Abstract

LA INVENCION SE REFIERE A UN METODO Y A UNA INSTALACION PARA TRATAR GASES DE SALIDA DESDE UN HORNO DE FUNDICION EN SUSPENSION (1). EN EL METODO, LOS GASES DE SALIDA SON CONDUCIDOS DESDE LA CHIMENEA DE CAPTACION (2) DE UN HORNO DE FUNDICION EN SUSPENSION 81) A UNA CALDERA DE RECUPERACION DE CALOR (5), EL POLVO DE CHIMENEA CONTENIDO EN EL GAS DE SALIDA ES DESACTIVADO EN LA CALDERA DE RECUPERACION DE CALOR (5) MEDIANTE UN GAS DE DESACTIVACION , LOS GASES DE SALIDA SON ENFRIADOS Y LA ENERGIA TERMICA CONTENIDA EN LOS GASES DE SALIDA, RECUPERADA, Y LOS GASES DE SALIDA ENFRIADOS SON CONDUCIDOS DESDE LA CALDERA DE RECUPERACION DE CALOR  (5) A UN FLTRO ELECTRICO (15). EN EL FILTRO ELECTRICO (15), EL POLVO DE CHIMENEA ES SEPARADO DEL GAS DE SALIDA. EL METODO EMPLEA UNA CALDERA DE RECUPERACION DE CALOR (5) QUE COMPRENDE UNA CAMARA DE RADIACION (6) Y UNA UNIDAD DE ENFRIAMIENTO POR EVAPORACION (11). EL METODO COMPRENDE ETAPAS EN DONDE EL GAS DE SALIDA ES RECIBIDO DESDE LA CHIMENEA DE CAPTACION (2) DEL HORNO DE FUNDICION EN SUSPENSION (1) POR LA CAMARA DE RADIACION (6) DE LA CALDERA DE RECUPERACION DE CALOR, EL POLVO DE CHIMENEA CONTENIDO EN EL GAS DE SALIDA ES DESACTIVA POR  UN GAS DE DESACTIVACION EN LA CAMARA DE RADIACION (6) DE LA CALDERA DE RECUPERACION DE CALOR, LOS GASES  DE SALIDA SON PREENFRIADOS EN LA CAMARA DE RADIACION (6) DE LA CALDERA DE RECUPERACION DE CALOR, LOS GASES DE SALIDA PREENFRIADOS SON CONDUCIDOS DESDE LA CAMARA DE RADIACION (6) DE LA CALDERA DE RECUPERACION DE CALOR A LA UNIDAD DE ENFRIAMIENTO POR EVAPORACION (11) DE LA CALDERA DE RECUPERACION DE CALOR, LOS GASES DE SALIDA SON ENFRIADOS MEDIANTE ROCIO CON AGUA EN LA UNIDAD DE ENFRIAMIENTO POR EVAPORACION (11) DE LA CALDERA DE RECUPERACION DE CALOR, Y DESDE LA UNIDAD DE ENFRIAMIENTO POR EVAPORACION (11) DE LA CALDERA DE RECUPERACION DE CALOR, EL VAPOR ACUOSO FORMADO DEL GAS DE SALIDA Y DEL ROCIO DE AGUA ES CONDUCIDO AL FILTRO ELECTRICO. (15).THE INVENTION REFERS TO A METHOD AND AN INSTALLATION FOR TREATING OUTLET GASES FROM A SUSPENSION CASTING OVEN (1). IN THE METHOD, THE OUTLET GASES ARE LEADED FROM THE COLLECTION CHIMNEY (2) OF A SUSPENSION CASTING OVEN 81) TO A HEAT RECOVERY BOILER (5), THE CHIMNEY DUST CONTAINED IN THE OUTLET GAS IS DEACTIVATED IN THE HEAT RECOVERY BOILER (5) BY DEACTIVATING GAS, THE OUTPUT GASES ARE COOLED AND THE THERMAL ENERGY CONTAINED IN THE OUTLET GASES, RECOVERED, AND THE COOLED OUTPUT GASES ARE LEADED FROM THE HEAT RECOVERY BOILER (5) TO AN ELECTRIC FLTRO (15). IN THE ELECTRIC FILTER (15), THE CHIMNEY DUST IS SEPARATED FROM THE EXHAUST GAS. THE METHOD USES A HEAT RECOVERY BOILER (5) INCLUDING A RADIATION CHAMBER (6) AND AN EVAPORATION COOLING UNIT (11). THE METHOD INCLUDES STAGES WHERE THE OUTPUT GAS IS RECEIVED FROM THE COLLECTION CHIMNEY (2) OF THE SUSPENSION CASTING OVEN (1) BY THE RADIATION CHAMBER (6) OF THE HEAT RECOVERY BOILER, THE CHIMNEY DUST CONTAINED IN THE OUTLET GAS IT IS DEACTIVATED BY A DEACTIVATION GAS IN THE RADIATION CHAMBER (6) OF THE HEAT RECOVERY BOILER, THE OUTLET GASES ARE PRE-COOLED IN THE RADIATION CHAMBER (6) OF THE HEAT RECOVERY BOILER, THE PRE-COOLED OUTPUT GASES ARE CONDUCTED FROM THE RADIATION CHAMBER (6) OF THE HEAT RECOVERY BOILER TO THE EVAPORATION COOLING UNIT (11) OF THE HEAT RECOVERY BOILER, THE OUTLET GASES ARE COOLED BY SPRAYING WITH WATER IN THE EVAPORATION COOLING UNIT (11) OF THE HEAT RECOVERY BOILER, AND FROM THE EVAPORATION COOLING UNIT (11) OF THE HEAT RECOVERY BOILER, THE AQUEOUS VAPOR FORMED FROM THE EXHAUST GAS AND THE WATER SPRAY IS LEADED TO THE ELECTRIC FILTER. (fifteen).
