Definitions

  • My invention relates to the magnetic treatment of mineralized water and has particular reference to an improved geometry of magnets that more effectively treats or conditions water to increase its apparent softness.
  • Feed water for boilers and hot water heaters has been magnetically treated for decades to reduce boiler scale, heater deposits and water pipe deposits.
  • Feed water has been subjected to various configurations of magnetic fields, both steady fields and alternating fields.
  • This magnetic treatment has been effective to greater or lesser degrees in preventing boiler scale and heater deposits and deposits in water pipes. While the chemistry and electronics of magnetic field effects on dissolved and suspended minerals has not been precisely determined, the magnetic treatment causes the mineral content to remain in suspension rather than deposit out as scale. In the case of boilers the accumulated suspended minerals are continuously or periodically flushed out by flushing the boiler water.
  • This magnetic treatment is generally less expensive than ion-exchange treatment of feed water or additive chemical treatment of feed water.
  • Municipal water systems are generally the source of water for boilers. No boiler can operate efficiently or dependably if its heat transfer surfaces are allowed to foul with scale. Yet, most municipal water systems provide water that contains scale-producing minerals. The major dissolved materials in water are silica, iron, calcium, magnesium, and sodium compounds. Metallic constituents occur in various combinations with bicarbonate, carbonate, sulphate, and chloride radicals. Scaling occurs when calcium or magnesium compounds in the water precipitate and adhere to the internal surfaces of the boiler. These scaling compounds become less soluble as temperatures increase, causing them to separate from solution. The result is overheating of boiler tubes, followed by failure and equipment damage. This same scaling occurs in the heater and pipes of hot water heater systems. Unless these scaling deposits can be reduced, they result in heater failure and reduced carrying capacity of scaled-up pipes.
  • Fig. 1 is a three-dimensional view of piping passing through a permanent magnet in vertical section.
  • Fig. 2 is a three-dimensional view of the magnet and pipe of Fig. 1.
  • Fig. 3 is a schematic diagram of a direct-current coil passing around a pipe to create a magnetic field in the pipe.
  • Fig. 4 is a three-dimensional view of the commercial embodiment of the direct-current coil of Fig. 3.
  • Fig. 5 is a schematic sectional view through the magnets of Figs. 1 and 4 showing the concentration of lines of flux in the center of the conduit through the magnets.
  • Fig. 6 is a schematic end view of the magnet of Fig. 5 showing the manner in which the lines of flux concentrate in the conduit portion of the magnet.
  • pipes 11 and 12 are connected by a pipe 13 provided particularly in accordance with the invention.
  • the pipe 13 may be secured to the pipe sections 11 and 12 by any suitable means such as couplings 14.
  • Pipes 11, 12, and 13 form part of a continuous conduit for raw water leading to a boiler or to a water-heating system. Disposed about the pipe 13 prior to its coupling to pipe lengths 11 and 12 are a plurality of ring-shaped permanent magnets 16, 17, 18, and 19, which are all axially magnetized, that is, along an axis parallel to the pipe 13. While any suitable permanent magnet material may be used, I presently prefer, for purposes of manufacturing economy, ceramic magnets.
  • the pipe 13 is made of non-magnetic material and may be metal or plastic or glass or other nonferrous materials, and I presently prefer glass or plastic to eliminate any electrical effects on the water due to dissimilar metals being present.
  • the interior of the conduit 13 should be as smooth as commercially feasible to avoid any turbulence in the flow, and in this connection the couplings 14 should be of such construction as to minimize any turbulence in the flow.
  • Each ring magnet 16, 17, 18, and 19 is oriented with the adjoining magnet or magnets so that there is a continuous magnetic field from. north on the left to south on the right as viewed in Fig. 1. This stack of ring magnets develops a magnetic field, which is shown in schematic form in Figs.
  • a schematic magnet 20 of hollowcylinder construction has an axial hole 21 through it, and lines of flux 22, 23, 24, and 25 emanate from the ends of the magnet 20 to pass through the hole 21.
