Koyaya, madaidaicin waɗannan yanayin amfani har yanzu yana buƙatar ƙarin tabbaci.
8. Tsarin ruwa mai sanyaya
Tsarin electrolysis na ruwa shine halayen endothermic, kuma tsarin samar da hydrogen dole ne a samar da makamashin lantarki. Duk da haka, ƙarfin lantarki da ake cinyewa a cikin tsarin ruwa na lantarki ya zarce ka'idar ɗaukar zafi na ruwa electrolysis dauki. A wasu kalmomi, wani ɓangare na wutar lantarki da ake amfani da shi a cikin tantanin halitta na electrolysis yana canzawa zuwa zafi, wanda aka fi amfani dashi don zafi da tsarin zagayawa na alkaline a farkon, yana ƙara yawan zafin jiki na maganin alkaline zuwa yanayin zafin da ake bukata na 90 ± 5. ℃ don kayan aiki. Idan tantanin halitta na electrolysis ya ci gaba da aiki bayan isa ga zafin da aka ƙididdigewa, zafin da aka samar yana buƙatar aiwatar da shi ta hanyar sanyaya ruwa don kula da yanayin yanayin yanayin da ake buƙata na electrolysis. Matsakaicin zafin jiki a yankin amsawar electrolysis na iya rage yawan amfani da makamashi, amma idan yanayin zafi ya yi yawa, diaphragm na dakin lantarki zai lalace, wanda kuma zai yi illa ga aikin na'urar na dogon lokaci.
Ana buƙatar mafi kyawun zafin aiki don wannan na'urar don kiyaye shi a ƙasa da 95 ℃. Bugu da ƙari, hydrogen da oxygen da aka samar suma suna buƙatar sanyaya da kuma cire humided, kuma na'urar gyaran ruwa ta thyristor mai sanyaya kuma tana da bututun sanyaya.
Jikin famfo na manyan kayan aiki kuma yana buƙatar sa hannun ruwa mai sanyaya.
- Nitrogen ciko da tsarin tsabtace nitrogen
Kafin cirewa da sarrafa na'urar, yakamata a yi gwajin ƙarancin nitrogen akan tsarin. Kafin farawa na al'ada, ana kuma buƙatar tsaftace tsarin gas na tsarin tare da nitrogen don tabbatar da cewa iskar gas a cikin sararin lokaci na iskar gas a bangarorin biyu na hydrogen da oxygen yana da nisa daga kewayon flammable da fashewa.
Bayan an rufe kayan aiki, tsarin sarrafawa zai kula da matsa lamba ta atomatik kuma ya riƙe wani adadin hydrogen da oxygen a cikin tsarin. Idan har yanzu matsa lamba yana nan yayin farawa, babu buƙatar yin aikin tsarkakewa. Koyaya, idan matsa lamba ya sami sauƙi gabaɗaya, aikin tsabtace nitrogen yana buƙatar sake yin aikin.
- Tsarin bushewar hydrogen (tsarkakewa) (na zaɓi)
Iskar hydrogen da aka tanada daga ruwa na lantarki ana cire humided ta hanyar na'urar bushewa a layi daya, kuma a ƙarshe ana tsarkake ta ta hanyar tace bututun nickel mai sira don samun busasshen iskar hydrogen. Dangane da buƙatun mai amfani don samfurin hydrogen, tsarin na iya ƙara na'urar tsarkakewa, wanda ke amfani da palladium platinum bimetallic catalytic deoxygenation don tsarkakewa.
Ana aika hydrogen ɗin da ƙungiyar samar da ruwa ta ruwa electrolysis ke aika zuwa sashin tsarkakewar hydrogen ta hanyar tanki.
Da farko iskar hydrogen ya ratsa ta wani hasumiya mai kashe iskar oxygen, kuma a karkashin aikin mai kara kuzari, iskar oxygen da ke cikin iskar hydrogen tana amsawa da iskar hydrogen don samar da ruwa.
Tsarin amsawa: 2H2+O2 2H2O.
Bayan haka, iskar hydrogen ta ratsa cikin na'ura mai sanyaya hydrogen (wanda ke sanyaya iskar don sanya tururin ruwa zuwa cikin ruwa, wanda ke fitowa kai tsaye a wajen tsarin ta hanyar mai tarawa) kuma ya shiga hasumiya ta talla.
