Abstract

L'invention concerne un dispositif pour éliminer la mousse dans des liquides ayant une forte tendance à mousser. On utilise une auge inclinée par rapport à l'horizontale, comportant des chicanes transversales relativement à la direction du flux de liquide laissant des orifices pour l'écoulement au fond de plus en plus petits entre le corps de l'auge et les chicanes dans le sens du flux. Application à la préparation de brai dépourvu d'eau et de mousse selon un procédé fonctionnant en continu avec des débits exploitables.The invention relates to a device for removing foam in liquids having a strong tendency to foam. A trough inclined relative to the horizontal is used, comprising transverse baffles relative to the direction of the liquid flow, leaving smaller and smaller holes for the flow at the bottom between the body of the trough and the baffles in the direction of flow. Application to the preparation of pitch devoid of water and foam according to a process operating continuously with usable flow rates.
