单重态氧发生器作为氧碘化学激光的核心部件, 为化学激光器提供化学能。通过对工业喷射器及旋风分离器的研究, 结合产生单重态氧的化学反应环境, 进行了大量模拟及设计改进工作, 研制了一种新型喷射型单重态氧发生器, 并进行了相关实验研究。喷射型单重态氧发生器利用喷嘴能够产生比传统发生器类型更多的气液表面, 获得足够的反应效率, 可以大幅度降低发生器液体使用量, 从而减小发生器辅助系统, 提高体积效率。为满足O2(1Δ)停留时间短及分离效率高的要求, 利用气液两相喷射的高初速度以旋风分离器完成气液分离。新型发生器氯气利用率可达97%~99%, 其O2(1Δ)产率为40%~50%。

As the heart of chemical oxygen iodine laser (COIL), the singlet oxygen generator (SOG) has been focus of research for many years. A novel eject singlet oxygen generator was designed based on research of industrial ejectors and cyclone separators. Simulations and experiments were performed on the chemical reaction of O2(1Δ). This eject SOG can make larger gas-liquid surface area through nozzle compared with traditional SOGs, and therefore it has a high chemical efficiency. Gas and liquid were separated by a cyclone separator which was designed to fit for the high separation efficiency and low residence time. This SOG has a chlorine utilization of 97%-99% and O2(1Δ) yield of 40%-50%.
