摘要
为解决朔中选煤厂煤泥贮运、燃用十分困难及价格低廉、难于销售的问题,采用MGT3420滚筒式煤泥干燥系统对其进行干燥提质。介绍了MGT3420滚筒式煤泥干燥系统的结构、工作原理、技术特点及技术参数,并分析了该系统的应用效果。生产实践表明:采用MGT3420滚筒式煤泥干燥系统对该厂煤泥干燥提质后,煤泥水分由原来的24%降至现在的16%,发热量由原来的15.06 MJ/kg提高到现在的17.15 MJ/kg,满足贮运及与商品煤混配销售的要求,经济效益和社会效益显著。
In order to solve the problems of difficult of storage,transportation and burning,as well as low price and difficult to sales of coal slime in Shuozhong coal preparation plant,using the MGT3420 drum drying system to drying and upgrading coal slime.The paper introduced the structure,working principle,technical features and parameters of MGT3420 drum drying system,and analyzed the application effect of the system.The production practice shows that with adopting MGT3420 drum slime drying system for drying and upgrading,the moisture of slime decreased from 24% to the 16%,calorific value increased from 15.06 MJ / kg to 17.15 MJ / kg now,which meet the requirements of storage and blended as commercial coal sales,also obtained good economic and social benefits.
