Description
Technical Field

Background
Water is cheap and easily available, so that water is a relatively common fire extinguishing agent when extinguishing fire. The traditional fire extinguishing mode using water is mainly a sprinkling type, namely a fire extinguishing mode of directly splashing water to a comburent. The splashing type fire extinguishing has the following characteristics that 1, the splashing type fire extinguishing agent has a heat absorption effect, the fire extinguishing agent is directly splashed or sprayed to a combustion object, and partial water can absorb heat released by combustion of the combustion object; 2. the microstructure on the surface of the combustion object can delay the flow speed of water and change the water flow direction, and prolong the retention time of the fire extinguishing agent water on the surface of the combustion object; 3. due to the action of gravity, water will flow to a position where the potential energy is lower; 4. most of the water entering the combustion space is at normal temperature and cannot be gasified quickly; 5. has a covering effect of covering the combustion products, the covering effect of water on the combustion products is usually shown on the flow path of the water; 6. the shock wave effect is realized, namely the impact effect of high-speed flow on combustion products is realized; 7. if the combustion products are wood, the fire extinguishing agent has wetting action, i.e. humidifying action. The most prominent features of the sprinkled fire-extinguishing system are heat absorption, impact and covering. However, the proportion of water to the sprinkled agent water is small because the water is forced by gravity to escape the combustion products, which is so fast that the agent water is released from the fire-extinguishing task early. Moreover, the water participating in the heat absorption has weak heat absorption capacity compared with the heat absorption stage, so that the sprinkling type fire extinguishing has strong fire extinguishing capacity, but the utilization rate of the water is too low.
