摘要
对于添加剂对氨水鼓泡吸收的强化效果进行了实验研究。在吸收过程中，鼓泡特性被高速摄像机记录下来，通过图形分析，得出了鼓泡吸收在各种情况下的最大鼓泡体积、气泡数等参数的变化规律。研究发现，添加剂对氨水鼓泡吸收的总体强化因子可达1．1—1．55。
Experimental investigation of enhancement of ammonia bubble absorption by additives was presented. Ammonia bub- bles generated by continuous gas flow through an orifice emerged in the ammonia water solution were considered. Absorption per- formances of ammonia bubbles were recorded by a high speed camera, and the maximum bubble volume and the bubble genera- tive frequency were analyzed. The overall enhancement factor caused by additives might reach 1.1 - 1.55.
