Patent

CA 2298502

The invention especially relates to components used as ceramic catalysts in denitration plants. In said plants, the catalysts are impinged upon by low frequency sound. This enables the surfaces of the catalysts to be cleaned and simultaneously enhances their efficacy. If the catalysts cannot be reactivated they are subjected to final intensive cleaning wherein they are exposed once more to low frequency sound. Subsequently, the catalysts are crushed and the ceramic material can be used in all cases where the chemical properties of the material is of no particular significance. The cleaned particles containing pollutants are dumped or disposed of in melting chamber furnaces.

L'invention concerne notamment des catalyseurs céramiques utilisés dans des installations de dénitruration. Dans ces dernières, on applique aux catalyseurs des sons basse fréquence permettant un nettoyage des surfaces des catalyseurs et simultanément un accroîssement de leur efficacité. Si ces derniers ne sont plus réactivables, ils sont soumis à un nettoyage final intensif, et ce, à nouveau par exposition à l'action des sons basse fréquence. Les catalyseurs sont ensuite broyés et le matériau céramique peut être utilisé dans tous les cas où les caractéristiques chimiques du matériau ne revêtent pas une importance notable. Les particules polluantes éliminées par nettoyage sont évacuées à la décharge ou bien éliminées dans des foyers à cendres fondues.
