Abstract

The invention provides an integrated water purification electrolytic hydrogen production system which comprises a cooling water supply system, a water electrolysis hydrogen production system, a solar purification system and a heat regulation system which are connected end to end through pipelines, and the solar purification system introduces purified water into the water electrolysis hydrogen production system for liquid supplementation; unpurified water in the cooling water supply system is subjected to heat exchange through the water electrolysis hydrogen production system and is introduced into the solar purification system, the solar purification system of the system uses heated circulating water as a water source, cooling water is purified through solar energy, generated water can be directly input into the water electrolysis hydrogen production system to be subjected to an electrolytic reaction, and the hydrogen production efficiency is improved. The water purification and electrolysis hydrogen production integrated method improves the purification efficiency, reduces the energy consumption, is energy-saving and environment-friendly, provides green and environment-friendly hydrogen energy for the country, and also provides guarantee for the energy safety of the country.

Description

technical field [0001] The present application relates to the technical field of electrolytic hydrogen production, in particular to an integrated water purification electrolytic hydrogen production system. Background technique [0002] Hydrogen production by electrolysis of water is a commonly used hydrogen production method in industry. It uses water as raw material and electrolyzes pure water into hydrogen and oxygen in an alkaline environment. In order to ensure the purity of hydrogen and avoid the generation of chlorine and other impurity gases during the electrolysis process, water often needs to be purified in multiple steps before it is passed into the electrolytic cell. The most commonly used water purification technology is reverse osmosis membrane desalination. This technology has high processing efficiency, simple device and easy maintenance, and has been popularized to a certain extent. However, the material cost of reverse osmosis membrane required by this me...
