Patent attributes
An aspect of embodiments of the invention is to lower fluid resistance applied to gas flow (A, S) flowing within a dust collection system (1) so as to enhance dust collection efficiency of the dust collection system (1) without depending on the number or the two dimensional arrangement of movable elements (40) within the system (1). Embodiments of the dust collection system (1) of the invention includes: a housing (10) defining a cavity (50) therewithin, the housing (10) having a plurality of inlets (53) and at least one outlet (57) for gas; a plurality of movable elements (40) for opening and closing the inlets (53), the movable elements (40) being respectively provided corresponding to each of the inlets (53); a gas flow generating device (20) for generating a gas flow (A, S) from each of the inlets (53) to the outlet (57) during the opening operation of the movable elements (40); and a flow path control device (13) for controlling the flow paths of the gas flow (A, S).
