<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment apparatus capable of decreasing the number of particulates contained in exhaust gas by agglomerating the particulates contained in the exhaust gas. <P>SOLUTION: The exhaust gas treatment apparatus 1a includes a tubular body 10, a discharge electrode 12 disposed inside the tubular body 10, and a stick-shaped dust collection electrode 14 disposed over the range of a length of twice or more the inner diameter of the tubular body 10 along the central axial direction of a flow passage on a downstream side of the discharge electrode 12. The number of the particulates 22 suspended in the exhaust gas 20 is decreased by charging the particulates 22 contained in the exhaust gas passing inside the tubular body 10 by corona discharge 24 caused by the discharge electrode 12, collecting the charged particulates 22a on the inner wall face 10a of the tubular body 10 by the electric field 26 generated by the dust collection electrode 14 to agglomerate the plurality of particulates 22a, and allowing the agglomerated particulates 22b to scatter again. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
