年产3万吨镁砖隧道窑毕业设计计算说明书 西安建筑科技大学.docVIP

1设计总说明 隧道窑的优点是操作连续、生产能力大、燃料消耗低、使用寿命较长、机械化、自动化程度较高、劳动条件较好、烧成制度易于控制及产品质量较高。 隧道窑有大小两种窑型，后者截面温差较小，调节灵活，成品率较高，设备重量较轻，制造方便。 隧道窑前设有干燥器不仅可以简化工艺、减少砖坯搬运的破损及减轻扬尘，且为全盘机械化、自动化创造条件。 目前，我国耐火材料和陶瓷工业所用隧道窑种类较多，且大多数是我国自行设计建造的，已经累积了较为丰富的经验。但在自动控制，节约能源等方面仍然有很多工作窑做。 本文详细介绍了165米年产30000吨超高温镁质耐火材料标准砖隧道窑的总体设计过程。主要包括设计技术数据，材质的选择，结构特点，压力平衡设计，燃料燃烧计算，热平衡和风机的选择。 该窑的主要特点是高温调节灵活，在不缺氧的条件下烧成温度是1600℃，燃料消耗量为395Kg/h,节约了大量的燃料，成品率为95%，全窑的自动化水平较高，实现自动控制，劳动条件较好，劳动效率较高。 关键词：超高温，隧道窑，设计，镁质 The total designed to show that Tunnel kiln has the advantage of continuous operation, large production capacity, low fuel consumption, long service life, high degree of mechanization, automation, good working conditions, firing system is easy to control and high product quality。 Tunnel kiln which has two kinds of size, type, and the latter section temperature difference is small, flexible adjustment, high yield, the device is light in weight and easy fabrication。 Before the tunnel kiln with drier can not only simplify processes, reduce adobe handling damage and reduce the dust, and to create conditions for system mechanization, automation This article introduced the 165 meters annual output of 30000 tons of ultra high temperature standard brick tunnel kiln of magnesia refractory overall design process. Main technical data including design, material selection, structural characteristics, pressure balance design, fuel combustion calculation, heat balance and the selection of fan The main characteristics of the kiln is high temperature adjustment flexible, under the condition of not hypoxia sintering temperature is 1600 ℃, and the fuel consumption of 395 kg/h, save a lot of fuel, the yield was 95%, the kiln of high automation level, to achieve automatic control, and better working conditions, high labor efficiency Key words ：Ultra high temperature ，tunnel kiln,，design,，magnesia 目录 1设计总说明 1 2原始资料的收集 6 3镁砖的生产工艺 7 3.1原料的要求 7 3.2颗粒组成及配料 7 4温度、压力和气氛制度的确定 8 4.1温度制度 8 4.2 压力制度 8 4.3气氛制度 9 5 隧道窑总体设计 9 5.1隧道窑内容纳窑车数的确定 9
