i-hydrogen kunye ne-oksijini epholileyo, kwaye amanzi aqokelelwa nge-drip trap ngaphambi kokuba athunyelwe phantsi kolawulo lwenkqubo yokulawula; I-electrolyte idlulaihydrogenkunye nezihluzi zealkali zeoksijini, i-hydrogen kunye neoksijini yealkali ezipholileyo ngokulandelelana phantsi kwentshukumo yempompo yokujikeleza, kwaye emva koko ibuyela kwiseli ye-electrolytic ukuze iqhubeke i-electrolysis.
Uxinzelelo lwenkqubo lulawulwa yinkqubo yokulawula uxinzelelo kunye nenkqubo yokulawula uxinzelelo oluhlukeneyo ukuhlangabezana neemfuno zeenkqubo ezisezantsi kunye nokugcinwa.
I-hydrogen eveliswa yi-electrolysis yamanzi ineenzuzo zokucoceka okuphezulu kunye nokungcola okuphantsi. Ngokuqhelekileyo, ukungcola kwigesi ye-hydrogen eveliswa yi-electrolysis yamanzi kuphela i-oksijini kunye namanzi, kungekho ezinye izinto (ezinokuphepha ukutyhelwa kwe-catalysts ethile). Oku kunika lula ukuvelisa igesi ye-hydrogen ecocekileyo, kwaye igesi ecocekileyo inokuhlangabezana nemigangatho yeegesi ze-electronic grade grade.
I-hydrogen eveliswa yiyunithi yemveliso ye-hydrogen idlula kwitanki yesithinteli ukuzinzisa uxinzelelo olusebenzayo lwenkqubo kwaye isuse ngakumbi amanzi asimahla kwi-hydrogen.
Emva kokungena kwisixhobo sokucoca i-hydrogen, i-hydrogen eveliswa yi-electrolysis yamanzi ihlanjululwa ngakumbi, isebenzisa imigaqo ye-catalytic reaction kunye ne-molecular sieve adsorption ukususa i-oksijini, amanzi kunye nobunye ukungcola kwi-hydrogen.
Isixhobo sinokuseta inkqubo yokulungelelanisa imveliso ye-hydrogen ngokweyona meko. Utshintsho kumthwalo wegesi luya kubangela ukuguquguquka kuxinzelelo lwetanki yokugcina i-hydrogen. Umthumeli woxinzelelo ofakwe kwitanki yokugcina uya kukhupha umqondiso we-4-20mA kwi-PLC ukuze uthelekise ixabiso leseti yokuqala, kwaye emva kokuguqulwa okuguquguqukayo kunye nokubala kwe-PID, kukhupha umqondiso we-20-4mA kwikhabhinethi yokubuyisela ukulungisa ubungakanani be i-electrolysis yangoku, ngaloo ndlela ifezekisa injongo yokulungelelaniswa ngokuzenzekelayo kwemveliso ye-hydrogen ngokotshintsho kumthwalo we-hydrogen.
Ukusabela kuphela kwinkqubo yokuveliswa kwe-hydrogen nge-electrolysis yamanzi ngamanzi (H2O), efuna ukunikezelwa ngokuqhubekayo ngamanzi akrwada ngempompo yokuzalisa amanzi. Indawo yokuzaliswa kwakhona ifumaneka kwi-hydrogen okanye i-oxygen separator. Ukongeza, i-hydrogen kunye neoksijini kufuneka ithathe umthamo omncinci wamanzi xa ishiya inkqubo. Izixhobo ezisebenzisa amanzi aphantsi zingasebenzisa i-1L/Nm ³ H2, ngelixa izixhobo ezikhulu zinokuyinciphisa ukuya kwi-0.9L/Nm ³ H2. Inkqubo ngokuqhubekayo izalisa amanzi akrwada, anokugcina uzinzo lwenqanaba lolwelo lwe-alkali kunye noxinzelelo. Iyakwazi ukuzalisa kwakhona amanzi asabelayo ngexesha elifanelekileyo ukugcina ukuxinwa kwesisombululo se-alkali.

