摘要 基于海上某平台原排烟设计方案中存在的问题,进行了排烟设计方案优化。采用CFD软件对优化后平台高温烟气扩散及不同环境条件的运行工况进行了模拟仿真,分析了烟气温度及有害气体浓度的分布范围,结合CAP 437规范及人体接触有害气体限值,计算了温度升高导致直升机起降的不可使用概率和有害气体浓度危害程度及概率,最后探讨了缓解高温烟气危害的措施及排烟设计建议。本文研究结果可为海上平台高温排烟设计提供参考依据。 The smoke exhaust scheme was optimized to solve the problems in the original design of an off- shore platform. CFD software is used to analyze the distribution and temperature of the high temperature exhausted gas based on the optimized design, including the combined conditions of the hot exhaust diffu- sion and different wind directions. The probability of endangering the helicopter takes off and landing and the poisonous gas impact were calculated considering the gas temperature rise and the poisonous gas con- centration according to CAP 437 and the limits of human exposure to the harmful gas. Finally the mitiga- ting measures against the high temperature exhausted gas were analyzed and the suggestions for the ex- haust design put forward on the base of the aforementioned simulation. The research work here offers a reference for the high temperature exhausted gas design for other offshore platforms.
