Anordning for fremstilling av ozon. Device for producing ozone.
Foreliggende oppfinnelse angår en anordning for fremstilling av ozon under an-vendelse av en ozongenerator som inneholder to elektroder som er koblet til en strømkilde og mellom hvilke det er ut-formet en forholdsvis trang gjennomstrøm-ningskanal som tjener som utladningsrom.

Until now, however, it has not been possible in practical operation at reasonable costs to lower the temperature so low that a particularly significant increase in the ozone concentration in the gas mixture leaving the generator has been achieved.
Foreliggende oppfinnelse som bygger Present invention that builds
på de prinsipper som er angitt ovenfor, on the principles set out above,
går ut på å gjøre det mulig å foreta en effektiv og økonomisk kjøling av ozongeneratoren, samtidig som det utvinnes en gass-blanding med høy ozon-konsen-trasjon. involves making it possible to carry out efficient and economical cooling of the ozone generator, while at the same time extracting a gas mixture with a high ozone concentration.
Ved at den kjøleluftmengde som ikke suges inn i ozongeneratoren, hele tiden sirkulerer går det ikke tapt noen særlig kjøleeffekt, og kjøleluften kan derfor gis så stort volum at den varme som avgis av elektrodene, bevirker en ganske rimelig temperaturforhøyelse. Generatoren hol- As the amount of cooling air that is not sucked into the ozone generator constantly circulates, no particular cooling effect is lost, and the cooling air can therefore be given such a large volume that the heat given off by the electrodes causes a fairly reasonable increase in temperature. The generator hol-

sjon. Som eksempel kan nevnes at den luft som kommer fra kjøleanlegget, kan ha en temperatur mellom 4-10 og -4-15°C, og av denne luft kan eksempelvis 2—5 pst. tas ut gjennom generatoren mens resten av kjøle-luftmengden får sirkulere. Temperaturen i generatorens reaksjonsrom kan under tion. As an example, it can be mentioned that the air coming from the cooling system can have a temperature between 4-10 and -4-15°C, and of this air, for example, 2-5 per cent can be taken out through the generator, while the rest of the cooling air quantity gets circulate. The temperature in the generator's reaction room can drop below
slike forhold ligge på ca. 0°C, i hvertfall under +10°C. Ved tidligere fremstilling av ozon har det som regel ikke vært mulig å unngå en temperatur på 20—30°C i reak-sjonsrommet, slik at ozonutbyttet ble til-svarende dårligere. such conditions lie at approx. 0°C, in any case below +10°C. In previous production of ozone, it has usually not been possible to avoid a temperature of 20-30°C in the reaction room, so that the ozone yield was correspondingly worse.
Oppfinnelsen omfatter således en anordning for fremstilling av ozon og anordningen består av en eller flere ozongenera-torer som hver for seg inneholder to elektroder som er koblet til en strømkilde og mellom hvilke det finnes en forholdsvis trang gjennomstrømningskanal som tjener som utladningsrom og hvis ene ende er åpen mens den annen ende kan forbindes med et forbrukssted gjennom en ledning. Det særegne ved oppfinnelsen består i at ozongeneratorene og et kjølebatteri er byg-get inn i to adskilte, fortrinnsvis varmeisolerte kammere som står i forbindelse med hverandre gjennom to kanaler som er anordnet ved hver sin ende av kjølebatte-riet, at en vifte er innrettet til å bringe en luftstrøm til å sirkulere gjennom de to kammere, og at kjølebatterikammeret dessuten står i forbindelse med den ytre luft gjennom en åpning som befinner seg i avstand fra de nevnte kanaler. The invention thus includes a device for the production of ozone and the device consists of one or more ozone generators that each contain two electrodes that are connected to a current source and between which there is a relatively narrow flow channel that serves as a discharge chamber and one end of which is open while the other end can be connected to a point of consumption through a wire. The peculiarity of the invention is that the ozone generators and a cooling battery are built into two separate, preferably heat-insulated chambers that are connected to each other through two channels arranged at each end of the cooling battery, that a fan is arranged to to cause a current of air to circulate through the two chambers, and that the cooling battery chamber is also in communication with the external air through an opening located at a distance from the said channels.
