湿式电除尘器在燃煤电厂的应用条件分析

Study on Application Conditions of Wet Electrostatic Precipitators in Coal-Fired Power Plants

湿式电除尘器近年来在中国燃煤电厂急速发展,然而业内对其普遍认识不足,更缺乏实践经验,因此有必要借鉴国外经验,对其应用条件及设备选型进行探讨。通过对国内、外湿式电除尘器在燃煤电厂的应用研究,对湿式电除尘器技术的发展、应用情况进行了分析,阐述了湿式电除尘器在烟气处理系统所处的地位,提出了湿式电除尘器应用条件建议。

In recent years, wet electrostatic precipitators （WESPs） have been rapidly developed in China. Due to the lack of the common understandings about WESP in the industries and practical experience, it is necessary to explore the application conditions and equipment selection of WESP by learning from the foreign experience. Based on the investigation of WESPs in domestic and foreign coal-fired power plants, the development and application of WESPs are analyzed comprehensively, and the importance of WESP in the entire flue gas treatment system is presented. Finally, some suggestions on the application conditions of WESPs are put forward.
