摘要
针对舰船火灾难以处置的特点,为解决机械通风控制烟气的问题,基于某舰船机舱搭建实验模型,通过改变补风口高度位置以及补风量大小,针对不同工况,定量分析机舱火灾温度、O_2、CO、CO_2体积分数,研究机械通风配置对于舰船火灾烟气控制效果的影响。实验结果表明,通过改变补风口高度位置、补风量大小、单双侧补风等参数,可优化舰船机舱烟气控制效果。
In the ship,fire is difficult to dispose.In order to solve the problem of mechanical ventilation control flue gas,an experimental model was built based on the cabin of a certain type of ship.By changing the height position of the air inlet and the amount of air supply,the cabin fire temperature,volume fraction of O\-2,CO and CO\-2were quantitatively analyzed for different working conditions,so as to study the effect of mechanical ventilation configuration on the smoke control effect of ship fire.The experimental results showed that the smoke control effect of the ship cabin can be optimized by changing the height position of the vent,the amount of air supply and the parameters of the single and double sides.
