摘要:
引入湍流涡耗散概念(EDC)模型,以昆明市某沙发工厂火灾,获得了含有HCN的火灾烟气浓度的时空分布,采用N-GAS模型来评价火灾烟气综合毒性并讨论HCN对于多组分烟气耦合毒性的影响。为了讨论HCN对火灾烟气毒性的影响,本文进行了A、B两组模拟计算,A组烟气组分不包含HCN,B组烟气组分包含HCN。将A、B两组的模拟结果进行对比,验证了引入EDC模型、讨论HCN对多组分火灾烟气毒性的影响具有可行性。基于N-GAS模型的计算结果,说明了HCN气体对于多组分烟气的耦合毒性的影响不可忽略,有时甚至起着至关重要的作用。
Abstract:
In this paper, the temporal-spatial distribution of concentration of fire effluents with HCN was obtained through the eddy dissipation concept (EDC) model and a case study on a fire in a sofa factory in Kunming. N-GAS model was used to assess smoke toxicity, and the impact of HCN HCN on fire smoke toxicity was also discussed. To discuss the impact of HCN on fire effluents toxicity, two sets of simulation—set A and set B were carried out with the former being without HCN and the latter containing HCN . Contrast between the simulation results of sets A and B verifies the feasibility of introducing eddy dissipation concept model in this simulation and of discussing the impact of HCN on fire smoke toxicity. Calculation results based on N-GAS model show that HCN has a non-negligible and sometimes even an important influence on toxicity of fire smoke toxicity.
