Abstract

L'INVENTION CONCERNE UN PROCEDE ET UN DISPOSITIF DE REGULATION DU FONCTIONNEMENT D'UN FILTRE ELECTROMAGNETIQUE TRAVERSE PAR UN FLUIDE CHARGE DE PARTICULES FERROMAGNETIQUES. LE BOBINAGE DU FILTRE EST ALIMENTE PAR UN COURANT CONTINU D'INTENSITE INFERIEURE A L'INTENSITE DU COURANT DE SATURATION DU GARNISSAGE, DE TELLE SORTE QUE L'INTENSITE DE CE COURANT PEUT ETRE AUGMENTEE LORSQUE LES MESURES DE LA PERTE DE CHARGE DU FILTRE, DE LA VITESSE D'ECOULEMENT DU FLUIDE ET DE LA TEMPERATURE DE CE FLUIDE FONT APPARAITRE QUE L'EFFICACITE DU FILTRE EST INFERIEURE A UN NIVEAU DONNE. UN DISPOSITIF D'ALARME EST DECLENCHE LORSQUE L'INTENSITE DU COURANT ATTEINT UNE VALEUR MAXIMALE INDIQUANT QUE LE FILTRE DOIT ETRE DECOLMATE. APPLICATION NOTAMMENT A LA FILTRATION DE L'EAU DANS LE CIRCUIT PRIMAIRE DES REACTEURS NUCLEAIRES A EAU PRESSURISEE.THE INVENTION CONCERNS A PROCESS AND A DEVICE FOR REGULATING THE OPERATION OF AN ELECTROMAGNETIC FILTER THROUGH A FLUID CHARGED WITH FERROMAGNETIC PARTICLES. THE FILTER WINDING IS SUPPLIED BY A CONTINUOUS CURRENT OF LOWER INTENSITY THAN THE INTENSITY OF THE PACKING SATURATION CURRENT, SO THAT THE INTENSITY OF THIS CURRENT CAN BE INCREASED WHEN MEASURING THE FILTER PRESSURE DROP, THE FLUID FLOW SPEED AND THE TEMPERATURE OF THIS FLUID INDICATE THAT THE EFFICIENCY OF THE FILTER IS LESS THAN A GIVEN LEVEL. AN ALARM DEVICE IS TRIPPED WHEN THE CURRENT INTENSITY REACHES A MAXIMUM VALUE INDICATING THAT THE FILTER MUST BE DISCOLMATED. APPLICATION IN PARTICULAR TO THE FILTRATION OF WATER IN THE PRIMARY CIRCUIT OF PRESSURIZED WATER NUCLEAR REACTORS.
