UV-irradiation device for treating fluids, comprising an improved cleaning device

摘要

A UV irradiation device for the treatment of fluids has an improved device for the cleaning of the surfaces of the jacket tube with a number of lamp units that each have a radiation source and a jacket tube that surrounds the radiation source, whereby the lamp units are essentially cylindrical. A cleaning device has cleaning elements that annularly extend around the jacket tubes 3. Each jacket tube has at least one cleaning element, and the cleaning elements are displaceable in the longitudinal direction of the jacket tubes by at least one drive unit. The cleaning elements have an axially delimited, annular chamber that is open towards the surface of the jacket tubes. At least one elastomeric ring is disposed in the chamber.
