2. Description of the Related Art As is well known, an acetylene gas cylinder is filled with a solid mass such as calcium silicate wetted with a solvent such as acetone or dimethylformamide. When the acetylene gas is charged, the heat of compression of the acetylene gas and the heat of dissolution are generated when the acetylene is dissolved in acetone. Therefore, conventionally, a large number of acetylene gas cylinders are erected and arranged in a row on an acetylene gas filling stage, and a connector derived from the acetylene gas supply path is connected and connected to the container valve of each acetylene gas cylinder, and the acetylene gas cylinder is connected to the room temperature (heat treatment). (Not performed) was filled while showering the water to absorb the heat generated during the filling.

[0003]

However, in the conventional acetylene gas filling technique, since the showering is being performed on the gas cylinder being filled, the cooling water that has flowed down scatters after hitting the surface of the gas cylinder and scatters. There is a problem that the floor is flooded. In addition, the degree of contact between the cooling water and the gas cylinder that falls is different between the gas cylinders, and the degree of cooling tends to be uneven, and the filling rate is based on the slowest cooling. There was a problem of becoming.

An object of the present invention is to provide a method and an apparatus for filling acetylene gas which can quickly fill a plurality of acetylene gas cylinders by focusing on such points.

[0005]

According to one aspect of the present invention, there is provided an acetylene gas supply path in which acetylene gas cylinders are accommodated in a plurality of columns and rows in a gas container container with the acetylene gas cylinders standing upright. Connected to the container valve of each acetylene gas cylinder to supply cooling water into the gas container container and to overflow acetylene gas into the acetylene gas cylinder in a state where it overflows from a position higher than the position corresponding to the container valve arrangement. In the invention according to the second aspect, the container valve of the acetylene gas cylinder in which the side wall of the gas container container accommodating the acetylene gas cylinder in a state of being arranged in a plurality of rows and a plurality of columns is arranged upright in the container. Formed higher than the height corresponding to
The cooling water cooled by the refrigerator can be supplied into the gas container.

[0006]

According to the first aspect of the present invention, an acetylene gas cylinder is accommodated in a gas container in a plurality of rows arranged in a plurality of rows, cooling water is supplied into the gas container, and the cooling water is supplied to the gas container. The cooling water does not scatter to the work site because it overflows from the upper part of the side wall. Further, since the cooling water can be uniformly brought into contact with all the gas cylinders, the gas cylinders can be cooled uniformly and quickly, and can be filled at a high filling rate.

Furthermore, since the overflow position from the gas container container is formed at a position higher than the valve arrangement position of the gas cylinder housed therein, the continuation position between the container valve and the gas filling connector is the container position. It becomes submerged in the cooling water inside, and bubbles are generated at the time of leakage, so that leakage can be found quickly.

FIG. 1 shows an embodiment of the present invention.
The symbol (1) in the figure is an acetylene gas cylinder to be filled, (2)
Numeral denotes a gas container container serving as an acetylene gas filling stage. The gas container container (2) is adapted to accommodate acetylene gas cylinders (1) in a plurality of rows and a plurality of columns (6 rows and 4 columns in the figure).

The gas container container (2) is formed in a box shape having an open ceiling, and a acetylene gas cylinder (1) carry-in / out opening (4) and a carry-in / out opening / outlet are formed in a peripheral side wall (3) thereof. An opening / closing door (5) for sealing (4) is arranged. The gas container (2) is formed in a watertight structure.

[0010] A cooling water supply port (6) is provided near the bottom of the gas container container (2).
A drain port is formed in the bottom wall of (2). Further, an overflow port (7) for cooling water is formed by slightly cutting off the upper end edge of a part of the peripheral side wall of the gas container container (2). And this overflow port (7)
It is formed at a position higher than the height corresponding to the container valve (8) disposed above the acetylene gas cylinder (1) which is erected inside the gas container container (2).

The cooling water supplied to the gas container (2) is cooled to 10 ° C. by using a refrigerator (not shown).
The following water is used. In addition, the cooling water that has overflowed from the gas container container (2) and the cooling water extracted from the gas container container (2) after the acetylene filling operation has been completed are circulated and used.

In the acetylene gas filling system configured as described above, acetylene gas cylinders are arranged in a plurality of rows and a plurality of rows in an upright state in a gas container (2).
The connector (10) derived from the acetylene gas supply passage (9) is connected to the container valve (8) of each acetylene gas cylinder (1), and the cylinder loading / unloading port (4) of the gas container container (2) is opened / closed ( Seal in 5).

Next, acetylene gas is supplied to the acetylene gas cylinder (1) while supplying cooling water cooled by using a refrigerator into the gas container (2). The cooling water in the gas container container (2) is stored from the bottom and finally overflows from an overflow port (7) formed in the upper edge of the side wall of the gas container container. At this time, acetylene gas cylinder
(1) is immersed in the cooling water in the gas container (2), and in the gas container (2), by convection phenomenon,
Since the warmed cooling water moves to the upper part, the overflowing cooling water overflows from the overflow port (7) after absorbing the heat generated during acetylene filling. As a result, each acetylene gas cylinder is even,
In addition, cooling is performed quickly, and uniform filling can be performed at a high filling speed.

Further, since the overflow port (7) is formed at a position higher than the height corresponding to the position of the container valve (8) in the acetylene gas cylinder (1) standing upright, the overflow of the acetylene gas is prevented. When filling, this container valve (8)
And the connecting device (10) connected to it will be immersed in the cooling water, so even if a leak occurs due to poor connection, the leak gas will be bubbles, so it is possible to find the poor connection early. Accidents can be prevented beforehand.

Further, since each acetylene gas cylinder (1) is immersed in the cooling water during the filling operation, even if a decomposition explosion occurs, the explosion pressure is absorbed by the water. Damage can be reduced.

After completion of the filling operation, a drain port formed in the bottom wall of the gas container container (2) is opened to open the gas container container.

[0017]

According to the present invention, an acetylene gas cylinder is accommodated in a gas container in a state of being arranged in a plurality of rows and a plurality of rows. Because of the overflow, the cooling water does not scatter to the work site. Further, since all the gas cylinders can be in uniform contact with the cooling water, the gas cylinders can be cooled uniformly and quickly, and can be filled at a high filling speed.

Further, since the overflow position from the gas container container is formed at a position higher than the valve arrangement position of the gas cylinder accommodated therein, the connection position between the container valve and the gas filling connector is changed to the container position. The submersion will be submerged in the cooling water inside, and bubbles will be generated at the time of leakage, so it is possible to quickly find the leak, and because the filling operation is performed with the gas cylinder submerged, the decomposition explosion may occur Even if it occurs, the explosion pressure is absorbed by the cooling water, so that damage can be reduced.
