A valve 14 is electrically connected to the temperature sensor 1.
When the detected temperature of the switch 3 reaches the reaction temperature of the catalyst in the reactor 1, the heating element 3 is turned off, the blower B starts operating, and the valve 14 of the switch 6 is switched to the reactor 1 side as shown in FIG. Switch.

の反応温度に達するとポンプPが作動して廃液槽12か
ら反応器1へ廃液が供給される。A pump P is electrically connected to this temperature sensor 15, and when the temperature detected by the temperature sensor 15 reaches the reaction temperature of the catalyst in the reactor 1, the pump P is activated to cause a reaction to occur from the waste liquid tank 12. Waste liquid is supplied to vessel 1.
なお、反応器1内があまり高温になりすぎると触媒の劣
化が早くなるためポンプPが停止して廃液が供給されな
いようにしである。Note that if the temperature inside the reactor 1 becomes too high, the catalyst will deteriorate quickly, so the pump P is stopped to prevent the supply of waste liquid.
次に、図示した装置を使用するには以下のようにする。To use the illustrated apparatus, proceed as follows.
まず、加熱体3をオンにして反応器1内を加熱する。First, the heating element 3 is turned on to heat the inside of the reactor 1.
加熱された熱風は、加熱体3と同時にオンしたファン1
1により反応器1の出口5に送出される。The heated hot air is heated by the fan 1 which is turned on at the same time as the heating element 3.
1 to the outlet 5 of the reactor 1.
このときブロアーB、ポンプPはオフとなっており、切
替器6の弁14は第1図のように切替器6の出口16を
閉じている。At this time, the blower B and the pump P are off, and the valve 14 of the switch 6 closes the outlet 16 of the switch 6 as shown in FIG.
従って反応器1から排出された排気は導出路4を通って
反応器1内に戻る。Therefore, the exhaust gas discharged from the reactor 1 returns into the reactor 1 through the outlet passage 4.
この循環がしばらく継続すると反応器1内の温度が上昇
し、入口側温度検知器13に検知される温度が触媒2の
反応温度に達する。When this circulation continues for a while, the temperature inside the reactor 1 rises, and the temperature detected by the inlet side temperature sensor 13 reaches the reaction temperature of the catalyst 2.
すると、ブロアーBがオンして導入路7内に外部の空気
が導入されると同時に切替器6の弁14が第1図の状態
(切替器6の出口が閉じられている)から第2図の状態
(切替器6の反応器側出口が閉じられている)に切替り
、更に加熱器3がオフとなる。Then, the blower B is turned on and external air is introduced into the introduction path 7, and at the same time the valve 14 of the switching device 6 changes from the state shown in FIG. 1 (the outlet of the switching device 6 is closed) to the state shown in FIG. (the reactor side outlet of the switch 6 is closed), and the heater 3 is further turned off.
このとき出口側温度検知器15の検知温度も触媒の反応
温度になるためポンプPもオンとなり廃液が反応器に供
給される。At this time, the temperature detected by the outlet side temperature sensor 15 also becomes the reaction temperature of the catalyst, so the pump P is also turned on and the waste liquid is supplied to the reactor.
この結果供給された廃液は触媒により化学分解(燃焼)
される。The resulting waste liquid is chemically decomposed (combusted) by a catalyst.
be done.
燃焼が開始されると反応器1内の温度はそれ以後触媒の
反応温度以上になるため、加熱体3がオフになって加熱
が中止されても燃焼が継続される。Once the combustion starts, the temperature inside the reactor 1 becomes equal to or higher than the reaction temperature of the catalyst, so even if the heating element 3 is turned off and heating is stopped, the combustion continues.
またこの状態では、反応器1から排出される排気の温度
も常時触媒の反応温度以上になる。In addition, in this state, the temperature of the exhaust gas discharged from the reactor 1 is always higher than the reaction temperature of the catalyst.
従って、導入路7に導入される空気はその排気により加
熱され、反応器1に入る時点では触媒の反応温度以上に
なる。Therefore, the air introduced into the introduction path 7 is heated by the exhaust gas, and reaches a temperature higher than the reaction temperature of the catalyst when it enters the reactor 1.
逆に排気は導入路7内の空気に熱交換された分だけ冷却
され、切替器6の出口から排出されるときには次段の第
二次反応装置へ供給するのに適当な低温になる。Conversely, the exhaust gas is cooled by the amount of heat exchanged with the air in the introduction path 7, and when it is discharged from the outlet of the switching device 6, it has a low temperature suitable for being supplied to the next stage of the second reaction device.
本考案は叙上のようにしてなるため以下のような各種の
効果を有する。Since the present invention is constructed as described above, it has the following various effects.
