The working principle of the device is that smoke dust of smoke is positively charged when the smoke passes through a flue in front of a main structure of the electric dust remover, and then the smoke enters an electric dust remover channel provided with a plurality of layers of cathode plates. The positive charge smoke dust and the cathode electric plate are adsorbed mutually, so that the particle smoke dust in the smoke gas is adsorbed on the cathode, and the cathode plate is struck regularly, so that the smoke dust with certain thickness falls down in an ash hopper below the electric dust collector structure under the double actions of self weight and vibration, and the purpose of removing the smoke dust in the smoke gas is achieved.
The conventional electrostatic precipitator generally adopts a plurality of electric fields connected in series to improve the dust removal efficiency, but in the circulating space close to the airflow outlet of the electric fields, mutually repulsive charged dust and insufficiently charged dust are easy to escape from the electric fields. In addition, the electrostatic dust collector is easy to form secondary dust during the process of rapping for dust removal, and the part of dust is easy to escape from an electric field.
