Abstract

SE PRESENTA UNA SEPARACION TERMICA DE SOLIDOS DEPURABLES EN SOLUCIONES O SUSPENSIONES Y LA OBTENCION DE UN DESTILADO EN GRAN PARTE LIBRE DE MATERIAL SOLIDO QUE PERMITE OBTENER UN PRODUCTO UTILIZABLE CASI EN SU TOTALIDAD Y RECUPERADO LIMPIO, ASI COMO DISMINUCION DE LOS PRODUCTOS DE DESECHO. PARA ELLO SE REALIZA UNA CONCENTRACION EN UN PRIMER TUBO DE CORRIENTE O CONDUCCION (6) CALENTABLE HASTA EL LIMITE SUPERIOR, QUE A TRAVES DE UNA LENTA CARGA DE LAS PAREDES INTERIORES CON MATERIALES SOLIDOS RESPECTIVAMENTE A TRAVES DE UN ESTRANGULAMIENTO DE LA SECCION TRANSVERSAL DE LA CORRIENTE SE CONSIGUE UNA CONCENTRACION EN UNA SEGUNDA ETAPA CON UN TUBO ROTATIVO CONSTRUIDO COMO TUBO DE CORRIENTE COMO APARATO DE PALETAS DE TORNILLO SINFIN (9), CUYA PARED INTERIOR ESTA PREPARADA, Y DE AQUI SE CONTINUA AL EXTREMO DE ESTE TUBO DE CORRIENTE (9) DONDE SE SEPARAN UNOS DE OTROS LOS VAPORES Y LOS PRODUCTOS SOLIDOS.
