2. Description of the Related Art At present, the types of fire combustibles are increasing more and more. Generally, fresh water is radiated and sprayed, or various fire extinguishing agents of powder type or foam solution type are used. It is known to use a solid fire extinguishing agent which has been pulverized so as to easily dissolve the agent and then mixed and dissolved. Recently, a fire extinguishing agent composed of monoethanolamine and phosphoric acid has been studied.

However, when radiating fresh water, especially in firefighting of multi-story buildings such as high-rise buildings and condominiums, a large amount of water is used. Even to parts that are not directly related,
Water splashes, outflows, and water leaks often cause significant damage due to so-called water damage. This is a common problem that applies not only to multi-storey buildings but also to ordinary houses.
Until now, except for some parts, most have relied on fire extinguishing using fresh water, so house fires, seismic disasters, forest fires, etc., which have poor water access,
It was necessary to use limited water efficiently.

Further, powder-type or foam solution-based fire extinguishing agents have a higher fire extinguishing ability than water, but are more expensive than water, and are often focused on use in special cases such as industrial complexes and aircraft fires. I was Furthermore, in the case of a large-scale fire such as a forest fire, the solid fire extinguishing agent is pulverized so that it can be easily dissolved in water, mixed and dissolved, and then dissolved in water. Spraying is used, but a device for dissolving the solids is required, and the operation is complicated, which is not always practical.

[0005] In addition to the fire extinguishing problem described above, another problem after fire extinguishing is that fresh water can be dried and recovered by leaving it to stand for a certain period of time. As a result of emphasizing only the fire extinguishing performance of fire extinguishing agents, measures after fire extinguishing, that is, removal of fire extinguishing agents including foam extinguishing agents, become a major issue. In addition, a considerable amount of water must be removed by washing, and there are difficulties in cleaning up after the fire extinguishing, and time, labor and cost for the fire extinguishing.

%), 56 and 96 parts by weight of monoethanolamine (hereinafter abbreviated as MEA), and the amount of water is 35 parts.
The application state when changing to ~ 110 parts by weight was examined.
This concentrated fire extinguishing liquid is usually composed of the specified amount of phosphoric acid, MEA and water in the concentrated state. When used, this concentrated fire extinguishing liquid is diluted and used, but it is clear from experiments that the amount of water in the concentrated fire extinguishing liquid is not always possible, and that an optimal amount is required. .

In other words, when used, it is necessary to extract a specified amount of the concentrated fire extinguishing liquid and mix it with water. For this purpose, a certain degree of viscosity is required. In this example, this mixer was examined using a gear pump (manufactured by Kyowa Chemical Co., Ltd.), which is easy to dilute into water. The experiment was conducted at a temperature of minus 20 ° C., at which the viscosity becomes particularly high. Experiments have shown that the outflow from the pump decreases sharply when the amount of water added is too large or, conversely, too small. The following shows the relationship between MEA and water at −20 ° C.

Obazoline LB (manufactured by Toho Chemical), which is generally used, such as shampoo, was used as a surfactant, and 3 parts by weight of this was used as a concentrated fire extinguishing liquid. This concentrated fire extinguishing liquid was mixed so that the mixing ratio with respect to 200 parts by volume of water was 2.5 parts by volume.
Using a fire model, a fire extinguishing efficiency experiment based on pH change was performed. The following table shows the efficiency when the pH is changed with the above composition of the concentrated fire extinguishing liquid, where the efficiency in extinguishing fire with water alone is 1.

On the other hand, the efficiency increases as the pH decreases. Actually, when the pH is 2.5, the efficiency is about twice as high as that when only water is used. However, according to past experience, a strong acid having a pH of 2.5 is not practical even though it is a concentrated fire extinguishing liquid. From the viewpoint of efficiency, p
In the case of H6.5, since it was almost the same as water, it was found that the practicable pH of the concentrated fire extinguishing solution was in the range of 3 to 6.

[Embodiment 3] In the present embodiment, the composition of the concentrated fire extinguishing solution similar to that of the embodiment 2 is shown by changing the dilution amount and specifically showing the fire extinguishing efficiency when the pH is set to 3. The table below. As can be seen from the table, assuming that the efficiency when only water is used is 1, as the dilution amount is reduced (when the amount of the concentrated fire extinguishing liquid is increased), it is almost impossible for 1 volume part to 200 volume parts of water. As with water, it has no effect as a fire extinguishing agent, but its effect can be seen when it exceeds 1.2 parts by volume. From the above results, the dilution amount was water 2
It was found that 1.2 volume parts or more was necessary for 00 volume parts.
