ELECTROSTATIC PRECIPITATOR

摘要

The present invention relates to an electric dust collector comprising: a plurality of discharge members (20) which are installed in a dust collection chamber (10) having an insertion hole (12) and a discharge hole (14) and charge fine particles to have negative polarity; and a plurality of dust collection disks (30) which are arranged between the discharge members (20), rotate with a driving shaft (32), and have positive polarity to collect the charged fine particles. The dust collection disks (30) have shaft holes (31) to be joined to the driving shaft (32) in a loose-fitting manner, receive driving force by key (34) joining, and are arranged at intervals as the dust collection disks are inserted into incised grooves (42) of a plate (40). Therefore, precision for an initial assembling process and a dust collection disk replacement process is increased regardless of skill of a worker as the dust collection disks are coupled to the driving shaft in a loose-fitting manner and are arranged at intervals while being inserted into the incised grooves of the support plate.
