I-Flue Gas Desulfurization
Ukwethulwa Kafushane Kobuchwepheshe Be-Semi-dry Desulfurization for Sintering Furnace Flue Gas embonini ye-Iron and Steel
Ngo-1986, iWuxi Linzhou Drying Equipment Co., Ltd, isebenzisa ubuchwepheshe obukhulu bokumisa isifutho, ngokubambisana neSouthwest Electric Power Design Institute, iNanjing Institute of Forestry & Chemical Industry, iNyuvesi yaseChongqing nezinye izikhungo zocwaningo lwesayensi, yaqala isihloko esikhethekile esithi "Ucwaningo mayelana ne-high sulfur coal rotary rotary spray semi-desulfate plan yesayensi yeminyaka emihlanu" iphrojekthi yocwaningo.Ngemuva kweminyaka eminingana yocwaningo, sekumiswe isethi ephelele yemishini yesitayela samaShayina eSichuan Baima Power Plant futhi izinkomba zezobuchwepheshe ezinqunywe kusengaphambili seziqediwe ngokugcwele, okwenza lolu cwaningo lobuchwepheshe be-desulfurization lube isinyathelo esikhulu ekusetshenzisweni kwezimboni.Isihloko saphumelela ukuhlolwa kobuchwepheshe okuhlelwe uMnyango Wezamandla Wezwe ngo-1990 futhi sawina umklomelo wesibili we-State Progress Scientific Award.
Ngo-1998, ubuchwepheshe be-semi-dry flue gas desulfurization bafakwa ohlwini njengokuqukethwe kokunye okwenziwe kwasendaweni. IWuxi linzhou drying equipment co., ltd, ngokubambisana neSouthwest electric power design Institute, iNanjing Institute of Forestry and Chemical industry, inyuvesi yaseChongqing nezinye izikhungo zocwaningo lwesayensi, yenze iphrojekthi "yokuhlolwa kwezimboni kanye nocwaningo mayelana nemishini yokususa igesi eyomile". inombolo yenkontileka bekungu-SPKJ005-02 kanye nenombolo yekhodi yephrojekthi kwakungu-j-16ikj98.Ivolumu yegesi ephathwayo engu-400,000 Nm3/h.Wuxi linzhou drying equipment co., ltd. ibhekene kakhulu nezingxenye eziyinhloko zephrojekthi: iyunithi ye-atomizing ye-centrifugal enesivinini esikhulu namathani angu-45 esifutho esiwuketshezi ngehora.Ngemva kokukhiqizwa kwesivivinyo esiyimpumelelo, yaqala ukusebenza e-Guizhou Chuanheng Chemical Co., Ltd. ngo-2005. Injini eyisisetshenziswa inamandla angu-312KW kanye nevolumu yesifutho esiphezulu esingu-50 t/h. Imishini isebenza ngomthamo ogcwele unyaka wonke ngokukhiqizwa kwempushana eyomile yansuku zonke yamathani angu-600. Kuze kube manje, amasethi amaningi amayunithi asetshenziswe emkhakheni wezimboni zamakhemikhali ezinkulu. Amayunithi asebenza ngokuqhubekayo unyaka wonke ngokusebenza okuzinzile nokuzinza okuthembekile kwemishini.
Ngenkathi i-45T/h centrifugal atomizing unit isathuthukiswa futhi ikhiqizwa, ithimba locwaningo nentuthuko liye lenza ucwaningo ngomklamo wesakhiwo sombhoshongo we-semi-dry desulfurization, ukuhlaziya insimu yokugeleza embhoshongweni we-desulfurization kanye nenkundla yezinhlayiyana. Ithimba locwaningo nentuthuko liphinde lahlelwa ukuze lilinganise futhi lihlaziye amathuluzi angenisiwe evela eNkampanini yaseDenmark i-NIRO, futhi lethule ubuchwepheshe besofthiwe obufanele bomklamo wokusabalalisa umoya oshisayo nombhoshongo we-desulfurization weNkampani ye-NIRO. Ubambe iqhaza ngokulandelana ekubhidelweni kwamayunithi angu-125MW e-Zhejiang Qian Qing00M0M Power Plant ye-Xiaoo Power Plant kanye neyunithi engu-1 ye-Xiao Power Plant kanye ne-1. amaphrojekthi we-semi-dry desulfurization. Uma sibheka isimo sokubhida, unezinzuzo ezinkulu ngentengo, kodwa wenqatshiwe ngenxa yokuntuleka kokusebenza kwezohwebo. Ngakho-ke, iminyaka eminingi, izinqubo eziningi ze-semi-dry desulfurization ezisetshenziswa ezitshalweni zamandla zasekhaya ziyimishini engenisiwe evela phesheya.
