摘要
总结了煤颗粒的物理化学特性(孔结构、表面特征、粒度分布、密度等)以及水质(组分、添加剂种类及用量等)对浆体特性(浓度、流变性、粘度特性、稳定性等)影响的研究进展;从煤炭清洁加工利用与现代煤化工发展需求角度,分析了水煤浆技术发展的趋势,指出了废水制浆过程中的先进技术与装备是重点研究方向,探讨了水煤浆理论和实践中存在的技术瓶颈,分析了水煤浆技术的研究方向和发展路线。
The research progress of influences of particle physicochemical properties,such as porous structure, surface characteristics,particle size distribution,density,and water quality,such as components,types and amounts of additives,on slurry properties including concentration,rheology,viscosity characteristics,stability,etc.,are summarized. From the perspective of coal clean processing utilization and modern coal chemical development demand,the development trend of coal water slurry technology,and it is pointed out that,advanced technology and equipment of the wastewater CWS preparation is a key research direction. The technical bottlenecks in CWS preparing theory and practice are discussed, and the research direction and development route of CWS technology is analyzed.
