Abstract

PROCEDIMIENTO E INSTALACION PARA EL SECADO Y LA MOLIENDA FINA DE CARBON, QUE PRETENDE INDEPENDIZAR AUTOMATICAMENTE LA MOLIENDA DEL CARBON CON LOS REQUERIMIENTOS DEL MISMO, ASI COMO UNA RAPIDA PUESTA EN MARCHA A PLENA CARGA DE LA INSTALACION. EN EL MOLINO (1) SE SECA, ADEMAS DE MOLERSE, EL CARBON CON EL GAS CALIENTE DE LOS REALIMENTADORES (37 Y 39). EL AIRE DEL REALIMENTADOR (39) PROVIENE DEL REFRIGERADOR (21) Y DEL AIRE TERCIARIO (17) QUE SALE DEL QUEMADOR (22), ENCARGADO DE PRECALENTAR EL CALCINADOR. EL QUEMADOR (22) OBTIENE EL AIRE DEL VENTILADOR (11) QUE PROVIENE DEL SEPARADOR DE CARBON FINO (6), PORTANDO POLVO DE CARBON EN SUSPENSION. EL CARBON DEL SEPARADOR SE ALMACENA EN EL SILO (8), PARA MEZCLARSE LUEGO CONTROLADAMENTE EN EL MEZCLADOR (29) CON PARTE DEL AIRE PROVENIENTE DEL VENTILADOR (11), E INSUFLARSE EN EL HORNO (19) A TRAVES DEL QUEMADOR (31). PARA LA PUESTA EN MARCHA DEL QUEMADOR (22), SE INYECTA COMBUSTIBLE DEL DEPOSITO (23), Y AL ALCANZAR LA TEMPERATURA DE REGIMEN 800GC PUEDESER APAGADO O NO, SEGUN LAS NECESIDADES DE AIRE TERCIARIO EN EL CONDUCTO (17) QUE VA AL CALCINADOR. DE APLICACION EN FABRICAS DE CEMENTO, ENTRE OTRAS.
