EXHAUST GAS TREATMENT AND EQUIPMENT THEREFOR

摘要

PURPOSE:To provide a method and a device for treating exhaust gas capable of removing NOX and SOX in large volume of exhaust gas with high efficiency. CONSTITUTION:Exhaust gas is introduced into a plasma reaction vessel 7 through a exhaust pipe 6, while, on the other hand, ammonia is fed to and mixed with the exhaust gas from an ammonia supply device 8 through a supply pipe 9 connected to an inlet pipe 10 of the plasma reaction vessel 7. A power source 11 applies plasma generating power to the electrode of the plasma reaction vessel 7 and the exhaust gas is transferred from an outlet pipe 12 connected to the plasma reaction vessel 7 to a dust collector 13 for removing and recovering ammonium nitrate and ammonium sulfate formed in the plasma reaction vessel 7. After that, the cleaned exhaust gas is discharged from an exhaust pipe 14 to the atmosphere through a chimney 15.
