Qoqa manje!Izinkinga ezijwayelekile kanye nokwelashwa kwamajeneretha e-nitrogen okuhlanzeka kwawo kufinyelela ezingeni (Ingxenye 2)
Njengoba sonke sazi, ukuhlanzeka kwejeneretha ye-nitrogen kubalulekile ekukhiqizeni.Ukungcola kwe-nitrogen akuthinti nje kuphela ukubonakala kwe-welding, kodwa futhi kuholela ekusetshenzisweni kwe-oxidation yomkhiqizo kanye nokukhubazeka kwenqubo, futhi kubangele ngisho nezingozi ezinkulu zokuphepha embonini yamakhemikhali neyokucima umlilo.
Isihloko esandulele esithi "Izinkinga Ezivamile Nokwelashwa Kokuhlanzeka Okungajwayelekile Kwabakhiqizi Be-nitrogen" wabelane ngobudlelwane phakathi kokungcola kwe-nitrogen kumajeneretha e-nitrogen kanye nokwehluleka kwemishini kwemishini ngokwayo kanye nezinhlelo ezisekelayo, kanye nemithelela ewumphumela nezixazululo.Kulesi sihloko, sizophinde sabelane ngezimpahla ezomile ezivela ezintweni zangaphandle: ithonya lokushisa kwendawo yokusebenza kwemishini, indawo yomoya ecindezelwe yamazolo (okuqukethwe umswakama), namafutha ayinsalela yomoya acindezelwe ekuhlanzekeni kwejeneretha ye-nitrogen nokusebenza kwemishini.

Imishini ekhiqiza i-nitrogen iklanywe kucatshangelwa indawo yokusebenza ezinzile yemishini, ngokuvamile ebangeni lika-0-45°C, okusho ukuthi okokusebenza kungakwazi ukusebenza ngokujwayelekile ngaphakathi kwaleli banga lokushisa.Ngokuphambene nalokho, uma isetshenziswa ngaphandle kwezinga lokushisa le-ambient eliklanyelwe, izoletha izinkinga ezifana nokuwohloka kokusebenza nezinga eliphezulu lokuhluleka.
Uma izinga lokushisa le-ambient lidlula u-45°C, izinga lokushisa le-exhaust le-compressor yomoya lizoba phezulu kakhulu, okuzokwandisa umthwalo kumshini wokomisa iqhwa.Ngesikhathi esifanayo, kungase kubangele umshini wokomisa iqhwa ukuthi ukhubeke ezingeni lokushisa eliphezulu.Iphuzu lamazolo lomoya ocindezelweyo alinakuqinisekiswa, okuzothinta kabi ijeneretha ye-nitrogen.umphumela.Ngaphansi kwesisekelo sokuhlanzeka okufanayo, izinga lokugeleza kokukhiqizwa kwe-nitrogen lizokwehla ngaphezu kwama-20%;uma izinga lokugeleza kokukhiqizwa kwe-nitrogen lihlala lingashintshiwe, ukuhlanzeka kwegesi ye-nitrogen ngeke kuhlangabezane nezidingo zokuklama.Ngokuhlola izinga lokushisa elabhorethri eliphezulu neliphansi, sithole ukuthi lapho izinga lokushisa lendawo lingaphansi kuka-20°C, ezinye izesekeli zikagesi azikwazi ukuqaliswa, noma isenzo asivamile, okuzobangela ngokuqondile ukuthi ijeneretha ye-nitrogen ihluleke ukuqala nokusebenza.
isisombululo
Ukuze kuthuthukiswe indawo yegumbi lekhompyutha, uhlelo lokungenisa umoya kufanele luthuthukiswe ehlobo, futhi izimo zokushisisa kufanele zengezwe ebusika ukuze kuqinisekiswe ukuthi izinga lokushisa elizungezile legumbi lekhompyutha lingaphakathi kwebanga elifanele.

Umswakamo (iphoyinti lokucindezela kwamazolo) emoyeni ocindezelweyo unomthelela oqondile kusihlungi se-nitrogen generator/carbon molecular molecular, ngakho-ke ijeneretha ye-nitrogen inezidingo eziqinile zekhwalithi yomoya ocindezelwe ngaphambili.
Isimo sangempela somthelela wokukhishwa kwamanzi kanye nomphumela wokuhlukaniswa kwamanzi wesomiso esibandayo kujeneretha we-nitrogen:
Icala 1: Umsebenzisi akazange afake i-drainer ezenzakalelayo ethangini lokugcina umoya le-compressor yomoya, futhi akazange akhiphe amanzi njalo, okubangele okuqukethwe okukhulu komswakamo emoyeni wokomisa obandayo, kanye nesihlungi sesiteji sesithathu i-air inlet kanye ne-outlet ye-dryer ebandayo ayizange ifake i-drainer Futhi i-drainage evamile eyenziwa ngesandla, okuholela ekubeni nokuqukethwe kwamanzi aphezulu kakhulu ohlelweni, okubangela isihlungi se-carbon esicushiwe esifakwe ekugcineni esingemuva ukuze simunce amanzi futhi senze amabhulokhi ukuvimba umoya ocindezelweyo. ipayipi, futhi umfutho wokuthathwa uyancishiswa (ukudla okunganele), okuholela ekubeni ubumsulwa bejeneretha ye-nitrogen bungafinyeleli izinga.Inkinga yaxazululwa ngokungeza i-drainage system ngemva kokuguqulwa.
Icala 2: Isihlukanisi samanzi sesomisi esibandayo somsebenzisi asisihle, okuholela ekutheni amanzi okupholisa angahlukaniswa ngesikhathi.Ngemuva kokuthi amanzi amaningi awuketshezi angena kujeneretha ye-nitrogen, ama-valve ama-solenoid angu-2 aphukile phakathi nesonto, futhi ingaphakathi le-valve piston yesihlalo sohlangothi lonakaliswe ngokuphelele.Amanzi awuketshezi, okwenza ukuthi i-piston seal igle, okubangele ukuthi i-valve isebenze ngendlela engavamile, futhi ijeneretha ye-nitrogen ayikwazi ukusebenza ngendlela evamile.Ngemva kokufaka indawo yokomisa okomisa, inkinga yaxazululeka.
1) Kunama-micropores ebusweni besisefo se-carbon molecular, asetshenziselwa ukukhangisa ama-molecule e-oksijini (njengoba kukhonjisiwe esithombeni).Lapho okuqukethwe kwamanzi emoyeni ocindezelwe kusinda kakhulu, ama-micropores esisefo samangqamuzana azoncipha futhi uthuli olungaphezulu kwesisefo se-molecular luzowa, okuzovimba ama-micropores esisefo futhi kubangele iyunithi isisindo se-Carbon molecular sieves. ayikwazi ukukhiqiza ukugeleza kwe-nitrogen nokuhlanzeka kwe-nitrogen edingwa isilinganiso.
Kutuswa ukuthi abasebenzisi bafake isomisi se-adsorption endaweni yokungena kwejeneretha ye-nitrogen ukuze banciphise okuqukethwe kwamanzi omoya ocindezelwe futhi baqinisekise ukuthi isisefo se-carbon molecular asingcoliswa uwoyela osindayo namanzi anzima.Ngokuvamile, impilo yesevisi ye-sieve yamangqamuzana inganwetshwa ngeminyaka engu-3-5 (ngokwezinga lokuhlanzeka).

