摘要:
加气站压缩机间安全设计时，需要评估内部气体爆炸危害，确定爆炸能量和影响因素。采用CFD技术，建立加气站压缩机间三维模型，模拟不同点火源位置、泄压板不同泄压压力和重量下，压缩机间气体爆炸时的爆炸压力及火焰传播行为。结果表明点火源位置以及泄压参数是影响加气站压缩机间气体爆炸的重要因素；点火源位置距离压缩机间放空位置越近，爆炸压力越小；对于泄压参数，爆炸压力与泄压板开启压力和重量之间均为正比关系。为减缓压缩机间内的气体爆炸危害，需要合理布置点火源位置，选择容重轻、泄压压力小的泄压材料，并同时需要考虑爆炸导致的物体破碎危害以及火焰次生灾害。
Abstract:
The hazards of gas explosion in compression compartment should be assessed, and explosion energy as well as influence factors should be determined for the safety design of compression compartment in gas filling station. In this study, numerical simulation was adopted to build 3D model of compression compartment and simulate gas explosion pressure and flame propagation behavior under different ignition point location ,openpressure and weight of relief panels. The results showed that the ignition point location relative to the location of the vent opening and relief panel’s characteristics is very important for gas explosion in compression compartment. The nearer the ignition point location is away from the venting opening location, the smaller the caused explosion pressure will be. For the relief panel, explosion pressure is proportional with the openpressure and the weight of relief panel. Besides the rational distribution of ignition source and the adoption of relief panel with less unit weight and relief pressure, the crushing material damage and secondary hazard of flame should also be noticed in order to mitigate the hazard of gas explosion.
