Safety protection system and method of hydrogen fuel cell ship

Abstract

The invention provides a safety protection system and method of a hydrogen fuel cell ship. The safety protection system comprises a hydrogen leakage monitoring alarm module, an emergency switching-offmodule, a ventilation module, an automatic extinguishing module and a monitoring station. The safety and the reliability of the hydrogen fuel cell are improved in the ship application by the real-time monitoring of the concentration of the hydrogen, the early leakage warning, the concentration control, the automatic extinguishing function and the manual extinguishing function; thus, the possibility of hydrogen fuel cell accident is reduced to the utmost extent; and, the staff safety and the property safety on the ship are ensured. The grading chain alarm control method can get the chain alarmgrading information of the cabin precisely, timely and reliably; the super early cabin leakage information alarm saves precious time for cutting off the hydrogen supply and taking ventilation measures; single cabin alarms; each adjacent cabin pre-alarms; the single area alarms; the adjacent areas are separated; thus, the hydrogen is prevented from leaking and spreading; and, the whole ship chainleakage and the fire explosion accident are prevented.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel cell ship safety protection, and in particular relates to a hydrogen fuel cell ship safety protection system and protection method. Background technique [0002] With the gradual aggravation of environmental pollution and energy shortage, in the field of transportation, ships consume a lot of energy, and their emissions are also serious environmental pollution. Especially for coastal and inland river and lake ships, the requirements for emissions are becoming more and more stringent. In recent years, green ships and new energy technologies have developed rapidly, and green ship technology using hydrogen as fuel has become one of the main directions for the development of the ship industry. As a joint product of the development of hydrogen energy technology and green ship technology, hydrogen fuel cell ships have the advantages of green environmental protection, high efficiency, high energy d...

AI Technical Summary

Problems solved by technology

[0003] Because today's fuel cell and battery management technology is not mature enough, and the safety of hydrogen fuel cell itself is lower than that of traditional diesel engine as the main engine of a ship

The hydrogen fuel cell stack is generally placed in the fuel cell compartment, and hydrogen gas leakage may occur during the working process. Hydrogen gas is flammable, and when it reaches a certain concentration, it may cause fire and explosion

Especially when ships encounter sudden accidents such as collisions and shipwrecks, fuel cells are likely to cause safety accidents such as hydrogen leakage, fire and explosion.

The working environment of the ship is on the water, and the working environment is more harsh and changeable. There are many factors that cause fuel cell safety accidents, and it is relatively difficult to implement the corresponding rescue measures in case of an accident.
