粉尘爆炸研究方向初探

THE DISCUSSION OF DUST EXPLOSION TOPICS

本文从现有的对粉尘爆炸特性的认识出发,分析了粉尘云特性,粉尘爆炸与爆轰,湍流对反应波阵面的加速几个方面,提出了近期应该在粉尘爆炸参数测试技术标准化、粉尘指数K_(st)、粉尘爆燃转炸轰的过程、泄炸机理以及控炸装置和控炸设计规范等方面的研究上下功夫,以便更有效地利用现有的试验条件,更快、更多、更好地解决工程实际问题。

From the current knowledge of dust explosion, it is analysed the characteristic of dust cloud, dust deflagration and detonation, the flame acceleration by turbulence in this paper. It is proposed that it should concentrate on the standardization of experimental technique, the dust index Kst, the process from deflagration to detonation, the mechanism of vent, the device and design standard of controling explosion etc., so that it can solve practice problems quickly, better and more by using the experimental devices on hand more effectively.
