Abstract

L'invention concerne un procédé et un dispositif d'évacuation et de dégazage d'une bouillie d'une cuve d'attaque. Le dispositif comporte en haut de cuve (2), un trop-plein (3) formant déversoir et un réservoir (4) débouchant sur une pompe (9) et il est caractérisé en ce qu'il comporte d'une part un réceptacle (5) placé entre le déversoir et le réservoir, qui comprend une surface de raccordement (11) et d'autre part une tuyauterie (6) partant du pied de cuve de débouchant dans le réceptacle. Le dispositif peut etre avantageusement utilisé dans la fabrication de l'acide phosphorique.
