Temperature variation and smoke composition of flame-retardant conveyor belt in the early stage of friction accident

  • 摘要: 为实现带式输送机火灾早期预警,改进滚筒摩擦实验平台并监测阻燃输送带温度。利用质谱(MS)技术,分析钢丝绳芯阻燃输送带在摩擦事故早期的升温规律与烟气成分。研究表明,随着摩擦持续进行,阻燃输送带表面温度分布呈现出较强的对称性,最高温度区域逐渐向输送带中心集聚,烟气成分随温度变化而改变。根据实验中烟气产物主要成分以及对应的反应过程,将钢丝绳芯阻燃输送带升温过程分为氧化反应阶段(环境温度至100 ℃)、取代反应阶段(100~160.2 ℃)和热解反应阶段(160.2 ℃以后)。当阻燃输送带处于氧化反应阶段时,输送带热容量较小、升温快,产物多为烷基和酯类化合物;取代反应阶段热容量逐渐增加,升温放缓,产物多为硝基、醚类、羧酸类化合物;热解反应阶段输送带内部热容量基本稳定,升温速率最小,在160.2 ℃时在烟气成分中首次检测到含氯化合物。
