I loko o ka ʻoihana hoʻomaʻamaʻa kinoea, ʻo ka ʻōnaehana desulfurization ke kuleana nui, a ʻo kahi mea i ʻike ʻole ʻia - ka nozzle, pili pono i ka pono a me ka paʻa o ka ʻōnaehana holoʻokoʻa. I nā makahiki i hala iho nei,nā nozzles desulfurization i hana ʻia me nā mea carbide silikaua lilo mālie i mea punahele hou o ka ʻoihana. I kēia lā, e kamaʻilio kākou e pili ana i kā lākou mau hiʻohiʻona.
He aha ka silika carbide?
ʻO ka silikoni carbide (SiC) kahi hui i haku ʻia me ka silikoni a me ke kalapona, nona ka paʻakikī kiʻekiʻe loa a me ka maikaʻi o ka wela kiʻekiʻe a me ka pale ʻana i ka corrosion. ʻO kona paʻakikī Mohs he kiʻekiʻe e like me 9.5, ka lua wale nō i ke daimana, ʻo ia hoʻi, ʻaʻole hiki ke ʻaʻahu. I ka manawa like, hiki i ka silicon carbide ke mālama i ka paʻa i nā wahi wela kiʻekiʻe ma luna o 1350 ℃, e hāʻawi iā ia i kahi pono kūlohelohe i nā kūlana hana paʻakikī.
No ke aha e koho ai i ka carbide silika e like me ka nozzle desulfurization?
Hiki ke wehewehe ʻia ke ʻano hana o nā nozzles desulfurization ma ke ʻano he "paʻakikī":
-Ka lōʻihi o ka ʻike ʻana i nā slurries corrosive acidic a alkaline
-Ka hoʻoheheʻe wai kiʻekiʻe
-ʻO nā loli wela nui
- Loaʻa paha nā ʻāpana paʻa
Hiki i nā nozzles metala kuʻuna i ka ʻino a me ka ʻaʻahu ʻana, ʻoiai ʻaʻole i kū i ka wela nā nozzles plastik. ʻO ka silicon carbide nozzle e hoʻopaʻi pololei i kēia mau hemahema, a ʻo kāna mau mea pono nui:
1. Super ikaika corrosion kū'ē
He kūpaʻa maikaʻi loa ka Silicon carbide i nā media corrosive e like me ka waikawa, ka alkali, a me ka paʻakai, a ʻoi aku kona ola lawelawe ma mua o nā nozzles metala a me ka plastic.
2. Kūleʻa maikaʻi i ka ʻaʻahu
ʻOiai inā loaʻa i ka slurry nā ʻāpana paʻa, hiki i ka silicon carbide nozzle ke mālama i ka hana hoʻoheheʻe paʻa no ka manawa lōʻihi a ʻaʻole hiki ke hoʻololi maʻalahi ʻia i ka ʻokiʻoki ʻana ma muli o ke komo ʻana.
3. ʻO ka hana kū'ē wela kiʻekiʻe
I loko o nā kaiaea kinoea wela kiʻekiʻe, ʻaʻole e hoʻoheheʻe a palupalu nā nozzles silicon carbide, e hōʻoiaʻiʻo ana i nā hopena paʻa.
4. maikaʻi thermal conductivity
Kōkua i ka nozzle e hoʻopau koke i ka wela a hoʻemi i ka pōʻino o ke koʻikoʻi wela.
ʻO ke kumu hana o ka nozzle carbide silika
Hoʻopili ka silicon carbide desulfurization nozzle i ka desulfurization slurry (maʻamau ka limestone slurry) i loko o nā kulu liʻiliʻi, e hui pū ʻia me ke kinoea flue, e hoʻoulu ai i nā mea alkaline i ka slurry me ka sulfur dioxide i loko o ke kinoea flue, pēlā e hoʻokō ai i ke kumu o ka desulfurization.
Hoʻopili pololei ka hoʻolālā a me nā mea o ka nozzle i ka hopena atomization:
-ʻO ka ʻoi aku ka maikaʻi o nā ʻāpana atomized, ʻoi aku ka nui o ka wahi pili, a ʻoi aku ka kiʻekiʻe o ka desulfurization pono
-ʻO ka mea silicon carbide e hōʻoia i ka paʻa lōʻihi o ka nozzle aperture, e pale ana i ka emi ʻana o ka hopena atomization ma muli o ka lole a me ka waimaka.
Nā hiʻohiʻona noiʻi
Hoʻohana nui ʻia nā nozzles desulfurization silicone carbide i:
-Mea mana wela
-Ke kila kila
-Ka mea kanu ʻōpala
- ʻO nā ʻoihana ʻoihana ʻē aʻe e koi ana i ka desulfurization o ke kinoea flue
Nā manaʻo mālama i kēlā me kēia lā
ʻOiai he ikaika ka lōʻihi o nā nozzles silicon carbide, he mea nui ka nānā mau a me ka mālama ʻana.
- E nānā maʻamau inā paʻa a ʻaʻahu paha ka nozzle
- E mālama i ka hana maikaʻi o ka ʻōnaehana kānana slurry
- Hoʻololi koke i ka nozzle i ka ʻike ʻana i ka emi ʻana o ka hana
hōʻuluʻulu manaʻo
ʻOiai ʻo ka silicon carbide desulfurization nozzle he mea liʻiliʻi wale nō ia i ka ʻōnaehana desulfurization, he mea nui ia i ka hoʻomaikaʻi ʻana i ka desulfurization pono a me ka hōʻemi ʻana i nā kumukūʻai hana. Ua lilo ia i koho i makemake nui ʻia no nā ʻoihana hou aʻe ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion, pale ʻana i ke kapa, a me ke kūpaʻa wela kiʻekiʻe.
ʻO ke koho ʻana i nā mea nozzle kūpono a me ka hoʻolālā ʻaʻole hiki ke hoʻomaikaʻi wale i nā hōʻailona kaiapuni, akā lawe pū kekahi i nā pono waiwai lōʻihi i ka ʻoihana. I nā koi kaiapuni i kēia mau lā, ke kiaʻi mālie nei nā nozzles desulfurization silicon carbide i ko mākou lani uliuli.
