A hydrogen replenishment system and method for offshore alloy hydrogen storage and hydrogen supply using heat self-circulation

Abstract

The invention relates to the technical field of hydrogen energy, in particular to a hydrogen replenishment system and method for offshore alloy hydrogen storage and hydrogen supply using heat self-circulation. The replenishment system of the present invention includes an organic liquid storage tank, the discharge port of the organic liquid storage tank is connected to the feed port of the preheater through the infusion pipeline, and the discharge port of the preheater is connected to the feed port of the dehydrogenation reactor through the transfusion pipeline The outlet of the dehydrogenation reactor is connected to the inlet of the gas-liquid separator, the gas outlet on the upper part of the gas-liquid separator is connected to the inlet of the hydrogen purifier through a gas pipeline, and the outlet on the lower part of the gas-liquid separator is connected through an infusion pipeline The feed port of the heat exchanger; the replenishment method of the present invention includes several steps of preparation work, start-up of the circulating cooling unit, hydrogen filling and closing of the replenishment system. The invention can prevent the underwater vehicle from frequently returning to a specific port base for hydrogen supply, and improves the working efficiency of the underwater vehicle.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy, in particular to a hydrogen supply system and method for offshore alloy hydrogen storage and hydrogen supply using heat self-circulation. Background technique [0002] The ocean covers about 70% of the earth's surface area. The development and utilization of ocean resources and the maintenance of ocean rights and interests are inseparable from the development of underwater vehicles such as submarines and UUVs. Underwater endurance is the prerequisite for underwater vehicles to survive and operate for a long time underwater, and the power unit is a key factor that determines the underwater endurance performance of underwater vehicles. [0003] As a new generation of underwater power plant, fuel cell power plant has attracted extensive attention due to its advantages such as high energy conversion efficiency, low noise during operation, no waste emission, low infrared signature, large worki...
