Hazard Analysis and Protective Countermeasures of Dust Explosion in Dedusting System

摘要

High risk of dust explosion exists in the dust removal system during industrial production process, which results in occurrence of dust explosion. Though summing up numerous accidents, the cases study clarifies that dust explosion in the dust removal system is prone to be multiple and continuous, which has serious consequences. By distinguishing different ignition resources which induce dust explosion, the accidents are classified into four models respectively triggered by fire, auto-ignition of combustive dust, static electricity and impact-friction. Otherwise, the protective countermeasures about technology and management are proposed.
