The researches and applications related to water mist fire extinguishing technology can be traced back to the 1940s and have been developed by leaps and bounds since the 1990s. It uses atomization devices to decompose water flow into droplets, which could extinguish fires, control fires, suppress fires and protect objects.
The fine water mist system used microscopic water droplets as the extinguishing medium. Due to their extremely small particle size, these droplets could quickly absorb heat and effectively lower the temperature of the fire source, all while using a minimal amount of water. This made it adaptable to various types of fires.
Fine water mist effectively mitigates temperature within the source area, hindering combustion reactions and subsequently improving harmful gas generation. Enhanced spray flow rates and cone angles comprehensively cover the source area, thus enhancing fire suppression efficiency. Fig. 5. CO Concentration chart with spray flow rate variation. 4.3.
The suppression efficacy on gas generation is positively correlated with the spray flow rate, spray cone angle, and nozzle flow rate of the fine water mist, while it is negatively correlated with the droplet size of the mist. Additionally, the fine water mist system exhibits a significant suppression effect on gas generation.
The simulation results indicate that the optimal inhibition effect for the energy storage cabin's fine water mist firefighting system is achieved when the spray intensity is ≥24 l/min, the fog cone angle is 76°, nozzle velocity is 10 m/s, and the optimal particle size of the fine water mist is 50 μ m.
Smoke emanated from the fire source, diffusing upwards into the chamber, exhibiting a gradient of concentrations. Overall, the smoke concentration was notably high. Conversely, Fig. 10 (b) portrayed the smoke concentration within the chamber after the activation of the fine mist system.
