液化烃球罐的消防设计

The Fire Protection Design of Liquefied Hydrocarbon Spherical Tank

通过分析液化烃的组成和着火特点,阐述液化烃球罐发生火灾时的消防冷却方式及系统组成,并根据自己的设计经历,以容积为3000 m3的球罐为例,从水雾喷头水雾锥的保护面积入手,估算出冷却装置所需要的喷头数量和水量,反向核算整个冷却系统的经济性和合理性。

Through the analysis of the composition and fire characteristics of liquefied hydrocarbon,the fire control cooling method and system of liquefied hydrocarbon spherical tank were described.According to the design experience,taking the spherical tank of 3000 m3 as an example,starting from the protection area of water spray cone,the number of nozzles and water quantity of the cooling device was estimated,and the economy and rationality of the entire cooling system was back calculated.
