聚酯生产线真空 EG喷淋冷凝器设计的改进

摘要

We made autonomous optimization design to the polyester EG vacuum spray condenser , and reform in engineering practice.The spray condenser to the problems of the fouling, necking, and plugging has been improved obviously, The good effects was obtinecl.The spray condenser structure is improved.The spraying effect is better, can realize simply to dismount the nozzle for cleaning on-line, and make the operation simple.%通过分析比较不同聚酯工艺装置的真空EG喷淋冷凝器，结合不同类型冷凝器的优缺点，对聚酯真空EG喷淋冷凝器进行自主优化设计，并在工程实践中进行设计改造，对喷淋冷凝器的结垢、缩径和堵塞[1]等问题有了明显的改善，起到很好的效果。本设计是在满足工艺要求前提下，对喷淋冷凝器的结构进行了一定的改进，使得喷淋效果更佳，可简单实现在线拆换喷嘴进行清洗，使得操作简单化。
