この発明は酸素濃縮装置とオゾン発生器を組み合わせた
オゾン発生装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of an ozone generator that combines an oxygen concentrator and an ozone generator.
オゾンを放電を用いて製造する場合、原料ガスを乾燥空
気から酸素へ替えると同一のオゾンを生成するのに必要
な放電電力が約２分の１に低減できることは静電気学会
誌７巻３号１５０″ｆ′Ｘを始め数多くの報告がある。When producing ozone using electrical discharge, if the raw material gas is changed from dry air to oxygen, the electrical discharge power required to produce the same ozone can be reduced to about half. There are many reports including ``f'X.

る。In this case, the power required to generate ozone corresponds to one degree of oxygen, and it is also shown that the discharge power can be reduced even if the oxygen is not pure. Additionally, a device that uses air as the raw material gas and uses adsorption to increase oxygen concentration is described in "Zeolite Molecular Sieve" published by John Wiley & Sons, p. 710 (1974) and in Japanese Patent Application Laid-Open No. 60-246205. There is something shown.

を製造する。The raw air is pressurized to atmospheric pressure or higher by the blower (2) and sent to the adsorption towers (1-a) and (1-b). In the figure, valves (3), (6), and (7) are open, and valves (4) and (5) are open.
, (8) are in a closed state, the adsorption tower (1-a) performs an adsorption operation, and the adsorption tower (1-b) performs a regeneration movement. The raw air enters the adsorption tower (t-a), nitrogen in the components is selectively adsorbed, and the gas with increased oxygen concentration is discharged from the valve (7). The valves (4), (5), (
8) is opened, valves (3), (6), and (7) are switched to the closed state, and the adsorption tower (1-b) is in adsorption operation, and the adsorption tower (1-
a) performs a playback operation. The regeneration operation is performed by discharging the nitrogen adsorbed in the previous adsorption operation to the outside of the adsorption tower using a vacuum suction pump (9). Adsorption is achieved by switching the valve as described above. The thus generated gas with high oxygen concentration is supplied to the ozone generator (9) to produce ozone with a small amount of electric power.

題が発生する。In order for this device to be economically viable, it is required that the power consumption be the same or lower than that of an ozone generator that uses air as a raw material. For this purpose, it is necessary to reduce the power consumption of the vacuum suction pump, which consumes a large amount of power. In other words, although the oxygen concentration in the produced gas decreases somewhat,
By lengthening the switching cycle of the adsorption tower or increasing the amount of air processed per unit weight of adsorbent, the power consumption of the vacuum suction pump per unit amount of oxygen-enriched gas produced can be reduced. On the other hand, the power consumption of an ozone generator corresponds to the oxygen concentration, and the power consumption increases as the oxygen concentration decreases. Considering the total amount of electricity required to generate a unit weight of ozone based on this relationship, it is found that if the operation of the first adsorption tower group is switched when the exhaust oxygen concentration reaches a range of 40% to 93%, It is economical and provides minimum power consumption under the conditions of 60% or more and 85% or less. However, under these conditions, as shown in FIG. 4, the oxygen concentration periodically fluctuates greatly, and the ozone concentration produced also fluctuates accordingly, leading to problems such as being unable to be applied to some applications or being subject to significant restrictions.

た吸着塔を新たに設け↑たもので１ある。The ozone generator according to the present invention is one in which an adsorption tower filled with an adsorbent that adsorbs nitrogen or oxygen is newly installed between the adsorption tower and the ozone generator.

返して酸素濃度変動の緩和を行なう。In this invention, even if the newly installed adsorption tower has a small capacity, it can spontaneously repeat the operation of adsorbing and desorbing excess or insufficient oxygen or nitrogen in response to periodic oxygen concentration fluctuations, thereby alleviating the oxygen concentration fluctuations. Do this.

The operations of the component devices having the same symbols as those in the figure are the same as those of the conventional device, and the explanation thereof will be omitted. Adsorption tower group (1-a), (1
-b), a gas with periodic oxygen concentration fluctuations is supplied to the concentration buffer α. This is filled with an adsorbent capable of adsorbing nitrogen or oxygen, and here, zeolite having a pore diameter of 5 angstroms that selectively adsorbs nitrogen will be used as an example. When a gas with a nitrogen concentration higher than the average value is supplied, excess nitrogen is adsorbed on the zeolite and is discharged from the concentration buffer α◇ as a gas with an oxygen concentration somewhat lower than the supplied oxygen concentration. On the other hand, when a gas with a nitrogen concentration lower than the average value is supplied, the nitrogen accumulated in the adsorbent is released into the gas and is released from the concentration buffer α as a gas with an oxygen concentration somewhat lower than the supplied oxygen concentration. be discharged. In this way, fluctuations in nitrogen concentration are alleviated and gas with a constant oxygen concentration is supplied to the ozone generator. Figure 5 shows an example of alleviating fluctuations in oxygen concentration at the inlet and outlet of a concentration buffer.The retention time in the concentration buffer is 5 seconds, and the adsorbent temperature is 0°.
These are the results under the condition that the C1 oxygen concentration fluctuation period is 1 minute.
なお、酸素濃度変動の緩和効果に対する吸着剤温度の影
響は大きく、第６図に示すように温度を下げる程顕著に
濃度変動の緩和が行なえる。It should be noted that the influence of the adsorbent temperature on the effect of alleviating oxygen concentration fluctuations is large, and as shown in FIG. 6, the lower the temperature, the more markedly the concentration fluctuations can be alleviated.
上記の例では窒素を選択的に吸着する吸着剤を挙げたが
、酸素を選択的に吸着する吸着剤を第二の吸着塔に充填
した場合も同等の効果が得られろのはいうまでもない。Although the above example uses an adsorbent that selectively adsorbs nitrogen, it goes without saying that the same effect can be obtained if the second adsorption tower is filled with an adsorbent that selectively adsorbs oxygen. do not have.
