Description of the Related Art In a conventional wet type electrostatic precipitator, as shown in FIG. 12, a precipitating electrode 1 is vertically fixed by a precipitating electrode fixing bracket 2, and a discharge electrode 3 is interposed between the precipitating electrodes 1 in an insulator chamber. It is arranged vertically lower than the supporting insulator 5 in 4 and forms a dust collecting space. The dust collecting electrode 1 has a thickness of about 1 to 2 mm and has rigidity in the vertical direction.
, A square (b), a triangle (c), and the like. The dust collecting electrode 1 is fixed vertically with the dust collecting electrode fixing brackets 2 attached to both sides and tightened with bolts 6 and nuts 6A. A spray nozzle chamber 7 is provided above the dust collection space, and a header portion having a nozzle 8 attached thereto is disposed in the chamber. The water sprayed from the nozzle 8 by the cleaning spray 8A flows downward while forming a water film 8B on the surface of the dust collecting electrode 1, falls into the hopper 9, and is discharged by the discharge device 10. When a negative DC high voltage is applied to the discharge electrode 3, a negative ion current starts to flow (corona discharge) from the discharge electrode 3 toward the dust collection electrode 1 (positive ground electrode) through the dust collection space. When dust and mist (particles) contained in the processing gas are introduced, the particles are charged by negative ions, and the particles attracted to the surface of the dust collecting electrode 1 by the electric field are washed down together with the water film. If the water film is not formed, the dust collected on the dust collecting electrode accumulates, so that the interval between the high voltage electrode and the ground electrode becomes narrow, sparks frequently occur, and the dust collecting performance deteriorates.
