酮苯脱蜡装置过滤机自动温洗程序的优化改造

Optimization and Transformation of the Automatic Warm Cleaning Program of the Filtration Machine for the Ketone Benzene Dewaxing Unit

真空过滤系统是酮苯脱蜡工艺的核心单元,过滤机效率、温洗操作效果对平稳运行和产品收率具有很大影响。文章对酮苯过滤系统自控方面存在的问题进行了分析,提出了对过滤机温洗程序优化改造的措施,实现了过滤机全自动一键温洗,可显著改善过滤机温洗效果和质量,避免了人为操作失误,大幅度降低了人工劳动强度,提高了装置平稳率、产品质量合格率,油蜡综合收率增加0.7%;同时实现了安全气密闭压力的平稳控制,避免安全气携带溶剂排空,减少了溶剂损失和环境污染,取得良好的经济和环保效益。

The vacuum filtration system is the core unit of the ketone-benzene dewaxing process.The efficiency of the filter and the effect of warm washing operation have a great impact on smooth operation and product yield.The paper analyzes the problems existing in the automatic control of the ketone-benzene filtration system,and proposes measures to optimize the warm washing program of the filter,realizing fully automatic one-key warm washing of the filtration machine.This significantly improves the washing effect and quality,re-duces human errors,and reduces manual labor intensity.The stability rate of the unit,product qualification rate are significantly im-proved,and the comprehensive yield of oil wax increased by 0.7%,realizing the stable control of the sealing pressure of the safety gas at the same time,avoiding safe gas carrying solvent empty.It also reduces solvent discharge losses,achieving good economic and envi-ronmental benefits.
