鼓风式风选机在城市垃圾分类中的应用

Application of Blast Air Separator in Urban Waste Classification

近些年来,随着城市建设的高速发展,我国城市生活垃圾在产生量剧增的同时,关于城市生活垃圾处理的问题也越来越多。通过相关数据分析并阐述了我国城市生活垃圾的特点,说明了城市生活垃圾的危害,提出了城市生活垃圾合理化处理的重要性。分选技术是城市垃圾减量化、资源化和无害化处理的关键性技术之一,可回收利用的物质如果不能经过分选前处理将其分离,将影响后续回收的操作,降低其回收利用的可行性。对垃圾分类所用到的分选技术中的风力分选的原理进行了描述。同时着重介绍了鼓风式风选机的工作原理和结构,以及鼓风式风选机在城市垃圾分选的相关应用和特点。

In recent years,with the rapid development of urban construction,the amount of municipal solid waste in China has increased sharply.At the same time,there are more and more problems about the treatment of municipal solid waste.The characteristics of urban domestic waste in China were analyzed and expounded,the harm of urban domestic waste was explained,and the importance of rational treatment of urban domestic waste was put forward.Separation technology is one of the key technologies for the reduction,recycling and harmless treatment of urban waste,because if the recyclable substances can not be separated after pre-treatment,it will affect the subsequent recovery operation and reduce the feasibility of recycling.The principle of wind separation in the separation technology used in waste classification was described.At the same time,the working principle and structure of blast air separator,as well as the related application and characteristics of blast air separator in urban waste separation were introduced.
