Abstract
Disposición de grados múltiples para el lavado en contra corriente de materias sólidas suspendidas, preferentemente de cristales, con ayuda de hidrociclones (9a 9f ) conectados sucesivamente así como bombas correspondientes (11 11e) y sumideros de bomba (4 4e) y conductos que comunican los antes ya mencionados elementos de construcción estando previstos conductos de aflujo para el líquido lavador (15) y las materias sólidas (1) suspendidas asi como desag¿ ues para el líquido lavador impurificado (17, 17a, 17b) y para la suspensión (14) lavada y condensada en que además el líquido lavador se transporta en contra corriente (F2) respecto a la dirección de transporte (F1) de las materias sólidas suspendidas y en que las materias sólidas suspendidas se tratan a presión y temperatura elevadas, caracterizada porque los hidrociclones (9a 9f ), conectados sucesivamente o los grupos conectados sucesivamente de varios hidrociclones (9a 9f) conectados en paralelo, (ambos mencionados en los que sigue solamente como \grupo de hidrociclón") con corrientes inferiores (13a 13f) y rebosamientos superiores (8a 8f ) y los sumideros de bomba (4 4f) con las bombas (11 11e) o partes de bombas que penetran en los mismos, están alojados en un recipiente (18) común, resistente a la presión y termo aislado y porque este recipiente está provisto del conducto de aflujo (1) para materias sólidas suspendidas, un conducto de afl jo (15) y un conducto de salida (17) para el líquido lavador y un conducto de salida (14) para la suspensión lavada y condensada.
