Ubuchwepheshe bokuhlukaniswa komoya ojulile we-cryogenic buyindlela ehlukanisa izingxenye eziyinhloko (i-nitrogen, i-oxygen kanye ne-argon) emoyeni ngokusebenzisa amazinga okushisa aphansi. Busetshenziswa kabanzi ezimbonini ezifana nensimbi, amakhemikhali, ezemithi kanye ne-elekthronikhi. Njengoba isidingo samagesi sikhula, ukusetshenziswa kobuchwepheshe bokuhlukaniswa komoya ojulile we-cryogenic nakho kuya ngokuya kusabalala. Lesi sihloko sizoxoxa kabanzi ngenqubo yokukhiqiza ukuhlukaniswa komoya ojulile we-cryogenic, okuhlanganisa nomgomo wayo wokusebenza, imishini eyinhloko, izinyathelo zokusebenza kanye nokusetshenziswa kwayo ezimbonini ezahlukahlukene.

Ukubuka konke kobuchwepheshe bokuhlukaniswa komoya i-Cryogenic

Isimiso esiyisisekelo sokuhlukaniswa komoya we-cryogenic ukupholisa umoya ube amazinga okushisa aphansi kakhulu (ngokuvamile ngaphansi kuka-150°C), ukuze izingxenye ezisemoyeni zihlukaniswe ngokwezindawo zazo zokubila ezahlukene. Ngokuvamile, iyunithi yokuhlukaniswa komoya we-cryogenic isebenzisa umoya njengento eluhlaza futhi idlula ezinqubweni ezifana nokucindezelwa, ukupholisa, kanye nokwandiswa, ekugcineni ihlukanise i-nitrogen, i-oxygen, kanye ne-argon emoyeni. Lobu buchwepheshe bungakhiqiza amagesi ahlanzekile kakhulu futhi, ngokulawula ngokunembile imingcele yenqubo, buhlangabezane nezidingo eziqinile zekhwalithi yegesi emikhakheni ehlukene yezimboni.

Iyunithi yokuhlukanisa umoya we-cryogenic ihlukaniswe izingxenye ezintathu eziyinhloko: i-air compressor, i-air pre-cooler, kanye ne-cold box. I-air compressor isetshenziselwa ukucindezela umoya ube nomfutho ophezulu (ngokuvamile i-5-6 MPa), i-pre-cooler inciphisa izinga lokushisa lomoya ngokupholisa, kanti i-cold box iyisici esiyinhloko senqubo yonke yokuhlukanisa umoya we-cryogenic, okuhlanganisa nombhoshongo wokuhlukaniswa, osetshenziselwa ukufeza ukuhlukaniswa kwegesi.

Ukucindezelwa komoya nokupholisa

Ukucindezela komoya kuyisinyathelo sokuqala ekuhlukaniseni umoya ocijile, okuhlose kakhulu ukucindezela umoya ngokucindezela komoya kube yingcindezi ephezulu (ngokuvamile i-5-6 MPa). Ngemva kokuba umoya ungene ohlelweni nge-compressor, izinga lokushisa lawo lizokhula kakhulu ngenxa yenqubo yokucindezela. Ngakho-ke, uchungechunge lwezinyathelo zokupholisa kumele lwenziwe ukuze kuncishiswe izinga lokushisa lomoya ocijile. Izindlela ezivamile zokupholisa zifaka phakathi ukupholisa ngamanzi nokupholisa umoya, futhi umphumela omuhle wokupholisa ungaqinisekisa ukuthi umoya ocijile awubangeli umthwalo ongadingekile emishinini ngesikhathi sokucubungula okulandelayo.

Ngemva kokuba umoya usupholile ngaphambi kokupholisa, ungena esigabeni esilandelayo sokupholisa ngaphambi kokupholisa. Isigaba sangaphambi kokupholisa ngokuvamile sisebenzisa i-nitrogen noma i-nitrogen ewuketshezi njengendawo yokupholisa, futhi ngemishini yokushintshanisa ukushisa, izinga lokushisa lomoya ocindezelwe liyancishiswa kakhulu, kulungiselela inqubo elandelayo ye-cryogenic. Ngokuphola ngaphambi kokupholisa, izinga lokushisa lomoya lingancishiswa liye eduze nezinga lokushisa loketshezi, okuhlinzeka ngezimo ezidingekayo zokuhlukaniswa kwezingxenye emoyeni.

Ukwandiswa kwezinga lokushisa eliphansi kanye nokuhlukaniswa kwegesi

Ngemva kokuba umoya ucindezelwe futhi upholisiwe kusengaphambili, isinyathelo esilandelayo esibalulekile ukwandiswa kwezinga lokushisa eliphansi kanye nokuhlukaniswa kwegesi. Ukwandiswa kwezinga lokushisa eliphansi kufezwa ngokwandisa ngokushesha umoya ocindezelwe nge-valve yokwandisa uye ekucindezelweni okuvamile. Ngesikhathi senqubo yokwandisa, izinga lokushisa lomoya lizokwehla kakhulu, lifinyelele izinga lokushisa loketshezi. I-nitrogen nomoya-mpilo emoyeni kuzoqala ukuncibilika emazingeni okushisa ahlukene ngenxa yokwehluka kwawo kwamazinga okubila.

