Ijeneretha ye-nitrogen (ebuye ibizwe ngokuthi i-nitrogen generator) iyisisetshenziswa esisebenzisa umoya ocindezelwe njengempahla eluhlaza futhi isebenzisa i-adsorbent ebizwa nge-carbon molecular sieve ukuze ikhethe ngokukhetha i-nitrogen nomoya-mpilo ukuze ihlukanise i-nitrogen emoyeni.Ngokwezindlela ezihlukene zokuhlukanisa, kunezinhlobo ezintathu: ukuhlukaniswa komoya we-cryogenic, i-pressure swing adsorption (PSA) ukukhiqizwa kwe-nitrogen nokuhlukaniswa komoya we-membrane.
Ngokwezimiso zobuchwepheshe, ijeneretha ye-nitrogen iyithuluzi le-nitrogen eliklanywe futhi lakhiqizwa ngokusekelwe kubuchwepheshe bokukhangisa be-switch swing.Ijeneretha ye-nitrogen isebenzisa isisefo se-carbon molecular sieve (CMS) njenge-adsorbent futhi isebenzisa umgomo we-press swing adsorption (PSA) ezingeni lokushisa elivamile ukuze ihlukanise umoya ukuze ikhiqize i-nitrogen ehlanzekile kakhulu.Ngokuvamile, imibhoshongo emibili yokukhangisa ixhunywe ngokuhambisana, futhi i-PLC engenisiwe ilawula ukusebenza okuzenzakalelayo kwe-valve yomoya ephuma kwamanye amazwe ukuze kwenziwe ngokushintshana ukukhangiswa okucindezelwe kanye nokuvuselelwa kokucindezela ukuze kuqedelwe ukuhlukaniswa kwe-nitrogen ne-oxygen futhi ithole i-nitrogen ephezulu edingekayo.
Mayelana nokugeleza komsebenzi, ijeneretha ye-nitrogen icindezela umoya nge-compressor bese ingena emshinini obandayo wokomisa ukuze uhlangabezane nezidingo zamazolo zohlelo lokuphehla umfutho we-adsorption nitrogen generator emoyeni oluhlaza.Ibe isidlula ngesihlungi ukuze ikhiphe uwoyela namanzi emoyeni ongahluziwe futhi ingene ethangini lesivimba somoya ukunciphisa ukushintshashintsha kwengcindezi.Ngemva kwalokho, ukucindezela kulungiswa kungcindezi yokusebenza elinganiselwe ngokusebenzisa i-valve elawula ukucindezela futhi ithunyelwe kuma-adsorbers amabili (i-carbon molecular sieves eyakhelwe ngaphakathi), lapho umoya uhlukaniswa khona futhi kukhiqizwa i-nitrogen.Umoya oluhlaza ungena kwesinye sezikhangisi ukukhiqiza initrogen;enye i-adsorber iyancipha futhi ivuselele.Ama-adsorbers amabili asebenza ngokushintshana, ahlinzeka umoya oluhlaza ngokuqhubekayo, futhi akhiqiza i-nitrogen ngokuqhubekayo.I-nitrogen ithunyelwa ethangini le-nitrogen buffer, futhi ukucindezela kulungiswa kungcindezi elinganisiwe ngevalvu elawula ukucindezela;ibe isikalwa nge-flow meter bese ihlaziywa futhi ihlolwe nge-nitrogen analyzer.I-nitrogen efanelekile iyagodlwa futhi i-nitrogen engafanelekile ikhishwa umoya (lapho i-generator ye-nitrogen isanda kuqaliswa).
