Abstract

The invention provides an electrolysis water hydrogen production device and method. The device includes a power generation system, a hot water recycling system and an electrolysis water hydrogen production system; the power generation system is used to heat water to produce water vapor, and utilizes water The steam generates electricity; the electrolysis water hydrogen production system is used to electrolyze water to produce hydrogen using the electric energy provided by the power generation system; the hot water recycling system is used to circulate and process the hot water after the power generation system generates electricity. Waste heat is recovered, and the recovered waste heat is used to heat the recycled water, and then the heated water is sent to the electrolytic water hydrogen production system for use as electrolyte. The device and method for producing hydrogen by electrolyzing water provided by the present invention can greatly improve the efficiency of producing hydrogen by electrolyzing water.

Description

technical field [0001] The invention relates to a hydrogen production device and method by electrolyzing water, and belongs to the technical field of hydrogen production by electrolyzing water. Background technique [0002] Geothermal energy is a green, low-carbon, renewable energy generated inside the earth, which can be directly used for heating or power generation. In recent years, the world's geothermal power generation has developed rapidly. The geothermal power generation market in the Americas is dominated by the United States, Mexico and Nicaragua, and the installed capacity of geothermal power generation is 3400MW. The geothermal power generation markets in the Asia-Pacific region mainly include Indonesia, Japan, the Philippines and New Zealand, and the installed capacity of geothermal power generation is 4,500MW. In 2014, the global installed capacity of geothermal power generation was 12594MW. China's geothermal resources are abundant and widely distributed, wit...