Inkqubo ephambili yile ilandelayo: isisombululo se-alkaline esixutywe ne-hydrogen kunye ne-oksijini kwi-hydrogen oxygen separator ihlukaniswe yi-gas-liquid separator kunye ne-refluxed kwi-alkaline solution circulation pump. I-hydrogen separator kunye ne-oxygen separator zidibene apha, kwaye isisombululo se-alkaline sepompo yokujikeleza sijikeleza isisombululo se-alkaline e-refluxed kwi-valve kunye ne-alkaline isisombululo sokucoca kwi-back end. Emva kokuba isihluzo sikhuphe ukungcola okukhulu, isisombululo se-alkaline sisasazwa ngaphakathi kwiseli ye-electrolytic.
6.Inkqubo yeHydrogen
Igesi yeHydrojeni iveliswa kwicala le-electrode ye-cathode kwaye ifikelela kwisahluli kunye nenkqubo yokujikeleza kwesisombululo sealkali. Ngaphakathi kwesahluli, igesi ye-hydrogen ilula kwaye ihlukaniswe ngokwendalo kwisisombululo se-alkali, ifikelela kwindawo ephezulu yesahluli. Emva koko, idlula kwimibhobho yokwahlula ngakumbi, ipholiswe ngamanzi apholisayo, ize iqokelelwe ngesibambi se-drip ukuphumeza ubunyulu obumalunga nama-99% phambi kokufikelela kwinkqubo yokomisa nokucoca ngasemva.
Ukufuduka: Ukukhutshwa kwerhasi yehidrojeni kusetyenziswa kakhulu ngexesha lokuqalisa kunye namaxesha okuvalwa, ukusebenza okungaqhelekanga, okanye xa ukucoceka kungahambelani nemigangatho, kunye nokusombulula ingxaki.
7. Inkqubo yeoksijini
Indlela yeoksijini iyafana naleyo ye-hydrogen, ngaphandle kokuba iqhutyelwa kwizahluli ezahlukeneyo.
Ukukhupha: Okwangoku, iiprojekthi ezininzi zisebenzisa indlela yokukhupha ioksijini.
Ukusetyenziswa: Ixabiso lokusetyenziswa kwe-oksijini linentsingiselo kuphela kwiiprojekthi ezikhethekileyo, ezifana nezicelo ezinokusebenzisa zombini i-hydrogen kunye ne-oksijini ephezulu, njengabavelisi be-fiber optic. Kukwakho nezinye iiprojekthi ezinkulu ezigcine indawo yokusetyenziswa kweoksijini. Iimeko zesicelo se-backend zezokuvelisa i-oksijini yolwelo emva kokumisa kunye nokuhlanjululwa, okanye i-oksijini yonyango ngokusebenzisa iinkqubo zokusabalalisa. Nangona kunjalo, ukuchaneka kwezi meko zokusetyenziswa kusafuna ukuqinisekiswa ngakumbi.
8. Inkqubo yamanzi okupholisa
Inkqubo ye-electrolysis yamanzi yi-endothermic reaction, kwaye inkqubo yokuvelisa i-hydrogen kufuneka inikwe amandla ombane. Nangona kunjalo, amandla ombane asetyenzisiweyo kwinkqubo ye-electrolysis yamanzi adlula ubushushu bethiyori yokusabela kwe-electrolysis yamanzi. Ngamanye amazwi, inxalenye yombane esetyenziswa kwiseli ye-electrolysis iguqulwa ibe bubushushu, obusetyenziswa kakhulu ukufudumeza inkqubo yokujikeleza kwesisombululo sealkali ekuqaleni, ukunyusa ubushushu besisombululo sealkali kuluhlu olufunekayo lobushushu obuyi-90 ± 5. ℃ kwisixhobo. Ukuba iseli ye-electrolysis iyaqhubeka nokusebenza emva kokufikelela kwiqondo lokushisa elilinganisiweyo, ubushushu obuveliswayo kufuneka buqhutywe ngamanzi okupholisa ukugcina ubushushu obuqhelekileyo bendawo yokusabela kwe-electrolysis. Ukushisa okuphezulu kwindawo yokuphendula i-electrolysis kunokunciphisa ukusetyenziswa kwamandla, kodwa ukuba izinga lokushisa liphezulu kakhulu, i-diaphragm yegumbi le-electrolysis iya konakaliswa, eya kuba yingozi ekusebenzeni kwexesha elide lesixhobo.
