ELECTRICAL APPARATUS FOR GEN ERATING OZONE. i
Application led April 12, 1924, Serial No. 706,048, and in Great Britain April 24, 1823.
This inventioni relates to improvements in electrical apparatus for generating ozone and the object of the invention is to so construct suchA an apparatus that a greater efficiency of output can be obtained from any given dimensions and/or weight of material' than by the methods at present in use and incidentally to simplify and strengthen the construction of such apparatus. f
According ozonator primarily consists in the construction of any suitable electrodes in a convolute form and in which either air or insulating material with distance or separating pieces or other suitable means for securing the nec- `es'sary air gap or aperture may be employed.
material are secured, formed or deposited aflexible electrode of electrically conducting material the length and width of which are determined by the capacity required aiid by the urpose for which, the ozonator is to be used? Y- Y The length and width of the insulating bands or strips is considerably greater than those of the electrodes so-as to` provide an .insulating margin aroundthe four edgesof the electrodes mounted on them.
In order to provide a suitable gap or aperture between the electrodes for. the passage of the atmospheric or other oxygen to` be ozonized several methods may be adopted such as the formation of ridges on one or both'sides .of the dielectrics by corrugating the latter, or by forming ridges on-the surface of the material during its'manufacture or` such ridges may be provided by separate pieces of suitable material secured in position. The aforesaid ridges in all cases are disposed transversely to the length of the band or strip.
Or alternatively, a suitable passage for the atmospheric or other oxygen to be ozonized may be-provided by so forming one or both of the flexible electrodes that such atmospheric or other oxygen may pass through 1t or-them and along and about the points ork arts of the electrode or electrodes which are in contact with the dielectrics.
to my present invention'thel In order that my invention maybe clearly' understood reference may now be had tothe accompanying sheet of drawing in which*- Figure '1 is a perspective fragmentary View of one form of element that may be 'employed for the construction'of an ozone generator and Figures 2, 3 and 4 are diagrammatic views of alternative lconstruction of similar elements whilst,
Figure 5 is a frontelevation of a complete apparatus and Figure 6 a side elevation of Figure 5 the upper half being in section.
Figure 7 is a plan and Figure 8 a section. on line of Figure 7 showing the con struction of a preferred form of electrode to an enlarged scale.
-Similar letters of'reference relate to like parts in all the figures the drawing.
Referring to Figures 1 2 5 and 6 it will be 'seen that in one constructional form of an ozone generator according to this invention I take the twobands or strips of iexible ozone resisting insulating material a-b on one sideof each of which a 4flexible electrode c is secured andV upon these bands distance pieces of insulating material d are transversely disposed and fastened thereto by any lconvenient means. One such band or strip is then placed on top ofV and parallel to the other with the similar surfaces facing up'- wards as shown in Figures 1 and 2 (in the latter the electrode being depicted by the' dash line) and the two superimposed strips are rolled lor convolved together and thc whole secured in a suitable pipe ring or frame e as shown in Figures 5 and 6. Iz; this form of construction the generation and discharge of ozone takes place in and from the space f between the electrodes c and the `vdielectrics a-b and preferably `the electrical component vwhich energizes the electrodes c is contained in a suitable circular housing g that serves the purpose of a support for the several convolutions of the ozone generating elements aforesaid.
The'housing g contains the usual primary and secondary coils 71, and z' respectively and suitable terminal sockets 7' and c are provided for the connection to the source of current supply as shown in Figures 5 and 6.
Figure 3 shows another form of ozone generator element wherein the electrode c (shown in broken lines) and ridge pieces d are secured as previously described to the Atwo bands or strips @"-b and then another band or strip of flexible ozone resisting insulating material arib is fastened'tol the u other; side of the ridge piece d and the Whole rolled or convolvedand secured as above defscribed.
In this form of-construction the radiation or discharge which generates ozone is between two dielectricsthat is to say the space f between the two bands or strips of iexible ozoneI resisting in sulatin,.` ir material 4a b which are supported by the ridge pieces and in such an ozone generator there is prof vided 'an annular gap or aperture for the generation of ozone of a Widthequal to the thickness of the ridgepieces and excepting for the interruptionot thelatter of a length approximately equal to the length of thev electrodes.,A ,A 1 v Figure 4 shows another modification of the construction otanjozone generator element wherein the electrode c is of a corrui :gated form contained between the dielectries that constitute the air gap It willbe obvious that the dielectric strips 'or bands maybe corrugated or ridge pieces formed thereon instead of the electrode being corrugated as shown whereby the same effect is obtained with i l a manner that the apices/. of the hollow cones or pyramids 3, 4 are burst or pierced fwhereby the active points are intensified and consequentlyA increased efiiciency obtained. The proportion or number of the hollow cones or pyramids provided on the surface ot the sheet or strip 2 must notbe less than 300 to the square inch.
-In the forms of ozone generators in which a passage for the atmosphericv or other oxygen to be ozonized is through the lflexible electrode and'along and about the points or parts of the same which are in contact with the dielectric the methods of construction are similar to those already described eX- cept that in the case of such an electrode no corrugations or ridges need be used.
The methods of construction above Adescribed may be used separately or partly in combination andthe numberof electrodes vmay be more than two.
What' I claim is:- 1. Electrical apparatus for vlgeneradzing form of electrode suitable for ozone comprising thecombination with plurality of metallicV electrodes of a plurality of dielectrics comprising bands of ,insulating material upon which said electrodes are mounted, and means for providing the necessary air gaps between said electrodes and dielectrics that are woundupon one a'nother in the form of a convolute.
2. Electrical apparatus for generating ozone comprising the combination vwith a plurality of metallic electrodes of a plurality of `dielectrics comprising bands of insulating material upon which said elec'tro s are mounted and a plurality ot distance pieces of insulating material interposed between said electrodes andv dielectrics that are wound upon one another in the form ot a convolute.
3. Electrical apparatus for -generating ozone comprising the combination with a plurality of `metalli-c corrugated electrodes of a. plurality of dielectrics comprising bands ot insulating material upon ywhich said electrodes are mounted, said electrodes and' dielectrics being wound lupon one another in the form of a convolute.
4. Electrical apparatus for generating` ozone comprising the combination with a plurality of metallic electrodes of a pluralityvof dielectrics comprising corrugated bands of insulating material upon which said electrodes are'mounted, said electrodes y and dielectrics being woundupon one another in the form of afconvolute. v
