Kuchotsa gasi wa Flue
Kuyamba Mwachidule kwa Semi-dry Desulfurization Technology ya Sintering Furnace Flue Gas mu Iron and Steel Industry
Mu 1986, Wuxi Linzhou Drying Equipment Co., Ltd, pogwiritsa ntchito luso lalikulu loyanika kutsitsi, limodzi ndi Southwest Electric Power Design Institute, Nanjing Institute of Forestry & Chemical Viwanda, Chongqing University ndi mabungwe ena asayansi, adatenga mutu wapadera wa "Research on high sulfure malasha ozungulira kutsitsi theka-umisiri wowuma wachisanu ndi chisanu ndi chiwiri wa sayansi ya chilengedwe" Research project.After zaka zingapo za kafukufuku, athunthu a Chinese-style zida zakhazikitsidwa mu Sichuan Baima Power Plant ndipo zolozera zaluso zodziwikiratu zamalizidwa mokwanira, zomwe zimapangitsa kuti kafukufuku waukadaulo wa desulfurization akhale gawo lalikulu lakugwiritsa ntchito mafakitale. Nkhaniyi idapambana mayeso aukadaulo omwe adakonzedwa ndi dipatimenti yamagetsi ya Boma mu 1990 ndipo adapambana mphotho yachiwiri ya State Scientific Award.
Mu 1998, ukadaulo wa semi-dry flue gas desulfurization udalembedwa kuti ndi chimodzi mwazinthu zomwe zidakhazikitsidwa. Wuxi linzhou drying equipment co., Ltd, mothandizana ndi Southwest Electric Power Design Institute, Nanjing Institute of Forestry and Chemical industry, Chongqing University ndi mabungwe ena ofufuza zasayansi, adagwira ntchito ya "mayeso a mafakitale ndi kafukufuku pazida zowuma za gasi desulfurization". nambala ya mgwirizano inali SPKJ005-02 ndipo nambala ya code ya pulojekiti inali j-16ikj98.Volume ya gasi wa flue wothiridwa ndi 400,000 Nm3/h.Wuxi linzhou drying equipment co., ltd. makamaka ali ndi udindo wa zigawo zikuluzikulu za polojekiti: mkulu-liwiro centrifugal atomizing unit ndi 45 matani madzi kutsitsi pa ola.Atatha bwino kupanga mayesero, anaikidwa mu ntchito Guizhou Chuanheng Chemical Co., Ltd. Zipangizozi zimagwira ntchito mokwanira chaka chonse ndi kupanga ufa wowuma wa tsiku ndi tsiku wa matani 600. Mpaka pano, magulu ambiri amagulu akugwiritsidwa ntchito m'munda wamakampani akuluakulu a mankhwala. Magawowa amagwira ntchito mosalekeza chaka chonse ndikuchita bwino komanso kukhazikika kwa zida zodalirika.
Pamene 45T/h centrifugal atomizing wagawo ikupangidwa ndi kupangidwa, kafukufuku ndi chitukuko gulu lachitanso kafukufuku structural kamangidwe ka theka-youma desulfurization nsanja, otaya munda kusanthula mu nsanja desulfurization ndi tinthu munda. Gulu lofufuza ndi chitukuko lakonzedwanso kuti liyese ndi kusanthula zida zomwe zatumizidwa kuchokera ku NIRO Company ya ku Denmark, ndipo lakhazikitsa matekinoloje oyenerera a mapulogalamu opangira makina opangira mpweya wotentha ndi nsanja ya desulfurization ya NIRO Company. Iye adatenga nawo gawo motsatizana potsatsa mayunitsi a 125MW mu Zhejiang Qian Qing Qing00M Power Plant ndi 1Mt Power Plant 1. ntchito za semi-dry desulfurization. Poyang'ana pazochitika zamalonda, ali ndi ubwino waukulu pamtengo, koma wakanidwa chifukwa cha kusowa kwa malonda. Chifukwa chake, kwa zaka zambiri, njira zambiri za semi-dry desulfurization zomwe zimagwiritsidwa ntchito m'mafakitale amagetsi apanyumba ndi zida zotumizidwa kuchokera kunja.
M'zaka zaposachedwapa, ndi kusintha kwa dziko zofunika chitetezo zachilengedwe, ndi chitoliro mpweya desulfurization wa sintering ng'anjo mu zitsulo mphero, monga kiyi dziko kulamulira chandamale pambuyo chitoliro mpweya desulfurization zomera mphamvu, wakhala mlandu pafupifupi 11% ya mpweya dziko la SO2 ndi zoipitsa zina mumlengalenga mu makampani zitsulo, kusanja wachiwiri wa SO2, fumbi makampani zitsulo, kusanja wachiwiri wa SO2, CO2, 2, SO ndi zoipitsa zina kwaiye mu ndondomeko sintering nkhani 40% ~ 60% ya mpweya wapachaka wa chitsulo ndi zitsulo industry.Choncho, ndi zofunika kwambiri kwa chitukuko zisathe za chitsulo ndi zitsulo makampani ndi kusintha kwa chilengedwe kulamulira umuna wa zoipitsa mpweya wa sintering chitoliro ndi kuchita kusintha kwa sayansi desunterfurization flue.
Ponena za ogwiritsa ntchito opitilira 10 a sintering flue gasi desulfurization ndi mayunitsi ambiri a desulfurization process monga Shougang, Jinan, Baosteel ndi Tangshan, kupopera mbewu mankhwalawa theka-dry sintering flue gas desulfurization process amagwiritsidwa ntchito kwambiri. The kutsitsi kuyanika theka-youma desulfurization ndondomeko ali makhalidwe a luso okhwima, yosavuta otaya ndondomeko, mkulu dongosolo kudalirika ndi zina zotero. Mlingo wa desulfurization ungafikire kuposa 85%, SO2 umuna ndende pambuyo desulfurization ≤100mg/Nm3, ndi fumbi umuna ndende ≤50mg/Nm3..Njirayi imakhala ndi ntchito zosiyanasiyana (8%) ku United States ndi mayiko ena akumadzulo kwa Ulaya. Phulusa la Desulfurized lingagwiritsidwe ntchito monga matope owonjezera a simenti, etc.
M'zaka zaposachedwa, Wuxi Linzhou Drying Equipment Co., Ltd. wakhala pamodzi anapezerapo kafukufuku adaptive chitukuko cha chitoliro desulfurization mpweya wa sintering makina mu mphero zitsulo ndi Nanjing Forest Products Chemical Research Institute, Jinan Iron ndi Zitsulo Gulu, Dalian University luso ndi mabungwe ena:
Mogwirizana ndi Dalian University of Technology, malo oyendetsa gasi ochotsa sulfurization mu ng'anjo ya sintering adakhazikitsidwa ku Chongqing Iron and Steel Group.
Mapangidwe a nsanja ya desulfurization ya 320m2 sintering machine desulfurization project ya Jinan iron and steel group co., Ltd. ndi kuyesa kwapakhomo kwa 45-ton atomizing unit yapeza zotsatira zabwino zosinthira pakati pa zida zapakhomo ndi zida zotumizidwa kunja.
