Problems solved by technology

[0003] Halon is a fire extinguishing agent that achieves the purpose of extinguishing fires through cooling effect and chemical action, but since the fire extinguishing agent itself is decomposed by the heat generated by the fire to generate acid gases such as hydrogen fluoride, it is problematic from an environmental point of view
In addition, since inert gases such as carbon dioxide extinguish fires by reducing the oxygen concentration in the room, they cannot be used when people stay in the room, and there is room for improvement in terms of safety.

Embodiment Construction

[0059] Hereinafter, embodiments of the foam generator of the present invention will be described in detail with reference to the drawings.

[0060] figure 1 A high-expansion foam fire extinguishing device 1 as one embodiment of the present invention is shown, and the high-expansion foam fire extinguishing device 1 of this example includes an internal air type foam generator 10 .

[0061] The foamer 10 includes a cylindrical main body 11 , a foaming net 12 provided at the front end opening of the main body 11 , and a nozzle 13 arranged inside the main body 11 .

[0062] The main body part 11 is cylindrical in this example. The shape of the body part 11 is not particularly limited as long as it can hold the foam net 12 and the nozzle 13 at predetermined intervals. The main body part 11 may be, for example, a cylindrical shape having a polygonal or elliptical cross section, or may not be a cylindrical shape. In the main body part 11, a bracket for installing the foamer 10 can ...

Abstract

The invention provides a high-expansion foam fire extinguisher which can exert appropriate fire extinguishing performance according to the occurrence condition of a fire disaster. This high-expansionfoam fire extinguisher (1) is characterized by being provided with: a nozzle (13) that sprays a foam solution supplied from a foam solution supply device via a foam solution pipe (14); a foam net (12)through which the foam solution ejected from the nozzle (13) passes to generate foam; and an adjustment unit (15) that adjusts the foaming ratio by changing at least one of the injection pressure ofthe foam solution injected from the nozzle (13) and the amount of air supplied when the foam is generated by the foaming net (12).

Description

technical field [0001] The present invention relates to a high-expansion foam fire extinguishing device installed in ships and the like. Background technique [0002] Conventionally, fixed gas fire extinguishing devices have been used for fires that occur in closed spaces such as engine rooms and cargo spaces of ships. As the fire extinguishing agent of the fixed gas fire extinguishing device, non-reactive gases such as halon (including halon substitutes) and / or carbon dioxide can be used. [0003] Halon is a fire extinguishing agent that achieves the purpose of extinguishing a fire through a cooling effect and chemical action, but since the fire extinguishing agent itself is decomposed by heat generated by a fire to generate acid gases such as hydrogen fluoride, it is problematic from an environmental point of view. In addition, since an inert gas such as carbon dioxide extinguishes a fire by reducing the oxygen concentration in the room, it cannot be used when a person st...
