Description

[Detailed description of the invention] The present invention relates to a fire extinguishing method.

Conventionally, various methods have been used to extinguish fires, including water spraying, extinguishing agent injection, spraying, and gas injection.

However, extinguishing a fire by spraying water generally requires the installation of a fire hydrant and requires time for preparation before spraying water.
There are many problems in terms of cost and preparation for extinguishing fires, and in apartment complexes, water damage is often caused by spraying water onto the downstairs areas.

Extinguishing agents and halon gas are effective at the initial stage of extinguishing a fire, but they are not effective against a fire that has spread.

As a result of repeated research, the present invention has been developed to compensate for these shortcomings, to quickly and easily extinguish a fire that has spread, and to protect precious human lives and valuable assets from fire. He invented a method of extinguishing fires by utilizing

Originally, a fire is a phenomenon in which a combustible object is ignited from an ignition source and burns continuously, but in this combustion, carbon combines with oxygen in the air due to high temperatures and continues to burn.

Therefore, by irradiating the carbon atoms with a laser beam, the electrons of the carbon atoms are caused to move, making it impossible to combine with oxygen even at high temperatures, thereby inhibiting continuous combustion. That is, by irradiating a carbon atom (see FIG. 1) with a laser beam having a specific wavelength, the electrons in the carbon atom are stimulated to move to other electron shells. In other words, the electron receives energy from the laser beam and moves to an electron shell with a higher energy level than the electron shell it is currently in. (See Figure 2) Furthermore, when the electron returns to the electron shell with a lower energy level, it releases a large amount of energy.

In this way, continuous combustion is inhibited by the instantaneous continuous repetition phenomenon, and the fire is immediately extinguished.

Although it has already been established as a theory that electrons move between electron shells, there is still no idea how to utilize this in a fire extinguishing method.

The present invention has the following features and effects.

(1) Laser beam emitting devices are lightweight and can be transported and operated by a single person, so after a fire is discovered (including when reported), the time it takes for the public fire brigade to arrive at the scene is shortened, and water can be emitted. 1) There is no need to extend the hose for fire extinguishing, and the time required to start fire extinguishing work is greatly shortened.

The most important requirement for extinguishing a fire is to shorten the time from the outbreak of the fire to the start of extinguishing work, and the present invention greatly reduces the damage caused by fire. In particular, in the event of a major earthquake, most of the water pipes and fire hydrants would be destroyed by the seismic motion, making water spraying impossible. However, since the present invention uses laser beams, it is effective for post-earthquake firefighting. It's extremely effective.

(2) Instantly extinguishing a flaming fire and preventing the spread of the fire Normally, in the case of a wooden house, the time from ignition to a flaming fire is 3 to 5 minutes, and the time it takes for a fire to spread to a neighboring house is 8 minutes. It is said to be a minute. In particular, given the overcrowding in urban areas, once a fire breaks out, there is a high possibility of it spreading, and cities have experienced many large fires in the past. Therefore, fire extinguishing operations in the early stages are extremely important.

Therefore, various firefighting equipment and firefighting defense tactics have been researched and developed, but they cannot be said to be perfect yet. 1. The present invention extinguishes a fire instantly and over a wide area by irradiating a laser beam, which solves the conventional problem of requiring a long time to extinguish the fire after starting the fire extinguishing operation, and also minimizes the spread of the fire. It can be suppressed.

Furthermore, unlike in the past, there is no longer any delay in extinguishing fires due to insufficient water availability even after firefighting operations begin.
It is expected that it will be effective against fires in high-rise buildings.

As described above, the present invention brings about an epoch-making effect on fire prevention and greatly contributes to society.
