Izinga lokukhiqizwa komshini we-nitrogen
1. I-Air Division Nitrogen System yoMnyango Wezimboni Zezobuchwepheshe: JB6427 / 92 Standard
Ukulawulwa kwentambo kagesi, ukufakwa: i-GB5226-96 ukuqaliswa kwePende kwenziwa ngokuya nge-JB2536-80
Ingcindezi Swing Adsorption. I-PSA ngamafuphi, ubuchwepheshe obusha bokuhlukaniswa kwegesi, inezinzuzo ezilandelayo: Ubumsulwa bomkhiqizo buphezulu. Ngokuvamile kungasebenza ekamelweni lokushisa nasekucindezelweni okuphansi, ukuvuselelwa kombhede ngaphandle kokushisa, ukonga amandla kwezomnotho. ⑶ Imishini ilula, kulula ukuyisebenzisa nokuyigcina. Ukusebenza okuqhubekayo komjikelezo kungenziwa okuzenzakalelayo ngokuphelele. Ngakho-ke, lapho lobu buchwepheshe obusha buphuma, bukhathazeka ngemboni yamazwe ahlukahlukene, bancintisana ukuthuthukisa nokucwaninga, ukuthuthuka okusheshayo, nokukhula okuvuthayo.
(Umlando wokukhiqizwa kwe-psa nitrogen)
Ngo-1960, uSkarstrom waphakamisa ilungelo lobunikazi le-PSA. Usebenzise i-sieve ye-5A zeolite yamangqamuzana njenge-adsorbent futhi wasebenzisa ithuluzi lemibhede emibili le-PSA ukwahlukanisa umoya-mpilo ocebile emoyeni. Inqubo yathuthukiswa yafakwa ekukhiqizweni kwezimboni ngawo-1960. Ngawo-1980, ukusetshenziswa kwezimboni kobuchwepheshe be-psa kwenziwa inqubekela phambili yokuqhamuka, ikakhulukazi okusetshenziswa ekuhlukanisweni kwe-oxygen ne-nitrogen, ukomiswa komoya nokuhlanzwa, ukuhlanzwa kwe-hydrogen nokunye. Phakathi kwabo, inqubekela phambili yezobuchwepheshe yokwehlukaniswa kwe-oxygen ne-nitrogen inhlanganisela yenhlayiya entsha ye-adsorbent carbon molecular kanye ne-pressure swing adsorption yokuhlukanisa i-O2 ne-N2 emoyeni, ukuze ithole i-nitrogen.
Ngokuthuthuka kokusebenza nekhwalithi yesisefo samangqamuzana, kanye nokuthuthuka okuqhubekayo kwenqubo yokucindezela kwe-adsorption, ubumsulwa nokubuyiselwa kwemikhiqizo kuyaqhubeka nokuthuthuka, okwenza ingcindezi i-adsorption ekugcwalisekeni kwesisekelo sezomnotho nezimboni.
Selokhu kwethulwe ubuchwepheshe be-PSA obuqhamuka eDalian Chemical Research Institute, iHangzhou Boxiang Gas Company izibophezele ocwaningweni, emisha nasekuthuthukiseni ubuchwepheshe be-PSA, futhi ingowokuqala ukwenza ubuchwepheshe kwezimboni eChina. Inkampani yeHangzhou Boxiang eminyakeni eminingi yemishini
Ohlelweni lokukhiqiza nokumaketha, sekusetshenziswe imishini engaphezu kuka-1000 yezinsiza kusebenza ezimbonini ezimbonini ezahlukahlukene eChina.
I-nitrogen evela kudivayisi yokwenza i-nitrogen ingena ethangini le-cg-6 le-nitrogen futhi ihlungwa ngesihlungi sothuli se-bxf-16 ukuthola i-nitrogen ehlanzekile enokuhlanzeka okungama-98% kanye nesivuno se-900Nm3 / h. Ingcindezi yokukhipha yi-≥ 0.5mpa (eguquguqukayo), indawo yamazolo asemkhathini yi-40-40 ℃, okuqukethwe uwoyela kungu-.000.001 PPM, futhi uthuli luyi-.00.01μm. Ekugcineni, i-nitrogen eqediwe ingena ethangini lokugcina i-nitrogen (elilungiselelwe ngokuya ngezidingo zomsebenzisi) futhi liyiswa endaweni yegesi yomsebenzisi.
