The inner wall of the silencer chamber 18 is provided with a plurality of silencer grooves 19. The noise generated by the electrostatic dust removal device 6 during operation will enter the silencer chamber 18 through a plurality of through holes 17. The noise passes through the silencer grooves 19 in the silencer chamber 18, so that the noise can be continuously reflected in the silencer chamber 18, thereby consuming the noise capacity and achieving the effect of noise reduction. In addition, the outer sound insulation board 20 is used for secondary noise reduction. The running electrostatic dust removal device 6 is buffered and vibration-reduced by the provided vibration-reducing components, so as to reduce the noise generated by the vibration of the electrostatic dust removal device 6 during operation. Furthermore, the noise is reduced by the silencer chamber 18 and the sound insulation board 20, so as to improve the noise reduction effect on the electrostatic dust removal device 6. The vibration-reducing components are of an integral structure, which is convenient for replacement in cooperation with the supporting components.

At this time, the clamping plate 8 can be directly taken out, so that the spring damper 11 is moved out with the two clamping plates 8, and then the clamping plates 8 on both sides of the new vibration damping component are clamped into the two limiting clamping seats 7, and the connecting bolts 9 are screwed into the clamping plates 8 to complete the replacement of the vibration damping component.
