Exhaust gas treatment apparatus

摘要

An exhaust gas treatment apparatus 1a of the present invention includes: a tubular body 10, a discharge electrode 12 disposed inside the tubular body 10, and a stick-shaped dust collection electrode 14. The number of the particulates 22 suspended in the exhaust gas 20 is decreased by charging the particulate matter 22 contained in the exhaust gas passing through the tubular body 10 by corona discharge 24 caused by the discharge electrode 12, collecting the charged particulate matter 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 particulate matter 22a, and allowing the agglomerated particulate matter 22b to scatter again.
