The invention relates to a UV-irradiation device for treating fluids, comprising an improved device for cleaning the surfaces of the jacket tubes. The UV-irradiation device comprises a number of lamp units, each having a radiation source and a jacket tube (3) that surrounds said radiation source, the lamp units being essentially cylindrical and a cleaning device, which has cleaning elements (1) that encompass the jacket tubes (3) in the form of a ring. At least one cleaning element (1) is allocated to each jacket tube (3) and the cleaning elements (1) of at least one drive unit can be displaced in the longitudinal direction of the jacket tubes (3). The cleaning elements have an axially delimited annular chamber, which is open towards the surface of the jacket tubes. At least one ring consisting of a rubber-type elastic material lies in said chamber. The internal diameter of said ring in an unstressed condition is less than or equal to the external diameter of the jacket tube.
L'invention concerne un dispositif d'irradiation UV conçu pour le traitement de fluide et comportant un dispositif amélioré destiné à nettoyer les surfaces de tubes de gainage. Le dispositif d'irradiation UV comprend : des unités de lampe comportant respectivement une source de rayonnement ainsi qu'un tube de gainage (3) enveloppant ladite source de rayonnement, les unités de lampes étant sensiblement cylindriques ; et un dispositif de nettoyage pourvu d'éléments de nettoyage (1) entourant les tubes de gainage (3) à la manière d'un anneau, chaque tube de gainage (3) étant associé à au moins un élément de nettoyage (1) et les éléments de nettoyage (1) pouvant être déplacés par au moins un organe de commande longitudinalement aux tubes de gainage (3). Les éléments de nettoyage comportent un espace annulaire à délimitation axiale présentent une ouverture orientée vers la surface des tubes de gainage. Cet espace comporte au moins un anneau constitué d'une matière élastique de type caoutchouc et dont le diamètre intérieur est, à l'état relâché, inférieur ou égal au diamètre extérieur du tube de gainage.
