摘要
对氧碘化学激光器的单重态氧发生器(SOG)进行了改进,采用横向射流方式,并对该横向射流式单重态氧发生器的性能进行了检测。实验中过氧化氢碱溶液温度控制在-16℃左右,氯气流量为530mmol/s,He与氯气的流量比为3;采用PS法测量单重态氧分子的产率,吸收法测量氯气的利用率和相对水含量。得出如下结论:在不使用冷阱和分离器的情况下,最高单重态氧分子产率达到58%,氯气利用率在80%以上,相对水含量小于等于0.5;气体达到最大流量时,发生器仍然能稳定地工作。
A transverse jet singlet oxygen generator (TJSOG) with BHP liquid driven by a pump circulation was demonstrated. This TJSOG represents the trend for its engineering scalability. In the initial experimental stage, a singlet oxygen yield of 58% was obtained for a chlorine flowrate of 530mmol/s, corresponding to a chlorine utilization of above 80% and a relative water vapor concentration no more than 0.5. The O2 (~1Δ) and the water vapor content in the gas were determined from the emission of the 1 270nm and 762nm wavelength, respectively, according to the Piston-Source method. Chlorine untilization was measured by detecting the absorption of 340nm light by residual chlorine. The TJSOG can work steadily when the total gas flow rate reaches the maximum.
