Precisely what is Aerosol fireplace extinguishing What exactly is aerosol fire extinguisher? Aerosol fireplace extinguishing technological innovation is a new type of fire extinguishing technological innovation developed on The idea of armed forces pyrotechnics.

The very first era of aerosol fire extinguishing know-how was born inside our place, also called smoke fire extinguishing technological innovation, which began during the early sixties. It absolutely was completed by scientific scientists in the Tianjin Hearth Exploration Institute of Community Stability, who independently designed an computerized smoke fireplace extinguishing technique, which is especially accustomed to extinguish fires at school A, B, and C liquid storage tanks. While in the early nineteen eighties, with the emergence of environmental protection complications of “halon fireplace extinguishing agent”, finding solutions to halon became a vital study subject. At the end of the eighties, Russian researchers initially succeeded in studying aerosol fireplace extinguishing technological innovation which will extinguish fires inside of a submerged way, which opened up a different way for halon substitution research. Subsequently, aerosol hearth extinguishing technologies has captivated the eye from the Intercontinental Local community, and countries including China, the United States, Australia, Malaysia along with other countries have also begun exploration on new aerosol fire extinguishing systems. In most cases, aerosol is a secure state process formed from the dispersion of high-quality sound or liquid particles inside of a gas. Skillfully, it refers to some colloidal system that employs gas (ordinarily air) as the dispersion medium and reliable or liquid particles as being the dispersant.Popular aerosols in nature—clouds, smoke, fog, and so on.The size of the particles in aerosols is mostly within the buy of ten-5 to 10-oneμm, that has fuel fluidity and may diffuse close to hurdles. The medicament in the aerosol fireplace suppression procedure gadget is strong, plus the component emitted because of the medicament with the oxidation-reduction response is aerosol. The first technology of aerosol hearth extinguishing technologies-smoke hearth extinguishing engineering. K-form aerosol fire extinguisher, also called potassium salt fireplace extinguishing technological innovation, is the 2nd phase of the event of aerosol fire extinguishing technology, which started in the former Soviet Union in the mid-sixties. Our nation commenced late in this regard, beginning from the early 1990s. In this type of aerosol generating agent, potassium nitrate is principally used as the key oxidant. Its sprays have higher fireplace extinguishing effectiveness, but given that they have a great deal of potassium ions, Easy to soak up humidity, forming a yellow and sticky strong alkaline conductive liquid film, this material may be very harmful to electronic devices, so K-type aerosol automated fire extinguishing product cannot be used in electronic tools, precision instruments and cultural relics Archive put. At present, the use available in the market is little by little lowering. The 3rd-technology aerosol (S sort) is especially manufactured from strontium salt as the most crucial oxidant. In contrast to the next-generation potassium salt (K-kind) aerosol, strontium ions never take up humidity, will not sort a conductive Alternative, and is not going to trigger harm to electrical equipment. In 2001, China Mobile Communications Company selected the strontium salt aerosol (S-form aerosol automatic hearth extinguishing unit) made by the company after rigorous inspection and verification to safeguard its interaction base stations along with other destinations Geared up with refined Digital tools. At the moment, strontium salt aerosol products and solutions have already been used in Many engineering projects, and the 3rd-technology aerosol has grown to be Increasingly more recognized by users Aerosol fire extinguisher application assortment a. Electrical fire Interaction place, interaction base station, Digital Laptop area, etcetera.; Electrical fires in destinations containing precision instruments and gear, including electricity distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, and so on. b. Sound surface fire Floor fireplace of combustible strong resources in sites the place combustible reliable components are applied or saved. c. Liquid fireplace Liquid fires in places in which diesel oil is developed, utilized or stored (besides -35 diesel), hefty oil, transformer oil, animal and vegetable oil and other flammable liquids of Classification C; In advance of extinguishing a fuel fire, the fuel resource might be Minimize off. Aerosol fire suppression program software . d. The S-variety aerosol hearth extinguishing gadget can't be accustomed to set out the following fires ①Substances that could be oxidized with out air, which include nitrocellulose, gunpowder, and many others.; active metals, for instance potassium, sodium, magnesium, titanium, etcetera.; compounds that may decompose by themselves, including sure peroxides, hydrazine, and so forth. Steel hydrides, for instance potassium fluoride, sodium hydride, and so forth. Normal substances, for instance phosphorus. Powerful oxidants, including nitrogen oxide, fluorine, and many others. ② Deep fire of combustible stable components. ③ Fire in crowded areas, such as theaters, auditoriums, etc. ④ Fire in spots with explosion hazard, including workshops with explosive dust. ⑤ Ultra-thoroughly clean surroundings, such as pharmaceutical workshops, chip processing spots, health care rooms, etcetera. Aerosol fireplace extinguishing Doing work theory The four things of combustion: combustibles, oxidizer, temperature and uninhibited chain response. The fire extinguishing system of fire extinguishing gasoline is usually to eliminate one or numerous in the four aspects of combustion. The reliable fire extinguishing agent in the S-variety aerosol hearth extinguishing gadget is started out by electric power, and it undergoes redox reaction to type a large number of agglomerated fire extinguishing aerosols, and its composition is mainly N2, a small quantity of CO2, and steel salt solid particles. Aerosol hearth extinguishing mechanism is as follows System of endothermic cooling and fireplace extinguishing Metallic salt particles absorb a great deal of warmth at large temperatures, and undertake physical endothermic procedures for instance thermal melting and gasification. The flame temperature is reduced and afterwards radiated to the combustible combustion floor for gasification of combustible molecules and vaporized combustible molecules. The heat of pyrolysis of combustion molecules into cost-free radicals will reduce, and also the combustion reaction velocity might be suppressed to a specific extent.