Umthelela wokuqukethwe uwoyela emoyeni ocindezelwe kujeneretha we-nitrogen/isisefo samangqamuzana:
I-1) Kunoma yiluphi uhlobo/uhlobo lwesisefo samangqamuzana, izingxenye ezingadingekile zihlolwa ngama-micropores angaphezulu kwesisefo samangqamuzana ukuze sithole izinto esizidingayo.Kodwa zonke izisefo zamangqamuzana ziyesaba ukungcoliswa kukawoyela, futhi ukungcoliswa kukawoyela okuyinsalela kuwukungcola okungenakulungiseka ngokuphelele kuma-molecular sieve, ngakho-ke i-inlet yejeneretha ye-nitrogen inezidingo eziqinile zokuqukethwe uwoyela.
2) Njengoba kukhonjisiwe emfanekisweni ongenhla, amabala kawoyela azovala ama-micropores angaphezulu kwesisefo samangqamuzana, okubangele ukuthi ama-molecule e-oksijini angakwazi ukungena kuma-micropores futhi akhangiswe, okuholela ekwehleni kokukhiqizwa kwe-nitrogen, noma ngaphansi kwesisekelo ukuqinisekisa izinga lokugeleza langempela, ukuhlanzeka kwe-nitrogen kuzobe kungafanelekile phakathi neminyaka emi-5.
Izindlela zokuthuthukisa lezi zinkinga ezingenhla: Naka umoya wegumbi lomshini, wehlise izinga lokushisa elizungezile, futhi unciphise inani lamafutha asele emoyeni ocindezelwe;qinisa ukuvikeleka ngokusebenzisa okomisa abandayo, okomisa ukumunca, izihlungi, kanye nama-activated carbon degreaser;njalo ukufaka esikhundleni/ukugcina okokusebenza okungaphambili kwejeneretha ye-nitrogen, Ukuqinisekisa ikhwalithi yomoya ocindezelwe kungavikela kakhulu futhi kwandise impilo yesevisi yamajeneretha e-nitrogen kanye nokusebenza kwezisefo ze-carbon molecular.

Ukufingqa: izici zangaphandle ezifana nezinga lokushisa elizungezile legumbi lomshini, okuqukethwe kwamanzi kanye nowoyela ocindezelwe emoyeni kuzothinta ukusebenza kwemishini yokwenza i-nitrogen, ikakhulukazi umshini wokomisa obandayo, umshini wokomisa ukumunca kanye nesihlungi esingaphambili umshini wokwenza i-nitrogen uzothinta ngqo imishini yokwenza i-nitrogen.Umthelela wokusetshenziswa kwejeneretha ye-nitrogen, ngakho-ke ukukhethwa kwemishini yokomisa esezingeni eliphezulu futhi ephumelelayo kubaluleke kakhulu kujeneretha we-nitrogen.
Abakhiqizi abaningi be-nitrogen generator abakhiqizi imishini yokuhlanza umoya ecindezelwe ngaphambili.Uma uhlelo lokuphehla i-nitrogen lwehluleka, kulula kubakhiqizi bejeneretha ye-nitrogen kanye nabakhiqizi bokomisa ukuthi bagweme omunye nomunye futhi bangathathi isibopho komunye nomunye.
Njengomphakeli omuhle kakhulu wemikhiqizo yohlelo lomoya ocindezelweyo, i-EPS inochungechunge lomkhiqizo oluphelele, olunganikeza amakhasimende isethi ephelele yemishini efana nezomisi ezibandayo, okomisa okomisa, izihlungi, amajeneretha e-nitrogen athuthukiswe ngokuzimela futhi akhiqizwa, izinga eliphezulu lokuhlanzwa komoya Ocindezelekile. imikhiqizo ifakwe amajeneretha e-nitrogen ekhwalithi ephezulu, ukuze amakhasimende akwazi ukuthenga nokusebenzisa ngokuzethemba!
