            摘要:

            介绍了烟草评吸室中工位排风的原理和排风速度的确定及孔板送风的设计计算,通过模拟计算对孔板送风和传统送风的速度场和温度场进行了比较,为定点小浓度污染物的排放提供了思路,同时也为孔板送风设计提供了参考。

            Abstract:

            Presents the principle of workstation exhaust, the determination of exhaust air velocity and the design and calculation of perforated ceiling air supply in a tobacco evaluation room. Compares the velocity and temperature fields between perforated ceiling air supply and traditional air supply by simulation and calculation. Provides the ideas of how to vent the low concentration pollutants and the method for perforated ceiling air supply design.
