Abstract

PROBLEM TO BE SOLVED: To keep the extinguishing power of a fire extinguisher for a long time, and to sufficiently extinguish the fire even when the fire power is strong, by making a liquid absorption medium which is formed by the granular liquid absorbing polymer, impregnated with a fire extinguisher having the extinguishing function, to be sprayed. SOLUTION: The granular water absorbing polymer is used as a fire extinguisher to be filled in a cylinder 11 of an extinguisher 10, the polymer is impregnated with the water content, to be filled in the cylinder 11, and further the compressed air is filled in the same as a spraying means. To use the extinguisher 10, a safety plug 16 is removed first, and then a movable handle 15 is moved, to open a valve in a valve element 13, thereby the granular polymer impregnated with the water content, is ejected by the pressure of the compressed air, to be attached to a fire face of a burning body for cooling the same. The water capacity of the polymer of the liquid absorption medium is high, and the water holding property is also high, so that the polymer can cool the fire face in a condition that it is attached to the fire face for a long time, thereby the high extinguishing power can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing method and a fire extinguishing agent particularly effective for extinguishing a general fire (fire class A).

[0002]

2. Description of the Related Art As a fire extinguisher effective against general fires (fire type A) and oil fires (fire type B), there is a fire extinguisher.
When this fire extinguisher is turned over, the baking soda solution in the outer cylinder and the aluminum sulfate solution in the inner cylinder are mixed to generate carbon dioxide, and at the same time, a large amount of foam is generated, which is sprayed on the fire surface. It is a vessel.

Another method is to fill a cylinder with liquefied carbon dioxide and open the valve to release carbon dioxide and dry ice to extinguish the fire by a cooling effect. When the thermal power of the surface becomes strong, the above-mentioned bubbles and dry ice disappear immediately, and there is a problem that a sufficient fire extinguishing power cannot be obtained.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fire extinguishing method and a fire extinguishing agent which have a long extinguishing power of a fire extinguishing agent and can extinguish a fire sufficiently even with a strong heat.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a fire extinguishing method in which a liquid extinguishing agent having a fire extinguishing function is impregnated and sprayed into a liquid absorbing medium formed of a granular, liquid absorbing polymer polymer. Fire extinguishing method by impregnating and spraying a water-absorbing medium formed of a water-absorbing polymer polymer with water, and a fire extinguishing method formed by impregnating a liquid fire-extinguishing agent with a fire-extinguishing function in a granular, liquid-absorbing polymer polymer It is characterized by being an agent.

[0006]

According to the fire extinguishing method and the fire extinguishing agent of the present invention, a liquid fire extinguishing agent having a fire extinguishing function, for example, a liquid absorbing medium impregnated with water or liquid carbon dioxide is applied to the fire surface of a burning object. When sprayed, this liquid absorbing medium adheres to the fire surface and cools it, and the polymer polymer of the absorbing station medium holds a large amount of liquid fire extinguisher and also has a high retention, so it remains attached for a long time. The fire can be cooled to extinguish the fire, and a large fire extinguishing power can be obtained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The drawing shows a fire extinguisher, and in FIG.
Fixed a cap 12 on the top of a cylinder 11, attached a valve 13 to the cap 12, and attached a fixed handle 14
And the movable handle 15 are attached, and the movable handle 15 is moved so that the valve of the valve body 13 is opened. A safety plug 16 for preventing unexpected movement is attached to the movable handle 15, and the movable handle 15 is allowed to move by pulling out the safety plug 16. Further, a hose 17 is connected to the valve body 13,
The nozzle 18 is attached to the end of the.

As a fire extinguishing agent to be filled in the above-mentioned cylinder 11, a high molecular polymer which is granular and has water absorption (for example,
Nippon Shokubai Co., Ltd. Product name CA-W20)
This is impregnated with water and filled into a cylinder 11, and further,
Compressed air is sealed as a means for blowing the compressed air.

When using the fire extinguisher 10 constructed as described above, the safety plug 16 is removed, and then the movable handle 1 is used.
When the valve 5 is moved, the valve in the valve body 13 is opened, and the granular polymer polymer impregnated with moisture is jetted out by the pressure of the compressed air, adheres to the fire surface of the burning object, and cools it. At the same time, the polymer polymer of the water-absorbing medium has a large amount of water retention and high water retention, so that the fire surface can be cooled and extinguished in a state of being adhered for a long time, and a large extinguishing power can be obtained.

In the above-described embodiment, the polymer is impregnated with water. However, as another example, the above-mentioned cylinder 11 is charged with an appropriate amount of the polymer, and liquefied carbon dioxide is sealed therein. You can also. In this case, the polymer is impregnated with liquefied carbon dioxide.
