摘　　要：综述了国内外近几年提高旋风分离器捕集粒径5μm以下细粉效率的研究进展。最新的研究试验表明:新的组合式旋风分离器基本上能完全分离粒径1μm左右的微细颗粒,已突破了旋风分离器技术不能有效分离5μm以下微细颗粒的传统观念;促使超细颗粒预团聚的旋风分离器组合分离系统是目前最有应用前景的一种微细颗粒旋风除尘技术,值得进一步研究开发。The current research status of improving the removal efficiency of gas cyclones for particles smaller than 5μm is reviewed. It is shown that a modern cyclone separator can almost completely capture the particles larger than 1 μm when auxiliary devices and/or the conventional mechanisms are integrated with. By exploring the physical fundamentals of fine particle separation,new arid innovative cyclone devices can be developed. Enhancing agglomeration of fine particles before entering a cyclone for them is looked to be a most prospecting way to reduce the emission of fine particles from the cyclone and worthy of further research and development.
