Amanqaku aphambili okusebenzisa iijenereyitha zenitrogen

Iijenereyitha zeNitrogenBasebenzisa umoya njengezinto eziluhlaza kunye nesihluzo se-carbon molecular njenge-adsorbent. Basebenzisa umgaqo wokufunxa i-pressure swing kwaye basebenzisa isihluzo se-carbon molecular ukufunxa i-oxygen kunye ne-nitrogen ngokukhetha ukwahlula i-nitrogen kwi-oxygen. Xa kuthelekiswa ne-traditional Imveliso yeNitrogen Iindlela zayo, ineengenelo zokuhamba kwenkqubo ngokulula, inqanaba eliphezulu lokuzenzekelayo, ukuveliswa kwegesi ngokukhawuleza (imizuzu eli-16-30), ukusetyenziswa kwamandla aphantsi, ubunyulu bemveliso bunokulungiswa kuluhlu olubanzi ngokweemfuno zomsebenzisi, ukusebenza okulula nokugcinwa, iindleko zokusebenza eziphantsi, kunye nokuzivumelanisa nezimo okunamandla kwesixhobo. Ke ngoko, ikhuphisana kakhulu kwizixhobo ezingaphantsi kwe-1000Nm3/h kwaye ithandwa kakhulu phakathi kwabasebenzisi be-nitrogen abancinci nabaphakathi. Esi sixhobo sibe sisixhobo esifanelekileyo kubasebenzisi be-nitrogen abancinci nabaphakathi.

I Umvelisi weNitrogen Iqokelela umoya wangaphandle kwi-tank yokugcina igesi nge-air compressor, ize ingenise umoya kwi-tank yokwahlula i-electrolytic ukuze yahlule i-nitrogen kunye ne-oxygen kwiseli ye-electrolytic. I-oksijini ikhutshwa emoyeni, kwaye i-nitrogen ikhutshwa emva kokucocwa nokomiswa. Imveliso ye-nitrogen ingalungiswa ngokuzenzekelayo luxinzelelo lwenkqubo. Isixhobo singasetyenziswa ngamaxesha athile okanye ngokuqhubekayo, kwaye ubunyulu begesi evelisiweyo abuboli. Ixhotyiswe ngezixhobo zokukhusela ezinamanqanaba amaninzi, ikhuselekile, inokuthenjwa kwaye izinzile. Isixhobo senziwe ikakhulu yinkqubo ye-electrolysis, inkqubo yokulawula uxinzelelo kunye nenkqubo yokucoca. I-electrolysis ye-hydrogen isebenzisa iteknoloji yokwahlula i-membrane, kwaye uxinzelelo lulawulwa sisixhobo se-infrared photoelectric. Imveliso ye-nitrogen ingalungiswa ngokuzenzekelayo njengoko kufuneka ukugcina uxinzelelo luzinzile.

Amanyathelo okusebenzisa iijenereyitha zenitrogen:

Isihluzi sokungenisa umoya sejenereyitha yenitrogen kufuneka sicocwe rhoqo. Umjikelo uxhomekeke kwimeko yothuli lwangaphakathi. Ukucocwa kwe-ultrasonic kunokugcina ukungena komoya kungaphazanyiswa. Ngaphandle koko, kulula ukwandisa umthwalo womsebenzi kunye nokufudumeza i-compressor. Xa ubushushu buphezulu kakhulu, kuya kubakho ukhuseleko lobushushu obugqithisileyo, okubangela ukuvalwa.

Ekubeni i-compressor yejenereyitha ye-nitrogen ingumthwalo obangela uqhushululu, umbane okhawulezileyo ngexesha lokuvula nokucima uphezulu ngokuphindwe kaninzi kunalowo ngexesha lokusebenza okuqhelekileyo, kwaye kulula ukuwudibanisa, ngoko ke kufuneka kukhethwe i-fuse ye-6A.