  • lines of flux 22 emanating from the farthest radial area pass toward the center of the bore 21 and that the next lines 23 emanating from the ends closer to the bore take a path to one side of the center of the bore 21; that the lines 24 that are closer to the bore take a path fairly close to the bore edge and that the lines 25 emanating close to the bore follow the interior of the bore 21.
  • FIG. 2 this illustrates in full outline the magnet of Fig. 1 shown in section.
  • a dimension L for the length of the magnet which is designated by the numeral 15.
  • a dimension D for the diameter of the magnet 15
  • the geometry is so chosen as to maximize the lines of-flux thru the axial hole compared to the flux lines thru the air on the outside of the magnet. Also the environment of the magnet must be selected not to interfere with this maximization of axial flux.
  • the magnet length L must be greater than one-fourth of the diameter D for the best water-conditioning. I have also found that if the length of the ferrite magnet is more than about two times the diameter, then there is very little added flux strength because of this added length.
  • the diameter C of the pipe conduit passing through the magnet which is the same as the inside diameter of the hole through the magnet, of course, has a bearing on these length and diameter dimensions, and these length and diameter ratios apply generally when the conduit dimension C is one-half of D or smaller.
  • a conduit 30 has a coil of wire 31 wrapped tightly about the conduit 30, and this is energized by a battery 32 passing direct current through the coil.
  • the coil generates a steady magnetic field which is identical in all respects to the magnetic field of the permanent magnets and generates lines of flux as illustrated in Figs. 5 and 6.
  • Shown in Fig. 4 is the commercial version of the schematic Fig. 3, wherein the conduit 30 has a multilayer coil 33 wrapped around it and this coil 33 will generate a north pole at the left end as indicated by the letter N and a south pole at the right end as indicated by the letter S.
  • the coil is energized by any suitable source of direct current, and there is shown schematically a directcurrent generator 34 driven by a AC-motor 36 or any other suitable motor, which in turn delivers current to the coil 33 through conductors 37 and 38.
  • the water should flow through the magnets from north to south. If it is desired to increase the apparent hardness of the water, then the water should flow through the magnets from south to north. When the flow is from north to south, then the apparent softening also seems to loosen some boiler scale already formed.
  • the term "apparent softening" is used to denote the effect on the dissolved material. My apparatus does not remove any dissolved material, and a chemical analysis on a dry basis of water treated by my apparatus would be the same as the untreated input water. However, there is a chemical or electronic change in these scale-producing materials so that they do not deposit out as readily as the materials in raw water. The same analysis applies to my water treatment to increase the "apparent hardness", except in this case scaling is increased and the usefulness is for defoaming and other uses of hard water.

Abstract

Generalement l'eau d'alimentation des chaudieres et des radiateurs a eau chaude contient des mineraux qui produisent des depots calcaires dans la chaudiere, les radiateurs et les conduites d'eau. Un traitement d'une telle eau consistant a la faire circuler au travers d'un champ magnetique a montre son efficacite plus ou moins grande dans la prevention des depots calcaires dans la chaudiere, dans les radiateurs et dans les conduites d'eau. On a determine qu'un champ magnetique efficace pour un tel traitement d'eau est constitue par un champ ou les lignes de flux sont paralleles a la direction d'ecoulement de l'eau. Ceci se verifie dans un dispositif possedant un trou axial (21) utilisant un aimant permanent ou un electro-aimant (20). Le dispositif possede une conduite d'eau (13) non magnetique s'adaptant etroitement dans le trou axial (21) de l'aimant (20). L'aimant (20) est magnetise axialement et la structure magnetique est disposee de maniere a porter au maximum le flux magnetique (22-25) dans le trou axial (21). Une des utilisations principales du dispositif est le traitement magnetique de l'eau d'alimentation pour chaudieres et radiateurs a eau chaude, consistant a reduire les depots calcaires dus aux mineraux presents dans l'eau d'alimentation.
