Apparatus for removing contaminated material

An apparatus for removing a contaminated material, the apparatus comprising:

• a housing having a central column, a first duct and a second duct;
• a plurality of partition walls being slantly installed within the housing, a first plurality of partition walls extending from an inner surface of a sidewall of the housing toward the central column while a second plurality of partition walls extending from the central column radially outward toward the inner surface of the housing, and the first and the second plurality of partition walls being alternately arranged so as to form a zigzag channel through the housing which defines a zigzag air path for an exhaust gas flowing through the apparatus from the fist duct to the second duct;
• an adsorbent discharging unit installed inside the housing to discharge an adsorbent into the zigzag air path as the exhaust gas flows through the housing;
• and
• an impact apparatus configured to apply an impact force to the housing so as to cause the contaminated material, which collects on a surface of the first and the second plurality of partition walls, to fall by gravity toward a bottom of the housing;
• wherein the adsorbent is introduced into the zigzag channel, formed by the first and the second plurality of partition walls, such that the adsorbent flows together with the exhaust gas, as the exhaust gas flows along the zigzag air path, for collecting and removing the contaminated material from the exhaust gas.
