摘要
基于苯酐这一装置,在出现气冷堵塞现象之后,会极大降低生产产量。文章首先概述了苯酐工艺流程,然后探究了苯酐气体冷却器,其中包括工作原理、气体冷却器堵塞、堵塞之后的煮洗措施,以期能为有关人士提供参考。
Based on the device of phthalic anhydride,the production will be greatly reduced after the phenomenon of gas cooling blockage.This paper first summarizes the process of phthalic anhydride and then explores the phthalic anhydride gas cooler,including the working principle,gas cooler blockage,boiling and washing measures after blockage,in order to provide reference for people.
