Conveyor electrostatic duct collection apparatus which mainly comprises an insulator device and a direct-current high-voltage transformer device arranged on a dust collection casing base and an electrostatic dust collection device arranged in the dust collection casing base

The present invention relates to a conveyor electrostatic dust collection apparatus, which mainly comprises an insulator device and a direct-current high-voltage transformer device arranged on a dust collection casing base and an electrostatic dust collection device arranged in the dust collection casing base and in electrical connection with the direct-current high-voltage transformer device. The insulator device comprises a plurality of insulator structures that includes an insulation barrel and a heating assembly. The insulation barrel forms a sealed space inside a mounting casing portion of the dust collection casing. A support frame of the electrostatic dust collection device extends into the sealed space and is provided for mounting multiple electrostatic dust collection poles. Each electrostatic dust collection pole includes first pole needles and a plurality of second pole needles having different installation angles. A length of the second pole needles is greater than a length of the first pole needl
