Definitions

  • the present invention relates to apparatuses producing ozone, or ozonizers, of the type comprising a plurality of cylindrical silent discharge elements each of which consists of an outer metal sleeve and a glass tube disposed within said sleeve, the inner face of said tube being at least partially metallized.
  • the metallized layer and the metal sleeve are respectively connected to one of the ends of the high tension winding of a transformer and constitute the armatures of a capacitor between which is produced from a given voltage a silent discharge phenomenon which converts a part of the oxygen of the air owing between these armatures into ozone.
  • the yield of the ozone is of course a function of the maximum voltage it is possible to apply between the two armatures.
  • parasitic effects, such as sparks are produced in the regions of concentration of the lines of force which thus limit the operational characteristics of the apparatuses to values inferior to those which could theoretically be anticipated.
  • the object of the invention is to improve the apparatuses of the aforementioned type.
  • the ozonizer element according to the invention comprises, in said glass tube, in roughly facing relation to the end of said metal sleeve, a metal deecting ring having a roughly cylindrical portion in contact with said metallized layer and a curved remaining portion, the concavity of said curved portion facing the interior of said tube, whereby the distance between said ring and said wall of said tube increases progressively.
  • the curved portion of the deflecting ring has a section of parabolic shape.
  • FIG. 1 is a sectional view of an ozonizer element provided with a deilecting ring according to the invention.
  • FIG. 2 is a perspective view of said ring removedifrom the silent discharge element shown in FIG. 1.
  • FIG. 1 shows a silent discharge element of a tube ozonizer of known type.
  • Such an element comprises mainly a cylindrical metal tube 1 in which is disposed a concentric electrode 2 which is also cylindrical and consists of a glass tube 2a, the cylindrical portion of which is covered with a conductive layer 2b.
  • the metal tube 1 is ared at 1iEL and 1b so as to constitute :a field deector and the glass tube 2a extends beyond the two ends of the metal case.
  • One end 3a is closed and has a conical shape and the other end 3b is open and corrugated.
  • the tube 1 is connected to the other terminal of this high tension winding.
  • the end 3b of the tube 2 is provided with a deecting ring 6 which has a cylindrical portion 6a and a curved portion 6b whose concavity is directed inwardly of the tube 2.
  • the portion 6a of the ring is in contact with the conductive lm 2b.
  • the curved portion of the ring has preferably a longitudinal section in the shape of arcs of a parabola. It is split at 7 (FIG. 2) throughout its length so as to enable it to be introduced in the tube 2 in such manner that, once it is mounted in the tube, it forms a minimum clearance which is almost nil between the two edges of the split 7.
  • This ring is preferably constructed from previously annealed polished steel so as to have good elasticity and has a thickness of about a few tens of a millimetre.
  • the advantage of the device according to the invention is important.
  • the presence of the deecting ring 6 at the end of the tube 2 precludes a peak effect at the end of the electrode constituted by the metal layer 2b or, more precisely, increasing the voltage at which this peak elfect is produced. This is due to the fact that the separation between the conductive material and the dielectric is achieved in a more progressive manner owing to the curved portion 6b of the ring.
  • the length of the corrugated insulating portion of the glass tube outside the tube 1 has to be increased relative to the length in conventional apparatuses.
  • an ozonizer element comprising a metal outer sleeve and a glass tube located within said sleeve and having an inner face which is at least partially metallized; a metal dellecting ring in said glass tube in roughly facing relation to the end of said metal sleeve, said ring having a roughly cylindrical portion in contact with said metallized layer and a curved remaining portion, the concavity of said curved portion facing the interior of said tube, whereby the distance between said ring and said wall of said tube increases progressively.
  • Au ozonizer element comprising Vincombination a metal outersleeve, a glass tube located within said sleeve and having an inner face which is at least partially metallized and a metal deflectiug ring in said glass tube in roughly facing relation to the end of said metal sleeve, said 4ring having a roughly cylindrical portion in contact with said metallized layer and a curved remaining portion, the concavity of said curved portion facing the interior extending throughout y 4 l of said tube, whereby the distance between said ring and said wall' of 'sid tube increases progressively.
