Ukuveliswa kwe-oksijeni yinkqubo ebalulekileyo kumashishini ahlukeneyo, ukusuka kwizonyango ukuya kwizicelo zoshishino. Iindlela ezimbini ezibalaseleyo ezisetyenziselwa le njongo zi-PSA (Uxinzelelo Swing Adsorption) kunye neVPSA (iVacuum Pressure Swing Adsorption). Zombini ezi ndlela zisebenzisa iisefu zemolekyuli ukwahlula ioksijini emoyeni, kodwa ziyahluka kwiindlela zokusebenza kunye nokusetyenziswa kwazo.
Imveliso ye-Oxygen ye-PSA
PSA generator oksijiniibandakanya ukusetyenziswa kwe-sieves ye-molecular ukukhetha ngokukhetha i-nitrogen emoyeni phantsi koxinzelelo oluphezulu kwaye uyikhulule phantsi koxinzelelo oluphantsi. Le nkqubo ijikeleza, ivumela ukuveliswa kweoksijini okuqhubekayo. Inkqubo ngokuqhelekileyo ibandakanya i-compressor yomoya ukubonelela ngomoya ofunekayo woxinzelelo oluphezulu, ibhedi ye-molecular sieve, kunye nenkqubo yokulawula ukulawula i-adsorption and desorption cycles.
Amacandelo aphambili enkqubo ye-PSA abandakanya i-compressor yomoya, ibhedi ye-molecular sieve, kunye nenkqubo yokulawula. I-compressor yomoya inika umoya woxinzelelo oluphezulu, odlula kwi-molecular sieve bed. I-molecular sieve ibhengeza initrogen, ishiya ioksijini ukuba iqokelelwe. Emva kokufikelela kwi-saturation, uxinzelelo luyancitshiswa, luvumela ukuba i-nitrogen ikhululwe kwaye i-sieve ihlaziywe kumjikelezo olandelayo.
VPSA Ukuveliswa kweoksijini
VPSA, kwelinye icala, isebenza phantsi kweemeko ze-vacuum ukuphucula ukusebenza kakuhle kwe-molecular sieve's adsorption and desorption systems. Le ndlela isebenzisa indibaniselwano ye-molecular sieves kunye neepompo ze-vacuum ukufezekisa amanqanaba aphezulu okucoceka kwe-oksijini. Isityalo se-oxygen ye-VPSA sibandakanya ipompo yokucoca, ibhedi ye-molecular sieve, kunye nenkqubo yokulawula.
Inkqubo ye-VPSA iqala ngokutsalwa komoya kwinkqubo phantsi kweemeko ze-vacuum. I-molecular sieve ibhengeza initrogen kunye nezinye izinto ezingcolileyo, ishiya ioksijini. Emva kokuba i-sieve ihluthe, i-vacuum isetyenziselwa ukukhulula i-gases ye-adsorbed, ivuselela i-sieve ukuze isetyenziswe ngakumbi.
Uthelekiso kunye nezicelo
Zomibini i-PSA kunye ne-VPSA zisebenza kakuhle ekuveliseni i-oksijeni ephezulu, kodwa ziyahluka kwiimfuno zabo zokusebenza kunye nomlinganiselo. Iinkqubo ze-PSA ngokuqhelekileyo zincinci kwaye ziphathwa ngakumbi, zizenza zilungele izicelo apho indawo incinci, njengezibonelelo zonyango okanye iisetingi ezincinci zemizi-mveliso. Iinkqubo ze-VPSA, ngelixa zinkulu kwaye zinzima ngakumbi, ziyakwazi ukuvelisa umthamo ophezulu we-oksijini kwaye zihlala zisetyenziswa kwizicelo ezinkulu zoshishino.
Ngokubhekiselele kokusebenza kakuhle, iinkqubo ze-VPSA ngokubanzi zinamandla ngakumbi ngenxa yeemeko ze-vacuum, ezinciphisa amandla afunekayo kwi-desorption. Nangona kunjalo, iindleko zokuqala zokuseta kunye nokusebenza kweenkqubo zeVPSA ziphezulu xa kuthelekiswa neenkqubo zePSA.
Ukuqukumbela
I-PSA kunye ne-VPSA ye-oxygen generator ye-oxygen inikezela ngeendlela ezithembekileyo nezisebenzayo zokuvelisa i-oksijini, nganye ineenzuzo zayo ezizodwa kunye nokusetyenziswa. Ukhetho phakathi kwezi zibini luhlala luxhomekeke kwiimfuno ezithile zesicelo, kubandakanywa umthamo we-oksijini efunekayo, izinga lokucoceka elifunekayo, kunye nendawo ekhoyo kunye nohlahlo lwabiwo-mali. Zombini iindlela zifaka isandla kakhulu kwiimfuno ezahlukeneyo zamashishini kunye nezibonelelo zonyango, ukuqinisekisa ukunikezelwa kwe-oksijini eqhubekayo apho ifuneka kakhulu.
