FLOW STRAIGHTENER FOR CLOSED PIPELINES

摘要

The invention relates to a conduit for a UV-irradiation apparatus, in which the UV-irradiation apparatus (6) is arranged in a closed conduit (1, 3) and an intake cone (2) is provided upstream of a UV reactor (6) in the flow direction. The intake cone, as part of the wall of the conduit, increases the cross-sectional area of the conduit from an infeed pipeline cross-sectional area to a cross-sectional area of the reactor. A flow straightener (10) having at least one inner first guide element (11) and at least one outer second guide element (13) is arranged in the intake cone (2), wherein the inner guide element (11) is a substantially circularly cylindrical pipe and the outer guide element (13) runs substantially parallel to the outer wall and is arranged spaced from the outer wall.
