As shown, the electrostatic precipitator 2 includes a plurality of cathode lines 21; each cathode line 21 is surrounded by one anode tube 22, the anode tubes 22 are arranged side by side to form a honeycomb-shaped structure, and the section of each anode tube 22 is hexagonal or square; the anode tube 22 is made of glass fiber cloth 221, and conductive carbon fibers 222 are provided in the glass fiber cloth 221 along the longitudinal direction of the anode tube 22. In a preferred embodiment, the diameter of the inscribed circle of the cross section of the anode tube 22 is between 300 and 450mm, and the longitudinal length of the anode tube 22 is between 4 and 9 meters.
In a preferred embodiment, the conductive carbon fibers 222 are uniformly arranged along the circumference of the anode tube 22, so that a uniform electrostatic field is formed between the anode tube 22 and the cathode line 21. In another preferred embodiment, the cross section of each cathode line 21 is i-shaped, and the cathode lines 21 can be twisted into a twist shape along the length direction thereof, and experiments show that the cathode lines 21 with the i-shaped cross section can obtain a 360-degree discharge effect, and meanwhile, compared with cathode lines with other cross sections, the cathode lines have much stronger structural strength and are not easy to swing in high-speed airflow to cause unstable voltage.
In another embodiment shown in fig. 3, specifically showing the connection structure of the cathode wires 21, as shown in the figure, the upper ends of the plurality of cathode wires 21 are bound to the upper part of the tower body 1, the lower ends of the plurality of cathode wires 21 are uniformly connected to a weight frame 23, the periphery of the weight frame 23 is connected with a plurality of tension wires 24, and the tension wires 24 are bound to the lower part of the tower body 1 through insulators 25.
