机械-自然交替通风系统中平衡风门的应用研究

Research on Application of Balance Air Door in Mechanical-natural Alternative Ventilation System

结合某黄金矿山通风系统的改造课题 ,分析了机械 -自然交替通风系统中平衡风门的工作原理 ,研究了门扇的受力状况。同时 ,通过理论分析导出了平衡风门的设计公式。对于合理应用机械 -自然交替通风系统 ,节能降耗具有实际意义。改造后 ,该黄金矿山全年完全利用自然通风的时间可达 6个月以上。

In combination with the project of the ventilation system transformation, the working principle of the balance air door in the mechanical-natural alternative ventilation system and the stress of the door were studied. Meanwhile, the formula for the balance air door design was deduced by theoretical analysis. It is of practical significance to the rational application of the mechanical-natural ventilation system and the energy saving and consumption reduction. After the transformation, the annual fully natural ventilation time of this mine can be over six months.