Emishinini yokuhlukanisa umoya e-cryogenic, umoya oncibilikisiwe ungena ebhokisini elibandayo, lapho umbhoshongo wokuhlukaniswa uyingxenye eyinhloko yokuhlukaniswa kwegesi. Isimiso esiyinhloko sombhoshongo wokuhlukaniswa ukusebenzisa umehluko wamaphuzu okubila wezingxenye ezahlukene emoyeni, ngokusebenzisa igesi ekhuphuka futhi iwele ebhokisini elibandayo, ukuze kufezwe ukuhlukaniswa kwegesi. Iphuzu lokubila le-nitrogen lingu-195.8°C, elomoya-mpilo lingu-183°C, kanye nele-argon lingu-185.7°C. Ngokulungisa izinga lokushisa kanye nengcindezi embhoshongweni, ukuhlukaniswa kwegesi okuphumelelayo kungafinyelelwa.

Inqubo yokuhlukanisa igesi embhoshongweni wokuhlukaniswa inembile kakhulu. Ngokuvamile, uhlelo lombhoshongo wokuhlukaniswa olunezigaba ezimbili lusetshenziswa ukukhipha i-nitrogen, i-oxygen, kanye ne-argon. Okokuqala, i-nitrogen ihlukaniswa engxenyeni engenhla yombhoshongo wokuhlukaniswa, kuyilapho i-oxygen ewuketshezi kanye ne-argon kugxilwe engxenyeni engezansi. Ukuze kuthuthukiswe ukusebenza kahle kokuhlukanisa, kungafakwa i-cooler kanye ne-re-evaporator embhoshongweni, okungalawula ngokunembile inqubo yokuhlukanisa igesi.

I-nitrogen ekhishwe ivame ukuba nobumsulwa obuphezulu (ngaphezu kuka-99.99%), isetshenziswa kabanzi kwezensimbi, embonini yamakhemikhali, kanye ne-elekthronikhi. I-oxygen isetshenziswa kwezokwelapha, embonini yensimbi, nakwezinye izimboni ezisebenzisa amandla amaningi ezidinga i-oxygen. I-Argon, njengegesi engavamile, ivame ukukhishwa ngenqubo yokuhlukanisa igesi, ngobumsulwa obuphezulu futhi isetshenziswa kabanzi ekushiseni, ekuncibilikiseni, nasekusikeni nge-laser, phakathi kwezinye izinkambu zobuchwepheshe obuphezulu. Uhlelo lokulawula oluzenzakalelayo lungalungisa amapharamitha ahlukahlukene enqubo ngokuya ngezidingo zangempela, luthuthukise ukusebenza kahle kokukhiqiza, futhi lunciphise ukusetshenziswa kwamandla.

Ngaphezu kwalokho, ukwenziwa ngcono kohlelo lokuhlukanisa umoya olujulile olusebenzisa i-cryogenic kuhlanganisa nobuchwepheshe bokonga amandla kanye nokulawula ukukhishwa komoya. Isibonelo, ngokubuyisa amandla okushisa aphansi ohlelweni, imfucuza yamandla ingancishiswa futhi ukusebenza kahle kokusetshenziswa kwamandla kungathuthukiswa. Ngaphezu kwalokho, ngemithethonqubo yezemvelo eqinile, imishini yesimanje yokuhlukanisa umoya olujulile olusebenzisa i-cryogenic nayo inaka kakhulu ukunciphisa ukukhishwa kwegesi okuyingozi kanye nokuthuthukisa ubungane bemvelo benqubo yokukhiqiza.

Izicelo zokuhlukaniswa komoya okujulile kwe-cryogenic

Ubuchwepheshe bokuhlukanisa umoya obujulile obune-cryogenic abugcini nje ngokuba nezicelo ezibalulekile ekukhiqizweni kwamagesi ezimboni, kodwa futhi budlala indima ebalulekile emikhakheni eminingi. Ezimbonini zensimbi, umanyolo, kanye ne-petrochemical, ubuchwepheshe bokuhlukanisa umoya obujulile obune-cryogenic busetshenziselwa ukuhlinzeka ngamagesi ahlanzekile njenge-oxygen ne-nitrogen, okuqinisekisa izinqubo zokukhiqiza ezisebenzayo. Embonini ye-elekthronikhi, i-nitrogen enikezwa ukuhlukaniswa komoya okujulile okune-cryogenic isetshenziselwa ukulawula umoya ekukhiqizweni kwe-semiconductor. Embonini yezokwelapha, i-oxygen ehlanzekile kakhulu ibalulekile ekusekelweni kokuphefumula kweziguli.

Ngaphezu kwalokho, ubuchwepheshe bokuhlukaniswa komoya obujulile obune-cryogenic budlala indima ebalulekile ekugcinweni nasekuthuthweni komoya-mpilo owuketshezi kanye ne-nitrogen ewuketshezi. Ezimweni lapho amagesi anomfutho ophezulu engenakuthuthwa khona, umoya-mpilo oketshezi kanye ne-nitrogen ewuketshezi kunganciphisa ngempumelelo umthamo kanye nezindleko zokuthutha eziphansi.

Isiphetho

Ubuchwepheshe bokuhlukanisa umoya obujulile obune-cryogenic, obunamandla okuhlukanisa igesi asebenzayo futhi anembile, busetshenziswa kabanzi emikhakheni eyahlukene yezimboni. Ngokuthuthuka kobuchwepheshe, inqubo yokuhlukanisa umoya obujulile obune-cryogenic izoba ehlakaniphile futhi isebenzise kahle amandla, kuyilapho kuthuthukiswa ubumsulwa bokuhlukanisa igesi kanye nokusebenza kahle kokukhiqiza. Esikhathini esizayo, ukusungulwa kobuchwepheshe bokuhlukanisa umoya obujulile obune-cryogenic maqondana nokuvikelwa kwemvelo kanye nokubuyiselwa kwezinsiza nakho kuzoba yisiqondiso esibalulekile sokuthuthukiswa kwemboni.
