Problems solved by technology

Therefore it cannot be applied to outdoor fires
In addition, most fires occur at the bottom of the space. For a fire in a large-volume space with a high roof, it is difficult to quickly extinguish the fire because a large amount of nitrogen-enriched air must be injected to fill the entire space.
[0007] Carbon dioxide gas is heavier than air, and can stay in roofless buildings and outdoor low-lying areas; in addition, carbon dioxide can maintain a liquid state at room temperature through pressurization, so it is convenient for storage and transportation. In addition to being used as a fixed fire extinguishing equipment, It is also used as a mobile fire extinguishing equipment for pit fire extinguishing, but because the concentration required to extinguish general combustibles is about three times the concentration that is dangerous to human life, it cannot be used in places with people

Embodiment Construction

[0026] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the embodiments.

[0027] Figure 1 shows an embodiment of the present invention. The fire extinguishing system consists of a gas-liquid mixing and rectifying device 2, an ultrasonic water particle generator 3, a nitrogen-enriched air generating device 4, an air compressor 5, a water storage container 6, and pipelines. It can be quickly transported to the fire scene by vehicles or large helicopters.

[0028] When a fire breaks out in the high-roofed and large-capacity warehouse 1 shown in the figure, this system equipped with the fire brigade moves quickly to the scene. According to whether there are people in the fire space, the scale of the fire, the type of combustibles and the condition of the building, use the nitrogen-enriched air generator 4 to produce nitrogen-enriched air with the required oxygen concentra...

Abstract

A fire extinguishing method by use of gas-liquid mixture features that the N2-enriched air is mixed with the solution whose primary component is water to obtain the mixture whose specific weight is higher than that of air, and the mixture is used to cover on fire flame for extinguishing it. Its apparatus is composed of gas-liquid mixing and straightening unit, ultrasonic water particle generator, N2-enriched air generator, air compressor, water storage container and pipeline.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a fire extinguishing method and fire extinguishing equipment using nitrogen-enriched air-water particle groups and nitrogen-enriched air-foam groups. Background technique [0002] Fire extinguishing with water is the main fire extinguishing method used by existing mobile fire extinguishing equipment. Because water has a good cooling effect, is easy to supply, is cheap, non-toxic and does not pollute the environment, it has been the most commonly used fire extinguishing agent since ancient times. However, water as a liquid always settles under the influence of gravity. Unless the burning material is submerged, it cannot mix with the surrounding air like a gas fire extinguishing agent to cover the entire burning material to extinguish the fire. Therefore, when extinguishing a fire with water, the water discharge device must be close to the combustibles, and there must be no obstacl...
