中国生活垃圾气化处理技术的应用

Application of Solid Waste Gasification Technology in China

随着中国经济快速发展,社会物质水平和居民生活质量显著提高,生活垃圾总产量逐渐增加。生活垃圾气化技术能够实现生活垃圾减量化、资源化、无害化处理,受到一定的关注,但在国内鲜有实际应用的项目。文章介绍了生活垃圾气化处理技术的发展历程和技术原理与工艺配置,分析对比国内外的生活垃圾气化技术案例,指出通过垃圾分类、垃圾预处理及掺混生活垃圾的方法,提高垃圾热值,以利于生活垃圾气化设备的稳定运行。此外,提高生活垃圾气化设备处理规模,抑制污染物生成将是未来研究的重点。

A gradually increasing of domestic wastes was displayed,caused by a significant improvement of the social material level and citizens’ living quality,with the economy boosting in China.Gasification technologies which could achieve reduction,recovery and harmlessness maintained a certain degree of concern but less application in China.In this paper,the development history,technical theories and process configurations of the gasification disposal technologies of household wastes were introduced,and the application prospect in China through case study contrast of the international projects and domestic projects was analyzed.It was pointed out that by waste separation,pretreatment and mixing with other fuels,heat value could increase,contributing to the operation stability.In addition,amplifying household waste gasification system scale and controlling formation of by-product pollutants would be concerned in future studies.
