A cyclone type bag-filter dust collector is provided to remove effectively dust generated when a filter bag is cleaned, by making the dust smoothly fall in a cyclone through a venturi. A funnel-shaped venturi(30) is installed on an inside of an outer cylinder(6). A cyclone(20) is disposed below the venture, wherein the cyclone has an air inflow port. A filter bag(5) is disposed above the cyclone to remove dust. The venturi includes an air inflow tube(40) and lift plates(50). Air within the cyclone is moved to a bag-filter room(10) via the air inflow tube. The lift plates are fixed to an upper side of the air inflow tube, and air passages are formed between neighboring lift plates. The lift plates are fixed to the inside of the outer cylinder while the lift plates become wide toward the outside.
