Research on Ventilation System Regulation and Ventilation Quality of Heyi Mine
In order to solve the problems of constant air supply,loss of air volume and low ventilation efficiency of the original ventilation system,this paper takes the time wheel algorithm combined with frequency converter to control the fan rate as the research object.According to the different air volume required in different periods of underground operation,the fan rate is rationally regulated to make the air volume match the actual production.This paper takes Heyi Mine as an example,according to the actual required air volume,the corresponding speed of the fan is calculated,and the air supply is carried out in different periods.The system has achieved the expected effect,ensured the ventilation quality,and achieved the purpose of energy saving.
