I-N₂ Buffer Tanth: Isitoreji esisebenza kahle se-nitrogen sezicelo zezimboni
Inzuzo yomkhiqizo
Amathangi okuhlinza we-nitrogen ayisakhi esibucayi kunoma yiluphi uhlelo lwe-nitrogen. Leli tampeli libhekene nokugcina ingcindezi efanele ye-nitrogen kanye nokugeleza kulo lonke uhlelo, kuqinisekise ukusebenza kwayo okuhle. Ukuqonda izici zethangi lokuhlinzwa le-nitrogen kubalulekile ekuqinisekiseni ukusebenza kahle nokusebenza kwayo.
Enye yezinto eziphambili zethangi lokuhlinzwa le-nitrogen liwubukhulu balo. Usayizi wethangi kufanele wanele ukugcina inani elifanele le-nitrogen ukuze ahlangabezane nezidingo zohlelo. Usayizi wethangi uncike ezintweni ezifana nezinga lokugeleza kanye nesikhathi sokusebenza. Ithangi lokuphakanyiswa kwe-nitrogen lincane kakhulu lingaphumela ekugcwalisekeni njalo, okuphumela ngesikhathi sokuphumula nokukhiqizwa okuncishisiwe. Ngakolunye uhlangothi, ithangi eleqiwe kungenzeka lingabizi kakhulu ngoba lisebenzisa isikhala esiningi nezinsizakusebenza.
Enye into ebalulekile yethangi lokuhlinzwa le-nitrogen ukulinganisa kwalo kwengcindezi. Amathangi kufanele aklanyelwe ukubekezelela ingcindezi ye-nitrogen egcinwe futhi isatshalaliswa. Lokhu kulinganisa kuqinisekisa ukuphepha kwethangi futhi kuvimbela noma yikuphi ukuvuza noma ukwehluleka okungaba khona. Kubalulekile ukuthintana nochwepheshe noma umenzi wokuqinisekisa ukuthi isilinganiso sethangi sethangi sihlangabezana nezidingo ezithile zohlelo lwakho lwe-nitrogen.
Izinto ezisetshenziselwa ukwakha i-nitrogen Surge Tank nazo ziyisici esibalulekile okufanele sizicabangele. Amathangi okugcina kufanele akhiwe ngezinto zokulwa nokungamelana nokugqwala ukuvikela ukusabela kwamakhemikhali noma ukonakala kusuka ekuxhumaneni ne-nitrogen. Izinto ezifana nensimbi engenasici noma insimbi yekhabhoni enezimbozo ezifanele zivame ukusetshenziswa ngenxa yokuqina kwazo nokukhulisa ukubhuka. Izinto ezikhethiwe kufanele zihambisane ne-nitrogen ukuqinisekisa ukufisa kwethangi nokusebenza.
Idizayini yethangi le-N₂ Buffer libuye libambe iqhaza elibalulekile ezimfanelweni zalo. Amathangi aklanywe kahle kufanele afake izici ezivumela ukusebenza kanye nokunakekelwa okusebenzayo. Isibonelo, amathangi okugcina kufanele abe nama-valve ama-valves afanele, ama-gauges wengcindezi kanye namadivayisi okuphepha ukuqinisekisa ukuqapha okulula nokulawula. Futhi, cabanga ukuthi ngabe ithangi lilula ukulihlola futhi liyilondoloze, ngoba lokhu kuzothinta isikhathi eside nokuthembela kwalo.
Ukufakwa okufanele nokulungiswa kubalulekile ukukhulisa izici zethangi lokuhlinza i-nitrogen. Amathangi kufanele afakwe kahle ngokuya ngemihlahlandlela yomenzi kanye namazinga wezimboni. Ukuhlolwa okujwayelekile kanye nemisebenzi yokulungisa, njengokuhlola ukuvuza, ukuqinisekisa ukusebenza kwe-valve kanye namazinga wokuhlola, kufanele kwenziwe ukukhomba noma yiziphi izinkinga noma ukuwohloka. Ngokushesha, isenzo esifanele kufanele sithathwe ukuxazulula noma yiziphi izinkinga ukuvikela ukuphazamiseka kohlelo nokugcina ukusebenza kwethangi.
Ukusebenza okuphelele kwethangi lokuphakanyiswa kwe-nitrogen kuthintwa yizimpawu zalo ezahlukahlukene, ezinqunywa ngokuyinhloko yizidingo ezithile zohlelo lwe-nitrogen. Ukuqonda okuphelele kwalezi zici kuvumela ukukhethwa kwamathangi afanele, ukufakwa, kanye nokulungiswa, okuholela ohlelweni lwe-nitrogen olusebenzayo noluthembekile.
Ngamafuphi, izici zethangi lokuphakanyiswa kwe-nitrogen, kufaka phakathi usayizi walo, ukulinganisa ingcindezi, izinto zokwakha, kanye nokwakhiwa, kuthinta kakhulu ukusebenza kwalo ohlelweni lwe-nitrogen. Ukucatshangelwa okufanele kwalezi zici kuqinisekisa ukuthi ithangi lilinganiswe ngokufanele, liyakwazi ukumelana nengcindezi, eyakhiwe ngezinto zokwakha zokugqwala, futhi inesakhiwo esiklanywe kahle. Ukufakwa kanye nokugcinwa njalo kwethangi lokugcina kubalulekile ngokulinganayo ukukhulisa ukusebenza kahle nokusebenza kwayo. Ngokuqonda nokwandisa lezi zici, amathangi okuhlinza we-nitrogen angaba nesandla empumelelweni ephelele yohlelo lwe-nitrogen.
