Abstract: This paper analyzes the necessity and application of ESP in environmental protection in our country, briefly introduces ESP research status at home and abroad, pointing out challenges and current main problems of technical aspects facing by ESP application. From summing up a large number of foreign researches, it is pointed out that the most important factor of impacting ESP is dust cohesive force. The idea of adjusting the cohesive force between polar plate and dust is put forwards from the perspective of dust polarization theory and polar plate electronic work function. According to theoretical study above, the latest research that selects a coating used in cohesive force surface to adjust dust cohesive force is proposed.

Key words: ESP, Dust, Cohesive force, Polar plate
