Description

[Detailed Description of the Invention] The present invention relates to a collective storage battery equipped with a catalyst that reacts oxygen gas and hydrogen gas generated during charging of the storage battery and reduces them to water.

Generally, when a storage battery is in use, especially during charging, water in the electrolyte undergoes electrolysis and decomposes into oxygen gas and hydrogen gas, which are released into the atmosphere. It was necessary to replenish water as needed.

Therefore, if a catalyst device is attached to each storage battery in order to return the generated gas to water and recirculate it to the storage battery, the purpose of simplifying the water replenishment work can be distantly achieved, but it is not possible to install an expensive catalyst device for each storage battery. The problem was that it was not a great deal in terms of price, and the storage battery required a fairly large space for ventilation.

The present invention eliminates the above-mentioned drawbacks by providing a storage box containing a plurality of single cells with a common catalyst device for each single cell, and converting the oxygen gas and hydrogen gas generated from each single cell into the catalyst. The device is characterized by being equipped with a storage tank for storing the water produced by the reaction in the device.

An embodiment of the present invention will be described.

Reference numeral 1 indicates a collective storage battery in which a plurality of single cells 2 are stored as a group in one storage box 3, 4 is an upper lid that seals the storage box 3, 5 is a space inside the storage box 3, and 6 is installed on the upper surface of the upper lid 4. 7 is a gas inlet of the catalyst device 6, 8 is a produced water flow downstream port, 9 is a produced water storage tank provided on the back side of the upper lid 4, 1
0 is a connecting pipe that communicates the produced water flow lower port 8 and the produced water storage tank 9, and 11 is a produced water outlet provided in the produced water storage tank 9.

Since the present invention has the above-described structure, the gas generated in each cell 2 of the collective storage battery 1 rises and fills the space 5, but is introduced into the gas inflow lower of the catalyst device 6 as shown by the solid line arrow. The resulting water is reduced to water by the catalyst device 6 and the resulting water flows through the downstream port 8.
The produced water storage tank 9 is connected to the water connecting pipe 10 as shown by the dotted arrow.
is stored in

When gas generation becomes slow, such as after charging is completed, the upper cover 4 can be opened and water can be added to the cell 2 whose liquid has been reduced using a dropper or a suitable container through the generated water outlet 11.

That is, a single catalyst device 6 common to a plurality of unit cells 2 causes a combination reaction of oxygen gas and hydrogen gas filling the storage box 3 to produce water, which is temporarily stored in the storage box 4.
By replenishing this to the original cell 2 when necessary,
Water can be easily replenished even in places where there is no water source nearby.

Furthermore, even when used in a narrow storage battery room, etc., it does not emit hydrogen gas, so ventilation equipment is not required and is safe.Even when used indoors or near instruments, there is no electrolyte droplet scattering, and the surrounding area is safe. There is no risk of acid corrosion.

As mentioned above, the present invention can charge the collective storage battery with the storage box sealed, and can efficiently collect the generated gas using a common catalyst device, reduce it to water, and store it for replenishing the storage battery. This has great practical value in that it is possible to use the catalyst device more efficiently than when a catalyst device is installed in each storage battery individually, and the storage battery room can be simplified and downsized without the need for ventilation equipment. .
