摘要
以四海煤样为研究对象,利用反渗透浓水和自来水分别制备水煤浆。实验结果表明,在水煤浆添加剂作用下,使用浓水和自来水均可制得质量分数≥58%、黏度≤1 200 m Pa·s的水煤浆,水煤浆稳定性较好,72 h析水率≤7%且没有硬沉淀产生,水煤浆p H和粒度分布均达到技术指标要求。
The coal-water slurry is prepared with Sihai coal sample by using reverse osmosis concentrated water and tap water separately. The resuhs show that in the presence of the additives, reverse osmosis concentrated water and tap water can both produce the coal-water slurry with the concentration higher than 58% and the viscosity ≤ 1200 mPa's. This coal-water slurry has good stability. There is no hard sediment and the water segregation rate is ≤7% after 72 hours. The pH value and particle size distribution of the obtained coal-water slurry both meet the requirements of technical indicators.
