DEVICE FOR MAGNETIC TREATMENT OF LIQUID Russian patent published in 2002 - IPC

FIELD: devices for magnetic treatment of liquids; prevention of formation of asphalt gum paraffin deposits in oil production equipment in the course of treatment of water pumped into wells in oil recovery; protection of water and heat supply systems against scaling; reduction of corrosion activity of water systems. SUBSTANCE: proposed device has body-pipe line made from magnetically soft material and magnetic system consisting of radially magnetized permanent magnets mounted along length of body at alternating directions of magnetization; it is provided with passage for liquid between outer surface of magnetic system and inner surface of body. Located between magnets are axially magnetized magnets with alternating directions of magnetization. Polarities of poles of radially magnetized magnets facing inner surface of body- pipe line coincide with polarities of poles of axially magnetized magnets directed to them. Outer diameter of radially magnetized magnets is lesser than outer diameter of axially magnetized magnets. Fitted between axially and radially magnetized magnets are inserts made from nonmagnetic material. Axially magnetized magnets and inserts are sectional in construction. EFFECT: enhanced efficiency of treatment due to increased amplitude and gradient of magnetic field intensity. 5 cl, 6 dwg
