PURPOSE: A venturi nozzle for a filtering dust collector is provided to stably separate dust from filtering fabric by spraying primary compressed air and secondary air from a second venture nozzle. CONSTITUTION: A gas inlet introduces gas containing dust. A dust discharging hole(3) is installed to the lower vertical direction and discharges dust. A gas discharging hole(4) discharges purified air without dust. A porous plate(5) is fixed on the internal upper part of a dust collector body(1). A plurality of filtering fabrics(6) is to the lower vertical direction of the porous plate and collects dust. A duct(7) transfers the purified air without dust to the upper side. A blow tube(8) transfers compressed air by being installed at the upper side of the porous plate. A first venturi nozzle(9) sprays compressed air. A second venturi nozzle is installed on the porous plate.
