Description

Intermittent atomizing injector and intermittent atomizing injection system

Technical Field

The utility model relates to a extinguishing device technical field, concretely relates to intermittent type formula atomizing sprayer and intermittent type formula atomizing injection system.

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 the water which plays the three roles to the sprinkled fire extinguishing agent water is very small, because the water can be separated from the fire stove under the action of gravity, and the speed is very high, so that the fire extinguishing agent water is separated from the fire extinguishing task early. Moreover, the water participating in the heat absorption has weak heat absorption capacity in a heat absorption stage, so that the utilization rate of the water is extremely low when the sprinkling type fire extinguishing is adopted.

In the prior art, atomized water can be adopted for fire extinguishing, so that the fire extinguishing efficiency is improved. The principle of atomized water fire extinguishing is that high-pressure gas in an energy storage cavity is discharged by utilizing a quick-opening technology, water stored in the container in advance is quickly pushed out of the container, the water collides with air in the flying process, fog drops with different particle sizes are formed in different flying stages, and the particle size of the fog drops is smaller when the water flies farther. The atomization process takes place in a short time, the contact surface area between the fog drops formed after the water mass is atomized and the combustion objects and the combustion space is increased, and the volume of the water mass is reduced due to the atomization, so that the fog drops can absorb heat and be gasified quickly to form gaseous water. During the phase change from liquid to gas, the water in unit mass absorbs more heat than at any time, and the absorbed heat is the main aspect of fire extinguishing, which can reduce the temperature of the fire scene. For example, the heat of hydration of 1Kg of water is 2200 KJ.

Since fire fighting is a process that behaves differently at each stage, it is also necessary that each stage is operated in a different manner. The combustion of each part of the fire field is also unbalanced, the combustion heat intensity of each point is different due to various factors such as the types of combustion objects of each point, the influence of airflow on each point during combustion, the temperature field where each point is located and the like. Therefore, under certain circumstances, individual soldiers are required to enter the fire extinguishing system under certain conditions, and the fire extinguishing speed is increased by using equipment in hands. Therefore, a fire extinguishing apparatus with high fire extinguishing efficiency for individual soldiers is needed.
