Description

Technical Field

[0001] The invention belongs to the technical field of fire extinguishing, and in particular relates to a multifunctional fire extinguishing device for fire extinguishing and emergency handling. Background Art

[0002] Among various disasters, fire occurs most frequently and is one of the main disasters that threaten personal safety and social development. When a fire occurs, by taking reasonable measures to deal with the fire, the spread of the fire can be controlled in time, thereby avoiding the occurrence of larger-scale fires and minimizing the losses caused by the fire. There are usually several ways to extinguish the fire.

[0003] Water mist fire extinguishing mainly uses water as the extinguishing medium, using a high-pressure water pump and a specially designed nozzle to disperse the water flow into fine droplets. The evaporation of the water mist causes efficient cooling and oxygen-deficient suffocation, which can achieve the effect of extinguishing the fire. The application of water mist fire extinguishing technology is basically not limited by the fire scene, and can be used to deal with fires of solid, oil and gas fuels.

[0004] Chemical inhibitor fire extinguishing is a method of suppressing fire by chemical means and ultimately achieving the purpose of extinguishing fire. Its core principle is to use chemical inhibitors to react with free radicals generated during the combustion process, thereby interrupting the combustion chain reaction and preventing the spread of fire and the combustion process.

[0005] Metastable active water fire extinguishing, active water (also called temperature active water) is a steam-water droplet mixture, which is obtained by the instantaneous transformation of insufficiently heated water to boiling water (within 10^-9^ to 10^-4^ seconds). Due to high pressure, the water does not boil, and enters a metastable state and subsequent explosive boiling. Active water droplets are in a metastable state, and different physical and chemical properties will occur from ordinary water, such as changes in oxidation recovery potential, viscosity and dielectric constant. This makes active water have good smoke precipitation characteristics or enhance the melting process of gas, and overall has certain advantages in fire extinguishing efficiency and environmental protection.

[0006] However, the use of a large number of existing technical equipment in firefighting equipment (firefighting and rescue) is low-power and inefficient, and cannot meet the actual needs for diversity in specific fire extinguishing methods.
