Abstract

Reactor (1) de chorro libre con empuje ascensional para la ejecución de procesos de transformación de materiales, químicos o físicos, en un medio líquido, que comprende un recipiente libre de partes móviles, con una parte (3) inferior que se estrecha hacia abajo y una parte (2) superior, un dispositivo para inyección (6) de gas dispuesto en la parte inferior del recipiente y que hace posible una circulación por chorro libre con empuje ascensional, un dispositivo para la alimentación de un medio (8) líquido, cuya abertura (9) de salida se encuentra en la zona de la corriente nuclear del velo de burbujas que se forma en condiciones de operación, y un dispositivo (5) para la retirada de una suspensión en la parte que se estrecha del reactor, caracterizado porque presenta una parte superior con forma cilíndrica y solamente un único tubo (10) de introducción dispuesto axialmente en ella, cuyo canto superior, en condiciones de operación, se sitúa por encima del nivel del líquido y cuyo canto inferior se sitúa por fuera de la corriente nuclear del velo de burbujas que se forma en condiciones de operación y porque está dispuesto un dispositivo (11) para la extracción de un medio líquido del recinto formado entre la pared y el tubo de introducción.
