Carbon dioxide fire extinguisher Portable carbon dioxide fire extinguisher

Carbon dioxide fire extinguisher Portable carbon dioxide fire extinguisher fire extinguisher is driven by its own vapor pressure of stored pressure fire extinguishers, there are two forms of portable and wheeled. Portable carbon dioxide fire firearm total weight does not exceed 28Kg, hand movement by the operator during use. The total weight of carbon dioxide exceeded Trolley 60kg, when using the pulling or pushing movement by the operator. Carbon dioxide fire extinguisher Specifications: Portable: MT / 2; MT / 3; MT / 5 Trolley: MTT / 24; The main performance parameters of the project type extinguishing agents kg weight carbon dioxide fire extinguisher effective injection time s effective spray jet lag time distance m s The remaining rate% level jet fire temperature range ℃ Dimensions diameter × height mm MT / 2 20-0.10 ≥8 ≥2 ≤5 ≤10 21B -10 ~ + 55 116 × 485 MT / 3 30-0.15 ≥8 ≥2 When ≤5 ≤10 21B -10 ~ + 55 116 × 640 MT / 5 50-0.25 ≥8 ≥2.5 ≤5 ≤10 34B -10 ~ + 55 136 × 755 using a carbon dioxide fire extinguisher use of carbon dioxide, along with pressure reduction The carbon dioxide fire extinguisher seal open, liquid carbon dioxide under the effect of its vapor pressure, and the injector is connected via a siphon tube from the nozzle. Due to the sudden decrease in pressure, rapid vaporization of liquid carbon dioxide, but the heat of vaporization needed in short supply, liquid carbon dioxide absorbed by itself when the heat of vaporization have the results part of the carbon dioxide condenses into solid snow, the temperature dropped to -78.5 ℃. Therefore, the discharge from the fire extinguisher is a mixture of carbon dioxide gas and solids. When carbon dioxide is coated on the snow-like combustion instantly vaporized (sublimated), combustion exhibit certain cooling effect. However, when the cooling effect of carbon dioxide fire extinguisher is unlikely, it mainly depends on the principle of dilution air to the combustion zone of the oxygen concentration in the air to maintain the limit oxygen concentration falls below the burning material so that the burning of suffocation. Use Portable carbon dioxide fire extinguisher should note the following: (1) fire extinguisher in the injection process should be kept upright state, must not use flat or inverted; (2) when not wearing protective gloves, do not hand hold direct Pentong or metal pipe; prevent frostbite; (3) should be used in selecting outdoor spray upwind direction. (4) When a small indoor space usage, should be quickly evacuated after the fire, to prevent accidents by carbon dioxide asphyxiation; (5) after fighting with a carbon dioxide fire indoors, you should ventilate, then ran into the people, to prevent suffocation.
