Ubuchwephesha bokuhlukana komoya obunzulu be-cryogenic yindlela eyahlula amacandelo aphambili (i-nitrogen, i-oksijini kunye ne-argon) emoyeni ngamaqondo aphantsi. Isetyenziswa kakhulu kumashishini afana nentsimbi, iikhemikhali, amayeza kunye ne-elektroniki. Ngokunyuka kwemfuno yeegesi, ukusetyenziswa kobuchwephesha bokwahlukana komoya obunzulu be-cryogenic nako kuya kusasazeka ngakumbi. Eli nqaku liza kuxubusha ngokucokisekileyo inkqubo yokuvelisa ukuhlukana komoya onzulu we-cryogenic, kubandakanywa nomgaqo wayo wokusebenza, izixhobo eziphambili, amanyathelo okusebenza kunye nokusetyenziswa kwayo kumashishini ahlukeneyo.

Isishwankathelo seCryogenic Air Separation Technology

Umgaqo osisiseko wokuhlukana komoya we-cryogenic kukupholisa umoya ukuya kumaqondo okushisa aphantsi kakhulu (ngokubanzi ngaphantsi kwe-150 ° C), ukwenzela ukuba amacandelo emoyeni angakwazi ukuhlukana ngokweendawo zabo zokubilisa ezahlukeneyo. Ngokuqhelekileyo, iyunithi yokwahlula umoya we-cryogenic isebenzisa umoya njengento eluhlaza kwaye ihamba ngeenkqubo ezifana nokunyanzeliswa, ukupholisa, kunye nokwandiswa, ekugqibeleni ukwahlula i-nitrogen, i-oksijini kunye ne-argon emoyeni. Le teknoloji inokuvelisa iigesi ezicocekileyo kwaye, ngokulawula ngokuchanekileyo iiparameters zenkqubo, ihlangabezana neemfuno ezingqongqo kumgangatho wegesi kwiindawo ezahlukeneyo zoshishino.

Iyunithi yokwahlula umoya we-cryogenic yohlulwe yangamacandelo amathathu aphambili: icompressor yomoya, i-air pre-cooler, kunye nebhokisi ebandayo. Icompressor yomoya isetyenziselwa ukucinezela umoya kuxinzelelo oluphezulu (ngokuqhelekileyo i-5-6 MPa), i-pre-cooler inciphisa ubushushu bomoya ngokupholisa, kwaye ibhokisi ebandayo iyona nxalenye engundoqo yenkqubo yokwahlukana komoya yonke ye-cryogenic, kubandakanywa nenqaba yokwahlukana, esetyenziselwa ukufezekisa ukwahlukana kwegesi.

Uxinzelelo lomoya kunye nokupholisa

Ukunyanzeliswa komoya linyathelo lokuqala ekuhlukaneni komoya we-cryogenic, ngokukodwa kujolise ukucinezela umoya kuxinzelelo lwe-atmospheric ukuya kuxinzelelo oluphezulu (ngokuqhelekileyo i-5-6 MPa). Emva kokuba umoya ungene kwinkqubo nge-compressor, ukushisa kwayo kuya kwanda kakhulu ngenxa yenkqubo yoxinzelelo. Ngoko ke, uchungechunge lwamanyathelo okupholisa kufuneka lwenziwe ukunciphisa ubushushu bomoya ocinezelweyo. Iindlela zokupholisa eziqhelekileyo ziquka ukupholisa kwamanzi kunye nokupholisa umoya, kunye nesiphumo esihle sokupholisa sinokuqinisekisa ukuba umoya oxinyiweyo awubangeli umthwalo ongeyomfuneko kwisixhobo ngexesha lokucubungula okulandelayo.

Emva kokuba umoya upholisiwe ngaphambili, ungena kwinqanaba elilandelayo lokupholisa kwangaphambili. Inqanaba lokupholisa kwangaphambili lidla ngokusebenzisa i-nitrogen okanye i-nitrogen engamanzi njengendlela yokupholisa, kwaye ngezixhobo zokutshintshiselana kobushushu, ubushushu bomoya ocinezelweyo buyancipha ngakumbi, bulungiselela inkqubo ye-cryogenic elandelayo. Ngokusebenzisa ukupholisa kwangaphambili, ukushisa komoya kungancitshiswa ukuvala ukushisa kwe-liquefaction, ukubonelela ngeemeko eziyimfuneko zokuhlukana kwamacandelo emoyeni.

Ukwandiswa kobushushu obuphantsi kunye nokwahlulwa kwegesi

Emva kokuba umoya uxinzelelwe kwaye upholile ngaphambili, inyathelo elilandelayo eliphambili kukunyuka kweqondo lokushisa eliphantsi kunye nokuhlukana kwegesi. Ukwandiswa kobushushu obuphantsi kufumaneka ngokwandisa ngokukhawuleza umoya ocinezelweyo ngokusebenzisa ivalve yokwandisa ukuya kuxinzelelo oluqhelekileyo. Ngethuba lenkqubo yokwandisa, ubushushu bomoya buya kuhla kakhulu, bufikelele kwiqondo lokushisa le-liquefaction. I-nitrogen kunye neoksijini esemoyeni iya kuqala ukunyibilika kumaqondo obushushu ahlukeneyo ngenxa yokubilisa kwayo umahluko.

