Definitions

  • This invention relates to the production of gas mixtures containing air or oxygen and ozone. It is an object of this invention to provide means whereby the production of ozone and/or gas mixtures containing ozone is improved in several respects.
  • mixtures of 'airor oxygen and ozone have been produced by subjecting air or oxygen to electrical discharges taking place between pairs of electrodes, between which are arranged certain dlelectrics of fiat, curved,'tubular or other form.
  • the aim of the present invention is to comply with these four requirements at lowest cost.
  • the invention provides a new ozonizer belonging to the class having concentric electrodes and dielectrics.
  • the essential features of the device are (1) concentric electrode and dielectric members respectively formed from flexible metal or ⁇ fiexible insulating sheets rolled up successively one on the other; (2) electrodes cooled by a liquid the hydrostatic pressure of which actingon the fiexible electrode surfaces, perfects the contact of these surfaces with those of the corresponding dielectrics.
  • Fig. 1 is a vertical, axial section
  • Fig. 2 is a partial, horizontal, cross section along the line A-A in Fig. 1.
  • the ozonizer may be constituted by one preferably cylindrical element or by several preferably cylindrical elements arranged in parallel relation, which can be enclosed in a single metal box, and ied with singlephase, altcrnating current. They may also be delta-connected or star connected and fed with a three-phase current at a frequency of 42/50 cycles or high frequency.
  • Each element constituting an independent unit vertically mounted within the metal box i, comprises' two cylindrical dielectric bodies 2 and 3, each consisting of one or several sheets of a suitable insulating material (micanite, which is an insulating sheet comprising plates made by overlapping mica splittings and bonding them with a suitable adhesive, synthetic resins or the like).
  • a suitable insulating material such as mica, which is an insulating sheet comprising plates made by overlapping mica splittings and bonding them with a suitable adhesive, synthetic resins or the like.
  • These sheets of gauged thickness are rolled up in cold or hot condition according to their nature, and thickness, and radius or curvature as follows.
  • One or several sheets are rolled up on the outer surface of the body 6 to cover it. If one sheet only is rolled up the body 2 will take the form of a tubular surface cut on a longitudinal line; if several sheets are rolled up contiguously the body 2 will take the form of a tubular surface cut on several longitudinal lines (one for each sheet).
  • several spacing members 5 are fixed, each consisting of a band of insulating material having constant thickness and of length equal to the height of the body 2.
  • Each longitudinal cut line of the body 2 is covered by one of the said spacing members.
  • On the surface of these spacing members one or several sheets are rolled up to form a body 3 similar to the body 2 taking care that each of the cut lines of the tubular surface of the body 3 coincides with the axis of a spacing member 5.
  • Each element further comprises two concentric electrodes 6 and '1, constituted by tubular surfaces of a thin sheet of brass, Copper or some other suitable material.
  • the inner electrode 6 is closed at both ends by a welded bottom 8 so as to contain a cooling liquid and constitutes the mandrel around the outer surface of which is Wound the insulating material 2 With a tin-foil a between them, which is cemented on the insulating body.
  • the outer electrode 'i is formed by a thin sheet of Copper, brass or some other material wound around the outer insulation cylinder 3 with a thin sheet of tin b cemented to the outer surface of the cylinder 3 between the parts.
  • the edges of the joint of the metal sheet are welded together, a bottom made of a metal sheet 9 and welded to the end surface of the electrode T, rests on the bottom of the box l.
  • the unit enclosed in the outer electrode 'I-S is immersed in the body of a cooling liqud, preferably oil, contained in box I.
  • the liqud contained in the inner electrode 6 and in the box I can be cooled by any convenient cooling system.
  • FIG. 1 shows an example of a cooling system consisting of a cold water circulating ooiled pipe I'I immersed in the liquid contained in the box l; the cooled liquid is aspirated from the box l by the pump 10 which forces it through the pipe !2 into the inner electrode S from which it flows again into the box I through an overfiow pipe !3.
  • the inner electrode 6, as Well as the outer electrode T are made of thin and fiex'ible metal sheets, so that, in the inner electrode 6, the hydrostatic pressure of the cooling liquid (from the inside towards the outside).
  • the hydrostatic pressure of the cool: ing liquid (from the outside towards the inside) perfects the contact of the electrode T' with the outer surface of dielectric 3 around which the electrode is wound.
  • the exhaust, pipe M for the ozonized air is made of a non-oxidizable material. It extends through the electrode 6 andits bottom, and is connected to the apparatus to be supplied with the ozonized gas.
  • Dry air or oxygen ⁇ is forced into the box, l through a pipe !5 which terminates, above. the cooling liquid ⁇ level so that the air or oxygen is obliged to'fiow through the free spac'ebetween the surfacestof the dielectrics. -This space, in
  • ozone which electric discharge occurs to form ozone is represented by an annular space divided into several channels by the spacng members.
  • the flow of air or oxygen is thus divided into streams passing through each of the said channels which are re-unted in the ozone chamber 16. From this chamber !6 ozonized gas, escapes through the exhaust pipe !4 which, is connected to the ,apparatus to be, red with the ozonized gas.
  • the air-tight cover !8 of the ozonizer box. is provided with a Window !9 allowing an operator to watch and control the uniformity of the discharges and the distribution of the oil on the electrodes.
  • a tubular ozonizer element comprising in combination, an inner tubular electrodehaving a wall and a bottom ormed from'thin and flexible sheet metal to provide a fiuid-retaining eniclosure, two concentric dielectric members each formed by at least one flexible insulating sheet arranged to define a tube with the longitudinal edges of said sheet being in sealed relationwith the body of said tube, the inner of said members overlying the outer surface of the said innerelectrode, spacing means positioned upon! said inner dielectric member, said spacing means extending the entire length of the'axs of said 'member', the other of said dielectric members overlying the outer surface of said spacing means, an inner tubular electrode having a wall and a bottom ormed from'thin and flexible sheet metal to provide a fiuid-retaining eniclosure, two concentric dielectric members each formed by at least one flexible insulating sheet arranged to define a tube with the longitudinal edges of said sheet being in sealed relationwith the body of said tube, the inner of said members overly
