型の屋内設置の装置では厄介で、コストが嵩む。<Problems to be solved by the invention> Therefore, in the deoxygenation reaction tower, hydrogen gas is separated and accumulated in the upper part of the tower and accumulates.Therefore, an automatic exhaust valve is attached to the top of the reaction tower to keep the pressure of the accumulated hydrogen gas constant. When it is above, exhaust to the outside. Since hydrogen gas explodes depending on the mixing ratio with oxygen (air), the hydrogen gas exhausted from the reaction tower is led to a safe place outdoors away from the device by a duct or the like, and diffused or released. It burns and releases, which is cumbersome and costly for small indoor installations.

るようになっている。<Example> In the illustrated example, 1 is a deoxygenation reaction tower, 2 is a packed bed of the catalyst resin filled in the lower half of the reaction tower, and water is supplied through a water supply pipe 3 to the inside of the deoxygenation reaction tower. It is supplied to a position slightly above the upper surface of the filling layer 2. In the middle of this water supply pipe 3, a hydrogen gas supply pipe 5 coming from a hydrogen gas source 4 such as a hydrogen generator or a hydrogen gas cylinder with a pressure adjusting mechanism is connected, and hydrogen gas is added to the water supply flowing in the water supply pipe 3. , To mix.
さて、給水管３にはエゼクター６を設け、このエゼクタ

に設けてもよい。The water supply pipe 3 is provided with an ejector 6, and the suction port 7 of this ejector is connected to the top of the reaction tower 1 by a return pipe 8 for surplus hydrogen gas. In this embodiment, the ejector 6
Is provided downstream of the connection position of the air supply pipe 5, but may be provided upstream.

９を閉じるようにしてある。Then, an automatic valve 9 is provided in the middle of the air supply pipe 5, and the reaction tower 1
A level switch 10 for detecting the water level in the tower is attached to the top of the tower, and when the excess hydrogen gas accumulates in the upper part of the tower and the water level in the tower drops to a certain level, the level switch 10 closes the automatic valve 9. There is.

水管３内に注入、混合され、脱酸素反応塔内で給水中の
溶存酸素と反応してこれを除去する。従って、反応塔の
底部の排水管11からは脱酸素水が排出する。The operation of this device is performed as follows. Water supply is supplied to the deoxygenation reaction tower 1 through the water supply pipe 3 and the ejector 6. Further, hydrogen gas is injected from the hydrogen gas source 4 into the water supply pipe 3 through the air supply pipe 5 and mixed, and reacts with dissolved oxygen in the feed water in the deoxygenation reaction tower to remove it. Therefore, the deoxidized water is discharged from the drain pipe 11 at the bottom of the reaction tower.
送気管５からの水素ガス注入量は、前述したように必要
量よりも少し過剰になっているので余剰の未溶解の水素
ガスは反応塔の上部に溜るが、給水管３の途中のエゼク
ター６を給水が通過する際に生じる負圧でエゼクターに
吸引され、給水と混合する。As described above, the amount of hydrogen gas injected from the air supply pipe 5 is slightly larger than the required amount, so excess undissolved hydrogen gas accumulates in the upper part of the reaction tower, but the ejector 6 in the middle of the water supply pipe 3 Is sucked into the ejector by the negative pressure generated when the water supply passes, and is mixed with the water supply.
反応塔の上部に溜る余剰水素ガスの量が、エゼクターの
常時吸引量を上回り、これによって塔内の水面を押下
げ、水位が一定のレベルまで低下するとレベルスイッチ
10がこれを検出し、送気管５の途中の自動弁９を閉じる
と、水素ガス源４から水素ガスの供給は停止する。従っ
て、その後はエゼクター６の吸引により反応塔内上部に
溜る水素ガスのみが給水に添加される。The amount of excess hydrogen gas that accumulates in the upper part of the reaction tower exceeds the amount of the ejector that is constantly sucked, which pushes down the water surface in the tower, and when the water level drops to a certain level, the level switch
When 10 detects this and closes the automatic valve 9 in the middle of the air supply pipe 5, the supply of hydrogen gas from the hydrogen gas source 4 is stopped. Therefore, after that, only the hydrogen gas accumulated in the upper part of the reaction tower is added to the feed water by the suction of the ejector 6.
こうして反応塔内上部の水素ガスの量が減少し、水位が
次第に上昇して所定のレベルに達するとレベルスイッチ
10は自動弁９を開にし、水素ガス源４から水素ガスを供
給させる。In this way, the amount of hydrogen gas in the upper part of the reaction tower decreases, and when the water level gradually rises and reaches a predetermined level, the level switch
10 opens the automatic valve 9 to supply hydrogen gas from the hydrogen gas source 4.
以上の動作を繰返す。The above operation is repeated.
尚、12はエゼクター６で吸引される水素ガス中に含まれ
た凝縮水排出用のドレンである。Reference numeral 12 is a drain for discharging condensed water contained in the hydrogen gas sucked by the ejector 6.

設備が不要になるためコストの低下が図れる。<Effect of device> As is clear from the above, in the present invention, hydrogen gas is supplied to the deoxygenation reaction tower in a slightly excessive amount, and the hydrogen gas accumulated in the tower is supplied from the air supply pipe by the excess gas return pipe and the ejector. Even when injecting new hydrogen gas into the pipe, it circulates through the water supply pipe, and when the water level in the tower drops to a certain level, the level switch detects this and closes the automatic valve of the air supply pipe to add new hydrogen gas. The circulation of the surplus gas is continued even when the injection of the gas is stopped. Thereby, when the injection of hydrogen gas is simply stopped by the level control of the level switch, the untreated dissolved oxygen in the treated water increases, but even when the injection of new hydrogen gas is stopped as described above, in the present application, Since the excess hydrogen gas accumulated in the upper part of the deoxygenation reaction tower circulates, the dissolved oxygen in the water does not increase, and the deoxygenation treatment efficiency improves. Then, the hydrogen gas separated in the upper part of the deoxygenation reaction tower is sucked by the ejector and circulated to be used for the deoxygenation reaction, so that the hydrogen gas can be effectively and labor-savingly used, and the risk due to release is eliminated. it can. In addition, since equipment for leading to a safe place outdoors for diffusion and emission or combustion and emission is not required, the cost can be reduced.
