongosolo la okosijeni la PSA lili ndi chizolowezi chosintha chipangizo cholekanitsa mpweya chotsika kutentha m'munda wolekanitsa mpweya wapakati ndi waung'ono, chifukwa cha ndalama zochepa zomwe zimagwiritsidwa ntchito, kugwiritsa ntchito mphamvu zochepa, komanso kugwiritsa ntchito mosavuta. Sefa ya okosijeni imagwiritsa ntchito liwiro losiyanasiyana la nayitrogeni ndi mpweya kuti ipange mpweya wochuluka wa okosijeni ndi mpweya.
Pa zipangizo za VSA ndi VPSA zomwe zimakhala ndi mphamvu yochepa yoyamwa madzi, sieve ya lithiamu molecular kuti ipange mpweya wabwino ingathandize kwambiri kupanga mpweya wabwino ndikuchepetsa kugwiritsa ntchito mphamvu ya mpweya wabwino.
PSA yaying'ono yopangira mpweya wamankhwala
Mpweya umasefedwa kudzera mu chipangizo cholowetsa mpweya musanalowe mu compressor, kenako umapita ku nsanja ya molecular sieve kuti mpweya ndi nayitrogeni zilekanitsidwe. Mpweya umadutsa bwino kudzera mu nsanja ya molecular sieve kupita ku nsanja ya sieve, ndipo nayitrogeni imalowetsedwa ndi mamolekyu, ndipo umatulutsidwa mumlengalenga kudzera mu valavu yolekanitsa. Mpweya ukapitirira kukulitsa chiyero cha nsanja ya sieve, umadutsa mu chubu chotumizira mpweya kuti wogwiritsa ntchito awonjezere kuyamwa kwa mpweya. Kuchuluka kwa kayendedwe ka mpweya kumayendetsedwa ndi valavu yowongolera kayendedwe ka mpweya, ndikunyowa kudzera mu thanki yamadzi yonyowa.
JZ molecular sieve imatha kufika pa chiyero cha mpweya cha 92-95%.
PSA jenereta ya mpweya wa mafakitale
Dongosolo lopangira okosijeni limakhala ndi compressor ya mpweya, choziziritsira mpweya, thanki yosungira mpweya, valavu yosinthira, adsorbent, ndi thanki yolinganiza mpweya. Mpweya wosaphika ukachotsa tinthu ta fumbi kudzera mu gawo la fyuluta, compressor ya mpweya imapanikizika mpaka 3 ~ 4barg ndikulowa mu imodzi mwa nsanja yolandirira mpweya. Nsanja yolandirira mpweya imadzazidwa ndi adsorbent, momwe chinyezi, carbon dioxide, ndi zinthu zina zingapo za mpweya zimalowetsedwa pakhomo la adsorbent, kenako nayitrogeni imalowetsedwa ndi sieve ya molekyulu yodzazidwa pamwamba pa alumina yoyatsidwa.
Mpweya wa okosijeni (kuphatikizapo argon) ndi gawo losayamwa kuchokera pamwamba pa mpweya wa adsorbent ngati mpweya wopangidwa kupita ku thanki yoyezera mpweya wa okosijeni. Mpweya wa adsorbent ukayamwa pamlingo winawake, mpweya wa adsorbent udzafika pamlingo wokwanira, kenako udzatsitsidwa kudzera mu valavu yosinthira, madzi oyamwa, carbon dioxide, nayitrogeni ndi zinthu zina zochepa za mpweya zimatulutsidwa mumlengalenga, ndipo mpweya wa adsorbent umabwezeretsedwanso.
