<p>An exhaust gas treatment system is provided to increase the treatment volume of the exhaust gas by increasing the diameter of the reaction tube, and to improve the harm removing performance by stabilizing the state of generation of plasma without requiring a water membrane, thereby extending the plasma length. An exhaust gas treatment system comprises: a reaction tube(1) for introducing exhaust gas(G); an upper electrode(2) installed in the air above the reaction tube; a lower electrode(3) installed under the reaction tube; and a spray nozzle(4) for spraying an electrolyte solution(D) between the upper electrode and the lower electrode to generate plasma(P) in the reaction tube by spraying the electrolyte solution between the upper and lower electrodes, thereby forming a path of electric current between the electrodes. The exhaust gas treatment system further comprises: a water-cooling jacket(11) installed around the reaction tube to cool the reaction tube during the generation of plasma and clean the reaction tube by overflowing water(H) in it during stopping of the plasma; and a power supply unit(5) from which a high-voltage current is applied to the upper electrode. The water of the water-cooling jacket is introduced from the bottom part of the water-cooling jacket, flows from an overflow line(12) into a water tank(6), and is discharged from an overflow line(62) during the generation of plasma. The reaction tube is cleaned by closing a valve(13) of the overflow line(12) during stopping of the plasma, thereby overflowing the water in the reaction tube.</p> |
