锌钡白回转窑消色力波动性的成因分析
|
摘要
为寻找某锌钡白回转窑过程的关键质量指标——消色力不稳定的原因,对消色力指标的序列进行了研究.首先用傅立叶方法进行分析,发现其包含的谐波分量比较显著,表明消色力波动存在一定的周期性.为得到关于波动的更详细信息,并考虑消色力序列的非平稳特性,进一步采用希尔伯特-黄变换时频联合分析的方法,通过对其边际谱的研究得到比较精确的波动频率,并由Hilbert谱的分析实现对该波动的时间定位,最后结合实际指出产生该波动的管理和工艺上的原因,从而为质量问题的追溯提供了线索和条件.
As a key performance index of lithopone calcination,the achromic power in a rotary kiln process is fluctuant.In order to ascertain the reasons for the fluctuation,a data series of the achromic power is analyzed.In the investigation,first,strong harmonics in the power signal are revealed via Fourier transform(FT),which means that there is a certain periodicity of the achromic power fluctuation.Next,in order to find out the details of the fluctuation and deal with the non-stationarity,Hilbert-Huang transform(HHT) is used to analyze the marginal spectrum and spatial time-frequency distribution of the signal.Then,by the analysis of Hilbert spectrum,the time and duration of the fluctuation are obtained.Finally,on the basis of practical data,the reasons for the fluctuation are pointed out from the viewpoints of management and technique,thus helping to trace the quality accidents.
