High pressure hydrogen supply system for hydrogen fuel cell ships

Abstract

The invention discloses a hydrogen fuel cell ship high-pressure hydrogen supply system, which comprises a hydrogen supply pipeline, a hydrogen vent pipeline and a hydrogen filling pipeline. The hydrogen supply line comprises three communicating first hydrogen cylinders, a second hydrogen cylinder and a third hydrogen cylinder, the first hydrogen cylinder is connected with a fuel cell power generation system through a supply pipe; The supply pipe is provided with a bottle mouth combination valve; The hydrogen bleeding pipeline is connected with the bottle mouth combination valve through a bleeding pipe, the first branch of the bleeding pipe is provided with a bleeding valve, and the bleeding valve is connected with the first manual valve through the pipeline; The second branch of the emptying pipe is provided with a safety valve, and the safety valve is connected with the fourth manual valve through a pipeline. The third branch of the emptying pipe is provided with a flame arrester; Thehydrogen filling pipeline is connected with the bottle mouth combination valve through a filling pipe, and the filling pipe is provided with a fourth solenoid valve, a filter, a third pressure gauge,a one-way valve and a filling port. The invention can provide reliable hydrogen fuel supply for ships.

Description

technical field

[0001] The invention relates to the technical field of fuel supply for new energy ships, in particular to a hydrogen fuel cell ship high-pressure hydrogen supply system. Background technique

[0002] In recent years, the green ship technology using hydrogen as fuel has become one of the main development directions of the ship industry. As a joint product of the development of hydrogen energy technology and green ship technology, fuel cell ships have the advantages of low emissions, high efficiency, high energy density, good stability, and low noise. Great potential.

[0003] However, due to the large hydrogen storage capacity of the hydrogen system in the hydrogen fuel cell ship, the hydrogen supply pipeline is complicated, and the cabin is closed. Once hydrogen leakage occurs, it is easy to cause fire and explosion. This is a passenger ship with high density of personnel and difficult water rescue. , the security risks of which cannot be ignored. Therefor...
