摘要:
在温度分别为15 ℃、200 ℃、400 ℃、600 ℃、800 ℃，固气质量比分别为0.5、1.0、1.5、2.0、2.5，风速分别为14 m/s、16 m/s、18 m/s、20 m/s、22 m/s、24 m/s的不同条件下，试验研究温度、固气比和风速对旋风预热器分级分离效率的影响，结果表明：物料颗粒直径dp≤1μm时，分级分离效率很高；临界粒径随着风速的提高而减小，随着固气比的增加而减小；临界粒径随着温度的升高逐渐增大，400～600℃时达到高点，随着温度的继续升高临界粒径反而变小．
Abstract:
At different conditions such as temperature of 15℃,200℃,400℃,600℃ and 800℃;solid-gas mass ratio of 0.5,1.0,1.5,2.0 and 2.5;gas velocity of 14m/s,16m/s,18m/s,20m/s,22 m/s and 24 m/s, the influences on fractional collection efficiency were studied. The results show that fractional collection efficiency is high for the particle diameter of less than 1μm; critical size decreases with 天the increase of the gas velocity or the solid-gas mass ratio; critical size increases gradually with the increase of temperature; On reaching a maximum between 400℃~600℃ it decreases gradually as temperature further increases
