Ukumbiwa kwamalahle nokugcinwa kwawo
Ezimayini zamalahle, lapho umlilo uqhuma endaweni yokushiswa kwegesi ye-goaf, inhlekelele enkulu ukuqhuma kwegesi exubile yangaphakathi. Ukugcwaliswa kwe-nitrogen kungalawula okuqukethwe komoya-mpilo kugesi exubile engaphansi kuka-12%, okungagcini nje ngokucindezela amathuba okuqhuma, kodwa futhi okuvimbela amalahle ekushiseni okuzenzakalelayo, okwenza indawo yokusebenza iphephe.
Ukukhishwa kukawoyela negesi yemvelo
I-nitrogen iyigesi ejwayelekile esetshenziselwa ukucindezela uwoyela negesi evela emithonjeni emikhulu/ezindaweni zokugcina igesi yemvelo. Ukusebenzisa izici ze-nitrogen uqobo ukugcina ingcindezi yendawo yokugcina uwoyela, isigaba esixubile kanye nobuchwepheshe bokufuduka kwamafutha angaxubeki kanye nokukhipha amanzi adonsela phansi kungakhulisa kakhulu ukubuyiswa kwamafutha, okubaluleke kakhulu ekuqiniseni ukukhiqizwa kwamafutha kanye nokwandisa ukukhiqizwa kwamafutha.
Amakhemikhali kaphethiloli kanye ne-petrochemicals
Ngokwezici zegesi engasebenzi, i-nitrogen ingakha umoya ongasebenzi ngesikhathi sokucubungula, ukugcinwa kanye nokudluliselwa kwezinto ezivuthayo, isuse futhi ithathe indawo yamagesi anobuthi navuthayo ayingozi.
Imboni yamakhemikhali
I-nitrogen iyinto ebalulekile eluhlaza yemicu yokwenziwa (inayiloni, i-acrylic), i-resin yokwenziwa, irabha yokwenziwa, njll. I-nitrogen ingasetshenziswa futhi ukwenza umanyolo wamakhemikhali, njenge-ammonia bicarbonate, i-ammonium chloride, njll.
Imithi
Embonini yezemithi, inqubo yokugcwalisa i-ammonia ingathuthukisa ngempumelelo ikhwalithi yemithi, kungaba ukufuthwa, ukujova ngamanzi, ukujova ngempuphu, imishini yokuqandisa noma ukukhiqizwa koketshezi ngomlomo, njll.
Izinto zikagesi, ugesi, izintambo
Amabhalbhu okukhanya agcwele. Gcwalisa ibhalbhu ngomkhathi ukuze uvimbele ukushiswa kwe-tungsten filament futhi wehlise izinga lokuhwamuka kwe-tungsten filament, ngaleyo ndlela wandise impilo yebhalbhu.
Amafutha adliwayo namafutha
Ithangi lokugcina uwoyela eligcwele i-fluorine ligcwaliswa nge-nitrogen ethangini lokugcina uwoyela futhi likhipha umoya ovela ethangini lokugcina uwoyela ukuze kuvinjelwe uwoyela ukuthi ungangcoliswa, ngaleyo ndlela kuqinisekiswe ukugcinwa okuphephile kwamafutha. Uma okuqukethwe yi-nitrogen kuphezulu futhi okuqukethwe yi-oxygen kuphansi, kungcono ukugcina okomile. Kungashiwo ukuthi okuqukethwe yi-nitrogen kunomthelela omkhulu ekugcinweni kwamafutha adliwayo kanye namafutha.
Ukudla neziphuzo
Ukuze kube lula ukugcina, okusanhlamvu, amathini, izithelo, iziphuzo, njll. kuvame ukugcwaliswa nge-nitrogen ukuvimbela ukugqwala.
Imboni yamakhemikhali epulasitiki
I-nitrogen ifakwa enkambisweni yokubumba nokupholisa izingxenye zepulasitiki, kusetshenziswa i-nitrogen ukunciphisa ukuguquka okubangelwa ukucindezela izingxenye zepulasitiki, okuholela ebukhulu bezingxenye zepulasitiki obuzinzile nobunembile. Ukusebenzisa ukubumba nge-nitrogen kungathuthukisa ikhwalithi kanye nokuguquguquka komklamo wemikhiqizo ebunjiwe nge-injection. Ngokwezimo zenqubo ezahlukene, ubumsulwa be-nitrogen obudingekayo ekubumbeni nge-injection yepulasitiki buhlukile. Ngakho-ke, akufaneleki ukusebenzisa i-nitrogen ebhodleleni. Kungcono ukusebenzisa ijeneretha ye-nitrogen yokucindezela ukujiya endaweni ukuze unikeze i-nitrogen ngqo.
