Aerosol spray fire extinguishing system and its misuse Accident Analysis
Aerosol fire extinguishing system in the wrong during the operation of jet accidents occurred frequently. The so-called jet mistakenly, that in the absence of fire-fighting equipment Fire The case of non-normal start and spray fire extinguishing agent release. Spray the entire system error occurred after their parts suppliers are affected, often cause-related manufacturers, and use and management of mutual disputes, prevarication, a serious impact on aerosol fire extinguishing Technology Healthy development. Therefore, it is necessary to theory from the pyrotechnics and systems in each part of the role played by the function to be discussed, in order to unify understanding, find out the crux of errors and solutions spray, spraying to eliminate the occurrence of errors. 1 aerosol fire suppression mechanism Aerosol is formed by the agglutination agglutination of aerosols generated from the flame combustion products in the integration of the cooling and condensing solid particles.
Because of its small size, diffusion properties, and can be spread to any corner of the fire-fighting space, and subsidence is weak, particles can protect the space in the fire remain in suspension for long periods, but as a total flooding fire extinguishing agent to use. Aerosol is predominantly gas, solid particles, mainly metal oxides and carbonates, the product gas is N2, a small amount of CO2 and CO, the main endothermic decomposition * cooling effect of solid particles, gas and solid phase Chemical inhibition and dilution of inert gas to achieve fire. Aerosol formation around 1 m diameter of solid particles, the grain size of the particle size is much smaller than Dry powder fire Agent particle size limit. Into the flame of the particles absorb heat from the flame temperature itself (melt function), when the temperature rises to a certain value, the particles melting, vaporization or decomposition, further absorption of heat, the endothermic cooling effect is obvious. For example, K2O in temperature greater than 350 º C when the decomposition, K2CO3, temperature higher than 891 will break down from the endothermic reaction. For small particles, the gasification gas decomposition homogeneous material on the flame inhibition process leading role, and because small particles in the presence of flame in a long time, its inhibition has also been enhanced non-homogeneous . In addition, the gasification of small particles can decompose to cool the flame, thus the existence of the process of aerosol fire extinguishing physical function and role of the synergistic effect of chemical fire-fighting more efficient. Due to the formation of aerosol particles is very small, with strong diffusion, aerosol can flow around obstacles, you can enter the small gap within the gas has a similar nature. Aerosols of solid particles with large surface area, and can fuel the flames of endothermic gasification and decomposition reaction occurs lower flame temperature, the homogeneous and heterogeneous chemical inhibition is very strong, so they have a higher fire effect. 2 aerosol fire extinguishing system components and function of Fire extinguishing system includes three parts: the fire-fighting equipment, control devices and Alarm Device. Fire extinguishing device consists of cartridges, gas generators, box body. Cartridge by the electric igniter, ignition drugs Extinguishing agents And shell composition, drug Softcover within the gas generator. Consumers generally flame gas generator cooling chamber and cooling chambers, generators installed in the cabinets. Only the protective decorative box, a box under the different models can be fitted a number of gas generators. Alarm device, including: Smoke Detector , Temperature detectors, gas discharge lights, sound and light alarm boxes, emergency start and stop buttons. Control device generally has a double-loop fire detection and alarm function, provides fault alarm output, the fire alarm output, can store fire, the operation records. When a fire occurs, the temperature sense, smoke detectors to fire signals are detected, the control unit to issue complex fire alarm. At this point, if the controls are in manual state, the duty officer immediately by an emergency start and stop buttons and controls its own emergency fire-fighting equipment Kai button to start to achieve fire.
