METHOD AND INSTALLATION FOR PROCESSING OF HAZARDOUS WASTE FROM RECYCLING LEAD-ACID BATTERIES

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.
