摘要
结合某型号旋风除尘器的结构参数,建立除尘效率数学模型。通过MATLAB进行最优化求解,利用计算流体力学方法对优化后的模型进行除尘效率验证。结果表明:当筒体直径为328.0mm、总高度为1287.5mm、排气管直径为195.1mm、插入深度为246.2mm、入口高度为131.3mm、宽度为65.6mm、筒体高度为656.5mm时,总除尘效率最高且最大值为97.1%;采用MATLAB最优化计算及CFD数值模拟相结合的方法,克服了单纯实验周期长、费用高等缺点,对旋风除尘器最优化设计具有重要的工程应用价值。
Combined with the structural parameters of a certain type of cyclone dust collector,the mathematical model was established,and the optimization solution was carried out by using MATLAB,and the dust removal efficiency was calculated by using the CFD method. The results show that when the diameter of tube is 328.0 mm,the total height is 1287.5 mm,the diameter of exhaust pipe is 195.1 mm,and the insertion depth is 246.2 mm. the inlet height is 131.3 mm,the width is 65.6 mm,and the cylinder height is 656.5 mm,the total dust removal efficiency is the highest and the maximum value is 97.1 mm. By combining optimization algorithm with simulation numerical simulation,this paper overcomes the shortcoming of high cost of simple experiment cycle and has important engineering application value.
