Disclosed is an electrical dust collecting apparatus which includes a dust collecting unit formed of an air pipe and realizes the optimal air spray mechanism through air flow analysis. The electrical dust collecting apparatus includes a dust collecting module, a ventilation module, a connection unit, a power module, and an air spray pipe. The dust collecting module includes a dust collecting plate to ionize sucked dust and to adsorb the ionized dust. The ventilation module allows external air to be sucked into the dust collecting module. The connection unit connects the dust collecting module with the ventilation module through an electrical signal. The power module generates high voltage such that the ionization and the dust collection function can be performed, supplies the high voltage to the dust collecting module and supplies driving power to the ventilation module. The air spray pipe includes a plurality of spray holes to spray air toward the dust collecting plate through the spray holes. The spray holes are spaced apart from each other by a predetermined distance in a longitudinal direction of the air spray pipe, and the diameter of each spray hole is in the range of 1.8 mm to 2.8 mm. Accordingly, air can be effectively discharged, so that high dust collection performance can be continuously represented. In addition, dust can be uniformly removed by optimizing the number and the size of the spray holes. |