Incazelo yezici zokulawula okuzenzakalelayo komshini wokwenza i-PSA nitrogen
Idivayisi yokwenza i-nitrogen isebenzisa i-PLC S7-200 (isilawuli se-logic esingahleleka) kusuka e-SIEMENS, Germany. Iyunithi inokusebenza okuhle okulawulekayo futhi ingakhombisa imingcele yokusebenza ehlukahlukene, isimo nezimpawu zamaphutha zomshini.
B. Ubumsulwa be-nitrogen butholakala ku-inthanethi ngesikhathi sangempela. Lapho ubumsulwa be-nitrogen obukhiqizwa yidivayisi yokwenza i-nitrogen bungaphansi kwepharamitha ebekiwe (inkomba yobumsulwa be-nitrogen edingwa yikhasimende), uhlelo luzoxwayisa futhi luthulule ngokuzenzakalela. Ngemuva kokuqaliswa kwemishini, i-valve ye-solenoid izovula i-valve ye-nitrogen bese ivala i-valve ye-nitrogen ngemuva kokuthola isignali yokulawula evela ku-nitrogen analyzer. I-nitrogen engafanele izovela ngokuzenzekelayo. Lapho ubumsulwa be-nitrogen bufinyelela kulitshe, i-valve yokukhipha iyavalwa ngokuzenzakalela futhi i-nitrogen outlet valve iyavulwa ukukhipha i-nitrogen efanelekayo. Kuyo yonke inqubo yokusetshenziswa, akukho ukusebenza okwenziwa ngesandla.
Uhlobo C, idivaysi yokwenza i-nitrogen ye-BXN nedivayisi yokuhlanzwa ifakwe isistimu yokuqothula okuzenzakalelayo, kwi-nitrogen analyzer ingasetha ubumsulwa obuhle be-nitrogen ivumela umkhawulo ophansi, lapho ubumsulwa be-nitrogen buphansi kunenani elibekiwe uhlelo lomkhawulo oluphansi umsindo ne-alamu elula, futhi vula ngokuzenzakalela i-valve yokukhipha vumela i-nitrogen engafaneleki ukuqhuma phansi, lapho ibuyela ebumsulweni obujwayelekile, ichitha i-valve ngokuzenzakalela, igesi ye-nitrogen ngokukhipha kwepayipi ejwayelekile.
D, i-valve yomoya ene-valve switch switch induku, enembile, iyisiqinisekiso sokusebenza okuthembekile kwemishini yokukhiqiza i-nitrogen.
E, i-coconut mat cylinder othomathikhi ubuchwepheshe bokucindezela, ukuze kuqinisekiswe ukusebenza kwesikhathi eside futhi okuzinzile kwemishini yegesi ye-nitrogen, setha idivaysi yengcindezi yesilinda ohlelweni, futhi ngasikhathi sinye ohlelweni lokucindezelwa lusethe amaphuzu amabili kudivayisi ye-alamu, iphuzu lokuqala ekuqapheni i-alamu i-hydroxyls eguquguqukayo, i-alamu yesibili ye-hydroxyls ukusetshenziswa kwe-sieve ye-carbon molecular standby.
F, idivaysi yokwenza i-nitrogen isebenzisa uhlelo lokulawula i-Siemens PLC S7-200 kanye nohlelo lokulawula oludidiyelwe lwesikrini, ngemishini yokuqapha, ukuphatha, ukulungisa, ukukhipha, i-alamu yamaphutha, ukuqala okukude nokuma neminye imisebenzi, ngomsebenzi wokukhombisa isikrini.
