PAGE PAGE l 5000t/d水泥熟料预分解窑窑尾（低氮氧化合物排放）工艺设计 摘要：水泥是社会经济发展最重要的建筑材料之一，在今后几十年甚至是上百年之内仍然是无可替代的基础材料，对人类生活文明的重要性不言而喻。 以预分解窑为代表的新型干法水泥生产技术已经成为当今水泥工业发展的主导技术和最先进的工艺，它具有生产能力大、自动化程度高、产品质量高、能耗低、有害物排放量低等一系列优点。 但在水泥生产过程中会放出一些有害物质，尤其是氮氧化合物，按照要求本设计采用一系列的方法，以求降低氮氧化合物的排放浓度。本设计依据当今新型干法水泥生产技术的设计要求进行，主要任务是窑尾部分的工艺设计，包括新型干法水泥生产对原料、燃料的质量要求，配料方案的设计和配料计算，物料平衡计算，主辅机平衡与设备选型，储库计算和窑尾工艺设计。 关键词：5000t/d； 预分解窑； 低氮排放； 工艺设计 The Process Design of the Back End of Precalciner Kiln for 5000T/D Cement Clinker(Low Nitrogen Oxide Emissions) Abstract:Cement is one of the most important building materials of the social and economic development, within the coming decades or even a century,Cement is still no substitute for basic materials, the importance of human civilization is self-evident. calciner kiln as the representatives has become leading technology and the most advanced technology of the cement industry. It has many advantages, such as high throughput, a high degree of auto mation, high quality products, low energy consumption, low emissions of harmful substances, etc. In the production process of cement will release a number of harmful substances,particularly nitrogen oxides,according to the requirement of this design,the design uses a range of methods to reduce the concentration of nitrogen oxide .Based on the design of new dry cement production technology in todays design requirements, the main task is the back-end part of the process design, including the production of cement raw materials, fuel quality requirements, the design of ingredients and ingredients, the material balance calculation , the main auxiliary balance and equipment selection, calculation and storage back-end process design.
