Fine water mist fire extinguishing equipmentXSW-BZ560QX1 Fire-fighting fine water mist fire suppression system Chengdu fine water mist sprinkler fire extinguishing
Fire extinguishing principle: fine water mist is mainly through the role of cooling, suffocation to extinguish the fire, at the same time has the control of heat radiation, washing the air of smoke auxiliary role.
The key to extinguishing a fine water mist is to reduce the diameter of the droplets to increase the surface area in contact with the surrounding air. The surface area of the same volume of water is atomized into micro-water particles. The increase of surface area makes the fog droplets easier to absorb heat and helps to achieve cooling and extinguishing the fire. The fog droplets after heat absorption are very easy to vaporize, and the volume after vaporization is about1700the concentration of oxygen near the flame is effectively diluted so that the combustion reaction cannot continue. The light weight of the fog drops does not immediately snap to the ground, but as the air flow flies in the air again, increasing the density and uniformity of the droplets in the air. At the same time control thermal radiation, to prevent the spread of fire.
Fine water mist features:
1 Can guarantee long-term water supply, especially suitable for large protective areas;
2 A water tank with a full amount of water can be used or a transitional water tank that can be rehydrated or a direct water source;
3 According to the actual situation of engineering applications or customer requirements custom flow, power;
4 It is applied to the relatively large area of protection, the system cost is low, but the loss of water stains is relatively large.
Introduction to the system
Depending on the structure of the nozzle, the fine water mist extinguishing system is divided into open and closed system. Closed fine water mist extinguishing system is a new type of automatic fire extinguishing system which is proposed by the characteristics of the integrated water extinguishing system and the fire extinguishing mechanism. The system has a water supply component or a component of both water supply and atomization medium, and is equipped with one or more nozzles that can spray fine water mist to control, suppress fire, or extinguish fires. The pipe network of the medium pressure system can withstandMore than 1.2MPaButLess than 3.5MPapressure.
Closed medium pressure fine water mist extinguishing system is using closed medium pressure nozzle, the system can be divided into wet system, pre-acting system and dry system. The dry system pipe is filled with compressed air, no detection system is required, the pipe is automatically activated after the pressure relief, the pre-acting system is in the waiting state, the compressed air in the pipe needs to be started with the detection system, and the pipe is filled with pressure water for the start-up system for a long time when the wet system is in the quasi-working state.
