干燥设备爆燃事故技术分析

Technical Analysis of Deflagration Accident in Drying Equipment

对某公司发生的一起干燥设备爆燃事故进行了技术分析。认为直接原因是甲醇等气体与空气混合达到爆炸极限,遇开关柜电气火花点燃发生爆炸,间接原因包括非防爆开关柜易产生电气火花、现场可燃气体报警器。

A technical analysis of the explosion of a dry equipment in a company was carried out.The direct reason was that the mixture of gas and air such as methanol reached the explosion limit, and the electric spark ignition of the switchgear exploded.Indirect reasons include non-explosion-proof switchgear prone to electrical sparks, on-site combustible gas alarm.
