自分解环境下过氧化氢储存的本质安全设计

INTRINSIC SAFETY DESIGN OF HYDROGEN PEROXIDE STORAGE IN SELF-DECOMPOSI-TION ENVIRONMENT

近年来,过氧化氢储存爆炸事故时有发生,因此有必要基于过氧化氢的热分解爆炸特性,提升其储存的本质安全。介绍了某项目过氧化氢储存的本质安全设计,从单位体积比表面积、自加速分解反应温升、安全距离及泄放面积、散热量等方面,通过设计、校核两级确定过氧化氢储存工艺参数,以降低其热爆炸风险,达到本质安全的要求。

In recent years,explosion accidents occurred frequently in the storage of hydrogen peroxide,so it is necessary to improve the intrinsic safety of its storage based on the thermal decomposition explosion characteristics of hydrogen peroxide.This paper presents the intrinsic safety design of hydrogen peroxide storage in a project.From the aspects of unit volume specific surface area,temperature rise of self-accelerating decomposition reaction,safety distance and discharge area,heat dissipation,etc.,the process parameters of hydrogen peroxide storage are determined through two levels of design and calibration in order to reduce the risk of thermal explosion and to meet the requirements of intrinsic safety.
