ʻO ka 'mea pale kaiapuni' kupaianaha: pehea e pale ai ka nozzle desulfurization silicon carbide i ka lani polū a me nā ao keʻokeʻo?

I ke kiʻi nui o ka hana ʻoihana, aia mau kekahi mau ʻāpana liʻiliʻi e hana mālie ana i nā misionari koʻikoʻi. ʻO ka nozzle desulfurization silicon carbide he "hero ma hope o nā hiʻohiʻona" - peʻe ia i loko o ka hale kiaʻi desulfurization o nā hale hana mana a me nā hale hana kila, i kēlā me kēia lā "hoʻomaʻemaʻe" i ke kinoea flue ʻoihana, e kāohi ana i ka sulfur dioxide ʻino ma mua o ka hoʻokuʻu ʻia ʻana. He aha ka hiʻohiʻona kūikawā o kēia mea hana pololei i hana ʻia me ka mea silicon carbide?
1, No ke aha he silicon carbide? ʻO nā 'iwi paʻakikī' i loko o ka mea
No ka hoʻomaopopo ʻana i nā pono onā nozzles desulfurization silicon carbide, pono mākou e hoʻomaka me kā lākou "kumukānāwai". ʻO ka Silicon carbide kahi mea inorganic i hana ʻia me ke ʻano hana, me nā ʻātoma i hoʻopaʻa ʻia e nā pilina covalent ikaika loa e hana i kahi ʻano paʻa e like me ke daimana. Hāʻawi kēia ʻano iā ia me ʻekolu "mana nui":
Kūpaʻa i ka palaho: Hoʻohui ʻia ke kinoea flue ʻoihana me nā mea ʻino e like me ka noe waikawa a me ka slurry limestone, a e pala koke ʻia nā nozzles metala maʻamau a piha i nā lua. ʻOi aku ka kiʻekiʻe o ke kūʻē ʻana o ka Silicon carbide i ka waikawa a me ka alkali ma mua o nā metala, a hiki ke mālama i ka kūpaʻa o ke kūkulu ʻana ma hope o ka hoʻoluʻu lōʻihi ʻana i nā wahi ʻino loa.
Hiki ke kū i nā mahana kiʻekiʻe: ʻO ka mahana o ke kinoea flue i loko o ka hale kiaʻi desulfurization e hiki pinepine i nā haneli degere Celsius, a i kekahi manawa aia paha he ʻokoʻa nui o ka mahana ma muli o ka hoʻomaka ʻana a me ka pani ʻana o nā lako. He ikaika loa ke kūpaʻa wela o ka silicon carbide, a ʻaʻole maʻalahi ke haki ʻoiai inā loaʻa koke ka hopena wela kiʻekiʻe. He hilinaʻi nō ia ma lalo o nā kūlana wela kiʻekiʻe loa.
Hiki ke kū i ka ʻaʻahu a me ka haehae: Ke hele ka slurry desulfurization kahe wikiwiki ma o ka nozzle, e hoʻopau mau ia i ka paia o loko. ʻO ka paʻakikī o ka silicon carbide ka lua o ka daimana, a hiki iā ia ke kū maʻalahi i kēia ʻano ʻaʻahu. ʻOi aku ka lōʻihi o kona ola lawelawe ma mua o nā nozzles plastik a metala maʻamau.

2, ʻAʻole wale ka 'paʻa', akā he 'hoʻoikaika' hoʻi no ka pono o ka desulfurization
ʻOi aku ka waiwai o nā nozzles desulfurization silicon carbide ma mua o ka "lōʻihi". Hūnā kona hoʻolālā i kahi mea pohihihi: ʻae nā kahawai wili kūloko i ka slurry desulfurization e hui mau a kuʻi i ke kahe, a laila atomizing i loko o nā kulu liʻiliʻi a like - ʻo ka nui o ka wahi pili ma waena o kēia mau kulu a me ke kinoea flue, ʻoi aku ka kiʻekiʻe o ka pono o ka omo ʻana o ka sulfur dioxide.
ʻOi aku ka mea nui, ʻaʻole maʻalahi ka paʻa ʻana. Hoʻohuihui ʻia nā ʻāpana liʻiliʻi i loko o nā slurries ʻoihana, a ua maʻalahi ka paʻa ʻana o nā kahawai haiki o nā nozzles maʻamau, e hopena ana i ka pīpī like ʻole a me ka hoʻemi ʻana i ka pono o ka desulfurization. He ākea ka hoʻolālā kahawai kahe o ka nozzle silicon carbide, e ʻae ana i nā ʻāpana e hele mālie, e hōʻemi nui ana i ka downtime a me ka mālama ʻana i hana ʻia e ka paʻa ʻana.
3. ʻO ke koho koʻikoʻi ma lalo o nā kulekele palekana kaiapuni
Me nā kūlana kaiapuni paʻa e piʻi nei, ua ʻoi aku ka kiʻekiʻe o nā koi o nā ʻoihana no nā lako desulfurization. No ka laʻana, ua hoʻopaʻa nui ʻia ka palena o ka sulfur dioxide i loko o ke kinoea flue i hoʻopuka ʻia e nā mea kanu mana. ʻO ke ʻano kēia, pono e ʻoi aku ka maikaʻi a me ke kūpaʻa o ka ʻōnaehana desulfurization - a ʻo ka hana o ka nozzle e pili pololei ana i ka hopena hoʻomaʻemaʻe hope loa.
ʻOiai ke kiʻekiʻe o ke kumukūʻai kūʻai mua o nā nozzles desulfurization silicon carbide ma mua o nā nozzles maʻamau, ʻoi aku ka hoʻokele waiwai o lākou i ka wā lōʻihi. ʻOi aku ka lōʻihi o kona ola lawelawe ma mua o nā nozzles plastik, hiki ke hōʻemi nui i ka pinepine o ka hoʻololi a me nā pohō downtime. No nā ʻoihana e alualu nei i ka hana hoʻomau, ʻo ke ʻano o ka "hoʻopukapuka manawa hoʻokahi, hopohopo lōʻihi" he mea waiwai nui ia.
4, ʻAʻole wale ka desulfurization, ʻike ʻia nā noi e hiki mai ana
Ma waho aʻe o ka mālama ʻana i ke kinoea flue ʻoihana, ke puka mai nei ka hiki o nā mea silicon carbide ma nā kahua hou aʻe. ʻO kona kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻana i ka radiation e hoʻokaʻawale iā ia i nā kahua kiʻekiʻe e like me ka ikehu nukelea a me ka aerospace; I ka ʻoihana ikehu hou, hoʻohana ʻia hoʻi ia i nā lako sintering wela kiʻekiʻe no nā mea pākahi lithium. 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 maoli ia ma waena o ka nohona ʻoihana a me ka palekana o ke kaiapuni. Hoʻohana ia i ke akamai o ka ʻepekema mea e hiki ai i ka hana ʻoihana ke noho pū me nā lani polū a me nā ao keʻokeʻo - ʻo ia paha ka wehewehe maikaʻi loa o ka ʻenehana e pale ana i ke kaiapuni.
