Ma ke kiʻi nui o ka hana ʻenehana, aia mau kekahi mau mea liʻiliʻi e hana mālie ana i nā misionari koʻikoʻi. ʻO ka nozzle desulfurization silicon carbide he "ma hope o nā hiʻohiʻona hero" - peʻe ia i loko o ka hale kiaʻi desulfurization o nā mea kanu mana a me nā mea kanu kila, i kēlā me kēia lā "hoʻomaʻemaʻe" i ke kinoea flue ʻoihana, ke kāohi ʻana i ka sulfur dioxide ma mua o ka hoʻokuʻu ʻana. He aha ka hiʻohiʻona kūikawā o kēia hāmeʻa pololei i hana ʻia me nā mea carbide silika?
1, No ke aha ka silika carbide? ʻO nā 'iwi paʻakikī' i loko o ka mea
No ka hoomaopopo ana i na pomaikai onā nozzles desulfurization silika carbide, pono mākou e hoʻomaka me kā lākou "kumukanawai". ʻO ka carbide silikoni kahi mea i hoʻopaʻa ʻia me nā ʻātoma i hoʻopaʻa ʻia e nā paʻa covalent ikaika loa e hana i kahi hale paʻa e like me ke daimana. Hāʻawi kēia hale i ʻekolu "mana nui":
Kūleʻa ʻino: Ua hui pū ʻia ke kinoea hoʻoheheʻe ʻoihana me nā mea ʻino e like me ka noe waika a me ka limestone slurry, a ʻo nā nozzles metala maʻamau e ʻino koke ʻia a hoʻopuehu ʻia me nā lua. ʻOi aku ka nui o ke kūʻē ʻana o ka silikoni carbide i ka waika a me ka alkali ma mua o nā metala, a hiki ke mālama i ka kūpaʻa o ke kūkulu ʻana a hiki i ka wā lōʻihi o ka hoʻopaʻa ʻana i nā kaiapuni koʻikoʻi.
Hiki ke pale i nā wela kiʻekiʻe: ʻO ka mahana wela o ke kinoea i loko o ka hale kiaʻi desulfurization e piʻi pinepine i nā haneli degere Celsius, a i kekahi manawa aia paha nā ʻokoʻa wela nui ma muli o ka hoʻomaka ʻana a me ka pani ʻana o nā mea hana. ʻO ke kūpaʻa wela o ka silicon carbide he ikaika loa, a ʻaʻole maʻalahi ka haki ʻana a hiki i ka hopena o ka hopena wela kiʻekiʻe. Hiki ke hilinaʻi ma lalo o nā kūlana wela kiʻekiʻe loa.
Hiki ke pale i ka ʻaʻahu a me ka waimaka: Ke hele ka slurry kahe desulfurization kiʻekiʻe ma ka nozzle, e hoʻopau mau ia i ka paia o loko. ʻO ka paʻakikī o ka silicon carbide ka lua wale nō i ke daimana, a hiki iā ia ke pale maʻalahi i kēia ʻano lole. ʻOi aku ka nui o kona ola lawelawe ma mua o ka plastik maʻamau a i ʻole nā nozzles metala.
2、 ʻAʻole wale 'lōʻihi', akā he 'booster' no ka maikaʻi desulfurization
ʻOi aku ka nui o nā nozzles desulfurization silicon carbide ma mua o ka "lōʻihi". Hūnā kāna hoʻolālā i kahi mea pohihihi: ʻo nā ʻānai spiral i loko e ʻae i ka slurry desulfurization e hui mau a hui pū i ke kahe, i ka hopena o ka atomizing i loko o nā kulu maikaʻi a ʻaʻahu - ʻoi aku ka nui o ka wahi pili ma waena o kēia mau droplets a me ke kinoea puhi, ʻoi aku ka kiʻekiʻe o ka hana o ka sulfur dioxide absorption.
ʻO ka mea nui, ʻaʻole hiki ke hoʻopaʻa ʻia. Hoʻohui ʻia nā ʻāpana liʻiliʻi i loko o nā slurries ʻoihana, a ua paʻa maʻalahi nā ala haʻiki o nā nozzles maʻamau, e hopena i ka hoʻoheheʻe ʻole ʻia a hoʻemi ʻia ka maikaʻi o ka desulfurization. He ākea ka hoʻolālā kahawai kahe o ka silicon carbide nozzle, e ʻae ana i nā ʻāpana e hele mālie, e hōʻemi nui ana i ka downtime a me ka mālama ʻana ma muli o ka blockage.
3、 ʻO ka 'koho nui' ma lalo o nā kulekele palekana kaiapuni
Me nā kūlana koʻikoʻi koʻikoʻi o ke kaiapuni, loaʻa i nā ʻoihana nā koi kiʻekiʻe no nā lako desulfurization. No ka laʻana, ua hoʻopaʻa ʻia ka palena o ka sulfur dioxide i loko o ke kinoea i hoʻopuka ʻia e nā mea mana. ʻO ia ke ʻano o ka ʻōnaehana desulfurization e ʻoi aku ka maikaʻi a paʻa - a ʻo ka hana ʻana o ka nozzle pili pono i ka hopena hoʻomaʻemaʻe hope.
ʻOiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai kūʻai mua o nā nozzles desulfurization silicon carbide ma mua o nā nozzles maʻamau, ʻoi aku ka ʻoi aku o ka waiwai i ka holo lōʻihi. ʻOi aku ka lōʻihi o kona ola lawelawe ma mua o nā nozzles plastik, hiki ke hōʻemi nui i ka manawa hoʻololi a me nā poho downtime. No nā ʻoihana e ʻimi nei i ka hana hoʻomau, ʻo ke ʻano o ka "hoʻopukapuka hoʻokahi manawa, hopohopo ʻole no ka wā lōʻihi" he waiwai nui.
4、 ʻAʻole wale ka desulfurization, ʻike ʻia nā noi e hiki mai ana
Ma waho aʻe o ka hoʻomaʻamaʻa ʻana i ke kinoea flue ʻoihana, ke kū mai nei ka hiki o nā mea carbide silicon ma nā ʻāina ʻē aʻe. ʻO kona kūpaʻa wela kiʻekiʻe a me ka pale ʻana i ka radiation e kū i waho ma nā kahua kiʻekiʻe e like me ka ikehu nuklea a me ka aerospace; I loko o ka 'oihana ikehu hou, ua hoʻohana 'ia i loko o kiʻekiʻe-mehana sintering lako no ka lithium lako lako. Ma ke ʻano he nozzle desulfurization, he ʻāpana koʻikoʻi ia o ka hoʻokele kaiapuni o kēia manawa.
ʻO kēia ʻāpana liʻiliʻi i hūnā ʻia i loko o ka hale kiaʻi desulfurization he alahaka ma waena o ka moʻomeheu ʻoihana a me ka pale o ka ecological. Hoʻohana ia i ka naʻauao o ka ʻepekema waiwai e hiki ai i ka hana ʻenehana ke noho pū me ka lani uliuli a me nā ao keʻokeʻo - ʻo ia paha ka wehewehe maikaʻi loa o ka ʻenehana e pale ana i ke kaiapuni.
