China manufacture water mist fire fighting system high pressure
High-pressure Microscopic Water Droplet Fire-Fighting Cart
Testing Certificate No.:Zb201650289
Operating Temperature Range:-20℃(anti-freezing solution)-55
Equipped with long-range and short-range spray guns. Large-capacity, high-energy and environmentally friendly lithium battery, 72V40AH, is adopted, which can last for 30 minutes on a single charge.
High pressure hose reel is designed automatically retracted, which is labor-saving and convenient. Large stainless steel tank, 180L, can last for 8 minutes.
Fire Mechanism of High Pressure Water Mist:
1. High-efficiency Heat Absorption: 100℃ water evaporation latent heat is 2257kJ/K. Every 1 Kg water mist sprayed out can absorb heat of 300kW. Its heat absorption rate is very high, and its cooling effect is very strong.
2. Suffocation: the water mist rapidly expands 1700-5800 times after vaporizing by heat. The water vapor covers the flaming material and keeps air out. Then the flaming material stops burning because of oxygen deficit.
3. Radiant heat barrier: vapor formed by water mist vaporization rapidly covers the flaming material, fire and smoke. It’s a strong barrier to the radiant heat, preventing the fire spreading.
4. Smoke and dust scrubber: high pressure water mist can scrub the smoke and exhaust gas, because the burning ashes, carbon granule and harmful gas combine with the water droplets. According to statistics, 70% fatal accidents among fire accidents are caused by high temperature smoke and harmful gas, not directly by fire.
5. Wetting effect: can put out the fire caused by oil. High pressure mist droplet moves very fast, so it can rapidly covers the surface of the flaming oil, then stops the generation of new combustible gases. Meanwhile, the mist droplet is so fine that it won’t stir the oil, causing sparks-fly, which stops the fire and prevent the fire spreading.
6. Three-dimensional movement: when the high pressure water mist is sprayed out, some of the small-diameter mist droplets move horizontally or move upwards, then enter the upper space of the spray nozzle, instead of moving forward along the spray direction. Therefore the water mist covers the whole protected area. The smaller diameter of the mist droplet is, the stronger horizontal movement is. This is called three-dimensional fire extinguishing.
7. High pressure water mist can put out electrical fire. (NFPA Specificaiton750)
8. Why the high pressure water mist is non-conductive when used for electrical fire The mist droplet’s diameter is small (10-100micron). It’s not discontinuous and can suspend in the air for a long time. It needs a substantial number of mist droplets and takes a very long time to realize the water mist convergence and condensation, so it’s difficult to form continuous water flow or waters on the surface of the electrode. Its electrical resistivity is a litter smaller than that of the air.
High pressure water mist fire-fighting product is applicable to A-type solids, B-type oils, C-type flammable gases, E-type electric equipment and F-type kitchen fires. Its advanced fire mechanism makes it not limited to places, usable in land, ocean and space. It’s especially effective for the protection of high-risk places, for example, tobacco, electric power, railway, school, community, petrochemical industry, military equipment, mining industry, pharmaceuticals industry, food processing industry, ancient buildings, archives, commercial and civil buildings, subway, large transport vehicles, ships, aerospace, electronics industry, fire brigade, forest police, etc. High pressure water mist can dilute the harmful gases, which any other fire-fighting means can’t. Meanwhile, it has cooling and dust-scrubbing effects.
