An air filtering device with a high-voltage power transmission line support comprises filtering paper (9), a filtering frame (1), a net base (4), ion filaments (2) disposed below the filtering paper, and a discharge net (5) disposed below the ion filaments. The ion filaments are mounted on an ion filament component (3), and the ion filament component is made of a net-shaped insulation material and is fixed in the net base. The filtering paper is fixed in the filtering frame, and the filtering frame fits and is connected to the net base. A ceramic insulation column (6) is disposed on the discharge net, a top end of the ceramic insulation column is connected to the ion filament component, and the ceramic insulation column is a hollow through cavity. A high-voltage connecting wire (63) of the ion filaments penetrates a cavity of the ceramic insulation column. Because the periphery of the discharge net does not contact the net base but is connected under the ion filament component through the ceramic insulation column, high-voltage electricity strikes arc nowhere and the security of the air filtering device in a use process is improved. |
