℃左右的窯尾熱煙氣接觸的面積大,故傳熱速度快、熱效率高。連續(xù) 10 年,每年水泥的規(guī)劃目標(biāo)與實(shí)際水泥產(chǎn)量,相差幾乎都在一億噸以上。2022 年,規(guī)劃水泥產(chǎn)量 億噸,實(shí)際生產(chǎn) 億噸;2022 年,規(guī)劃水泥產(chǎn)量 億噸,實(shí)際生產(chǎn) 億噸;2022 年,規(guī)劃水泥產(chǎn)量 億噸,實(shí)際生產(chǎn) 億噸;2022 年,規(guī)劃水泥產(chǎn)量 億噸,實(shí)際生產(chǎn) 億噸。我國(guó)已經(jīng)成為名副其實(shí)的水泥生產(chǎn)大國(guó),但總體水平不高,不是水泥工業(yè)強(qiáng)國(guó),其表現(xiàn)有以下的基本特點(diǎn):(1)總產(chǎn)量的生產(chǎn)能力世界第一 我國(guó)水泥工業(yè)從 1978 年至 1985 年水泥產(chǎn)量由 6500 萬(wàn)噸發(fā)展到 億噸,7 年增長(zhǎng)約 8000 萬(wàn)噸,平均年增長(zhǎng) 1140 萬(wàn)噸;1995 年到 2022 年水泥產(chǎn)量由 億噸到20 世紀(jì)末預(yù)計(jì)可達(dá) 億噸,5 年增長(zhǎng)了 1 億噸,平均年增長(zhǎng) 2022 萬(wàn)噸。二十世紀(jì)八十年代末,我國(guó)已建成二十多套 2022t/d 新型干法水泥生產(chǎn)線,通過(guò)引進(jìn)消化國(guó)外 20 項(xiàng)先進(jìn)技術(shù)來(lái)改進(jìn)我們自行開發(fā)的設(shè)備,是我國(guó) 2022t/d 新型干法水泥生產(chǎn)線漸趨成熟,雙陽(yáng)水泥廠的建成并達(dá)標(biāo)生產(chǎn)就是成熟的標(biāo)志。七十年代末我國(guó)分別從日本、澳大利亞、丹麥等國(guó)引進(jìn)了大、中型的預(yù)分解窯干法生產(chǎn)成套設(shè)備,并在建成投產(chǎn)后取得良好的技術(shù)經(jīng)濟(jì)效益。而與此同時(shí),發(fā)展中國(guó)家水泥需求量不斷增大,帶動(dòng)了那里的水泥工業(yè)的迅猛發(fā)展,特別是東亞、西南亞地區(qū),1998 年亞洲國(guó)家生產(chǎn)的水泥幾乎占到了世界水泥總量的 60%以上。這種發(fā)展趨勢(shì)今后仍將保持下去。生產(chǎn)水泥雖然需要比較多的資源,但是水泥與砂、石等集料所制成的混凝土則是一種低能耗型建筑材料,因此水泥工業(yè)的發(fā)展對(duì)保證國(guó)家建設(shè)的順利進(jìn)行具有十分重要的作用。關(guān)鍵詞:電力系統(tǒng);燒成系統(tǒng);配料系統(tǒng);粉磨系統(tǒng) 2 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 nissan 5000 tons of cement clinker NSP production line preheater system process design 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。為了使本次設(shè)計(jì)各項(xiàng)指標(biāo)符合國(guó)家標(biāo)準(zhǔn),本次設(shè)計(jì)的過(guò)程和結(jié)果完全依據(jù)水泥工廠設(shè)計(jì)規(guī) GB50295—1999;同時(shí)設(shè)計(jì)上參考了德州大壩水泥 5000 t/d 熟料生產(chǎn)線、煙臺(tái)東源 5000 t/d 新型干法生產(chǎn)線等國(guó)內(nèi)先進(jìn)的相近規(guī)模生產(chǎn)線,并密切聯(lián)系了畢業(yè)實(shí)習(xí)以及大學(xué)期間的認(rèn)識(shí)實(shí)習(xí)、生產(chǎn)實(shí)習(xí)等。為了符合當(dāng)今水泥行業(yè)的發(fā)展需求同時(shí)也是對(duì)大學(xué)本科四年所學(xué)知識(shí)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(jì)”這個(gè)課題作為我的畢業(yè)課題。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(guò)程與生料碳酸鹽分解的吸熱過(guò)程在懸浮狀態(tài)或沸騰狀態(tài)下迅速進(jìn)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(zhǎng),而窯的產(chǎn)量卻可成倍增長(zhǎng)。摘 要水泥是社會(huì)經(jīng)濟(jì)發(fā)展最重要的建筑材料之一,在今后幾十年甚至是上百年之內(nèi)仍然是無(wú)可替代的基礎(chǔ)材料,對(duì)人類生活文明的重要性不言而喻?,F(xiàn)代最先進(jìn)的水泥生產(chǎn)技術(shù)就是新型干法預(yù)分解窯。與懸浮預(yù)熱器窯相比,在單機(jī)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(yùn)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(duì)大氣的污染。