På vedføyete tegning viser fig. 1 skje-matisk en utførelsesform for anordningen i henhold til oppfinnelsen i loddrett snitt, mens fig. 2 og 3 viser loddrette snitt gjennom øvre henhv. nedre ende av en ozongenerator av rørtypen. The attached drawing shows fig. 1 schematically shows an embodiment of the device according to the invention in a vertical section, while fig. 2 and 3 show vertical sections through the upper or lower end of a tube-type ozone generator.
I fig. 1 betegner 4 et hus som ved hjelp av en loddrett og en vannrett skillevegg 5 henhv. 6 er delt i tre kammere 7, 8, 9 hvorav det ene 7 omslutter et antall ozon-generatorer 10, i den viste utførelse 2 styk-ker, samt en høyspenningstransformator 11. Kammeret 8 inneholder en kjølekom-pressor 12 som gjennom rørledninger 13, 14 er koblet til et kjølebatteri 15 som er innbygget i kammeret 9. Kamrene 7 og 9 er fortrinnsvis varmeisolerte, og kammeret 9 har øverst en åpning 16 hvorigjen-nom det står i forbindelse med den ytre luft. In fig. 1 denotes 4 a house which by means of a vertical and a horizontal dividing wall 5 respectively. 6 is divided into three chambers 7, 8, 9, one of which 7 encloses a number of ozone generators 10, in the shown embodiment 2 pieces, as well as a high-voltage transformer 11. The chamber 8 contains a cooling compressor 12 which through pipelines 13, 14 is connected to a cooling battery 15 which is built into the chamber 9. The chambers 7 and 9 are preferably thermally insulated, and the chamber 9 has an opening 16 at the top through which it is in contact with the outside air.
Kjølebatteriet 15 har en loddrett gjen-nomstrømningskanal 17 hvis nedre ende er åpen. Fra den øvre ende av kanalen 17 går det ut en kanal 18 som munner ut i den øvre del av generatorkammeret 7. En vifte 19 som er anbragt i kanalen 18, suger luft oppover gjennom kjølekanalen og fører den kjølte luft inn i kammeret 7. Fra den nedre del av generatorkammeret 7 går det ut en loddrett kanal 20 som munner ut i kjølebatterikammeret 9 like ved innløps-enden for kanalen 17. The cooling battery 15 has a vertical through-flow channel 17 whose lower end is open. From the upper end of the channel 17, a channel 18 exits which opens into the upper part of the generator chamber 7. A fan 19, which is placed in the channel 18, sucks air upwards through the cooling channel and leads the cooled air into the chamber 7. From in the lower part of the generator chamber 7, a vertical channel 20 exits which opens into the cooling battery chamber 9 close to the inlet end of the channel 17.
Ozongeneratorene 10, som fortrinnsvis er av rørtypen, har sine ytre og indre elektroder koblet til høyspenningstrans-formatoren 11 gjennom ledninger 21 henhv. 22. Den ytre elektrode kan bestå av et metallbelegg 23 på et glassrør 24 som tjener som dielektrikum, mens den indre elektrode kan utgjøres av et aluminiumrør 25, fig. 2 og 3. De to ender av det indre rør er lukket ved hjelp av lokk 26 som holdes fast ved hjelp av muttere 27 som er skrudd inn på endene av en forbindelsesstang 28 som går aksialt gjennom røret og er ført ut gjennom sentrumhull i lokkene. En utvendig gjenget hylse 29 er tredd på hver av endene av ytterrøret 24 og en innven-dig gjenget koblingshylse 30 er under inn-legg av en tetningsring 31 som griper inn mot glassrøret 24 skrudd på hylsen 29. Det indre rør 25 er fastholdt koaksialt i det ytre rør ved at de to endelokk 26 har utvendig gjengete kantflenser 32 som er skrudd inn i koblingshylsene 30. På denne måten holdes hele ozongeneratoren sam-men ved hjelp av enkle midler, slik at den ved behov lett kan demonteres for eventuelt utskifting av deler. For at luften skal kunne strømme gjennom det ringformete mellomrom 33 mellom det ytre rør 24 og det indre rør 25 er kantflensene 32 på lokkene forsynt med et stort antall perforeringer eller utsparinger 34. Eventuelt kan flen-sene være utført som en tanning rundt lokkene. Koblingshylsene må naturligvis være av isolasjonsmaterial, hensiktsmessig plast. The ozone generators 10, which are preferably of the tube type, have