摘要
基于国内某化纤厂PTA干燥机更新改造项目,介绍了PTA干燥机的改造设计过程,从质量衡算、热量衡算及换热面积计算、长径比及布管设计、停留时间和填充率、斜度和转速等方面,重点介绍了PTA蒸汽管回转干燥机的工艺设计计算过程。
Based on the reconstruction project of PTA dryer in a chemical fiber factory in China,this paper introduces the design process of PTA dryer. The process design and calculation process of PTA steam pipe rotary dryer are introduced in detail in terms of the calculation of quality balance,heat balance and heat transfer area,length to diameter ratio,pipe layout design,residence time and filling rate,slope and rotation speed.
