The beneficial effects of the utility model:
Water mists go out control fire mechanism include: cooling, suffocate, cut off heat radiation.Owing to water mists is made up of the water smoke that diameter is the least, how with relative with as the water of volume, the surface area of water mists is very big, has the strongest heat-exchange capacity, the temperature in the scene of a fire can be made to decline rapidly, destroy the temperature conditions of flame combustion.While fire extinguishing, tiny water droplet absorbs substantial amounts of heat rapid vaporization so that it is volumetric expansion can reach more than 1700 times of original volume, thus reduces the oxygen concentration near burning things which may cause a fire disaster, prevent the oxidation reaction condition of flame combustion, serve the effect suffocated.On this burning things which may cause a fire disaster only occurring in high temperature that suffocates, outside burning things which may cause a fire disaster, the oxygen concentration of human peripheral will not reduce, and thus without generation, personnel suffocate.
Water mists in cooling, suffocating and completely cutting off thermal-radiating triple role is issued to go out the effect of control fire, it has water smoke and the dual function of extinction using gas and advantage during the control fire that goes out, the cooling effect of existing water mist sprinkling system, there is again the smothering action of gas extinguishing system, so going out, control fire efficiency is high, good reliability, and do not pollute.
Relative to the medicament fire extinguishing to the greatest extent of heptafluoro-propane and cigarette Lip river, water mists go out control fire system due to most commonly seen water as extinguishing chemical, have a following major advantage:
1. water for fire extinguishing take conveniently, cheap, generally, 1 critical water amount for fire suppression about 0.6～1.5m3, and other gas extinguishing agent needs the production of specialized factory, buying, expensive.Water mist system is after fire extinguishing, if it occur that fire can reuse repeatedly at once, and medicament is previously stored in low capacity steel cylinder, needs to refill after fire extinguishing, is difficult to the most again come into operation.
2. the impact in terms of environmental conservation is compared.Heptafluoro-propane is Halon substitute, and the analyte produced in fire extinguishing procedure is faintly acid gas, is discharged in air and can cause environmental effect, produces greenhouse effect.Water Mist Fire Extinguishing Technique is with water as extinguishing chemical, harmless to human non-toxic and do not have pollutant emission, safety and environmental protection to environment.The most also there is toxic component and the function of depositing dust, beneficially personnel escape in cleaning smog.
Therefore, water mist system is relative to gas extinguishing system, and the environmental requirement of use is lower, safeguards convenient, and the requirement to attendant is the lowest, and greatly reduces equipment cost, has the highest promotional value.
