Water fog spraying device is mainly used for extinguishing and spraying water particles in the form of fog to extinguish large fires, as well as building fires, oil, electricity, and gas fires. Also used as.

In the event of a fire, fire or water is used to extinguish a fire, and a sprinkler or a spray device is used for the equipment. By the way, the conventional fire extinguishing method using water or foam liquid is limited to the spraying range, and is unsuitable for extinguishing fires and forest fires in large buildings, and is particularly difficult to extinguish a wide range of oil and gas fires. Do. Accordingly, various efforts and studies have been conducted to improve such a problem, and recently, a method of extinguishing a fire using fog has been proposed.

According to the fire extinguishing method using the fog, fine water particles are ejected toward the garden in the form of a mist, and the principle of extinguishing the garden by the cooling action in parallel with the asphyxiation is applied. That is, fine water particles form a mist layer between the flower source and the outside air to suffocate the flower source, and at the same time, water particles under the mist layer evaporate instantaneously by the flower source to perform a cooling action. These mist-fired fire extinguishers have already been proven and applied to some firefighting systems.

Hereinafter, with reference to the accompanying drawings will be described with respect to the conventional fog spray type fire extinguisher.

1 is an exploded perspective view of a conventional mist-fired fire extinguisher.

And a blower blade (30) coupled to one end of the main body (10) and coupled to the other end of the main body (10) to blow high pressure air toward the injector (20); It is configured to include a motor 40.

In the center portion of the injection means 20, a spray nozzle 22 is formed by spraying water, and the motor 40 rotates the blower blade 30 to finely spray the water particles sprayed from the spray nozzle 22 such as fog. Spread it away and blow it away. As such, the water particles diffused finely like fog have a very fast evaporation rate when they cover the fire source, so that the fire is momentarily cooled to extinguish the fire.

However, the mist spray type fire extinguisher blowing finely dispersed water particles using high pressure air as described above has a disadvantage in that the distance of water particles is very short compared to the case of spraying water using a general fire hose. . Moreover, the water distance becomes shorter as water particles are bonded to each other and become larger while being transported by high pressure air.

In addition, the conventional mist-fired fire extinguisher is combined with the injection means, the blow blades and the motor will be very large self-weight, such a heavy fire extinguisher is not good mobility and can not be used in a fire site that requires rapid mobility. There is a problem.

Therefore, in spite of the excellent fire extinguishing effect, the conventional mist-fired fire extinguisher has not been commercialized to date for the evolution of large forest fires or oil fires due to the limitation of the spraying distance and mobility.
