The apparatus for injecting one or more additives (4) into a flow (5) of a highly viscous liquid into which the additives are to be admixed comprises a supply member (3) for each additive. This supply member is releasably connected to a tube section (2) conducting the flow. Each of the supply members has a supply channel (30) for the additive which stands transversely to the direction of flow. The additives temporarily form separate phases which coexist with the phase of the highly viscous liquid after having been fed in. A wall section (1) which is oriented in the direction of flow and can be flowed about on both sides by the highly viscous liquid is associated in each case with at least some of the injection members. Its inner side (10), that lying nearer the centre of the tube, spans a surface on which the exit opening (35) of the supply member at least approximately lies. The wall section is provided downstream from the discharge opening as a spreading means (11) for the additive supplied.
Appareil servant à injecter un ou plusieurs additifs (4) dans un volume (5) de liquide très visqueux auquel des additifs doivent être intégrés. L'appareil comporte un dispositif d'injection (3) pour chaque additif. Ce dispositif est relié de façon non permanente à un tube (2) dans lequel coule le liquide. Chaque dispositif comporte un canal d'alimentation (30) en additif qui est placé en sens transversal par rapport à la direction de l'écoulement. Les additifs forment temporairement des phases distinctes qui coexistent dans le liquide en phase très visqueuse après y avoir été ajoutés. Une paroi (1), orientée dans le sens de l'écoulement, permet au liquide très visqueux de s'écouler de chaque côté d'elle et est associée dans chaque cas à au moins certains des dispositifs d'injection. La face intérieure (10) de la paroi, soit celle qui se trouve le plus près du centre du tube, occupe une surface près de l'orifice d'écoulement (35) du dispositif d'injection. La paroi se trouve en aval de l'orifice d'écoulement et sert à répartir (11) l'additif fourni.
