I-N₂ Buffer Tank: Isitoreji Senitrojeni Esisebenzayo Sezicelo Zezimboni
Inzuzo yomkhiqizo
Amathangi okuhlinza kwe-nitrogen ayingxenye ebalulekile kunoma yiluphi uhlelo lwe-nitrogen.Leli thangi linesibopho sokugcina umfutho we-nitrogen ofanele kanye nokugeleza kulo lonke uhlelo, okuqinisekisa ukusebenza kwawo okuhle.Ukuqonda izici zethangi le-nitrogen surge kubalulekile ekuqinisekiseni ukusebenza kahle nokusebenza kahle kwalo.
Esinye sezici eziyinhloko ze-nitrogen surge tank ubukhulu balo.Usayizi wethangi kufanele wanele ukugcina inani elifanele le-nitrogen ukuhlangabezana nezidingo zesistimu.Ubukhulu bethangi buncike ezintweni ezifana nezinga lokugeleza elidingekayo kanye nobude besikhathi sokusebenza.I-nitrogen surge tank encane kakhulu ingase ibangele ukugcwaliswa njalo, okuholela ekwehleni kwesikhathi nokuncipha kokukhiqiza.Ngakolunye uhlangothi, ithangi elikhulu kakhulu lingase lingabizi kakhulu ngoba lidla isikhala esiningi nezinsiza.
Esinye isici esibalulekile sethangi le-nitrogen surge isilinganiso salo sokucindezela.Amathangi kufanele akhiwe ukuze amelane nokucindezela kwe-nitrogen egcinwayo futhi isatshalaliswa.Lesi silinganiso siqinisekisa ukuphepha kwethangi futhi sivimbela noma yikuphi ukuvuza okungaba khona noma ukwehluleka.Kubalulekile ukuthintana nochwepheshe noma umkhiqizi ukuze uqinisekise ukuthi isilinganiso somfutho wethangi sihlangabezana nezimfuneko ezithile zesistimu yakho ye-nitrogen.
Izinto ezisetshenziswayo ukwakha ithange le-nitrogen surge nazo ziyisici esibalulekile okufanele sicatshangelwe.Amathangi okugcina kufanele akhiwe ngezinto ezikwazi ukumelana nokugqwala ukuze kuvinjelwe ukusabela kwamakhemikhali okungenzeka noma ukuwohloka ekuxhumaneni ne-nitrogen.Izinto ezifana nensimbi engagqwali noma i-carbon steel enezingubo ezifanele zivame ukusetshenziswa ngenxa yokuqina kwazo nokumelana nokugqwala.Izinto ezikhethiwe kufanele zihambisane ne-nitrogen ukuze kuqinisekiswe impilo ende yethangi nokusebenza.
Ukwakhiwa kwethangi le-N₂ buffer nakho kudlala indima ebalulekile ezicini zalo.Amathangi aklanywe kahle kufanele afake izici ezivumela ukusebenza kahle nokugcinwa kahle.Isibonelo, amathangi okugcina kufanele abe namavalvu afanelekile, izikali zokucindezela umfutho kanye nemishini yokuphepha ukuze kuqinisekiswe ukuqapha nokulawula okulula.Futhi, cabanga ukuthi ithangi kulula yini ukulihlola nokuyigcina, njengoba lokhu kuzothinta isikhathi eside nokuthembeka kwalo.
Ukufakwa nokugcinwa ngendlela efanele kubalulekile ukuze kwandiswe izici zethangi lokukhuphuka kwe-nitrogen.Amathangi kufanele afakwe ngendlela efanele ngokuhambisana neziqondiso zomkhiqizi kanye namazinga emboni.Imisebenzi yokuhlola nokugcinwa njalo, njengokuhlola ukuvuza, ukuqinisekisa ukusebenza kwamavalvu nokuhlola amazinga okucindezela, kufanele kwenziwe ukuze kuhlonzwe izinkinga ezingaba khona noma ukuwohloka.Ngokushesha, isinyathelo esifanele kufanele sithathwe ukuxazulula noma yiziphi izinkinga ukuvimbela ukuphazamiseka kwesistimu nokugcina ukusebenza kahle kwethangi.
Ukusebenza kukonke kwethangi lokuhlinza kwe-nitrogen kuthintwa izici zalo ezihlukahlukene, ezinqunywa ngokuyinhloko izidingo ezithile zohlelo lwe-nitrogen.Ukuqondisisa kahle kwalezi zici kuvumela ukukhethwa kahle kwethangi, ukufakwa, nokugcinwa kahle, okuholela ohlelweni olusebenza kahle noluthembekile lwe-nitrogen.
Kafushane, izici zethangi lokuhlinza kwe-nitrogen, okuhlanganisa nosayizi walo, isilinganiso sokucindezela, izinto zokwakha, kanye nomklamo, kuthinta kakhulu ukusebenza kwalo ohlelweni lwe-nitrogen.Ukucatshangelwa kahle kwalezi zici kuqinisekisa ukuthi ithangi lilinganiswe ngokufanele, likwazi ukumelana nokucindezela, lakhiwe ngezinto ezimelana nokugqwala, futhi linesakhiwo esiklanywe kahle.Ukufakwa kanye nokugcinwa njalo kwethangi lokugcina kubalulekile ngokufanayo ukuze kwandiswe ukusebenza kahle kwalo nokusebenza kahle.Ngokuqonda kanye nokwenza kahle lezi zici, amathangi okufakwa kwe-nitrogen angaba nomthelela empumelelweni yonke yohlelo lwe-nitrogen.
