Research on Optimized Design and Practical Application of Coal Mine Ventilator Impeller
Based on the numerical simulation method,the impeller structure of G4-73No.8D centrifugal ventilator is optimized.Based on the overview of the overall structure of the centrifugal ventilator,the numerical simulation model of the ventilator is constructed by using FLUENT software,and the simulation results are compared with the practical results,and it is found that the model has a very good accuracy.The blade outlet installation angle and the number of blades n are taken as the optimization objects,and the optimization results are 44.5° and 14 pieces.Comparative study of the performance of the equipment before and after optimization by numerical simulation and industrial practice methods found that the performance of the equipment has been greatly improved,in which the ventilation capacity has been increased by 33.42％.This optimization and improvement work meets the expectation and can create certain economic benefits for the enterprise.
