一、引言 随着我国四化建设的发展,对液化石油气的需求量不断增长。贮罐和罐区的建设,在全国大中城市发展很快,规模日趋大型化。贮罐区的消防,安全问题越来越为人民所重视。 液化石油气贮罐区一旦发生火灾,如不及时采取措施,后果往往是十分严重的。引起严重后果的原因,一般是由于贮罐受热爆炸,导致灾害升级,形成恶性火灾而造成的。为了防止火灾中的贮罐遭到破坏,除应对火灾进行控制,积极设法消除气体泄漏以外,喷水冷却对处于火灾威胁下的贮罐,目前仍是世界上保护贮罐免遭破坏,扼制灾害升级的基本手段。
I. INTRODUCTION With the development of the four modernizations in our country, the demand for liquefied petroleum gas is on the rise. The construction of storage tanks and tank farms has developed rapidly in large and medium-sized cities across the country and has become increasingly large-scale. The firefighting and safety problems in the storage area have been paid more and more attention by the people. In the event of a fire in a liquefied petroleum gas storage tank area, if the measures are not taken promptly, the consequences will often be very serious. The causes of serious consequences are generally caused by the explosion of storage tanks which lead to the escalation of disasters and the formation of a vicious fire. In order to prevent damage to the storage tanks during fires, in addition to controlling the fires and actively seeking to eliminate gas leaks, water-jet cooling storage tanks under the threat of fire are still the world’s safeguards to protect storage tanks from damage and contain hazards The basic means of upgrading.
