Background
The highway tunnel is a relatively closed system, and if a fire disaster occurs, rescue is difficult under the comprehensive actions of dense smoke, high temperature and other factors, and economic loss caused by the fire disaster is huge. The impact type water mist nozzle is widely focused by the tunnel fire-fighting industry due to the characteristics of high efficiency, environmental protection and wide applicability. The impact type water mist nozzle can spray water mist to extinguish fire only by opening a water supply network switch, and the sprayed water mist can further adsorb solid smoke particles to prevent trapped personnel from poisoning and dying due to toxic gas inhalation.
The impact nozzle impacts the metal surface through the water flow emitted by the firing pin, changes the speed distribution condition of the section of the jet flow and breaks up and atomizes water particles. The atomized liquid small particles can reduce the temperature near the fire source and isolate oxygen, thereby realizing the aim of fire extinguishment. Once the traditional impact type water mist nozzle is selected, the jet particle size and range of the traditional impact type water mist nozzle are basically determined, and the traditional impact type water mist nozzle cannot be flexibly adjusted according to actual working conditions. Because the water mist with specific particle size has different influences on the initial stage, the growth stage, the stable combustion and the growth stage of fire development, particularly under the combined action of the fan, the fire extinguishing effect is related to the particle size of the spray. Adopts fine water mist with single particle size, and has poor fire extinguishing effect. If parameters such as spray grain size and the like are regulated by changing the water pressure at the nozzle, the requirement on a pipeline network is higher, the installation and later maintenance cost is higher, and the economical efficiency is poor.
