Abstract
Un aparato distribuidor de flujo para aceptar una corriente de líquido desde una entrada e introducir dicha corriente de líquido, a través de una pluralidad de lumbreras , en un depósito de tratamiento que contiene una cierta cantidad de sólidos en partículas para producir un flujo ascendente de dicho líquido en dicho depósito de tal manera que los sólidos en partículas se fluidifican sin introducir turbulencia excesiva, que comprende: portales de fluido, cada uno de los cuales comunica con al menos una de dichas lumbreras y que constituye una trayectoria de flujo de paredes divergentes de área en sección transversal creciente con el aumento de la distancia a una lumbrera de comunicación, con lo que la velocidad del líquido que atraviesa dichos portales de fluido desde dicha lumbrera disminuye uniformemente, estando dichos portales de fluido orientados de manera que dichas trayectorias de flujo dirigen el flujo líquido de las mismas según un ángulo comprendido en el intervalo que va desde la horizontal hasta verticalmente hacia abajo en dicho depósito, difusores de flujo que tienen paredes de configuración o limitación de flujo, cada uno de los cuales está en comunicación de flujo, cada uno de los cuales está enc comunicación de fluido con un portal de fluido en un extremo del mismo y orientado para dirigir flujo desde dicho portal de fluido en una dirección en general verticalmente hacia arriba en dicho depósito para fluidificar dichos sólidos. En partículas.
