The invention solves the problems of power failure, reduced efficiency of the electric dust collector 100 and over-standard discharge at the outlet when each electric field high-voltage power supply of the electric dust collector 100 independently supplies power.

In a third aspect, the present invention further provides a power supply method applied to the adjacent electric field mutual redundancy power supply system of the electric dust collector in the second aspect, including:

when detecting that the first electric field power supply and the second electric field power supply of the first filtering component 4 and the second filtering component 5 are normal, controlling the first electric field power supply and the second electric field power supply to independently supply power to the first filtering component 4 and the second filtering component 5 respectively;

when a first electric field power supply fault of the first filter assembly 4 is detected, controlling a second electric field power supply to simultaneously supply power to the first filter assembly 4 and the second filter assembly 5;

and when the second electric field power supply of the second filter assembly 5 is detected to be failed, controlling the first electric field power supply to simultaneously supply power to the first filter assembly 4 and the second filter assembly 5.

For a detailed description, please refer to the second aspect, which is not described herein.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
