摘　　要：某制氢装置的生产单元与目标设防建筑物(机柜间)位于同一高阻塞框架内,存在安全防护风险,一旦氢气泄漏引起爆炸,可能会造成重大人员伤亡和财产损失。通过建立等比例三维模型,将该制氢装置内发生氢气泄漏后形成的氢气云作为爆炸源,基于FLACS软件三维模拟研究其建筑物内部架构空间高阻塞度环境下氢气云爆炸后的灾害后果,确定了现有结构下的事故最大影响范围。结果显示,该制氢装置氢气云发生燃爆事故后,产生最大爆炸超压为14.6 kPa,作用时间45 ms,建筑物损坏程度为完全倒塌和全部破坏之间。因此需对机柜间进行抗爆加固改造,提出了喷涂3 mm防护涂层,并采取结构加固的改造思路。研究结果可为类似环境下氢气爆炸的抗爆评估,以及同类框架厂房内设防目标区域的抗爆改造提供参考。The production unit of a hydrogen production facility and the protected target building(cabinet room)are located within the same high blocking frame,which poses a safety protection risk.Once hydrogen gas leaks and causes an explosion,it may cause significant casualties and property damage.By establishing a proportional 3D model,the hydrogen cloud formed after hydrogen leakage in the hydrogen production unit was used as the explosion source.Based on FLACS software 3D simulation,the disaster consequences of hydrogen cloud explosion in the high blockage environment of the building′s internal architecture space were studied,and the maximum impact range of the accident under the existing structure was determined.The results showed that after a hydrogen gas cloud explosion accident occurred in the hydrogen production unit,the maximum explosion overpressure was 14.6 kPa,with a duration of 45 ms.The degree of damage to the building was between complete collapse and complete destruction.Therefore,in order to carry out anti-explosion reinforcement and renovation of the cabinet room,a renovation idea of spraying a 3 mm protective coating and adopting structural reinforcement was proposed.The research results can provide reference for the anti explosion assessment of hydrogen explosions in similar environments,as well as the anti explosion renovation of target areas in similar framework factories.
