Title
(EN) METHOD AND INSTALLATION FOR PROCESSING OF HAZARDOUS WASTE FROM RECYCLING LEAD-ACID BATTERIES
(FR) PROCÉDÉ ET INSTALLATION DE TRAITEMENT DE DÉCHETS DANGEREUX ISSUS DU RECYCLAGE DE BATTERIES PLOMB-ACIDE
Abstract
(EN) The Invention will find application in the processing of hazardous waste, which contains lead compounds, polymers, metals and other waste. The method includes stages as follow: A first stage (A) where is conducted a pre-processing of hazardous waste by reducing the size of the waste, a neutralization with an alkaline solution, a chemical treatment for cleaning out of the pollutants, and drying. A second stage (B), where is conducted a sorting of the processed AGS and PC waste for landfilling, and polypropylene is released, as well as polyethylene separators with a silicon dioxide filler which are fed in third stage (C) for processing via gasification. This results in a gas phase and gives out amorphous silicon dioxide which is directed for its subsequent use. The gas phase is fed to a fourth stage (D), which is a combustion process at a temperature not lower than 900°C in a thermal oxidizer. After the combustion process, the hot gases are sent in energy module (E) for utilization.
(FR) La présente invention s'applique au traitement de déchets dangereux, qui contient des composés de plomb, des polymères, des métaux et d'autres déchets. Le procédé comprend les étapes suivantes : une première étape (A) où est mis en œuvre un prétraitement de déchets dangereux par réduction de la taille des déchets, une neutralisation avec une solution alcaline, un traitement chimique pour le nettoyage des polluants, et le séchage. Une deuxième étape (B), dans laquelle est effectué un tri des déchets AGS et PC traités pour la mise en décharge, et du polypropylène est libéré, ainsi que des séparateurs de polyéthylène avec une charge de dioxyde de silicium qui sont introduits dans une troisième étape (C) pour un traitement par gazéification. Il en résulte une phase gazeuse et on obtient du dioxyde de silicium amorphe qui est dirigé vers son utilisation ultérieure. La phase gazeuse est introduite dans une quatrième étape (D), qui est un procédé de combustion à une température qui n'est pas inférieure à 900 °C dans un dispositif d’oxydation thermique. Après le processus de combustion, les gaz chauds sont envoyés dans le module d'énergie (E) en vue d'une utilisation.
