The invention discloses a hydrogen leakage preventing device for a marine fuel cell system, comprising a protective part, a nitrogen injection mechanism, a pressure detection part, a hydrogen concentration detection part and a vacuum pumping mechanism; the protective part has a device for accommodating a marine fuel cell system The protective cavity; the beneficial effect of the present invention is: the protective part is set on the marine fuel cell system, and nitrogen is injected into the protective part through the nitrogen gas injection mechanism, so that all hydrogen-related parts of the marine fuel cell system can be inerted. , to reduce the risk of hydrogen accumulation. At the same time, the gas pressure in the protective chamber is continuously detected by the pressure detection part, and the hydrogen concentration in the protective chamber is continuously detected by the hydrogen concentration detection part, so that the marine fuel cell can be detected by the pressure detection part and the hydrogen concentration detection part. Whether hydrogen leakage occurs in the system, when hydrogen leakage is detected, the gas in the protective chamber is pumped out through the vacuum mechanism and discharged into the atmosphere to prevent accidents caused by hydrogen accumulation.
Description
Technical field [0001] The present invention relates to the field of ship safety technology, and more particularly to a hydrogen-free leap device for a marine fuel cell system. Background technique [0002] With the continuous improvement of marine environmental protection, the environmental protection laws and regulations related to ship emissions pollution have been introduced. "Green Shipping" and "Green Ships" environmental energy saving concept has become an important criterion for marine product design and key elements of occupying the ship market. [0003] Traditional ship power units such as diesel engine, steam turbine, gas turbine produce power, low energy conversion efficiency, high vibration noise, pollution gas emissions, etc., can not meet the new social economy development requirements, using high energy density and Renewable energy is the important development direction of future green ships as a power source. [0004] Hydrogen fuel cells are highly dynamic energy...
