摘　　要：为切实提升氢气探测系统的实际探测有效性和覆盖率,提出1种点式氢气探测器的网格化布局方法,通过泄漏场景库构建、探测器布置网格点划分、CFD仿真与数据处理等步骤建立布局优化数学模型,使用贪心算法进行迭代求解,以某企业氢气纯化装置为案例构建点式氢气探测器布局优化数学模型并求解。研究结果表明:仅新增8台氢气探测器即可将该装置的场景覆盖率从29.46%提升至80.81%,新增氢气探测器的安装位置同样符合GB/T 50493—2019的要求。研究结果可为涉氢装置的氢气探测器布局设计提供指导。In order to improve the detection effectiveness and coverage of the hydrogen detection system,a grid layout method of point-mode hydrogen detectors was proposed.A mathematical model for layout optimization was established through the steps of leakage scenario library construction,detector layout grid division,CFD simulation and data processing.The greedy algorithm was used to solve the mathematical model iteratively.Taking the hydrogen purification device of an enterprise as an example,the mathematical model for the layout optimization of point-mode hydrogen detectors was constructed and solved.The results show that only adding 8 hydrogen detectors can increase the scenario coverage of the device from 29.46%to 80.81%.The installation location of the new added hydrogen detectors also complies with the requirements of GB/T 50493—2019.The research results can provide guidance for the layout design of hydrogen detectors for hydrogen-related devices.
