油品火灾改性干水材料灭火效能试验
Experimental study on fire extinguishing efficiency of modified dry water material for oil fires
摘要
Abstract
Four types of modified dry water samples(DW)with different components were developed and ready for use in oil leakage incidents.The fire extinguishing experiment platform was constructed to investigate the fire extinguishing effectiveness of several DW groups on oil fires.The characteriza-tion and analysis were performed using an optical microscope,a laser particle size analyzer,and a ther-mogravimetric analyzer.The findings demonstrate that the prepared DW has a robust core-shell struc-ture and its interior water content can range from 80%to 90%.The volume density of the fire extin-guishing agents and gels can be increased,which helps the agent reach the flame root more effectively and boost the efficacy of fire extinguishing.In the fire extinguishing test,the pure water DW1 fire is extinguished in 49 s,whereas the fire is extinguished in 17 s when DW4 is added with potassium ox-alate and gel agent.This represents a 65.3%reduction in fire extinguishing time,fully utilizing the role of physical and chemical inhibition and significantly cutting down on fire extinguishing time.The findings have significant implications for the petrochemical industry's use of dry water extinguishing agents.关键词
