【摘要】 在已开发的流化床、振动流化床干燥器的基础上 ,提出并实现了物料S型流动的固定流化床工艺 ,研制开发了S型流动连续式固定流化床干燥器 ,应用于氯化聚乙烯 (CPE)滤饼的干燥 ,取得了成功突破 ;就CPE的干燥特点、连续式固定流化床干燥器的特点进行了分析 ,得到CPE流化床干燥的最佳工艺参数 :流化速度为 0 .8～ 1 .0m/s,流化板的开孔率为 4%～ 9% ,4个室的干燥温度分别为 1 2 5、1 1 5、80、70℃更多还原

【Abstract】 Based on past research and development of pneumatic dryer and vibro fluidized bed dryer, the fixed fluidized bed is put out nowadays in which materials can be moved in S shape. This equipment has been successfully used to dry CPE. The drying characteristics of CPE and fixed fluidized bed dryer are introduced. The best operation parameters of CPE drying in S shape fixed fluidized bed dryer are obtained. These are in the following: the fluidized velocity is 0.8～1.0 m/s, the area of the opening holes on the distribution board is 4%～9% , the drying temperatures in four sections of the drying chambers are 125 ℃?115 ℃?80 ℃?70 ℃.更多还原
