摘要
本文对区域可控循环通风技术进行研究,根据巷道风速、瓦斯浓度、粉尘浓度、风机消耗功率和循环区域新鲜供风量来确定循环风机的最优循环率,用以对实际生产循环风机进行合理选择和运用。
In this paper, the area controllable circulation ventilation had been studied, according to the request of the tunnel air speed, gas density and the dust concentration, the air fan consumed power and the fresh air quantity of recirculation area to pick up the optimal recirculation rate, then choose the reasonable recirculation fan to use.
