Description

Water fog spray device for fire extinguishing and fire fighting vehicle equipped with it {MIST INJECTION APPARATUS, AND FIRE ENGINE THEREWITH}

The present invention relates to a fire-fighting vehicle equipped with a fire fog spray device for fire extinguishing, and more specifically, it can be used for extinguishing spraying water particles in the form of fog to extinguish building fires and oil, electricity, gas fires as well as large forest fires. The present invention also relates to a firefighting vehicle equipped with a fire extinguishing water spray device that can be used as a device for spraying forest pest pesticides and known snow removal operations such as demonstration and suppression.

In the event of a fire, fire or water is used to extinguish the fire, and a sprinkler or water spray device is used for the fire. However, the conventional fire extinguishing method using water or foam liquid is limited to the spraying range, and is not suitable for extinguishing fires or forest fires in large buildings, and in particular, extinguishing a wide range of oil and gas fires. It is difficult. 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. This mist fire extinguishing method has already been proven and applied to some fire fighting systems.

However, in the conventional mist spray type fire extinguishing system or a fire extinguishing system using the same, the ability to spray the mist to a wide place or a long distance is insufficient, and most of them are adopted as a fixed method for the purpose of extinguishing a fire in a building, and also insufficient spraying ability. There is a problem that must be provided with a plurality of forced blowers and nozzles in order to supplement the. In addition, despite the actual fire extinguishing effect, in particular, the mobility and accessibility is limited, so the present situation has not been applied to the evolution of large forest fires or oil fires.

Accordingly, it is an object of the present invention, in view of this problem in the prior art, to include water particles in the accelerated jet air to spray the fog to a far or wide area fire source, thereby, a plurality of blowers and nozzles It is to provide fire extinguishing water spray device that can be removed by reducing assembly labor and convenient maintenance.

Another object of the present invention is to provide a fire extinguishing vehicle that is equipped with a fire fog spraying device for extinguishing a fire, an oil fire, or a fire in a large building.
