Phantsi kwemvelaphi yesicwangciso sesizwe se-carbon dual-carbon, i-Ally Hydrogen Energy Technology Co., Ltd, esele ikhethekileyo kwimveliso ye-hydrogen iminyaka engama-25 kwaye yaba ngowokuqala ukubandakanyeka kwintsimi yamandla e-hydrogen, iqalile ukwandisa uphuhliso lobugcisa be-hydrogen eluhlaza kunye nezixhobo, kubandakanywa noyilo lweembaleki zeetanki ze-electrolysis, ukuveliswa kwezixhobo, i-electrode plating, kunye novavanyo lwetanki yokugcinwa kwe-electrolysis kunye nokusebenza.
NyeUmGaqo wokuSebenza we-Alkaline Electrolyzer
Ngokudlula i-current ngqo ngokusebenzisa i-electrolyzer egcwele i-electrolyte, iimolekyuli zamanzi zisabela nge-electrochemically kwi-electrodes kwaye ziboliswe kwi-hydrogen kunye ne-oksijini. Ukuze kuphuculwe ukuhanjiswa kwe-electrolyte, i-electrolyte ngokubanzi sisisombululo esinamanzi esine-concentration ye-30% ye-potassium hydroxide okanye i-25% ye-sodium hydroxide.
I-electrolyzer ineeseli ezininzi ze-electrolytic. Igumbi ngalinye le-electrolysis liqukethe i-cathode, i-anode, i-diaphragm kunye ne-electrolyte. Umsebenzi oyintloko we-diaphragm kukuthintela ukungena kwegesi. Kwindawo engezantsi ye-electrolyzer kukho indawo yokungena kunye ne-outlet eqhelekileyo, inxalenye ephezulu yomxube we-gas-liquid we-alkali kunye ne-oxy-alkali flow channel. Ugqithiselwe kumbane othile wangoku ngokuthe ngqo, xa umbane udlula umbane wokubola wethiyori wamanzi 1.23v kunye nombane ongathathi hlangothi we-thermal 1.48V ngaphezu kwexabiso elithile, i-electrode kunye ne-redox interface ye-redox reaction eyenzekayo, amanzi achithwa kwi-hydrogen kunye ne-oksijini.
Ezimbini Indlela i-lye ijikelezwe ngayo
1️⃣I-Hydrogen, i-Oxygen Side Lye Mixed Cycle
Kulo hlobo lokujikeleza, i-lye ingena kwipompo yokujikeleza i-lye ngokusebenzisa umbhobho wokudibanisa ezantsi kwe-hydrogen separator kunye ne-oxygen separator, kwaye ingena kwi-cathode kunye namagumbi e-anode ye-electrolyzer emva kokupholisa kunye nokucoca. Iingenelo zokujikeleza okuxubileyo zisakhiwo esilula, inkqubo emfutshane, indleko ephantsi, kwaye inokuqinisekisa ubungakanani obufanayo bokujikeleza kwe-lye kwi-cathode kunye namagumbi e-anode ye-electrolyzer; ukungalunganga kukuba kwelinye icala, kunokuchaphazela ukucoceka kwe-hydrogen kunye ne-oksijini, kwaye ngakolunye uhlangothi, kunokubangela ukuba izinga le-hydrogen-oxygen separator lingabikho kulungelelaniso, olunokubangela ukwanda komngcipheko wokuxuba i-hydrogen-oxygen. Okwangoku, icala le-hydrogen-oksijeni lomjikelezo wokuxuba i-lye yeyona nkqubo ixhaphakileyo.
2️⃣Ukwahlula ukujikeleza kwe-hydrogen kunye ne-oksijini ecaleni kwelye
Olu hlobo lokujikeleza lufuna iimpompo ezimbini zokujikeleza i-lye, okt ukujikeleza kwangaphakathi kabini. I-lye ephantsi kwe-hydrogen separator idlula kwipompo ye-hydrogen-side circulation pump, ipholile kwaye ihluzwe, kwaye ingena kwigumbi le-cathode ye-electrolyzer; I-lye esezantsi kwe-oxygen separator idlula kwipompo yokujikeleza kwe-oxygen-side, ipholile kwaye ihluzwe, kwaye ingena kwigumbi le-anode ye-electrolyzer. Inzuzo yokujikeleza okuzimeleyo kwe-lye kukuba i-hydrogen kunye ne-oksijini eveliswa yi-electrolysis inobunyulu obuphezulu, ukuphepha ngokomzimba umngcipheko wokuxuba i-hydrogen kunye ne-oxygen separator; ukungonakali kukuba ulwakhiwo kunye nenkqubo inzima kwaye iyabiza, kwaye kukwafuneka ukuba kuqinisekiswe ukuhambelana kwesantya sokuhamba, intloko, amandla kunye nezinye iiparitha zeempompo kumacala omabini, okwandisa ubunzima bokusebenza, kwaye ibeka phambili imfuno yokulawula ukuzinza kwamacala omabini enkqubo.
