Abstract

EN UNA PLANTA DE HORNO DE SECADO PARA QUEMAR ESCORIA DE MATERIAS PRIMAS MINERALES, TALES COMO MATERIAS PRIMAS DE CEMENTO, Y COMPRENDIENDO UN HORNO DE SECADO (1), UN PRECALCINADOR (4), UN PRECALENTADOR (6, 7, 8) Y UN FILTRO DE CONDUCTO DE GAS (31), SE DESVIAN PARTE DE GASES DEL CONDUCTO DEL HORNO DESDE EL PRECALCINADOR Y DEL PRECALENTADOR A TRAVES DE UN BYPAS (20, 30), ESTANDO SUJETA LA CANTIDAD DE GASES DEL CONDUCTO DERIVADOS A UN ENFRIADO POR INMERSION EN UNA CAMARA (21), HUMEDECIDO CON AGUA Y ENFRIADO EN UN REACTOR (23), CAUSANDO ASI A LOS CLORUROS Y ALCALIS EN EL GAS DESVIADO A DEPOSITARSE EN PARTICULAS DE POLVO QUE SON PRECIPITADAS JUNTO CON EL POLVO DEL MATERIAL EN LOS GASES, DESDE EL ULTIMO EN UN SEPARADOR (25). EL GAS DEL CONDUCTO DESVIADO SIENDO ASI CASI PURIFICADO DE COMPUESTOS DAÑINOS ES ENTONCES ALIMENTADO AL FILTRO (31) O RECIRCULADO AL DESVIO DE TAL MANERA QUE AL MENOS PARTE DE LOS COMPUESTOS PRECIPITADOS Y POLVO DE MATERIAL DEL REACTOR (23) Y DEL SEPARADOR ES VUELTO AL REACTORPARA UN TRATAMIENTO DE RENOVACION EN EL MISMO.
