APPARATUS FOR MAGNETIC TREATMENT OF LIQUID Russian patent published in 1997 - IPC

FIELD: magnetic treatment of liquids. SUBSTANCE: in order to avoid deposits and reduce corrosion activity of produced liquid, on outer surface of ferromagnetic pipe T designed to transfer liquid stream, at least two pairs of constant annular magnets M are installed with gaps in each pair not exceeding width of annular magnet and at a distance between two pairs being no less than tripled width of annular magnets. Annular magnets are constructed of rectangular-cross-section rods, main surfaces of which are coupled with surface of pipe and face pipe axis with their analogous poles. Magnets are embraced with hermetic screen from outside. EFFECT: improved consumer's quality of liquid. 6 dwg, 1 tbl
