摘要:: 储存易燃易爆液化石油气的储罐,必须设置安全泄放系统,同时加设冷却水系统,以防止火灾情况下发生爆炸事故。安全泄放与冷却水系统是二者互相联系的安全措施。液化石油气储罐应设置弹簧封闭全启式安全阀。把国家劳动部《压力容器安全技术监察规程》中安全阀计算公式与《建筑设计防火规范》中的有关内容联系起来,提出了液化石油气储罐安全阀的简化计算公式。对安全阀泄放管的设置提出了以下要求:由于安全阀排放时喷嘴处气速极大,致使管道中气流速度也大,所以排放管道支承应牢固;放空立管应设阻火器和防雷接地;排放系统必须始终保持畅通。

Abstract:: Safety relief and cooling system should be allocated for a storage tank of flamable and explosive LPG so as to prevent explosion when a fire takes place. The said systems are two related safety precautions. LPG storage tanks should be provided with fully-open safety valves which are sealed with springs. The simplified equation for relief valves of LPG storage tanks is got based on the formula sited in "Vessel Safety Technical Inspection Regulation" issued by China National Labor Ministry and also based on the related content of " Fire Protection Specification of Architectural Design". The following requirements are put forward for the allocation of relief tubes for safety valves. The supports of relief tubes should be firm enough because the gas flow speed gets higher in the tubes due to the high gas flow speed at the nozzels when relief valves are in operation. Vent risers should be provided with a flame arresters and lightening protection groundings. The relief system should be kept unblocked all the time.
