Abstract

UN PROCEDIMIENTO DE ELIMINACION DE INCRUSTACIONES DEL ACERO INOXIDABLE, UTILIZANDO UNA SOLUCION ACUOSA, QUE CONTIENE PEROXIDO DE HIDROGENO Y UN ACIDO INORGANICO, P.EJ. ACIDO HIDROCLORICO O SULFURICO. UNA BANDA DE ACERO INOXIDABLE LAMINADO EN CALIENTE O RECOCIDO (10) CUBIERTA DE INCRUSTACIONES, SE SUMERGE EN ACIDO INORGANICO CALIENTE, CONTENIDO EN TANQUES DE DECAPADO (12) Y (14). A CONTINUACION, LA BANDA PUEDE PRESENTAR AUN CANTIDADES RESIDUALES DE INCRUSTACION FUERTEMENTE ADHERIDA (11). DICHA INCRUSTACION, SE ACTIVA MEDIANTE UNA SOLUCION, QUE CONTIENE EL ACIDO INORGANICO Y PEROXIDO DE HIDROGENO, APLICADA A DICHA BANDA MEDIANTE, POR EJEMPLO, UNA TOBERA DE PULVERIZACION (16), QUE SE EXTIENDE TRANSVERSALMENTE, A LO LARGO DE LA TOTALIDAD DE LA BANDA Y SITUADA POR ENCIMA DE LA MISMA, Y OTRA TOBERA DE PULVERIZACION (18), QUE SE EXTIENDE TRANSVERSALMENTE, A LO LARGO DE LA TOTALIDAD DE LA BANDA Y SITUADA POR DEBAJO DE LA MISMA. PUEDE SER DESEABLE, PASAR LA BANDA ACTIVADA NUEVAMENTE, A TRAVES DEL ACIDO INORGANICO CALIENTE Y REACTIVAR DICHA BANDA A VELOCIDADES DE PRODUCCION MUY ELEVADAS, PARA ASEGURAR LA COMPLETA ELIMINACION DE LA INCRUSTACION. EL PEROXIDO DE HIDROGENO QUE GOTEA DESDE LA BANDA, SE RECOGE EN UN DEPOSITO DE RECOGIDA (30) Y SE HACE FLUIR HACIA EL INTERIOR DE UN TANQUE (28). PREFERIBLEMENTE, LA SOLUCION ACUOSA CONSUMIDA Y RECOGIDA, QUE CONTIENE EL ACIDO INORGANICO Y EL PEROXIDO DE HIDROGENO GASTADO, SE DISTRIBUYE EN LOS TANQUES DE DECAPADO. DICHA SOLUCION ACUOSA, CONTRIBUYE A LA ELIMINACION DE CUALQUIER INCRUSTACION RESIDUAL O MANCHA RESIDUAL SOBRE LA BANDA, MEJORANDO POR TANTO LA LIMPIEZA DE LA BANDA DECAPADA.
