Imveliso yeoksijini yeshishiniizixhobo, njengoko negama lisitsho, sisixhobo esisetyenziswa kwimveliso yemizi-mveliso ukuvelisa ioksijini.
Ke yeyiphi indlela yokuvelisa ioksijini kwishishini?
Ngokuqhelekileyo siqhele ukusebenzisa indlela yokwenza i-oksijini ngokubola i-hydrogen peroxide okanye i-potassium permanganate kwilabhoratri, eneempawu zokusabela ngokukhawuleza, ukusebenza okulula kunye nokuqokelelwa okufanelekileyo komatshini wokwenza i-oksijini yoshishino, kodwa ixabiso liphezulu kwaye alikwazi ukuveliswa ngokubanzi. ubungakanani, ngoko ke ingasetyenziswa kuphela elabhoratri.Ukuveliswa kwemveliso kufuneka kuthathelwe ingqalelo ukuba ngaba i-oxygen generator ekrwada yintoni i-brand ekulula ukuyifumana, ingaba ixabiso lincinci, ingaba ixabiso liphantsi, ingaba liyakwazi ukuveliswa ngobuninzi kunye nefuthe kwindalo.
Oku kulandelayo kuchaza iindlela ezithile zeukuveliswa kweoksijini kwimizi-mveliso.
1. Indlela yokwahlula umkhenkce womoya
Amalungu aphambili omoya yioksijini kunye nenitrogen.Ukusetyenziswa kwe-oksijini kunye ne-nitrogen yokubilisa indawo yahlukile, ukulungiswa kwe-oksijini evela emoyeni kuthiwa yindlela yokwahlukana komoya.Okokuqala, umoya pre-ukupholisa, ukuhlanjululwa (ukususa isixa esincinane ukufuma, carbon dioxide, acetylene, hydrocarbons kunye nezinye iigesi kunye nothuli kunye nezinye izinto ezingcolileyo emoyeni), kwaye ngoko zicinezelwe, zipholile, ukuze phezulu ezilishumi. iibrendi zejenereyitha zeoksijini zibe ngumoya wolwelo.
Emva koko, usebenzisa umahluko phakathi kwamanqaku abilayo eoksijini kunye nenitrogen, umoya wolwelo uyaphuphuma kwaye ujikwe izihlandlo ezininzi kwinqaba yokukhutshwa kwedistillation ukwahlula ioksijini kunye nenitrogen.Ukuba wongeza ezinye izixhobo ezongezelelweyo, unokukhupha i-argon, i-neon, i-helium, i-krypton, i-xenon kunye nezinye iigesi ze-inert ezinqabileyo eziqulethe encinci kakhulu emoyeni.I-oksijini eveliswa sisixhobo sokwahlula umoya ixinzelelwe yi-compressor, kwaye ekugqibeleni i-oksijini ecinezelweyo ilayishwa kwiisilinda zoxinzelelo oluphezulu ukuze zigcinwe, okanye zihanjiswe ngokuthe ngqo kwiifektri kunye neeworkshops ngokusebenzisa imibhobho.
2. Indlela yokuvelisa i-oksijini ye-molecular (indlela ye-adsorption)
Kusetyenziswa iimpawu zeeathom zenitrogen ezinkulu kuneemolekyuli zeoksijini, ioksijini esemoyeni iyahlulwa kusetyenziswa isisefo semolekyuli eyilwe ngokukodwa.Okokuqala, icompressor inyanzela umoya owomileyo ngesihluzo semolekyuli kwi-vacuum adsorber, iimolekyuli zenitrogen ezisemoyeni zibhengezwa sisihluzo semolekyuli, ioksijini kwi-adsorber, xa ioksijini kwi-adsorber ifikelela kumyinge othile (uxinzelelo lufikelela kwinqanaba elithile. kwinqanaba), unokuvula ivalve yeoksijini ukukhulula ioksijini.
Emva kwexesha elithile, initrogen edityaniswe sisihluzo semolekyuli iyanda ngokuthe ngcembe, amandla e-adsorption ayancipha, kwaye ukucoceka kweoksijini ephumayo kuyehla, ngoko ke initrogen edityaniswe kwisihluzo semolekyuli ifuna ukumpontshelwa ngaphandle ngempompo yokufutha, emva koko iphindaphinde. le nkqubo ingentla.Le ndlela yokuvelisa ioksijini ikwabizwa ngokuba yi-adsorption method.
