Description

Verfahren zur Erzeugung von Ozon mittels Entladungen, vorzugsweise für Hochfrequenzbetrieb Es ist bekannt, daß man die einem Ozonisierungsapparat zugeführte Luft bzw. Sauerstoff vor dem Eintritt in den Apparat trocknen muß. Bei der Anwendung von Hochfrequenzwechselstrom für Ozonerzeugung war es bisher nur möglich, verhältnis-1 liä ' ßi, g -eringe Z, Ozonkonzentrationen zu erreichen, weil sich häufig Sekundärprodukte dabei bildeten, insbesondere Stickoxyde, die zersetzend auf das Ozon einwirkten.Process for generating ozone by means of discharges, preferably for high-frequency operation It is known that the air or oxygen supplied to an ozonization apparatus must be dried before it enters the apparatus. When using high-frequency alternating current for ozone generation, it was previously only possible to achieve ratio-1 liä ' ßi, g -eringe Z, ozone concentrations because secondary products were often formed, in particular nitrogen oxides, which had a decomposing effect on the ozone.

Die Erfindung bezweckt, insbesondere bei Anwendung von Hochfrequenzwechselstrom den Betrieb von Ozonapparaten erheblich wirtschaftlicher zu gestalten. Dies wird gemäß der Erfindung dadurch erreicht, daß das dein Ozonisierungsapparat zugeführte Gas, insbesondere Luft, durch Kieselsäuregel getrocknet wird. Hierdurch wird gegenüber anderen Trocknungsmitteln die Ozonkonzentration und die Ausbeute überraschend hoch gesteigert.The invention aims, especially when using high-frequency alternating current to make the operation of ozone machines much more economical. this will achieved according to the invention in that the ozonizing apparatus supplied to the Gas, especially air, is dried by silica gel. This is opposite other drying agents the ozone concentration and the yield surprisingly high increased.

Ausführungsbeispiel Eine große Ozonröhre, die finit io cbm Luft pro Stunde beschickt wurde, lieferte unter Anwendung eines Wechselstromes von t o 000 Per. und einer Spannung von 7 500 Volt eine Ozonkonzentration von ungefähr 3 g pro Kubikmeter, wenn man die zugeführte Luft mittels Chlorcalciums trocknete. Die Ausbeute pro Stunde betrug mithin 30 g Ozon. Wenn man unter den gleichen Betriebsverhältnissen, die oben angegeben sind, die gleiche Röhre verwendet, aber als Trocknungsmittel Kieselsäuregel benutzt. so steigt überraschenderweise die Ozonkonzentration auf ungefähr io g pro Kubikmeter, und die Ausbeute pro Stunde beträgt in diesem Falle ioo g. EXEMPLARY EMBODIMENT A large ozone tube, which was charged finitely 10 cbm of air per hour, produced an ozone concentration of approximately 3 g per cubic meter using an alternating current of to 000 people and a voltage of 7,500 volts if the air supplied was dried with calcium chloride. The hourly yield was therefore 30 g of ozone. If the same tube is used under the same operating conditions as given above, but silica gel is used as the desiccant. so, surprisingly, the ozone concentration rises to about 10 g per cubic meter, and the yield per hour in this case is 100 g.

Aus dem vorstehenden Ausführungsbeispiel ist die außerordentlich große Überlegenheit des neuen Verfahrens deutlich erkennbar.From the above embodiment, the is extremely large The superiority of the new process is clearly evident.

Kieselsäuregel ist als Trocknungsmittel aber nicht nur dem Chlorcalcium überlegen, was ja auf Grund der bekannten trocknenden Eigenschaften dieser beiden Mittel zu erwarten war, sondern auch die Ausbeute an Ozon wird gesteigert, wenn man an Stelle von Phosphorpentoxyd Kieselsäuregel zum Trocknen der zu ozonisierenden Luft benutzt. Durch eine Ozonröhre, die mit ioooo Iiz und einer Spannung von 7 zoo Volt betrieben wurde, wurde die Luft mit Hilfe eines Kompressors geschickt. Die Geschwindigkeit der Luft betrug 6 cbm pro Stunde, und die aufgenommene Leistung war i,i kW. Wurde die Luft, bevor sie in die Ozonröhre eintrat, mit Hilfe von Chlorcalcium und Phosphorpentoxvd getrocknet, so war die Luft vollkommen frei von Wasserdampf, und die Ausbeute an Ozon betrug 7,.4 g pro Kubikmeter. Wurde dagegen an Stelle des Phosphorpentoxydes zum Trocknen Kieselsäuregel benutzt, so enthielt die Luft noch ganz geringe Mengen Wasserdampf, die sich mit Hilfe von Phosphorpentoxyd nachweisen ließen.- Trotzdem stieg die Ausbeute an Ozon auf 9,2 g pro Kubikmeter. Die Steigerung der Ausbeute ist wahrscheinlich auf das Fehlen von Öldämpfen in der Luft bei Benutzung von Kieselsäuregel zurückzuführen.Silica gel is used as a drying agent but not only the calcium chloride consider what yes due to the known drying properties of these two Means was to be expected, but the ozone yield will be increased, though instead of phosphorus pentoxide, silica gel is used to dry the ozonized Uses air. Through an ozone tube with ioooo Iiz and a voltage of 7 zoo Volt was operated, the air was sent with the help of a compressor. the The air speed was 6 cbm per hour and the power consumed was i, i kW. Before entering the ozone tube, the air was made with the help of calcium chloride and phosphorus pentoxide dried, so the air was completely free of water vapor, and the ozone yield was 7.4 grams per cubic meter. Instead of the Phosphorus pentoxide for Used drying silica gel so contained the air still has very small amounts of water vapor, which is produced with the help of phosphorus pentoxide - Nevertheless, the yield of ozone rose to 9.2 g per cubic meter. The increase in yield is likely due to the lack of oil vapors in the Air when using silica gel.
