LIQUID MAGNETIZATION DEVICE Russian patent published in 1998 - IPC

FIELD: magnetic treatment of water and water supply systems, prevention of deposition of hard salts on heat exchange surfaces in heat power industry, chemical, petrochemical industries, oil excavation and agriculture. SUBSTANCE: liquid magnetization device incorporates magnetic unit and body with shaft of magnetic material. Novelty of device lies in installation of magnetic unit inside body and in its manufacture in the form of cylinder that includes magnetic circuit that carries radially magnetized permanent magnets put with alternation of polarity which pole pieces form working clearance together with body and nonmagnetic material distance pieces located between them. Shaft is passed through hole made in magnetic circuit. Cross-section of magnetic circuit in sections between adjacent magnets has predominantly section smaller than that found from relation S=Φ_mf/B_sat, where Φ_mf is magnetic flux between adjacent magnets; B_sat is saturation inductance of material of magnetic circuit. EFFECT: expanded application field, increased functional efficiency. 1 cl, 2 dwg
