Electric dust remover with porous dust collection electrodes, and electric dust removal method

The invention discloses an electric dust remover with porous dust collection electrodes, and an electric dust removal method. Porous dust collection polar plates of the electric dust remover with the porous dust collection electrodes are fixedly arranged in the inner cavity of a shell, and the multiple porous dust collection polar plates are parallel to one another and arranged at intervals; a flue gas inlet and a flue gas outlet are respectively formed in two ends of the porous dust collection polar plates on the shell, and each porous dust collection polar plate is connected with an ash removal rapping device; each discharge wire is connected with the ash removal rapping device; a plurality of discharge wires are arranged between the adjacent porous dust collection polar plates at intervals; the thickness of the porous dust collection polar plate is 40-60 mm, a plurality of circular through holes are uniformly formed in the porous dust collection polar plate, and the aperture of each circular through hole i
