FLUID CIRCULATION SYSTEM FOR CIRCULATING AN AMOUNT OF FLUID COMPRISING A MAGNETIC SEPARATOR FOR SEPARATING SUSPENDED PARTICLES HAVING FERROMAGNETIC PROPERTIES, AND CORRESPONDING METHOD
A fluid circulation system for circulating an amount of fluid, susceptible of containing suspended particles (21; 121; 221) having ferromagnetic properties, between heat exchangers is provided with a magnetic separator (1; 101; 201). The magnetic separator (1; 101; 201) includes a collection chamber (3; 103; 203) having an inlet (5; 105; 205) for receiving the flow of fluid and an outlet (7; 107; 207) for allowing the fluid to flow out of the collection chamber. A fluid flow path is defined between the inlet (5; 105; 205) and the outlet (7; 107; 207), including an interior (9; 109; 209) of the collection chamber (3; 103; 203). A substantially tubular sleeve (11; 111; 211) is positioned in the fluid flow path interiorly of the collection chamber (3; 103; 203) and has a fluid tight interior (12; 112; 212). A magnet device (12; 113; 213) is accommodated within the fluid tight interior (12; 112; 212) of the substantially tubular sleeve (11; 111; 211) for creating a magnetic field on at least a first exterior portion of the substantially tubular sleeve (11; 111; 211). Means (15, 19; 115, 119; 215, 219) are included in the magnetic separator (1; 01; 201) for selectively eliminating the magnetic field on the first exterior portion. The means for selectively eliminating the magnetic field (15, 19; 115, 19; 215, 219) comprise an auxiliary sleeve (15; 115; 215) of ferromagnetic material that can become interposed between the magnet device (13; 113; 213) and the substantially tubular sleeve (11; 111, 211) to short circuit the magnetic field.
