煤电机组超低排放烟尘控制集成技术分析

Analysis on Integrated Technology of Ultra-low Emission Soot Control of Coal-fired Power Units

煤电机组烟尘超低排放的改造是我国降低大气污染物排放总量的重要措施,但相关技术改造难度大、风险大,改造效果不易实现。本文全面介绍了常用除尘技术的基本特征,同时提出湿电除尘器的应用频率及更新技术的相关意见,并系统地阐述了各个装置在设计、制造、应用及监控等方面需要注意的细节。

The transformation of ultra-low soot emission of coal-fired power units is an important measure to reduce the total emission of air pollutants in China, but the relevant technical transformation is difficult and risky, and the transformation effect is not easy to achieve. In this paper, the characteristics of common dust removal technologies are described in detail, the technical suggestions on the application frequency and renewal of wet electrostatic precipitator, and the precautions of each device in design, manufacturing,construction, operation and monitoring are systematically described.
