摘要:
为深入研究二氧化碳的惰化机理，构造容积超过200 m3、平均泄压速率569.1 Pa/h的气密设施，布置10个多种环境参数传感装置，开发多参量信号采集、显示、存储的监测监控平台，利用液体储存、直注和气化灌注设备，研究密闭空间中液气物理形态二氧化碳的火源缺氧熄灭惰化特性，确定木材和汽油燃烧熄灭的二氧化碳和氧浓度阈值。研究结果表明：管路末端注入参数相同时液体的阻燃性更强；木材和汽油燃烧物的火源熄灭时氧浓度分别不超过18.43%，16.98%，注入的二氧化碳浓度分别不低于15.9%，28.6%，可定性反映液态汽油比固态木材更易燃的物理特性。研究结果可为精确指导二氧化碳的科学定量注入提供参考。
Abstract:
In order to further research the inerting mechanism of carbon dioxide,an air-tight facility with the volume exceeding 200 m3 and the average pressure relief rate of 569.1 Pa/h was constructed,then 10 sensing devices of multiple environmental parameters were arranged,and a monitoring and control platform for the acquisition,display and storage of multi-parameter signals was developed.Using the equipment of liquid storage,direct injection and gasification perfusion,the inerting characteristics of carbon dioxide with liquid and gas physical forms for the fire source hypoxia extinction in the air-tight space were studied,and the carbon dioxide and oxygen concentration thresholds for extinguishing the wood and gasoline burning were determined.The results show that the flame retardancy of liquid is stronger under the same injection parameters at the end of pipeline.When the fire source of wood and gasoline combustibles is extinguished,the oxygen concentration do not exceed 18.43% and 16.98% respectively,and the injected carbon dioxide concentration do not be less than 15.9% and 28.6% respectively,so the physical properties of liquid gasoline more flammable than solid wood can be qualitatively projected.The research results can provide reference for accurately guiding the scientific and quantitative injection of carbon dioxide.
