I loko o nā ʻōnaehana desulfurization ʻenehana flue, ʻoiai he liʻiliʻi ka nozzle, he kuleana koʻikoʻi ia - hoʻoholo pololei ia i ka pono desulfurization a me ka paʻa o ka hana. I mua o nā kūlana hana koʻikoʻi e like me ke kiʻekiʻe o ka wela, ka corrosion, a me ka ʻaʻahu, lilo ke koho ʻana i mea koʻikoʻi.ʻO nā seramika silikoni, me kā lākou "mana paʻakikī", ke lilo nei i mea hoʻonā i makemake ʻia i ke kahua o nā nozzles desulfurization.
1、 'Oi pale pale' kūlohelohe maoli.
ʻO ka media acidic a me ka alkaline i loko o ke kaiapuni desulfurization ua like ia me "nā lau ʻike ʻole", a ʻaʻole hiki i nā mea metala maʻamau ke pakele i nā poho ʻino. ʻO ka inertness kemika o ka silicon carbide ceramics e hāʻawi iā ia me ka pale ʻana i ka corrosion ikaika, a hiki ke noho paʻa i loko o nā wahi waikawa ikaika, e like me ke kau ʻana i kahi papa o ka pale pale ma kahi nozzle. ʻAʻole kēia hiʻohiʻona e hoʻolōʻihi i ke ola o ka nozzle, akā pale pū nō hoʻi i ka hopena o ka leaka wai desulfurization ma muli o ka corrosion.
2、 Ka 'ʻaoʻao mālie' ma lalo o ka wela kiʻekiʻe
Ke piʻi mau ka mahana i loko o ka hale kiaʻi desulfurization, nui nā mea e palupalu a deform. Eia nō naʻe, hiki i ka silicon carbide ceramics ke hoʻomau i ko lākou ʻano kumu ma kahi wela kiʻekiʻe o 1350 ℃, me kahi koena hoʻonui wela he 1/4 wale nō o nā metala. ʻO ke kūpaʻa wela kiʻekiʻe e hiki ai i ka nozzle ke hoʻokō me ka haʻalulu wela me ka maʻalahi. ʻO kēia hiʻohiʻona o ka 'ʻaʻole panicking i ka wā e ʻike ai i ka wela' e hōʻoia i ka hana mau a paʻa o ka ʻōnaehana desulfurization.
3、 ʻO ka 'holo holo kaʻa lōʻihi' i ke ao kūʻokoʻa
ʻO ka slurry kahe desulfurization kiʻekiʻe e holoi mau i ka paia o loko o ka nozzle e like me ke one. ʻO ka paʻakikī o ka silicon carbide ceramics ka lua wale nō ma mua o ke daimana, a ʻoi aku ka nui o kona pale ʻana i ka ʻaʻahu ma mua o ka hao chromium kiʻekiʻe. ʻO kēia 'ikaika paʻakikī' ikaika e hiki ai i ka nozzle ke mālama pololei i ka ʻokiʻoki a me ka hopena atomization i ka wā lōʻihi o ka hoʻoheheʻe ʻana, e pale ana i ka emi ʻana o ka hana desulfurization ma muli o ka ʻaʻahu a me ka waimaka.
4、 ʻO ka 'mea hoʻolaha ʻike ʻole' o ka mālama ʻana i ka ikehu a me ka mālama ʻana i ke kaiapuni
Mahalo i ke kiʻekiʻe kiʻekiʻe o ka mea ponoʻī, hiki i nā silicon carbide ceramic nozzles ke hoʻokō i kahi hopena atomization ʻoi aku ka lōʻihi, e hoʻomaikaʻi ana i ka hopena hopena ma waena o ka limestone slurry a me ka flue gas. ʻO kēia "ʻelua o ka hopena me ka hapalua o ka hoʻoikaika" ʻaʻole e hōʻemi wale i ka hoʻohana ʻana i nā desulfurizers, akā e hōʻemi hoʻi i ka hoʻohana ʻana i ka ikehu ʻōnaehana, hāʻawi i ke kōkua nui no ka hoʻololi ʻōmaʻomaʻo o nā ʻoihana.
Ma lalo o ka hoʻolaha ʻana i ka pahuhopu "kapona ʻelua", ʻoi aku ka waiwai o ka hilinaʻi a me ka lōʻihi o ka pono o nā lako pale kaiapuni. Hāʻawi ka silicon carbide ceramic desulfurization nozzle i kahi "hoʻokahi hana, holo lōʻihi" ka hopena no ka hoʻomaʻamaʻa ʻana i ke kinoea flue ʻenehana ma o ka hana hou ʻana, me ke ola lawelawe ʻoi aku ka paʻa o ka hana. ʻO kēia holomua ʻenehana o ka "lanakila me nā mea waiwai" e wehewehe hou ana i ke kūlana waiwai o nā ʻōnaehana desulfurization - ʻo ke koho ʻana i nā mea kūpono ʻo ia ka hoʻopukapuka kūpono.
Ma ke ʻano he hui i hoʻolaʻa ʻia i ka noiʻi a me ka hoʻomohala ʻana i nā ceramics silicon carbide, ua kūpaʻa mākou i ka hāʻawi ʻana i nā lako pale kaiapuni me ka "vitality" ikaika ma o ka ʻenehana waiwai. E hana i ka hana paʻa o kēlā me kēia nozzle i pōhaku kihi hilinaʻi i ke kaua e pale i ka lani uliuli.
