Description

Description: TECHNICAL FIELD The present invention relates to a storage container for gas cylinders, and in particular, supplies liquefied petroleum gas (LPG) to consumers such as ordinary houses, apartment houses, commercial and industrial uses. Therefore, the present invention relates to a so-called cylinder house, which stores a required number of LPG cylinders and sends LPG from each cylinder.

[Conventional technology]

The conventional storage container for this type of gas cylinder is one in which a slate roof is provided in the storage container body made of reinforced concrete or reinforced concrete block, and the installation part of the LPG cylinder is provided on the internal floor surface. The surface is made of concrete. The LPG gas is sent to the outside from the container valve of these gas cylinders through the collecting device, the gas pressure is adjusted by the pressure adjusting device.

[Problems to be Solved by the Invention]

Needless to say, it is necessary to take sufficient measures against LPG leakage in the storage container of the gas cylinder as described above.
In this case, in order to prevent the concentration of leaked LPG from increasing locally, even if a leakage accident should occur, disperse this as much as possible into the outside air to avoid increasing the concentration locally. desirable. In addition, as a measure against leakage, the LPG is about 1.5 times the specific gravity of air, and the leakage LP
It must be taken into account that G has the property of spreading across the floor.

However, as mentioned above, the conventional gas cylinder storage
Since the floor surface was made of concrete and no ventilation was provided under the floor, the larger the number of cylinders installed per floor area, the poorer the ventilation efficiency and the stronger the tendency for leaked LPG to stay on the floor surface. Therefore, there was a risk that the leaked LPG concentration would be locally high.

Therefore, according to the present invention, by providing a ventilation means at the lower part of the floor surface, even if LPG leaks, it is possible to completely prevent gas retention, and to improve the gas permeability of a gas cylinder with high gas generation efficiency from the cylinder. The purpose is to provide a storage.

It is the support step 14 of the.

The same support step 14 includes front wall 2, rear wall 3 and both side walls 5, 6.
Also formed. Further, a ventilation port 15 communicating with the outside air is provided between the support step portions 14. Each of the support steps 1 above
When the grating 13 is placed and laid on 4, the upper surface of the grating 13 coincides with the upper surface of the working passage 10, and the upper surface of the grating 13 becomes the gas cylinder installation portion 16, and
A ventilation passage 17 equal to the height of the support step 14 is formed below the grating 13. Therefore, each ventilation passage 17
The ventilation port 15 forms a passage open to the outside air, and the passages 12 communicate with each other.

The gas cylinder 12 is installed on the grating 13.
When LPG leaks from these gas cylinders 20, since LPG has a larger specific gravity than air, it flows into the ventilation passage 17 through the gap of the grating 13, and in some cases moves to the other ventilation passage 17 through the communication passage 12. Then, it is discharged to the atmosphere through the required ventilation port 15.

In order to promote discharge to the ventilation port 15, the ventilation passage 1

And a fan 26 'is attached.

In the above case, the fan 26 is always operated to create a flow of air in each ventilation passage 17. Then LPG
When the leakage occurs, the LPG passes through the grating 13, is sucked into each ventilation passage 17, and is forcibly discharged from the chimney 23 to the outside air.

Next, the embodiment of the third means shown in FIG. 9 to FIG.
Support legs 28 are provided on the lower surface of the storage case main body 1 and are thereby separated from the base surface 29 by a required height.

〔The invention's effect〕

As described above, the first to third means of the present invention are basically based on the structure in which the grating is laid on the floor surface of the gas cylinder installation portion and the discharge passage communicating with the outside air is provided below the grating. With the configuration, LPG leaked from the gas cylinder can be promptly discharged to the outside air without being retained on the floor surface.

As in the first method, natural ventilation is effective when there is no fire point in the vicinity of the cylinder house, and the convection of air due to ventilation supplies the heat source for vaporization of LPG, increasing the amount of heat generation. Has the effect of promoting. In addition, the configuration in which the plurality of ventilation passages are communicated with each other by the communication passage has an effect of facilitating the leakage gas to move to a lower resistance.

Like the second means, the one provided with the suction-type forced ventilation device discharges the leaked gas accumulated in the communication passage which is cut off from the outside below the grating from the chimney, so that the leaked gas contained in the exhausted gas is discharged. Has a high concentration and therefore a high emission efficiency. In addition, since the air flow is further promoted compared to natural ventilation, the supply of heat source for vaporization becomes active,
It has the effect of further increasing the amount of heat generation.

Further, as in the third means, the LPG provided with the pressure-feeding type forced passage device having an independent drive source can supply the heat source for vaporization regardless of the temperature condition of the LPG. Therefore, the amount of heat generation can be increased.
