Exactly what is Aerosol fireplace extinguishing What on earth is aerosol fire extinguisher? Aerosol fire extinguishing technological know-how is a new kind of fire extinguishing know-how created on The premise of navy pyrotechnics. The first generation of aerosol hearth extinguishing technological know-how was born in our nation, generally known as smoke fire extinguishing technological know-how, which began while in the early 1960s. It had been done by scientific researchers from your Tianjin Hearth Study Institute of Community Protection, who independently developed an computerized smoke hearth extinguishing procedure, which is principally used to extinguish fires at school A, B, and C liquid storage tanks.

While in the early eighties, While using the emergence of environmental protection issues of “halon fire extinguishing agent”, acquiring options to halon became an important investigation subject matter. At the end of the eighties, Russian experts to start with succeeded in studying aerosol hearth extinguishing engineering that can extinguish fires in a very submerged way, which opened up a new way for halon substitution study. Subsequently, aerosol fireplace extinguishing know-how has attracted the eye from the Intercontinental Neighborhood, and nations such as China, The usa, Australia, Malaysia and also other nations around the world have also started investigate on new aerosol fire extinguishing systems. Generally speaking, aerosol is actually a steady point out program formed from the dispersion of wonderful good or liquid particles in the gas. Skillfully, it refers to your colloidal process that employs gasoline (commonly air) given that the dispersion medium and stable or liquid particles since the dispersant.Common aerosols in nature—clouds, smoke, fog, and so on.The scale of your particles in aerosols is usually within the order of ten-5 to 10-1μm, that has gasoline fluidity and might diffuse all around obstructions. The medicament during the aerosol fire suppression method machine is stable, plus the part emitted by the medicament in the oxidation-reduction reaction is aerosol. The first generation of aerosol fire extinguishing technological innovation-smoke fireplace extinguishing technologies. K-sort aerosol fireplace extinguisher, also known as potassium salt fireplace extinguishing know-how, is the second phase of the event of aerosol fire extinguishing technology, which started in the previous Soviet Union while in the mid-sixties. Our state started off late In this particular regard, starting up in the early nineties. In such a aerosol generating agent, potassium nitrate is principally used as the key oxidant. Its sprays have large hearth extinguishing performance, but as they incorporate a great deal of potassium ions, Easy to soak up moisture, forming a yellow and sticky powerful alkaline conductive liquid movie, this compound is rather damaging to electronic products, so K-style aerosol automated fireplace extinguishing gadget can't be used in electronic machines, precision devices and cultural relics Archive location. At present, the use available in the market is gradually decreasing. The third-era aerosol (S sort) is principally manufactured from strontium salt as the main oxidant. Not like the second-era potassium salt (K-type) aerosol, strontium ions do not take up moisture, will not kind a conductive Remedy, and will never lead to damage to electrical tools. In 2001, China Mobile Communications Company picked the strontium salt aerosol (S-variety aerosol automatic hearth extinguishing system) produced by the organization following demanding inspection and verification to shield its interaction base stations and other places Outfitted with refined electronic tools. At this time, strontium salt aerosol products happen to be used in Many engineering tasks, as well as the third-technology aerosol happens to be An increasing number of approved by buyers Aerosol fire extinguisher software vary a. Electrical fireplace Conversation space, communication base station, Digital Laptop or computer area, etcetera.; Electrical fires in locations made up of precision devices and tools, for instance electrical power distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, and many others. b. Sound floor hearth Area fire of combustible strong supplies in locations where by combustible solid materials are utilised or stored. c. Liquid hearth Liquid fires in destinations exactly where diesel oil is generated, utilised or saved (besides -35 diesel), weighty oil, transformer oil, animal and vegetable oil and various flammable liquids of Classification C; Prior to extinguishing a fuel hearth, the gas resource can be cut off. Aerosol fireplace suppression procedure software . d. The S-sort aerosol hearth extinguishing unit cannot be accustomed to set out the subsequent fires ①Substances that may be oxidized without having air, for example nitrocellulose, gunpowder, etcetera.; Energetic metals, for example potassium, sodium, magnesium, titanium, and so forth.; compounds which can decompose by them selves, which include certain peroxides, hydrazine, etcetera. Steel hydrides, like potassium fluoride, sodium hydride, and many others. Purely natural substances, including phosphorus. Robust oxidants, which include nitrogen oxide, fluorine, etcetera. ② Deep fire of combustible sound materials. ③ Hearth in crowded sites, such as theaters, auditoriums, and so forth. ④ Hearth in spots with explosion hazard, including workshops with explosive dust. ⑤ Extremely-clean ecosystem, including pharmaceutical workshops, chip processing areas, healthcare rooms, and so forth. Aerosol fireplace extinguishing working principle The 4 factors of combustion: combustibles, oxidizer, temperature and uninhibited chain response. The fireplace extinguishing mechanism of fireplace extinguishing gas would be to reduce a single or quite a few of your four elements of combustion. The reliable hearth extinguishing agent while in the S-variety aerosol hearth extinguishing gadget is begun by electrical energy, and it undergoes redox response to type a lot of agglomerated fire extinguishing aerosols, and its composition is mainly N2, a little level of CO2, and steel salt reliable particles. Aerosol fire extinguishing system is as follows Mechanism of endothermic cooling and fire extinguishing Metallic salt particles take in a great deal of heat at higher temperatures, and undergo Actual physical endothermic processes which include thermal melting and gasification. The flame temperature is lowered and then radiated to your combustible combustion floor for gasification of combustible molecules and vaporized combustible molecules. The warmth of pyrolysis of combustion molecules into cost-free radicals will reduce, along with the combustion reaction velocity is going to be suppressed to a specific extent.
