摘 要 本设计说明书对所设计的年产70万平方米玻化砖辊道窑加以说明。说明书中具体论述了设计时应考虑的因素,诸如窑体结构、排烟系统、烧成系统和冷却系统等等.同时详细的进行了对窑体材料的选用、热平衡、管路、传动设计等的计算。 本次设计窑炉的燃料为液化石油气，在烧成方式上采用明焰裸烧的方法，既提高了产品的质量和档次，又节约了能源，辊子运输可减少窑内装卸制品，和窑外工序连在一起，操作方便，同时具有很高的自动化控制水平，在燃烧及温度控制上采用PID智能仪表，可以很方便的调节和稳定烧成曲线。 本说明书内容包括：窑体主要尺寸的确定、工作系统的确定、窑体材料的选择、燃料燃烧计算、热平衡计算、传动计算、管道尺寸阻力计算、风机的选型及工程材料概算。 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 level.It 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, how to choose air blower shaping and the estimation of engineerig material. 目 录 前 言 6 1 原始资料收集 7 2 窑体主要尺寸的确定 8 2.1 进窑砖坯尺寸 8 2.2 内宽的确定与排砖方法 8 2.3 内高的确定 9 2.4 烧成制度的确定 9 2.5 窑长及各带长的确定 10 2.5.1 窑长的确定 10 2.5.2 各带长的确定 11 2.5.3 辊道窑窑头、窑尾工作台长度 12 2.5.4 窑体总长度的确定 12 3 工作系统的确定 12 3.1 排烟系统 12 3.2 燃烧系统 13 3.2.1 烧嘴的设置 13 3.2.2 助燃系统 14 3.2.3 液化石油气输送系统 14 3.3 冷却系统 14 3.3.1 急冷通风系统 14 3.3.2 缓冷通风系统 15 3.3.3 快冷通风系统
