摘　　要：声波团聚技术在细颗粒物排放控制领域具有很好的应用前景,最近衍生发展为一种全新的火灾烟雾控制手段。该文对声波团聚技术发展现状进行全面总结,介绍近年的实验和理论研究进展。随后,阐述了声波团聚消烟的基本原理,并以火灾烟雾中占比较大的电缆燃烧烟雾为实验对象,发现声波团聚技术在1min后就实现对电缆燃烧烟雾的完全消除,即存在突出的团聚效果。该结果验证了该技术在火灾烟雾控制领域的可行性。最后,依托我国城市发展现状,探讨了声波团聚技术在火灾消烟的发展前景。Acoustic agglomeration technology is a promising method for fine PM emission control.Recently,it has been used for fast smoke elimination in fire scenarios by our group for the first time.In this paper,the history and development of acoustic agglomeration technology are summarized and the basic principles of smoke elimination utilizing acoustic agglomeration technology are described in details.In addition,an experimental study of fire smoke control from electric cables has been conducted to understand the behavior of light transmittance.Results show that the acoustic agglomeration technology can completely eliminate the cable burning smoke in only 1 min,which confirms the feasibility of this technology.Finally,the challenges and prospect of acoustic agglomeration technology in the field of fire smoke elimination are discussed.
