Abstract
La présente invention concerne des filtres utilisés pour éliminer des débris de leau aspirée dans un système de tuyauterie. Elle a une application particulière dans les centrales nucléaires qui, après un accident de perte de liquide de refroidissement, doivent pomper de leau de refroidissement en retour dans le cur du réacteur depuis un bassin collecteur. Cette eau peut contenir différents types de débris qui doivent être éliminés avant que leau soit renvoyée dans le système de refroidissement du réacteur. Il existe des restrictions relatives à la chute de pression tolérée de part et dautre de la crépine et à lespace disponible pour installer cet équipement. La crépine à ailettes de la présente invention résout ces problèmes tout en maximisant la quantité de débris filtrés à partir de leau.
