Denitration hoʻohana'okikene kolu denitration enehana

Ke denitrification lapaʻau i hana ka hoʻohana 'ana i ka oxidative denitrification' ike loea hou a hana nā lātoma ('okikene kolu), e kū ai i ka pale o Nox ea puka hae. I ka Ia manawa, i nā kumumea i alakaʻi ai o ka o oxygen lehulehu, anuanu maila 'ka wai mahana, a ieoaeunoai e haawe loli i ua kālailai. Nā hualoaʻa hōʻike i ka wā o ka adsorption puʻe a me ka desorption puʻe o ka VPSA oxygen ma mīkini hana wāwahie he 40-48 kPa a me -45-55 kPa, ka oxygen ma lehulehu i hiki aku ai i ka pono ai waiwai o luna o 92%. Anuanu maila ka wai mahana e ole oi aku mamua o 32 ° C. I ka Ia manawa, ka mea, ua manaoia i ka Nox ea puka mea mau i loko o kaʻaeʻana me ka laupaʻi mana o ka Aha, e halawai me ka ieoaeunoai e haawe hoʻololi.

Me ka hoolaha ana o ka " 'ana Plan no Kāohiʻana a me Na Makuahine o ka lewa haumia ea" a me ka hou ka ho'ēmiʻana o ke ea puka o flue kinoea pollutants mai lanahu-kī pū ieoaeunoai, i ka hooponopono ana o ka naikokene'okesaside Nox i ua hoi hou. SCR mea a ianoiyuaa a heʻano o ka 'ike loea hou denitrification me ka loa ka hoʻokō wehe ka hoʻokōʻana. Naʻe, ka wā e alualu ana i ka pahu hopu o lalo, Nox ea puka, 'ike loea keia e i excessive ammonia' oihana ma muli o ka hoʻomaopop 'ana i kona hui pu iaʻi, a haoʻa pele kahua. I ka mea ia manawa, me ka hōʻeleu hoʻouka, piʻi pū, i ka huli ana uku o SO2 e SO3, piʻi pū, a me ka uahi hope loa ka hua ana o ka lehulehu o NH3 a me SO3 i loko o ke kinoea e hou aku aggravate i ka jamming o ka lewa preheater. Ke oxidative denitrification enehana ma muli i haahaa ka mahanaʻeleu nā lātoma ka loa maikai, e pale aku i ka luna pilikia. Okoa mai SCRs,ʻeleu nā lātoma (e like me O3) i keʻano o ka hanaʻana no ka synergistic lapaʻau o flue kinoea ma ka'okesaside o pollutants e like me NO, a kaumaha ke hooheheeia. Kēia kaʻina ka mea, e hana me ke 'ano o ka ieoaeunoai, i ka mea o ka lapaau, oia ka huelo kinoea o ka ieoaeunoai, ka'okesaside o NO, a kaumaha ke hooheheeia ma ka flue kinoea i kiʻekiʻe-kāki Nox a me ka mea hiki ke hooheheeia oxides, a laila, i ka ōhumu o pollutants e like me Nox, SO2, a kaumaha ke hooheheeia. Wehe i.

Ma keia pepa,ʻeleu oxidative denitration enehana Ua hoʻohana 'ia no ka noiʻi i ka Nox ea puka hooponopono i ka lanahu-ki flue kinoea, a me nā kumumea ka hoohuoi ana denitration ka hoʻokōʻana e like me o oxygen lehulehu, anuanu maila ka wai mahana, a ieoaeunoai e haawe loli i ua kālailai.

1, hoʻoikaika 'ana i ka polokalamu

Ka mua ieoaeunoai o ka mana o na mea kanu o 2 e puhi ia o ka 35t / h, a 1 'ia paha o ka 50t / h kaula e'a'ā ana. Ka mua pulu desulfurization'ōnaehana hoʻohana i ka lākou o ka limestone gypsum hana no SO2 hoopau. Kaʻeleu hakakino oxidative denitration enehana ua pili i ka huelo flue ma hope o ka flue kinoea confluence. No laila, wale ka flue kinoea kahe ana a me ka naikokene'okesaside maʻiʻo o ka huelo flue Pono e e noonoo, i mea kuokoa ka'ā pololei o ka ieoaeunoai o. E ho ohana i ka palapala desulfurization ipu, wale ka mua flue kinoea desulfurization hale kiai muliwai flue i Hoʻololi 'a Ua hoʻouka kekahi kaʻeleu hakakino mīkini'ātoma. Ke koena o ka loli 'i hou maalea i hoikeia ma ke Kii 1. o oxygen'ōnaehana,ʻeleu hakakino nenoaiu, anuanu maila ka wai'ōnaehana a me ka uila a me ka mea hana ka pāʻana kākoʻo nenoai. Ka oxygen ma'ōnaehana hoʻohana i adsorbent e kaawale o oxygen, a naikokene i loko o ka lewa ma ka adsorption a me ka desorption e paka i ka lehulehu maluna o ka oxygen. Ma hope o pressurization, deoiling, a me ka lepo ana, i ka i oxygen komo i ka hana hakakino mīkini hana wāwahie, a me ka hope ua ua loaʻa i kaʻeleu lātoma (O3) ma hapa hookuuia ma ke keena hookuuia. Ka hookuuia o kiʻekiʻe-anakahi uila uila i ka oxygen ma loko o ke keʻena hookuuia paha ke he nui ka nui o ka wela, no laila, mawaho anuanu maila 'ka wai ua koi' ia e hoʻa'ā i-hana i ka hookuuia keʻena, e hoomahuahua i ka lehulehu o kaʻeleu lātoma (O3).