their outer and inner electrodes connected to the high-voltage transformer 11 through lines 21 or 22. The outer electrode can consist of a metal coating 23 on a glass tube 24 which serves as a dielectric, while the inner electrode can consist of an aluminum tube 25, fig. 2 and 3. The two ends of the inner tube are closed by means of lids 26 which are held in place by means of nuts 27 which are screwed onto the ends of a connecting rod 28 which passes axially through the tube and is led out through central holes in the lids. An externally threaded sleeve 29 is threaded onto each of the ends of the outer tube 24 and an internally threaded coupling sleeve 30 is fitted with a sealing ring 31 which engages against the glass tube 24 screwed onto the sleeve 29. The inner tube 25 is held coaxially in the outer tube in that the two end caps 26 have externally threaded edge flanges 32 which are screwed into the coupling sleeves 30. In this way, the entire ozone generator is held together by means of simple means, so that it can be easily dismantled if necessary for possible replacement of parts . In order for the air to be able to flow through the annular space 33 between the outer tube 24 and the inner tube 25, the edge flanges 32 on the lids are provided with a large number of perforations or recesses 34. Optionally, the flanges can be designed as a tan around the lids. The connection sleeves must of course be made of insulating material, suitable plastic.
Koblingshylsene 30 ved de nedre ender av generatorene er festet til knekter 35, fig. 3, som rager ut fra den ene vegg i kammeret 7. De øvre koblingshylser 30 er tettende forbundet med en felles samle-kasse 36 hvorfra en rørledning 37 går til sugesiden på en pumpe som ikke er vist og som er innrettet til å føre ozongass-blandingen videre til et forbrukssted. The coupling sleeves 30 at the lower ends of the generators are attached to jacks 35, fig. 3, which protrudes from one wall of the chamber 7. The upper coupling sleeves 30 are sealingly connected to a common collection box 36 from which a pipeline 37 goes to the suction side of a pump which is not shown and which is designed to carry ozone gas the mixture further to a point of consumption.
Som det i det vesentlige allerede frem-går av det som er sagt ovenfor, virker denne anordning slik at viften 19 bringer luft til å passere gjennom kjølebatteriet inn i den øvre del av kammeret 7 hvor luften som eksempelvis er nedkjølet til -=-10 eller + 15°C, synker nedover under spyling rundt elektroderørene 23, 24. En mindre brøkdel av luften suges inn i utladningsrommene 33 mellom elektrodene 23, 25 for, etter ozondannelse å strømme ut gjennom ledningen 37, mens den største del av luften føres tilbake til kjølebatterikammeret 9 gjennom kanalen 20. Gjennom åpningen 16 suges frisk luft inn i en mengde som As is essentially already clear from what has been said above, this device works so that the fan 19 brings air to pass through the cooling coil into the upper part of the chamber 7 where the air, which has been cooled to -=-10 or + 15°C, sinks downwards during flushing around the electrode tubes 23, 24. A smaller fraction of the air is sucked into the discharge spaces 33 between the electrodes 23, 25 in order, after ozone formation, to flow out through the line 37, while the largest part of the air is led back to the cooling battery chamber 9 through the channel 20. Through the opening 16, fresh air is sucked in in an amount that
tilsvarer den ozongassblanding som føres corresponds to the ozone gas mixture that is carried
bort gjennom ledningen 37. away through the wire 37.
Som nevnt er anlegget hensiktsmessig As mentioned, the facility is appropriate
dimensjonert slik at høyst ca. 5 pst. av den dimensioned so that at most approx. 5 percent of it

Samtidig blir energiforbruket lavt 19 is taken out through the ozone generators. The cold air that circulates in large excess also causes an effective cooling of the electrodes with the resulting large ozone formation. At the same time, energy consumption is low
