I-HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Ioksijini ecocekileyo kakhulu isetyenziswa kakhulu kwicandelo lezonyango, lemizi-mveliso, nelezenzululwazi. Uphuhliso oluqhubekayo lwetekhnoloji yayo yemveliso lukhokelele kwiimfuno eziphezulu zokucoceka nokusebenza kakuhle kweoksijini. Eli nqaku liza kwazisa iindlela ezahlukeneyo eziqhelekileyo zokuvelisa ioksijini ecocekileyo kakhulu, lihlalutya imigaqo yazo yokusebenza, izibonelelo kunye neengxaki, kunye neemeko ezifanelekileyo.

1. Indlela yoKwahlula umoya

Indlela yokwahlula umoya yenye yezona ndlela zisetyenziswa kakhulu ukuvelisa ioksijini ecocekileyo kakhulu. Umgaqo wayo ophambili kukwahlulahlula izinto ezahlukeneyo emoyeni kwiindawo ezahlukeneyo zokubila ngokusebenzisa iteknoloji yokupholisa ye-cryogenic.

1.1 Indlela Yokwahlukanisa Umoya Obandayo Onzulu

Indlela yokwahlula umoya obandayo ngokunzulu yiteknoloji yokuvelisa ioksijini kwimizi-mveliso evuthiweyo. Le ndlela isebenzisa umahluko kwiindawo zokubila zezixhobo ezahlukeneyo emoyeni phantsi koxinzelelo kunye namaqondo obushushu ahlukeneyo. Ngokusebenzisa amanqanaba amaninzi okucinezelwa, ukupholisa, kunye nokunyibilika, ioksijini, initrogen, kunye nezinye iigesi zahlulwa emoyeni. Isixhobo sokwahlula umoya obandayo ngokunzulu sisebenzisa iinqaba zokunyibilikisa ezinamanqanaba amaninzi ukuze ekugqibeleni sifumane ioksijini ecocekileyo ngokuphezulu enobumsulwa obungaphezulu kwe-99.5%.

Iingenelo zendlela yokwahlula umoya obandayo kukuba inokuvelisa ioksijini ecocekileyo kakhulu ngomlinganiselo omkhulu nangokuqhubekayo, kwaye ifanelekile kwizicelo zoshishino ezinemfuno ephezulu yeoksijini, njengokunyibilikisa intsimbi kunye neenkqubo zeekhemikhali. Iingxaki zayo kukuba utyalo-mali lokuqala lukhulu, ukusetyenziswa kwamandla kuphezulu, kwaye iimfuno zokugcinwa nokusebenza kwezixhobo ziphezulu.

1.2 Indlela Yokwahlula Uxinzelelo-Ulwandiso

Indlela yokwahlula-hlula umoya obandayo ngokucinezela yindlela yokuphucula indlela yokwahlula umoya obandayo ngokunzulu. Ngokucinezela umoya nokuwukhulisa ngokukhawuleza, umoya uyaphola kwaye ioksijini kunye nezinye izinto zahlulwe. Le ndlela inokufezekisa ubunyulu obuphezulu beoksijini, kodwa xa kuthelekiswa nokwahlula-hlula umoya obandayo ngokunzulu ngokwesiko, umthamo wezixhobo zayo uncinci kwaye ufanelekile kwiimfuno zemveliso yeoksijini encinci.

2. Indlela yokuNyusa i-Pressure Swing (PSA)

I-Pressure Swing Adsorption (PSA) yindlela esetyenziswa kakhulu kwimveliso yemizi-mveliso ye-high-purity oxygen. Umgaqo we-PSA kukusebenzisa iimpawu ze-adsorption ezikhethiweyo ze-adsorbents (ezifana ne-zeolite molecular sieves) kwi-nitrogen kunye ne-oxygen emoyeni. Phantsi koxinzelelo olwahlukeneyo, i-nitrogen iyafunxwa kwaye isuswe ngokwahlukeneyo, ngaloo ndlela ifumana i-high-purity oxygen.

Iingenelo zendlela ye-PSA kukuba izixhobo zayo zilula, ukuqalisa kuyakhawuleza, kwaye iindleko zokusebenza ziphantsi. Ayifuni nkqubo yokupholisa enzima, kwaye ke ngoko isetyenziswa kakhulu kwizixhobo zokuvelisa ioksijini encinci. Ubumsulwa beoksijini eveliswa yindlela ye-PSA buhlala buphakathi kwe-90% kunye ne-95%, kodwa ngokuphuculwa okufanelekileyo, ubumsulwa bunokwandiswa ngakumbi bube ngaphezulu kwe-99%.

Nangona kunjalo, iingxaki zendlela ye-PSA kukuba ukuveliswa kwe-itoxygen kunye nobunyulu kunqunyelwe kukusebenza kwe-adsorbent, kwaye ukusebenza kakuhle kwenkqubo kuchaphazeleka kukwaluphala kwe-adsorbent. Ke ngoko, le ndlela ifanelekile ngakumbi kumashishini okanye kumaziko ezonyango anemfuno encinci ye-oksijini.

Singabavelisi kunye nabathumela ngaphandle iyunithi yokwahlula umoya. Ukuba ufuna ukwazi okungakumbi ngathi:
