Abstract

Un mode de réalisation de la présente invention concerne un séparateur d'humidité de type à aube de turbulence, qui est disposé dans un générateur de vapeur de réacteur, sépare l'humidité de la vapeur humide et fournit de la vapeur sèche à un côté turbine, le séparateur d'humidité de type à aube de turbulence comprenant une colonne montante et une aube de turbulence. La colonne montante comprend : un tube interne qui a un trajet d'écoulement de vapeur formé à l'intérieur de celui-ci, à travers lequel de la vapeur humide s'écoule à partir d'une partie inférieure et de la vapeur sèche est évacuée vers une partie supérieure et un trou de passage de film liquide qui est formé sur la circonférence de l'extrémité supérieure et à travers lequel passe un film liquide formé par des gouttelettes séparées de la vapeur humide ; et un tube externe qui est disposé de façon à entourer au moins la circonférence supérieure du tube interne et forme un tuyau de descente à travers lequel le film liquide qui a traversé le trou de passage de film liquide s'écoule vers le bas et est évacué. L'aube de turbulence est disposée rotative à une position prédéterminée dans le trajet d'écoulement de vapeur et sépare les gouttelettes au moyen de la force centrifuge de la vapeur humide se déplaçant le long du trajet d'écoulement de vapeur.
