燃爆抑制粉体及其抑制机理研究进展
Research progress on explosion-suppressing powders and suppressing mechanisms
摘要
Abstract
The leakage of combustible gas could lead to serious explosion accidents,which could cause great damage to people's lives and property.Explosion suppression technology can effectively reduce the consequences of the explosion accidents,which is an important part of combustible gas explosion safety protection technology.As the core component of explosion suppression device,the performance of the explosion suppressant can directly affect the reliability of explosion suppression system.The research results in the field of explosion suppression at home and abroad are focused on,and the explosion suppression powder and its inhibition mechanism are systematically summarized and analyzed.Based on the different compositions,the explosion suppressing powder is divided into one-component and compound materials.According to the difference of the suppressing mechanism,the one-component suppressing powder is divided into active powder and inert powder.Due to the synergetic effects of different substances,the development of the compound material is the research hotspot.In the literature review part,this paper follows the structure"General introduction of powder materials—Related experimental and theoretical research—Suppression mechanism summary".The first part provides the general introduction of the material,including the origin,structure and property.The second part offers the summary of the related research result about the material.The third part focuses on the physical and chemical suppression mechanism of different material,which contributes to the deeper understanding of the suppression effect.Finally,the existing problems of the research at present is summarized and the development of the future research work is discussed.In addition,this article proposes to standardize the testing process,emphasizes the use of numerical simulation to guide the suppressing of material synthesis and reduce the blindness of research.The aim of this review is to provide scientific understanding and technical support for the development of high-efficiency explosion suppression technology.关键词
