Ukuchithwa kweGesi yeFlue
Intshayelelo emfutshane yeTekhnoloji ye-Semi-dry Desulfurization ye-Sintering Furnace Flue Gas kwi-Iron kunye ne-Steel Industry.
Ngo-1986, iWuxi Linzhou Drying Equipment Co., Ltd, isebenzisa itekhnoloji yokumisa isitshizi esikhulu, ngokubambisana neSouthwest Electric Power Design Institute, iNanjing Institute of Forestry & Chemical Industry, iYunivesithi yaseChongqing kunye namanye amaziko ophando lwenzululwazi, yathatha isihloko esikhethekileyo esithi "Phanda kwi-high sulfure yamalahle ajikelezayo ngokutshiza iteknoloji yokutshiza semi-omile ye-desulfure kwi-teknoloji ye-desulfate yesihlanu" Iprojekthi yophando emva kweminyaka eliqela yophando, iseti epheleleyo yezixhobo zesimbo saseTshayina ziye zamiselwa kwiSityalo saMandla saseSichuan Baima kwaye izalathisi zobugcisa ezimiselwe kwangaphambili ziye zagqitywa ngokupheleleyo, nto leyo eyenza olu phando lobuchwephesha lwe-desulfurization lube linyathelo elikhulu elibhekiselele kwi-industrial application.Isifundo siphumelele uvavanyo lobugcisa oluququzelelwe liSebe lezaMandla likaRhulumente ngo-1990 kwaye laphumelela ibhaso lesibini leMbasa yeNzululwazi yoPhando lweSizwe.
Ngo-1998, itekhnoloji ye-semi-dry flue gas desulfurization yadweliswa njengenye yezinto eziqulethwe kwindawo. IWuxi linzhou drying equipment co., Ltd, ngokudibeneyo neziko loyilo lwamandla ombane asemazantsi-ntshona, iziko leNanjing lamahlathi kunye neshishini lemichiza, iyunivesithi yaseChongqing kunye namanye amaziko ophando lwezenzululwazi, bathathe iprojekthi "yovavanyo lwamashishini kunye nophando malunga nezixhobo zegesi eyomileyo ye-flue desulfurization". inombolo yekhontrakthi yayiyi-SPKJ005-02 kunye nenombolo yekhowudi yeprojekthi yayingu-j-16ikj98.Umthamo wegesi ye-flue enyangweyo yi-400,000 Nm3/h.Wuxi linzhou drying equipment co., ltd. ikakhulu uxanduva lwamacandelo aphambili eprojekthi: isantya esiphezulu se-centrifugal iyunithi ye-atomizing ene-45 yeetoni zesitshizi solwelo ngeyure.Emva kokuveliswa kovavanyo oluyimpumelelo, yafakwa ekusebenzeni eGuizhou Chuanheng Chemical Co., Ltd. ngo-2005. Injini encedisayo inamandla e-312KW kunye nomthamo wokutshiza ongaphezulu we-50 t. Isixhobo sisebenza ngomthamo opheleleyo unyaka wonke kunye nemveliso yepowder eyomileyo yonke imihla yeetoni ezingama-600. Ukuza kuthi ga ngoku, iiseti ezininzi zeeyunithi ziye zafakwa kwintsimi yoshishino lweekhemikhali ezinkulu. Iiyunithi zisebenza ngokuqhubekayo unyaka wonke kunye nokusebenza okuzinzileyo kunye nozinzo oluthembekileyo lwezixhobo.
