褐煤干燥脱水技术的研究进展

介绍了褐煤的现状以及褐煤利用过程中存在的问题,提出了几种褐煤脱水工艺,如回转管式干燥技术,蒸汽流化床干燥技术、热机械脱水(MTE)等,并分析了各自的特点,最后对MTE工艺机理进行了初步探讨。 This paper first introduced the present status of lignite and the problem in the process of lignite used,and then proposed several lignite dehydration technologies,such as the rotary tube drying,steam fluidized bed dry technology,thermo-mechanical dehydration(MTE),at last go into the mechanism of the MTE technology
