PURPOSE:To provide a plasma reaction vessel for a nitrogen oxide decomposition device by which high decomposition efficiency is realized at low cost without using large-scale equipment and power and which is put to a practical use as a waste gas antipollution measure device used in various combustion devices discharging a lot of waste gas. CONSTITUTION:A waste gas passage 2 where waste gas contg. nitrogen oxide NOx flows is installed in a plasma reaction vessel 1. In the passage 2, net electrodes 4, 5 for generating discharge plasma to decompose nitrogen oxide NOx in the waste gas are arranged. Between the electrodes 4, 5, dielectrics 6 which are nearly spherical particulates and have photocatalytic action are piled up. When high voltage is impressed to the electrodes 4, 5, discharge plasma and photocatalytic reaction by its luminous light occur in the clearance between particles of the dielectrics 6 to decompose the nitrogen oxide NOx in the exhaust gas. |