Ekubeni i-compressor exhotyiswe ngesi sixhobo isebenza kwimo yesekethe evulekileyo, ioyile yokuthambisa iya kukhutshwa kumatshini ngamanzi, nto leyo ebangela ukusetyenziswa. Ke ngoko, emva konyaka omnye wokusetyenziswa, i-compressor kufuneka ithanjiswe ngokufanelekileyo, kwaye isango lokuzalisa ioyile linokuba kufutshane nendawo yokuphuma kwe-compressor okanye ukusuka kwindawo yokungena komoya. Kucetyiswa ukuba wongeze iigram ezingama-200 zeoyile yokufrijisa yeNombolo 18.

Ukuze uphephe ukufuma okugqithisileyo kumatshini kwaye uchaphazele ubunyulu bomoya, kufuneka ucinezele iswitshi yokukhupha amanzi imizuzwana embalwa ngaphambi kokuba ucime ngalo lonke ixesha. Umbhobho wokukhupha amanzi ungaqhagamshelwa kwibhotile yeplastiki ukuze ungatshizi amanzi, kwaye akufuneki ube ngaphantsi kwesihlandlo esinye ngemini.

Ityhubhu yokomisa yejenereyitha yenitrogen kufuneka itshintshwe rhoqo. Xa i-50% yejeli yesilika etshintsha umbala kwityhubhu yokomisa itshintsha umbala, kufuneka itshintshwe iphakheji yangaphakathi. Indlela yokutshintsha: Cima umbane kwaye ukhuphe igesi yenkqubo. Khulula ityhubhu yokucoca kwicala eliboniswe lutolo, emva koko ukhulule isivalo sokugqibela setyhubhu yokucoca kwaye utshintshe i-desiccant yejeli yesilika.

Xa utshintsha i-desiccant, qaphela ukufaka yonke ikotoni efunxayo kumbhobho ukuqinisekisa ukuba ayinampembelelo kumphezulu wesiphelo sokutywina, ukuze uqinisekise ukuba inokutywinwa emva kokuba isigqubuthelo sokugqibela siqinisiwe.

Ijenereyitha yenitrogen ayisebenzisi i-KOH ngexesha lokusebenza, kodwa kuyacetyiswa ukuba itshintshe i-electrolyte rhoqo kwiinyanga ezintandathu. Xa utshintsha i-electrolyte, qala ngokususa isisombululo se-alkali esimdaka kwijenereyitha yenitrogen, yongeza amanzi acocekileyo, qala isixhobo, vumela inkqubo icoce inkqubo ye-electrolysis malunga nemizuzu emi-6-10, khupha amanzi acocekileyo kwaye uwafake kwisisombululo esitsha se-electrolytic alkali esilungisiweyo. Ukuze usebenzise ngokungqongqo inkqubo yokusebenza kokuqala, emva kokusebenzisa ijenereyitha okwesibini okanye ukutshintsha i-desiccant, beka ivalvu yokukhupha i-nitrogen kwimeko yokukhupha umoya iiyure ezi-2, kwaye ukhuphe isiphatho emva kokuba umoya okwityhubhu yokomisa utshintshiwe ngokupheleleyo.

Ngalo lonke ixesha ucima umbane wenjini yejenereyitha ye-nitrogen, nceda uvule ivalvu yokukhupha amanzi yetanki yegesi engasemva kwejenereyitha kuqala, ukhuphe umoya kwitanki yegesi, kwaye unciphise uxinzelelo lomoya kunye ne-nitrogen ukuya kwi-0. Emva koko vala ivalvu yokukhupha amanzi yetanki yegesi, tyhala isiphatho sevalvu yokukhupha amanzi ye-nitrogen ngaphakathi, kwaye inkqubo yokuvala igqityiwe. Emva kokucima ngokwale nkqubo, kwixesha elizayo xa uqala umatshini, ixesha lokukhupha amanzi lingancitshiswa libe yimizuzu engama-30, kwaye ungasebenzisa i-nitrogen.
