Description
Technical field
The present invention relates to field of hydrogen generation, more particularly to electrolytic hydrogen production and thermal power plant's flexibility Peak Shaving.
Background technology
In recent years, it is rich in Chinese three northern areas of China electricity market capacity, combustion engine, water-storage etc. can peaking power source it is rare,
It is particularly thorny between peak load regulation network and fired power generating unit flexibility, power network dissolve the new energy such as wind-powered electricity generation, photoelectricity and nuclear power ability not
Foot, wind-abandoning phenomenon is serious.Cogeneration units " electricity determining by heat " mode is run, and peak modulation capacity is only 10% or so.Peak regulation is difficult
Through as distinct issues the most in operation of power networks.The transformation of country's thermoelectricity flexibility peak regulation is directed to Winter heat supply unit at present,
Summer, how peak regulation was a problem of the pendulum in face of numerous thermal power plants.In order to meet peaking demand of power grid, and power plant is swashing
Living necessities in strong competition, depth peak regulation is imperative.
China's hydrogen annual production at present has exceeded ten million ton of scale, occupies the first in the world.Plant-scale hydrogen production process is main
Including methane steam reforming and water electrolysis hydrogen production, the yield of wherein water electrolysis hydrogen production accounts for world's hydrogen total output 4%.Although first
Alkane steam reformation is hydrogen production process most economical at present, but it not only consumes a large amount of fossil fuels, and production in process of production
Raw great amount of carbon dioxide.Electrolysis hydrogen producing process process is simple, and product purity is high, comes by using regenerative resource as energy
Source, can show the efficient of hydrogen, cleaning, extensive preparation, the technology can be used for CO2 emission reduction and conversion, with more wide
Wealthy development prospect.Particularly the applicable fuel cell car of hydrogen is can uniquely to reach the ring of automotive performance index comprehensively
Vehicle is protected, maximum social effect is that instead of the Battery disposal and pollution problem of oil and conventional lithium battery automobile, hydrogen fuel cell
The advantage of automobile is really a lot, due to being truly realized pernicious gas zero-emission, more than oil electric mixed dynamic, natural gas, ethanol,
The environment protectings such as biodiesel are preferably；Because fuel cell car with electrolysis water replaces oil, cost is low, resource is wide, contribute to
Overcome oil crisis；From science and technology, find and make being electrically separated in hydrogen using proton membrane, be nuisanceless generating
Significant achievement.

Make.The main energy consumption of electrolytic hydrogen production is electric energy, and every cubic metre of hydrogen power consumption is about 4.5~5.5kWh, and the electricity charge account for whole electrolysis system
80% or so of hydrogen production cost.Therefore, water electrolysis hydrogen production technology is particularly suitable for use in the renewable energy power generations such as wind-power electricity generation
Energy carrier.Many prior arts utilize electrolyzed alkaline water process for making hydrogen at present, and such as Application No. 200910027704.7 is special
Profit describes a kind of new system for producing hydrogen by electrolyzing pure water under middle.But these existing inventions and technology be not by electrolytic hydrogen production
System is combined with the flexibility peak regulation and cooling water system of thermal power plant, and the hydrogen of output only compresses transport with steel cylinder, it is impossible to
Maximization production.
The content of the invention
The invention provides a kind of thermal power plant's electric power by electrolytic cell hydrogen generating system, by by electrolytic hydrogen production and thermal power plant
Flexibility peak regulation is combined, and the clean energy resource electric energy such as indirect utilization large-scale wind electricity, photovoltaic carrys out electrolytic hydrogen production, can annual four seasons solution
Wind is certainly abandoned, light is abandoned, abandons water, abandons core etc. and abandon clean energy resource power generation issues, the Peak Load of preciousness is provided for power network, meanwhile, it is raw
The Hydrogen Energy of production easily can be stored and transported, and can also be directly mixed in existing gas distributing system or directly for sale, increase
