Adopting Screw Impeller Agitator to increase Efficiency of Methane Fermentor 采用螺旋桨搅拌器增加沼气发酵池效率
With the variety of the impeller tip angle from 17.6 to 23, the surface stress of the agitator blade is increased. 在叶端安放角βt从17.6°到23°时,随着叶端安放角的增加,桨叶表面的应力也在增加。
The form and dimension scaling relation of the optimized hooked disc impeller and hooked narrow impeller as well as the power number of agitator and correction factor of power number in case of complete baffle under turbulence have been presented. 介绍了优化后的带钩圆盘桨和带钩窄叶桨的形状、尺寸比例关系和在湍流状态下全挡板时的搅拌功率准数和功率准数修正系数。
