Distributed type power generation and hydrogen generation system based on sewage treatment plant

Abstract

A distributed type power generation and hydrogen generation system based on a sewage treatment plant comprises a regenerated water storage device which is connected with a regenerated water output pipeline of a sewage treatment plant, a pure water preparing device which is connected with the regenerated water storage device, a wind power generation device, a solar power generation device, a wind-solar complementary control device which is connected with the wind power generation device and the solar power generation device, a DC-DC converting device which is connected with the wind-solar complementary control device, an electrolysis water hydrogen production device which is connected with the DC-DC converting device to conduct the electrolysis water hydrogen production reaction to form nitrogen and oxygen, a pure water preparing device which is connected with the electrolysis water hydrogen production device, a hydrogen purification device which is connected with the electrolysis waterhydrogen production device, a hydrogen storage device which is connected with the hydrogen purification device and used for storing purified hydrogen, and an oxygen storage device which is connectedwith the electrolysis water hydrogen production device and used for storing oxygen. Hydrogen is generated through reclaimed water in the sewage treatment plant, the reclaimed water in the sewage treatment plant is sufficiently utilized, the sewage treatment plant becomes a hydrogen generation station and an oxygen generation station, and the high price of the hydrogen is lowered.

Description

technical field [0001] This application relates to the technical field of hydrogen production from renewable resources, in particular to a distributed power generation hydrogen production system based on a sewage treatment plant. Background technique [0002] Hydrogen is an important industrial raw material, as well as an important industrial gas and special gas. It is widely used in petrochemical, electronic industry, metallurgical industry, fine chemical industry, organic synthesis, aerospace, new energy vehicles and other fields. In recent years, with the rapid development of hydrogen fuel cells, optoelectronics, metallurgy, semiconductor and other industries, the demand for high-purity hydrogen has increased rapidly, which has promoted people's research on large-scale hydrogen production technology. At present, the large-scale production technologies of hydrogen mainly include hydrogen production from coal chemical industry, hydrogen production from natural gas, hydrogen...

AI Technical Summary

Problems solved by technology

The above-mentioned hydrogen production methods have their own advantages and disadvantages. Among them, the water electrolysis hydrogen production technology has high hydrogen purity, mature technology, and small device volume, which is very suitable for the production of high-purity hydrogen on a small and medium scale. Larger consumption of industrial electricity leads to higher price of product hydrogen
