石油化工厂罐区的防火安全问题一直受到国内外专家的重视,甚至不惜投入大量资金,从设计上、管理上采取各种积极有效的措施和先进技术,防止罐区内火灾事故的发生。在石油化工厂管区内,储存的多是原油,且罐体越来越趋向大型化,通过对国内炼油厂油罐火灾进行调查结果表明,在全部油罐火灾中原油罐占40%,汽油罐(包括污油罐)占32%,柴油罐占8%,重质油品储罐占20%,由此可见,原油罐火灾在油罐火灾中占有相当大的比例,因而对原油罐火灾的危险特性分析的研究迫在眉睫。目前,世界上原油单罐容量已高达24×104m~3,我国最大原油单罐容量也达到15×104m~3;原油具有易挥发、易流失、易燃烧、易爆炸等性质,因此一旦发生火灾,必将造成巨大的人员和财产损失。本文从原油储罐物料及原油燃烧的基本特征两方面研究介绍了原油储罐火灾的危险特征。通过本篇文章的研究,可以使消防部队加深对原油罐火灾的认识了解,为以后此方面的火灾扑救提供一定的参考价值。 相似文献

通过在淮南矿业集团应用通风技术灭火的战例，阐述了在高沼气矿井掘进头发生火灾时，如何通过有计划有安全措施的停止局部扇风机的运转(零点通风)使火灾瓦斯中沼气急剧上升超过爆炸上限，氧气下降到瓦斯爆炸所需要的氧含量下限以下而失去爆炸性，再直接灭火为主要灭火手段来安全、迅速、经济的将火灾扑灭。 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