Eminyakeni yamuva nje, ngokuthuthukiswa kwezidingo zokuvikelwa kwemvelo kazwelonke, i-flue gas desulfurization yesithando somlilo ezigayweni zensimbi, njengenhloso ebalulekile yokulawula kazwelonke ngemuva kwe-flue gas desulfurization yezitshalo zamandla, ibalele cishe i-11% yokukhishwa kukazwelonke kwe-SO2 nezinye izinto ezingcolisa umoya embonini yensimbi, ukukhishwa kwesibili kwe-CO2 kuphela, i-CO2 kuphela. kanye nokunye ukungcola okukhiqizwe ohlelweni lokucwilisa amanzi kubalelwa ku-40% ~ 60% wezinto ezikhishwa minyaka yonke embonini yensimbi neyensimbi.Ngakho-ke, kubaluleke kakhulu ekuthuthukisweni okusimeme kwemboni yensimbi nensimbi kanye nokuthuthukiswa kwemvelo ukuze kulawulwe ukukhishwa kwezinto ezingcolisayo ezivela kugesi we-sintering flue kanye nokwenza uguquko lwe-desunterfuration gas desunterfuration.
Ibhekisela kubasebenzisi abangaphezu kwe-10 benqubo ye-sintering flue gas desulfurization kanye nenqwaba yamayunithi enqubo ye-desulfurization efana ne-Shougang, iJinan, i-Baosteel ne-Tangshan, inqubo yokumisa i-semi-dry sintering flue desulfurization isetshenziswa kabanzi. Inqubo yokumisa isifutho se-semi-dry desulfurization inezici zobuchwepheshe obuvuthiwe, ukugeleza kwenqubo elula, ukwethembeka okuphezulu kwesistimu nokunye okunjalo. Izinga le-desulfurization lingafinyelela ngaphezu kwe-85%, i-SO2 emission concentration after desulfurization ≤100mg/Nm3, kanye ne-dust emission concentration ≤50mg/Nm3..Inqubo inebanga elithile lesicelo (8%) e-United States nakwamanye amazwe asentshonalanga ye-Europe.Umlotha we-Desulfurized ungasetshenziswa njengesengezo se-cement, njll.
Eminyakeni yamuva nje, i-Wuxi Linzhou Drying Equipment Co., Ltd. yethule ngokuhlanganyela ucwaningo lwentuthuko eguquguqukayo mayelana nokuchithwa kwegesi ephuma emanzini emshinini wokugaya emishinini yensimbi ene-Nanjing Forest Products Chemical Research Institute, iJinan Iron ne-Steel Group, i-Dalian University of technology nezinye izikhungo:
Ngokuhlanganyela ne-Dalian University of Technology, isikhungo sokulinga sokususa igesi e-flue esithandweni somlilo sasungulwa e-Chongqing Iron and Steel Group.
Idizayini yombhoshongo we-desulfurization wephrojekthi ye-320m2 sintering desulfurization yomshini weJinan iron and steel group co., Ltd. kanye nokuhlolwa kwasekhaya kweyunithi ye-atomizing yasekhaya engamathani angama-45 kuzuze umphumela omuhle wokushintsha phakathi kwezinto zasekhaya nezisetshenziswa ezingenisiwe.
