Abstract： In view of the the problems caused by the treatment of wet flue gas dust in coal-fired power plants by using the wet electrostatic precipitator （WESP）， the characteristics of using the FRP material as the breakthrough point and using the new type of anode material as the breakthrough point are expounded in this paper. In order to meet the special needs of anode materials， the high conductivity composite material SDD-CF was developed using special process formula. A wet electrostatic precipitator based on SDD-CF， a new high conductivity composite anode material， was successfully developed. The problems of easy corrosion， difficult anticorrosion and short life of wet flue gas dust remover are solved， and the whole structure of wet electrostatic precipitator is optimized by using the particularity of high conductivity composite anode material SDD-CF. Many problems have been solved， such as escape of wet flue gas， the existence of flue gas corridor in electric field， the existence of corona blind area， the large amount of water washed by wet electric precipitator and the production of secondary wastewater and so on. This result has been successfully applied to a certain power plant"s #1 and #2 units in 2014 wet electric dust removal technology transformation project， the project was completed and put into production in that year and passed environmental acceptance. After the project was put into operation， the operation is stable， energy saving， environmental protection and social benefits are obvious. The achievement， as appraised by the China Electrical Engineering Association on August 17， 2017， has reached the international advanced level， among which， it is the international leader in the research and development and application of new anode materials. The project was awarded the first prize for scientific and technological innovation by the State Energy Group in 2018.
