本文主要研究内容
作者路长,王鸿波,张运鹏,朱寒,余明高（2019）在《氮气幕对瓦斯爆炸进行阻爆实验》一文中研究指出：为阻断瓦斯爆炸在管道方向上的传播,保护管道后方区域,本文采用氮气幕来进行阻爆,所设计的实验装置在爆炸发生后能自动喷出氮气。主要研究了氮气的喷气压力和喷气时刻对阻爆功能的影响。结果表明,在喷气压力为0.1MPa时,氮气幕仅起到抑制作用,爆炸火焰能穿过整个实验管道。在喷气压力为0.2MPa时,仅部分实验能够阻爆,氮气幕产生不稳定的阻爆效果。在喷气压力为0.3MPa时,阻爆位置均稳定在左喷头和右喷头之间区域,氮气幕产生稳定地阻爆效果。喷气压力超过0.4MPa后,阻爆位置稳定在右喷头附近。在较低氮气压力0.2MPa下,喷气时刻对阻爆效果产生显著影响。随着喷气时刻延迟,氮气喷出量减小,氮气幕由不稳定阻爆变为不阻爆。喷气时刻延迟到198ms后,氮气幕便丧失阻爆功能。在喷气压力超过0.3MPa后,氮气幕阻爆效果便不受喷气时刻的影响,喷气压力对能否阻爆起决定作用。
