一、建筑物爆炸泄压防护技术的局限性 建筑物爆炸泄压是近年来随着化学工业不断发展,爆炸事故时有发生而发展起来的一种防护技术。它的实质就是在含有可燃气(或可燃粉尘)的建筑物内开一定面积的门、窗或者设计一些薄弱构件(如可泄放的轻质墙、轻质屋顶),万一建筑物内发生可燃气(或可燃粉尘)爆燃,这些薄弱构件首先“爆破”,形成泄压口,末燃的可燃气以及燃烧产物从泄压口排出,大部分可燃气在建筑物外燃烧,从而使建筑物内的压力不至于升得过高,保证了建筑物主结构件的安全,减少了人员伤亡。
First, the limitations of building explosion pressure relief technology Building explosion relief is in recent years as the chemical industry continues to develop, the explosion occurred from time to time and developed a protective technology. Its essence is to open a certain area of the door or window in the building containing combustible gas (or combustible dust) or to design some weak components (such as light-weight walls and light roofs that can be drained) Combustible gas (or combustible dust) deflagration, the first of these weak components “blasting” to form a pressure relief port, the combustible gas combustion and combustion products from the vent, the majority of combustible gas burning outside the building, so that buildings The pressure inside will not rise too high to ensure the safety of the main structure of the building and reduce the casualties.