Ukukhiqizwa kwerabha kanye ne-resin
Inqubo yokuqothula i-nitrogen yerabha, okungukuthi, ngesikhathi senqubo yokuqothula irabha, i-nitrogen iyanezelwa ukuze isebenze njengegesi evikelayo.
Ukukhiqizwa kwamathayi ezimoto
Ukugcwalisa amathayi nge-nitrogen kungathuthukisa ukuzinza kanye nenduduzo yamathayi, kuvimbele ukubhoboka, futhi kwandise impilo yamathayi. I-nitrogen ayinawo umsindo ofanele. Ukusebenzisa i-nitrogen kunganciphisa umsindo wamathayi futhi kuthuthukise induduzo yokushayela.
Ukwelashwa kwensimbi nokushisa
Igesi evikelayo yokusatshalaliswa okuqhubekayo, ukugoqa okuqhubekayo kanye nokufakwa kwensimbi: uphahla lwe-converter kanye nephansi kufanelekile ekuvutheni i-ammonia yokwenza insimbi, ukuvala insimbi ye-converter, ukuvala i-blast furnace top, ukwenza insimbi ye-blast furnace ecoliwe, njll.
Izinto ezintsha
Ukuvikelwa komoya wokwelashwa kokushisa kwezinto ezintsha nezinto ezihlanganisiwe.
Izindiza kanye nezindiza
Igesi yokushisa evamile i-nitrogen isetshenziselwa ukuvikela izindiza, irokhethi nezinye izingxenye ekuqhumeni, isikhuthazi sikaphethiloli werokhethi, igesi yokushintsha iphedi yokuqalisa kanye negesi yokuvikela ukuphepha, igesi yokulawula izinkanyezi, igumbi lokulingisa isikhala, igesi yokuhlanza amapayipi kaphethiloli wezindiza, njll.
Amafutha e-biofuel
Isibonelo: Uma usebenzisa ummbila ukukhiqiza i-ethanol, kudingeka ukuvikelwa kwe-nitrogen.
Isitoreji sezithelo nemifino
Kwezentengiselwano, indawo yokugcina izithelo nemifino elawulwayo emoyeni iye yathuthukiswa emhlabeni wonke iminyaka engaphezu kwengu-70. I-nitrogen iyindawo yokugcina izithelo nemifino ethuthukisiwe kakhulu. Izithelo nemifino zicutshungulwa emoyeni olawulwayo, okusiza ukuthuthukisa umphumela wokulondolozwa, kwandise isikhathi sazo sokuphila, futhi kuhlangabezana nazo zonke izindinganiso ezingenayo ingcoliso yokugcina okuluhlaza.
Isitoreji sokusanhlamvu
Ngesikhathi sokugcina okusanhlamvu, ukufakwa kwe-nitrogen kungavimbela okusanhlamvu ukuthi kungonakali ngenxa yethonya lamagciwane, umsebenzi wezinambuzane noma ukuphefumula kokusanhlamvu uqobo. I-nitrogen ayikwazi nje ukunciphisa okuqukethwe yi-oxygen emoyeni, ibhubhise imisebenzi yomzimba yamagciwane kanye nendawo ephilayo yezinambuzane, kodwa futhi ivimbele ukuphefumula kokusanhlamvu uqobo.
Ukusika nge-laser
I-nitrogen isetshenziselwa ukusika insimbi engagqwali nge-laser ukuvimbela ingxenye ehlanganisiwe ukuthi ingangcoliswa yi-oxygen uma ivezwa emoyeni, futhi ivimbela nezimbobo ukuthi zingabonakali ku-weld.
Ukuvikelwa kokushisela
Lapho kushiselwa izinsimbi, i-nitrogen ingasetshenziswa ukuvikela insimbi ekushisweni yi-oxidation.
Vikela izinsalela zomlando
Eminyuziyamu, amanye amakhasi okupenda ayigugu futhi angavamile avame ukugcwala i-nitrogen, okwenza kube nzima ukuthi izibungu zisinde. Ngaleyo ndlela kufezwa umphumela wokuvikela wezincwadi zasendulo.
Ukuvimbela umlilo kanye nokucisha umlilo
I-nitrogen ayinawo umphumela wokusekela ukusha, futhi inani elifanele lomjovo we-nitrogen lingadlala indima ekuvimbeleni umlilo nasekucimeni umlilo.
