Abstract
Depurador de pasta de papel. Es un depurador cerrado a presión y tiene tres fases de depuración independientes. Incluye un rotor dividido en dos partes diferentes (3, 5), girando en el interior de una carcasa envolvente (2) de doble pared (6, 7). La pasta de papel entra por un conducto tangencial (8), saliendo los contaminantes pesados por otro conducto lateral (9), mientras que el flujo ligero pasa por un rebosadero (11) hacia la zona del rotor (1). Parte de este flujo pasa a través de orificios al interior de la carcasa (2), saliendo a1 exterior por un conducto (12) del flujo aceptado, en tanto que el resto atraviesa el resto del rotor configurado a modo de cesta (5) pasando por un conducto axial (13) para juntarse con el anterior. El flujo rechazado que no atraviesa estas paredes del rotor (1), sale al exterior por un conducto (15). El flujo aceptado se forma pues con sentidos inversos de circulación en el rotor, existiendo paletas fijas o móviles para uniformizar el flujo.Paper pulp scrubber. It is a closed pressure scrubber and has three independent debug phases. It includes a rotor divided into two different parts (3, 5), rotating inside a double-walled casing (2) (6, 7). The pulp enters through a tangential duct (8), heavy contaminants leaving another side duct (9), while the light flow passes through an overflow (11) towards the rotor area (1). Part of this flow passes through holes inside the housing (2), exiting outside through a conduit (12) of the accepted flow, while the rest passes through the rest of the rotor configured as a basket (5) passing by an axial conduit (13) to join the previous one. The rejected flow that does not pass through these rotor walls (1), goes outside through a duct (15). The accepted flow is thus formed with reverse directions of circulation in the rotor, there are fixed or mobile vanes to standardize the flow.
