摘要： 为了研究采用二氧化碳灭火系统时陶坛酒库火灾后事故排风系统的设计参数，依照现行规范的要求，计算了某陶坛酒库采用二氧化碳系统灭火后排风系统的通风换气次数、环境风速和排风口参数，利用PHAST软件计算了在3种模拟工况下，二氧化碳排放后在下风方向的气体体积分数分布范围。结果表明，当酒库的换气次数为12次/h时，建议排风口的风速为14.0 m/s，排风口面积为0.13 m2，且排风口应设置在距离地面高度2.1 m以上，并与重点场所的最小距离不小于6.4 m。研究结果可为陶坛酒库采用二氧化碳灭火系统时的事故排风系统设计提供数据支撑，并为酒库火灾的灭火救援安全提供参考。

Abstract: To study the design parameters of the exhaust air system for CO2 fire extinguishing in Taotan wine warehouse, according to the current national standards, the ventilation frequency, environmental wind speed, and exhaust parameters of the exhaust system after carbon dioxide fire extinguishing in a certain pottery wine cellar were calculated. The gas volume fraction distribution in the downwind direction after carbon dioxide emission was calculated using PHSAT software under three simulated operating conditions. According to the calculation results, when the air exchange rate of the wine cellar is 12 times/h, it is recommended that the wind speed of the exhaust outlet be 14.0 m/s, the exhaust outlet area be 0.13 m2, and the height of the exhaust outlet should be set at a distance of 2.1 m or more from the ground, with a minimum distance of not less than 6.4 m from key areas. The research results can provide effective data support for the design of exhaust systems after carbon dioxide fire extinguishing in wine warehouses, and provide reference for the rescue of wine warehouse fires.