Iimpembelelo ezintathu zokujikeleza kwesantya se-lye kwimveliso ye-hydrogen ngamanzi e-electrolytic kunye nemeko yokusebenza ye-electrolyzer

Ikakhulu ekwandeni kwenkqubo yokujikeleza kwamanzi ancedisayo angaphakathi kunye ne-fan circulation yangaphandle kunye ne-fan, umthwalo wamanzi abandayo, njl., ukwenzela ukuba ukusetyenziswa kwamandla kwanda, ukusetyenziswa kwamandla kunyuka.
(5) Ibangela ukusilela kwesixhobo
Ukujikeleza kwe-lye ngokugqithisileyo kwandisa umthwalo kwimpompo yokujikeleza kwe-lye, ehambelana nokunyuka kwesantya sokuhamba, uxinzelelo kunye nokuguquguquka kweqondo lokushisa kwi-electrolyzer, nto leyo echaphazela i-electrodes, i-diaphragms kunye ne-gaskets ngaphakathi kwe-electrolyzer, enokuthi ibangele ukungasebenzi kakuhle kwezixhobo okanye umonakalo, kunye nokwanda komsebenzi wokugcinwa nokulungiswa.
2️⃣Ukujikeleza kweLye kuncinci kakhulu
(1) Impembelelo kubushushu betanki
Xa umthamo ojikelezayo we-lye unganelanga, ukushisa kwi-electrolyzer akukwazi ukuthathwa ngexesha, okubangelwa ukwanda kweqondo lokushisa. Imekobume yobushushu obuphezulu yenza ukunyanzeliswa komphunga wamanzi kwinqanaba lokunyuka kwegesi kunye nokunyuka kwamanzi. Ukuba amanzi akakwazi ukunyuswa ngokwaneleyo, kuya kwandisa umthwalo wenkqubo yokucoca kwaye ichaphazele umphumo wokucoca, kwaye iya kuchaphazela umphumo kunye nexesha lokuphila kwe-catalyst kunye ne-adsorbent.
(2) Impembelelo kubomi be-diaphragm
Imeko eqhubekayo yobushushu obuphezulu iya kukhawulezisa ukuguga kwe-diaphragm, yenza ukuba ukusebenza kwayo kuyancipha okanye ukugqabhuka, kulula ukubangela i-diaphragm kumacala omabini e-hydrogen kunye ne-oxygen mutual permeability, echaphazela ukucoceka kwe-hydrogen kunye ne-oksijini. Xa ukungeniswa mutual kufutshane kumda osezantsi ugqabhuko-dubulo ukuze amathuba ingozi electrolyzer kwanda kakhulu. Ngelo xesha, ukushisa okuphezulu okuqhubekayo kuya kubangela umonakalo wokuvuza kwi-gasket yokutywina, ukunciphisa ubomi bayo benkonzo.
(3) Impembelelo kwii-electrode
Ukuba inani elijikelezayo le-lye lincinci kakhulu, igesi eveliswayo ayikwazi ukushiya iziko elisebenzayo le-electrode ngokukhawuleza, kwaye ukusebenza kakuhle kwe-electrolysis kuchaphazelekayo; ukuba i-electrode ayikwazi ukudibanisa ngokupheleleyo ne-lye ukuze iqhube i-electrochemical reaction, ukukhutshwa okungaqhelekanga kunye nokutshisa okomileyo kuya kwenzeka, ukukhawuleza ukuchithwa kwe-catalyst kwi-electrode.
(4) Impembelelo kumbane weeseli
Isixa se-lye ejikelezayo sincinci kakhulu, kuba amaqamza e-hydrogen kunye neoksijini aveliswa kwiziko elisebenzayo le-electrode ayinakususwa ngexesha, kwaye isixa seegesi ezinyityilisiweyo kwi-electrolyte sanda, okubangela ukwanda kombane wegumbi elincinci kunye nokunyuka kokusetyenziswa kwamandla.
Iindlela ezine zokumisela izinga lokuhamba ngelye elona lilungileyo
Ukusombulula ezi ngxaki zingentla, kuyimfuneko ukuthatha amanyathelo ahambelanayo, njengokujonga rhoqo inkqubo yokujikeleza i-lye ukuqinisekisa ukusebenza kwayo okuqhelekileyo; ukugcina iimeko ezilungileyo zokutshatyalaliswa kobushushu malunga ne-electrolyzer; kunye nokulungelelanisa iiparitha zokusebenza ze-electrolyzer, ukuba kuyimfuneko, ukwenzela ukuphepha ukwenzeka komthamo omkhulu okanye omncinci we-lye circulation.
Elona nqanaba lokujikeleza kwe-lye kufuneka limiselwe ngokusekwe kwiiparamitha ezithile zobugcisa be-electrolyzer, njengobungakanani be-electrolyzer, inani lamagumbi, uxinzelelo lokusebenza, ubushushu bokusabela, ukuveliswa kobushushu, ukugxila kwe-lye, i-lye cooler, isahluli se-hydrogen-oxygen, ubuninzi bangoku, ukucoceka kwegesi kunye nezinye iimfuno, izixhobo kunye nokuqina kwemibhobho kunye nezinye izinto.
