Description

Hydrogen formation apparatus

Technical field

The utility model relates to the developmental technology of new energy resources field, specifically a kind of hydrogen formation apparatus that adopts the efficient hydrogen manufacturing of brine electrolysis cracking process.

Background technology

The energy is as the lifeblood of world economy, and the power of social development has been subjected to the great attention of various countries.Yet its reserves of fossil oil that account for world energy sources supply 90% are exhausted day by day.Having verified world's crude oil can be for utilizing 50-80 years again, and coal can be for utilizing 200-300 years again, and Sweet natural gas can be for utilizing 100 years again.And the use of fossil oil has caused the serious environmental pollution, and reason is that the CO2 that combustion of fossil fuel is emitted is most important greenhouse gases.In nearly more than 100 years, global ground medial temperature has risen 0.3-0.6 ℃, sea level rise 14-25cm.In addition, fossil oil skewness, reserves are limited, the war that causes by its with conflict of common occurrence.

Therefore, in the face of traditional fossil oil is bordering on exhaustion, because the global warming that burning mineral fuel causes quickens day by day, the city Air quality in a lot of cities, the world descends, for contention can source area the political instability factor problem of many threat human society survival and development such as increasingly sharpen, our thinking of having to: the human following outlet where? what will be mankind's energy tomorrow?

Hydrogen is gradually known together by common people as a kind of cleaning, efficient and resourceful new forms of energy.It has the following advantages:

1. clean.Only produce in the combustion of hydrogen process water to environment without any pollution, realize real " zero release ".

2. energy storage height.Burning 1 gram hydrogen can be emitted 140,000 joules heat, is about 3 times of burning 1 gram gasoline heat release.

3. service efficiency height.The heat that adopts catalyticcombustion hydrogen to produce is than the thermo-efficiency high 10-15% of conventional fossil oil; Be used for oil engine and produce power, than gasoline efficient high 15-25%.

4. the source is abundant.Contain a large amount of hydrogen in the water on occupation of land ball surface 71%, resource is very abundant.

5. be convenient to transportation.Defeated hydrogen cost is minimum, loses minimum.Article one, the hydrogen feeding pipe road of 0.91 meter of diameter is used for 950-1600 kilometers defeated hydrogen, and it is carried and can be equivalent to more than 10 times of 500,000 volts of ultra-high-tension power transmission line institute delivery of energies in the station.And build the required expense of such transport pipe, only for building 1/4-1/2 of ultra-high-tension power transmission line.

6. of many uses.Replace coal and oil with hydrogen, do not need existing technical equipment is done great transformation, present oil engine is reequiped a little and can be used.Substitute acetylene gas and oxygen and do metal solder, cutting process, its working efficiency exceeds more than 3 times.Also can be used for fuel cell, or convert solid-state hydrogen to as the standby removable energy.In a word, as new forms of energy, can substitute all power source fuel.

Hydrogen is the key research project of 21st century countries in the world scientific research circle, and China payes attention to the research and development of " Hydrogen Energy " too, and has listed among " national science and technology evolutionary operation(EVOP)-863 Program ".

Although hydrogen is one of the abundantest element of nature, natural hydrogen but seldom has on the ground, produces so can only rely on manually.But use as the energy, particularly common domestic fuel at first requires the hydrogen producing amount big, requires cost lower simultaneously, promptly has feasibility economically, and this is the choice criteria of hydrogen producing technology from now on.With regard to long-range and macroscopical with regard to, the main source of hydrogen is a water, should be the main direction of contemporary new and high technology with water-splitting hydrogen manufacturing.

Common brine electrolysis cracking hydrogen production method all is to adopt the conventional DC voltage stabilized source, and its shortcoming is: can not change the activated electrode characteristic of hydrogen generator, so efficient is very low, its effect can only be " getting half the result with twice the effort ".Be that power consumption is big, gas production rate is little, be not suitable for producing in batches.
