Abstract

Esta invencion se refiere a un dispositivo para la filtracion de pastas acuosas y a un sistema, de tipo cal-yeso, desulfurador de gas humedo de humero, el cual comprende un dispositivo de filtracion de pastas acuosas como un recurso para la separacion (concentracion) del yeso. Este dispositivo de filtracion de pastas acuosas comprende un tanque, con un tubo de suministro de la pasta acuosa en su parte superior y un agujero de descarga del filtrado en su fondo, una capa de arena del filtro se coloca sobre su fondo, un acumulador de pasta acuosa se dispone sobre la capa de arena del filtro, y un vibrador se coloca dentro del acumulador de la pasta acuosa, para vibrar esta pasta acuosa. La presente invencion no solo mejora notablemente la capacidad de separacion de los solidos y líquidos, sino también produce ahorros en el costo y el espacio.
