Ọganihu nke teknụzụ mmepụta hydrogen na nyocha akụ na ụba - mmepụta hydrogen na cell alkaline electrolytic

Mmepụta hydrogen cell alkaline bụ teknụzụ mmepụta hydrogen tozuru oke. Mkpụrụ ndụ alkaline dị nchebe ma bụrụ ndị a pụrụ ịdabere na ya, na-enwe ogologo ndụ nke afọ 15, ma ejiriwo ya mee ihe n'ọtụtụ ebe azụmahịa. Na-arụ ọrụ arụmọrụ nke alkaline cell bụ n'ozuzu 42% ~ 78%. N'ime afọ ole na ole gara aga, mkpụrụ ndụ electrolytic alkaline enweela ọganihu n'akụkụ abụọ. N'otu aka ahụ, a na-emeziwanye arụmọrụ cell na-emeziwanye ma na-ebelata ụgwọ ọrụ nke metụtara oriri ọkụ eletrik. N'aka nke ọzọ, njupụta na-arụ ọrụ ugbu a na-abawanye na ego ntinye ego na-ebelata.

E gosipụtara ụkpụrụ ọrụ nke alkaline electrolyzer na foto a. Batrị ahụ nwere electrodes abụọ kewapụrụ site na diaphragm na-ekpochi ikuku. A na-emikpu mgbakọ batrị n'ime nnukwu ntinye nke alkaline mmiri mmiri electrolyte KOH (20% ruo 30%) iji bulie ionic conductivity. Enwere ike iji ngwọta NaOH na NaCl dị ka electrolytes, mana anaghị ejikarị ha eme ihe. Isi mwepu nke electrolytes bụ na ha na-emebi emebi. Igwe ahụ na-arụ ọrụ na okpomọkụ nke 65 °C ruo 100 Celsius. Cathode nke cell na-emepụta hydrogen, na OH na-esi na ya pụta - na-agafe na diaphragm na anode, ebe ọ na-ejikọta ya na-emepụta oxygen.

Mkpụrụ ndụ electrolytic alkaline dị elu dabara adaba maka mmepụta hydrogen buru ibu. Mkpụrụ ndụ alkaline electrolytic mere nke ụfọdụ ndị na-emepụta nwere ikike mmepụta hydrogen dị elu na (500 ~ 760Nm3 / h), yana oriri ike kwekọrọ na 2150 ~ 3534kW. Na omume, iji gbochie mmepụta nke ngwakọta gas na-ere ọkụ, mkpụrụ hydrogen na-ejedebe na 25% ruo 100% nke ọnụ ọgụgụ a kwadoro, njupụta kachasị ugbu a bụ ihe dịka 0.4A / cm2, okpomọkụ na-arụ ọrụ bụ 5 ruo 100 ° C. na nrụgide electrolytic kachasị dị nso 2.5 ruo 3.0 MPa. Mgbe nrụgide electrolytic dị oke elu, ego ntinye ego na-abawanye na ihe ize ndụ nke ịmepụta ngwakọta gas na-emerụ ahụ na-abawanye nke ukwuu. Na-enweghị ngwaọrụ nhicha enyemaka ọ bụla, ịdị ọcha nke hydrogen nke electrolysis cell alkaline mepụtara nwere ike iru 99%. Alkaline electrolytic cell electrolytic mmiri ga-adị ọcha, iji chebe electrode na nchekwa ọrụ, mmiri conductivity bụ ihe na-erughị 5S / cm.