■ 切替器6を設けであるため、反応器1から排出され
る排気を反応器1に循環させることができ、そのため、
反応器1内の温度を効率良く触媒の反応温度まで高める
ことができる。■ Since the switch 6 is provided, the exhaust gas discharged from the reactor 1 can be circulated to the reactor 1, and therefore,
The temperature inside the reactor 1 can be efficiently raised to the reaction temperature of the catalyst.
■ 導出路4と導入路7とを二重にしであるため導出路
4を通る熱い排気により導入路7を通る空気を加熱する
ことができ、従って反応器1に送られる空気は自然に触
媒の反応に適した温度となり、逆に排気は熱を奪われて
低温になるため外部に送出しても火災の原因になる慮れ
かない。■ Since the outlet passage 4 and the introduction passage 7 are doubled, the hot exhaust gas passing through the outlet passage 4 can heat the air passing through the introduction passage 7, and therefore the air sent to the reactor 1 is naturally heated by the catalyst. The temperature is suitable for the reaction, and conversely, the exhaust gas is deprived of heat and becomes low temperature, so even if it is sent outside, there is no way it could cause a fire.
なお、導入路7と導出路4とを蛇腹状にすれば、熱交換
効率が一層向上する。Note that if the inlet passage 7 and the outlet passage 4 are shaped like bellows, the heat exchange efficiency will be further improved.
■ 反応器1に送られる空気が排気により加熱されて触
媒の反応温度になって反応器1に入るため、反応器1内
を加熱体3により加熱しなくとも触媒が十分に反応する
。(2) Since the air sent to the reactor 1 is heated by the exhaust gas and reaches the reaction temperature of the catalyst before entering the reactor 1, the catalyst reacts sufficiently without heating the inside of the reactor 1 with the heating element 3.
従って、加熱体3は始動時にのみオンさせればよいため
消費電力が少くて済み、極めて経済的であると共に省エ
ネルギーに役立つ。Therefore, since the heating element 3 only needs to be turned on at the time of startup, power consumption is low, which is extremely economical and helps save energy.
■ 導入路7と排出路4とを二重にしであるため装置全
体を小型化できる。(2) Since the introduction path 7 and the discharge path 4 are made double, the entire device can be made smaller.
■ 図示したように、入口側温度検知器13、出口側温
度検知器15を設け、それらとポンプP、ブロアーB、
加熱体3、切替器6を電気的に接続し、しかもこれらは
検知温度が触媒の反応温度に達したときにはじめてオン
・オフするようにすれば、反応器1内の温度が触媒の反
応温度以下になれば自動的に廃液の供給や空気の導入等
が停止される。■ As shown in the figure, an inlet side temperature sensor 13, an outlet side temperature sensor 15 are provided, and in addition to them, a pump P, a blower B,
If the heating element 3 and the switching device 6 are electrically connected and are turned on and off only when the detected temperature reaches the reaction temperature of the catalyst, the temperature inside the reactor 1 becomes the reaction temperature of the catalyst. If the conditions are below, the supply of waste liquid, the introduction of air, etc. will be automatically stopped.
従って反応器1内には残留ガスが殆んど残らなくなり、
運転再回時に反応器が爆発する慮れかなく、極めて安全
性の高いものとなる。Therefore, almost no residual gas remains in the reactor 1,
There is no possibility that the reactor will explode when it is restarted, making it extremely safe.
◇ 廃液を火により燃焼させるのではなく、触媒により
燃焼して化学分解させるものであるため煙やすすが一切
出す、従って14C等の放射性物質の排出が少なくなる
。◇ Since the waste liquid is not burned by fire, but is burned by a catalyst and chemically decomposed, no smoke or soot is emitted, and therefore the emission of radioactive substances such as 14C is reduced.
更に長年使用しても導出路4が詰って故障したり、煙や
すすにより環境が汚染されることもない。Furthermore, even after many years of use, the outlet passage 4 will not become clogged and malfunction, and the environment will not be contaminated by smoke or soot.
■ 反応器1からの排気を高温のまま排出すると排気中
の3Hが蒸気として外部に飛散するが、本考案では排気
により導入路7内の空気を加熱するため排気がその分だ
け冷却されて水滴になりその中の3Hが捕集される。■ If the exhaust from the reactor 1 is discharged at a high temperature, 3H in the exhaust will scatter outside as steam, but in this invention, the exhaust heats the air in the inlet passage 7, so the exhaust is cooled by that amount and becomes water droplets. and 3H therein is collected.
■ 触媒の反応中に常時導入路7から空気が導入される
ため、排気ガス中の140.3H等の放射性同位元素が
排出基準まで十分稀釈され、空中拡散することが可能に
なる。(2) Since air is constantly introduced from the introduction path 7 during the catalyst reaction, radioactive isotopes such as 140.3H in the exhaust gas are sufficiently diluted to the emission standards and can be diffused into the air.
