摘要:
为研究灾变时期井下避难硐室进出口有毒气体CO入侵弥散问题，基于等效原理，利用Gambit软件建立地面钻孔正压通风避难硐室物理模型和开门状态下有毒气体进入避难硐室的流体力学原理及气体弥散数学模型，并利用Fluent软件模拟钻孔压风量与室内CO浓度变化关系，提出在避难硐室的隔离门前加装门衬的办法，使避难人员穿过避难硐室门时空隙面积大大减小。结果表明：加装柔性门衬后临界压风流量分别降至15.7，10.8 m3/min，有效提高了避难硐室防毒安全性。
Abstract:
In order to study the intrusion and dispersion of toxic gas CO at the entrance and exit of underground refuge chamber during the disaster period,based on the equivalence principle,the GAMBIT software was used to establish a physical model of refuge chamber with ground borehole positive pressure ventilation,as well as the hydrodynamic principle and gas dispersion mathematical model of toxic gas entering the refuge chamber under the condition of opening door.The change relationship between borehole pressure airflow and indoor CO concentration was simulated by FLUENT software.The method of adding door lining to the isolation door of refuge chamber was put forward so that the gap area of the refuge personnel passing through the door of refuge chamber was greatly reduced.The results showed that the critical pressure airflow was reduced to 15.7 m3/min and 10.8 m3/min,respectively,which indicated that the installation of the flexible door lining could effectively improve the anti toxic safety of refuge chamber.
