Abstract
The invention discloses a strip cathode wire for an electrostatic dust collector. The strip cathode wire comprises a cathode pole (1), wherein a strip discharge rack (2) is arranged on the cathode pole (1), and is arranged in the length direction of the cathode pole (1); and angular discharge tips (3) are arranged on the discharge rack (2) at intervals. The strip discharge rack is arranged on the cathode pole in the length direction of the cathode pole, and the number of the discharge rack and the structure and number of the discharge tips on the discharge rack are limited, so that the electrostatic dust collector using the cathode wire has the characteristics of low corona onset voltage and high discharge current; and meanwhile, as the set mode of the discharge rack enables dust captured by the cathode wire to be difficultly bonded and conveniently cleaned, the problems of easy bonding of the captured dust on the cathode wire in a corona dead area and difficult cleanness in an original electrostatic dust collector are preferably solved, and the dust and mist removing efficiency of the electrostatic dust collector is further improved.
