PURPOSE: A dust collecting apparatus is provided to standardize the flow rate of dust containing air by suppressing the maximum speed of the air at a center part with respect to the horizontal direction of a baffle plate. CONSTITUTION: A dust collecting apparatus(1) includes a duct chamber(100), a filtering chamber(200), a baffle plate(300). The duct chamber includes the introducing hole(110) of dust containing air. The filtering chamber includes filters(210) filtering the dust containing air. The baffle plate includes a plurality of perforated holes. The dust containing air flows from the upper side to the lower side of the duct chamber and is introduced into a direction along the baffle plate. The dust containing air passes through the perforated holes to be introduced into the filtering chamber. A non-perforated bad parts(306A, 306B) are formed along the vertical direction at a center part with respect to the horizontal direction of the baffle plate. |
