Abstract
Répartiteur de débit pour réacteur biologique à lit fluidisé. Il comprend un dispositif permettant de réduire la vitesse des courants de liquide arrivant d'une façon uniforme et sans turbulence. Des orifices d'entrée communiquent avec des conduits d'entrée comportant des parois divergentes qui ralentissent le liquide admis. Les conduits d'entrée introduisent les courants de liquide sur plusieurs trajets de diffusion entre des chicanes montées sur le fond du réacteur. Les chicanes peuvent avoir des formes de section trapézoïdale dont la plus grande dimension horizontale est située à leur partie inférieure. Les trajets sont donc délimités par des parois divergentes et ralentissent encore le liquide qui s'y écoule. Application au traitement des matières résiduaires municipales et industrielles par exemple.
