Ukukhiqizwa kwe-oxygen yezimboniimishini, njengoba negama lisho, iyimishini esetshenziswa ekukhiqizeni izimboni ukukhiqiza umoya-mpilo.
Ngakho iyiphi indlela yokukhiqiza umoya-mpilo wezimboni?
Ngokuvamile sivame ukusebenzisa indlela yokwenza umoya-mpilo ngokubola i-hydrogen peroxide noma i-potassium permanganate elabhorethri, enezici zokusabela okusheshayo, ukusebenza okulula nokuqoqwa okufanelekile komshini wokwenza umoya-mpilo wezimboni, kodwa izindleko ziphezulu futhi azikwazi ukukhiqizwa ngobuningi. amanani, ngakho-ke ingasetshenziswa elabhorethri kuphela.Ukukhiqizwa kwezimboni kudinga ukucabangela ukuthi ingabe ijeneretha ye-oksijini yezinto ezingavuthiwe iluphi uhlobo olutholakala kalula, noma ngabe intengo ishibhile, noma ngabe izindleko ziphansi, ukuthi ingakhiqizwa ngamanani amakhulu kanye nomthelela emvelweni.
Okulandelayo kuchaza izindlela eziqondile zeukukhiqizwa kwe-oxygen yezimboni.
1. Indlela yokuhlukanisa umoya obandayo
Izingxenye eziyinhloko zomoya umoya-mpilo ne-nitrogen.Ukusetshenziswa kwe-oxygen ne-nitrogen abilayo iphuzu kuhlukile, ukulungiswa komoya-mpilo ovela emoyeni kubizwa ngokuthi indlela yokuhlukanisa umoya.Okokuqala, umoya pre-ukupholisa, ukuhlanzwa (ukususa inani elincane umswakama, carbon dioxide, acetylene, hydrocarbon nezinye amagesi nothuli nezinye ukungcola emoyeni), bese onomfutho, selehlile, ukuze eziyishumi phezulu. ama-brand of oxygen generators into liquid air.
Khona-ke, kusetshenziswa umehluko phakathi kwamaphuzu abilayo omoya-mpilo ne-nitrogen, umoya owuketshezi uyahwamuka futhi ujiyezwe izikhathi ezimbalwa embhoshongweni wokukhipha umoya ukuze uhlukanise umoya-mpilo ne-nitrogen.Uma ungeza amanye amadivaysi engeziwe, ungaphinda ukhiphe i-argon, i-neon, i-helium, i-krypton, i-xenon namanye amagesi angenayo angavamile aqukethe okuncane kakhulu emoyeni.Umoya-mpilo okhiqizwa idivayisi yokuhlukanisa umoya ucindezelwa yi-compressor, futhi ekugcineni umoya-mpilo ocindezelwe ulayishwa kumasilinda omfutho ophezulu ukuze ugcinwe, noma uthuthelwe ngokuqondile ezimbonini nasezindaweni zokusebenzela ngamapayipi.
2. Indlela yokukhiqiza umoya we-molecular sieve (indlela ye-adsorption)
Kusetshenziswa izici zama-molecule e-nitrogen amakhulu kunama-oksijini, umoya-mpilo osemoyeni uhlukaniswa kusetshenziswa isisefo se-molecular esiklanywe ngokukhethekile.Okokuqala, i-compressor iphoqa umoya owomile ngesisefo se-molecular ungene ku-vacuum adsorber, ama-molecule e-nitrogen emoyeni akhangwa ngesisefo samangqamuzana, umoya-mpilo ungene kusikhangisi, lapho umoya-mpilo ku-adsorber ufinyelela inani elithile (ingcindezi ifinyelela ezingeni elithile). level), ungavula i-valve ye-oxygen ukuze ukhulule umoya-mpilo.
Ngemva kwesikhathi esithile, i-nitrogen ekhangiswa yisisefo samangqamuzana iyanda kancane kancane, amandla okukhangisa ayancipha, futhi ukuhlanzeka kwe-oksijini okukhiphayo kuyehla, ngakho-ke i-nitrogen ekhangiswa kusisefo samangqamuzana idinga ukumpontshwa ngepompo ye-vacuum, bese iphinda. inqubo engenhla.Le ndlela yokukhiqiza umoya-mpilo ibizwa nangokuthi indlela ye-adsorption.
