Will be.

As described above, in the two-fluid fire extinguishing apparatus according to the present invention, since the extinguishing liquid sprayed for fire extinguishing is mixed and sprayed with nitrogen gas at high pressure, mist spraying of fine particles rapidly penetrating into the fire source is made, so that the extinguishing liquid is uniform. Distribution and efficient extinguishing, as well as fire can be extinguished early in the shortest time. In particular, since the sprayed extinguishing fluid is mixed and sprayed with nitrogen gas, the sprayed extinguishing fluid is stored in the fire area. Although partially applied to, it is not penetrated inside by nitrogen gas and only gets on the surface.

Therefore, in the process of spraying the nitrogen gas and the extinguishing liquid sprayed through the two-fluid spray nozzles 60, they are mixed with each other and sprayed into fine particles, thereby forming a foam form having a predetermined adhesiveness rather than a general liquid (moisture) state. It does not penetrate into electronic devices or electronic products, but is applied only to the surface to prevent secondary damage caused by moisture.

 As such, by using the two-fluid extinguishing spray apparatus according to the present invention, by mixing and spraying the extinguishing liquid for extinguishing with nitrogen gas, it is possible to improve the extinguishing power and to extinguish the fire early within a short time, it is efficient, spraying during fire extinguishing It is possible to prevent the extinguishing fluid from penetrating into the electronic device and the product, and to prevent secondary damage due to moisture, thereby ensuring safety due to fire extinguishing, and economically minimizing the damage caused by fire. You can get the effect.

In addition, the present invention is an environmentally friendly, low cost and high efficiency to prevent the environmental pollution such as air and water pollution by the fire extinguishing liquid sprayed for fire extinguishing, as our pure technology, such as import replacement effect A great effect can be obtained.
