The invention discloses electric automation dedusting equipment. The electric automation dedusting equipment comprises a cylinder, a first fan, a corona electrode, a motor, a dust collection electrode, a conductive piece, a brush, a second fan and an activated carbon plate. The electric automation dedusting equipment has the advantages that by arranging the cylinder, the motor, a power source, thecorona electrode, the conductive piece and the dust collection electrode, an output shaft of the motor drives the dust collection electrode to rotate through a connecting rod; when the dust collection electrode is moved to touch the conductive piece at the right side wall of the cylinder, the dust is moved to the dust collection electrode and is adsorbed to the surface of the dust collection electrode; when the dust collection electrode adsorbing the dust continues to move to the left side of the cylinder and disengage from the conductive piece, the dust collection electrode is deenergized, the dust falls down and falls into a dust collection box through a dust discharge pipe, and the dust is removed by static electricity, so that the purifying efficiency is high, and the gas treatment range is large; the dust on the dust collection electrode is brushed off by the brush, so as to avoid the influence to the dedusting effect and the service life of the equipment due to accumulation of dust on the dust collection electrode along with the dedusting operation of the building; the dust can be automatically collected, and the working efficiency is high.
