Description
Technical Field
The utility model relates to the field of hydrogen production by water electrolysis, in particular to a seawater hydrogen production device.
Background
With the increasing consumption of fossil fuel, the reserves are increasingly reduced, and the resources are exhausted in the last day, so that a new hydrogen production energy source which does not depend on fossil fuel and is rich in reserves is urgently needed to be searched, and the hydrogen production scheme with one of the most market prospects is water electrolysis hydrogen production.
At present, there are two types of water electrolysis to obtain hydrogen energy:
The method is to directly utilize fresh water resources such as river water, lake water and the like in nature to carry out electrolytic hydrogen production, and the report issued by WMO on global water resource status shows that the fresh water resources on the earth only account for 2.53 percent of the total water quantity, wherein 68.7 percent of the fresh water resources belong to solid glaciers, only 1 percent of the fresh water resources can be directly utilized, and about 0.026 percent of the fresh water resources belong to places where the fresh water is buried in the ground. Fresh water reserves only account for 2.53% of the total global water, and are distributed in mountain and north and south polar regions which are difficult to use. The fresh water which can be directly utilized by human beings accounts for only 0.3 percent of the total fresh water. Thus, fresh water resource hydrogen production faces the problem of water resource shortage.
The other is hydrogen production by seawater, wherein the seawater accounts for 96.5% of the total water content of the earth, and the seawater is very complex in composition and contains more than 90 chemical substances and elements unlike fresh water. The large amount of ions, microorganisms, particles and the like contained in the seawater can cause problems of side reaction competition, catalyst deactivation, membrane blockage and the like in the process of preparing hydrogen.
In order to produce hydrogen by using seawater, the current most mature technical route is to produce hydrogen by desalting the seawater and then electrolyzing the seawater by establishing a desalting treatment system at a coastline, and to establish a seawater desalting plant at the coast, thereby greatly improving the cost in the aspects of construction, operation, manpower, maintenance and the like; and the in-situ integrated ocean green hydrogen production system is difficult to be formed by large-scale utilization of offshore wind power coupling, and the stable storage of renewable energy sources, the construction of a multi-energy complementary energy source system and an offshore energy ecological floating island are difficult to realize. The technology seriously depends on large-scale desalting equipment, has complex process flow and occupies a large amount of land resources, and further increases the hydrogen production cost and the engineering construction difficulty.
The existing seawater hydrogen production technology is a seawater desalination-free in-situ direct electrolytic hydrogen production method, wherein seawater passes through a solution mass transfer layer, the solution mass transfer layer blocks solid impurities in the seawater, the physical state of liquid, gas and liquid of the seawater is changed to pass through the solution mass transfer layer, ion impurities in the solution mass transfer layer are filtered, and then the solution mass transfer layer and electrolyte in an electrolytic tank form electrolyte to carry out electrolysis in an ion exchange mode, so that hydrogen and oxygen are generated.
The solution mass transfer layer is used for filtering impurities and ions in seawater, the efficiency is extremely low, the residue in filtered water is relatively large, and the water quality is poor. And the ion precipitation or marine microorganism growth barrier layer is easy to scale and block, which seriously affects the service life of the equipment.
Electrolyte and filtered water are used in the electrolytic tank to form electrolyte for electrolysis, K 2CO3、KOH、NaOH、Ca(OH)2、Na2CO3 and the like are used as electrolyte in the prior art, the electrolyte is alkaline or acidic, and corrosion equipment reduces service life of the equipment and increases cost.
The hydrogen generated by electrolysis of the acidic or alkaline electrolyte has a large amount of residual alkaline or acidic gas, and the process difficulty is increased by secondary purification.
