To this end, an apparatus for pretreating an exhaust gas for removing particulate matter having a transport path changing member for exhaust gas includes a particulate matter removing unit in addition to the duct 10 described above.

The duct (10) is provided for providing the path of the exhaust gas.

Specifically, the duct 10 is a threaded joint having a female thread at both ends, and can be connected to a coupling 11 used to connect two pipes of the same diameter.

The particulate matter removing unit includes a screw 100, a filter 200, a feed path changing unit 300, and a jetting unit 400 provided in the duct 10 to remove particulate matter contained in the exhaust gas.

The screw 100 is rotated so that the particulate matter flows in the direction of the inner surface of the duct 10 by the generated centrifugal force.

Specifically, the screw 100 is provided at one end of the duct 10 so as to rotate, thereby generating a centrifugal force. When the centrifugal force is generated, the exhaust gas flowing due to the centrifugal force generated is swirled, So that the particulate matter contained in the duct 10 can flow toward the inner surface of the duct 10.

The filter 200 is provided for filtering the particulate matter flowing in the direction of the inner surface of the duct 10 by the screw 100.

Specifically, the filter 200 is provided at the other end of the duct 10 in a truncated cone shape in which the diameter of the circumference increases along the conveyance direction of the exhaust gas so that the filtration area of the particulate matter flowing in the direction of the inner surface of the duct 10 is increased , The particulate matter flowing in the direction of the inner surface of the duct 10 can be filtered.

Further, the filter 200 may be provided so that the parallel plane of the truncated cone is opened to reduce the swing pressure drop.
