可燃物爆炸抑制的研究现状及发展

The present research situation and development of combustible explosion suppression

从实验研究、数值模拟和微观反应机理三个方面概括总结了近年来可燃物爆炸抑制的研究现状,总结了现阶段的研究成果,指出了研究中存在的不足。实验研究主要涉及卤代烃、水、干粉这三种抑制剂,研究了这三种抑制剂的制效果及优缺点;理论计算主要阐述爆炸及其抑制的反应特性、反应机理,现阶段的理论研究以宏观反应机理为主,缺乏对爆炸及其抑制的微观机理的研究,对爆炸及其抑制的本质认识不够。基于以上原因,对今后的研究方向进行了展望。

This presently research situation of the combustible explosion suppression was introduced separately from the experimental study,the numerical simulation and the Micro-reaction mechanisn.The results of the study at this stage were summarized,and the shortcomings in the study were pointed out.Taking halogenated hydrocarbons,water and dry powder as inhibitors,the suppression effect and their advantages of three inhibitors were introduced.The theoretical calculations mainly described the characteristics and the reaction mechanism of the explosion and its suppression.The research focused on the macroscopic reaction mechanism now,being lack of research on the microscopic mechanism of the explosion and its suppression,and being lack of understanding of the nature of explosions and their suppression.For the above reasons,future research directions were prospected at the end of this article.
