泡沫分离设备及工艺的研究进展

Advance in research and development of foam fractionation devices and technologies

泡沫分离技术是近些年得到重视的分离技术之一。泡沫分离设备依据设备结构和操作方式的不同分为简单泡沫塔和复杂泡沫塔。简单泡沫塔的操作方式包括批式操作、半批式操作、连续操作和半连续操作;复杂泡沫塔包括多级泡沫分离塔和带有内部构件的泡沫塔。文章分别综述了各自的作用机理和影响因素的研究进展,提出了可能存在和需要解决的问题。

Foam fractionation technique is one of the important fractionation technologies which has interested more researchers in recent years.Foam fractionation devices are categorized as simple and complex foaming towers according to their different structures.The operation methods of simple foaming towers are categorized as batch operation,semi-batch operation,continuous operation and semi-continuous operation. The complex foaming towers are categorized as multistage foaming towers and foam fractionation devices with the inner components.The operation mechanism and influence factors of each type were reviewed.The existing and possible problems were also presented.
