INSTALLATION AND METHOD FOR RECOVERING CARBON OR GLASS FIBRES FROM COMPOSITE MATERIALS

摘要

Plant (1) for recovering carbon or glass fibres from composite materials comprising said fibres in a polymer matrix comprises a tunnel kiln (2) along which said materials are conveyed inside containers (6), in which said tunnel kiln comprises a pyrolysis zone (3), in which said composite materials are subjected to a pyrolysis process in an atmosphere devoid of oxygen, a gasification zone (3) in which said materials are subjected to a gasification process in the presence of oxygen, and an intermediate separating zone (5), placed between the pyrolysis zone (3) and the gasification zone (4), in which a plurality of second injecting devices (23) to deliver nitrogen to said intermediate zone (5) is provided, so as to prevent the atmosphere of the pyrolysis zone (2) coming into contact with the atmosphere of the gasification zone (3).
