生活垃圾破碎特征及其粒度对分析结果的影响

对生活垃圾中4种富含热值的废物进行了研究,结果表明:不同的废物由于物理性质的差异,要达到分析所需要的粒度,应选择不同的破碎设备;纸类废物破碎粒度大小对化学分析结果影响不大;随着破碎粒度的增加,纺织品类废物灰分、热值、氯的含量呈增加趋势,硬塑料灰分、氯的含量减小,而热值呈增加趋势,薄膜塑料灰分减小、热值增加、氯含量变化没有规律。

The Crushing Characteristics of the Municipal Solid Waste and Influence of the Size on Analyzing Result

This research based on 4 kinds of waste riched in calorific value in municipal solid waste indicates,in order to get the size needed for analyzing in laboratory,the different crushing equipment should been choosed for that there is difference in physical quality in different waste;the different crushing size in paper waste has no large effect on chemical analyzing result, with the increasing of the crushing size,there is increasing tendency for the ash content,calorific value and the chlorine content in textile waste,the ash content,chlorine content is decreasing while the calorific value is increasing in hard plastic waste,and the ash content is decreasing,calorific value is increasing,while the chlorine content is changing irregularly in plastic film.
