    摘要:

    為了解決擺式磨機存在高能耗、風(fēng)道積料和局部磨損等問(wèn)題,對現有進(jìn)氣風(fēng)道(蝸殼和風(fēng)道葉片)結構設計方案進(jìn)行研究第步。基于流體動(dòng)力學(xué)與多相流及離散元耦合仿真技術(shù),進(jìn)行擺式磨機的內部風(fēng)場(chǎng)與顆粒場(chǎng)的數值模擬。進(jìn)行蝸殼線(xiàn)型、風(fēng)道葉片角度和葉片數量的響應面仿真試驗,結果表明優(yōu)化蝸殼線(xiàn)型有利于降低壓損和設備能耗企亮,合理選擇葉片角度和葉片數量有利于降低風(fēng)道的不均勻系數進(jìn)而調控流場(chǎng)沐刷。基于壓損和不均勻系數的多目標優(yōu)化,確定風(fēng)道結構的最優(yōu)方案:蝸殼2,葉片數量18片、葉片角度55°页亏。優(yōu)化方案的成品收集效率高達95.3%,比企業(yè)原方案提高13.4%。仿真結果與現場(chǎng)實(shí)驗數據的一致性較好,可以為擺式磨機的優(yōu)化與節能設計提供指導。

    Abstract:

    In order to solve the problems of high energy consumption, air duct accumulation and local wear of pendulum mill, the structural design scheme of air inlet duct (including volute and air duct blade) was studied. Based on coupling simulation techniques of fluid dynamics, multiphase flow and discrete element, Numerical simulation of the internal wind field and particle field of the pendulum mill were carried out. The response surface simulation tests of volute profile, blade Angle and blade number were also performed. The results show that optimizing volute profile is beneficial to reducing pressure loss and equipment energy consumption, and reasonable selection of blade angle and blade number is beneficial to reducing the non-uniform coefficient of air duct and regulating flow field. Based on the multi-objective optimization of pressure loss and non-uniformity coefficient, the optimal scheme of air duct structure is determined as: volute 2, blade number 18, blade angle 55°. The finished product collection efficiency of the optimized scheme is 95.3%, which is 13.4% higher than that of the original scheme. The simulation results are in good agreement with the field experimental data, which can provide guidance for the optimization and energy-saving design of pendulum mill.
