丙酮-丁醇-乙醇发酵过程尾气在线监测系统设计

摘要

An on-line monitoring system of tail gas which can be applied to a strict anaerobic fermentation process is designed.Based on the Kingview software, the data communication and data analysis of the principal computer, the gas analyzer and the flow-rate meter, and the man-machine graphical interface are realized.This monitoring system can collect the real-time component information of H2 and CO2, and make an on-line prediction of the acid-producing period and the solvent-producing period during the acetone-butanol-ethanol fermentation process, which provides the real-time references for improving the production efficiency and control optimization of the actual technology.%设计一种能应用于严格无氧发酵过程的尾气在线监测系统,并通过组态王软件实现上位机与气体分析仪、流量计的数据通信、数据分析以及人机图形化交互界面.该监测系统能根据实时采集氢气与二氧化碳成分信息,在线预测丙酮-丁醇-乙醇发酵过程产酸期与产溶剂期,为提高实际工艺的生产效率和调控优化提供实时依据.
