What on earth is Aerosol fire extinguishing
What's aerosol fireplace extinguisher? Aerosol hearth extinguishing technological know-how is a completely new form of fire extinguishing technologies made on The idea of military pyrotechnics.
The 1st generation of aerosol fireplace extinguishing technological innovation was born in our place, also referred to as smoke fireplace extinguishing technologies, which commenced inside the early nineteen sixties. It was concluded by scientific researchers from your Tianjin Fireplace Study Institute of General public Protection, who independently developed an automated smoke hearth extinguishing technique, which is mainly used to extinguish fires in school A, B, and C liquid storage tanks.
Inside the early nineteen eighties, Using the emergence of environmental defense problems of “halon fire extinguishing agent”, obtaining alternatives to halon became a vital exploration topic.
At the end of the 1980s, Russian scientists 1st succeeded in investigating aerosol fireplace extinguishing engineering that could extinguish fires inside of a submerged fashion, which opened up a new way for halon substitution analysis. Subsequently, aerosol hearth extinguishing technological innovation has captivated the eye of the Worldwide Local community, and countries including China, The us, Australia, Malaysia and also other international locations have also started investigation on new aerosol hearth extinguishing technologies.
In most cases, aerosol is actually a stable state system formed by the dispersion of fine solid or liquid particles inside of a fuel. Skillfully, it refers to some colloidal method that utilizes fuel (commonly air) as being the dispersion medium and reliable or liquid particles because the dispersant.Typical aerosols in mother nature—clouds, smoke, fog, and many others.The dimensions of the particles in aerosols is generally while in the purchase of ten-5 to 10-oneμm, that has gas fluidity and will diffuse all over hurdles.
The medicament in the aerosol fireplace suppression technique system is sound, and the ingredient emitted with the medicament from the oxidation-reduction reaction is aerosol. The main generation of aerosol hearth extinguishing technological innovation-smoke fire extinguishing know-how.
K-variety aerosol fireplace extinguisher, also referred to as potassium salt fireplace extinguishing technological innovation, is the 2nd stage of the event of aerosol fire extinguishing technological know-how, which started in the previous Soviet Union inside the mid-sixties. Our nation started off late Within this regard, setting up within the early nineties.
In such a aerosol building agent, potassium nitrate is principally used as the principle oxidant. Its sprays have higher hearth extinguishing performance, but because they have a great deal of potassium ions, Quick to absorb moisture, forming a yellow and sticky sturdy alkaline conductive liquid movie, this compound is very damaging to electronic products, so K-form aerosol computerized fireplace extinguishing gadget can not be Utilized in electronic products, precision devices and cultural relics Archive put. At present, the use out there is progressively reducing.
The third-era aerosol (S variety) is principally crafted from strontium salt as the main oxidant. In contrast to the second-generation potassium salt (K-type) aerosol, strontium ions tend not to soak up dampness, usually do not kind a conductive Remedy, and will never lead to damage to electrical tools. In 2001, China Mobile Communications Corporation picked the strontium salt aerosol (S-type aerosol computerized hearth extinguishing product) made by the business right after rigid inspection and verification to guard its communication foundation stations together with other spots Outfitted with advanced Digital devices.
At the moment, strontium salt aerosol goods have been used in 1000s of engineering tasks, and the 3rd-generation aerosol has become more and more recognized by consumers
Aerosol fire extinguisher software assortment
a. Electrical fireplace
Interaction space, interaction base station, Digital computer home, and many others.;
Electrical fires in areas made up of precision instruments and equipment, for example energy distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, etcetera.
b. Sound area fire
Floor fire of combustible reliable materials in destinations in which combustible stable supplies are applied or stored.
c. Liquid hearth
Liquid fires in destinations exactly where diesel oil is generated, used or stored (other than -35 diesel), hefty oil, transformer oil, animal and vegetable oil and also other flammable liquids of Category C; In advance of extinguishing a gasoline fire, the gasoline resource could be Minimize off.
Aerosol fireplace suppression system application .
d. The S-type aerosol fire extinguishing device cannot be accustomed to set out the following fires
1. Substances that can be oxidized without having air, such as nitrocellulose, gunpowder, and many others.; active metals, including potassium, sodium, magnesium, titanium, and so forth.; compounds which will decompose by them selves, such as particular peroxides, hydrazine, and many others. Steel hydrides, for instance potassium fluoride, sodium hydride, etcetera. Normal substances, which include phosphorus. Powerful oxidants, which include nitrogen oxide, fluorine, and many others.
2. Deep fireplace of combustible reliable supplies.
3. Fireplace in crowded locations, such as theaters, auditoriums, etc.
4. Hearth in locations with explosion hazard, which include workshops with explosive dust.
5. Ultra-clean up natural environment, such as pharmaceutical workshops, chip processing areas, healthcare rooms, etcetera.
Aerosol fire extinguishing Doing the job principle
The four things of combustion: combustibles, oxidizer, temperature and uninhibited chain reaction. The fireplace extinguishing system of fireplace extinguishing gas is usually to eliminate a single or quite a few from the four features of combustion.
The strong fire extinguishing agent from the S-type aerosol fire extinguishing system is begun by electricity, and it undergoes redox reaction to kind a lot of agglomerated hearth extinguishing aerosols, and its composition is principally N2, a little volume of CO2, and metallic salt good particles.
Aerosol fireplace extinguishing system is as follows
System of endothermic cooling and fireplace extinguishing
Steel salt particles take in a large amount of heat at large temperatures, and go through Bodily endothermic processes like thermal melting and gasification. The flame temperature is lowered then radiated on the combustible combustion surface area for gasification of combustible molecules and vaporized combustible molecules. The heat of pyrolysis of combustion molecules into free of charge radicals will reduce, as well as the combustion reaction speed will be suppressed to a specific extent.
