摘　　要：介绍了一种新型、节能的用于自吸式中心龙卷流型搅拌反应器的折叶形气体分散器。借助CFD仿真模拟技术,对叶片竖直段高度分别为10、15、20mm的折叶形气体分散器和普通气体分散器进行液相单相流模拟。分析得出,安装有竖直边高度为10mm折叶形气体分散器的中心龙卷流型组合反应器有较好的气体分散性能和搅拌混合性能;15mm折叶形气体分散器可以避免搅拌死角的出现。A new energy-saving folding-shaped and self-suction gas disperser for tornado flow stirring reactor was introduced. Making use of CFD technology, the liquid flow simulation in the self-suction folding-shaped gas disperser and in the general gas disperser with 10mm, 15mm and 20mm-height vertical edges were imple- mented respectively to show that, the tornado flow stirring reactor equipped with a 10mm-height vertical edge folding-shaped disperser boasts good performances in gas dispersion and mixing, and the folding-shaped dis- perser with a 15mm-height vertical edge can avoid occurrence of dead stirring areas.
