粉尘爆炸是可以预防的,通过消除“可燃性粉尘”“氧化剂”“点火源”中一个或多个要素,来实现。近年来,随着粉体制造加工企业越来越多,尤其是工贸行业中涉及产生粉尘的工艺环节越来越多,由于管理缺陷、安全意识薄弱、粉尘爆炸科学知识缺乏等原因,粉尘爆炸事故频发。科学合理地评估粉尘爆炸风险性,一直是企业和政府各级安全生产监管部门当前应高度 Dust explosions can be prevented by eliminating one or more of the elements of “flammable dust”, “oxidizer”, “ignition source”. In recent years, with more and more powder manufacturing and processing enterprises, especially industrial and commercial sectors involved in dust production process more and more due to management defects, lack of safety awareness, lack of scientific knowledge of dust explosion and other reasons, dust explosion Frequent accidents. Scientifically and rationally assessing the risk of dust explosion has been the current height of safety supervision departments at enterprises and governments at all levels
