本発明は蓄電池から発生する酸素、水素、混合
ガスを触媒反応によつて再結合させる熱放散、生
成水蒸気の凝縮を妨げない蓄電池用触媒栓に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a catalyst plug for a storage battery that does not hinder heat dissipation that recombines oxygen, hydrogen, and a mixed gas generated from a storage battery through a catalytic reaction, and condensation of the generated water vapor.

３の上面をおおうため、放熱抵抗となり、放熱に
有効な面積が減少し、生成水蒸気の凝縮が妨げら
れ触媒栓の性能が低下する欠点があつた。 In the catalyst plug, the oxygen/hydrogen mixed gas that has flowed into the interior through the lower water return port 6 passes through the catalyst container 1 made of a porous alumina sintered body, reaches the catalyst 2, and reacts therewith. Water vapor is generated by this reaction, and this water vapor releases latent heat and condenses on the inner wall of the outer vessel 3. Further, this reaction is an exothermic reaction, and a large amount of heat is generated, but this heat is also released to the outside through the outer container 3. In this way, the outer container 3 has the role of discharging the heat generated in the catalyst plug to the outside of the catalyst plug.
It plays the role of condensing the generated water vapor. Therefore, if the heat dissipation of the outer container 3 is hindered, the temperature of the outer container will rise, and the condensation of water vapor will be prevented. However, in the conventional catalyst plug, the outer container 3
There is an exhaust hole 4 at the top of the casing, and the explosion-proof filter 5 also covers the top surface of the outer container 3, which creates resistance to heat radiation, reduces the effective area for heat radiation, and prevents condensation of generated steam, resulting in a reduction in the performance of the catalyst plug. It was hot.
この欠点を除くため、蓄電池に使用するフイル

ある。 In order to eliminate this drawback, it may be possible to reduce the size of the filter used in the storage battery. However, when supplying power to a load with a storage battery in a floating charging state, if the filter becomes small, a large charging current will flow due to a failure of the charging rectifier, etc.
If a large amount of gas is generated and is discharged as unreacted gas, there is a possibility that explosion-proof performance cannot be guaranteed.

爆フイルタ内に開口していることを特徴とする。 The present invention overcomes such drawbacks of the conventional art and effectively uses the surface of the outer vessel for dissipating reaction heat and condensing water vapor to improve the return water efficiency of the catalyst plug. A ceramic catalyst container containing catalyst material is placed inside the outer container, which is integrated with a bottom part that has an annular slope that slopes downward toward the water return port that opens to the water return port. In a catalyst plug for a storage battery that recombines gas and refluxes water into an electrolytic solution, an exhaust pipe is provided in close proximity to a side wall surface of the outer container whose temperature is lower than the temperature of the central part of the outer container, and the exhaust pipe is An annular shape having a substantially U-shaped cross section, which passes through a hole bored in the annular inclined surface, has one end opening at the height of the upper end of the catalyst container, and has the other end adhered to the outer wall surface of the annular inclined surface. It is characterized by an opening inside the explosion-proof filter.
本発明の説明に先立つて、本発明を想起する基
礎となつた従来の触媒栓の動作状態について、触
媒栓内の水蒸気凝縮面及び温度分布に関し、触媒
栓のモデル実験による検討結果を述べる。 Prior to explaining the present invention, we will discuss the operating conditions of a conventional catalyst plug, which was the basis for conceiving the present invention, and the results of a study conducted on a catalyst plug model experiment regarding the water vapor condensation surface and temperature distribution within the catalyst plug.
第２図はモデル触媒栓における水蒸気の凝縮面
図、第３図は同じく温度分布図を示す。 FIG. 2 shows a water vapor condensation surface diagram in a model catalyst plug, and FIG. 3 similarly shows a temperature distribution diagram.
その結果、水蒸気が凝縮しない面は、第２図に

高い部分が存在し、栓内の底部に近づくにつれて
低くなつている。この現象から温度の高い部分
に、外部との放熱抵抗となるものは設けず、むし
ろこの部分からの放熱を促進する構造とすること
が望ましいと判断される。 As a result, surfaces on which water vapor did not condense were found at the upper part A and the lower part C of the outer container 3, as shown in FIG. Furthermore, according to the measurement of the temperature distribution inside the stopper at this time, as shown in FIG. 3, there is a high temperature part at the top of the stopper, and the temperature decreases as it approaches the bottom of the stopper. From this phenomenon, it is judged that it is desirable not to provide a heat dissipation resistance to the outside in a high temperature part, but rather to have a structure that promotes heat dissipation from this part.
そこで本発明では、排気孔の設置位置として
は、温度の高い外器３の上部をさけ、温度が低く
放熱にはそれほど関係しない外器の底面を選ん
だ。第２図、第３図において、Ｘはφ150mm、Ｙ
は250mm、Ｐは触媒容器を示す。 Therefore, in the present invention, as the installation position of the exhaust hole, we avoided the upper part of the outer case 3 where the temperature is high, and chose the bottom surface of the outer case where the temperature is low and does not have much effect on heat radiation. In Figures 2 and 3, X is φ150mm, Y
is 250mm, P indicates the catalyst container.
つぎに本発明を図面にもとづいて説明する。 Next, the present invention will be explained based on the drawings.
本発明の一実施例を第４図に示す。外器をドー
ム型に形成した。この構造は凝縮した水滴が流下
し易い構造であれば良く、必ずしもこの型に限る
ものではない。 An embodiment of the present invention is shown in FIG. The outer vessel was formed into a dome shape. This structure may be any structure that allows condensed water droplets to easily flow down, and is not necessarily limited to this type.

