摘　　要：选取一台工业锅炉上配置的蜗壳式旋风分离器,通过等速采样和称重以及压降测量,研究旋风分离器的除尘性能。试验结果表明:随着进口颗粒物浓度提高,旋风分离器对PM_(1)、PM_(1~2.5)、PM_(2.5~10)以及PM_(>10)的除尘效率均提高,且粒径范围越小除尘效率提高的幅度越大,旋风分离器压降单调上升;随着进口颗粒物质量浓度从321 g/m^(3)提高到1675 g/m^(3),除尘效率从89.7%提高到99.0%,其出口颗粒物浓度基本保持不变,仅在较高浓度下出口颗粒物浓度略有下降。A volute type cyclone separator installed on an industrial boiler is selected to study the dust removal performance of the cyclone separator through isokinetic sampling,weighing,and pressure drop measurement.The experimental results show that as the concentration of imported particle increases,the dust removal efficiency of cyclone separator for PM_(1),PM_(1~2.5),PM_(2.5~10),and PM_(>10)all increase;the smaller the particle size range,the greater the improvement in dust removal efficiency;the pressure drop of the cyclone separator increases monotonically.As the concentration of imported particulate matter increases from 321 g/m^(3)to 1675 g/m^(3),the dust removal efficiency increases from 89.7%to 99.0%,and the concentration of outlet particulate matter remains basically unchanged,only slightly decreasing at higher concentrations.