Izicelo Zomkhiqizo
Ukusetshenziswa kwamathangi okuhlinzwa e-nitrogen (N₂) kubalulekile ezinqubweni zezimboni lapho ukucindezela nokulawula izinga lokushisa kubalulekile.Idizayinelwe ukulawula ukuguquguquka kwengcindezi nokuqinisekisa ukugeleza kwegesi okuzinzile, amathangi okufakwa kwe-nitrogen adlala indima ebalulekile ekusetshenzisweni okuhlukahlukene ezimbonini ezifana namakhemikhali, ezemithi, i-petrochemical kanye nezokukhiqiza.
Umsebenzi oyinhloko wethangi lokukhuphuka kwe-nitrogen ukugcina i-nitrogen ezingeni elithile lokucindezela, ngokuvamile ngaphezu kokucindezela kokusebenza kwesistimu.I-nitrogen egciniwe bese isetshenziselwa ukunxephezela ukwehla kwengcindezi okungenzeka ngenxa yezinguquko ezidingekayo noma izinguquko ekutholakaleni kwegesi.Ngokugcina ukucindezela okuzinzile, amathangi e-buffer asiza ukusebenza okuqhubekayo kwesistimu, avimbele noma yikuphi ukuphazamiseka noma amaphutha ekukhiqizeni.
Esinye sezicelo ezivelele kakhulu zamathangi okufakwa kwe-nitrogen sisekukhiqizweni kwamakhemikhali.Kule mboni, ukulawula okunembile kwengcindezi kubalulekile ukuze kuqinisekiswe ukusabela kwamakhemikhali okuphephile nokusebenza kahle.Amathangi ahlinzayo ahlanganiswe ezinhlelweni zokucubungula amakhemikhali asiza ukuzinzisa ukuguquguquka kwengcindezi, ngaleyo ndlela ehlise ubungozi bezingozi futhi aqinisekise ukukhishwa komkhiqizo okungaguquki.Ngaphezu kwalokho, amathangi okuhlinza ahlinzeka ngomthombo we-nitrogen wokusebenza kokumboza, lapho ukususwa komoya-mpilo kubalulekile ukuze kuvinjelwe i-oxidation noma okunye ukusabela okungafuneki.
Embonini yezemithi, amathangi okufakwa kwe-nitrogen asetshenziswa kabanzi ukuze kugcinwe izimo zemvelo eziqondile emakamelweni ahlanzekile namalabhorethri.Lamathangi ahlinzeka ngomthombo onokwethenjelwa we-nitrogen ngezinjongo ezihlukahlukene, okuhlanganisa izinto zokuhlanza, ukuvimbela ukungcola nokugcina ubuqotho bomkhiqizo.Ngokulawula ngempumelelo ingcindezi, amathangi okufakwa kwe-nitrogen anomthelela ekulawuleni ikhwalithi iyonke kanye nokuhambisana nemithetho yemboni, okuwenza abe yimpahla ebalulekile ekukhiqizweni kwemithi.
Izitshalo ze-Petrochemical zibandakanya ukuphatha inani elikhulu lezinto eziguquguqukayo nezivuthayo.Ngakho-ke, ukuphepha kubalulekile ezikhungweni ezinjalo.Amathangi okuhlinza kwe-nitrogen asetshenziswa lapha njengesinyathelo sokuzivikela ngokumelene nokuqhuma noma umlilo.Ngokugcina umfutho ophakeme ngokungaguquki, amathangi okuhlinzwa avikela okokusebenza kwenqubo ekulimaleni okungaba khona okubangelwa izinguquko ezingazelelwe zokucindezela kwesistimu.
Ngaphezu kwezimboni zamakhemikhali, ezemithi kanye ne-petrochemical, amathangi okuhlinzwa kwe-nitrogen asetshenziswa kakhulu ezinqubweni zokukhiqiza ezidinga ukulawulwa kwengcindezi okunembile, njengokukhiqizwa kwezimoto, ukucubungula ukudla nesiphuzo, kanye nezicelo ze-aerospace.Kulezi zimboni, amathangi okukhishwa kwe-nitrogen asiza ukugcina ingcindezi eqhubekayo ezinhlelweni ezihlukahlukene ze-pneumatic, ukuqinisekisa ukusebenza okungaphazanyiswa kwemishini namathuluzi abalulekile.
Lapho ukhetha ithangi lokuhlinza le-nitrogen lokufaka isicelo esithile, izici ezimbalwa kufanele zibhekwe.Lezi zici zihlanganisa umthamo odingekayo wethangi, ububanzi bengcindezi nezinto zokwakha.Kubalulekile ukukhetha ithangi elingahlangabezana ngokwanele nezidingo zokugeleza nengcindezi yesistimu, kuyilapho kucutshungulwa izici ezifana nokumelana nokugqwala, ukuhambisana nendawo yokusebenza, nokuthobela imithetho.
Kafushane, amathangi okufakwa kwe-nitrogen ayisici esibalulekile emisebenzini ehlukahlukene yezimboni, ehlinzeka ngokuzinza kwengcindezi edingeka kakhulu ukuze kuqinisekiswe ukusebenza okuphephile nokusebenza kahle.Ikhono layo lokunxephezela ukuguquguquka kwengcindezi nokuhlinzeka ngokugeleza okuqhubekayo kwe-nitrogen kuyenza ibe yimpahla ebalulekile ezimbonini lapho ukulawula okunembayo nokwethembeka kubalulekile.Ngokutshala ithangi elifanele le-nitrogen, izinkampani zingakhuphula ukusebenza kahle, zinciphise ubungozi, futhi zigcine ubuqotho bokukhiqiza, ekugcineni kube nesandla empumelelweni yonke endaweni yanamuhla yezimboni.
