Abstract

The invention aims to provide a parallel gas-electric hybrid power system based on a fuel cell. The system comprises a propeller, a natural gas engine, a reversible motor and a propeller connecting gear box, an exhaust pipe of the natural gas engine is respectively connected with a heat exchange reforming heat supply pipe, a natural vent pipe and a fuel cell heat supply pipe, and the heat exchangereforming heat supply pipe is connected with a heat exchange reformer. The fuel cell heat supply pipe is connected with the fuel cell, the natural vent pipe is communicated with a pipeline behind thefuel cell and then connected with a turbine of the turbocharger, a gas compressor of the turbocharger is connected with a mixer, an LNG tank is connected with the mixer, and the mixer is connected with the natural gas engine. Fuel reforming and fuel cell heating can be reasonably utilized to generate power, switching of different modes is achieved through valve control by combining with a parallel hybrid power system so as to adapt to different navigation working conditions, and the hybrid power system has the advantages of being high in efficiency, high in adaptability, good in dynamic response and the like.

Description

technical field [0001] The invention relates to a power device, in particular to a ship power device. Background technique [0002] The main pollution produced by the shipbuilding industry is exhaust gas pollution, oil pollution and pollution caused by domestic sewage. Among them, ship exhaust pollution is the most serious, especially in the offshore area. The speed of the ship is relatively slow, and the engine cannot operate in the high-working condition area, and its pollutant discharge is much higher than the level of normal operation. It has brought great inconvenience. [0003] Faced with such a serious problem of air pollution, the ship industry has also made timely changes. At present, there are many new forms of ship power, such as pure electric transmission, solar ships, wind energy ships, and LNG ships. LNG ships powered by natural gas engines have good prospects for development. However, limited by the current technology, natural gas engines fueled by natural ...
