摘要
建立了锁气室建压过程的理论模型,分析了污染物稀释过程中乱流稀释公式的适用性,并据此对典型锁气室不同通风量下的通过时间进行计算。通过分析可知,通过时间随通风量增大而减小,计算时可忽略建压过程的耗时。
A theoretical model of the pressing process of an airlock is built up, and the application of the dilution formula for turbulent flow is analyzed during the pollution dilution process. Then, the passage time with different ventilation rate is calculated for a typical airlock. The analysis of the results show that the passage time will reduce with the increasing ventilation rate, and the time of pressing process can be omitted during the calculation.