Ngelixa i-45T / h iyunithi ye-atomizing ye-centrifugal iphuhliswa kwaye iveliswa, iqela lophando kunye nophuhliso liye laqhuba uphando malunga noyilo lwesakhiwo se-semi-dry desulfurization tower, uhlalutyo lwentsimi ye-flow field kwi-desulfurization tower kunye nentsimi ye-particle. Iqela lophando kunye nophuhliso likwaququzelelwe ukulinganisa kunye nokuhlalutya izixhobo ezingeniswe kwiNkampani ye-NIRO yaseDenmark, kwaye iye yazisa ubugcisa besoftware efanelekileyo yoyilo losasazo lomoya oshushu kunye nenqaba ye-desulfurization ye-NIRO Company.Uthathe inxaxheba ngokulandelelana kwibhidi yeeyunithi ze-125MW kwi-Zhejiang Qian Qing00M Power Plant kwi-Plant Power Plant ye-XiaoM kunye neyunithi ye-XiaoM Power Plant iiprojekthi ze-semi-dry desulfurization. Ukuqwalasela imeko yokubhida, unenzuzo enkulu kwixabiso, kodwa uye wanqatshwa ngenxa yokungabikho kokusebenza kwezorhwebo. Ke ngoko, iminyaka emininzi, uninzi lweenkqubo ze-semi-dry desulfurization ezisetyenziswa kwizityalo zamandla zasekhaya zithunyelwa ngaphandle izixhobo ezivela phesheya.
Kwiminyaka yakutshanje, kunye nokuphuculwa kweemfuno zokhuselo lokusingqongileyo kazwelonke, igesi flue desulfurization of sintering eziko kwizixhobo zokusila zentsimbi, njengento ekujoliswe kuyo ulawulo lwesizwe emva desulfurization igesi flue desulfurization yezityalo zamandla, iye yaba malunga 11% yokukhutshwa kwesizwe SO2 kunye nezinye izinto ezingcolisa umoya kwishishini lentsimbi, ukuthunyelwa kwesibini phakathi kwabo, i-CO2 kuphela kwi-emissions yothuli, i-CO2 kuphela kwi-2. kunye nolunye ungcoliseko oluveliswe kwinkqubo ye-sintering akhawunti ye-40% ~ 60% yokukhutshwa konyaka kushishino lwentsimbi kunye nentsimbi. Ngoko ke, kubaluleke kakhulu kuphuhliso oluzinzileyo loshishino lwentsimbi kunye nentsimbi kunye nokuphuculwa kwemekobume ye-ikholoji ukulawula ukukhutshwa kwezinto ezingcolileyo kwi-sintering flue gas kunye nokwenza inguqu ye-technological flue de susnterfuation.
Ngokubhekiselele kubasebenzisi abangaphezu kwe-10 benkqubo ye-sintering flue flue desulfurization kunye nenani leeyunithi zoyilo lwenkqubo ye-desulfurization ezifana neShougang, iJinan, iBaosteel kunye neTangshan, inkqubo yokutshiza i-semi-dry sintering flue desulfurization isetyenziswa ngokubanzi. Inkqubo yokutshiza i-semi-dry desulfurization ineempawu zobuchwepheshe obuvuthiweyo, ukuhamba kwenkqubo elula, ukuthembeka kwenkqubo ephezulu kunye nokunye okunjalo. Izinga le-desulfurization lingafikelela ngaphezu kwe-85%, i-SO2 emission concentration emva kwe-desulfurization ≤100mg / Nm3, kunye ne-concentration ye-dust emission concentration ≤50mg / Nm3..Inkqubo inoluhlu oluthile lwesicelo (8%) e-United States nakwamanye amazwe asentshona yeYurophu.
Kwiminyaka yakutshanje, iWuxi Linzhou Drying Equipment Co., Ltd. iye yasungula ngokudibeneyo uphando lophuhliso kwi-flue gas desulfurization yomatshini wokucoca kwiintsimbi zentsimbi kunye neNanjing Forest Products Chemical Research Institute, iJinan Iron kunye neQela leNsimbi, iDyunivesithi yaseDalian yobuchwephesha kunye namanye amaziko:
Ngokudityaniswa neDyunivesithi yeTekhnoloji yaseDalian, iplanti yokulinga irhasi yeflue desulfurization kwi sintering furnace yasekwa eChongqing Iron and Steel Group.
Uyilo lwenqaba ye-desulfurization yeprojekthi ye-320m2 ye-sintering machine desulfurization yeJinan yentsimbi kunye neqela lentsimbi., Ltd. kunye novavanyo lwasekhaya lweyunithi ye-atomizing yeetoni ezingama-45 yasekhaya iphumelele isiphumo esihle sokutshintsha phakathi kwezixhobo zasekhaya kunye nezixhobo ezithunyelwa ngaphandle.
