Abstract

LA PRESENTE INVENCION SE REFIERE EN PRIMER LUGAR A UN PROCESO DE TRATAMIENTO DE CARBON EN POLVO EN UNA INSTALACION DE INYECCION DE COMBUSTIBLES SOLIDOS. TAL INSTALACION COMPRENDE UN SILO DE ALMACENAMIENTO (12) DE CARBON EN POLVO, AL MENOS UNA CAMARA (2, 4) CONECTADA AL CIRCUITO DE TRANSPORTE NEUMATICO (6) DEL CARBON, AL MENOS UNA CRIBA FILTRANTE (14, 16) CONECTADA ENTRE CADA CAMARA (2, 4) Y EL SILO (12), UNA FUENTE DE GAS INERTE A PRESION PARA LA PRESURIZACION DE CADA CAMARA (2, 4) Y LA FORMACION DE LA CORRIENTE DE PROPULSION NEUMATICA DEL CARBON Y UN CIRCUITO DE IGUALACION DE PRESION Y DE DEPRESURIZACION DE CADA CAMARA (2, 4) A TRAVES DE UN FILTRO (22). SEGUN LA PRESENTE INVENCION, LA MAYOR PARTE DEL GAS INERTE DE DEPRESURIZACION DE CADA CAMARA (2, 4) ESTA SOMETIDA A UNA OPERACION DE FILTRACION (26, 28) ANTES DE SER INYECTADA EN EL FONDO DEL SILO DE ALMACENAMIENTO EN LA MASA DE CARBON Y DE SER LIBERADA A TRAVES DE UN FILTRO (22) EN LA PARTE SUPERIOR DEL SILO. LA PARTE RESIDUAL DEL GAS INERTE DE DEPRESURIZACION SE DESVIA DIRECTAMENTE HACIA LA PARTE SUPERIOR EN EL SILO DE ALMACENAMIENTO (12). LA PRESENTE INVENCION DESCRIBE TAMBIEN UN DISPOSITIVO PARA LA APLICACION DEL PROCESO.
