基于风量可调度的矿井风量调节

Adjustment of mine air volume based on air volume dispatchable model

  • 摘要: 由于通风网络中分支的风量相互影响,针对改变分支风阻重新分配风量的方法会造成风量减小较快的分支风量不能满足最低需风要求的问题,基于风量调节基本理论建立了风量可调度模型,提出了基于风量可调度的矿井风量调节方法。该方法利用风网解算确定被调分支风阻可调范围,进而从定量角度求得需风分支风量可调度。利用该方法计算风量可调度便于选择最佳风阻调节分支以及确定风阻调节范围与风量变化量。

     

    Abstract: Due to the air volume of branch of ventilation network is influenced by each other, and the method of change branch wind resistance to airflow distribution will be caused the air volume of decreased faster branch airflow cannot meet the minimum requirements, the air volume dispatchable model was set up based on airflow condition theory, an adjustment method of air volume based on air volume dispatchable model was proposed. The adjustment method uses ventilation network solution to calculate adjustable range of branch wind resistance, and obtains the air volume of branch from quantitative angle. Using the method to calculate air volume is convenient to choose the most adjustable branch and confirm the wind resistance adjustment range and variation of air quantity.
