为进一步提高电厂湿法脱硫后的烟气除雾效果
设计了一种新型的部分回流式两级分离轴流旋风分离器并为此搭建了旋风分离器性能测试实验台
通过液滴雾化装置产生了不同粒径液滴
采用Malvern激光粒度分析仪对设计的几种结构分离器的进、出口粒径分布进行了测试
对不同结构分离器在不同工况下的分离效率和阻力损失进行了测试。实验结果表明:分离器的分离效率随回流槽数量的增加而提高
内筒顶部回流槽数增加1倍
筒内气流速度为3.9 m/s时
分离器效率提高66.78%; 回流槽集中分布在分离器顶部比回流槽分布在分离器内筒上、中、下时的效率提高得更加显著
当筒内气流速度为3.94 m/s时
分离效率可提高16.9%; 中间导流管高度对分离效果也有一定影响
当导流管高度与分离器高度比为0.32时
分离效果最佳。
To further enhance the efficiency of demister in a flue-gas after desulfuration by wet processes for power plant
a new type of partial reflux cyclone separator with two separation stages is proposed. An experiment rig is constructed to test the performance of cyclone separator
and a droplets generator is designed to produce liquid droplets with different diameters. Malvern particle size analyzer is adopted to obtain the droplet diameter distribution at the inlet and outlet of the separator
and the separation efficiency and resistance loss are measured for different separator parameters under various working conditions. The experiments show that the separation efficiency rises with the increasing number of reflux tanks. At the inlet velocity of 3.9 m/s
the efficiency of separator rises by 66.78% in the case of doubled number of reflux tanks. The efficiency of separator with reflux tanks centered on the separator top reaches higher than that with reflux tanks scattered along the separator. At the inlet velocity of 3.94 m/s
the efficiency rises by16.9%. The height of guide tube affects the efficiency of separator and there exists an optimum ratio of 0.32 between the height of guide tube and the separator.
