摘 要

“十一五”规划明确提出：全面落实科学发展观，建设资源节约型、环境友好型社会，大力发展循环经济，加强资源综合利用，全面推行清洁生产，形成低投入、低消耗、低排放和高效率的节约型增长方式；加大环境保护力度，降低污染物排放，切实保护好自然生态。本设计在遵循这一原则的基础上，结合大量水泥厂的现实数据，对新型干法窑烧成系统进行了初步设计。本文包括总体设计和预分解窑窑尾设计两部分。在总体设计中，主要进行了配料计算，全场物料平衡，主机平衡和储库计算。在车间设计中则包括分解炉和预热器系统热工计算和窑尾工艺设备选型。该设计主要的特点应用了预分解窑。预分解窑是在悬浮预热窑的预热器和回转窑之间增设了一个分解炉作为第二热源，使燃料燃烧的放热过程与生料的碳酸盐分解的吸热过程，在悬浮态或流化态条件下及其迅速地进行，从而减轻了回转窑的热力强度，并使入窑生料的碳酸盐分解率提高到85%-95%，使窑的生产能力成倍增长。

Abstract

“Eleveth Five-year Plan” made clear:the full implementation of the scientific development concept and building a resource-saving and environment-friendly society;vigorously develop the circular economy and strengthen the comprehensive utilization of resources,the full implementatiom of clean production,the formation of low-input,low consumption,low emissions and efficient-saving mode of growth;intensify environmental protection,and reduced pollutant emissions,and effectively protect the natural ecology.In this paper, including the design and pre-kiln back-end design in two parts. In the overall design, the main ingredients for the calculation, the material balance of the audience, the host computing balance and storage. Design in the workshop include preheater and calciner system thermal calculation and back-end process equipment selection. The design of the main features of the application of the pre-kiln. Precalciner kiln is preheated in the suspension preheater kilns and between the addition of a rotary kiln calciner as a second heat source, so that the exothermic fuel combustion process and raw materials endothermic carbonate decomposition process, in the suspended state or fluidization conditions and rapid manner, so as to reduce the heat intensity of the rotary kiln.Raw materials into the kiln and the carbonate decomposition rate to 85 % -95%, so the kiln production capacity doubled.
