Abstract
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.
Claims14
A UV irradiation device for treating fluids, comprising:
- a plurality of lamp units, each of which is provided with a radiation source, and a jacket tube that surrounds the radiation source, wherein said lamp units are essentially cylindrical;
- a cleaning device having cleaning elements that extend annularly around said jacket tubes, wherein at least one cleaning element is associated with each jacket tube, wherein said cleaning elements are displaceable in a longitudinal direction of said jacket tubes by at least one drive unit, and wherein each cleaning element is provided with an axially delimited, annular chamber that is open toward a surface of an associated jacket tube;
- and
- at least one ring disposed in each chamber, wherein said ring is made of elastomeric material and has a non-circular radial cross section, and wherein said ring, in a relaxed state, has an inner diameter that is less than or equal to an outer diameter of said jacket tube, wherein in the longitudinal direction of said jacket tube, said cleaning elements are provided with support means that are disposed adjacent to end faces of said ring and that are configured to counteract deformation of said ring upon actuation of said cleaning elements.
