微波加热处置飞灰技术具有高效、节能、清洁等优点,虽然目前已经有了一些实验研究,但仍存在缺少大型工业化设备、难以实现大规模、连续处理应用等技术性问题.本文简述了垃圾焚烧飞灰的处置现状以及微波特性和加热机理.综合近年来的微波应用情况,介绍了微波处置飞灰的机理和应用进展,并将处置方法分为微波水热浸取、微波水热固化、微波烧结以及微波氧化脱除二英等四大类进行分别阐述,分析了这几种处置方式可以达到的应用效果、存在的优缺点以及和传统的飞灰处置方式的成本对比.最后指出了要实现微波大规模应用,必须攻克设备工业化难关,提出了必须继续深入微波在飞灰处置领域研究的建议,从而实现微波处置工艺系统化、工业化.

Using microwave heating to dispose of fly ash has been studied by researchers,considering its advantages of high efficiency,energy saving and cleanliness. However,due to lack of large-scale industrial equipment,large-scale application of microwave technology is limited. In this paper,current situation of disposal of municipal solid waste (MSW) fly ash and the special properties and heating mechanism of microwave are reviewed. Based on microwave application in recent years,the mechanism of microwave disposal is discussed. The disposal methods using microwave are also summarized,including microwave extraction,microwave hydrothermal,microwave sintering and microwave oxidation to remove dioxins. The application effects and the advantages and disadvantages of the four disposal methods are analyzed. Besides,the costs of the four disposal methods are also compared with the traditional one. In the end,to realize application of microwave in large-scale disposal,the difficulties of industrialization of equipment must be resolved,and microwave technology in the field of fly ash disposal has to be studied further.
