摘要
Abstract
A nitrogen explosion suppression method under hydrogen leakage in a limited space of a hydrogen refueling station is proposed,and a numerical model of hydrogen leakage is established to simulate the hydrogen leakage state in a limited space;Simulate and study nitrogen nozzles with different injection angles to find suitable injection angles;A nitrogen explosion suppression device was designed,and simulation was conducted under two conditions:natural diffusion of hydrogen and activation of the nitrogen explosion suppression device after hydrogen leakage.A full-scale test platform was built for on-site verification.The experimental results show that the intervention of nitrogen explosion suppression system can accelerate the reduction rate of hydrogen concentration in a confined space by more than 50%,effectively shortening the duration of hydrogen concentration alarm in the space.The research results can provide some reference for the intrinsic safety protection of hydrogen refueling stations.关键词
