ʻO ka nozzle desulfurization Silicon carbide: ʻāpana liʻiliʻi, hopena maikaʻi loa

I ka mālama ʻana i ke kinoea flue ʻoihana, he kuleana koʻikoʻi ka ʻōnaehana desulfurization, a hoʻokahi ʻāpana koʻikoʻi ʻole - ʻo ka nozzle, e pili pololei ana i ka pono a me ke kūpaʻa o ka ʻōnaehana holoʻokoʻa. I nā makahiki i hala iho nei,nā nozzles desulfurization i hana ʻia me ka mea silicon carbideua lilo mālie i mea punahele hou o ka ʻoihana. I kēia lā, e kamaʻilio kākou e pili ana i ko lākou mau hiʻohiʻona kūikawā.
He aha ka silicon carbide?
ʻO ka Silicon carbide (SiC) kahi hui i haku ʻia me ka silicon a me ke kalapona, nona ka paʻakikī kiʻekiʻe loa a me ke kūpaʻa kiʻekiʻe o ka mahana a me ka palaho. ʻO kona paʻakikī Mohs he 9.5, ʻo ka lua wale nō i ka daimana, ʻo ia hoʻi he kūpaʻa loa ia i ke komo ʻana. I ka manawa like, hiki i ka silicon carbide ke mālama i ke kūpaʻa i nā wahi mahana kiʻekiʻe ma luna o 1350 ℃, ka mea e hāʻawi iā ia i kahi pono kūlohelohe i nā kūlana hana paʻakikī.
No ke aha e koho ai i ka silicon carbide ma ke ʻano he nozzle desulfurization?
Hiki ke wehewehe ʻia ke ʻano hana o nā nozzles desulfurization he "ʻino":
-ʻO ka hoʻopili lōʻihi ʻana i nā slurries corrosive acidic a me alkaline
-Ka holoi wai wikiwiki
-Nā loli nui o ka mahana
-Hiki ke loaʻa nā ʻāpana paʻa

He maʻalahi nā nozzles metala kuʻuna i ka pala a me ke komo ʻana, ʻoiai ʻaʻole i kūpaʻa ka wela o nā nozzles plastik. Hoʻoponopono pololei ka nozzle silicon carbide no kēia mau hemahema, a ʻo kona mau pono nui:
1. Ke kūpaʻa ikaika loa i ka palaho
He kūpaʻa maikaʻi loa ka Silicon carbide i nā mea ʻino e like me ka waikawa, alkali, a me ka paʻakai, a ʻoi aku ka lōʻihi o kona ola lawelawe ma mua o nā nozzles metala a me ka plastik.
2. Ke kūpaʻa maikaʻi loa i ka ʻaʻahu
ʻOiai inā loaʻa i ka slurry nā ʻāpana paʻa, hiki i ka nozzle silicon carbide ke mālama i ka hana pīpī paʻa no ka manawa lōʻihi a ʻaʻole maʻalahi e loli i ke kihi pīpī ma muli o ke komo ʻana.
3. Hana kū'ē wela kiʻekiʻe
I nā wahi kinoea flue wela kiʻekiʻe, ʻaʻole e hoʻololi a palupalu paha nā nozzles silicon carbide, e hōʻoiaʻiʻo ana i nā hopena pīpī paʻa.
4. Ka hoʻokele wela maikaʻi
Kōkua i ka nozzle e hoʻopau koke i ka wela a hōʻemi i ka pōʻino o ke koʻikoʻi wela.
ʻO ke kumumanaʻo hana o ka nozzle silicon carbide
Hoʻopili ka nozzle desulfurization silicon carbide i ka slurry desulfurization (ʻo ka slurry limestone maʻamau) i loko o nā kulu liʻiliʻi, kahi e hoʻopili piha ai me ke kinoea flue, e hana ana i nā mea alkaline i loko o ka slurry e hana kemika me ka sulfur dioxide i loko o ke kinoea flue, no laila e hoʻokō ai i ke kumu o ka desulfurization.
ʻO ka hoʻolālā a me nā mea o ka nozzle e hoʻopili pololei 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 pono desulfurization
-Hōʻoia ka mea silicon carbide i ke kūpaʻa lōʻihi o ka puka nozzle, e pale ana i ka emi ʻana o ka hopena atomization ma muli o ke komo ʻana a me ka waimaka
Nā hiʻohiʻona noi
Hoʻohana nui ʻia nā nozzles desulfurization Silicon carbide i loko o:
-Kahua mana wela
-Hale hana kila
-Kahua puhi ʻōpala
-Nā ʻoihana ʻē aʻe e pono ai ka desulfurization gas flue
Nā manaʻo mālama i kēlā me kēia lā
ʻOiai he paʻa ikaika nā nozzles silicon carbide, he mea nui ka nānā mau ʻana a me ka mālama ʻana:
-E nānā pinepine inā ua paʻa a ua ʻaʻahu ʻia paha ka nozzle
-E mālama i ka hana maikaʻi o ka ʻōnaehana kānana slurry
-E hoʻololi koke i ka nozzle ke ʻike ʻia ka emi ʻana o ka hana
hōʻuluʻulu manaʻo
ʻOiai he ʻāpana liʻiliʻi wale nō ka nozzle desulfurization silicon carbide i loko o ka ʻōnaehana desulfurization, he kuleana koʻikoʻi ia i ka hoʻomaikaʻi ʻana i ka pono o ka desulfurization a me ka hōʻemi ʻana i nā kumukūʻai hana. Ua lilo ia i koho makemake ʻia no nā ʻoihana hou aʻe ma muli o kona kūpaʻa maikaʻi loa i ka corrosion, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa wela kiʻekiʻe.
ʻO ke koho ʻana i ka mea nozzle kūpono a me ka hoʻolālā ʻaʻole hiki ke hoʻomaikaʻi wale i nā ʻōkuhi kaiapuni, akā lawe mai hoʻi i nā pono waiwai lōʻihi i ka ʻoihana. I nā koi kaiapuni paʻa o kēia lā, ke kiaʻi mālie nei nā nozzles desulfurization silicon carbide i ko mākou lani polū.
