Efficient energy-saving type electric dust removing device

The invention discloses an efficient energy-saving type electric dust removing device which comprises cathode wires, cathode frameworks and anode plates. A plurality of cathode frameworks and a plurality of anode plates are arranged in parallel and in an alternating manner. A plurality of cathode wires are arranged in each cathode framework. Each cathode framework comprises a cross beam. The crossbeams of the cathode frameworks in two adjacent rows are not located on the same horizontal plane. Each cathode wire comprises a supporting pipe and a barb. The top end of each barb is provided witha front tip end and a rear tip end. The distance between each front tip end and the corresponding rear tip end is larger than the maximum distance between the front and the rear of each supporting pipe. The anode plates comprise a plurality of anode plate bodies. A collecting groove is formed in the right of each anode plate body, and a limiting edge is arranged on the left of each anode plate body. The electric dust remov
