摘要
为掌握次磷酸盐阻化剂对煤的阻燃机理,了解煤在氧化过程中微观结构的变化规律,采用傅里叶变换红外光谱仪,对加入次磷酸铝和次磷酸钠阻化剂处理过的煤样分析其红外光谱图。通过研究阻化前后煤分子微观结构变化特征,分析了次磷酸铝与次磷酸钠对煤在低温下的阻化效果。结果表明:在氧化升温过程中对煤使用阻化剂,煤结构中起阻化作用的是含氧官能团、芳香烃和脂肪烃3类活性基团,含氧官能团起主要作用,芳香烃起次要作用,脂肪烃作用最小;随氧化温度升高,RCH_3基团和R_2CH_2基团氧化反应活性不同,次磷酸盐阻化剂在升温前期阻化效果明显,超过一定温度后不起阻化作用,但对含氧官能团—C—O均保持一定的阻化作用。
In order to grasp the hypophosphite inhibitor mechanism for coal combustion,and understand the change rule of microstructure in the process of oxidation of coal,by using Fourier transform infrared spectrometer,the infrared spectra of the coal samples with the inhibitor agent treated with the addition of aluminum hypophosphite and sodium hypophosphite were analyzed.Through studying the molecular microscopic structure changing characteristics before and after the process of oxidation inhibitor,the paper analyzed the resistance effect of aluminum hypophosphite and sodium hypophosphite on coal at low temperature.The results showed that using inhibitor for coal in oxidation heating process,three kinds of active groups,oxygen containing functional groups,aromatics hydrocarbons and fatty hydrocarbon played a role of inhibitor in the coal structure,containing oxygen functional groups played a major role,aromatic hydrocarbons played a secondary role,and finally the aliphatic hydrocarbons.With increasing oxidation temperature,RCH_3 groups and R_2CH_2 group oxidation reaction activity was different,the resistance effect of hypophosphite inhibitor was obvious in the early stage of heating up,and had no inhibitor effect after over a certain temperature,the oxygen containing functional group —C—O was kept the inhibitor function to some extent.
