港口散粮系统粉尘爆炸危险区域划分方法

Dust Explosive Area Classification Method for Grain Bulking System in Harbor

以国家标准为基础,分析了爆炸性粉尘环境危险性区域划分方法和步骤,以粉尘释放源释放频率和形成爆炸性混合物的可能性为指标,给出了危险区域划分方法,并以某港筒仓系统生产线为例进行了说明,所得结果对于港口散粮系统的安全生产具有借鉴意义。

Based on national standard,the dust explosive area elassifieation method and steps was analysed. Mainly eonsidering the releasing frequeney of the dust release resourees and the possibility of forming explosible hybrids, the elassifieation method was given out . Silo production line of eertain harbor was illustrated as an example, the results may be used by other faetory for referenee.
