,在今后幾十年甚至是上百年之內(nèi)仍然是無可替代的基礎(chǔ)材料,對人類生活文明的重要性不言而喻?,F(xiàn)代最先進的水泥生產(chǎn)技術(shù)就是新型干法預(yù)分解窯。預(yù)分解窯是在懸浮預(yù)熱器與回轉(zhuǎn)窯之間增設(shè)分解爐,在分解爐中加入占總用量50%60%的燃料,使燃料燃燒的過程與生料碳酸鹽分解的吸熱過程在懸浮狀態(tài)或沸騰狀態(tài)下迅速進行,從而使入窯生料的分解率從懸浮預(yù)熱窯的30%40%提高到85%90%,使窯的熱負(fù)荷大為減輕,窯的壽命延長,而窯的產(chǎn)量卻可成倍增長。與懸浮預(yù)熱器窯相比,在單機產(chǎn)量相同的條件下,預(yù)分解窯具有:窯的體積小,占地面積減小,制造、運輸和安裝較易,基建投資較低,且由于一半以上的燃料是在溫度較低的分解爐內(nèi)燃燒,產(chǎn)生有害氣體NOx較少,減少了對大氣的污染。為了符合當(dāng)今水泥行業(yè)的發(fā)展需求同時也是對大學(xué)本科四年所學(xué)知識的考查,我選擇了“日產(chǎn)5000噸水泥熟料新型干法生產(chǎn)線窯尾系統(tǒng)工藝設(shè)計”這個課題作為我的畢業(yè)課題。設(shè)計范圍主要是窯尾系統(tǒng),通過配料計算、工藝平衡計算等得出結(jié)果,并結(jié)合實際對主機及附屬設(shè)備進行選型,進而對各種設(shè)備進行工藝布置,對全廠的設(shè)備進行簡單規(guī)劃。為了使本次設(shè)計各項指標(biāo)符合國家標(biāo)準(zhǔn),本次設(shè)計的過程和結(jié)果完全依據(jù)水泥工廠設(shè)計規(guī)GB50295—1999;同時設(shè)計上參考了德州大壩水泥5000 t/d 熟料生產(chǎn)線、煙臺東源5000 t/d 新型干法生產(chǎn)線等國內(nèi)先進的相近規(guī)模生產(chǎn)線,并密切聯(lián)系了畢業(yè)實習(xí)以及大學(xué)期間的認(rèn)識實習(xí)、生產(chǎn)實習(xí)等。在符合最新生產(chǎn)發(fā)展要求的基礎(chǔ)上,達到最大程度節(jié)約資源、能源,做到既降低生產(chǎn)成本又能穩(wěn)定生產(chǎn),經(jīng)濟效益和社會效益雙贏的可持續(xù)生產(chǎn)。 關(guān)鍵詞:電力系統(tǒng);燒成系統(tǒng);配料系統(tǒng);粉磨系統(tǒng) ABSTRACTCement is one of the most important building materials of the social and economic development, within the ing decades or even a century,Cement is still no substitute for basic materials, the importance of human civilization is selfevident.Modern most advanced cement production technology is NSP kiln advance deposition. Pre deposition kiln is in suspension preheater between deposing furnace with rotary kiln added, join in calciner in total amount 50% 60% of fuel, to make the fuel burning process and raw in the absorption process depose carbonate state of suspension or boiling condition, thus make rapid deposition rate of kiln raw from suspension preheater kiln 30 to 40 percent of the increased to 85 percent to 90 percent, the heat load of kiln is reduced greatly, while the prolonging furnace production but can increase exponentially. Compared with suspension preheater kiln individual output, in the same conditions, the deposition furnace with: small size, covers an area of reduced, manufacturing, transportation and installation easier, low investment in infrastructure, and because more than half of fuel is in the lower temperature burning in precalciner, produce harmful gases, and reduced the rate of less NOx atmospheric pollution.In order to meet the development needs of the cement industry today and at the same time examine the knowledge of university undergraduate course four years, I chose amp。quot。nissan 5000 tons of cement clinker NSP production line preheater system process designamp。quot。 this topic as my graduation project. Preheater system design range is mainly by ingredients calculation, craft equilibrium calculation etc, and actual results to host and affiliated equipments, and selection of equipment, process arrangement of all the equipment simple planning.In order to make the design indexes meet the national standards, the design process and the result pletely according to cement factory design rules GB502951999。 Also on the Texas dam design reference cement 5000 t/d of clinker production line, yantai dongyuan 5000 t/d NSP production line domestic advanced production line, and similar scale close contact and graduation practice during the internship, university of understanding of the production and practice, etc. In pliance with the requirements of the development of the latest production, achieve maximum based on conservation of resources, energy and to meet both reduce production cost and stable production, economic benefit and social benefit winwin sustainable production.
