【正文】 年產(chǎn) 70 萬平方米玻化磚液化 石油氣輥道窯設(shè)計(jì) 1 摘 要 本設(shè)計(jì)說明書對所設(shè)計(jì)的年產(chǎn) 70 萬平方米?；u輥道窯加以說明。說明書中具體論述了設(shè)計(jì)時(shí)應(yīng)考慮的因素 ,諸如窯體結(jié)構(gòu)、排煙系統(tǒng)、燒成系統(tǒng)和冷卻系統(tǒng)等等 .同時(shí)詳細(xì)的進(jìn)行了對窯體材料的選用、熱平衡、管路、傳動(dòng)設(shè)計(jì)等的計(jì)算。 本次設(shè)計(jì)窯爐的燃料為液化石油氣，在燒成方式上采用明焰裸燒的方法，既提高了產(chǎn)品的質(zhì)量和檔次，又節(jié)約了能源，輥?zhàn)舆\(yùn)輸可減少窯內(nèi)裝卸制品，和窯外工序連在一起，操作方便，同時(shí)具有很高的自動(dòng)化控制水平，在燃燒及溫度控制上采用 PID 智能儀表，可以很方便的調(diào)節(jié)和穩(wěn)定燒成曲線。 本說明書內(nèi)容包括：窯 體主要尺寸的確定、工作系統(tǒng)的確定、窯體材料的選擇、燃料燃燒計(jì)算、熱平衡計(jì)算、傳動(dòng)計(jì)算、管道尺寸阻力計(jì)算、風(fēng)機(jī)的選型及工程材料概算。 年產(chǎn) 70 萬平方米玻化磚液化 石油氣輥道窯設(shè)計(jì) 2 Abstract This instruction elaborated the roller kiln. The annual production of this roller kiln is 700 thousand square meter porcelain brick. This instruction specifically elaborated the factor should considered when we designed, such as the structure of the kiln body, discharged system, burning system and the cooling system and so on, At the same time it detailed how to choose the meterial, the calculation of heat balance , the pipeline design, the transmission design to the kiln and so on. This fuel of the kiln is liquefied petroleum gas, it fires product directly. This firing way can improved the quality and scale of the product, saved the energy, and the transportation by roller may reduce loading the product. With the working procedure outside the kiln, It eased the operation. Simultaneously it has the high automation control uses the PID intelligence measuring appliance in firing and the temperature control. It can adjust the firing curve and make the temperature stably conveniently. This instruction content includes: the determination of kiln body dimension, work system, the choice of material, the calculation of fuel burning, the calculation of heat balance, the calculation of transmission, the calculation of pipeline size and resistance, 年產(chǎn) 70 萬平方米?；u液化 石油氣輥道窯設(shè)計(jì) 3 how to choose air blower shaping and the estimation of engineerig material. 年產(chǎn) 70 萬平方米玻化磚液化 石油氣輥道窯設(shè)計(jì) 4 目 錄 前 言 ................................................................... 7 1 原始資料收集 .......................................................... 7 2 窯體主要尺寸的確定 .................................................... 8 進(jìn)窯磚坯尺寸 ..................................................... 8 內(nèi)寬的確定與排磚方法 ............................................. 8 內(nèi)高的確定 ....................................................... 9 燒成制度的確定 ................................................... 9 窯長及各帶長的確定 .............................................. 10 窯長的確定 ................................................ 10 各帶長的確定 .............................................. 11 輥道窯 窯頭、窯尾工作臺(tái)長度 ................................ 12 窯體總長度的確定 .......................................... 12 3 工作系統(tǒng)的確定 ....................................................... 12 排煙系統(tǒng) ........................................................ 13 燃燒系統(tǒng) ........................................................ 13 燒嘴的設(shè)置 ................................................ 13 助燃系統(tǒng) .................................................. 14 液化石油氣輸送系統(tǒng) ........................................ 14 冷卻系統(tǒng) ........................................................ 14 急冷通風(fēng)系統(tǒng) .............................................. 14 緩冷通風(fēng)系統(tǒng) .............................................. 15 快冷通風(fēng)系統(tǒng) .............................................. 15 溫度控制系統(tǒng) .................................................... 15 熱電偶的設(shè)置 .............................................. 15 溫度儀表選型 .............................................. 16 傳動(dòng)系統(tǒng) ........................................................ 16 輥棒的選擇 ................................................ 16 傳動(dòng)裝置 .................................................. 17 輥距的確定 ................................................ 17 輥棒的聯(lián)接形式 ............................................ 17 傳動(dòng)過程 .................................................. 18 窯體附屬結(jié)構(gòu) .................................................... 18 事故處理孔 ................................................ 18 觀察孔與測溫口 ............................................ 19 膨脹縫 .................................................... 19 下?lián)鯄蜕蠙n板 ............................................ 19 鋼架結(jié)構(gòu) .................................................. 20 測壓孔 .................................................... 20 4 窯體材料確定 ......................................................... 20 窯體材料確定原則 ................................................ 20 整個(gè)窯爐的材料表 ................................................ 20 年產(chǎn) 70 萬平方米玻化磚液化 石油氣輥道窯設(shè)計(jì) 5 5 燃料及燃燒計(jì)算 ....................................................... 21 理論空氣量計(jì)算： ................................................ 22 煙氣量計(jì)算 ...................................................... 22 燃燒溫度計(jì)算 .................................................... 22 6 物料平衡計(jì)算 ......................................................... 23 7 熱平衡計(jì)算 ........................................................... 24 熱平衡示意圖 .................................................... 24 熱收入項(xiàng)目 ...................................................... 25 坯體帶入顯熱 1Q ............................................ 25 燃料帶入化學(xué)熱及顯熱 fQ ................................... 25 助燃空氣帶入顯熱 aQ ........................................ 25 預(yù)熱帶漏入空氣帶入顯熱 aQ? .................................. 25 熱支出項(xiàng)目 ...................................................... 26 熱制品帶出顯熱 2Q .......................................... 26 窯體散失熱 3Q ............................................. 26 物化反應(yīng)耗熱 4Q ............................................ 30 煙氣帶走顯熱 gQ ............................................ 31 其他熱損失 5Q .............................................. 31 列熱平衡方程并求解 .............................................. 31 列熱平衡表 ........................
