Cement raw material compatibility method and system for cement kiln to co-process solid waste
The invention discloses a cement raw material compatibility method and system for co-processing solid wastes in a cement kiln, which is characterized in that solid waste ash is taken as a cement raw material to be blended into cement raw material, and a cement raw material blending method is improved and optimized. On the basis of online analysis of calorific values of mineral components and combustible components of cement raw materials, energy conservation in the cement raw materials and balance of four main mineral components are set as constraint equation conditions, and a cement raw material optimal proportioning scheme of the maximum solid waste doping amount is verified through three rate value indexes (KH +/-0.02, SM +/-0.1 and IM +/-0.1). According to the method, more solid wastes can be mixed and burnt in the cement kiln on the premise that the cement quality is not affected, and the problems that in the co-processing process of an existing cement kiln, the energy consumption of a system is high, the mixing amount of the solid wastes is small, the components of the solid wastes are different, and the cement quality is unstable are solved.
本发明公布了一种水泥窑协同处置固体废物的水泥生料配伍方法和系统，将固体废物灰渣作为水泥原料参入水泥生料配料，改进和优化水泥生料配料方法。基于水泥原料矿物组分及可燃组分热值在线分析，设置水泥生料中能量守恒及4种主要矿物组分平衡作为约束方程条件，通过三率值指标(KH±0.02、SM±0.1、IM±0.1)验证最大固体废物掺入量的水泥生料优化配料方案，获得基于最大固体废物掺入量的水泥生料优化配料方法，该方法能够在不影响水泥质量前提下水泥窑掺烧的更多的固体废物，解决了现有水泥窑协同处置过程系统能耗较高、固体废物掺入量小、固体废物组分差异水泥品质不稳定等问题。
