For the natural resist degradation barrier of lignocellulosic materials,attempts were made to move away the lignin to raise the conversion rate of cellulose and
针对长桨短叶片复合搅拌桨(LSB),从功率消耗、混合时间和流型三个角度,研究了其在流体混合过程的性能特性。首先对搅拌桨在釜内的功率消耗进行了测量,考察搅拌桨的结构参数、搅拌桨的安装高度、挡板的安装距离和操作条件等对功率消耗的影响。研究发现,在相同转速下,随着液面高度的增大,单位体积功率消耗相应的增大；在相同液面高度下,随着转速的增大,单位体积功率消耗呈指数增大。固定长桨：长桨LB-1,外环β=0°
