A water spray mechanism 53 is provided between the two groups of electrode dust collecting plates 51, and one end of the water spray mechanism 53 is rotatably matched with the circulation component 2.

[0031] In this embodiment, the water spraying mechanism 53 includes a water pipe 11, a connecting pipe 12, a nozzle 13, a semi-toothed wheel 14, a rack 15, a slide 16 and a cylinder 17. One end of the water pipe 11 is connected to the connecting pipe 12 that rotates with the circulation component 2. A plurality of nozzles 13 are arranged in an array at the bottom of the water pipe 11. The other end of the water pipe 11 is rotatably matched with the semi-toothed wheel 14 through a rotating shaft.

With the help of the gear meshing between the rack 15 and the semi-toothed wheel 14, the semi-toothed wheel 14 can be driven to rotate, thereby driving the water pipe 11 and the nozzle 13 connected to the semi-toothed wheel 14 to rotate together.

[0033] In this embodiment, the dust removal device 52 includes a ball screw 21, a telescopic cover 22, a rectangular plate 23, a through hole 24 and a cleaning brush 25.
