【摘要】：垃圾焚烧发电是目前国内处理垃圾的重要方式之一,经过多年的国产化技术革新,垃圾焚烧炉从普遍进口改为大部分国产化,自动化控制系统也是全进口变为国产化。和利时MACS V5.2.4控制系统编写容易、扩展性强,维护轻松,自动控制系统整体运行稳定、可靠。垃圾焚烧已经成为各城市处理垃圾的主要方式,在整个垃圾焚烧流程中,垃圾在炉排上燃烧过程是最为重要的环节,燃烧时的温度直接决定了处理垃圾的效率及质量,也是影响二次污染的决定环节。机械炉排是焚烧垃圾流程中的核心设备,所以通过对机械炉排整体DCS控制,实现对燃烧温度的自动控制,对我国城市垃圾焚烧处理、节能减排有非常重要的意义。本文首先说明课题研究的背景和意义,对垃圾在机械炉排上焚烧的控制系统和工艺流程进行学习和研究,介绍机械炉排在垃圾焚烧时的工作原理和相关温度场的关系。然后根据垃圾焚烧的特性,提出了基于DCS的垃圾机械炉排炉自动燃烧控制系统总体方案,并对DCS硬件进行设计、选型、安装及调试,对控制系统软件进行设计、实现及调试优化,最后整套系统投入实际应用,运行的状况和结果表明控制系统实现了既定的控制目标。本文设计并实现的机械炉排炉自动燃烧控制系统,已应用在浙江省宁波市。目前该系统已投入运行,整套炉排控制系统运行良好,操作简洁方便。实现了垃圾在焚烧时的燃烧自动化,垃圾机械炉排炉自动燃烧控制系统运行良好,调节速度快,系统稳定性能好,抗击干扰能力强,取得了非常好的效果。
[Abstract]:Waste incineration power generation is one of the important way for domestic waste disposal at present, the domestic technology innovation for many years, garbage incinerator from the general import for most of the localization, automatic control system is imported into China. Hollysys MACS V5.2.4 control system written in easy expansibility, easy maintenance, automatic control system of the overall operation stable and reliable. Waste incineration has become a main way of waste disposal of the city, in the whole process of waste incineration, waste on the grate combustion process is the most important part of the combustion temperature directly affects the efficiency and quality of waste disposal, but also affect the decision to link two pollution. Mechanical grate incineration is the core equipment in the process of garbage, so through control of the mechanical grate DCS, realize the automatic control of the combustion temperature, combustion of burning waste in our country city, energy saving Has a very important significance. This paper shows the reduction of background and significance of the research, study and Research on the control system and the process of waste incineration in mechanical grate, the working principle of mechanical grate in waste incineration and temperature field. Then according to the characteristics of waste incineration, the automatic combustion control the overall scheme of the system of waste mechanical grate furnace based on DCS, and the DCS design, hardware selection, installation and commissioning, to design the control system software implementation and debugging, optimization, application of the actual investment condition and finally the whole system operation results show that the control system is to achieve the control goals. Automatic combustion control system of machinery this paper describes the design and implementation of chain grate furnace, has been applied in Zhejiang city of Ningbo province. The system has been put into operation, the grate control system is running well, simple operation The automatic combustion control system of garbage machine burning grate stove runs well, the speed of regulation is fast, the stability of the system is good, and the ability of resisting interference is strong, which achieves very good results.
