ORGANIC HALOGEN COMPOUND DISCHARGE DECOMPOSITION DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an organic halogen compound discharge decomposition device preventing corrosion damage of a downstream end of a discharge tube.

SOLUTION: The organic halogen compound discharge decomposition device is provided with a discharge tube 4 in which a gas containing the organic halogen compound flows and thermal plasma by a micro wave is formed at the inside; and a cavity 25 arranged so as to surround the discharge pipe 4 and determining electric field distribution of the discharge tube. The downstream end of the discharge tube 4 is at the downstream side of a lower end plate 25a of the cavity and an average flow speed of the gas flowing in the discharge tube 4 is made to v (m/s), it is set to a position of 0 to 4.7×10-3×v (m) or less.
