【摘要】：采用歐拉模型與k-ε湍流模型,利用ANSYS軟件中的Fluent模塊分析反應器內部的流體特性,計算攪拌器的驅動扭矩與功率;應用流-固耦合理論,利用Static Structural模塊計算攪拌軸及槳的應力與撓度。結果表明:單跨與懸臂約束方式的攪拌器內部流體特性一致,采用2種約束方式的攪拌軸及槳的應力最大值點位置相同,均在上層六直葉圓盤渦輪的槳葉與圓盤連接處,其中單跨、懸臂約束方式的攪拌軸及槳的最大應力值分別為22.37、26.44 MPa;采用單跨約束的主軸、攪拌槳應力最大值分別為懸臂約束的62%、84.6%;采用單跨約束的攪拌軸及槳的撓度最大值點在上層槳槳葉末梢,懸臂約束的在下層槳槳葉的末梢,其中單跨約束的攪拌軸及槳的變形量最大值為0.45 mm,懸臂約束的為1.67 mm;采用單跨約束的主軸、攪拌槳變形分別為懸臂約束的10.7%、26.9%。
[Abstract]:Using Euler model and k- 蔚 turbulence model, using Fluent module in ANSYS software to analyze the fluid characteristics of reactor, calculate the driving torque and power of agitator, apply the theory of fluid-solid coupling, The stress and deflection of stirring shaft and propeller are calculated by Static Structural module. The results show that the internal fluid characteristics of the agitator with single span and cantilever confinement are the same, and the maximum stress points of the agitator shaft and propeller with two kinds of restraint modes are the same, and they are all located at the connection between the blade and the disk of the upper six-blade disk turbine. The maximum stress values of single span, cantilever restraint shaft and propeller are 22.37 ~ 26.44 MPa respectively. The maximum stress of the impeller is 62um 84.6with cantilever constraint, the maximum deflection of the impeller with single span constraint is at the end of the upper propeller blade, and the tip of the lower propeller blade with cantilever constraint is at the end of the lower propeller blade, the maximum deflection of the impeller is at the end of the upper propeller blade. The maximum deformation of single-span impeller and agitator is 0.45 mm and that of cantilever is 1.67 mm, and that of single span restraint is 10.7% and 26.9mm, respectively.
