This paper first reviews the achievements made in the experimental research, development and application of the electrostatic precipitator in the domestic steel industry, analyzes the factors that affect the dust removal efficiency of the electrostatic precipitator in the operation of the ESP in the current steel industry, and the reasons for these problems . Combining with the above analysis, some measures to improve the long-term efficiency and stable operation of electrostatic precipitator are put forward, including the flue gas conditioning combined with dust removal process, the design of suitable dust collection area and the manufacture and installation of ESP. Finally, it emphasizes the importance of daily operation and management of electrostatic precipitator to ensure its stable and efficient dust removal. The prospect of ESP technology development in iron and steel enterprises is also forecasted.
