The filter element frame is easy to install and maintain; the quality of the frame directly affects the filtration status and service life of the filter bag. The electrostatic precipitator accessories utilize a high-voltage direct current electric field to charge the dust particles in the dusty gas. Under the action of the electric field force, the charged particles settle on the surface of the sedimentation electrode, and then, under the impact of the vibration force, the sheet-like dust falls into the device.
