硫酸生产过程自动串酸系统的开发

Development of Automatic Sulphuric Acid Connecting System for the Production Process

介绍硫酸生产过程自动串酸系统的组成,简述了冶炼烟气制酸条件下,该系统的多变量、时变、时滞等特性,并由此采取的控制方式。系统投运以来,不断对控制方案和参数进行完善,使其更适应工艺生产的要求,取得良好的控制效果。

The composition of the automatic sulphuric acid-connecting system in the process of production is introduced. The suitable control method is taken to adapt to multi-variable, time variable and dead time features of the system. The control program and parameters have been continually improved in order to meet the requirement of production process and perfect control effect has been achieved since the system was put into operation.