に変えることができる。 At the periphery of the cylindrical water return port 6 at the bottom of the outer container 3, there is an annular inclined surface 1 that slopes downward toward the water return port 6.
The hole 13-2 passing through 3-1 is connected to the outer container 1 with a low temperature.
An opening 14- is bored close to the inner wall 13A of the catalyst container 1, passes through the hole 13-2, and is inserted into the outer container from the bottom of the annular inclined surface 13-1, with one end reaching the height of the catalyst container 1. 1 is provided. By changing the inner diameter and length of the exhaust pipe 14, the exhaust resistance within the plug or the position of the opening 14-1 can be freely changed.

A plan view of the explosion-proof filter 15 is shown in FIG. The water return port 6 has a semicircular top and bottom board 7.
will be established.
次に本発明の触媒栓における動作を説明する。 Next, the operation of the catalyst plug of the present invention will be explained.
本発明の触媒栓では、還水口部６から導かれた
酸素・水素ガスは触媒材２に到達して反応する。
反応で生成した水蒸気は外器１３において潜熱を
放出して速やかに凝縮し、内壁面を伝わつて還流
する。また外器１３の上部には放熱効果を妨げる
付属物は何等設けられていないので反応による生
成熱も容易に外気と熱交換することができる。 In the catalyst plug of the present invention, the oxygen/hydrogen gas led from the water return port 6 reaches the catalyst material 2 and reacts therewith.
The water vapor generated by the reaction releases latent heat in the outer vessel 13, quickly condenses, and refluxes through the inner wall surface. Further, since no attachments are provided on the upper part of the outer container 13 to impede the heat dissipation effect, the heat produced by the reaction can be easily exchanged with the outside air.
さらに本発明では排気孔と防爆フイルタは外器
の下部に設置されているが、この部分は外器の他
の部分と比較しても温度が低い部分なので、防爆
フイルタを設置しても熱抵抗にはなりにくい。 Furthermore, in the present invention, the exhaust hole and the explosion-proof filter are installed at the bottom of the outer case, but since this part has a lower temperature compared to other parts of the outer case, even if the explosion-proof filter is installed, there will be no thermal resistance. It is difficult to become.
ところで排気孔が外器の底面に単なる小孔で設
けられた場合には、酸素・水素ガスは触媒栓の内

てしまう恐れがある。 However, if the exhaust hole is simply a small hole provided on the bottom surface of the outer container, there is a risk that the oxygen/hydrogen gas may be discharged to the outside from the exhaust hole before it has sufficiently penetrated into the inside of the catalyst plug.
この問題を本発明の触媒栓では、排気孔に連通

る。 In the catalyst plug of the present invention, this problem is solved by changing the flow resistance and gas flow path by providing a pipe communicating with the exhaust hole. In other words, in the present invention, by changing the diameter of the pipe, the flow resistance during gas discharge changes, and by changing the length of the pipe used when providing the exhaust pipe from the bottom of the outer container to the inside of the catalyst plug. The relative position of the container and the open end 14-1 of the exhaust pipe can be changed. As a result,
The oxygen/hydrogen gas passes near the catalyst container and then heads toward the opening 14-1 of the exhaust pipe, during which time it can react with the catalyst material. Therefore, according to the exhaust pipe of the present invention, by changing the position of the opening in the catalyst plug, the flow resistance and flow from the introduction of the oxygen/hydrogen gas to the exhaust can be changed, and the flow between the catalyst and the oxygen/hydrogen gas can be changed. It can be operated up to the point of contact.
また排気管のパイプを外器の温度の低い壁１３

の損失も少ない。 In addition, the pipe of the exhaust pipe is connected to the low temperature wall 13 of the outer vessel.
By installing it near A, a low temperature fluid (mixture of generated water vapor and unreacted gas) cooled by the outer vessel
is discharged. In general, regarding the amount of water contained in a gas and its temperature, if the relative humidity is constant, the lower the temperature, the lower the amount of water contained in the gas. Therefore, in this case as well, if the amount of fluid discharged per unit time is the same, the amount of water discharged to the outside will be smaller if the fluid with a lower temperature is discharged.
The method of the present invention, which discharges the low-temperature fluid near the wall, causes less loss of generated water vapor than the conventional catalyst plug.

の変更を含んでいる。 In the embodiments of the present invention, the shape of the outer container is dome-shaped, but the present invention is not limited to this.In order to promote the flow of water droplets and to effectively dissipate heat, the outer container has a heat dissipation structure. providing fins for
Alternatively, in order to improve the cooling effect, changes may be made without departing from the spirit of the present invention, such as a bellows structure.
本発明の外器は底面を除いて全て発生熱の放熱

縮も促進される。 The entire outer container of the present invention, except for the bottom surface, can participate in the radiation of generated heat and the condensation of water vapor. Therefore, the generated heat is also easily released to the outside, and the condensation of water vapor is also promoted.
