【摘要】：在我国经济快速发展的同时,垃圾数量逐年增加,垃圾包围城市的问题越来越突显,对生活环境造成的危害也越来越严重。由于垃圾传统的填埋、堆肥和焚烧等处理方法很难满足大量城市生活垃圾处理时日益严格环保要求,而且垃圾的传统处理技术对垃圾能量利用率很低并且处理不够彻底。利用新型干法水泥窑协同处理技术不但可彻底处理生活垃圾、有效解决环境污染,并且能为水泥生产提供燃料和原料,进一步提高了能量的利用效率,是现代垃圾处理的研究和发展方向。本论文深入分析了我国的城市生活垃圾处理现状,以及国内外垃圾处理技术的进展,通过研究垃圾焚烧对水泥窑生产系统和水泥熟料性能及对生态环境的影响,分析了利用新型水泥干法窑协同处置城市生活垃圾的可能性。并结合企业实际的水泥窑协同处置城市生活垃圾项目,设计了多套方案进行优化筛选,得出使用“炉排炉+水泥窑”协同处置是较为理想的方案,可以有效的实现生活垃圾处理“减量化、无害化、资源化”的目的,具有良好的示范和推广意义。
[Abstract]:With the rapid development of economy in China, the amount of garbage increases year by year, the problem of garbage surrounding the city is more and more prominent, and the harm to the living environment is becoming more and more serious. Because of the traditional landfill, composting and incineration methods, it is difficult to meet the increasingly stringent environmental protection requirements of a large number of municipal solid waste treatment, and the traditional garbage treatment technology is very low energy utilization and disposal is not enough. Using the new dry cement kiln cooperative treatment technology can not only thoroughly deal with domestic waste, but also effectively solve the environmental pollution, and can provide fuel and raw materials for cement production, and further improve the efficiency of energy utilization. It is the research and development direction of modern waste disposal. In this paper, the present situation of municipal solid waste treatment in China and the development of domestic and foreign garbage disposal technology are analyzed. The effects of MSW incineration on cement kiln production system, cement clinker performance and ecological environment are studied. The possibility of co-disposal of municipal solid waste with new cement dry kiln is analyzed. Combined with the actual cement kiln cooperative disposal of municipal solid waste project, several sets of schemes are designed to optimize the selection, and it is concluded that using "grate furnace cement kiln" cooperative disposal is a more ideal scheme. It can effectively realize the goal of reducing quantity, innocuous and resource utilization, and has good demonstration and popularization significance.
