摘要：

设计和搭建了全氟己酮灭火剂抑制B类火焰效应实验系统和过火尾气采集装置，以此研究了灭火瓶充装压力对灭火过程中瓶内压力、喷嘴处压力、灭火剂输出流量、灭火时间和过火尾气组成的影响，采用离子色谱法测试尾气中HF含量，用气质联用法分析尾气的其它气体组分。结果表明，充装压力从1.5 MPa增加至4.2 MPa时，灭火剂喷射流量逐渐增大。充装压力在1.5～2.5 MPa时，喷射流量增幅约为30%，在2.5～4.2 MPa，喷射流量增幅约5%；随着充装压力的增加，过火尾气中氟化氢含量逐渐减少，降幅约40%。过火尾气中还含有六氟丙烯、七氟丙烷、全氟丙烷及全氟庚烷等含氟气体。

Abstract:

 In this paper, an experimental system was designed and set up to investigate the relationship between the filling pressure of FK-5-1-12 and the response of suppressing class B fire, which composed of a experimental device of suppressingclass B fire with FK-5-1-12 and collection device of exhaust.The pressure in fire-extinguishing bottle, pressure at nozzle, mass flow of FK-5-1-12, fire-extinguishing time and the exhaust composition were measured respectively at the different filling pressure of fire-extinguishing bottle. The HF content in the exhaust was measured by Ion chromatography method and the other gas component was measured by GC-MS. The results showed that the mass flow rate increased as the filling pressure was increased from 1.5 MPa to 4.2 MPa.The increment of mass flow was about 30% when the filling pressure was between 1.5 MPa and 2.5 MPa. That growth rate was about 5% when the filling pressure was between 2.5 MPa and 4.2 MPa.The HF quantity inexhausted was decreased by 40% at the same time. Besides，the hexafluoropropylene, heptafluoropropane, perfluoropropane, perfluoroheptane were detected inexhausted.
