摘　　要：环吸式排风罩是针对铝压延加工工艺油雾散发特征而提出的一种高效捕集设备,可以大幅降低系统风量,从而减少能耗和降低碳排放量,但目前仍缺乏此类排风罩的通用设计方法。本文选取10个铝压延车间铝冷轧机及排风罩为研究对象,探究了不同轧机尺寸组合下排风罩罩口处污染物扩散断面尺寸和排风罩捕集性能,通过回归分析得到了排风罩罩口设计尺寸和设计风量的计算方法,可供工程设计人员参考。The ring suction exhaust hood is a high-efficiency capture equipment proposed for the oil mist emission characteristics of the aluminum rolling processing technology,which can greatly reduce the air volume of the system,thereby reducing the energy consumption and carbon emissions.However,there is still a lack of common design methods for this exhaust hood.In this paper,ten aluminum cold rolling mills and exhaust hoods in aluminum rolling workshops are selected as research objects,and the size of pollutant diffusion cross-section at the exhaust hood opening and the capture performance of the exhaust hoods under different rolling mill size combinations are studied.Through regression analysis,the calculation method of the design size of the exhaust hood opening and the design air volume is obtained,which can be used as a reference for engineering designers.
