Baffle pipe segment, injector device and dissolving installation

A baffle pipe segment (1) as obstacle in a flow of a target liquid through the baffle pipe segment (1), comprising a baffle element (3) arranged in the path of the target liquid, wherein a slit (14) for passage of the target liquid is formed between a segment hull (8) of the baffle pipe segment (1) and the baffle element (3). The baffle element (3) comprises at least one first positive curvature (3a) towards the input side. The slit (14) is delimited by an inner wall (14a) and an outer wall (14b), wherein the inner wall (14a) is formed by a wall section of the baffle element (3) and the outer wall (14b) of the slit (14) is formed by a section of the segment hull (8). The slit (14) extends in a perpendicular direction to the longitudinal axis (z) along a section of the circumference of the segment hull (8). And an injector device (7) with such a baffle pipe segment (1) and a dissolving installation (50) with such an injector device (7).
