Abstract

Dispositif de stérilisation à circulation comprenant : des modules d'émission de lumière ultraviolette (1), une première unité de stérilisation (2), une seconde unité de stérilisation (5), une unité de raccordement (6) et une structure de génération d'écoulement tourbillonnaire (3). La présence de la structure de génération d'écoulement tourbillonnaire (3) dans le dispositif de stérilisation à circulation permet de produire un écoulement d'eau en spirale, de sorte que la survenance d'écoulements courts et d'écoulements turbulents est réduite; le courant d'eau monte ou descend en spirale sur les parois internes des cavités de stérilisation (21, 51), de sorte que le trajet de l'eau est allongé, ce qui permet d'augmenter la durée de rétention de l'eau et d'améliorer l'effet de stérilisation.
