目的评估某型静态水气分离器的分离效率。方法采用自行设计搭建的重力条件下地面试验系统,对水气分离器分离效率的评价方法进行了研究,针对激光颗粒测试仪监测法精度不足的问题,提出了重量测试法。采用重量测试法考查了水滴直径、重力以及工作时间等因素对水气分离器分离效率的影响。结果在气体流量为150 L/min,水流量为120~200 g/h的设计条件下,静态测试分离效率平均为(73±11)%,水气分离器气体出口向下动态测试分离效率平均为(87±5)%。同时设计工况下水滴直径和重力对分离效率无影响。结论静态水气分离器分离性能满足设计要求,地面重力条件下水气分离器性能模拟试验方法合理,是水气分离器分离效率研究的有效评价手段。
Purpose To evaluate the separation efficiency of a static water vapor separator. Methods A ground test system under gravity condition was designed and used to evaluate the separation efficiency of the water vapor separator. Aiming at the problem of insufficient accuracy of the laser particle tester, a weight testing method was proposed. The gravimetric method was used to examine the influence of water droplet diameter, gravity and working time on the separation efficiency of water vapor separator. Results Under the condition of gas flow rate of 150 L / min and water flow rate of 120 ~ 200 g / h, the static test separation efficiency averaged (73 ± 11)%, and the gas outlet of the gas separator went down and the dynamic test separation efficiency averaged (87 ± 5)%. At the same time design conditions, the droplet diameter and gravity have no effect on the separation efficiency. Conclusion The separation performance of the static moisture separator meets the design requirements. The simulation experiment of the moisture separator under surface gravity conditions is reasonable, which is an effective evaluation method for the separation efficiency of the moisture separator.
