摘　　要：蒸汽煤泥干燥系统排气为80~85℃的高湿气体,是优质的余热资源。若将其中热量回收,建成依托于蒸汽干燥系统的余热回收型煤泥干燥系统,可提高能源利用效率,增加产能。进行低温煤泥干燥实验,结果表明,60℃热空气煤泥干燥表现良好,证明本系统的可行性。依托于某煤矿洗煤厂蒸汽回转煤泥干燥系统,设计热管式余热回收煤泥干燥系统,为煤炭行业节能减排提供新的方法。The steam slime drying system is a high humidity gas of 80~85℃,which is a high quality waste heat resource.If the heat is recovered and the waste heat recovery slime drying system based on the steam drying system is built,the energy efficiency can be improved and the production capacity can be increased.The experiment of low temperature slime drying is carried out,and the results show that the performance of hot air slime drying at 60℃is good,which proves the feasibility of the system.Based on the steam rotary slime drying system of a coal mine washing plant,a heat pipe waste heat recovery slime drying system is designed,which provides a new method for energy saving and emission reduction in the coal industry.
