摘要
湿式电除尘器因受自身条件限制,存在极板表面水膜均匀性差、电晕闭塞、极板腐蚀、耗水量大、运行费用高、可靠性低、效率衰减等问题。文章结合实践,分析了湿式电除尘器的技术特点及常见问题,指出湿式电除尘器并不是当前燃煤电厂实现超低排放唯一的最佳技术选择。
The wet electrostatic precipitator exists many problems, such as poor equality of surface water membrane ofpole board, corona obstruction, erosion of pole board, great quantity of water consumption, high operation costs, low reliabilityand efficiency attenuation. The paper analyzes the technical characteristic of wet electrostatic precipitator and problems to beconcerned. The paper points out that wet electrostatic precipitator is not the one and only best technical choice that realizes theultra low emission in coal-fired power plant.
