5) Sistemụ mgbasa ozi alkaline
Sistemụ a gụnyere akụrụngwa isi ndị a:
Ihe nkewa hydrogen na oxygen - mgbapụta mgbasa alkali - valvụ - nzacha alkali - electrolyzer
Isi ihe dị na ya bụ: mmiri alkali agwakọtara ya na hydrogen na oxygen dị na hydrogen na oxygen kewapụrụ site na ihe nkewa gas-liquid wee laghachi na ọkpọkọ mmiri alkali. N'ebe a, ihe nkewa hydrogen na ihe nkewa oxygen jikọtara, ihe nkewa alkali mmiri alkali ga-emegharị ahụ. Mmiri alkali na-agagharị na valvụ na ihe nzacha mmiri alkali dị n'azụ. Mgbe ihe nzacha ahụ sachara ihe ndị na-adịghị mma, mmiri alkali na-agagharị na ime electrolyzer.
(6) Sistemụ hydrogen
A na-emepụta hydrogen site n'akụkụ elektrọd katode ma rute na nkewa yana sistemụ mgbasa mmiri alkali. N'ime nkewa ahụ, n'ihi na hydrogen n'onwe ya dị obere, ọ ga-ekewapụ onwe ya na mmiri alkali ma rute n'elu nke nkewa ahụ, wee gafere na pipeline maka nkewa ọzọ na oyi. Mgbe mmiri jụrụ oyi, ihe njide mmiri ahụ jidere mmiri ahụ ma ruo ihe dị ka 99%, nke na-erute sistemụ nkụcha na nhicha azụ.
Ịchụpụ mmadụ: A na-ejikarị mwepụ hydrogen eme ihe maka ịchụpụ mmadụ n'oge mmalite na mgbe a na-emechi ya, ọrụ na-adịghị mma ma ọ bụ ọdịda dị ọcha, yana mwepụta ihe kpatara ya.
(7) Sistemụ oxygen
Ụzọ maka oxygen yiri nke maka hydrogen, mana n'ime ihe nkewa dị iche.
Ịchụpụ Mmadụ: Ugbu a, a na-agwọ ọtụtụ ọrụ ikuku oxygen site na ịpụpụ mmadụ.
Ojiji: Uru ojiji nke oxygen bara uru naanị na ọrụ pụrụ iche, dịka ụfọdụ ọnọdụ ojiji nke nwere ike iji ma hydrogen ma oxygen dị ọcha nke ukwuu, dịka ndị na-emepụta eriri anya. E nwekwara ụfọdụ nnukwu ọrụ ndị echekwara oghere maka ojiji oxygen. Ọnọdụ ojiji azụ bụ mmepụta nke oxygen mmiri mmiri mgbe akpọchara ma sachaa, ma ọ bụ iji oxygen ahụike site na sistemụ mgbasa. Agbanyeghị, a kabeghị achọpụta mmezi nke ọnọdụ ojiji ndị a. Nkwenye ọzọ.
(8) sistemụ mmiri oyi
Usoro electrolysis nke mmiri bụ mmeghachi omume endothermic. Usoro mmepụta hydrogen ga-enye ike eletrik. Agbanyeghị, ike eletrik nke usoro electrolysis mmiri na-eri karịrị nnabata okpomọkụ nke mmeghachi omume electrolysis mmiri. Nke ahụ pụtara na a na-agbanwe akụkụ nke ọkụ eletrik nke electrolyzer na-eji ka ọ bụrụ okpomọkụ. Akụkụ a A na-ejikarị okpomọkụ eme ihe iji kpoo sistemụ mgbasa alkali na mbido, nke mere na okpomọkụ nke ngwọta alkali na-arị elu ruo oke okpomọkụ 90 ± 5°C nke akụrụngwa chọrọ. Ọ bụrụ na electrolyzer ahụ anọgide na-arụ ọrụ mgbe ọ ruru okpomọkụ a tụrụ aro, ọ dị mkpa iji okpomọkụ emepụtara. A na-ewepụta mmiri jụrụ oyi iji nọgide na-enwe okpomọkụ nkịtị nke mpaghara mmeghachi omume electrolysis. Okpomọkụ dị elu na mpaghara mmeghachi omume electrolysis nwere ike ibelata oriri ike, mana ọ bụrụ na okpomọkụ dị oke elu, a ga-ebibi akpụkpọ ahụ nke ụlọ electrolysis, nke ga-emebikwa ọrụ ogologo oge nke akụrụngwa ahụ.
Ngwaọrụ a chọrọ ka a nọgide na-enwe okpomọkụ ọrụ na-erughị 95°C. Na mgbakwunye, a ga-ajụkwa ma wepụ mmiri n'ime hydrogen na oxygen e mepụtara, ngwaọrụ rectifier silicon nke mmiri na-achịkwa nwekwara paịpụ mmiri oyi dị mkpa.
Ahụ ọkpọkọ nke akụrụngwa buru ibu chọkwara isonye na mmiri oyi.
(9) Sistemụ njupụta nitrogen na nhicha nitrogen
Tupu e degharịa ma rụọ ọrụ ngwaọrụ ahụ, a ga-ejupụta sistemụ ahụ na nitrogen maka nnwale ikuku na-anaghị ejide. Tupu mmalite nkịtị, a ga-ejikwa nitrogen sachapụ usoro gas nke sistemụ ahụ iji hụ na gas dị na oghere gas dị n'akụkụ abụọ nke hydrogen na oxygen dị nso na mpaghara ọkụ na mgbawa.
Mgbe emechara ngwa ahụ, sistemụ njikwa ahụ ga-ejigide nrụgide na akpaghị aka ma jidekwa ụfọdụ hydrogen na oxygen n'ime sistemụ ahụ. Ọ bụrụ na a ka na-ahụ nrụgide ahụ mgbe a gbanyere akụrụngwa ahụ, ọ dịghị mkpa ime nhicha ahụ. Agbanyeghị, ọ bụrụ na ewepụ nrụgide niile, ọ ga-adị mkpa ka a sachaa ya ọzọ. Ọrụ nhicha nitrogen.
(10) Sistemụ nkụcha hydrogen (nhọrọ)
A na-eji igwe nkụcha ihe na-akpọnwụ mmiri eme ka hydrogen nke sitere na mmiri dị nro wepụ mmiri, ma mechaa jiri ihe nzacha tube nickel sintered mee ka ọ dị nro iji nweta hydrogen kpọrọ nkụ. (Dịka ihe onye ọrụ chọrọ maka hydrogen ngwaahịa si dị, sistemụ ahụ nwere ike ịgbakwunye ngwaọrụ nhicha, nhicha ahụ na-ejikwa palladium-platinum bimetallic catalytic deoxidation).
A na-eziga hydrogen nke ngwaọrụ mmepụta hydrogen electrolysis mmiri mepụtara na ngwaọrụ nhicha hydrogen site na tankị nchekwa.
Haịdrojin na-ebu ụzọ gafere ụlọ elu deoxygenation. N'okpuru ọrụ nke ihe na-akpalite ihe, oxygen dị na haịdrojin na-emeghachi omume na haịdrojin iji mepụta mmiri.
Usoro mmeghachi omume: 2H2+O2 2H2O.
Mgbe ahụ, hydrogen na-agafe na ihe na-akpọ hydrogen condenser (nke na-eme ka gas jụọ oyi iji mee ka uzuoku mmiri dị na gas ahụ dị n'ime ya wee mepụta mmiri, mmiri ahụ a kpọchiri akpọchi na-apụkwa na sistemụ ahụ site na ihe na-anakọta mmiri) wee banye n'ụlọ elu a na-akpọ adsorption.
