Abstract

SE TRATA DE UNA INSTALACION PARA LA RECUPERACION DE DISOLVENTES, ESPECIALMENTE PARA INSTALACIONES DE FABRICACION DE MATERIAL DE CINTAS, PREFERENTEMENTE CINTAS DE VIDEO Y DE CASSETTE. ESTA INSTALACION ESTA PROVISTA DE UN REGULADOR DE CALOR. ESTA INSTALACION ESTA DOTADA DE UN GAS PREVIAMENTE PURIFICADO POR UN DISOLVENTE PROCEDENTE DE UN PRECIPITADOR DE DISOLVENTE. LA CORRIENTE DE GAS Y EL DISOLVENTE SALEN POR UN CONDUCTO DEL SECADOR Y SON CALENTADAS. LA MAYOR PARTE DEL GAS, QUE SE HA CALENTADO, ES DEVUELTA AL SECADOR. UNA PEQUEÑA PORCION DE GAS ES SOMETIDA A UNA BAJA TEMPERATURA Y SEPARADA DE LOS RESTOS DE DISOLVENTES. POCO DESPUES DICHA PEQUEÑA PORCION ES EVAPORADA Y PASA A FORMAR PARTE DEL GAS INERTE PARA SER LLEVADO AL FILTRO DEL SECADOR. ALLI SE PRODUCE UNA CORRIENTE DE GAS EN EL SECADOR Y DIRIGIDA HACIA FUERA. EL PROCEDIMIENTO PROPUESTO ES ESPECIALMENTE REALIZABLE EN LA INSTALACION DESCRITA
