Details You Should Be Aware Of Aerosol Fire Extinguishing
What is Aerosol fire extinguishing Exactly what is aerosol fire extinguisher? Aerosol fire extinguishing technological innovation is a fresh style of fireplace extinguishing technology formulated on the basis of military services pyrotechnics. The 1st era of aerosol fire extinguishing technologies was born in our nation, also called smoke hearth extinguishing know-how, which began within the early 1960s. It absolutely was done by scientific researchers in the Tianjin Fireplace Analysis Institute of Public Protection, who independently produced an computerized smoke fire extinguishing method, which is principally used to extinguish fires in school A, B, and C liquid storage tanks.
From the early 1980s, Together with the emergence of environmental security troubles of “halon hearth extinguishing agent”, getting alternate options to halon turned a significant exploration subject. At the end of the 1980s, Russian experts to start with succeeded in looking into aerosol hearth extinguishing technology that may extinguish fires in a very submerged fashion, which opened up a new way for halon substitution research. Subsequently, aerosol hearth extinguishing know-how has attracted the attention on the Worldwide community, and nations around the world such as China, The usa, Australia, Malaysia along with other nations have also begun exploration on new aerosol hearth extinguishing systems. Most of the time, aerosol is actually a stable state procedure shaped via the dispersion of fine solid or liquid particles within a gasoline. Professionally, it refers to some colloidal method that employs fuel (usually air) as the dispersion medium and stable or liquid particles because the dispersant.Popular aerosols in mother nature—clouds, smoke, fog, etc.The dimensions from the particles in aerosols is mostly while in the order of 10-five to 10-1μm, which has gas fluidity and can diffuse about hurdles. The medicament from the aerosol hearth suppression process machine is strong, as well as ingredient emitted by the medicament through the oxidation-reduction response is aerosol. The primary technology of aerosol fireplace extinguishing engineering-smoke hearth extinguishing technological know-how. K-kind aerosol hearth extinguisher, also known as potassium salt fireplace extinguishing know-how, is the second phase of the event of aerosol fire extinguishing technology, which commenced in the previous Soviet Union inside the mid-1960s. Our country started late In this particular regard, starting up inside the early nineties. In this kind of aerosol generating agent, potassium nitrate is principally utilized as the key oxidant. Its sprays have superior fireplace extinguishing efficiency, but simply because they consist of a great deal of potassium ions, Effortless to soak up dampness, forming a yellow and sticky sturdy alkaline conductive liquid movie, this material is quite harmful to Digital products, so K-style aerosol computerized fireplace extinguishing machine cannot be Utilized in electronic products, precision instruments and cultural relics Archive put. At this time, the use available in the market is slowly decreasing. The third-era aerosol (S variety) is especially fabricated from strontium salt as the leading oxidant. As opposed to the second-era potassium salt (K-sort) aerosol, strontium ions usually do not absorb dampness, don't type a conductive Alternative, and will not likely result in damage to electrical devices. In 2001, China Cellular Communications Corporation selected the strontium salt aerosol (S-style aerosol automated fire extinguishing unit) made by the business soon after stringent inspection and verification to guard its interaction base stations along with other destinations Outfitted with innovative Digital gear. At the moment, strontium salt aerosol products and solutions are actually utilized in Countless engineering projects, as well as the third-technology aerosol has become A lot more recognized by buyers Aerosol fire extinguisher application vary a. Electrical hearth Conversation place, conversation foundation station, Digital computer room, etcetera.; Electrical fires in sites made up of precision instruments and devices, which include electricity distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, etc. b. Reliable surface hearth Surface area fireplace of combustible strong elements in spots exactly where combustible strong products are employed or stored. c. Liquid fireplace Liquid fires in locations in which diesel oil is developed, made use of or saved (besides -35 diesel), weighty oil, transformer oil, animal and vegetable oil along with other flammable liquids of Category C; Ahead of extinguishing a gasoline fireplace, the gas supply is often Reduce off. Aerosol hearth suppression method application . d. The S-form aerosol fireplace extinguishing product can't be used to place out the subsequent fires ①Substances that could be oxidized with out air, like nitrocellulose, gunpowder, etcetera.; Energetic metals, which include potassium, sodium, magnesium, titanium, etc.; compounds that may decompose by them selves, such as certain peroxides, hydrazine, and so on. Metal hydrides, for example potassium fluoride, sodium hydride, and so on. Purely natural substances, including phosphorus. Solid oxidants, which include nitrogen oxide, fluorine, etc. ② Deep fire of combustible strong supplies. ③ Fire in crowded places, which include theaters, auditoriums, and so forth. ④ Fire in areas with explosion hazard, for example workshops with explosive dust. ⑤ Ultra-clean setting, which include pharmaceutical workshops, chip processing areas, medical rooms, etc. Aerosol fireplace extinguishing Functioning theory The four aspects of combustion: combustibles, oxidizer, temperature and uninhibited chain response. The fire extinguishing mechanism of fire extinguishing gas is to reduce 1 or several on the 4 factors of combustion. The solid fire extinguishing agent in the S-kind aerosol hearth extinguishing device is started by electric power, and it undergoes redox reaction to variety a lot of agglomerated fire extinguishing aerosols, and its composition is especially N2, a small degree of CO2, and metallic salt stable particles. Aerosol fireplace extinguishing system is as follows System of endothermic cooling and fireplace extinguishing Metallic salt particles take up a great deal of heat at high temperatures, and undergo physical endothermic processes including thermal melting and gasification. The flame temperature is decreased and after that radiated for the combustible combustion surface area for gasification of combustible molecules and vaporized combustible molecules. The heat of pyrolysis of combustion molecules into totally free radicals will reduce, plus the combustion reaction velocity will be suppressed to a certain extent.
