加氢站氢气泄漏扩散分析及火气系统优化
Analysis of Hydrogen Leakage and Diffusion and Optimization of Fire and Gas System in Hydrogen Refueling Station
摘要
Abstract
Regarding the current research on hydrogen refueling station detectors,most of it focuses on opti-mizing the collection performance of the detector itself,without quantifying the detection coverage.Using com-putational fluid dynamics to analyze the hydrogen leakage and diffusion behavior of a hydrogen refueling station,combined with scenario analysis method and geographic analysis method,a detector layout study was conducted on the fire and gas system of a comprehensive hydrogen refueling station to comprehensively evaluate the detector coverage of existing fire and gas system.The results showed that there were still some leakage points and target areas within the hydrogen refueling station that cannot be effectively detected by fire and gas system.The cover-age rates of gas detectors at 6 leakage points were 66.7%、50.0%、16.7%、83.3%、66.7%、66.7%,respective-ly,and only one met the requirements.Ultrasonic detectors can be added as an effective supplement to gas de-tectors to cover the entire station.The coverage rates of flame detectors in the 4 target areas were 18.1%、2.4%、0、66.9%,respectively,which did not meet the requirements.By adjusting the angle and position of the existing flame detectors and adding flame detectors,the coverage rate of flame detectors can be increased to over 80%,effectively avoiding further expansion of fire accidents.关键词
