高频双区组合技术在电除尘器改造上的应用

摘要

介绍了广东某电厂一期1×300MW机组电除尘器因受场地限制，采用“高频双区组合技术”进行改造，改造后的除尘效率由99%(设计)提高到99.9%以上，为国内同类设备的提效改造提供了成功经验.%　　The paper introduces a renovation & modifcation project, Guangdong of 1×300MW thermal power plant phase-I. As the limited space, the advanced combined technology of high-frequency power supply & double-stage ESP is adopted and the rate of dust removal is increased from 99% up to 99.9%, which provides the excellent and successful experiences for R&M of other similar power plants in the country.
