Intshayelelo emfutshane yePSA yesiZukulwana seNitrojeni

I-PSA (i-Pressure Swing Adsorption) iijenereyitha zenitrogen ziinkqubo ezisetyenziselwa ukuvelisa igesi yenitrogen ngokwahlula emoyeni. Ngokuqhelekileyo zisetyenziswa kumashishini ahlukeneyo kunye nezicelo apho unikezelo oluhambelanayo lokucoceka kwe-99-99.999% ye-nitrogen iyadingeka.

Umgaqo osisiseko aPSA nitrogen jenereyithaibandakanya ukusetyenziswa kwe-adsorption kunye ne-desorption cycle. Nantsi indlela eqhele ukusebenza ngayo:

I-Adsorption: Inkqubo iqala ngokugqithiswa komoya ocinezelweyo ngenqanawa enezinto ezibizwa ngokuba yi-molecular sieve. I-molecular sieve inobudlelwane obuphezulu beemolekyuli zeoksijini, ukuyivumela ukuba ikhethe ngokukhethayo ngelixa ivumela iimolekyuli zenitrogen ukuba zidlule.

Ukwahlulwa kweNitrojeni: Njengoko umoya ocinezelweyo udlula kwibhedi ye-molecular sieve, iimolekyuli zeoksijini ziyabhengezwa, zishiya ngasemva igesi enenitrogen. Igesi yenitrogen iyaqokelelwa kwaye igcinwe ukuze isetyenziswe.

I-Desorption: Emva kwexesha elithile, ibhedi ye-molecular sieve igcwele i-oxygen. Ngeli xesha, inkqubo ye-adsorption imisiwe, kwaye uxinzelelo kwinqanawa luyancitshiswa. Oku kuncitshiswa koxinzelelo kubangela ukuba i-adsorbed oxygen molecules ikhutshwe kwi-molecular sieve, ivumela ukuba ihlanjululwe kwinkqubo.

Ukuhlaziywa kwakhona: Emva kokuba i-oksijeni ihlanjululwe, uxinzelelo luyanda kwakhona, kwaye ibhedi ye-molecular sieve ilungele omnye umjikelezo we-adsorption. I-adsorption etshintshanayo kunye ne-desorption cycles iyaqhubeka nokuvelisa unikezelo oluqhubekayo lwegesi yenitrogen.

PSA iijenereyitha zenitrogenziyaziwa ngokusebenza kwazo kunye nokuthembeka. Bangakwazi ukuvelisa i-nitrogen kunye namanqanaba aphezulu okucoceka, ngokuqhelekileyo ukusuka kwi-95% ukuya kwi-99.999%. Inqanaba lokucoceka eliphunyeziweyo lixhomekeke kwiimfuno ezithile zesicelo.

Ezi generator zisetyenziswa kakhulu kumashishini afana nokupakishwa kokutya, ukwenziwa kombane, amayeza, ukusetyenzwa kweekhemikhali, ioyile negesi, kunye nabanye abaninzi. Banikela iingenelo ezifana kwisiza imveliso nitrogen, ukonga iindleko xa kuthelekiswa iindlela zonikezelo nitrogen yemveli, kunye nokukwazi ukwenza amanqanaba nitrogen ubumsulwa ngokusekelwe iimfuno ezithile.
