摘　　要：为研究含砷毒剂路易氏剂的焚烧销毁特性,对路易氏剂在柴油焚烧炉中的焚烧过程进行了数值模拟。对焚烧过程中的温度分布、流场、O_(2)/CO_(2)浓度、NO_(x)浓度、路易氏剂气态浓度、重要中间体浓度、As_(2)O_(3)浓度分布进行了分析研究。结果表明,选用的柴油焚烧炉在合适的柴油燃烧负荷和一次风/二次风配风条件下,可以实现对路易氏剂的焚烧销毁。路易氏剂气态浓度和重要中间体浓度分布表明,路易氏剂在一燃室底部的高温强混合场内发生了快速的化学反应。重要含砷产物As_(2)O_(3)在焚烧过程中快速生成,在一燃室底部和整个二燃室均具有较高的浓度。To investigate the incineration characteristics of arsenical agent lewisite,numerical simulations were conducted on the incineration process of lewisite in a diesel incinerator.Temperature distribution,flow field,O_(2)/CO_(2) concentrations,NO_(x) concentrations,gaseous lewisite concentration,key intermediate species concentrations and As_(2)O_(3) concentration distribution throughout the incineration process were analyzed.The findings suggested that the diesel incinerator could effectively destroy lewisite under appropriate diesel combustion loads and primary/secondary air supply conditions.The distribution of gaseous lewisite and crucial intermediate species concentrations indicated rapid chemical reactions occurring within the hightemperature,intensely mixed zone at the bottom of the primary combustion chamber.Significant arsenical product As_(2)O_(3) was rapidly generated during the incineration process,with elevated levels observed at the bottom of the primary chamber and throughout the secondary chamber.