Izicelo zomkhiqizo
Ukusetshenziswa kwamathangi we-nitrogen (N₂) Surge Tank kubalulekile ezinkambisweni zezimboni lapho ingcindezi nokulawulwa kokushisa kubaluleke kakhulu khona. Idizayinelwe ukulawula ukuguquguquka kwengcindezi futhi iqinisekise ukugeleza kwamagesi ezinzile, amathangi okuhlinza ama-nitrogen adlala indima ebalulekile ezinhlotsheni ezahlukahlukene ezitsheni ezifana namakhemikhali, ezemithi, i-petrochemical kanye nezokukhiqiza.
Umsebenzi oyinhloko wethangi lokuphakanyiswa kwe-nitrogen ukugcina i-nitrogen ezingeni elithile lokucindezela, ngokuvamile ngenhla kwengcindezi yokusebenza kohlelo. I-nitrogen egciniwe bese isetshenziselwa ukunxephezela ukunxephezela amaconsi okucindezela okungenzeka ngenxa yoshintsho ekufunweni noma ekushintsheni kwegesi. Ngokugcina ingcindezi ezinzile, amathangi we-buffer asiza ukusebenza okuqhubekayo kohlelo, ukuvimbela noma yikuphi ukuphazamiseka noma amaphutha ekukhiqizweni.
Enye yezicelo ezivelele kakhulu zamathangi wokuhlinzwa we-nitrogen ekukhiqizweni kwamakhemikhali. Kulomkhakha, ukulawula okuqondile kwengcindezi kubalulekile ekuqinisekiseni ukusabela okuphephile nokusebenza kahle kwamakhemikhali. Ukusondela amathangi ahlanganiswe nezinhlelo zokucubungula amakhemikhali zisiza ukuqinisa ukuguquguquka kwengcindezi, ngaleyo ndlela kunciphise ubungozi bezingozi nokuqinisekisa umphumela womkhiqizo ongaguquki. Ngaphezu kwalokho, amathangi okuSustge ahlinzeka ngomthombo we-nitrogen wokusebenza kokudla okuhlangene, lapho ukususwa komoya-mpilo kubalulekile ukuvikela i-oxidation noma okunye ukusabela okungafuneki.
Embonini yezemithi, amathangi okusola ama-nitrogen asetshenziselwa kakhulu ukugcina izimo zemvelo eziqondile emakamelweni ahlanzekile nasezireshini. Lawa mathangi ahlinzeka ngomthombo othembekile we-nitrogen ngezinhloso ezahlukahlukene, kufaka phakathi imishini yokuhlanza, ukuvikela ukungcoliswa nokugcina ubuqotho bomkhiqizo. Ngokuphatha ngempumelelo ingcindezi, amathangi okuhlinza we-nitrogen anikela ngokulawulwa kwekhwalithi okuphelele kanye nokuhambisana nemigomo yezezimboni, okwenza babe yimpahla ebalulekile ekukhiqizweni kwemithi.
Izitshalo ze-petrochemical zibandakanya ukuphatha inani elikhulu lezinto eziguqukayo nezivuthayo. Ngakho-ke, ukuphepha kubalulekile kulezi zindawo. Amathangi okuhlinza we-nitrogen asetshenziswa lapha njengesilinganiso sokuphepha ngokumelene nokuqhuma noma ngomlilo. Ngokugcina ingcindezi ephakeme njalo, amathangi okuthula avikela imishini yenqubo kusuka kumonakalo ongaba khona obangelwa izinguquko ezisheshayo engcindezi yesistimu.
Ngaphezu kwezimboni zamakhemikhali, ezenza imithi kanye ne-petrochemical, amathangi okuhlinza we-nitrogen asetshenziswa kabanzi ekukhiqizweni kwezinqubo ezidinga ukulawulwa kwengcindezi okuqondile, njengokukhiqizwa kwezimoto, kanye nezicelo ze-aerospace, kanye nezicelo ze-aerospace. Kulezi zimboni, amathangi okuhlinza ama-nitrogen asiza ukugcina ukucindezela okungapheli ezinhlelweni ezahlukahlukene ze-pneumatic, eqinisekisa ukusebenza okungaphazanyiswa kwemishini namathuluzi abucayi.
Lapho ukhetha ithangi lokuphakanyiswa kwe-nitrogen ukuthola uhlelo oluthile, kufanele kubhekwe izinto eziningana. Lezi zinto zifaka umthamo wethangi odingekayo, uhla lwezingcindezi kanye nezinto zokwakha. Kubalulekile ukukhetha ithangi elingahlangabezana kahle nezidingo zokugeleza nezingcindezi zohlelo, ngenkathi ucabanga futhi nezinto ezifana nokumelana nokugqwala, ukuhambisana nendawo okusebenzayo, nokulandela indawo yokusebenza, nokulandela indawo yokusebenza.
Ngamafuphi, amathangi okuhlinza we-nitrogen ayingxenye ebaluleke kakhulu ezinhlobonhlobo zezicelo zezimboni, enikeza ukuqina kwengcindezi okudingeka kakhulu ukuqinisekisa ukusebenza okuphephile futhi okusebenzayo. Amandla awo okunxephezela ukuguquguquka kwengcindezi futhi anikeze ukuhamba okuqinile kwe-nitrogen kwenza kube yimpahla ebalulekile ezimbonini lapho ukulawula khona okunembile kubalulekile. Ngokutshala imali ethangini elifanelekile le-nitrogen Surge Tank, izinkampani zingakhuphula ukusebenza kahle, zinciphise ubungozi, futhi zilondoloze ubuqotho bokwenziwa, zifaka isandla empumelelweni ephelele endaweni yanamuhla yokuncintisana yezimboni.
