| 摘 要： | 热重气体是指从容器、管道、钻井等喷出时的温度比大气环境温度高、标准状况下密度比空气密度大的气体.有毒热重气体沉降到地面会对人和动植物造成危害.本文根据能量守恒定律和气体状态方程,建立了静风环境热重气体行为模式判别式,计算分析了喷出气体温度不同、有毒热重气体含量不同时的有毒热重气体行为模式.计算结果分析表明,随着喷出气体温度的升高,空气与有毒热重气体混合物中有毒热重气体开始沉降的浓度下降.

| Abstract: | Hot- weighty gas erupts from container, pipeline and well - drilling, and its temperature is higher than atmospheric temperature and density is thicker than air in standard condition. The noxious hot - weighty gas subsiding to ground will be harm to human and plants. This text is based on the law of conversation of energy and state equation of gas to set up discriminants of behavior mode of hot - weighty gas in the state of static breeze. The results of calculating and analyzing this mode under the condition of the mixture gas erupts in different temperature and content of noxious hot- weighty gas indicates that with the temperature of eruptinggas rising, the subsidence - initial density of noxious hot - weighty gas mixed with air will reduce. |
