摘要: 用响应面分析法分析不同排液结构对新式异型折流板除雾器气液分离性能的影响,并对排液结构参数进行优化设计. 通过单因素实验对比筛选对除雾器性能具有显著影响的关键参数,用中心复合设计实验建立响应面多元回归模型,分析影响除雾器性能系数的参数间交互作用,得出最优参数. 结果表明,影响除雾器性能参数的最优取值为分离气速2.6 m/s、排液钩高度7.3 mm、前置排液槽和后置排液槽宽度分别为3.1和2.3 mm. 优化的折流板除雾器性能系数计算值为2.073,实验值为1.875,优化结果较可靠.

Abstract: The influences of different drainage structures on the gas?liquid separation performance of wave-plate mist eliminator were analyzed and the parameters of drainage structure were optimized by response surface methodology. The single factor experiment was used to select the key parameters which had significant influence on the performance of the mist eliminator. The multivariate regression model was established using center compound design experiment in order to analyz the interaction of parameters which had influence on mist eliminator performance coefficient. The results showed that the key parameters which had significant influence on the performance of the mist eliminator and their values were separation gas velocity 2.6 m/s, height of drainage hook 7.3 mm, width of front-drainage pocket 3.1 mm and width of rear-drainage pocket 2.3 mm. The calculated value of mist eliminator performance coefficient was 2.073 while the test value was 1.875 which indicated that the optimization result of response surface methodology was credible.
