摘要
传统的除尘方式难以控制工业微细粉尘的排放,是引起我国多数城市空气环境质量超过PM2.5排放标准的主要因素之一。在分析常规除尘器存在问题与微细粉尘荷电捕集机理的基础上,提出前置烟道放置电凝并器、前级电场电极优化配置、末级电场采用转动极板、配套使用高频电源或脉冲电源的治理方案,是有效捕集工业微细粉尘的重要手段。同时,还分析了影响电收尘效率的关键因素以及应该采取的措施,为研发新一代静电除尘器提供理论指导。
The traditional dedusting way is very difficult to control industrial fine dust emission, which is one of the main factors to cause air environment quality below the requirements of new PM2.5 emission regulations in most cities in China.Based on the analysis of conventional precipitator defects and fine dust charge trapping mechanism, a new electrostatic dust removal scheme was put forward, which could integrate with coagulation in the flue, optimum electrode configuration at front fields ,rotating polar plate at last field, good matched high-frequency power or pulse power and etc. , that is the important means of effective trapping industrial fine dusts. In addition, the factors influencing collection efficiency were analyzed and the measures should be taken so as to provide theoretical guidance to develop a new generation of electrostatic precipitator.
