Exactly what is Aerosol hearth extinguishing Exactly what is aerosol fireplace extinguisher? Aerosol fire extinguishing technology is a different kind of fireplace extinguishing technology developed on the basis of navy pyrotechnics.

The primary technology of aerosol hearth extinguishing engineering was born inside our country, also referred to as smoke hearth extinguishing know-how, which started while in the early 1960s. It had been concluded by scientific researchers in the Tianjin Hearth Study Institute of Community Protection, who independently produced an computerized smoke hearth extinguishing system, which is especially used to extinguish fires in Class A, B, and C liquid storage tanks. During the early eighties, Using the emergence of environmental protection complications of “halon hearth extinguishing agent”, finding possibilities to halon became a vital research matter. At the end of the nineteen eighties, Russian scientists 1st succeeded in investigating aerosol hearth extinguishing engineering which will extinguish fires inside of a submerged method, which opened up a new way for halon substitution exploration. Subsequently, aerosol fireplace extinguishing technological know-how has attracted the attention with the international Neighborhood, and countries which include China, America, Australia, Malaysia as well as other nations around the world have also started investigation on new aerosol hearth extinguishing systems. Most of the time, aerosol is actually a stable condition process fashioned with the dispersion of wonderful good or liquid particles inside a gasoline. Professionally, it refers to your colloidal process that makes use of fuel (commonly air) as the dispersion medium and strong or liquid particles given that the dispersant.Frequent aerosols in character—clouds, smoke, fog, and so forth.The dimensions of the particles in aerosols is usually while in the buy of ten-5 to 10-1μm, that has gasoline fluidity and might diffuse all-around obstacles. The medicament during the aerosol hearth suppression program system is good, as well as the part emitted through the medicament with the oxidation-reduction response is aerosol. The main generation of aerosol fireplace extinguishing technologies-smoke fireplace extinguishing technologies. K-type aerosol fireplace extinguisher, also called potassium salt hearth extinguishing technological innovation, is the second stage of the development of aerosol fireplace extinguishing know-how, which commenced in the former Soviet Union inside the mid-nineteen sixties. Our place began late Within this regard, commencing within the early nineteen nineties. In this kind of aerosol producing agent, potassium nitrate is principally made use of as the leading oxidant. Its sprays have higher hearth extinguishing efficiency, but mainly because they comprise a great deal of potassium ions, Quick to soak up dampness, forming a yellow and sticky sturdy alkaline conductive liquid movie, this material is rather harming to electronic machines, so K-sort aerosol automatic fire extinguishing system can't be Utilized in Digital gear, precision instruments and cultural relics Archive location. At the moment, the use on the market is progressively lowering. The third-era aerosol (S style) is especially made of strontium salt as the main oxidant. Compared with the next-generation potassium salt (K-style) aerosol, strontium ions will not absorb dampness, tend not to type a conductive Answer, and will likely not induce harm to electrical gear. In 2001, China Mobile Communications Corporation picked the strontium salt aerosol (S-form aerosol automatic fire extinguishing gadget) made by the organization right after rigid inspection and verification to shield its interaction base stations along with other locations Geared up with innovative Digital tools. At the moment, strontium salt aerosol solutions are already used in 1000s of engineering tasks, and the third-era aerosol has grown to be more and more recognized by customers Aerosol fire extinguisher application assortment a. Electrical fireplace Conversation place, communication base station, Digital Laptop or computer room, and so on.; Electrical fires in places made up of precision instruments and tools, for example energy distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, and so forth. b. Stable floor fire Area hearth of combustible good supplies in destinations wherever combustible solid elements are utilized or stored. c. Liquid fire Liquid fires in sites where diesel oil is manufactured, utilized or stored (except -35 diesel), significant oil, transformer oil, animal and vegetable oil and other flammable liquids of Group C; Just before extinguishing a gasoline hearth, the fuel resource may be cut off. Aerosol fireplace suppression process application . d. The S-type aerosol fireplace extinguishing product can't be utilized to put out the following fires ①Substances which might be oxidized with no air, for example nitrocellulose, gunpowder, and so on.; Energetic metals, for example potassium, sodium, magnesium, titanium, etc.; compounds which can decompose by by themselves, such as specified peroxides, hydrazine, etcetera. Steel hydrides, such as potassium fluoride, sodium hydride, and so on. Purely natural substances, for instance phosphorus. Sturdy oxidants, which include nitrogen oxide, fluorine, and so forth. ② Deep hearth of combustible stable components. ③ Fire in crowded locations, for example theaters, auditoriums, and many others. ④ Fire in locations with explosion hazard, like workshops with explosive dust. ⑤ Ultra-clear ecosystem, for instance pharmaceutical workshops, chip processing destinations, health care rooms, and so on. Aerosol hearth extinguishing Performing theory The 4 things of combustion: combustibles, oxidizer, temperature and uninhibited chain response. The hearth extinguishing system of fireplace extinguishing fuel should be to do away with one particular or various in the 4 aspects of combustion. The sound fireplace extinguishing agent from the S-form aerosol hearth extinguishing device is commenced by electrical power, and it undergoes redox reaction to variety a large number of agglomerated hearth extinguishing aerosols, and its composition is especially N2, a small volume of CO2, and metallic salt sound particles. Aerosol hearth extinguishing mechanism is as follows System of endothermic cooling and hearth extinguishing Metal salt particles take in a large amount of warmth at high temperatures, and undergo Bodily endothermic procedures including thermal melting and gasification. The flame temperature is reduced after which radiated towards the combustible combustion floor for gasification of combustible molecules and vaporized combustible molecules. The warmth of pyrolysis of combustion molecules into totally free radicals will reduce, as well as combustion reaction speed is going to be suppressed to a specific extent.
