Plasma reaction apparatus, and plasma reaction method of persistent gas

摘要

The present invention relates to a plasma reaction apparatus and a plasma reaction method of a persistent gas. More particularly, the present invention relates to a plasma reaction apparatus which is applied to the reforming of fuel by generating rotating arc plasma and using the rotating arc being generated, the chemical treatment of a persistent gas, and a plasma reaction method using the same. For this purpose, a raw material for a reaction is allowed to flow through an inflow hole in a swirl structure so that the raw material forms a rotating flow to progress. Accordingly, the raw material is sufficiently reacted in a plasma reaction space of a restrictive volume, and a high temperature plasma reaction is more promptly performed. Furthermore, a plasma reaction zone is expanded, prior to discharge, by a broad area chamber formed as the width of an upper part of a furnace is expanded, and plasma being generated is expanded and stayed as a pointed end spaced from an electrode at a predetermined interval is formed at an expanded end. Accordingly, the present invention relates to a plasma reaction apparatus and a plasma reaction method of a persistent gas, and an apparatus decreasing NOx by an occlusion catalyst, all of which are capable of excluding the discontinuity of the plasma reaction zone.
