US 8,877,134 B2 · Exhaust gas treating system

Abstract

The present invention, aiming at providing an exhaust gas treating system capable of increasing the exhaust gas treating volume, through increase of the diameter of the reaction tube, stabilizing the state of generation of plasma without requiring any water membrane, and improving the harmful matters removing performance by extending the plasma length, comprises a reaction tube 1 for introducing exhaust gas G, an upper electrode 2 disposed in the air on the top side of the reaction tube 1, a lower electrode 3 disposed on the bottom side of the reaction tube 1, and a spray nozzle 4 for spraying an electrolytic solution D between the upper electrode 2 and the lower electrode 3, so as to form a path of electric current between the electrodes 2, 3 and generate plasma P in the reaction tube 1, by spraying an electrolytic solution D between the upper electrode 2 and the lower electrode 3.
