1、化工原理课程设计摘要化工原理课程设计是理论联系实际的桥梁,是进行体察工程实际问题复杂性的初次尝试。通过化工原理课程设计,达到综合运用化工原理课程的基本知识,基本原理和基本计算,进行融会贯通、独立思考,在规定的时间内完成指定的化工单元操作设计任务,具有初步进行工程设计的能力;达到熟悉工程设计的基本内容,掌握化工单元操作设计的主要程序和方法;提高和进一步培养分析和解决工程实际问题的能力。此设计为釜残液冷却剂的初步设计,是一钟列管式换热器,能将釜残液从高温冷却到适当温度,釜残液走管程,冷却剂走壳程。随着化学工业发展及能源价格的提高,换热器在化工生产中占有很重要的地位。列管式换热器的优点是单位传热面
2、积大,结构紧凑,紧固传热效果好,能用多种材料,价格低廉。根据以往生产资料作为设计的数据,并进行计算,从而确定具体型号。并用AutoCAD绘制平面布置图,主要配置装配图及收回控制点的工艺流程图,最终完成设计说明书。关键词:釜残液;冷却器;初步设计26化工原理课程设计AbstractPrinciplesofchemicalengineeringcourseisdesignedtoserveasabridgebetweentheoryandpractice,istoobservethecomplexityofengineeringpracticalproblemsearlyattempts.Thr
