分析造气湿煤灰作为管道输送介质的沉降性能。分析结果为,Wt=20%的单一粒径浆体,粒径越小,悬浮或沉降的时间越长;Wt=20%的造气湿煤灰原样,其悬浮和沉降时间为3 min,介于单一粒径之间,且随着固体颗粒含量的增加,悬浮和沉降所需时间越长。造气湿煤灰单一粒径浆体和原样的SV值变化相似,在固体颗粒含量一定时,随着粒径的变化,SV值不受影响。
Analyze the settling performance of gas-wet coal ash as the pipeline transportation medium. The results show that the smaller the particle size is, the longer the suspension or settling time is for the single size slurry with Wt = 20%; the wetting and settling time of Wt = 20% Between single particle sizes, and as the solids content increases, the longer it takes to suspend and settle. The single particle size of the wet-made wet-ash slurry is similar to that of the original sample. When the solid particle content is constant, the SV value will not be affected as the particle size changes.
