摘要

利用关键参数：最小点火能量 (MIE)、尘云最小点火温度 (MITC)、最小爆炸浓度 (MEC)、最大爆炸超压 (Pmax) 和粉尘爆炸特性指数 (Kst)，提出了一种界定粉尘爆炸风险的系统方法。这些参数构成了可靠评估可燃粉尘爆炸风险的基础。根据实验结果，设计了一种安全评估方法，使工厂操作人员能够直接评估粉尘处理过程的安全性，确保有效预防粉尘爆炸。对三种常见粉尘样本（铝、聚乙烯和茄碱）的评估显示了不同的爆炸风险。通过与现有文献的对比分析，本研究调整了风险定义，提出了工艺安全控制的评分方法，以有效降低粉尘云爆炸风险。

Systematizing risk assessment and responses to combustible dust from explosive characteristics

A systematic approach to defining dust explosion risks is presented, utilizing key parameters: minimum ignition energy (MIE), minimum ignition temperature of dust clouds (MITC), minimum explosion concentration (MEC), maximum explosion overpressure (P_max), and the dust explosion characteristic index (K_st). These parameters form the basis for robustly assessing combustible dust explosion risks. Drawing on experimental findings, a safety evaluation method empowering plant operators to directly assess the safety of dust-handling processes was devised, ensuring effective dust explosion prevention. Evaluation of three common dust samples (aluminium, polyethene, and lycopodium) revealed varying explosion risks. Through comparative analysis with existing literature, this study aligns risk definitions, proposing a scoring method for process safety controls to effectively mitigate dust cloud explosion risks.

期刊介绍： The broad scope of the journal is process safety. Process safety is defined as the prevention and mitigation of process-related injuries and damage arising from process incidents involving fire, explosion and toxic release. Such undesired events occur in the process industries during the use, storage, manufacture, handling, and transportation of highly hazardous chemicals.
