Electromagnetic trap for ferromagnetic particles in a flowing fluid
Description
Electromagnetic trap for ferro-magnetic particles located in a flowing fluid, featuring a tubular circuit along a part in a non-magnetic material having an inlet duct and two concentric outlet ducts, defining between them an annular area. This tubular circuit is enclosed in electric coils evenly spaced over its length and supplied with multiphased alternating current so as to induce, according to the axis of the tubular circuit, a sliding electromagnetic field moving in the same direction as the fluid. The invention particularly applies to the purifying of aqueous corrosion products from the steels of boiler circuits, specially of the primary and secondary systems of water-cooled nuclear reactors

Piege electromagnetique pour particules ferromagnetiques situees dans un fluide en ecoulement, caracterise en ce qu'il est constitue d'une partie de circuit tubulaire en un materiau non magnetique ayant une conduite d'entree et deux conduites de sortie concentriques, definissant entre elles une zone annulaire, ledit circuit tubulaire etant entoure de bobines electriques regulierement reparties sur sa longueur et alimentees en courant alternatif polyphase de facon a induire, selon l'axe du circuit tubulaire, un champ electromagnetique glissant de meme sens que l'ecoulement du fluide. L'invention s'applique plus particulierement a l'epuration des produits de corrosion aqueuse des aciers des circuits de chaudiere, en particulier des circuits primaire et secondaire de reacteurs nucleaires refroidis a l'eauAdditional details
