2014年江苏省某金属制品公司发生粉尘爆炸事故,事故后果极为严重。经相关部门调查,该事故的直接原因是事故车间除尘系统长时间未按规定清理,铝粉尘集聚。除尘系统风机开启后,打磨过程产生的高温颗粒在集尘桶上方形成粉尘云。由此可见,爆炸一旦出现,会造成群死群伤,社会影响、法律责任较大。因此,我国在防爆电气研究方面制定了较为严格的国家标准,也取得了明显成绩。1我国防爆特种设备相关标准制定情况
In 2014, a dust explosion accident occurred in a metal products company in Jiangsu Province. The consequences of the accident were extremely serious. Investigation by the relevant departments, the direct cause of the accident is the accident workshop dust removal system for a long time without the required clean-up, aluminum dust accumulation. Dust removal system After the fan is turned on, the high-temperature particles generated by the grinding process form a dust cloud above the dust collection bucket. Thus it can be seen that once an explosion occurs, it will cause mass extinction, social impact and greater legal liability. Therefore, our country has made more stringent national standards in the field of explosion-proof electrical research and made remarkable achievements. 1 China’s explosion-proof special equipment related standards to develop the situation
