回转窑简体温度红外扫描与状态预报系统研究

针对烧结法生产氧化铝工艺过程中回转窑窑皮形状复杂与筒体测温难的特点，采用红外线测温与数字滤波补偿技术相结合，开发出回转窑筒体温度红外线扫描和状态预报系统孩系统在测量回转窑筒体表面温度及其变化的基础上，通过基于模糊协方差矩阵的聚类算法。在线仿真出窑内村与窑皮的形状及厚度，发出相应的状态预报信号，有效地改善了窑的操作，提高了设备的运转率，降低了生产成本，并为回转窑的自动控制提供参考．图2，参12．

The Study on Rotary Kiln Shell Temperature Infrared Ray Scanning and Condition Forecasting System

In the process of using sintering technique of rotary kiln to produce alumina, the shape of kiln crust is complex and the temperature measurement is difficuhy. In order to solve these two problems, an infrared ray scanning and condition forecasting system of rotary kiln is introduced, which uses infrared ray temporature measurement and digital filter compensating. Based on the value and change rate of kiln shell surface temperature, the shape and thickness of kiln crust and lining can be simulated and the corresponding signal of condition forecasting can give off by a clustering algorithm of fuzzy covariance matrix. The system improves the operation of kiln effectively, enhances the operation rate of facilities, reduces the cost of production and provides references for automatic control of rotary kiln. 2figs., 12refs.