Ijeneretha ye-nitrogen ingakhiqiza i-nitrogen ngokushesha futhi kalula.Ngenxa yobuchwepheshe bayo obuphambili kanye ne-air flow distributor eyingqayizivele, ukugeleza komoya kusatshalaliswa ngokulinganayo.Isebenzisa ngokugcwele izisefo ze-carbon molecular futhi inganikeza i-nitrogen efanelekayo emizuzwini engaba ngu-20.Kulula ukuyisebenzisa, futhi imishini inesakhiwo esihlangene kanye nesakhiwo esihlanganisiwe.I-Skid-mounted, ithatha indawo encane futhi ayidingi ukutshalwa kwengqalasizinda.Utshalomali luphansi.I-nitrogen ingakhiqizwa esizeni ngokuxhuma nje amandla kagesi.Iyonga kakhulu kunezinye izindlela zokuhlinzeka nge-nitrogen.Ngoba inqubo ye-PSA iyindlela elula yokukhiqiza i-nitrogen esebenzisa umoya njengempahla eluhlaza, ingasebenzisa kuphela amandla kagesi asetshenziswa i-compressor yomoya, futhi inezinzuzo zezindleko eziphansi zokusebenza, ukusetshenziswa kwamandla okuphansi nokusebenza kahle okuphezulu.Ngokuthuthuka kobuchwepheshe bokuzenzakalela, ijeneretha ye-nitrogen ibona ukusebenza okuzenzakalelayo okusekelwe ekwakhiweni kwe-mechatronics, okungukuthi, i-PLC engenisiwe ilawula ukusebenza okuzenzakalelayo ngokugcwele, nokugeleza kwe-nitrogen, ingcindezi, nobumsulwa kuyalungiseka futhi kuboniswe ngokuqhubekayo, okuvumela ukusebenza okungagadiwe.
Embonini yezemithi, izidingo ze-nitrogen yomuthi ziphezulu kakhulu futhi zidinga ukuhlanzeka okuphezulu.Umehluko phakathi kwamajeneretha e-nitrogen okwelapha kanye nezinye izinto ze-nitrogen ukuthi indinganiso yamazwe ngamazwe ye-GMP embonini yezemithi ibeka ukuthi izingxenye ezithintana nezidakamizwa noma uketshezi kufanele zenziwe ngensimbi engagqwali kanye nezimfuneko zokuvala inzalo.Imishini idinga ukwenziwa ngensimbi engagqwali, futhi indawo yokukhipha i-nitrogen yemishini kufanele yenziwe ngensimbi engagqwali.Faka idivayisi yokuhlunga ebulala amagciwane.Futhi ngenxa yokuthi amafekthri ezenza imithi anezidingo eziphakeme zizonke zemishini, ngokuvamile anezimo.Kuyaqondakala ukuthi ngokuthuthukiswa kwamazinga e-GMP, izimboni eziningi zemishini yemithi nazo zisebenza kanzima kule ndawo, futhi amajeneretha amaningi e-nitrogen emithi ahlanzekile ahlangabezana namazinga avele emakethe.Ijeneretha ye-nitrogen yezokwelapha ehlanzekile ifanele izimboni zokudla nemithi, imijovo yamanzi, imijovo yempushana, izidakamizwa ezinkulu zokumnika, kanye nemishini yokuhambisa i-nitrogen ye-biochemical kanye neyodwa.Ikakhulukazi yakhiwe uhlelo lokucubungula umoya ocindezelweyo, uhlelo lwe-PSA lokucindezelwa kokujikajika kwe-adsorption kanye nokuhlunga ngokunemba kwegesi.Iqukethe amasistimu amathathu okuhlanganisa nesistimu yebhaktheriya.
Ngokusho kwabangaphakathi embonini, ijeneretha ye-nitrogen yezokwelapha ehlanzekile isebenzisa inqubo yakamuva yamazwe ngamazwe yokukhiqiza i-nitrogen ye-PSA, insimbi engagqwali ephucuzeke kakhulu kanye nesakhiwo esiyingqayizivele se-adsorber ukuze kuqinisekiswe ukukhiqizwa kwe-nitrogen ehlanzekile (ngaphezulu kunezidingo zamazwe ngamazwe ezingenawo umoya-mpilo), okungase Ukuhlanzeka kwe-nitrogen kufinyelela ngaphezu kwama-99.99%, kungekho mthombo wokushisa futhi kungabikho amakoloni, futhi kuhambisana nezidingo zokukhiqiza ze-GMP zemboni yezemithi yamazwe ngamazwe.Ngesikhathi esifanayo, uhlelo lokulawula okuzenzakalelayo nokuqapha luyamukelwa ukuze kutholakale ukusebenza okuzenzakalelayo kwemishini, engakwazi ukunakwa futhi isetshenziswa kabanzi embonini yezemithi.
Izisetshenziswa ezihlangabezana nezindinganiso kuphela ezingaqinisekisa ukuphepha kokukhiqizwa kwemithi.Izinkampani zemishini ekhiqiza i-nitrogen kufanele zihambisane nokuphatha ngokwethembeka futhi zisebenze kanzima ukuze zithuthukise ukusebenza kwemishini nobuchwepheshe ukuze zisebenze kangcono imboni yezokwelapha.
