The invention relates to a hydrogen pipeline system. The hydrogen pipeline system involves a two-position three-way electromagnetic valve, a first hydrogen pipeline, a second hydrogen pipeline, a protective cover, a hydrogen sensor and a control circuit; and the first hydrogen pipeline and the second hydrogen pipeline communicate with a hydrogen tank through the two-position three-way electromagnetic valve, connector structures are arranged on the protective cover in a covering mode, and the hydrogen sensor is used for detecting the concentration of hydrogen in the protective cover and generating a detection signal. When hydrogen leakage occurs in the connector structures, the control circuit controls the two-position three-way electromagnetic valve to act according to the detection signal, so that a first inlet communicates with a second outlet; when hydrogen leakage occurs in the first hydrogen pipeline, the hydrogen pipeline system conveys the hydrogen through the second hydrogen pipeline, and a leakage source is blocked, so that continuous hydrogen leakage is avoided; and the hydrogen pipeline system improves the safety of the hydrogen pipelines, furthermore, the protective cover prevents the hydrogen from leaking to the external space so that the hydrogen sensor can conveniently detect leaked hydrogen in time, and the detection sensitivity is improved.
Description
technical field [0001] This application relates to the field of new energy technology, in particular to a hydrogen pipeline system. Background technique [0002] Energy depletion and environmental pollution caused by fossil energy consumption are becoming increasingly serious, and large-scale development and utilization of renewable energy is imperative. Although renewable energy reserves are abundant and widely distributed, they fluctuate violently, especially due to periodic changes due to the influence of the natural environment. Hydrogen is an effective energy storage method: during the peak period of renewable energy power generation, electrical energy is converted into chemical energy and stored in hydrogen, and the energy carried by hydrogen is converted into electrical energy through fuel cells for use during the peak period of electricity consumption. Therefore, technologies such as hydrogen preparation, storage, and transportation have attracted the attention of r...
