摘要
在分析紧急救援站存在的通风方案的基础上对比不同风机布置方案:安全隧道、疏散横通道内布置风机(原设计);安全隧道内射流送风;疏散横通道内布置风机。得到各风机布置方案保证疏散横通道达到2.0 m/s的时间以及达到的最终风速。得到各风机布置方案皆可以保证疏散横通道防护门处风速达到2.0m/s以上,基本没有烟雾进入安全隧道和横通道;射流风机布置在紧急救援站附近与布置在隧道洞口最大的差别在于疏散横通道风速达到2.0m/s的时间不同;横通道内安装的射流风机实际达不到预计的通风效果,通风效率较低,不推荐采用。
Different layout schemes of fans about emergency rescue station were compared based on the analysis of existing ventilation scheme,which was setting fans in both safety tunnel and evacuation transverse tunnel（original design）,setting jet fans in safety tunnel and setting jet fans in evacuation transverse tunnel.The time of wind speed reaching 2.0m/s and ultimate wind speed of different layout scheme were calculated.The results showed that wind speed at protection door in evacuation transverse tunnel could be guaranteed to 2.0 m/s in each scheme and there was no smoke spread in the safety tunnel and transverse tunnel.The main difference of setting jet fans near emergency rescue station and setting jet fans at tunnel entrance was the time to reach 2.0m/s in evacuation transverse tunnel.The layout scheme of setting jet fans in transverse tunnel could not have expected effect and it was not recommended.
