The utility model discloses a high efficiency electrostatic smoke prevention dust remover, composed of a shell body, a dust collection plate, a discharge electrode, bur, an oblique wind-protection plate, an ash bucket, etc. The utility model is characterized in that an inlet of an ash discharging passage formed by the end head of the oblique wind-protection plate and the tail end of the dust collection plate faces the direction of motion of airflow, and the bur on the discharge electrode vertically points to the surface of the dust collection plate. With simple structure, the utility model effectively overcomes the phenomenon of the rebound of low specific resistance powder dust on the surface of the dust collection plate and the newly flying of small powder dust. Compared with the general electric dust remover, the utility model can reduce manufacturing cost and running cost to 50%.
