Definitions

  • the present invention relates to treatment of a flowing fluid, such as a liquid, gas or multiphase.
  • the flow may comprise one or more secondary substances suspended in the flow by primary dissolving action mechanism, for instance dipole molecules such as in water.
  • the secondary substance may also be a "pollution" of additional substance(s), for instance a gas such as air (nitrogen, oxygen, CO2) and/or a solid phase, such as colloidal suspended particles in the flow.
  • the solid phase particles may be suspended by a suspension mechanism of typically electric double layers, so called zetapotential suspension mechanisms. Examples are particles of clay, heterogenous bulk precipitated limestone, and other colloid or small particles typically present in substantially all natural water-supplies.
  • the polarization together with phenomena of additional forces arising from different magnetic susceptibility of flowing multiphase substances as well as a tentative integrated flow-regime- controller can then be tuned according to the flowing liquid properties in question to cause manipulation of say surface tension as well as controlled suspended minute precipitation, offset in pH and dissolved gases of the liquid.
  • This is, typically, only a temporary effect which diminishes after time depending actual flowing liquid mixture in question and the effect might last from milliseconds to days depending actual composition of the flow and related parameters like temperature and pressure of the flow in question.

  • a parallel additional mechanism for establishing an adjusted chemical equilibrium might arise from the offset gaseous balance inside the water (for instance extracted CO2 in the vortex core), resulting in an increase of local pH of the peripheral liquid phase and thereby causing supersaturation of for instance a calcium loaded ground water.

As shown in Fig. 3, the flux line bridges a flowthrough gap 7, arranged between the first guide body 3 and the second guide body 5. Furthermore, the first and second guide bodies 3, 5 narrow towards the flowthrough gap 7. In this manner, the magnetic field is concentrated when bridging the flowthrough gap 7.

  • the fluid flow that passes through the treatment arrangement 10 will thus be exposed to the magnetic field at the flowthrough gap 7.
  • the bulk of dipoles in the water will tend to align or polarize according to the induction forces generated by exposure to the magnetic field.
  • the degree of bulk-alignment or polarization will depend on the field strength of the magnetic field, and the corresponding magnetic forces will depend on the sharpness of the field-gradient as well as flowthrough speed.

In this manner, the first and second guide bodies 3, 5 are secured and aligned with respect to the flow guide 15.
  • a flow entering from the left towards the right, as illustrated with the arrows, will enter the cavity 13 through the flowthrough gap 7, and will thus be exposed to the magnetic field that bridges the flowthrough gap 7.

  • the first guide body 3 is formed as a flow inlet (or alternatively a flow outlet). As illustrated with arrows, the flow enters through an inlet section 3e of the first guide body 3. From the inlet section 3e, the flow is distributed to a plurality of distribution channels 3f that lead to the inner cavity 13.
  • the flow continues through the flowthrough gap 7, arranged between the first guide body 3 and the second guide body 5, into a surrounding chamber 19. From the surrounding chamber 19, the flow proceeds further to an outlet section 15d.
  • the cross sectional flow areas of liquid flow-through channels are substantially equal. This is to not disturb the average flow speed of the flowing liquid as to minimize hydraulic pressure losses through the treatment arrangement 10.
  • An exception is the flowthrough gap 7 that might be typically of a smaller flowthrough cross section. This enhances flowthrough speed and thus increases electromagnetic induction forces.
  • inlet section and “outlet section” merely relate to the direction of flow in the shown embodiment, and that the direction of flow could also be oppositely directed.
  • the outlet section 15d is formed as a pipe with an inner bore. Inside the bore there is arranged a vortex-generating arrangement 21 .
  • the vortex-generating arrangement 21 provides a vortex in the liquid flowing downstream of it.
  • the vortex-generating arrangement 21 can comprise an attachment means connected to the inner diameter of the outlet section 15d. It further comprises an inclined vane that provides the vortex-configuration of the flow.
  • the vortex in this flow may remain inside an outlet pipe (not shown) along a length of about 250 to 1000 times the diameter of the outlet section 15d.
  • the outlet section 15d should preferably have an inner diameter that corresponds to the inner diameter of said outlet pipe.
  • One purpose is to obtain a pressure gradient to achieve an offset I disturbance of the liquid-dissolved gases. For instance, since the pressure at the center portion of a flowing vortex will be lower than at its periphery, dissolved gases present in the flow can in such flow regime be allowed to expand. When expanding, they re-allocate from the heavier density and centrifugal pressure at the periphery of the vortex towards the centre of the vortex. This causes a forced separation of gases from the flow in a time interval corresponding to the vortex length. This further triggers a secondary event, for instance a controlled bulk precipitation due to such separation.
  • Another purpose is to obtain a longitudinal-helix-stressed flow-pattern to, for instance in the case of water, maintain a certain changed/stretched polarisation of water molecules inside the bulk of the water (some similarity to Lord Kelvins droplet experiment showing how a voltage appears in a stretched water flow from a dripping faucet, or analogy of same concerning the definition of how surface tension manifests through intermolecular forces).
  • Both features may manipulate local solubilities of say salts present inside the water as well as corresponding dissolved gases in the water. This affects interlinking chemical reactions, like say the precipitation of a dissolved salt onto a suitable colloid flowing in the bulk of the water (for instance precipitation of calcite on a colloid).
  • the mechanism is at least partially governed by the degree of chemical saturation in the water, such as pH of the water. This might again in this way be controlled by the g-forces produced by the vortex, hence also a corresponding pressure gradient from the core of the vortex to the periphery of the vortex flow, manipulating the amount of say dissolved CO2 inside the water, as this is related to pH and local pressure inside the water and flow regime.
