Based on a two - dimension model for the flow field in catalytic converter , the flow field and pressure loss in catalytic converter with different inlet headers are simulated 摘要利用催化轉化器流場的二維模型對多種入口管結構的催化轉化器流動分布和壓力損失進行了數值計算,并提出一種組合型入口管。
Hot air cnters into stirring and crushing and drying chamber from the bottom of drier with suitable atomizing speed . it exerts strong shearing , blowing , floating and rotating effect to raw material . therefore raw material is granulated through centrifuge , shearing , impacting and friction effect 熱空氣由入口管以適宜的進風速度從干燥機底部旋轉進入攪拌粉碎干燥室,對物料產生強烈的剪切、吹浮、旋轉作用。
The experimental and simulation results show that using the improved structure of inlet header can greatly improve flow uniformity , decrease pressure loss , enhance the efficiency of twc , attribute to prolonging the service life of the machine , and lessen the power decrease caused by twc , but the light - off time of twc is retarded 通過模擬與試驗表明,與常規結構催化轉化器相比,組合型入口管可明顯改善流動均勻性,降低壓力損失約1 / 4 ,提高催化轉化器效率,延長使用壽命,減小對發動機動力性的影響,但起燃變慢。
