Description

Detailed Description of the Invention "Industrial Application Field" The present invention uses a fire extinguishing agent that generates a fire extinguishing gas or absorbs heat from the surrounding area and generates water at the same time. This invention relates to a method and apparatus for extinguishing a fire in an emergency and immediate manner by shooting a lump of fire extinguishing agent that forms a film into a flame together with hot water.

``Conventional technology'' Traditionally, fire fighting has relied on the most primitive method of spraying water with a hose, and when spraying water over a strongly burning flame, it actually seems to intensify the flames. However, it is difficult to avoid the fire spreading due to its lack of immediate effect, and it is impossible to find a way to replace it with a more pronounced effect.

There is also a method of extinguishing a fire by spraying extinguishing powder using a fire extinguisher, but this device is not useful for wide-ranging, high-temperature fires, especially since the powder is slightly dispersed in the vicinity of the flame or on the outer surface. However, it is difficult to expect any effect such as extinguishing the flame inside the flame. Therefore, even in today's world of advanced science and technology, once a fire breaks out, there is no easy way to extinguish it, and in order to prevent the spread of the fire, buildings around the building are destroyed to prevent the spread of the fire.

``Problems to be solved by the invention'' Spraying water, which has little chemical extinguishing effect, on the outer surface of the flame has little extinguishing power for extinguishing strong flames, and the extinguishing effect is exerted directly inside the flame. That is difficult. Therefore, such methods should be fundamentally revised.

``Means for Solving the Problems'' In the present invention, the current state of a substance that exists or should exhibit a chemical extinguishing effect inside a powerful flame is determined not only on the surface, but also on the surface.
This provides a means to directly exert chemical extinguishing properties only after the chemical has been injected deep into the flame and has reached the interior of the flame.

"Embodiments and Effects" A detailed explanation will be given with reference to the accompanying drawings showing an example of the implementation of the present invention.
1 is a hollow sphere made of styrene resin with irregular molecular arrangement. Those with irregular molecular arrangement are brittle and have a high hardness, so if they are thrown into a flame, they will be destroyed, and they will absorb heat from the surrounding area by absorbing heat or using the powder of a known extinguishing agent used in known fire extinguishers, which is filled inside the fire extinguisher. Known fire extinguishing agent powder 2 that simultaneously removes water and generates water, and also forms a glass-like film on the surface of the burning material.
Scattered in flames. Then, by heating, the extinguishing agent powder disperses chemical extinguishing gas such as carbon dioxide into the flame, or absorbs surrounding heat through an endothermic reaction and simultaneously produces water,
Furthermore, it creates a glass-like film on the surface of the burning material, which obstructs the supply of oxygen, prevents combustion, and provides an immediate fire extinguishing effect. 3 is a well-known jet type hot air pump, water and sphere 1 are optionally permanently placed in the container 4 through valves 5 and 6, etc., and the water and the like are flowed out in the direction of fire hose 8 through valve 7. It is something to do. Reference numeral 9 denotes a driving high-pressure water pipe, and 10 denotes a gas introduction hole, which is reduced by a nozzle 11 and injects air or extinguishing gas from the gas introduction hole 10 and the driving high-pressure water pipe into the hose 8 at high pressure. The water in the hose flowing from the container 4 in the saddle and the sphere 1 filled with fire-extinguishing powder 2 are strongly jetted from the hose end 12 in the desired direction by the high pressure of this jet-like fluid. It is something. In the art, a sphere with great hardness falls or collides with the room and is destroyed, and then leaps into the midst of the flames 13 inside the room. However, since the sphere is filled with fire-extinguishing powder 2, the powder explodes and scatters, and the flame is filled with fire-extinguishing gas such as carbon dioxide gas generated by vaporization. It absorbs heat from the surrounding area and generates water, which also forms a glass-like film on the surface of the burning material, obstructing the supply of oxygen, and working with the injected extinguishing water to extinguish the fire immediately. It extinguishes the fire directly. still,
In the figure, 14 is a fire engine. In carrying out the present invention, the driving high-pressure water pipe 9, the gas introduction hole 10, the hose tip 12, etc. are molded into an integral rigid body that is easy to arbitrarily manipulate.
Firefighters, etc. should hold it arbitrarily on top of a ladder, etc., and use it by selecting the direction, etc.

``Effects'' The present invention has the above-described configuration, and since water and a sphere filled with extinguishing agent are mixed and injected into the flame from the hose tip 12 in a jet style, it is effective directly and immediately. It exhibits a fire extinguishing effect that is incomparable to conventional water extinguishing effects, extinguishes fire quickly, and prevents the spread of fire.
