Nkenke okwu mmalite nke Semi-akọrọ Desulfurization Technology maka Sintering Furnace Flue Gas na Iron na Steel Industry
Na 1986, Wuxi Linzhou Drying Equipment Co., Ltd, na-eji nnukwu-ọnụ ọgụgụ ịgba ihicha technology, jikọrọ ọnụ na Southwest Electric Power Design Institute, Nanjing Institute of Forestry & Chemical Industry, Chongqing University na ndị ọzọ na nkà mmụta sayensị nnyocha ụlọ ọrụ, butere pụrụ iche isiokwu nke "Research na elu sọlfọ coal rotary ịgbasa gburugburu ebe obibi nkà na ụzụ" afọ ise na-echebe nkà na ụzụ nke mba. research project.Mgbe ọtụtụ afọ nke nnyocha gasịrị, a zuru ezu set nke Chinese ụdị ngwá e guzobe na Sichuan Baima Power Plant na predetermined teknuzu indexes e zuru ezu dechara, na-eme ka a desulfurization technology nnyocha a nnukwu nzọụkwụ kwupụta ulo oru application.The isiokwu gafere nka appraisal haziri site State Department of Energy na 1990 wee nweta ihe nrite nke abụọ nke State Swardific Research Progress.
N'afọ 1998, e depụtara teknụzụ desulfurization nke obere flue flue dị ka otu n'ime ọdịnaya nke mpaghara. Wuxi linzhou ihicha akụrụngwa co., Ltd, jikọrọ ọnụ na Southwest electric ike imewe institute, Nanjing Institute of ọhịa na chemical ụlọ ọrụ, Chongqing mahadum na ndị ọzọ na nkà mmụta sayensị ụlọ ọrụ, butere oru ngo nke "ụlọ ọrụ ule na nnyocha na ọkara akọrọ flue gas desulfurization akụrụngwa". nọmba nkwekọrịta bụ SPKJ005-02 na koodu ọrụ ọrụ bụ j-16ikj98. The mesoo flue gas olu bụ 400,000 Nm3 / h.Wuxi linzhou ihicha akụrụngwa co., Ltd. bụ tumadi maka isi akụkụ nke oru ngo: elu-ọsọ centrifugal atomizing unit na 45 ton nke mmiri mmiri ịgba kwa hour.Mgbe ihe ịga nke ọma nnwale mmepụta, ọ e tinyere n'ime ọrụ na Guizhou Chuanheng Chemical Co., Ltd. na 2005. The inyeaka moto nwere ike nke 312KW na a kacha ịgba olu nke 50 t / h. Ngwá ọrụ ahụ na-arụ ọrụ zuru oke n'afọ niile na-emepụta ntụ ntụ ntụ kwa ụbọchị nke tọn 600. Ka ọ dị ugbu a, a na-etinye ọtụtụ nhazi nke nkeji ọrụ n'ọhịa nke nnukwu ụlọ ọrụ kemịkalụ. Nkeji a na-arụ ọrụ na-aga n'ihu n'ime afọ niile na arụmọrụ kwụsiri ike yana nkwụsi ike akụrụngwa a pụrụ ịdabere na ya.
Mgbe 45T / h centrifugal atomizing unit a na-mepụtara na-emepụta, nnyocha na mmepe otu nwekwara rụrụ nnyocha na structural imewe nke ọkara akọrọ desulfurization ụlọ elu, na eruba ubi analysis na desulfurization ụlọ elu na urughuru ubi. The nnyocha na mmepe otu e nwekwara a haziri iji tụọ na nyochaa akụrụngwa dị si Denmark si NIRO Company, na ka ewebata mkpa software teknụzụ maka imewe nke na-ekpo ọkụ ikuku nkesa na desulfurization ụlọ elu nke NIRO Company.He ka successively abuana ke bidding nke 125MW nkeji na Zhejiang Qian Qing Power Plant na 100MW Xiasulization nke ogologo Yutannan Power Plant na Yutannan. N'ikpe ikpe site na ọnọdụ ọnụahịa, ọ nwere nnukwu uru na ọnụahịa, ma a jụrụ ya n'ihi enweghị ọrụ azụmahịa. Ya mere, ruo ọtụtụ afọ, ọtụtụ n'ime ọkara-akọrọ desulfurization Filiks eji n'ụlọ ike osisi na-ebubata ngwá si mba ọzọ.
Na-adịbeghị anya, na mma nke mba gburugburu ebe obibi nchebe chọrọ, flue gas desulfurization nke sintering ọkụ na ígwè igwe igwe, dị ka a isi mba akara lekwasịrị mgbe flue gas desulfurization nke ike osisi, ka gua ihe dị ka 11% nke mba umu anwuru nke SO2 na ndị ọzọ ikuku na-emetọ na ígwè ụlọ ọrụ, ogo nke abụọ naanị ike ụlọ ọrụ, SO2 emissions ájá na SO2 emissions ha. emepụtara na usoro ihe nkedo maka 40% ~ 60% nke ihe ọkụkụ kwa afọ nke ụlọ ọrụ ígwè na ígwè. Ya mere, ọ dị oke mkpa maka mmepe na-adịgide adịgide nke ụlọ ọrụ ígwè na ígwè na imeziwanye gburugburu ebe obibi iji chịkwaa ihe ndị na-emetọ ihe na-emetọ ikuku gas na-emepụta ihe na-emepụta ihe na-emepụta mgbanwe nkà na ụzụ nke sintering flue.
Na-ekwu banyere ihe karịrị 10 ọrụ nke sintering flue gas desulfurization usoro na ọtụtụ desulfurization usoro imewe nkeji dị ka Shougang, Jinan, Baosteel na Tangshan, ịgba ihicha ọkara akọrọ sintering flue gas desulfurization usoro na ọtụtụ-eji. The ịgba ihicha ọkara-akọrọ desulfurization usoro nwere àgwà nke tozuru okè technology, mfe usoro eruba, elu usoro ntụkwasị obi na ihe ndị yiri ya. The desulfurization ọnụego nwere ike iru karịa 85%, SO2 emission ịta ahụhụ mgbe desulfurization ≤100mg / Nm3, na uzuzu emission ịta ahụhụ ≤50mg / Nm3.. Usoro nwere a ụfọdụ ngwa nso (8%) na United States na ụfọdụ n'ebe ọdịda anyanwụ mba Europe.Desulfurized ash nwere ike iji dị ka ciment mgbakwunye, gypsum tinyekwa, wdg.
N'ime afọ ndị na-adịbeghị anya, Wuxi Linzhou Drying Equipment Co., Ltd. ka jikọrọ aka malite mgbanwe mmepe nnyocha na flue gas desulfurization nke sintering igwe na ígwè igwe nri na Nanjing Forest Products Chemical Research Institute, Jinan Iron na Steel Group, Dalian University of technology na ụlọ ọrụ ndị ọzọ:
Na njikọ na Dalian University of Technology, a pilot osisi maka flue gas desulfurization na sintering ọkụ e hiwere na Chongqing Iron na Steel Group.
The desulfurization tower imewe nke 320m2 sintering igwe desulfurization oru ngo nke Jinan iron na ígwè otu co., Ltd. na ule ụlọ nke ụlọ 45-ton atomizing unit enwetawo mmetụta dị mma nke ngbanwe n'etiti ngwá ụlọ na ngwá ọrụ ebubata.
