I kēia au o ka mālama ʻana i ke kaiapuni, he mea koʻikoʻi ke kaʻina desulfurization i ka hana ʻoihana. Ma ke ʻano he mea nui, ʻo ka hana o ka nozzle desulfurization e pili pono i ka hopena desulfurization. I kēia lā, e hoʻolauna mākou i kahi nozzle desulfurization kiʻekiʻe -silika carbide ceramic desulfurization nozzle.
ʻO ka silikon carbide ceramics kahi ʻano hou o nā mea hana kiʻekiʻe, ʻoiai ʻo kona helehelena maikaʻi ʻole, loaʻa ka ikehu nui. Hoʻokumu ʻia ia i ʻelua mau mea, ke silika a me ke kalapona, a ua sintered ma o kahi kaʻina hana kūikawā. Ma ka pae microscopic, paʻa a hoʻonohonoho pono ka hoʻonohonoho atomic i loko o ka silicon carbide ceramics, e hana ana i kahi hale paʻa a paʻa, e hāʻawi iā ia i nā waiwai maikaʻi loa.
ʻO ka hiʻohiʻona koʻikoʻi o ka silicon carbide ceramic desulfurization nozzle ʻo ia kona kūpaʻa wela kiʻekiʻe. I ke kaʻina hana o ka desulfurization ʻoihana, ʻike pinepine ʻia nā wahi hana wela kiʻekiʻe, e like me ke kiʻekiʻe o ke kinoea flue i hoʻokuʻu ʻia e kekahi mau paila. Hiki i nā nozzles waiwai maʻamau ke hoʻololi a me ka pōʻino i nā wela kiʻekiʻe, e like me ka hoʻoheheʻe ʻana o ka kokoleka i nā wela kiʻekiʻe. Eia nō naʻe, hiki i ka silicon carbide ceramic desulfurization nozzle ke maʻalahi me nā mahana kiʻekiʻe a hiki i 1350 ℃, e like me ke koa wiwo ʻole, e hoʻopili ana i kā lākou pou ma ke kiʻekiʻe-mehana "kaua", hana stably, a me ka hōʻoia ʻana ʻaʻole i hoʻopilikia ʻia ke kaʻina desulfurization e ka mahana.
ʻAʻole ʻaʻahu loa ia. I loko o ke kaʻina hana desulfurization, e holoi ʻia ka nozzle e ka desulfurizer kahe wikiwiki a me nā ʻāpana paʻa i loko o ke kinoea puhi, e like me ke puhi mau ʻana o ka makani a me ke one i nā pōhaku. Hiki i ka ʻinoʻino lōʻihi ke hoʻopau i ka ʻili o ka ʻili a hoʻopōkole loa i ke ola o nā nozzles maʻamau. ʻO ka silicon carbide ceramic desulfurization nozzle, me kona paʻakikī kiʻekiʻe, hiki ke pale pono i kēia ʻano lole, hoʻonui nui i kona ola lawelawe, hōʻemi i ka mālama pono ʻana a me ka hoʻololi pinepine ʻana, a me ka mālama ʻana i nā kumukūʻai no nā ʻoihana.
ʻO ke kūpaʻa ʻino kekahi mea kaua nui no ka silicon carbide ceramic desulfurization nozzles. Loaʻa i nā desulfurizers nā waiwai corrosive e like me ka acidity a me ka alkalinity. I loko o ia ʻano kemika, ʻo nā nozzles metala maʻamau e like me nā moku palupalu e ʻohi koke ʻia e ka "corrosion wave". He kūʻē maikaʻi ka silikon carbide ceramics i kēia mau media corrosive a hiki ke mālama i ka hana paʻa a hiki i nā wahi kemika koʻikoʻi, e hoʻemi ʻole i ka pōʻino corrosion.
ʻO ke kumu hana o ka silicon carbide ceramic desulfurization nozzle he hoihoi loa. Ke komo ka desulfurizer i ka nozzle, e hoʻolalelale a hoʻololi ʻia i loko o kahi kahawai kahe kūloko i hoʻolālā ʻia, a laila e hoʻoheheʻe ʻia ma kahi kihi a me ke ʻano. Hiki iā ia ke kāpīpī i ka desulfurizer i loko o nā kulu liʻiliʻi, e like me ka ua kūlohelohe, e hoʻonui ana i ka wahi pili me ke kinoea flue, e ʻae i ka desulfurizer e hana piha me nā kinoea ʻino e like me ka sulfur dioxide i loko o ke kinoea flue, a laila e hoʻomaikaʻi ai i ka pono desulfurization.
I loko o ka hale kiaʻi desulfurization o ka mana mana, ʻo ka silicon carbide ceramic desulfurization nozzle he mea nui ia o ka papa hoʻoheheʻe. ʻO ia ke kuleana no ka hoʻoheheʻe ʻana i nā mea hana desulfurization e like me ka limestone slurry i loko o ke kinoea puhi, e hoʻoneʻe i nā mea ʻino e like me ka sulfur dioxide mai ke kinoea pahu, a me ka mālama ʻana i ko mākou lani uliuli a me nā ao keʻokeʻo. I loko o ka flue kinoea desulfurization nenoai o ka sintering machines ma kila mea kanu, ia no hoi ka mea koʻikoʻi koʻikoʻi i ka ho'ēmi pono 'ana i ka sulfur maʻiʻo i loko o ka lewa a me ka hoemi 'ana i ka pollution kaiapuni.
Me ka hoʻomau mau ʻana o nā koi o ka mālama ʻana i ke kaiapuni, ʻoi aku ka laulā o ka noi o nā silicon carbide ceramic desulfurization nozzles. I ka wā e hiki mai ana, e hoʻomau ʻia ka hoʻomaikaʻi ʻana a me ka hoʻomaikaʻi ʻana, hāʻawi hou aku i ka mālama ʻana i ka ʻoihana ʻenehana, a pale i ko mākou home kaiaola ma nā kula ʻē aʻe.
