摘　　要：分析国内电除尘器相关标准对本体压力降和本体漏风率的规定,从环保指标、性能指标和管理指标评价电除尘器。为有效控制烟(粉)尘污染,应使粉尘出口浓度降低至环保要求排放限值以下,建立在线监测系统,降低本体压力降和漏风率,提高除尘效率、系统投运率和产品零部件标准化系数。概述湿式静电除尘和电袋复合除尘器两种新型除尘技术,并建议今后的研究内容包括以下方面:通过调整烟气温度、湿度或添加其他化学物质的方法调整粉尘比电阻;选择合适的电极形式并使用宽间距、合理设置导流装置和经常检查运行设备以补救漏风问题;根据运行的实际情况,选择合适的供电系统和清灰系统。The domestic standards for electrostatic precipitator about pressure drop and leakage rate were analyzed. The electrostatic precipitator was evaluated from three aspects,including environment protection, performance and management. In order to effectively control the dust emission,the outlet dust concentra-tion should be reduced below the standard emission limit. The on-line monitoring system was established, body pressure drop and leakage rate was degraded,and the removal efficiency and system operation rate and the product components standardized coefficient was enhanced. The new electrostatic precipitator technologies,including wet electrostatic precipitator and electrical bags composite,were demonstrated. The future research direction for electrostatic precipitator was discussed,including adjustment of dust specific electric resistance by means of adjusting the temperature and humidity of flue gas,adding other chemical substances,selecting appropriate form of electrode and wide spacing,setting reasonable flow guide device, and checking regularly the operating equipment in order to solve the problem of air leakage. According to the practical operation,suitable power supply system and dedusting system will be adopting.
