摘要
为了预测温度对分离器性能的影响，选用一个直径为300mm的切流反转式旋风分离器在常温～973K的范围内进行了性能试验研究。试验用粉料为二氧化硅，其中位粒径为10μm；入口气速的变化为12～36m／s。试验测定了不同入口气速和温度下旋风分离器的分离效率与压降。结果表明，相同人口气速下，分离效率与压降均随温度的升高而降低。当气速达到最佳入口气速时，旋风分离器的分离效率最高，且最佳入口气速随温度的增加而增加。
In order to predict the influence of operating temperatures on cyclone performance, an experimental investigation was conducted on particle separation in a reverse flow, tangential volute-inlet cyclone separator, which has a diameter of 300 mm, with air heated up to 973 K. The test powder silica has a mass median diameter of 10 μm and the inlet velocity ranges from 12 to 36 m/s. Both the separation efficiency and pressure drop of the cyclone were measured as a function of the inlet velocity and operating temperature, It is shown that at the same inlet velocity, both the separation efficiency and pressure drop decrease with the increase of temperature. Besides, the optimum inlet velocity, at which the cyclone has a highest separation efficiency, tends to increase with the rise of temperature.
