摘要
目前我国城市因土地资源紧张,生活垃圾的主流处理工艺已由填埋向焚烧转变,焚烧处置比例达50%以上,垃圾热值作为垃圾是否可以采用焚烧处理技术的关键因素,对其实现精准分析具有重要意义.利用氧弹量热测量法和元素分析仪分析方法通则,完成了 13 种橡塑类、8 种织物类、18 种纸张类、30 种厨余类以及 8 种木竹类单一成分物质干基高位热值测定及碳、氢、氧、氮、硫、氯元素分析.热值检测实验结果显示,橡塑类、织物类、纸张类、厨余类及木竹类单一成分物质的干基高位热值数据范围分别是 20 790～48 228、16 903～37 854、10 046～16 923、15 704～26 434、16 082～26 932 kJ/kg.研究还发现物质的干基高位热值主要与碳、氢元素的含量呈正相关性,与氧元素含量呈负相关性.
Abstract
Due to the shortage of land resources in China,the mainstream treatment process of domestic waste has changed from landfill to incineration,and the proportion of incineration disposal had reached more than 50%.The accurate analysis of calorific value of waste,as the key factor of whether waste could be incinerated,is of great significance.The dry-base high caloric value determination and C,H,O,N,S,Cl content analysis of thirteen kinds of rubber and plastic,eight kinds of fabrics,eighteen kinds of paper,thirty kinds of kitchen waste and eight kinds of wood and bamboo single components were realized by using bomb calorimetric method and analytical methods of elemental analyzer.The calorific value test results showed that the dry-base high calorific value data scale of rubber and plastic,fabric,paper,kitchen waste and wood and bamboo were 20 790～48 228、16 903～37 854、10 046～16 923、15 704～26 434、16 082～26 932 kJ/kg,respectively.It was also found that the dry-base high caloric value was mainly positively correlated with the content of carbon and hydrogen,and negatively correlated with the content of oxygen.
