Definitions

• the invention relates to a device for treating a fluid, by ionization, in particular a combustible fluid, one of the preferred fields of application of the invention being the treatment of a fuel before its admission into an internal combustion engine. .
• a treatment device comprising a cylindrical chamber in which two electrodes are defined, one axial having the shape of a rod and the other constituted by the metallic internal wall of said chamber. A high voltage is applied between the two electrodes.
• This device can in particular be connected in the fuel supply circuit of an internal combustion engine, for example upstream of the carburetor in a gasoline engine or of the injection pump in a diesel engine.
• the invention aims to improve this type of device, making it possible to significantly improve the results.
• the invention essentially relates to a device for treating a fluid of the type comprising a circulation enclosure in which is defined an annular passage for said fluid, located between two coaxial electrodes and means for applying a high voltage between the two electrodes, characterized in that at least one of the electrodes is embodied by a conductive spiral winding.
• the two electrodes are constituted by coils of respective and coaxial spiral conductive wires; the pitch of the windings being substantially identical.
• the circulation enclosure is filled with dielectric particles, in particular glass beads.
• the fluid treatment device comprises an approximately cylindrical insulating and waterproof enclosure 11 in which is defined an internal sleeve 12, axial, open at one end 13 and closed at its other end 14 located in the enclosure 11
• the interior of the sleeve 12 is thus isolated from the rest of the enclosure in which a double annular passage is defined by virtue of an axial conduit 15 surrounding the greater part of the sleeve 12.
• This axial conduit extends beyond the wall transverse end 16 of the enclosure 11 to define a connecting piece 17 forming the inlet (or outlet) of the fluid to be treated.
• the other end 18 of the conduit 15 opens into the insulating enclosure 11 in the vicinity of its other end wall 23.
• This axial conduit therefore materializes in the enclosure 11 a first annular passage 19 of relatively small section, defined between the wall outer of the sleeve 12 and the inner wall of the conduit 15 and a second annular passage 20 of larger section, defined between the outer wall of the conduit 15 and the inner wall of the enclosure 11 itself.
• Another connection end piece 21 for the outlet (or inlet) of the fluid to be treated is defined radially in the enclosure 11, in the vicinity of its end wall 16.
• the annular passage 20 in which the essential takes place of the treatment is filled with small glass beads 22, which improves the efficiency of the device.
• the transverse wall 23 of the enclosure 11 which faces the end 18 of conduit 15 has an approximately frustoconical internal surface to avoid the formation of air pockets at this location.
• the enclosure 11 is made of glass, but the whole of the structure described above can be produced in any suitable dielectric material.
• two electrodes are provided, one 25 being housed inside the sleeve 12 and the other 26 outside the enclosure 11 itself.
• at least one of the electrodes 25, 26 is materialized by a spiral winding of a conductive wire, for example tungsten.
• the two electrodes are constituted by respective spiral windings having substantially the same pitch.
• the electrode 25 located in the sleeve 12 is wound on an insulating core 28, for example made of ceramic or polytetrafluoroetylene.
• This insulating core advantageously comprises a helical groove at its external surface (not shown) and the conductive wire constituting the electrode 25 is housed in this groove.
• the two electrodes are intended to be connected to the two poles of any high voltage source (not shown) direct or alternative, to create the aforementioned high field in the enclosure 11.
• a metal shield, not shown, can be placed around of electrode 26.
• the spiral shape of the electrodes 25 and / or 26 significantly improves the efficiency of the treatment, in particular each time it is applied to a hydrocarbon, with a view to reducing the fuel consumption in an internal combustion engine.
• the device which has just been described can be the subject of numerous variants without departing from the scope of the invention.
• Each duct would thus be connected by one end to one or the other of the transverse walls of the insulating enclosure 11 and would open freely at its other end into said enclosure, this arrangement thus defining a sort of labyrinth of circulation of the fluid at the inside the enclosure 11.
• the internal electrode could be produced by metallizing the surface of the insulating core 28 and then practicing threading on the metallized core, the threading operation automatically cutting the metallization into a spiral.
• the same process could be applied to produce the electrode 26 from a sleeve of insulating material with a diameter corresponding to that of the enclosure 11, internally metallized and then tapped.
• Metallization could also be carried out after the materialization of the screw thread at the surface of the insulating support corresponding to the condition of metallizing only the protruding parts of the thread.
