Fine Mist Sprayer Pump Wholesaler introduces the fire extinguishing mechanism and scope of application of water mist nozzles

1. The fire extinguishing mechanism of the water mist nozzle system:

①Extinguishing mechanism: heat absorption cooling, oxygen suffocation, radiant heat blocking, wetting effect

② Endothermic cooling: Water spray also has this extinguishing mechanism

③Radiant heat barrier: The fine mist falls on the flame, and through the barrier with the air, the oxygen drops, the air cannot enter, and the heat cannot be released. The unique fire extinguishing mechanism of water spray is not found in water spray.

④ Wetting effect: Water spray also has this extinguishing mechanism.

2. The scope of application of the water mist nozzle system

①Energy saving and environmental protection of water mist nozzle:

1) The human body is harmless, does not affect the environment, and does not produce harmful decomposition substances at high temperatures

2) Water consumption of ordinary water mist nozzle fire extinguishing system = 70%~90% of automatic sprinkler system. Therefore, water mist fire extinguishing system can reduce the volume of system pipes and fire water tanks. Water consumption of fine water mist fire extinguishing system = ordinary Less than 20% of the water spray fire extinguishing system, reducing the energy consumption of the system. Electrical insulation: The particle size of the water mist is small. The test results show that the power frequency AC flashover will not occur under the three voltage levels of 220KV, 110KV and 35KV. The water is discontinuous during spraying, so it is electrically insulated. The performance is better. Smoke removal effect: After the water mist evaporates, it is beneficial to evacuation and firefighters' fire rescue work. The volume expands to fill the entire fire space and combines with the free carbon formed by combustion to effectively remove corrosive and toxic substances in the smoke.

②The scope of application of the water mist nozzle fire extinguishing system, flammable solid fires (level a) can effectively save flammable solid surface fires in a relatively closed space, including solid fires such as paper, wood, textiles, plastic foam, and rubber. Flammable liquid fires (type b) are more flammable liquid fires in enclosed spaces.
