Abstract: An electrostatic precipitation module includes a plurality of conductive precipitation electrode plates and a plurality of non-precipitation electrode plates. The plurality of precipitation electrode plates are interlacedly distributed along the length of a first connecting rib; the precipitation electrode plates are made from conductive plastic material by injection molding, and a metal conductor is embedded inside the first connecting rib by in-mold injection molding, so that a precipitation electrode plate module is formed; a non-precipitation electrode plate module is formed with a similar structure. After the precipitation electrode plate module and the non-precipitation electrode plate module are assembled, the precipitation electrode plates and the non-precipitation electrode plates form an electrostatic precipitation module.
