摘　　要：考虑到煤尘水分低(含水1%～4%)、粒度小的特点,先利用压缩氮气为动力源实施浓相气力输送,再采用组合成型技术,即高压干粉处理工艺和低压型煤生产工艺融合,实现了煤尘的资源化高效清洁回用。Because the coal dust has lower moisture and smaller size,we used compressed N 2 to realize the dense-phase transportation of coal dust in the first step.We used the dust as resource by assembling forming process including high pressure dry powder process and low pressure section process.The technique is a higher effective and cleaner technique and the effect is better.

关 键 词：煤尘 浓相气力输送 组合成型 高效清洁回用
