摘要
介绍了新型组合干燥工艺在间苯二甲酸生产中的应用,重点阐述了桨叶干燥机-蒸汽管回转干燥机的工艺流程及干燥设备,分析了组合干燥工艺的特点。新系统投用后的一年内,没有物料堵塞和黏壁现象发生,未因干燥机碱洗造成COD超标,装置负荷率由80%提高到100%。
The applications of new drying technology in the isophthalic acid production are introduced. The technical process of the combined dryer equipment based on paddle dryer and steam pipe rotary dryer is highlighted. Its drying characteristics and economical efficiency are analyzed as well. The new drying system shows non-clogging and non- fouling properties within the first year, and can not cause the COD over standard by alkali washing. The load rate can be improved from 80% to 100%.
