Description

Impact type nozzle capable of adjusting atomization particle size and range

Technical Field

The invention relates to the technical field of nozzle structures, in particular to an impact type nozzle capable of adjusting the atomizing particle size and range.

Background

The highway tunnel is a relatively closed system, and if a fire disaster occurs, under the comprehensive action of factors such as dense smoke, high temperature and the like, rescue is difficult, and economic loss caused by the fire disaster is huge. The impact type fine water mist nozzle is generally concerned by the tunnel fire fighting industry due to the characteristics of high efficiency, environmental protection and wide applicability. The impact type fine water mist nozzle can spray water mist to extinguish fire only by opening a switch of a water supply pipe network, and the sprayed water mist can further adsorb solid smoke particles to prevent trapped people from poisoning and dying due to the fact that the trapped people inhale toxic gas.

The impact type nozzle impacts the metal surface through water flow ejected from the firing pin to change the speed distribution condition of the jet flow section and break and atomize water particles. The atomized liquid particles can reduce the temperature near the fire source and isolate oxygen, thereby achieving the purpose of fire extinguishing. Once the traditional impact type fine water mist nozzle is selected, the spraying particle size and the spraying range are basically determined and cannot be flexibly adjusted according to the actual working condition. Because the fine water mist with specific particle size has different influences on the initial stage, the growth stage, the stable combustion and the growth stage of the fire development, particularly under the co-coupling action with a fan, the fire extinguishing effect is related to the particle size of the mist. The fire extinguishing effect is poor by adopting the water mist with single particle size. If parameters such as spray particle size are adjusted by changing the water pressure at the nozzle, the requirement on a pipe network is high, the installation and later maintenance costs are high, and the economical efficiency is poor.
