According to the method of producing aerosols, they can be divided into hot aerosols and cold aerosols fire extinguishing devices.
At present, the aerosol fire extinguishing devices used in domestic engineering belong to the thermal type, and the cold aerosol fire extinguishing technology is still in the research and development stage, with no formal products available. Thermal aerosols extinguish fires based on principles such as negative catalysis and disruption of combustion reaction chains.
Thermal aerosol belongs to a fully submerged system, which gradually extinguishes the fire while controlling the source of the fire, allowing sufficient time for personnel to evacuate and escape. It is suitable for unmanned, relatively enclosed, and small space places such as transformer and distribution rooms, generator rooms, cable interlayers, cable wells, and cable trenches.
In recent years, aerosol fire extinguisher devices have been continuously improved and can now be used as commonly used fire extinguishers in automobiles.
There is currently a new type of portable aerosol fire extinguisher that can be used for both home and car purposes on the market. Combining the advantages of various fire extinguishers, it not only has a small size but also has extremely strong fire extinguishing ability. After extinguishing the fire, there will be no harmful substances left, and it has been widely used in military and police applications.
The principle is to use hot aerosol and nano dry powder to jointly generate nano particle fire extinguishing agent. This fire extinguishing agent can absorb heat and decompose the chemical reaction with the burning substance, reducing the temperature of the ignition object, preventing the flame from continuing to spread, and terminating the combustion.
Although the volume of this aerosol fire extinguisher is only the size of a bottle of mineral water and weighs only 470g, its fire extinguishing capacity is equivalent to that of a 3kg dry powder fire extinguisher.
once! Only once! Regardless of whether you have used it or not, as long as you have used it, you must go to a designated fire extinguisher repair point or fire extinguisher manufacturer to replenish the agent, otherwise the next time you use it, the fire extinguishing effect will not be achieved.
Aerosol fire extinguishers use certain chemical and physical methods to spray the fire extinguishing agent in the form of aerosols to extinguish the fire. The fire extinguishing principle of aerosol fire extinguishers is that the solid fire extinguishing particles filled inside decompose into a large amount of efficient fire extinguishing substances through the interaction of potassium salt gas producing agents.
Just like when we wash our hands with soap, the solid fire extinguishing particle generator is soap, and our hands are like gas producing agents. Only under the interaction of fingers and soap can soap foam be produced to achieve the purpose of cleaning. The aerosol extinguishing material produced by the aerosol extinguisher under the interaction of extinguishing agent and gas generating agent is equivalent to "soap foam" used to deal with fire.
