电除尘高压电源控制系统的研究
|
摘要
电除尘器作为一种广泛应用于水泥、电力、冶金、建材等行业的环保装置,投入工业以来为大气污染的治理和生态环境的保护做出了重要的贡献。随着人们的环保意识日益加强,以及国家对环保排放标准的严格要求,需要进一步提高电除尘器的性能、降低粉尘排放浓度。因此,研究开发电除尘供电控制系统对于提高电除尘器的除尘效率具有重要意义。
本课题的主要工作是开发以微机控制器为核心的高压供电控制系统,其设计不仅适用于电除尘器高压电源控制系统的改造,也适用于不同行业和工况的电除尘控制系统上。论文简述了电除尘器的组成和静电除尘的基本工作原理,讨论了供电系统的电气参数、火花放电与除尘效率的关系,分析了供电控制系统设计中的技术难点以及关键点。本文提出了针对电场复杂工况的多种有效控制模式,完成了高压供电控制硬件系统和软件系统的设计,详细叙述了在设计与调试中应该注意的问题和具体的解决方法。高压供电控制系统不仅具有常规的控制方式与检测功能,还能够自动跟踪最高运行电压,特别工况复杂多变,控制精度要求高的场合,微机控制器通过精确的火花控制,显著地提高电除尘器的电晕功率。此外,系统还对电场短路、电场开路、偏励磁等故障设计了完善的保护功能。论文的另外一个重要组成部分是大量的现场实验,在实验中不仅验证了电除尘方案可行性,而且使我对电除尘的工艺有了更深入的了解。
The electrostatic precipitator is extensively a kind of environmental protection device which is applied in professions, such as cement, electric power, metallurgy and building materials, besides which, the devotion is industrial was the protection of air pollution and ecosystem environment to make important contribution. Strengthen increasingly along with the people's environmental protection consciousness; further request of nation to environmental protection exhaustion standard. Therefore, using the research of the power supply system of electrostatic precipitator to enhance the dust efficiency has important meaning.
This thesis mainly takes microcomputer as the high voltage power supply of core to control system. Its design is not only applicable to high voltage controls system's reformation of electrostatic precipitator, but also being applicable to different profession and work condition of this control system. The thesis summarizes the constitution and the basic principle of electrostatic precipitator, in addition to discuss the connection between the electricity parameter, spark and dust efficiency of high voltage power supply system, analyzes power supply's technique crux within system design and the key. The problems and resolve methods those should notice in the design and debugging describe in detail. The high voltage control systems not only have the regular function of controlling and checking, but also can track the highest running power pressure automatically, especially in the occasion of complex and high precious condition; the computer controller can increase the faint power dramatically by controlling the spark preciously. And still have many perfect protection functions as the short circuit of electric field, the open circuit of electric field, imbalance and the oil temperature super limitation. Another important constitution of the thesis is a great deal of electric field experiments which can validate the feasibility of the electrostatic de -dusting and give me a more deep understanding of this technical.
