Abstract

A process and a device for the magnetic treatment of fluid as the fluid moves in successive magnetic fields, including a sheet (1) having adjacent transverse bands (2) each of the same width (3) The bands (2) are each charged with magnets oriented alternatively NS/SN perpendicularly to the plane of the sheet so that successive transverse bands adjacent to each other present upper polar faces alternately having polarities S, N, S, N . . . S.N. Each pair of two adjacent bands being related to each other such that the width of the pair is equal to a full wavelength of alternately encountered magnetic fields with a polarity varying periodically, of which the half wave length is equal to the width of one of the adjacent bands (2) when particles (4) are circulated in a fluid relative to the bands (2) whereby relative displacement of the particles (4) with respect to the sheet subjects the particles (4) to magnetic fields which alternate in time of which the frequency increases with relative speed. The fluid is displaced in relative movement with respect to the device so that the trajectories of the particles of the fluid are substantially at right angles to the loop lines of force of the fluid, and the fields created by magnetized lines of the adjacent bands of alternate polarities are spaced apart from one another by a half wave length equal to the distance between successive N-S poles.

Claims

1. A device for the magnetic treatment of a fluid flowing through a volume comprising:

a cylindrical tube for defining said volume, said tube having a central axis;

a flexible cylindrical sheet means coaxially positioned within said tube having radially inner and outer surfaces, said sheet means including adjacent magnetized bands extending coaxially about said axis, said adjacent bands forming part of said sheet means and being regularly spaced apart from each other and being each of the same width as measured in a direction parallel to said axis;

wherein each of said bands contain a plurality of small magnets polarized in a single direction normal to said inner and outer surfaces of said sheet means, each said band including a cylindrical inner polar face of a first polarity and a cylindrical outer polar face of a second polarity opposite said first polarity, wherein the polarity of the inner polar face of one of said bands is opposite to that of the polarity of the inner polar face an adjacent band and the polarity of the outer polar face of said one band is opposite to that of the polarity of the outer polar face of said adjacent band;

each pair of two adjacent bands being related to each other such that a width of one band of said pair of two adjacent bands is equivalent to a half wavelength, and said one band which is adjacent to the other band is the same width as that of the other band and the width of said one band plus a width of said other band is equivalent to a full wavelength of alternately encountered magnetic fields with a polarity varying periodically, of which the half wave length is equal to the distance between a center point on each said width of each said one or said other of said two adjacent bands of successive bands of opposite polarities when particles are circulated in a fluid relative to said bands whereby relative displacement of the particles with respect to said sheet means subjects said particles to magnetic fields which alternate in time of which the frequency increases with relative speed; and

whereby said fluid when being displaced in relative movement with respect to said sheet means and said magnetized bands provides trajectories of particles in the fluid substantially at right angles to loop lines of force of the fluid, and magnetized fields created by magnetized lines of said adjacent bands of alternate polarities spaced apart from one another by said half wave length which is equal to said width and to the distance between successive N-S poles.

2. The device of claim 1, wherein an outer surface of said tubular sheet means is fixed onto an inner surface of said tube.

3. The device of claim 1, including means for fixing the flexible sheet means such that an outer surface of said tubular sheet means is spaced from an inner surface of said tube.

4. The device of claim 1, wherein said tubular sheet means is formed of a flexible magnetic polymer.

5. A method for magnetically treating a fluid comprising the steps of:

providing the device according to any one of claims 1 to 4;

passing said fluid through said tube and along said sheet means to magnetically treat said fluid.
