污泥脱水、干化、焚烧一体化控制系统

根据污泥脱水、干化、焚烧一体化技术,分析系统的构成,设计自动控制系统。采用PROFIBUS-DP网络实现上位机与PLC之间的连接。根据工艺流程制定系统运行策略,融入智能算法,提高污泥处理的可靠性和效率。应用In Touch 10.1组态软件开发上位机软件,绘制组态画面,实时监控整个系统的运行。针对薄弱环节增加报警参量,设置自动、手动两种运行模式,实现正常情况下工艺流程的自动化和故障检修时人工的灵活操作,提高了控制系统的智能度。

An Integrated ControI System for SIudge Dewatering,Drying and Incineration

Based on the technology integrating sludge dewatering, drying and incineration, this paper analyzes the system composition and designs an automatic control system. The upper computer and PLC is connected via PROFIBUS-DP network. Based on the technological process, the system operation strategy with intelligent algorithm is drawn up to improve the reliability and efficiency of sludge treatment. Configuration software InTouch 10.1 is used to develop upper computer software and draw configuration screens to monitor the operation of entire system on a real-time basis. Through increase of alarm parameters for weak links and setup of automatic and manual operational modes, we can realize automation under normal technological process as well as flexible operation during fault correction, thus raising the intelligence of the control system.
