Abstract
The invention relates to a process and device for treating pollutant fusible materials which are conductors of electricity in the molten state. The process consists in introducing the waste into an induction furnace (11, 40) comprising an inductor circuit (1, 39), and a crucible (1, 8; 38), directly heating the said materials in the crucible by induction so that they melt, induction being created by the inductor circuit (1, 39) galvanically connected to a power source (6), the crucible (1, 8; 38) being the seat of no eddy current, removing the molten products from the furnace, the said products being gathered, after cooling, in non-leachable form.
Claims32
Process for treating pollutant materials which are fusible and conductors of electricity in the melted state, which process comprises:
- (a) introducing the said materials into an induction furnace comprising an inductor circuit,
- (b) directly heating the said materials by induction in said furnace to ensure their melting, the induction being created by the inductor circuit which is galvanically connected to a power source,
- (c) removing the melted products from the said furnace, and
- (d) cooling the removed products, such that the cooled products are in non-leachable form.
Device for treating toxic materials which are fusible and conductors in the molten state, comprising:
- (a) means for introducing the materials,
- (b) an induction furnace comprising an inductor circuit that is galvanically connected to a power source, said furnace directly heating said materials by induction to ensure their melting,
- (c) means for removing the molten products, and
- (d) means for cooling the removed products, such that said cooled products are in non-leachable form.
