Abstract

Recipiente (10) de filtro de lecho profundo para filtrar contaminantes de una corriente de líquido contaminado, que comprende: dicho recipiente (10) que define un espacio interno para contener un líquido que va a filtrarse; un lecho (12) de medio de filtro granular dispuesto dentro del recipiente en al menos una región inferior del mismo; un distribuidor (20) de entrada situado en una región superior del recipiente (10), para recibir un líquido contaminado y distribuir ese líquido hacia abajo y de manera sustancialmente uniforme a través de la sección transversal del recipiente durante un ciclo de filtrado; medios de filtro de salida, acoplados a un cabezal (30) colector de salida, para retirar líquido filtrado del recipiente (10) al tiempo que retiene el medio (12) de filtro granular dentro del recipiente durante dicho ciclo de filtrado; estando situados dichos medios de filtro de salida en dicha región inferior de dicho recipiente (10) y abajo en dicho medio (12) de filtro; medios (22, 23) de retirada por lavado a contracorriente, situados en dicha región superior de dicho recipiente e independientes tanto de dicho distribuidor (20) de entrada como de dichos medios de filtro de salida, para retirar una mezcla de gas y líquido del recipiente durante un ciclo de limpieza al tiempo que se retiene el medio (12) de filtro granular dentro del recipiente durante dicho ciclo de limpieza; caracterizado porque tiene además: al menos una boquilla (40) radial o una pluralidad de boquillas (40) radiales separadas uniformemente cerca de la base del lecho de medios de filtro para dispensar, durante dicho ciclo de limpieza, y radialmente hacia fuera de la misma, una corriente a chorro de burbujas de gas dispersadas dentro de un líquido de lavado a contracorriente a una velocidad de salida por boquilla para producir una dispersión de gas uniforme dentro del líquido de lavado a contracorriente, estando situadas la boquilla o pluralidad de boquillas abajo en el recipiente y dentro de dicho medio (12) de filtro granulado y ubicadas lo suficientemente cerca de un fondo del lecho (12) de modo que al menos una parte de dicha corriente a chorro va dirigida hacia dichos medios de filtro de salida; y al menos un conducto (36) dispuesto dentro del recipiente (10) para transportar la mezcla controlada de gas y líquido a dicha al menos una boquilla (40) radial.