Obona bushushu bokusebenza kwesi sixhobo bufuneka ukuba bugcinwe bungekho ngaphezulu kwama-95 ℃. Ukongeza, i-hydrogen kunye neoksijini eveliswayo nazo zifuna ukupholiswa kwaye zipheliswe, kwaye isixhobo sokulungisa i-thyristor esipholiswe ngamanzi sikwaxhotyiswe ngemibhobho yokupholisa eyimfuneko.
Umzimba wempompo wezixhobo ezinkulu nawo ufuna ukuthatha inxaxheba kwamanzi okupholisa.
- Ukuzaliswa kwe-nitrogen kunye nenkqubo yokucoca i-nitrogen
Ngaphambi kokulungiswa kunye nokusebenza kwesixhobo, uvavanyo lwe-nitrogen tightness kufuneka luqhutywe kwinkqubo. Ngaphambi kokuqaliswa okuqhelekileyo, kuyafuneka kwakhona ukucoca isigaba segesi senkqubo nge-nitrogen ukuqinisekisa ukuba igesi kwindawo yesigaba segesi kumacala omabini e-hydrogen kunye ne-oksijini ikude noluhlu olunokutsha kunye nokuqhuma.
Emva kokuba izixhobo zivaliwe, inkqubo yokulawula iya kugcina uxinzelelo kwaye igcine inani elithile le-hydrogen kunye ne-oksijini ngaphakathi kwenkqubo. Ukuba uxinzelelo lusekho ngexesha lokuqalisa, akukho mfuneko yokwenza isenzo sokucoca. Nangona kunjalo, ukuba uxinzelelo lukhululekile ngokupheleleyo, isenzo sokucoca i-nitrogen kufuneka senziwe kwakhona.
- Inkqubo yokomisa ngeHydrojeni (yokucoca) (ukhetho)
Irhasi ye-hydrogen elungiselelwe ukusuka kwi-electrolysis yamanzi ihlanjululwa ngumswakama ohambelanayo, kwaye ekugqibeleni ihlanjululwe nge-sintered nickel tube filter ukufumana igesi ye-hydrogen eyomileyo. Ngokweemfuno zomsebenzisi kwimveliso ye-hydrogen, inkqubo inokongeza isixhobo sokucoca, esebenzisa i-palladium platinum bimetallic catalytic deoxygenation yokucoca.
I-hydrogen eveliswa yiyunithi yokuvelisa i-electrolysis yamanzi i-hydrogen ithunyelwa kwiyunithi yokucoca i-hydrogen ngetanki yesithinteli.
Igesi ye-hydrogen iqala ukudlula kwinqaba ye-deoxygenation, kwaye phantsi kwesenzo se-catalyst, i-oksijini kwigesi ye-hydrogen isabela kunye negesi ye-hydrogen ukuvelisa amanzi.
Ifomula yokusabela: 2H2 + O2 2H2O.
Emva koko, irhasi yehydrogen idlula kwicondenser yehydrogen (epholisa irhasi ukuze ihlanganise umphunga wamanzi emanzini, okhutshwa ngokuzenzekelayo ngaphandle kwenkqubo ngomqokeleli) ize ingene kwinqaba ye-adsorption.