設(shè)計(jì)范圍主要是窯尾系統(tǒng),通過(guò)配料計(jì)算、工藝平衡計(jì)算等得出結(jié)果,并結(jié)合實(shí)際對(duì)主機(jī)及附屬設(shè)備進(jìn)行選型,進(jìn)而對(duì)各種設(shè)備進(jìn)行工藝布置,對(duì)全廠的設(shè)備進(jìn)行簡(jiǎn)單規(guī)劃。在符合最新生產(chǎn)發(fā)展要求的基礎(chǔ)上,達(dá)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(jì)效益和社會(huì)效益雙贏的可持續(xù)生產(chǎn)。 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.Key words: Electric power system;Firing system ;Batching system;Griding system 3 目 錄摘要………………………………………………..…….….……………..IABSTRACT…………………………………….……………………..…………….II1 前言……….…………………………………………………………….….……...……..12 建廠基礎(chǔ)資料............…….……..….………………………….…..….………….4 設(shè)計(jì)題目………………………… ………………………………………..4 建廠條件………………………………….……… ………...………………..4 原始數(shù)據(jù)……………………………………….… ………………………...4 原燃料化學(xué)成分…………………………….… ………………………...4 原、燃料水分……………………………….… ………………………...5 煙煤的工業(yè)分析…………………………….… ………………………...5 煙煤的元素分析…………………………….… ………………………...5 生產(chǎn)方法和窯型的選擇…………………….… ………………………...53 全廠工藝平衡計(jì)算… ………………….…………………………….…………………...7 配料計(jì)算……………………………………………….… ………………………...7 應(yīng)用基低位發(fā)熱量…………………………….… ………………………....7 三個(gè)率值的選擇…………………………….… …………………………....7 煤灰沉落率的計(jì)算………………………….… …………………………... 8 熟料化學(xué)成分的要求…………………….… ……………………………... 8 以 100kg 干熟料為基準(zhǔn)列累加試湊表…….… …………………………... .8 干原料料耗的計(jì)算………………………………………… ……………... .9 生料干原料配合比的計(jì)算………………………………… ……………... .9 生料濕原料配合比的計(jì)算………………………………… ……………... .9 物料平衡計(jì)算…………………………………………………… ……………......10 物料平衡計(jì)算在設(shè)計(jì)中的作用…………………………………… ……. 10 參數(shù)選擇及窯規(guī)格的確定………………………………… …………….. 10 全廠物料平衡計(jì)算………………………………………………… ……. 11 原、燃料需要量的計(jì)算及物料平衡 4 表…………………………… ……...134 工藝設(shè)備選型與計(jì)算…………………………………….… …………………………....16 工藝設(shè)備選型與計(jì)算的目的……………………….… ………………………….16. 設(shè)備選型……………………………………… ……………… ……………. ..17 石灰石破碎設(shè)備的選型…………………………………… ……………. .17 生料閉路磨的設(shè)備選型…………………………………… ……………………18 回轉(zhuǎn)窯選型…………………………………… ……………………………. 18 烘干機(jī)設(shè)備的選型………………………………………… ……………. .19 煤磨的選型…………………………………… …………………………. .20 水泥磨的設(shè)備選型………………………………………… ……………. .21 包裝機(jī)的設(shè)備選型………………………………………… ……………. .22 主機(jī)平衡表見(jiàn)表…………………………………………… ……………. .22 堆場(chǎng)(棚)的選型設(shè)計(jì)………………………………………………… …………23 石灰石預(yù)均化堆場(chǎng)的計(jì)算 …… …………………………………………. 24 砂巖預(yù)均化堆場(chǎng)的計(jì)算………………………………………… …….…. 25 濕鐵粉、鋁土礦聯(lián)合堆棚……………………………………… ………. . 26 煤預(yù)均均化堆場(chǎng)的計(jì)算………………………………………… …
