DEVICE FOR MAGNETIC TREATMENT OF THE LIQUIDS Russian patent published in 2007 - IPC C02F1/48 

FIELD: petroleum industry; devices for magnetic treatment of the liquid.

SUBSTANCE: the invention is pertaining to the field of petroleum industry, in particular, to the devices for magnetic treatment of the liquids and may be used at operation of the oil-wells for prevention of sedimentation of the asphaltic- tar- alkanes and the inorganic salts on the pumping equipment. The device includes the cylindrical body with the coaxial assemblies of the permanent magnets. In each assembly the permanent magnets are alternating by their poles in the circumferential and axial direction. The magnets are built-in in the cylindrical shells made out of the open-cellular metallic foam, which have been fulfilled from the magnetically-soft material, for example, of a nickel. The diameter of the cell of the open-cellular metallic foam changes within the ranges of 2...5 mm. The device ensures the orthogonal directivity of the alternating magnetic fields to the stream of the liquid and the increased efficiency of the liquid treatment due to the increased duration of its stay in the magnetic field.

EFFECT: the invention ensures the orthogonal directivity of the alternating magnetic fields to the stream of the liquid, the increased efficiency of the liquid treatment.
