摘　　要：采用单气泡实验对SK型静态混合器内气-液间混合过程进行试验研究,针对主流速度、气泡尺寸、混合元件数量等参数对气-液混合效果差异进行实验研究,并就整个混合过程中的压降波动进行了分析。实验结果表明,SK型静态混合器增大气-液两相相界面,提高气-液两相混合效果,延长气-液停留时间,混合元件数增加压力降增大。The mixing process of gas-liquid was studied by researching the movement of single bubble in SK static mixer. Impact of flow rate of solution, size of bubble, number of mixing elements on gas-liquid mixing was investigated, and the pressure drop was also analyzed. The result shows that the SK static mixer can increase gas-liquid two phase interface, improve the gas-liquid two phase mixing efficiency, prolong the gas-liquid residence time; the pressure drop increases with the increasing of mixing element number.
