DECOMPOSING METHOD OF ORGANOHALOGEN COMPOUNDS BY HIGH FREQUENCY INDUCTION PLASMA AND ITS EQUIPMENT

摘要

PURPOSE:To provide a method to decompose organohalogen compounds efficiently and equipment for decomposition of organic halogen compounds and its method which is less apt to generate dioxins even in mass and efficient decomposing of organohalogen compounds. CONSTITUTION:Since the pressures in the plasma torch 1 and the chamber (reaction furnace) 4 are kept under a reduced pressure lower than atmospheric pressure, plasma is stably maintained, and since the mixed gas of water vapor and organohalogen compounds is directly introduced into the plasma torch 1, the organohalogen compounds can efficiently be decomposed. In addition, the generation of dioxins can be suppressed by quenching exhaust gas of organohalogen compounds decomposed by plasma with an aqueous alkaline solution.
