Study On Optimization Design Of Water-based Fire Extinguishing Agent And Explosive Dispersal Device

This article uses the orthogonal experiment method to study the formulation of water-based fire extinguishing agent, extinguishing time as the measure to find the best recipe of A:sodium dodecyl sulfate, B:urea, C:EDTA disodium, D:polyethylene glycol (2000), E:ethylene glycol, F:twelve benzene sulfonate andG:cooked powder. The ratio is80:0:4:20:5:20:16. A further improvement of the ingredients of the water-based fire extinguishing agent according to the shortfall in the formulation research experiments of extinguishing volatile organic solvents, focuses on the tertiary butanol, MnCl2solution, the heat generating inert gas substances, fluorocarbon surface and other additives on the fire extinguishing efficiency, on this basis to improve the proportion of each additive in a water-based fire extinguishing agent. Formulated water-based fire extinguishing agent in accordance with the national standards for all aspects of technical performance test and extinguishing experiment, the results showed that the preparation of water-based fire extinguishing agent fully comply with all aspects of the technical requirements prescribed by the State and extinguishing performance. In order to better play water-based extinguishing performance, improve the efficiency of extinguishing the author uses explosion tossed the extinguishing agent. The study of the explosion tossed device mainly in the aspect ratio, the center shed medicine constraint shell and tube the match, center shed dose, the upper and lower ends of the structural strength and other factors, by the high-speed photography the best parameters of the various conditions was the ratio1.5,8#aluminum industrial detonator shell do center drug container,500N pressure, than the dose of0.1%to0.5%, the upper and lower ends of the structure to strengthen, Central explosive dispersal. Based on the parameters produced an1000mL explosive shed fire extinguishing device was made and it successfully control and extinguishing1m2oil pool fire. The fire extinguishing agent dosage and fire extinguishing time has been a qualitative leap compare with traditional extinguishing. Followed the explosion tossed device security study results show that the device is safe and reliable without damage to persons and objects. Finally, simulation the pressure of the explosion tossed process use ANSYS/LS-DYNA, the simulated shows that the the explosion tossed process security and reliability in some extent explains.
