The present invention discloses a microparticle purification device based on an electrostatic agglomeration technology. The device comprises a pre-charge device configured to allow microparticles to absorb charges of different polarity, and an electrostatic agglomeration device configured to generate an alternating electric field to allow the microparticles with the charges of different polarity to mutually impact and to be coagulated. In the airflow flow path, the pre-charge device is located at the upstream of the electrostatic agglomeration device, the pre-charge device comprises pre-chargepolar plates and tungsten filaments, each pre-charge polar plate comprises a first polar plate unit and a second polar plate unit, in the airflow flow path, the first polar plates are located at theupstream of the second polar plates, the first polar plate units define opening first spaces, the second polar plate units define opening second spaces, the first space and the second space in the same polar plate are separate
