Patent

CA 2575390

The invention relates to a method for treating wastes, in particular from the production of mineral fibres such as fibreglass wool or rock fibres associated with organic binders and optionally with water or other metal and/or organic matters consisting in fusing a waste mass (9) by supplying a pure oxygen or an oxygen-enriched air in order to obtain a mineral material usable in the form of a vitreous raw material for glass melting and in inputting energy by means of at least one burner submerged under the waste mass (9). A device for carrying out said method is also disclosed.

L'invention a pour objet un procédé de traitement de déchets, notamment issus delà production de fibres minérales, tels que des fibres de laine de verre ou de roche associées à des liants organiques et éventuellement de l'eau ou d'autres matières métalliques et/ou organiques, comprenant une étape de fusion d'une masse de déchets (9) utilisant un apport d'oxgène pur ou d'air enrichi en oxygène, en vue de former une matière minérale apte à être utilisée comme matière première vitrifiable dans un procédé de fusion du verre, caractérisé en outre par un apport d'énergie par le biais d'au moins un brûleur immergé (11) sous la nmasse de déchets (9) . L' inventation a également pour objet un dispositif de mise en oeuvre d'un tel procédé.
