ʻO ka hoʻohana ʻana i ka anticorrosion o ka rotary kiln
ʻO Rotary kiln ka mea nui loa i ka laina hana sima, a ʻo kāna hana paʻa e pili pono ana i ka hoʻopuka a me ka maikaʻi o ka clinker sima.Eia nō naʻe, i nā makahiki i hala iho nei, ua loaʻa pinepine nā pilikia me ka pūpū kiln rotary, e like me ka deformation, nā māwae, a me nā haʻihaʻi, e hopena i nā poho pololei a me ka ʻole, a me nā pilikia palekana.Nui nā kumu o kēia mau pilikia, e like melawelaweka manawa, ka wā, ka hana o ka mea hoʻohana, a me nā mea ʻē aʻe. ʻO kekahi o nā mea koʻikoʻi ʻo ka corrosion o ka rotary kiln cylinder, e hoʻoemi i ka cylinder a hoʻemi i ka hiki ke lawe, e hopena i nā pilikia i ʻōlelo ʻia ma luna.
IMa waho aʻe o ka wela kiʻekiʻe, e hana ʻia kekahi mau kinoea corrosivein ka hana o ka calcinhanaclinker i loko o ka rotary kiln, ʻoi aku hoʻi i ka laina hana o ka hoʻoheheʻe hui ʻana, e hana ʻia ka nui o nā kinoea ʻino e like me ka sulfur oxides, nitrogen oxides, hydroxides, chlorine, etc..Hoʻopili kemika kēia mau kinoea me ka wai e hana ai i nā mea ʻakika-paʻa ʻino loa, kahi e hōʻino nui ai i ka paia o loko o ke kiln rotary.Wahi a ka ʻenekinia o kahi mea kanu sima, ua ʻino ka paia o loko o ka hui rotary kiln e 1 mm i ka hapalua makahiki.Inā ʻaʻole i hana ʻia nā hana anti-corrosion, hiki i kahi kiln rotary hou ke pilikia i nā pilikia ma hope o ka ʻumi makahiki o ka hoʻohana ʻana.
Hiki i ka anti-corrosion o ka paia o loko o ka rotary kiln ke hoʻohana i ka SY-kiʻekiʻe kiʻekiʻe e hoʻohana i ka pale anti-corrosion.ʻO nā hiʻohiʻona o kēia huahana penei:
1. ʻO ka uhiʻana he paʻakikī, paʻakikī kiʻekiʻe, kū'ē i kaʻaʻahu a me ka hopena, a kū'ē i ka erosion e ka uahi a me ka lepo lepo;
2. ʻO ka uhi ʻana he resistant i ke kiʻekiʻe wela waena corrosion e like me ka sulfide, nitrogen oxide, HCl kinoea a me ka paʻakai epa, kū'ē i ka "dew point" corrosion o ka wai condensate, a ku e alternating waikawa a me ka alkali corrosion i ke kaʻina hana o ka desulfurization a me ka denitrification;
3. He lōʻihi ke ola o ka hana a me ka paʻa maikaʻi, a ua maʻalahi ka hoʻoponoponoʻana i ka uhiʻino;
4. ʻO ka helu kiʻekiʻe o ka hoʻonui laina, ka hoʻopili maikaʻi ʻana, a me ka ikaika hoʻopaʻa ikaika me ka substrate;
5. High thermal ha'alulu kū'ē, flue kinoea wela ke alternating kiʻekiʻe a me ka haʻahaʻa, ka uhi 'ole e haule iho, a aohe mawae;
6. He laumania ka ili o ke kiʻi uhi, me kekahi hopena hoʻomaʻemaʻe ponoʻī a me ka adhesion anti-tar.
Hiki ke ʻike ʻia mai nā hiʻohiʻona huahana ʻo SY-kiʻekiʻe kiʻekiʻe ka wela a me ka anti-corrosion coating ʻaʻole kū wale i ka waika, alkali a me ka wela kiʻekiʻe, akā loaʻa pū kekahi adhesion maikaʻi, e like me ke kau ʻana i kahi papa o ka lole pale. ka paia o loko o ka rotary kiln, hiki ke kū'ē ikaika i ka kemika appoino kino, no lailapale i ka rotary kiln mai ka poino o ka waika a me ka alkali wela wela.
