In this case, if air is used as a raw material, the ozone concentration produced will be low (below 1, VO 1%) and unnecessary nitrogen oxides will be produced, and if oxygen is used, the ozone concentration will be high, but it is an expensive oxygen source. It becomes necessary.

いた。Problems to be Solved by the Invention As described above, the conventional water electrolysis type ozone generator produces ozone containing oxygen, but on the other hand, unnecessary and dangerous hydrogen is produced as a by-product. If ozone is to be used effectively for deodorization, decolorization, sterilization, etc., it is necessary to appropriately treat the hydrogen produced as a by-product. Conventionally, methods for doing so include the combustion method, which simply involves burning, or has the following drawbacks.

かも使用中は常時燃えているから金側な発熱源となり、
周囲の環境も悪くなるし、付近に引火性の物質が存在す
るような場所での運転は不可能であった。That is, after stopping the water electrolysis type ozone generator, it is necessary to ignite the hydrogen scum each time the operation is restarted, and igniting hydrogen, which is an explosive gas, is an extremely dangerous operation. Moreover, it is constantly burning during use, so it becomes a major source of heat generation.
The surrounding environment would also deteriorate, and it was impossible to operate in areas where flammable substances were present nearby.

っていた。Another method for treating hydrogen is a catalytic oxidation method in which oxidation is performed without exposing it to external flame. This method uses an oxidation catalyst in which platinum, palladium, etc. are supported on a carrier such as activated alumina, and oxidizes at low temperatures in the presence of oxygen, and is suitable for oxidizing combustible gases at relatively low concentrations. . Therefore, the 1 produced by the water electrolysis method described above
To process 0.00% hydrogen, it is necessary to mix in an appropriate amount of oxygen or air. In this case, if the hydrogen concentration in the mixed sludge increases, the catalyst temperature will become too hot and the life will be shortened, so the mixing ratio of hydrogen and oxygen or air must be kept at an optimal value, and its control is Not only is it difficult, but it also requires a large amount of catalyst, which has the disadvantage of increasing the size of the equipment.

理するものである。Means for Solving the Problems In the present invention, in order to provide an ozone generator that can safely and reliably treat hydrogen by-produced during water electrolysis, a method different from conventional combustion methods and catalytic oxidation methods, namely , employing electrochemical means. The outline of this method is to form electrodes called scum diffusion electrodes on both surfaces of an ion exchange resin membrane.
Hydrogen by-produced by water electrolysis is supplied to one side of the membrane, air is supplied to the other side, and the gas diffusion electrodes on both sides of the membrane are connected through a short circuit or an appropriate resistance, and the by-product hydrogen is electrochemically It can be safely disposed of by oxidizing it and converting it into water.

することになる。An example of a method for forming a gas diffusion electrode is to mix and support catalyst metal powder such as platinum or palladium on carphone powder, and add aqueous suspension of polytetrafluoroethylene, so-called Teflon dispersion, etc. to this mixed powder. An adhesive is added to form a sticky paste or liquid mixture, and this is bonded into a membrane by coating, spraying, heat pressing, etc. on the surface of the ion exchange resin membrane. Since the solvent in the Teflon dispersion evaporates during post-treatments such as heating and evaporation, non-volatile catalyst metals, carbon powder, Teflon fine particles, etc. remain as a porous mixture on the surface of the ion exchange resin membrane. It functions as an effective dregs diffusion electrode.

によって酸化され、水を生成する。In this way, a pair of sludge diffusion electrodes formed on both surfaces of the ion exchange resin membrane are connected externally via a short circuit or an appropriate resistance to form an electrochemical cell similar to a so-called fuel cell. . When by-product hydrogen is supplied to one side of the gas diffusion electrode, hydrogen is oxidized to hydrogen ions at the interface between the gas diffusion electrode and the ion exchange resin membrane by the following reaction 2H2−4H+ +4e. When oxygen or air is supplied to the other side of the scum diffusion electrode, the hydrogen ions easily move inside the ion exchange resin membrane that functions as an isoelectrolyte, resulting in the following reaction 4H"102 +4 e- → Oxidized by 2H20 to produce water.

る。As described above, the hydrogen treatment cell is configured such that the hydrogen supply side is the negative electrode and the oxygen supply side is the positive electrode, and a short circuit current corresponding to the electrochemical equivalent of the treated hydrogen flows from the positive electrode to the negative electrode. On the other hand, the size of the hydrogen treatment cell is the same as or slightly larger than the ozone generation cell, which contributes to miniaturization of the device. As is clear from the above explanation, since hydrogen is automatically oxidized, no maintenance is required.

Store inside. The hydrogen port 22 on the negative electrode side is connected to the hydrogen outlet 13 of the ozone generating cell 1, and hydrogen is supplied thereto. On the other hand, when air is supplied through the air supply port 23 on the positive electrode side, hydrogen is consumed at the negative electrode, and some oxygen in the air is consumed at the positive electrode, producing water, as shown in the electrochemical reaction equation described above. This water along with excess air comes out 4JF1]2

(90 Vo1%) was obtained, and a short circuit current of 10 A also flowed between the positive and negative electrode plates 1, 9, and 20 of hydrogen treatment cell 2, confirming that all by-product hydrogen scum was completely treated. .
発明の効果
本発明の水電解式オゾン発生機から発生するオゾンは従
来の放電式に比べて高純度で、かつ極めて濃度が高い。Effects of the Invention Ozone generated from the water electrolysis type ozone generator of the present invention has higher purity and extremely high concentration than the conventional discharge type ozone generator.
そのため、オゾン発生機か大幅に小形・軽量化され、装
置の製造コストも安くなる。As a result, the ozone generator can be made much smaller and lighter, and the manufacturing cost of the device will also be lower.

つ確実に処理することもできる。Furthermore, in the ozone generator of the present invention, by-produced hydrogen is not released to the outside at all, and is treated electrochemically within the system immediately after generation, so it is safe even in places where there is a fire nearby. can be operated. In addition, since the amount of hydrogen processed can be easily determined from the short circuit current value,
It is also possible to process hydrogen completely and reliably while understanding the performance and sealing of the hydrogen processing cell.
