摘要
针对５０～６ｍｍ级入选原煤特点和干燥要求，提出了振动穿流床干燥新方法，结合试验结果，对该方法的干燥机理进行了详细的理论分析．研究表明该方法具有快速干燥、均匀干燥及物料升温吸热少的优点，仅需６ｓ左右即可使煤样外在水降低到１％以下．过干燥和欠干燥物料很少，有效地提高了热能利用率．
Aiming at the characteristics of raw coal with a particle size of 50￣6mm and its drying requirements, a new drying method named hot gas penetrating vibration bed drying is put forward and a detailed theoretical analysis of drying mechanism of this method is presented on the basis of experimental results. It is proven that the method is characterized by fast drying (only 6 seconds are needed to reduce the water content to less than 1%), homogeneous drying (few over dried or under dried coal), and less heat absorption.
