Abstract

QUE CONSISTE EN COLOCAR UN MATERIAL A FILTRAR EN CONTACTO CON UNA SUPERFICIE FILTRANTE DE UN MEDIO FILTRANTE DISPUESTO EN UNA SECADORA A SUCCION Y SOBRE DICHA SUPERFICIE DEL MEDIO FILTRANTE SE FORMA UNA TORTA DE FILTRO QUE LUEGO ES SOMETIDA A UN PROCESO DE SECADO ANTES DE SEPARARLA DE LA SUPERFICIE FILTRANTE. EL PROCESO DE SECADO DE LA TORTA DE FILTRO SE LLEVA A CABO EN UNA ETAPA DE SECADO DURANTE LA CUAL SE PREVIENE EL FLUJO DE GAS A TRAVES DEL MEDIO FILTRANTE; Y, OTRA ETAPA DURANTE LA CUAL EL GAS FLUYE A TRAVES DEL MEDIO FILTRANTE. ADEMAS ENTRE LA ETAPA DE SECADO DONDE SE PREVIENE QUE FLUYA EL GAS Y LA ETAPA DE SECADO DURANTE LA CUAL EL GAS FLUYE, SE EFECTUA LA ETAPA DE LAVADO DE LA TORTA DE FILTRO