Kwizixhobo zokwahlula umoya we-cryogenic, umoya omanzi ungena kwibhokisi ebandayo, apho inqaba yokwahlula inxalenye ephambili yokuhlukana kwegesi. Umgaqo ongundoqo we-fraction tower kukusebenzisa iiyantlukwano zamanqaku abilayo amacandelo ahlukeneyo emoyeni, ngokunyuka kwerhasi nokuwa kwibhokisi ebandayo, ukuphumeza ukwahlulwa kwerhasi. Indawo yokubila yenitrogen yi -195.8°C, eye oxygen yi -183°C, kwaye eyeargon yi -185.7°C. Ngokulungelelanisa ubushushu kunye noxinzelelo kwinqaba, ukuhlukana kwegesi okusebenzayo kunokufezekiswa.

Inkqubo yokwahlula igesi kwinqaba yokwahlulwa ichaneke kakhulu. Ngokuqhelekileyo, inkqubo ye-fraction tower enemigangatho emibini isetyenziselwa ukukhupha i-nitrogen, i-oksijini kunye ne-argon. Okokuqala, i-nitrogen ihlukaniswe kwindawo ephezulu ye-fractionation tower, ngelixa i-oksijeni yamanzi kunye ne-argon igxininiswe kwindawo engezantsi. Ukuphucula ukusebenza kakuhle kokwahlula, i-cooler kunye ne-re-evaporator inokongezwa kwinqaba, enokuthi ilawule ngakumbi ngokuchanekileyo inkqubo yokwahlukana kwegesi.

I-nitrogen ekhutshiweyo idla ngokucoceka okuphezulu (ngaphezulu kwe-99.99%), isetyenziswa ngokubanzi kwi-metallurgy, kushishino lweekhemikhali, kunye ne-electronics. I-oksijeni isetyenziselwa unyango, imboni yensimbi, kunye namanye amashishini asebenzisa amandla amaninzi afuna i-oxygen. I-Argon, njengegesi enqabileyo, idla ngokukhutshwa ngenkqubo yokwahlula igesi, ngokucoceka okuphezulu kwaye isetyenziswe ngokubanzi kwi-welding, smelting, kunye ne-laser cutting, phakathi kwezinye iindawo eziphezulu zobuchwepheshe. Inkqubo yolawulo oluzenzekelayo inokulungelelanisa iiparamitha zenkqubo ngokweemfuno zangempela, yandise ukusebenza kakuhle kwemveliso, kunye nokunciphisa ukusetyenziswa kwamandla.

Ukongeza, ukulungiswa kwenkqubo yokwahlula umoya ye-cryogenic enzulu ikwabandakanya ukonga amandla kunye nobuchwepheshe bokulawula ukukhutshwa. Umzekelo, ngokufumana kwakhona amandla obushushu obuphantsi kwisixokelelwano, inkcitho yamandla inokuncitshiswa kwaye ukusebenza kakuhle kokusetyenziswa kwamandla kunokuphuculwa. Ngaphezu koko, kunye nemithetho engqongqo yokusingqongileyo, izixhobo zanamhlanje zokwahlula umoya ezinzulu ze-cryogenic nazo zinika ingqwalasela engakumbi ekunciphiseni ukukhutshwa kwerhasi eyingozi kunye nokuphucula ukulunga kokusingqongileyo kwenkqubo yemveliso.

Izicelo zokuhlukana komoya onzulu we-cryogenic

Ubuchwephesha bokuhlukana komoya obunzulu be-cryogenic abunayo kuphela izicelo ezibalulekileyo kwimveliso yeegesi zamashishini, kodwa idlala indima ebalulekileyo kwiinkalo ezininzi. Kumashishini ensimbi, isichumisi, kunye ne-petrochemical, iteknoloji yokwahlula umoya ye-cryogenic enzulu isetyenziselwa ukubonelela ngeegesi ezicocekileyo ezifana ne-oksijini kunye ne-nitrogen, ukuqinisekisa iinkqubo ezisebenzayo zokuvelisa. Kumashishini ombane, initrogen ebonelelwa ngokwahlukana komoya onzulu we-cryogenic isetyenziselwa ukulawula umoya kwimveliso ye-semiconductor. Kwishishini lezonyango, i-oksijini ecocekileyo ibalulekile kwinkxaso yokuphefumula yezigulane.

Ukongeza, itekhnoloji enzulu yokwahlula umoya we-cryogenic nayo idlala indima ebalulekileyo ekugcinweni nasekuthuthweni kweoksijini engamanzi kunye nenitrogen engamanzi. Kwiimeko apho i-high-pressure gases ayikwazi ukuthuthwa, i-oksijini engamanzi kunye ne-nitrogen engamanzi inokunciphisa ngokufanelekileyo umthamo kunye neendleko zokuthutha eziphantsi.

Ukuqukumbela

Itekhnoloji enzulu yokwahlula umoya we-cryogenic, enobuchule bayo obufanelekileyo kunye nobuchanekileyo bokwahlula igesi, isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zoshishino. Ngokuhambela phambili kwetekhnoloji, inkqubo yokwahlula umoya enzulu ye-cryogenic iya kuba nobukrelekrele ngakumbi kwaye isebenzise amandla, ngelixa iphucula ukucoceka kokuhlukana kwegesi kunye nokusebenza kakuhle kwemveliso. Kwixesha elizayo, ukusungulwa kwetekhnoloji yokwahlula umoya enzulu ye-cryogenic ngokwemiqathango yokukhuselwa kwendalo kunye nokubuyiswa kobutyebi kwakhona kuya kuba ngumgaqo ophambili wophuhliso loshishino.
