摘要 针对医院放射科室七氟丙烷灭火后排风系统进行了理论分析,分析认为,当换气次数为5次/h时,七氟丙烷浓度降到初始浓度的一半的时间分别大约为8.5分钟。笔者结合具体工程实践提供了几种七氟丙烷灭火后排风的设计方案,各种设计方案各有优缺点,需根据具体平面布局和使用要求灵活选择方法,并提出了一种拆装式七氟丙烷灭火后排风的想法。最后指出并强调了七氟丙烷灭火后排风机电气设计注意问题。 Theoretical analysis of heptafluoropropane fire-fighting exhaust system in radiation department of hospital has been carried out,and it is concluded that when the number of air changes is 5 times per hour,and the time for heptafluoropropane to reduce to half of the initial concentration is about 8.5 minutes.The author provides several design schemes of heptafluoropropane fire-extinguishing exhaust system combining with specific engineering practice,every design has its own advantages and disadvantages and engineers need to choose methods flexibly according to specific layout and use requirements.The idea of a dismounted heptafluoropropane fire extinguishing exhaust air system is put forward.At last,it points out and emphasizes the problems in the electrical design of the fan after heptafluoropropane fire extinguishing。Through this paper,the author hopes to provide reference for the design of heptafluoropropane fire-fighting exhaust system in radiation department of hospital.
