The invention relates to a device for eliminating scale and for preventing the formation of scale in pipe systems through which a liquid, for example water, flows, in which arrangement the liquid is exposed to a magnetic field generated by a magnet coil, comprising an internal space which is formed
The invention relates to a device for eliminating scale and for preventing the formation of scale in pipe systems through which a liquid, for example water, flows, in which arrangement the liquid is exposed to a magnetic field generated by a magnet coil, comprising an internal space which is formed in a housing and which is circularly symmetrical to a housing axis, with a partition which subdivides the internal space into two chambers and which is arranged perpendicularly to the housing axis, which partition is arranged with a distance on all sides from the inside surface, limiting the internal space, of the housing, with an inlet opening at one chamber, formed in the housing, and with an outlet opening at the other chamber, formed in the housing, in which arrangement the inlet opening and the outlet opening are in each case opposite to the central area of the partition, with a magnet coil, which concentrically encloses the partition and which is arranged in an annular recess of the housing, for generating the magnetic field, and with an annular wall section which concentrically encloses the partition and which is provided between the magnet coil around this inner wall and closes off the internal space of the housing at its circumference located radially on the outside, the partition and the housing consisting of ferromagnetic material at least in an area surrounding the internal space.

A device for eliminating scale and for preventing the formation of scale in pipe systems through which a liquid flows in which device the liquid is exposed to a magnetic field generated by a magnet coil, comprising: (a) a housing having an internal space which is formed in said housing, said internal space being circularly symmetrical to a housing axis, (b) a partition positioned in said internal spaced in said housing, said partition subdividing the internal space into two chambers and arranged perpendicularly to the housing axis, said partition being arranged a distance from a housing inside surface that defines said internal space, (c) an inlet to one chamber, formed in the housing, (d) an outlet from the other chamber, formed in the housing, with the inlet and the outlet being in each case opposite to a central area of the partition, (e) said magnet coil concentrically enclosing the partition and being arranged in an annular recess of the housing, (f) an annular wall section concentrically enclosing the partition and being provided between the magnet coil and the internal space of the housing and limiting the internal space at its radially outwards located circumferential area, with the partition and the housing at least in its area surrounding the internal space being made of cast iron which is annealed after coasting and before machining the inside surface of the housing (1, 2; 101, 102) and the sides of the partition (14, 108), (g) with the housing (1, 2; 101, 102) being provided on its inside surface with a coating of a corrosion-resistant material having a high magnetic conductivity, with the partition (14, 108) being also provided on its sides with a coating of said corrosion-resistant material, (h) said annular wall section (26, 118) consisting of a non-magnetic material and having in the direction of the housing axis (S) a width which is larger than the smallest distance between the inside surface of the housing (1, 2; 101, 102) and an opposite surface of the partition (14, 108), and (i) a circuit (123, 124) for driving the magnet coil (25, 116) by a DC-current periodically changing its polarity and flowing through the magnet coil (25, 116) in a first direction during a first time interval (T1) and in a second direction opposite to the first during a second time interval (t).
