【摘要】：垃圾是城市发展的附属物,同城市和人类一起运转。一边是不断增长的城市垃圾,一边是无法忍受的恶臭,城市生活垃圾处理已经成为非常棘手的问题。我国高速发展的城市,大多都正在遭遇“垃圾围城”之痛。如何处理这些生活垃圾是亟待解决的一个问题。本论文分析和比较了各种处理生活垃圾的方法,并在前期废塑料热裂解的实验装置基础上研究改进和开发了一套利用热裂解技术处理生活垃圾,得到气体和液态烃类燃料的工业化装置,该实验装置和方法已获国家知识产权局授予发明专利。所设计的工业化装置创新地使用低熔点盐熔液作为热载体对生活垃圾进行热裂解,而且实现了连续进料,避免了热裂解过程中的传热不均匀也大大提高了热裂解的处理效率。本文设计的工业化装置可以对混合生活垃圾进行热裂解回收,无需进行垃圾分类,更加适合大规模推广,从而有效地解决目前日益严重的生活垃圾污染环境的问题,变废为宝,具有非常广阔的发展前景。
[Abstract]:Garbage is an adjunct to the development of a city, running with the city and human beings. With growing urban waste and an intolerable stench, the disposal of urban domestic waste has become a thorny problem. China's rapid development of cities, most are suffering from "garbage siege" pain. How to deal with these domestic wastes is an urgent problem to be solved. In this paper, the methods of treating domestic waste are analyzed and compared, and based on the experimental device of pyrolysis of waste plastics, a set of treatment methods using pyrolysis technology is developed. An industrial device for obtaining gaseous and liquid hydrocarbon fuels, which has been patented by the State intellectual property Office. The designed industrial device innovatively uses low melting point salt molten liquid as heat carrier to pyrolysis domestic refuse, and realizes continuous feed, which avoids heat transfer inhomogeneity in pyrolysis process and greatly improves the efficiency of pyrolysis treatment. The industrial device designed in this paper can be used for pyrolysis and recovery of mixed domestic waste without waste classification, so it is more suitable for large-scale promotion, thus effectively solving the problem of increasingly serious environmental pollution caused by domestic waste and turning waste into treasure. It has very broad prospects for development.
