Flow rectifier for closed pipelines

摘要

A channel for a UV irradiation device, in which the UV irradiation device is disposed in a closed channel and an inlet cone is provided in the direction of flow upstream of a UV reactor, which, as part of the wall of the channel, increases the cross section of the channel from an incoming pipeline cross section to a cross section of the reactor, in which a flow rectifier with at least one inner first guide element and at least one outer second guide element is disposed in the inlet cone, wherein the inner guide element is a substantially circular, cylindrical pipe and the outer guide element runs substantially parallel to the outer wall and is disposed at a distance from the outer wall.

1. A channel for an ultraviolet (UV) irradiation device, in which the UV irradiation device is disposed in a closed channel, wherein a flow rectifier with at least one inner first guide element having two open ends and an axially extending fluid passageway defined therebetween, and at least one outer second guide element is disposed in the channel upstream of the UV irradiation device, wherein the outer second guide element surrounds the inner first guide element and the outer second guide element is disposed at a distance from an outer wall of the channel.
