Bus plans Aerosol fire extinguishing system
the most advanced automatic fire extinguishing system.
the basis and standard implementation:
1. GB50116-98 specification for design of automatic fire alarm system;
2. The GB50263-97 "gas fire extinguishing system construction and acceptance standard";
3. GB50166-92 "fire automatic alarm system code for construction and acceptance.
4. GB50370-2005 specification for design of gas fire extinguishing system;
5. The design of the construction units to provide the data.
Third, technology solutions
1, fire extinguishing and detecting equipment selection
According to the engineering general situation, can use first small whirlwind series electric launch products in our company.
2, small whirlwind series product features
Small whirlwind series products are potassium type of S type extinguishing aerosol extinguishing agent products, won"t produce harm to protect the electrical equipment of potassium in the particles.
fire extinguishing agent produced by solid particles were very small, about 3% (and other similar aerosol products of solid particle content about 40%)
fire extinguishing agent produced by solid particle size is very small. These particles than closed within one month of the dust in the computer room natural land quantity is less, and these particles even in the condition of high temperature and wet 80% (relative), also have no electrical conductivity and corrosion resistance. Won"t produce any damage to electrical equipment. This is fundamental difference with other aerosol products.
fire extinguishing agent for solid state storage, omitted the high-pressure cylinders, valves and so on a large number of complex equipment, reduce the cost. No maintenance after installation, it is very simple and reliable.
Small whirly series of products the use of the new chemical coolant and composite technique of physical cooler, the gas within 120 seconds flameless release at low temperature.
Small whirly series products shell adopts 304 stainless steel shell, seal assembly. Suitable for use in some corrosive environment, their level of IP protection can be IP55.
3. The scope of
Can put out A, B, E all kinds of fire, can be used safely and effectively in some places;
reagent after discharge, request a Tube or cleaning residue is difficult places;
Lower reserve contains the valuables, precious files and software, etc.;
Suitable for buses, cable interlayer, computer room, library, archives, transformer room, telecommunications center, underground engineering and other places gas fire protection;
Low temperature difference is bigger, the corrosive environment.
4, the component of product:
Automatic aerosol fire extinguishing device by fire extinguishing installation, support, start the connectors, etc. Low assembly way (below) :
5, technical parameters
1. The work environment temperature: - 20 ℃ ~ + 55 ℃
2. Working environment relative humidity: 95% or less
3. The working pressure: the atmospheric pressure
4. Discharge time: 120 s or less
Temperature: 5. Nozzle aerosol ahead 5 mm at 200 ℃ or less
6. Products insulation performance: 20 m Ω or greater
7. Starting current: 1 a
7, construction installation and matters needing attention:
1, hot gas sol fire extinguishing device using stents ceiling installation.
2, aerosol spray mouth within 0.2 m, there can be no obstructions.
3, aerosol extinguishing equipment is strictly prohibited without authorization, remove.
4, extinguishing equipment after the discharge, if you want to immediately remove must Dai Gaowen gloves, prevent burns.
6. system composition and principle:
(1) automatic control mode
Each reserve installation at the scene point smoke and heat detectors, fire, smoke and heat detector alarm at the same time, the alarm signal transmission to the gas fire extinguishing control panel, if the gas extinguishing plate in the automatic state, will directly start small whirlwind spewed gas on-site fire fighting.
(2) the manual control mode
When there is a fire, if the failure or researchers found that fire automatic way, can be directly through the manual start small whirlwind fire, in order to jumpstart extinguishing small whirlwind, the scheme on the gas extinguishing plate and each protection zone were set up at the gate of start-stop buttons, convenient staff in a timely manner quickly press the start button, to reduce the loss of the fire.
