Amaphuzu abalulekile okusebenzisa amajeneretha e-nitrogen

Amajeneretha e-nitrogenbasebenzisa umoya njengezinto zokusetshenziswa kanye nesihlungi se-carbon molecular njengesihlungi. Basebenzisa isimiso sokumuncwa kwe-pressure swing futhi basebenzisa isihlungi se-carbon molecular ukuze bamunce i-oxygen ne-nitrogen ngokukhetha ukuze bahlukanise i-nitrogen ne-oxygen. Uma kuqhathaniswa nesihlungi sendabuko Ukukhiqizwa kwe-nitrogen Izindlela, inezinzuzo zokugeleza kwenqubo elula, izinga eliphezulu lokuzenzakalela, ukukhiqizwa kwegesi okusheshayo (imizuzu eyi-16-30), ukusetshenziswa kwamandla aphansi, ubumsulwa bomkhiqizo bungalungiswa ngobubanzi ngokuya ngezidingo zomsebenzisi, ukusebenza okulula nokugcinwa, izindleko zokusebenza eziphansi, kanye nokuzivumelanisa nezimo okunamandla kwedivayisi. Ngakho-ke, incintisana kakhulu kumathuluzi angaphansi kwe-1000Nm3/h futhi ithandwa kakhulu phakathi kwabasebenzisi be-nitrogen abancane nabaphakathi. Le thuluzi seliyithuluzi elifanele abasebenzisi be-nitrogen abancane nabaphakathi.

I Ijeneretha yeNitrogen iqoqa umoya wangaphandle ethangini lokugcina igesi nge-compressor yomoya, bese ingenisa umoya ethangini lokuhlukanisa i-electrolytic ukuze ihlukanise i-nitrogen ne-oxygen esitokisini se-electrolytic. I-oxygen ikhishwa emoyeni, bese i-nitrogen ikhishwa ngemva kokuhlanzwa nokomiswa. Umphumela we-nitrogen ungalungiswa ngokuzenzakalelayo yingcindezi yesistimu. Ithuluzi lingasetshenziswa ngezikhathi ezithile noma ngokuqhubekayo, futhi ubumsulwa begesi ekhiqizwayo abuboli. Ifakwe ngamadivayisi okuvikela amazinga amaningi, iphephile, ithembekile futhi izinzile. Ithuluzi lakhiwe kakhulu uhlelo lwe-electrolysis, uhlelo lokulawula ingcindezi kanye nohlelo lokuhlanza. I-electrolysis ye-hydrogen isebenzisa ubuchwepheshe bokuhlukanisa i-membrane, futhi ingcindezi ilawulwa yidivayisi ye-photoelectric ye-infrared. Umphumela we-nitrogen ungalungiswa ngokuzenzakalelayo njengoba kudingeka ukuze kugcinwe ingcindezi izinzile.

Izinyathelo zokuqapha zokusebenzisa ama-generator e-nitrogen:

Isihlungi sokungena komoya sejeneretha ye-nitrogen sidinga ukuhlanzwa njalo. Umjikelezo uncike esimweni sothuli lwangaphakathi. Ukuhlanzwa kwe-Ultrasonic kungagcina ukungena komoya kungaphazanyiswa. Ngaphandle kwalokho, kulula ukwandisa umthwalo womsebenzi nokushisa i-compressor. Uma izinga lokushisa liphezulu kakhulu, kuzokwenzeka isivikelo sokushisa ngokweqile, okuholela ekuvalekeni.

Njengoba i-compressor yejeneretha ye-nitrogen iwumthwalo obangela ukuguquka, ugesi osheshayo ngesikhathi sokuvula nokuvala uphakeme kaningana kunangesikhathi sokusebenza okuvamile, futhi kulula ukuwuhlanganisa, ngakho-ke kufanele kukhethwe i-fuse engu-6A.

Njengoba i-compressor ehlome ngaleli thuluzi isebenza kwimodi yesekethe evulekile, uwoyela wokugcoba uzokhishwa emshinini ngamanzi, okubangela ukusetshenziswa. Ngakho-ke, ngemva konyaka owodwa wokusetshenziswa, i-compressor kufanele igcotshwe kahle, futhi imbobo yokugcwalisa uwoyela ingaba seduze nendawo yokuphuma ye-compressor noma kusukela ekungeneni komoya. Kunconywa ukwengeza amagremu angu-200 kawoyela wokuqandisa weNombolo 18.

Ukuze ugweme umswakama omningi emshinini futhi uthinte ukuhlanzeka komoya, udinga ukucindezela inkinobho yokukhipha amanzi imizuzwana embalwa ngaphambi kokuvala isikhathi ngasinye. Ipayipi lokukhipha amanzi lingaxhunywa ebhodleleni lepulasitiki ukuze kugwenywe ukuchitheka kwamanzi, futhi akufanele kube ngaphansi kwesisodwa ngosuku.

Ishubhu lokomisa lejeneretha ye-nitrogen kufanele lishintshwe njalo. Uma u-50% wejeli ye-silica eshintsha umbala eshubhu lokomisa ishintsha umbala, ukupakishwa kwangaphakathi kufanele kushintshwe. Indlela yokufaka esikhundleni: Cima ugesi bese uthulula igesi yesistimu. Khulula ishubhu lokuhlanza ngendlela ekhonjiswe umcibisholo, bese ukhulula isivalo sokugcina seshubhu lokuhlanza bese ushintsha i-desiccant yejeli ye-silica.

Uma ushintsha i-desiccant, qaphela ukufaka yonke ikotini emuncayo epayipini ukuqinisekisa ukuthi ayinawo umthelela ebusweni bokuvala, ukuze kuqinisekiswe ukuthi ingavalwa ngemva kokuba isivalo sokugcina siqinisiwe.

Ijenereyitha ye-nitrogen ayisebenzisi i-KOH ngesikhathi sokusebenza, kodwa kunconywa ukuthi ishintshwe i-electrolyte njalo ezinyangeni eziyisithupha. Uma ushintsha i-electrolyte, qala ngokususa isisombululo se-alkali esingcolile kujenereyitha ye-nitrogen, engeza amanzi acwengekile, qala ithuluzi, vumela uhlelo luhlanze uhlelo lwe-electrolysis cishe imizuzu eyi-6-10, khipha amanzi acwengekile bese uwafaka kusisombululo se-alkali esisha se-electrolytic esilungisiwe. Ukuze usebenzise ngokuqinile inqubo yokusebenza kokuqala-ukuyeka, ngemuva kokusebenzisa ijenereyitha okwesibili noma ukufaka esikhundleni se-desiccant, faka i-valve yokukhipha i-nitrogen esimweni sokukhipha amahora ama-2, bese ukhipha isibambo ngemuva kokuba umoya osepayipini lokomisa usushintshiwe ngokuphelele.

Njalo uma ucima ugesi wenjini yokukhiqiza i-nitrogen, sicela uvule i-drain valve yethangi likaphethiloli ngemuva kwejeneretha kuqala, ukhiphe umoya ethangini likaphethiloli, bese wehlisa izinga lokucindezela komoya ne-nitrogen libe ngu-0. Bese uvala i-drain valve yethangi likaphethiloli, ucindezele isibambo se-drain valve ye-nitrogen ngaphakathi, bese inqubo yokuvala isiqediwe. Ngemva kokuvala ngokwale nqubo, ngesikhathi esilandelayo lapho uqala umshini, isikhathi sokukhipha singafinyezwa sibe yimizuzu engama-30, bese ungasebenzisa i-nitrogen.
