(1) Even if water is emitted after the fire reaches a moderate level, there is a problem that the fire is increased due to the H 2 and O 2 generated by the thermal decomposition of the steam. (2) Therefore, there are many cases where it is difficult to extinguish a combustible material until it burns out. (3) Also, it is toxic when halon, which is an inert gas, is used in chemical fire extinguishing. (4) Extinguishant requires refilling and maintenance.

(2) The exhaust gas 5a from the exhaust pipe joins and is mixed with the air flow 2a downstream of the mixed flow fan. (3) Further, the above mixture of air and exhaust gas is introduced into the ejector 6, and the water ejected from the water injection nozzle 8 located at the ejector introduction portion ejects water pumped from the engine-driven water pump 7 into the ejector. Due to the ejector effect, a large amount of water is sucked and atomized in the subsequent flow.

The mixed flow fan 2 driven by the engine 1 enables continuous flow of relatively high pressure air with a large air volume, and exhaust gas of the engine is discharged to the downstream of the mixed flow fan to further generate the above air and exhaust gas. A mixture of gas is introduced into the ejector 6, and high-pressure water is discharged from a water injection nozzle 8 that communicates with an engine-driven water pump 7 provided at an ejector inlet to generate a mixture of air, exhaust gas, and water injection inside the ejector. At the beginning of the fire, the mixed gas is blown onto the fire.

When the engine 1 is operated, the mixed flow fan 2 is passed through the drive shaft 3.
Is rotated to generate a high-pressure, large-volume air flow 2a. The air flow 2a is mixed with the exhaust gas flow 5a discharged into the air flow 2a. Further, these gases are added by the water injection nozzle 8 in the ejector 6 by the water injection 8a by itself and by the blowout, and these strong Gases of various pressures and volumes are blown into the fire early in the fire, allowing for immediate extinction. Since the torque damping device 4 is provided between the engine 1 and the drive shaft 3, the drive system is not subjected to excessive force due to the rapid acceleration / deceleration of the engine 1.

期瞬間防火が可能となる。The instant fire preventive device according to the present invention is constructed as described above, and the flame generated by the fire is blown away by the strong air flow of the mixed flow fan and the mixed flow of air and exhaust gas due to the ejector effect. Fire extinguishing water is sucked out at a high speed into a strong jet and flows out. In addition, since the pressure increases at the ejector outlet as much as the flow velocity decreases and the pressure is such that the fire is extinguished, the above-described actions and effects make it possible to prevent fire at the initial moment.
