Thermal decomposer for waste

摘要

An inventive thermal decomposition apparatus for wastes comprises: a heating chamber for heating the wastes; an inlet port for introducing the wastes into heating chamber; at least one pair of electrodes provided within the heating chamber; a plurality of balls each taking the form of a sphere whose main ingredient is carbon, provided between the at least one pair of electrodes so as to produce an electric discharge when a voltage is applied across the at least one pair of electrodes; an outlet port for discharging out of the heating chamber gases into which the wastes are thermally decomposed; oxygenless or vacuum state forming means or evacuating means for placing the heating chamber in an oxygenless or vacuum state such that the balls are placed in an oxygenless state. According to the present invention, an inexpensive thermal decomposition apparatus for wastes is provided which thermally decomposes almost all wastes at a high temperature of not lower than about 3000 DEG C without producing any harmful substances such as soot dust, chlorine compounds such as hydrogen chloride, nitrogen compounds such as NOx and/or dioxin.
